The only -way to see thread's stack platform-independently is to actually jump to -the saved context. That's what the _st_iterate_threads() function does. -Do the following to iterate over all threads: - -- set the _st_iterate_threads_flag to 1 in debugger -- set breakpoint at the _st_show_thread_stack() function - (which does nothing) -- call the _st_iterate_threads() function which jumps to the - next thread -- at each break you can explore thread's stack -- continue -- when iteration is complete, you return to the original - point (you can see thread id and a message as arguments of - the _st_show_thread_stack() function). - -You can call _st_iterate_threads() in three ways: - -- Insert it into your source code at the point you want to - go over threads. -- Just run application and this function will be called at - the first context switch. -- Call it directly from the debugger at any point. - -This works with gdb and dbx. - -Example using gdb: - -(gdb) set _st_iterate_threads_flag = 1 -(gdb) b _st_show_thread_stack -... -(gdb) call _st_iterate_threads() -... -(gdb) bt -... -(gdb) c -... -(gdb) bt -... -(gdb) c -... -and so on... - -_st_iterate_threads_flag will be set to 0 automatically -after iteration is over or you can set it to 0 at any time -to stop iteration. - -Sometimes gdb complains about SIGSEGV when you call a function -directly at gdb command-line. It can be ignored -- just call the -same function right away again, it works just fine. For example: - -(gdb) set _st_iterate_threads_flag = 1 -(gdb) b _st_show_thread_stack -Breakpoint 1 at 0x809bbbb: file sched.c, line 856. -(gdb) call _st_iterate_threads() -Program received signal SIGSEGV, Segmentation fault. -.... -(gdb) # just call the function again: -(gdb) call _st_iterate_threads() -Breakpoint 1, _st_show_thread_stack (thread=0x4017aee4, messg=0x80ae7a2 -"Iteration started") at sched.c:856 -856 } -.... - -You can use simple gdb command-line scripting to display -all threads and their stack traces at once: - -(gdb) while _st_iterate_threads_flag - >bt - >c - >end -.... - -Another script to stop at the thread with the specific thread id -(e.g., 0x40252ee4): - -(gdb) # set the flag again: -(gdb) set _st_iterate_threads_flag = 1 -(gdb) call _st_iterate_threads() -Breakpoint 1, _st_show_thread_stack (thread=0x4017aee4, messg=0x80ae7a2 -"Iteration started") at sched.c:856 -856 } -.... -(gdb) while thread != 0x40252ee4 - >c - >end -.... -.... -Breakpoint 1, _st_show_thread_stack (thread=0x40252ee4, messg=0x0) at -sched.c:856 -856 } -(gdb) bt -.... -(gdb) # don't want to continue iteration, unset the flag: -(gdb) set _st_iterate_threads_flag = 0 -(gdb) c -Continuing. -Breakpoint 1, _st_show_thread_stack (thread=0x0, messg=0x80ae78e "Iteration -completed") - at sched.c:856 -856 } -(gdb) c -Continuing. -(gdb) return -Make selected stack frame return now?

Terpstra's Darwin (MacOS X) port. - -o Support for many CPU architectures under Linux and *BSD. - -o Renamed private typedefs so they don't conflict with public ones any - more. - -o common.h now includes public.h for strict prototyping. - -o Joshua Levy's recommendation to make st_connect() and st_sendto() - accept const struct sockaddr pointers, as the originals do. - -o Clarified the documentation regarding blocking vs. non-blocking I/O. - -o Cygwin support. - -o Created the extensions directory. - -o Fixed warnings from ia64asm.S. - - -Changes from 1.2 to 1.3. ------------------------- -o Added st_read_resid() and st_write_resid() to allow the caller to know - how much data was transferred before an error occurred. Updated - documentation. - -o Updated project link, copyrights, and documentation regarding - timeouts. Added comment to st_connect(). - -o Optimized the _st_add_sleep_q() function in sched.c. Now we walk the - sleep queue *backward* when inserting a thread into it. When you - have lots (hundreds) of threads and several timeout values, it takes - a while to insert a thread at the appropriate point in the sleep - queue. The idea is that often this appropriate point is closer to - the end of the queue rather than the beginning. Measurements show - performance improves with this change. In any case this change - should do no harm. - -o Added a hint of when to define USE_POLL and when not to, to the - Makefile. - -o Added debugging support (files common.h and sched.c). See above. - -o Decreased the number of reallocations of _ST_POLLFDS in sched.c. - Inspired by Lev Walkin. - -o Fixed st_usleep(-1) and st_sleep(-1), and added a warning to the - documentation about too-large timeouts. - -o Linux/*BSD Alpha port. - -o Wesley W. Terpstra modernized the build process: - - properly build relocatable libraries under bsd and linux - - use library versioning - - added rpm spec file - - added debian/ files - See above for build instructions. - - -Changes from 1.1 to 1.2. ------------------------- -o Added st_randomize_stacks(). - -o Added a patch contributed by Sascha Schumann. - - -Changes from 1.0 to 1.1. ------------------------- -o Relicensed under dual MPL-GPL. - -o OpenBSD port. - -o Compile-time option to use poll() instead of select() for - event polling (see Makefile). - This is useful if you want to support a large number of open - file descriptors (larger than FD_SETSIZE) within a single - process. - -o Linux IA-64 port. - Two issues make IA-64 different from other platforms: - - - Besides the traditional call stack in memory, IA-64 uses the - general register stack. Thus each thread needs a backing store - for the register stack in addition to the memory stack. - - - Current implementation of setjmp()/longjmp() can not be used - for thread context-switching since it assumes that only one - register stack exists. Using special assembly functions for - context-switching is unavoidable. - -o Thread stack capping on IRIX. - This allows some profiling tools (such as SpeedShop) to know when - to stop unwinding the stack. Without this libexc, used by SpeedShop, - traces right off the stack and crashes. - -o Miscellaneous documentation additions. - - -COPYRIGHTS - -Portions created by SGI are Copyright (C) 2000 Silicon Graphics, Inc. -All Rights Reserved. diff --git a/trunk/3rdparty/st-srs/README.md b/trunk/3rdparty/st-srs/README.md deleted file mode 100644 index 60fc1a6518..0000000000 --- a/trunk/3rdparty/st-srs/README.md +++ /dev/null @@ -1,88 +0,0 @@ -# state-threads - -![](http://ossrs.net:8000/gif/v1/sls.gif?site=github.com&path=/srs/srsst) -[![](https://cloud.githubusercontent.com/assets/2777660/22814959/c51cbe72-ef92-11e6-81cc-32b657b285d5.png)](https://github.com/ossrs/srs/wiki/v1_CN_Contact#wechat) - -Fork from http://sourceforge.net/projects/state-threads, patched for [SRS](https://github.com/ossrs/srs/tree/2.0release). - -> See: https://github.com/ossrs/state-threads/blob/srs/README - -For original ST without any changes, checkout the [ST master branch](https://github.com/ossrs/state-threads/tree/master). - -## Branch SRS - -The branch [srs](https://github.com/ossrs/state-threads/tree/srs) will be patched the following patches: - -- [x] Patch [st.arm.patch](https://github.com/ossrs/srs/blob/2.0release/trunk/3rdparty/patches/1.st.arm.patch), for ARM. -- [x] Patch [st.osx.kqueue.patch](https://github.com/ossrs/srs/blob/2.0release/trunk/3rdparty/patches/3.st.osx.kqueue.patch), for osx. -- [x] Patch [st.disable.examples.patch](https://github.com/ossrs/srs/blob/2.0release/trunk/3rdparty/patches/4.st.disable.examples.patch), for ubuntu. -- [x] [Refine TAB of code](https://github.com/ossrs/state-threads/compare/c2001d30ca58f55d72a6cc6b9b6c70391eaf14db...d2101b26988b0e0db0aabc53ddf452068c1e2cbc). -- [x] Merge from [michaeltalyansky](https://github.com/michaeltalyansky/state-threads) and [xzh3836598](https://github.com/ossrs/state-threads/commit/9a17dec8f9c2814d93761665df7c5575a4d2d8a3), support [ARM](https://github.com/ossrs/state-threads/issues/1). -- [x] Merge from [toffaletti](https://github.com/toffaletti/state-threads), support [valgrind](https://github.com/ossrs/state-threads/issues/2) for ST. -- [x] Patch [st.osx10.14.build.patch](https://github.com/ossrs/srs/blob/2.0release/trunk/3rdparty/patches/6.st.osx10.14.build.patch), for osx 10.14 build. -- [x] Support macro `MD_ST_NO_ASM` to disable ASM, [#8](https://github.com/ossrs/state-threads/issues/8). -- [x] Merge patch [srs#1282](https://github.com/ossrs/srs/issues/1282#issuecomment-445539513) to support aarch64, [#9](https://github.com/ossrs/state-threads/issues/9). - -## Docs - -* Introduction: http://ossrs.github.io/state-threads/docs/st.html -* API reference: http://ossrs.github.io/state-threads/docs/reference.html -* Programming notes: http://ossrs.github.io/state-threads/docs/notes.html - -## Usage - -Get code: - -``` -git clone https://github.com/ossrs/state-threads.git st-1.9 && -git checkout -b srs origin/srs -``` - -For Linux: - -``` -make linux-debug EXTRA_CFLAGS="-DMD_HAVE_EPOLL" -``` - -For OSX: - -``` -make darwin-debug EXTRA_CFLAGS="-DMD_HAVE_KQUEUE" -``` - -Linux with valgrind: - -``` -make linux-debug EXTRA_CFLAGS="-DMD_VALGRIND" -``` - -> Remark: User must install valgrind, for instance, in centos6 `sudo yum install -y valgrind valgrind-devel`. - -Linux with valgrind and epoll: - -``` -make linux-debug EXTRA_CFLAGS="-DMD_HAVE_EPOLL -DMD_VALGRIND" -``` - -For OSX, user must specifies the valgrind header files: - -``` -make darwin-debug EXTRA_CFLAGS="-DMD_HAVE_KQUEUE -DMD_VALGRIND -I/usr/local/include" -``` - -> Remark: Latest OSX does not support ST, please use docker to run ST. - -## Valgrind - -How to debug with gdb under valgrind, read [valgrind manual](http://valgrind.org/docs/manual/manual-core-adv.html#manual-core-adv.gdbserver-simple). - -About startup parameters, read [valgrind cli](http://valgrind.org/docs/manual/mc-manual.html#mc-manual.options). - -Important cli options: - -1. `--undef-value-errors= [default: yes]`, Controls whether Memcheck reports uses of undefined value errors.

Porting

-The State Threads library uses OS concepts that are available in some -form on most UNIX platforms, making the library very portable across -many flavors of UNIX. However, there are several parts of the library -that rely on platform-specific features. Here is the list of such parts: -

-

    -
  • Thread context initialization: Two ingredients of the -jmp_buf -data structure (the program counter and the stack pointer) have to be -manually set in the thread creation routine. The jmp_buf data -structure is defined in the setjmp.h header file and differs from -platform to platform. Usually the program counter is a structure member -with PC in the name and the stack pointer is a structure member -with SP in the name. One can also look in the -Netscape's NSPR library source -which already has this code for many UNIX-like platforms -(mozilla/nsprpub/pr/include/md/*.h files). -

    -Note that on some BSD-derived platforms _setjmp(3)/_longjmp(3) -calls should be used instead of setjmp(3)/longjmp(3) (that is -the calls that manipulate only the stack and registers and do not -save and restore the process's signal mask).

    • -

    -Starting with glibc 2.4 on Linux the opacity of the jmp_buf data -structure is enforced by setjmp(3)/longjmp(3) so the -jmp_buf ingredients cannot be accessed directly anymore (unless -special environmental variable LD_POINTER_GUARD is set before application -execution). To avoid dependency on custom environment, the State Threads -library provides setjmp/longjmp replacement functions for -all Intel CPU architectures. Other CPU architectures can also be easily -supported (the setjmp/longjmp source code is widely available for -many CPU architectures). -

    -

  • High resolution time function: Some platforms (IRIX, Solaris) -provide a high resolution time function based on the free running hardware -counter. This function returns the time counted since some arbitrary -moment in the past (usually machine power up time). It is not correlated in -any way to the time of day, and thus is not subject to resetting, -drifting, etc. This type of time is ideal for tasks where cheap, accurate -interval timing is required. If such a function is not available on a -particular platform, the gettimeofday(3) function can be used -(though on some platforms it involves a system call). -

    -

  • The stack growth direction: The library needs to know whether the -stack grows toward lower (down) or higher (up) memory addresses. -One can write a simple test program that detects the stack growth direction -on a particular platform.
    • -

    -

  • Non-blocking attribute inheritance: On some platforms (e.g. IRIX) -the socket created as a result of the accept(2) call inherits the -non-blocking attribute of the listening socket. One needs to consult the manual -pages or write a simple test program to see if this applies to a specific -platform.
    • -

    -

  • Anonymous memory mapping: The library allocates memory segments -for thread stacks by doing anonymous memory mapping (mmap(2)). This -mapping is somewhat different on SVR4 and BSD4.3 derived platforms. -

    -The memory mapping can be avoided altogether by using malloc(3) for -stack allocation. In this case the MALLOC_STACK macro should be -defined.

    • -
-

-All machine-dependent feature test macros should be defined in the -md.h header file. The assembly code for setjmp/longjmp -replacement functions for all CPU architectures should be placed in -the md.S file. -

-The current version of the library is ported to: -

    -
  • IRIX 6.x (both 32 and 64 bit)
    • -
  • Linux (kernel 2.x and glibc 2.x) on x86, Alpha, MIPS and MIPSEL, - SPARC, ARM, PowerPC, 68k, HPPA, S390, IA-64, and Opteron (AMD-64)
    • -
  • Solaris 2.x (SunOS 5.x) on x86, AMD64, SPARC, and SPARC-64

Signals

-Signal handling in an application using State Threads should be treated the -same way as in a classical UNIX process application. There is no such -thing as per-thread signal mask, all threads share the same signal handlers, -and only asynchronous-safe functions can be used in signal handlers. -However, there is a way to process signals synchronously by converting a -signal event to an I/O event: a signal catching function does a write to -a pipe which will be processed synchronously by a dedicated signal handling -thread. The following code demonstrates this technique (error handling is -omitted for clarity): -
-
-/* Per-process pipe which is used as a signal queue. */
-/* Up to PIPE_BUF/sizeof(int) signals can be queued up. */
-int sig_pipe[2];
-
-/* Signal catching function. */
-/* Converts signal event to I/O event. */
-void sig_catcher(int signo)
-{
-  int err;
-
-  /* Save errno to restore it after the write() */
-  err = errno;
-  /* write() is reentrant/async-safe */
-  write(sig_pipe[1], &signo, sizeof(int));
-  errno = err;
-}
-
-/* Signal processing function. */
-/* This is the "main" function of the signal processing thread. */
-void *sig_process(void *arg)
-{
-  st_netfd_t nfd;
-  int signo;
-
-  nfd = st_netfd_open(sig_pipe[0]);
-
-  for ( ; ; ) {
-    /* Read the next signal from the pipe */
-    st_read(nfd, &signo, sizeof(int), ST_UTIME_NO_TIMEOUT);
-
-    /* Process signal synchronously */
-    switch (signo) {
-    case SIGHUP:
-      /* do something here - reread config files, etc. */
-      break;
-    case SIGTERM:
-      /* do something here - cleanup, etc. */
-      break;
-      /*      .
-              .
-         Other signals
-              .
-              .
-      */
-    }
-  }
-
-  return NULL;
-}
-
-int main(int argc, char *argv[])
-{
-  struct sigaction sa;
-        .
-        .
-        .
-
-  /* Create signal pipe */
-  pipe(sig_pipe);
-
-  /* Create signal processing thread */
-  st_thread_create(sig_process, NULL, 0, 0);
-
-  /* Install sig_catcher() as a signal handler */
-  sa.sa_handler = sig_catcher;
-  sigemptyset(&sa.sa_mask);
-  sa.sa_flags = 0;
-  sigaction(SIGHUP, &sa, NULL);
-
-  sa.sa_handler = sig_catcher;
-  sigemptyset(&sa.sa_mask);
-  sa.sa_flags = 0;
-  sigaction(SIGTERM, &sa, NULL);
-
-        .
-        .
-        .
-      
-}
-
-
-

-Note that if multiple processes are used (see below), the signal pipe should -be initialized after the fork(2) call so that each process has its -own private pipe. -

- - -

Intra-Process Synchronization

-Due to the event-driven nature of the library scheduler, the thread context -switch (process state change) can only happen in a well-known set of -library functions. This set includes functions in which a thread may -"block": I/O functions (st_read(), st_write(), etc.), -sleep functions (st_sleep(), etc.), and thread synchronization -functions (st_thread_join(), st_cond_wait(), etc.). As a result, -process-specific global data need not to be protected by locks since a thread -cannot be rescheduled while in a critical section (and only one thread at a -time can access the same memory location). By the same token, -non thread-safe functions (in a traditional sense) can be safely used with -the State Threads. The library's mutex facilities are practically useless -for a correctly written application (no blocking functions in critical -section) and are provided mostly for completeness. This absence of locking -greatly simplifies an application design and provides a foundation for -scalability. -

- - -

Inter-Process Synchronization

-The State Threads library makes it possible to multiplex a large number -of simultaneous connections onto a much smaller number of separate -processes, where each process uses a many-to-one user-level threading -implementation (N of M:1 mappings rather than one M:N -mapping used in native threading libraries on some platforms). This design -is key to the application's scalability. One can think about it as if a -set of all threads is partitioned into separate groups (processes) where -each group has a separate pool of resources (virtual address space, file -descriptors, etc.). An application designer has full control of how many -groups (processes) an application creates and what resources, if any, -are shared among different groups via standard UNIX inter-process -communication (IPC) facilities.

-There are several reasons for creating multiple processes: -

-

    -
  • To take advantage of multiple hardware entities (CPUs, disks, etc.) -available in the system (hardware parallelism).
    • -

    -

  • To reduce risk of losing a large number of user connections when one of -the processes crashes. For example, if C user connections (threads) -are multiplexed onto P processes and one of the processes crashes, -only a fraction (C/P) of all connections will be lost.
    • -

    -

  • To overcome per-process resource limitations imposed by the OS. For -example, if select(2) is used for event polling, the number of -simultaneous connections (threads) per process is -limited by the FD_SETSIZE parameter (see select(2)). -If FD_SETSIZE is equal to 1024 and each connection needs one file -descriptor, then an application should create 10 processes to support 10,000 -simultaneous connections.
    • -
-

-Ideally all user sessions are completely independent, so there is no need for -inter-process communication. It is always better to have several separate -smaller process-specific resources (e.g., data caches) than to have one large -resource shared (and modified) by all processes. Sometimes, however, there -is a need to share a common resource among different processes. In that case, -standard UNIX IPC facilities can be used. In addition to that, there is a way -to synchronize different processes so that only the thread accessing the -shared resource will be suspended (but not the entire process) if that resource -is unavailable. In the following code fragment a pipe is used as a counting -semaphore for inter-process synchronization: -

-#ifndef PIPE_BUF
-#define PIPE_BUF 512  /* POSIX */
-#endif
-
-/* Semaphore data structure */
-typedef struct ipc_sem {
-  st_netfd_t rdfd;  /* read descriptor */
-  st_netfd_t wrfd;  /* write descriptor */
-} ipc_sem_t;
-
-/* Create and initialize the semaphore. Should be called before fork(2). */
-/* 'value' must be less than PIPE_BUF. */
-/* If 'value' is 1, the semaphore works as mutex. */
-ipc_sem_t *ipc_sem_create(int value)
-{
-  ipc_sem_t *sem;
-  int p[2];
-  char b[PIPE_BUF];
-
-  /* Error checking is omitted for clarity */
-  sem = malloc(sizeof(ipc_sem_t));
-
-  /* Create the pipe */
-  pipe(p);
-  sem->rdfd = st_netfd_open(p[0]);
-  sem->wrfd = st_netfd_open(p[1]);
-
-  /* Initialize the semaphore: put 'value' bytes into the pipe */
-  write(p[1], b, value);
-
-  return sem;
-}
-
-/* Try to decrement the "value" of the semaphore. */
-/* If "value" is 0, the calling thread blocks on the semaphore. */
-int ipc_sem_wait(ipc_sem_t *sem)
-{
-  char c;
-
-  /* Read one byte from the pipe */
-  if (st_read(sem->rdfd, &c, 1, ST_UTIME_NO_TIMEOUT) != 1)
-    return -1;
-
-  return 0;
-}
-
-/* Increment the "value" of the semaphore. */
-int ipc_sem_post(ipc_sem_t *sem)
-{
-  char c;
-
-  if (st_write(sem->wrfd, &c, 1, ST_UTIME_NO_TIMEOUT) != 1)
-    return -1;
-
-  return 0;
-}
-
-
-

- -Generally, the following steps should be followed when writing an application -using the State Threads library: -

-

    -
  1. Initialize the library (st_init()).
    2. -

    -

  2. Create resources that will be shared among different processes: - create and bind listening sockets, create shared memory segments, IPC - channels, synchronization primitives, etc.
    3. -

    -

  3. Create several processes (fork(2)). The parent process should - either exit or become a "watchdog" (e.g., it starts a new process when - an existing one crashes, does a cleanup upon application termination, - etc.).
    4. -

    -

  4. In each child process create a pool of threads - (st_thread_create()) to handle user connections.
    5. -
-

- - -

Non-Network I/O

- -The State Threads architecture uses non-blocking I/O on -st_netfd_t objects for concurrent processing of multiple user -connections. This architecture has a drawback: the entire process and -all its threads may block for the duration of a disk or other -non-network I/O operation, whether through State Threads I/O functions, -direct system calls, or standard I/O functions. (This is applicable -mostly to disk reads; disk writes are usually performed -asynchronously -- data goes to the buffer cache to be written to disk -later.) Fortunately, disk I/O (unlike network I/O) usually takes a -finite and predictable amount of time, but this may not be true for -special devices or user input devices (including stdin). Nevertheless, -such I/O reduces throughput of the system and increases response times. -There are several ways to design an application to overcome this -drawback: - -

-

 -

- - -

Timeouts

- -The timeout parameter to st_cond_timedwait() and the -I/O functions, and the arguments to st_sleep() and -st_usleep() specify a maximum time to wait since the last -context switch not since the beginning of the function call. - -

The State Threads' time resolution is actually the time interval -between context switches. That time interval may be large in some -situations, for example, when a single thread does a lot of work -continuously. Note that a steady, uninterrupted stream of network I/O -qualifies for this description; a context switch occurs only when a -thread blocks. - -

If a specified I/O timeout is less than the time interval between -context switches the function may return with a timeout error before -that amount of time has elapsed since the beginning of the function -call. For example, if eight milliseconds have passed since the last -context switch and an I/O function with a timeout of 10 milliseconds -blocks, causing a switch, the call may return with a timeout error as -little as two milliseconds after it was called. (On Linux, -select()'s timeout is an upper bound on the amount of -time elapsed before select returns.) Similarly, if 12 ms have passed -already, the function may return immediately. - -

In almost all cases I/O timeouts should be used only for detecting a -broken network connection or for preventing a peer from holding an idle -connection for too long. Therefore for most applications realistic I/O -timeouts should be on the order of seconds. Furthermore, there's -probably no point in retrying operations that time out. Rather than -retrying simply use a larger timeout in the first place. - -

The largest valid timeout value is platform-dependent and may be -significantly less than INT_MAX seconds for select() -or INT_MAX milliseconds for poll(). Generally, you -should not use timeouts exceeding several hours. Use -ST_UTIME_NO_TIMEOUT (-1) as a special value to -indicate infinite timeout or indefinite sleep. Use -ST_UTIME_NO_WAIT (0) to indicate no waiting at all. - -

Types

- -The State Thread library defines the following types in the st.h -header file: -

-

-
st_thread_t
-
st_cond_t
-
st_mutex_t
-
st_utime_t
-
st_netfd_t
-
-

-

-

- - -

st_thread_t

- -Thread type. -

-

Syntax
- -
-#include <st.h>
-
-typedef void *  st_thread_t;
-
-

-

Description
- -A thread is represented and identified by a pointer to an opaque data -structure. This pointer is a required parameter for most of the functions -that operate on threads. -

-The thread identifier remains valid until the thread returns from its root -function and, if the thread was created joinable, is joined. -

-

-

- - -

st_cond_t

- -Condition variable type. -

-

Syntax
- -
-#include <st.h>
-
-typedef void *  st_cond_t;
-
-

-

Description
- -A condition variable is an opaque object identified by a pointer. -Condition variables provide synchronization primitives to wait for or wake -up threads waiting for certain conditions to be satisfied. -

-In the State Threads library there is no need to lock a mutex before -waiting on a condition variable. -

-

-

- - -

st_mutex_t

- -Mutex type. -

-

Syntax
- -
-#include <st.h>
-
-typedef void *  st_mutex_t;
-
-

-

Description
- -A mutex is an opaque object identified by a pointer. -Mutual exclusion locks (mutexes) are used to serialize the execution of -threads through critical sections of code. -

-If application using the State Threads library is written with no -I/O or control yielding in critical sections (that is no -blocking functions in critical sections), then there is -no need for mutexes.

-These mutexes can only be used for intra-process thread synchronization. -They cannot be used for inter-process synchronization. -

-

-

- - -

st_utime_t

- -High resolution time type ("u" stands for "micro"). -

-

Syntax
- -
-#include <st.h>
-
-typedef unsigned long long  st_utime_t;
-
-

-

Description
- -This datatype (unsigned 64-bit integer) represents high-resolution real time -expressed in microseconds since some arbitrary time in the past. It is not -correlated in any way to the time of day. -

-

-

- - -

st_netfd_t

- -File descriptor type. -

-

Syntax
- -
-#include <st.h>
-
-typedef void *  st_netfd_t;
-
-

-

Description
- -This datatype typically represents any open end point of network -communication (socket, end point of a pipe, FIFO, etc.) but can -encapsulate any open file descriptor. Objects of this type are -identified by a pointer to an opaque data structure. - -

-

-

- - -

st_switch_cb_t

- -Context switch callback function type. -

-

Syntax
- -
-#include <st.h>
-
-typedef void (*st_switch_cb_t)(void);
-
-

-

Description
- -This datatype is a convenience type for describing a pointer -to a function that will be called when a thread is set to stop -or set to run. -This feature is available only when ST_SWITCH_CB is defined -in <st.h>. - -

-

-

- - -

Error Handling

- - -All State Threads library non-void functions return on success either a -non-negative integer or a pointer to a newly created object (constructor-type -functions). On failure they return either -1 or a NULL -pointer respectively and set global errno to indicate the error. -It is safe to use errno because it is set right before the function -return and only one thread at a time can modify its value.

-The perror(3) function can be used to produce an error message on the -standard error output. -

-

-

- - -

Library Initialization

- -

-

-
st_init()
-
st_getfdlimit()
-
st_set_eventsys()
-
st_get_eventsys()
-
st_get_eventsys_name()
-

-These functions operate on a callback function of type -st_switch_cb_t: -

st_set_switch_in_cb()
-
st_set_switch_out_cb()
-
-

-

-

- - -

st_init()

- -Initializes the runtime. -

-

Syntax
- -
-#include <st.h>
-
-int st_init(void);
-
-

-

Parameters
-None. -

-

Returns
-Upon successful completion, a value of 0 is returned. -Otherwise, a value of -1 is returned and errno is set -to indicate the error. -

-

Description
-This function initializes the library runtime. It should be called near -the beginning of the application's main() function before any other -State Threads library function is called.

-Among other things, this function limits the number of open file descriptors -to the OS imposed per-process maximum number or, if select(2) is -used, to FD_SETSIZE, whichever is less (getrlimit(2)). -This limit can be -retrieved by st_getfdlimit(). It also sets the -disposition of the SIGPIPE signal to SIG_IGN (to be ignored) -(signal(5)). -

-Unlike POSIX threads, a new process created by the fork(2) system -call is an exact copy of the calling process and all state threads -which are running in the parent do exist in the child. That means that -st_init() may be called either before or after multiple processes -are created by fork(2). -

-If the library runtime is not properly initialized (e.g., st_init() -is accidentally omitted), then the process will receive either an arithmetic -exception (SIGFPE or SIGTRAP) or segmentation fault (SIGSEGV) signal upon -new thread creation or the first context switch, respectively. -

-

-

- -

st_getfdlimit()

- -Returns the maximum number of file descriptors that the calling process -can open. -

-

Syntax
- -
-#include <st.h>
-
-int st_getfdlimit(void);
-
-

-

Parameters
-None. -

-

Returns
-The maximum number of file descriptors that the calling process can open. -If this function is called before the library is successfully initialized by -st_init(), a value of -1 is returned. -

-

Description
-This function returns the limit on the number of open file descriptors which -is set by the st_init() function. -

-

-

- - -

st_set_eventsys()

- -Sets event notification mechanism. -

-

Syntax
- -
-#include <st.h>
-
-int st_set_eventsys(int eventsys);
-
-

-

Parameters
-st_set_eventsys() has the following parameter:

-eventsys

-An integer value identifying selected event notification mechanism. The -following values are defined in the st.h header file: -

- - - - - - - - - - - - - - - -
ST_EVENTSYS_DEFAULTUse default event notification mechanism. Usually it's select(2) -but if the library was compiled with the USE_POLL macro defined -then the default is poll(2).
ST_EVENTSYS_SELECTUse select(2) as an event notification mechanism.
ST_EVENTSYS_POLLUse poll(2) as an event notification mechanism.
ST_EVENTSYS_ALTUse an alternative event notification mechanism. The actual -mechanism selected depends on OS support. For example, epoll(4) -will be used on Linux if supported and kqueue(2) will be used -on FreeBSD/OpenBSD. If the OS supports no alternative event -notification mechanism, setting ST_EVENTSYS_ALT has no effect -and the ST_EVENTSYS_DEFAULT mechanism will be used.
-

-

Returns
-Upon successful completion, a value of 0 is returned. -Otherwise, a value of -1 is returned and errno is set -to indicate the error:

- - - - - -
EINVAL -The supplied eventsys parameter has an invalid value. -
EBUSY -The event notification mechanism has already been set. -
-

-

Description
-This function sets the event notification mechanism that will be used by -the State Threads library. To have any effect, it must be called -before the st_init() function which performs -the actual initialization. If st_set_eventsys() is not called, -st_init() will set the ST_EVENTSYS_DEFAULT -mechanism. The mechanism cannot be changed once set. -

-There are no strict rules for selecting an event notification -mechanism. The "best" one depends on how your application behaves. -Try a few to see which one works best for you. As a rule of -thumb, you should use the ST_EVENTSYS_ALT mechanism if your -application deals with a very large number of network connections of -which only a few are active at once. -

-

-

- -

st_get_eventsys()

- -Returns the integer value identifying the event notification mechanism -being used by the State Threads library. -

-

Syntax
- -
-#include <st.h>
-
-int st_get_eventsys(void);
-
-

-

Parameters
-None. -

-

Returns
-The integer value identifying the current event notification mechanism. -This value can be one of the following (see st_set_eventsys()): -ST_EVENTSYS_SELECT, ST_EVENTSYS_POLL, or -ST_EVENTSYS_ALT. Future versions of the library may return other -values. If a mechanism hasn't been set yet, a value of -1 is returned. -

-

Description
-This function returns the integer value identifying the event notification -mechanism which is actually being used by the State Threads library. -

-

-

- -

st_get_eventsys_name()

- -Returns the name of the event notification mechanism being used by the -State Threads library. -

-

Syntax
- -
-#include <st.h>
-
-const char *st_get_eventsys_name(void);
-
-

-

Parameters
-None. -

-

Returns
-The string identifying the current event notification mechanism. If a -mechanism hasn't been set yet (see st_set_eventsys()), an empty string is -returned. Possible return values are "select", -"poll", "kqueue", or "epoll". Future versions -of the library may return other values. -

-

Description
-This function returns the string identifying the event notification -mechanism which is actually being used by the State Threads library. -

-

st_set_switch_out_cb()

- -Set the optional callback function for thread switches. -

-

Syntax
- -
-#include <st.h>
-
-st_switch_cb_t st_set_switch_in_cb(st_switch_cb_t cb);
-st_switch_cb_t st_set_switch_out_cb(st_switch_cb_t cb);
-
-

-

Parameters
-st_set_switch_in_cb() and st_set_switch_out_cb() have the -following parameter:

-cb

-A function to be called when a thread is resumed and stopped respectively.

-

Returns
-The previous callback function pointer. -

-

Description
-These functions set the callback for when a thread is resumed and stopped -respectively. After being called any thread switch will call the callback. -Use a NULL pointer to disable the callback (this is the default). -Use st_thread_self() or thread -specific data to differentiate between threads.

-These functions can be called at any time.

-This feature is available only when ST_SWITCH_CB is defined -in <st.h>. -

-

-

- - -

st_thread_create()

- -Creates a new thread. -

-

Syntax
- -
-#include <st.h>
-
-st_thread_t st_thread_create(void *(*start)(void *arg), void *arg,
-                             int joinable, int stack_size);
-
-
-

-

Parameters
-st_thread_create() has the following parameters:

-start

-A pointer to the thread's start function, which is called as the root of the -new thread. Return from this function terminates a thread.

-arg

-A pointer to the root function's only parameter.

-joinable

-Specifies whether the thread is joinable or unjoinable. If this parameter -is zero, the thread is unjoinable. Otherwise, it is joinable. -See also st_thread_join().

-stack_size

-Specifies your preference for the size of the stack, in bytes, associated -with the newly created thread. If you pass zero in this parameter, the -default stack size will be used. The default stack size is 128 KB on IA-64 -and 64 KB on all other platforms. On IA-64 only a half of stack_size -bytes is used for the memory stack. The other half is used for the register -stack backing store. -

-

Returns
-Upon successful completion, a new thread identifier is returned (this -identifier remains valid until the thread returns from its start function). -Otherwise, NULL is returned and errno is set -to indicate the error. -

-

Description
-This function creates a new thread. Note that the total number of threads -created by the application is limited by the amount of swap space available. -Upon thread creation, stack_size bytes are reserved on the swap -space. The stack pages are not actually used (valid) until touched by the -application. -

-

-

- -

st_thread_exit()

- -Terminates the calling thread. -

-

Syntax
- -
-#include <st.h>
-
-void st_thread_exit(void *retval);
-
-

-

Parameters
-st_thread_exit() has the following parameters:

-retval

-If the thread is joinable, then the value retval may be retrieved -by st_thread_join(). If a thread returns from its -start function, it acts as if it had called st_thread_exit() with -retval as the value returned. -

-

Returns
-Nothing. -

-

Description
-This function terminates the calling thread. When a thread exits, per-thread -private data is destroyed by invoking the destructor function for any -non-NULL thread specific values associated with active keys (see -st_key_create()). This function is implicitly called -when a thread returns from its start function.

-When the last thread terminates the process exits with a zero status value. -

-

-

- -

st_thread_join()

- -Blocks the calling thread until a specified thread terminates. -

-

Syntax
- -
-#include <st.h>
-
-int st_thread_join(st_thread_t thread, void **retvalp);
-
-

-

Parameters
-st_thread_join() has the following parameters:

-thread

-A valid identifier for the thread that is to be joined.

-retvalp

-If this parameter is not NULL, then the exit value of the -thread will be placed in the location referenced by this parameter -(see st_thread_exit()). -

-

Returns
-Upon successful completion, a value of 0 is returned. -Otherwise, a value of -1 is returned and errno is set -to indicate the error:

- - - - - -
EINVALTarget thread is unjoinable.
EINVALOther thread already waits on the same -joinable thread.
EDEADLKTarget thread is the same as the -calling thread.
EINTRCurrent thread was interrupted by -st_thread_interrupt().
-

-

Description
-This function is used to synchronize the termination of a thread and possibly -retrieve its exit value. Several threads cannot wait for the same thread -to complete - one of the calling threads operates successfully, and the others -terminate with the error. The calling thread is not blocked if the target -thread has already terminated. -

-

-

- -

st_thread_self()

- -Identifies the calling thread. -

-

Syntax
- -
-#include <st.h>
-
-st_thread_t st_thread_self(void);
-
-

-

Parameters
-None. -

-

Returns
-Always returns a valid reference to the calling thread - a self-identity. -

-

Description
-This function identifies the calling thread. This is the same identifier -that the creating thread obtains from -st_thread_create(). -

-

-

- -

st_thread_interrupt()

- -Interrupts a target thread. -

-

Syntax
- -
-#include <st.h>
-
-void st_thread_interrupt(st_thread_t thread);
-
-

-

Parameters
-st_thread_interrupt() has the following parameters:

-thread

-A valid identifier for the thread being interrupted. -

-

Returns
-Nothing. -

-

Description
-This function interrupts (unblocks) a target thread that is blocked in one -of the blocking functions. A function that was interrupted -returns an error and sets errno to EINTR. It is up to -the target thread to act upon an interrupt (e.g., it may exit or just -abort the current transaction).

-Note: State Threads library functions are never interrupted by a -caught signal. A blocking library function returns an error and sets -errno to EINTR only if the current thread was -interrupted via st_thread_interrupt(). -

-If a target thread is already runnable or running (e.g., it is a newly -created thread or calling thread itself), this function will prevent it -from subsequent blocking. In other words, the interrupt will be "delivered" -only when a target thread is about to block. -

-

-

- -

st_sleep(), st_usleep()

- -Suspends current thread for a specified amount of time. -

-

Syntax
- -
-#include <st.h>
-
-int st_sleep(int secs);
-
-int st_usleep(st_utime_t usecs);
-
-

-

Parameters
-st_sleep() has the following parameters:

-secs

-The number of seconds you want the thread to sleep for. -

-st_usleep() has the following parameters:

-usecs

-The number of microseconds you want the thread to sleep for. This parameter -is a variable of type st_utime_t. -

-

Returns
-Upon successful completion, a value of 0 is returned. -Otherwise, a value of -1 is returned and errno is set -to indicate the error:

- - -
EINTRThe current thread was interrupted by -st_thread_interrupt().
-

-

Description
-These functions suspend the calling thread from execution for a specified -number of seconds (st_sleep()) or microseconds (st_usleep()). -

- -If zero is passed as a parameter to st_sleep(), or -ST_UTIME_NO_WAIT (0) is passed to -st_usleep(), the calling thread yields, thus potentially -allowing another thread to run. - -

- -If -1 is passed as a parameter to st_sleep(), or -ST_UTIME_NO_TIMEOUT (-1) is passed to -st_usleep(), the calling thread will be suspended permanently. -It can be resumed again by interrupting it via st_thread_interrupt(). - -

-

-

- -

st_randomize_stacks()

- -Turns stack base address randomization on or off. -

-

Syntax
- -
-#include <st.h>
-
-int st_randomize_stacks(int on);
-
-

-

Parameters
-st_randomize_stacks() has the following parameters:

-on

-If this parameter has a non-zero value, the State Threads library -randomizes the base addresses of stacks allocated for threads created -after this call. Otherwise new threads' stacks are typically page -aligned. -

-

Returns
-The previous state of stack randomization (a value of 0 if it -was off and a non-zero value otherwise). -

-

Description
-Randomizing state threads' stack bases may improve cache performance on -some systems when large numbers of state threads all perform roughly the -same work, as when they all start from the same root function. On many -modern systems the performance increase is negligible. You should -compare your application's performance with this feature on and off to -see if you really need it. -

-When randomization is enabled, new stacks are allocated one page larger -to accomodate the randomization. -

-This call affects only threads created afterward. It has no effect on -existing threads. -

-

-

- - -

Per-Thread Private Data

- -These functions allow to associate private data with each of the threads in -a process. -

-

-
st_key_create()
-
st_key_getlimit()
-
st_thread_setspecific()
-
st_thread_getspecific()
-
-

-

-

- -

st_key_create()

- -Creates a key (non-negative integer) that can be used by all -threads in the process to get and set thread-specific data. -

-

Syntax
- -
-#include <st.h>
-
-int st_key_create(int *keyp, void (*destructor)(void *));
-
-

-

Parameters
-st_key_create() has the following parameters:

-keyp

-The newly created key is returned in the memory pointed to by this parameter. -The new key can be used with -st_thread_setspecific() and -st_thread_getspecific().

-destructor

-Specifies an optional destructor function for the private data associated -with the key. This function can be specified as NULL. -Upon thread exit (see st_thread_exit()), if a key -has a non-NULL destructor and has a non-NULL value -associated with that key, then the destructor function will be -called with the associated value. -

-

Returns
-Upon successful completion, a value of 0 is returned. -Otherwise, a value of -1 is returned and errno is set -to indicate the error:

- - -
EAGAINThe limit on the total number of keys per -process has been exceeded (see st_key_getlimit()). -
-

-

Description
-If this function is successful, every thread in the same process is capable -of associating private data with the new key. After a new key is created, all -active threads have the value NULL associated with that key. -After a new thread is created, the value NULL is associated with -all keys for that thread. If a non-NULL destructor function is -registered with a new key, it will be called at one of two times, as long as -the private data is not NULL: - -

-The key maintains independent data values for each binding thread. A thread -can get access only to its own thread-specific data. There is no way to -deallocate a private data key once it is allocated. -

-

-

- -

st_key_getlimit()

- -Returns the key limit. -

-

Syntax
- -
-#include <st.h>
-
-int st_key_getlimit(void);
-
-

-

Parameters
-None. -

-

Returns
-The limit on the total number of keys per process. -

-

-key

-This parameter represents a key with which thread-specific data is associated. -

-value

-The per-thread private data, or more likely, a pointer to the data which is -associated with key. -

-

Returns
-Upon successful completion, a value of 0 is returned. -Otherwise, a value of -1 is returned and errno is set -to indicate the error:

- - - -
EINVALThe specified key is invalid.
-

-

Description
-This function associates a thread-specific value with key. -Different threads may bind different values to the same key.

-If the thread already has non-NULL private data associated with -key, and if the destructor function for that key is not -NULL, this destructor function will be called before setting the -new data value. -

-

-

- -

st_thread_getspecific()

- -Retrieves the per-thread private data for the current thread. -

-

Syntax
- -
-#include <st.h>

Returns
-The thread-specific data associated with key. If no data is -associated with key, then NULL is returned. -

-

Description
-This function returns the calling thread's value that is bound to the -specified key (see -st_thread_setspecific()). -

-

-

- - -

st_utime()

- -Returns current high-resolution time. -

-

Syntax
- -
-#include <st.h>
-
-st_utime_t st_utime(void);
-
-

-

Parameters
-None. -

-

Returns
-Current high-resolution time value of type -st_utime_t. -

-

Description
-This function returns the current high-resolution time. Time is -expressed as microseconds since some arbitrary time in the past. It is -not correlated in any way to the time of day. See also st_utime_t and st_time(). -

-

-

- -

st_set_utime_function()

- -Set high-resolution time function. -

-

Syntax
- -
-#include <st.h>
-
-int st_set_utime_function(st_utime_t (*func)(void));
-
-

-

Parameters
-st_set_utime_function() has the following parameters:

-func

-This function will be called to get high-resolution time instead of the -default st_utime() function. It must return -number of microseconds since some arbitrary time in the past. -

-

Returns
-Upon successful completion, a value of 0 is returned. -Otherwise, a value of -1 is returned and errno is set -to EINVAL to indicate the error. -

-

Description
-This function may be called to replace the default implementation of the -st_utime() function. It must be called before the ST -library has been initialized (see st_init()). -The user-provided function func will be invoked whenever -st_utime() is called to obtain current high-resolution time. -Replacing default implementation may be useful, for example, for taking -advantage of high performance CPU cycle counters. -

-

-

- -

st_timecache_set()

- -Turns the time caching on or off. -

-

Syntax
- -
-#include <st.h>
-
-int st_timecache_set(int on);
-
-

-

Parameters
-st_timecache_set() has the following parameters:

-on

-If this parameter has a non-zero value, the time caching is turned on -(enabled). Otherwise, the time caching is turned off (disabled). -By default time caching is disabled. -

-

Returns
-The previous state of time caching (a value of 0 if it was off and -a value of 1 otherwise). -

-

Description
-The State Threads library has the ability to "cache" the time value that is -reported by the time(2) system call. If the time caching is enabled -by calling this function with a non-zero argument, then the result value -of time(2) will be stored and updated at most once per second. The -cached time can be retrieved by st_time(). -By default time caching is disabled. -You may enable or disable time caching at any time but generally -you enable it once (if desired) during program initialization.

-Note: There are some pathological cases (e.g., very heavy loads during -application benchmarking) when a single thread runs for a long time without -giving up control and the cached time value is not updated properly. If you -always need "real-time" time values, don't enable the time caching. -

-

-

- -

st_time()

- -Returns the value of time in seconds since 00:00:00 UTC, January 1, 1970. -

-

Syntax
- -
-#include <st.h>
-
-time_t st_time(void);
-
-

-

Parameters
-None. -

-

Returns
-The value of time in seconds since 00:00:00 UTC, January 1, 1970 as reported -by the time(2) system call. -

-

Description
-If the time caching was enabled by -st_timecache_set(), then this function returns -the cached result. Otherwise, it just calls time(2). -

-

-

- - -

I/O Functions

- -

-Most State Threads library I/O functions look like corresponding C library -functions with two exceptions: -

    -
  • They operate on file descriptor objects of type -st_netfd_t.
    • -
  • They take an additional argument of type -st_utime_t which represents an inactivity -timeout: if no I/O is possible during this amount of time, I/O functions -return an error code and set errno to ETIME. - -The boundary values ST_UTIME_NO_WAIT (0) and -ST_UTIME_NO_TIMEOUT (-1) for this argument indicate -that the thread should wait no time (function returns immediately) or -wait forever (never time out), respectively. - -Note that timeouts are measured since the -last context switch. -

- -Creates a new file descriptor object. -

-

Syntax
- -
-#include <st.h>
-
-st_netfd_t st_netfd_open(int osfd);
-
-

-

Parameters
-st_netfd_open() has the following parameters:

-osfd

- -Any open OS file descriptor; can be obtained from calls to -functions including, but not restricted to, pipe(2), socket(3), -socketpair(3), fcntl(2), dup(2), etc. - - -

-

Returns
-Upon successful completion, a new file descriptor object identifier is -returned. Otherwise, NULL is returned and errno is set -to indicate the error. -

-

Description
-This function creates a new file descriptor object of type -st_netfd_t.

- -Note: Among other things, this function sets a non-blocking -flag on the underlying OS file descriptor. You should not modify this -flag directly. Also, once an st_netfd_t -has been created with a given file descriptor, you should avoid -passing that descriptor to normal I/O or stdio functions. Since the -O_NONBLOCK flag is shared across dup(2), this applies to -dup()'ed file descriptors as well - for instance, if you pass -standard output or standard input to st_netfd_open(), then -you should use st_write() instead of write -or fprintf when writing to standard error as well - since all -three descriptors could point to the same terminal. If necessary, you -can still use write directly if you remember to check -errno for EAGAIN, but fprintf and other -stdio functions should be avoided completely because, at least on -Linux, the stdio library cannot be made to work reliably with -non-blocking files. (This only applies to file descriptors which are -passed to st_netfd_open() or st_netfd_open_socket(), or which are -related to such descriptors through dup(); other file -descriptors are untouched by State Threads.) -

-

-

- -

st_netfd_open_socket()

- -Creates a new file descriptor object from a socket. -

-

Syntax
- -
-#include <st.h>
-
-st_netfd_t st_netfd_open_socket(int osfd);
-
-

-

Parameters
-st_netfd_open_socket() has the following parameters:

-osfd

-An open OS file descriptor which is a socket initially obtained from a -socket(3) or socketpair(3) call. -

-

Returns
-Upon successful completion, a new file descriptor object identifier is -returned. Otherwise, NULL is returned and errno is set -to indicate the error. -

-

Description
-This function creates a new file descriptor object of type -st_netfd_t which represents an open end -point of network communication.

-Unlike the st_netfd_open() function which may be used -on OS file descriptors of any origin, st_netfd_open_socket() must -be used only on sockets. It is slightly more efficient than -st_netfd_open().

-Note: Among other things, this function sets a non-blocking flag -on the underlying OS socket. You should not modify this flag directly. -See st_netfd_open(). -

-

-

- -

st_netfd_free()

- -Frees a file descriptor object without closing the underlying OS file -descriptor. -

-

Syntax
- -
-#include <st.h>
-
-void st_netfd_free(st_netfd_t fd);
-
-

-

Parameters
-st_netfd_free() has the following parameters:

-fd

-A file descriptor object identifier (see -st_netfd_t). -

-

Returns
-Nothing. -

-

Description
-This function frees the memory and other resources identified by the -fd parameter without closing the underlying OS file descriptor. -Any non-NULL descriptor-specific data is destroyed by invoking -the specified destructor function (see st_netfd_setspecific()).

A thread should -not free file descriptor objects that are in use by other threads -because it may lead to unpredictable results (e.g., a freed file -descriptor may be reused without other threads knowing that). -

-

-

- -

st_netfd_close()

- -Closes a file descriptor. -

-

Syntax
- -
-#include <st.h>
-
-int st_netfd_close(st_netfd_t fd);
-
-

-

Parameters
-st_netfd_close() has the following parameters:

-fd

-A file descriptor object identifier (see -st_netfd_t). -

-

Returns
-Upon successful completion, a value of 0 is returned. -Otherwise, a value of -1 is returned and errno is set -to indicate the error. -

-

Description
-This function closes the underlying OS file descriptor, frees the memory and -other resources identified by the fd parameter. Any non-NULL -descriptor-specific data is destroyed by invoking the specified destructor -function (see st_netfd_setspecific()).

-A thread should not close file descriptor objects that are in use by other -threads because it may lead to unpredictable results (e.g., a closed -file descriptor may be reused without other threads knowing that). -

-

-

- -

st_netfd_fileno()

- -Returns an underlying OS file descriptor. -

-

-

Syntax
- -
-#include <st.h>
-
-void st_netfd_setspecific(st_netfd_t fd, void *value,
-                          void (*destructor)(void *));
-
-

-

Parameters
-st_netfd_setspecific() has the following parameters:

-fd

-A valid file descriptor object identifier (see -st_netfd_t). -

-value

-The per-descriptor private data, or more likely, a pointer to the data which -is being associated with the named file descriptor object. -

-destructor

-Specifies an optional destructor function for the private data associated -with fd. This function can be specified as NULL. -If value is not NULL, then this destructor function will -be called with value as an argument upon freeing the file descriptor -object (see st_netfd_free() and -st_netfd_close()). -

-

Returns
-Nothing. -

-

Description
-This function allows to associate any data with the specified file -descriptor object (network connection). If a non-NULL destructor -function is registered, it will be called at one of two times, as long as -the associated data is not NULL: -
    -
  • when private data is replaced by calling -st_netfd_setspecific() again -
  • upon freeing the file descriptor object (see -st_netfd_free() and -st_netfd_close()) -
-

-

-

- -

st_netfd_getspecific()

- -Retrieves the per-descriptor private data. -

-

Syntax
- -
-#include <st.h>
-
-void *st_netfd_getspecific(st_netfd_t fd);
-
-

-

Parameters
-st_netfd_getspecific() has the following parameters:

-fd

-A valid file descriptor object identifier (see -st_netfd_t). -

-

Returns
-The data associated with the named file descriptor object. If no data is -associated with fd, then NULL is returned. -

-

Description
-This function allows to retrieve the data that was associated with the -specified file descriptor object (see -st_netfd_setspecific()). -

-

-

- -

st_netfd_serialize_accept()

- -Serializes all subsequent accept(3) calls on a specified file -descriptor object. -

-

Syntax
- -
-#include <st.h>
-
-int st_netfd_serialize_accept(st_netfd_t fd);
-
-

-

Parameters
-st_netfd_serialize_accept() has the following parameters:

-fd

-A file descriptor object identifier (see -st_netfd_t) which has been successfully created -from a valid listening socket by st_netfd_open() or -st_netfd_open_socket(). -

-

Returns
-Upon successful completion, a value of 0 is returned. -Otherwise, a value of -1 is returned and errno is set -to indicate the error. -

-

Description
-On some platforms (e.g., Solaris 2.5 and possibly other SVR4 implementations) -accept(3) calls from different processes on -the same listening socket (see bind(3), listen(3)) must be -serialized. This function causes all subsequent accept(3) calls -made by st_accept() on the specified file descriptor -object to be serialized. -

-st_netfd_serialize_accept() must be called before -creating multiple server processes via fork(2). If the application -does not create multiple processes to accept network connections on -the same listening socket, there is no need to call this function. -

-Deciding whether or not to serialize accepts is tricky. On some -platforms (IRIX, Linux) it's not needed at all and -st_netfd_serialize_accept() is a no-op. On other platforms -it depends on the version of the OS (Solaris 2.6 doesn't need it but -earlier versions do). Serializing accepts does incur a slight -performance penalty so you want to enable it only if necessary. Read -your system's manual pages for accept(2) and select(2) -to see if accept serialization is necessary on your system. -

-st_netfd_serialize_accept() allocates resources that are -freed upon freeing of the specified file descriptor object (see -st_netfd_free() and -st_netfd_close()). -

-

-

- -

st_netfd_poll()

- -Waits for I/O on a single file descriptor object. -

-

Syntax
- -
-#include <st.h>
-
-int st_netfd_poll(st_netfd_t fd, int how, st_utime_t timeout);
-
-

-

Parameters
-st_netfd_poll() has the following parameters:

-fd

-A file descriptor object identifier (see -st_netfd_t). -

-how

-Specifies I/O events of interest. This parameter can be constructed by -OR-ing any combination of the following event flags which are defined -in the poll.h header file:

- - - - - -
POLLINfd is readable.
POLLOUTfd is is writable.
POLLPRIfd has an exception condition.
-

-timeout

-Amount of time in microseconds the call will block waiting for I/O -to become ready. This parameter is a variable of type -st_utime_t. If this time expires without any -I/O becoming ready, st_netfd_poll() returns an error and sets -errno to ETIME. -Note that timeouts are measured since the -last context switch. -

-

Returns
-If the named file descriptor object is ready for I/O within the specified -amount of time, a value of 0 is returned. Otherwise, a value -of -1 is returned and errno is set to indicate the error: -

- - - - -
EBADFThe underlying OS file descriptor is invalid. -
EINTRThe current thread was interrupted by -st_thread_interrupt().
ETIMEThe timeout occurred without any I/O -becoming ready.
-

-

Description
-This function returns as soon as I/O is ready on the named file -descriptor object or the specified amount of time expires. The -how parameter should be set to the I/O events (readable, -writable, exception, or some combination) that the caller is interested -in. If the value of timeout is ST_UTIME_NO_TIMEOUT -(-1), this function blocks until a requested I/O event occurs -or until the call is interrupted by st_thread_interrupt().

-Despite having an interface like poll(2), this function uses -the same event notification mechanism as the rest of the library. For -instance if an alternative event nofication mechanism was set using st_set_eventsys(), this function uses that -mechanism to check for events.

-Note: if kqueue(2) is used as an alternative event -notification mechanism (see st_set_eventsys()), the POLLPRI -event flag is not supported and st_netfd_poll() will return an error -if it's set (errno will be set to EINVAL). -

-

-

- -

st_accept()

- -Accepts a connection on a specified file descriptor object. -

-

Syntax
- -
-#include <st.h>
-
-st_netfd_t st_accept(st_netfd_t fd, struct sockaddr *addr, int *addrlen,
-                     st_utime_t timeout);
-
-

-

Parameters
-st_accept() has the following parameters:

-fd

-A file descriptor object identifier (see -st_netfd_t) representing the rendezvous socket -on which the caller is willing to accept new connections. This object has been -created from a valid listening socket by -st_netfd_open() or -st_netfd_open_socket().

-addr

-If this value is non-zero, it is a result parameter that is filled -in with the address of the connecting entity, as known to the communications -layer (see accept(3)).

-addrlen

-This parameter should initially contain the amount of space pointed to by -addr; on return it will contain the actual length (in bytes) of the -address returned (see accept(3)).

-timeout

-A value of type st_utime_t specifying the time -limit in microseconds for completion of the accept operation. -Note that timeouts are measured since the -last context switch. -

-

Returns
-Upon successful completion, a new file descriptor object identifier -representing the newly accepted connection is returned. Otherwise, -NULL is returned and errno is set to indicate the error. -Possible errno values are the same as set by the accept(3) -call with two exceptions:

- - - -
EINTRThe current thread was interrupted by -st_thread_interrupt().
ETIMEThe timeout occurred and no pending -connection was accepted.
-

-

Description
-This function accepts the first connection from the queue of pending -connections and creates a new file descriptor object for the newly -accepted connection. The rendezvous socket can still be used to accept -more connections.

-st_accept() blocks the calling thread until either a new connection -is successfully accepted or an error occurs. If no pending connection can -be accepted before the time limit, this function returns NULL -and sets errno to ETIME. -

-

-

- -

st_connect()

- -Initiates a connection on a specified file descriptor object. -

-

Syntax
- -
-#include <st.h>
-
-int st_connect(st_netfd_t fd, struct sockaddr *addr, int addrlen,
-               st_utime_t timeout);
-
-

-

Parameters
-st_connect() has the following parameters:

-fd

-A file descriptor object identifier (see -st_netfd_t) representing a socket.

-addr

-A pointer to the address of the peer to which the socket is to be connected. -

-addrlen

-This parameter specifies the amount of space pointed to by addr. -

-timeout

-A value of type st_utime_t specifying the time -limit in microseconds for completion of the connect operation. -Note that timeouts are measured since the -last context switch. -

-

Returns
-Upon successful completion, a value of 0 is returned. -Otherwise, a value of -1 is returned and errno is set -to indicate the error. Possible errno values are the same as set -by the connect(3) call with two exceptions:

- - - -
EINTRThe current thread was interrupted by -st_thread_interrupt().
ETIMEThe timeout occurred and connection setup -was not completed.
-

-

Description
-This function is usually invoked on a file descriptor object representing -a TCP socket. Upon completion it establishes a TCP connection to the peer. -If the underlying OS socket is not bound, it will be bound to an arbitrary -local address (see connect(3)).

-st_connect() blocks the calling thread until either the connection -is successfully established or an error occurs. If the connection setup -cannot complete before the specified time limit, this function fails with -errno set to ETIME. -

-

-

- -

Otherwise, a value of -1 is -returned and errno is set to indicate the error. -Possible errno values are the same as set by the read(2) -call with two exceptions:

- - - -
EINTRThe current thread was interrupted by -st_thread_interrupt().
ETIMEThe timeout occurred and no data was read. -
-

-

Description

-		    st_utime_t timeout);
-
-

-

Parameters
-st_writev_resid() has the following parameters:

-fd

-A file descriptor object identifier (see -st_netfd_t).

-iov

-A pointer to an array of iovec structures. -On entry, the iovecs identify the buffers holding the data to write. -On return, the incomplete iovecs. -This function modifies both the pointer and the array to which it points.

-iov_size

-A pointer to a number of iovec structures. -On entry, the number of iovec structures pointed to by *iov. -On return, the number of incomplete or unused iovec structures. -(A non-zero returned value means some but not all of the data was written.)

-timeout

-A value of type st_utime_t specifying the -inactivity timeout (in microseconds). -Note that timeouts are measured since the -last context switch. -

-

Returns
-On success, zero is returned, *iov_size is zero, and *iov -points to the first iovec after the end of the original array. -Otherwise, a value of -1 is returned, *iov_size is non-zero, -*iov points to the first incomplete iovec, and errno is set -to indicate the error. Possible errno values are the same as set -by the writev(2) call with two exceptions:

- - - -
EINTRThe current thread was interrupted by -st_thread_interrupt().
ETIMEThe timeout occurred. -
-

-All of the iovecs before *iov are modified such that -iov_base points to the end of the original buffer and -iov_len is zero. -

-

Description
-This function blocks the calling thread until all the data is written, -a timeout occurs, or the write operation fails. It differs from -st_writev() only in that it allows the caller to know how many bytes -were transferred before an error occurred. -

-

-

- -

st_recvfrom()

- -Receives bytes from a file descriptor object and stores the sending peer's -address. -

-

Syntax
- -
-#include <st.h>

-                int *fromlen, st_utime_t timeout);
-
-

-

Parameters
-st_recvfrom() has the following parameters:

-fd

-A file descriptor object identifier (see -st_netfd_t) representing a UDP socket.

-buf

-A pointer to a buffer to hold the data received.

-len

-The size of buf in bytes.

-from

-If this parameter is not a NULL pointer, the source address of the -message is filled in (see recvfrom(3)).

-fromlen

-This is a value-result parameter, initialized to the size of the buffer -associated with from, and modified on return to indicate the actual -size of the address stored there.

-timeout

-A value of type st_utime_t specifying the time -limit in microseconds for completion of the receive operation. -Note that timeouts are measured since the -last context switch. -

-

Returns
-On success a non-negative integer indicating the length of the received -message in bytes is returned. Otherwise, a value of -1 is returned -and errno is set to indicate the error. Possible errno -values are the same as set by the recvfrom(3) call with two -exceptions:

EINTRThe current thread was interrupted by -st_thread_interrupt().
ETIMEThe timeout occurred and no data was received. -
-

-

Description
-This function receives up to a specified number of bytes from the specified -file descriptor object representing a UDP socket.

-

-

Description
-This function sends bytes to a file descriptor object representing a UDP -socket. The operation is controlled by the msg parameter. -If no buffer space is available at the underlying OS socket to hold the -message to be transmitted, then st_sendmsg() blocks the calling -thread until the space becomes available, a timeout occurs, or an error -occurs. -

-

-

- -

st_open()

- -Opens a file for reading, writing, or both. -

-

Syntax
- -
-#include <st.h>
-
-st_netfd_t st_open(const char *path, int oflags, mode_t mode);
-
-

-

Parameters
-st_open() has the following parameters:

-path

-The pathname of the file to be opened.

-oflags

-File status flags. These are the same flags that are used by the -open(2) system call.

-mode

-Access permission bits of the file mode, if the file is created when -O_CREAT is set in oflags (see open(2)). -

-

Returns
-Upon successful completion, a new file descriptor object identifier is -returned. Otherwise, NULL is returned and errno is set -to indicate the error. -

-

Description
-This function creates a new file descriptor object of type -st_netfd_t for the file with the pathname -path. This object can be freed by -st_netfd_free() or -st_netfd_close().

-The primary purpose of this function is to open FIFOs (named pipes) or -other special files in order to create an end point of communication. -However, it can be used on regular files as well.

-Among other things, this function always sets a non-blocking flag on the -underlying OS file descriptor, so there is no need to include that flag in -oflags. -

-

-

- -

st_poll()

- -Detects when I/O is ready for a set of OS file descriptors. -

-

Syntax
- -
-#include <st.h>
-
-int st_poll(struct pollfd *pds, int npds, st_utime_t timeout);
-
-

-

Parameters
-st_poll() has the following parameters:

-pds

-A pointer to an array of pollfd structures (see poll(2)). -

-npds

-The number of elements in the pds array.

-timeout

-A value of type st_utime_t specifying the -amount of time in microseconds the call will block waiting for I/O -to become ready. If this time expires without any I/O becoming ready, -st_poll() returns zero. -Note that timeouts are measured since the -last context switch. -

-

Returns
-Upon successful completion, a non-negative value is returned. A positive -value indicates the total number of OS file descriptors in pds -that have events. A value of 0 indicates that the call timed out. -Upon failure, a value of -1 is returned and errno is set -to indicate the error:

- - -
EINTRThe current thread was interrupted by -st_thread_interrupt().
-

-If an alternative event notification mechanism has been set by -st_set_eventsys(), other values of -errno could be set upon failure as well. The values -depend on the specific mechanism in use. -

-

Description
-This function returns as soon as I/O is ready on one or more of the specified -OS file descriptors. A count of the number of ready descriptors is returned -unless a timeout occurs, in which case zero is returned.

-The pollfd structure is defined in the poll.h header file -and contains the following members:

-

-    int fd;             /* OS file descriptor */
-    short events;       /* requested events   */
-    short revents;      /* returned events    */
-
-The events field should be set to the I/O events (readable, -writable, exception, or some combination) that the caller is interested in. -On return, the revents field is set to indicate what kind of I/O -is ready on the respective descriptor.

-The events and revents fields are constructed by OR-ing -any combination of the following event flags (defined in poll.h): -

- - - - - - -
POLLINfd is readable.
POLLOUTfd is is writable.
POLLPRIfd has an exception condition.
POLLNVALfd is bad.
-

-The POLLNVAL flag is only valid in the revents field; -it is not used in the events field.

-Despite having an interface like poll(2), this function uses -the same event notification mechanism as the rest of the library. For -instance if an alternative event nofication mechanism was set using st_set_eventsys(), this function uses that -mechanism to check for events.

-Note that unlike the poll(2) call, this function has the -timeout parameter expressed in microseconds. If the value of -timeout is ST_UTIME_NO_TIMEOUT -(-1), this function blocks until a requested I/O -event occurs or until the call is interrupted by -st_thread_interrupt(). -

-Note: if kqueue(2) is used as an alternative event -notification mechanism (see st_set_eventsys()), the POLLPRI -event flag is not supported and st_poll() will return an error -if it's set (errno will be set to EINVAL). -

-

-

- - -

Program Structure

- -

-Generally, the following steps should be followed when writing an application -using the State Threads library: -

-

    -
  1. Configure the library by calling these pre-init functions, if desired. - -
    2. -

    -

  2. Initialize the library by calling st_init().
    3. -

    -

  3. Configure the library by calling these post-init functions, if desired. - -
    4. -

    -

  4. Create resources that will be shared among different processes: - create and bind listening sockets (see socket(3), - bind(3), listen(3), - st_netfd_open_socket(), and possibly - st_netfd_serialize_accept()), - create shared memory segments, inter-process communication (IPC) - channels and synchronization primitives (if any).
    5. -

    -

  5. Create several processes via fork(2). The parent process should - either exit or become a "watchdog" (e.g., it starts a new process when - an existing one crashes, does a cleanup upon application termination, - etc.).
    6. -

    -

  6. In each child process create a pool of threads (see - st_thread_create()) to handle user - connections. Each thread in the pool may accept client connections - (st_accept()), connect to other servers - (st_connect()), perform various network I/O - (st_read(), st_write(), etc.).
    7. -
-

-Note that only State Threads library I/O functions should -be used for a network I/O: any other I/O calls may block the calling process -indefinitely. For example, standard I/O functions (fgets(3), -fread(3), fwrite(3), fprintf(3), etc.) call -read(2) and write(2) directly and therefore should not be -used on sockets or pipes. -

-Also note that for short timeouts to work the program -should do context switches (for example by calling -st_usleep()) on a regular basis. -

-

-

- - -

List of Blocking Functions

State Threads for Internet Applications

-

Introduction

-

-State Threads is an application library which provides a -foundation for writing fast and highly scalable Internet Applications -on UNIX-like platforms. It combines the simplicity of the multithreaded -programming paradigm, in which one thread supports each simultaneous -connection, with the performance and scalability of an event-driven -state machine architecture.

- -

1. Definitions

-

- -

1.1 Internet Applications

- -

-An Internet Application (IA) is either a server or client network -application that accepts connections from clients and may or may not -connect to servers. In an IA the arrival or departure of network data -often controls processing (that is, IA is a data-driven application). -For each connection, an IA does some finite amount of work -involving data exchange with its peer, where its peer may be either -a client or a server. -The typical transaction steps of an IA are to accept a connection, -read a request, do some finite and predictable amount of work to -process the request, then write a response to the peer that sent the -request. One example of an IA is a Web server; -the most general example of an IA is a proxy server, because it both -accepts connections from clients and connects to other servers.

-

-We assume that the performance of an IA is constrained by available CPU -cycles rather than network bandwidth or disk I/O (that is, CPU -is a bottleneck resource). -

- - -

1.2 Performance and Scalability

- -

-The performance of an IA is usually evaluated as its -throughput measured in transactions per second or bytes per second (one -can be converted to the other, given the average transaction size). There are -several benchmarks that can be used to measure throughput of Web serving -applications for specific workloads (such as -SPECweb96, -WebStone, -WebBench). -Although there is no common definition for scalability, in general it -expresses the ability of an application to sustain its performance when some -external condition changes. For IAs this external condition is either the -number of clients (also known as "users," "simultaneous connections," or "load -generators") or the underlying hardware system size (number of CPUs, memory -size, and so on). Thus there are two types of scalability: load -scalability and system scalability, respectively. -

-The figure below shows how the throughput of an idealized IA changes with -the increasing number of clients (solid blue line). Initially the throughput -grows linearly (the slope represents the maximal throughput that one client -can provide). Within this initial range, the IA is underutilized and CPUs are -partially idle. Further increase in the number of clients leads to a system -saturation, and the throughput gradually stops growing as all CPUs become fully -utilized. After that point, the throughput stays flat because there are no -more CPU cycles available. -In the real world, however, each simultaneous connection -consumes some computational and memory resources, even when idle, and this -overhead grows with the number of clients. Therefore, the throughput of the -real world IA starts dropping after some point (dashed blue line in the figure -below). The rate at which the throughput drops depends, among other things, on -application design. -

-We say that an application has a good load scalability if it can -sustain its throughput over a wide range of loads. -Interestingly, the SPECweb99 -benchmark somewhat reflects the Web server's load scalability because it -measures the number of clients (load generators) given a mandatory minimal -throughput per client (that is, it measures the server's capacity). -This is unlike SPECweb96 and -other benchmarks that use the throughput as their main metric (see the figure -below). -

-

Figure: Throughput vs. Number of clients -
-

-System scalability is the ability of an application to sustain its -performance per hardware unit (such as a CPU) with the increasing number of -these units. In other words, good system scalability means that doubling the -number of processors will roughly double the application's throughput (dashed -green line). We assume here that the underlying operating system also scales -well. Good system scalability allows you to initially run an application on -the smallest system possible, while retaining the ability to move that -application to a larger system if necessary, without excessive effort or -expense. That is, an application need not be rewritten or even undergo a -major porting effort when changing system size. -

-Although scalability and performance are more important in the case of server -IAs, they should also be considered for some client applications (such as -benchmark load generators). -

- - -

1.3 Concurrency

- -

-Concurrency reflects the parallelism in a system. The two unrelated types -are virtual concurrency and real concurrency. -

    -
  • Virtual (or apparent) concurrency is the number of simultaneous -connections that a system supports. -

    -
  • Real concurrency is the number of hardware devices, including -CPUs, network cards, and disks, that actually allow a system to perform -tasks in parallel. -
-

-An IA must provide virtual concurrency in order to serve many users -simultaneously. -To achieve maximum performance and scalability in doing so, the number of -programming entities than an IA creates to be scheduled by the OS kernel -should be -kept close to (within an order of magnitude of) the real concurrency found on -the system. These programming entities scheduled by the kernel are known as -kernel execution vehicles. Examples of kernel execution vehicles -include Solaris lightweight processes and IRIX kernel threads. -In other words, the number of kernel execution vehicles should be dictated by -the system size and not by the number of simultaneous connections. -

- -

2. Existing Architectures

-

-There are a few different architectures that are commonly used by IAs. -These include the Multi-Process, -Multi-Threaded, and Event-Driven State Machine -architectures. -

- -

2.1 Multi-Process Architecture

- -

-In the Multi-Process (MP) architecture, an individual process is -dedicated to each simultaneous connection. -A process performs all of a transaction's initialization steps -and services a connection completely before moving on to service -a new connection. -

-User sessions in IAs are relatively independent; therefore, no -synchronization between processes handling different connections is -necessary. Because each process has its own private address space, -this architecture is very robust. If a process serving one of the connections -crashes, the other sessions will not be affected. However, to serve many -concurrent connections, an equal number of processes must be employed. -Because processes are kernel entities (and are in fact the heaviest ones), -the number of kernel entities will be at least as large as the number of -concurrent sessions. On most systems, good performance will not be achieved -when more than a few hundred processes are created because of the high -context-switching overhead. In other words, MP applications have poor load -scalability. -

-On the other hand, MP applications have very good system scalability, because -no resources are shared among different processes and there is no -synchronization overhead. -

-The Apache Web Server 1.x ([Reference 1]) uses the MP -architecture on UNIX systems. -

- -

2.2 Multi-Threaded Architecture

- -

-In the Multi-Threaded (MT) architecture, multiple independent threads -of control are employed within a single shared address space. Like a -process in the MP architecture, each thread performs all of a -transaction's initialization steps and services a connection completely -before moving on to service a new connection. -

-Many modern UNIX operating systems implement a many-to-few model when -mapping user-level threads to kernel entities. In this model, an -arbitrarily large number of user-level threads is multiplexed onto a -lesser number of kernel execution vehicles. Kernel execution -vehicles are also known as virtual processors. Whenever a user-level -thread makes a blocking system call, the kernel execution vehicle it is using -will become blocked in the kernel. If there are no other non-blocked kernel -execution vehicles and there are other runnable user-level threads, a new -kernel execution vehicle will be created automatically. This prevents the -application from blocking when it can continue to make useful forward -progress. -

-Because IAs are by nature network I/O driven, all concurrent sessions block on -network I/O at various points. As a result, the number of virtual processors -created in the kernel grows close to the number of user-level threads -(or simultaneous connections). When this occurs, the many-to-few model -effectively degenerates to a one-to-one model. Again, like in -the MP architecture, the number of kernel execution vehicles is dictated by -the number of simultaneous connections rather than by number of CPUs. This -reduces an application's load scalability. However, because kernel threads -(lightweight processes) use fewer resources and are more light-weight than -traditional UNIX processes, an MT application should scale better with load -than an MP application. -

-Unexpectedly, the small number of virtual processors sharing the same address -space in the MT architecture destroys an application's system scalability -because of contention among the threads on various locks. Even if an -application itself is carefully -optimized to avoid lock contention around its own global data (a non-trivial -task), there are still standard library functions and system calls -that use common resources hidden from the application. For example, -on many platforms thread safety of memory allocation routines -(malloc(3), free(3), and so on) is achieved by using a single -global lock. Another example is a per-process file descriptor table. -This common resource table is shared by all kernel execution vehicles within -the same process and must be protected when one modifies it via -certain system calls (such as open(2), close(2), and so on). -In addition to that, maintaining the caches coherent -among CPUs on multiprocessor systems hurts performance when different threads -running on different CPUs modify data items on the same cache line. -

-In order to improve load scalability, some applications employ a different -type of MT architecture: they create one or more thread(s) per task -rather than one thread per connection. For example, one small group -of threads may be responsible for accepting client connections, another -for request processing, and yet another for serving responses. The main -advantage of this architecture is that it eliminates the tight coupling -between the number of threads and number of simultaneous connections. However, -in this architecture, different task-specific thread groups must share common -work queues that must be protected by mutual exclusion locks (a typical -producer-consumer problem). This adds synchronization overhead that causes an -application to perform badly on multiprocessor systems. In other words, in -this architecture, the application's system scalability is sacrificed for the -sake of load scalability. -

-Of course, the usual nightmares of threaded programming, including data -corruption, deadlocks, and race conditions, also make MT architecture (in any -form) non-simplistic to use. -

- - -

2.3 Event-Driven State Machine Architecture

- -

-In the Event-Driven State Machine (EDSM) architecture, a single process -is employed to concurrently process multiple connections. The basics of this -architecture are described in Comer and Stevens -[Reference 2]. -The EDSM architecture performs one basic data-driven step associated with -a particular connection at a time, thus multiplexing many concurrent -connections. The process operates as a state machine that receives an event -and then reacts to it. -

-In the idle state the EDSM calls select(2) or poll(2) to -wait for network I/O events. When a particular file descriptor is ready for -I/O, the EDSM completes the corresponding basic step (usually by invoking a -handler function) and starts the next one. This architecture uses -non-blocking system calls to perform asynchronous network I/O operations. -For more details on non-blocking I/O see Stevens -[Reference 3]. -

-To take advantage of hardware parallelism (real concurrency), multiple -identical processes may be created. This is called Symmetric Multi-Process -EDSM and is used, for example, in the Zeus Web Server -([Reference 4]). To more efficiently multiplex disk I/O, -special "helper" processes may be created. This is called Asymmetric -Multi-Process EDSM and was proposed for Web servers by Druschel -and others [Reference 5]. -

-EDSM is probably the most scalable architecture for IAs. -Because the number of simultaneous connections (virtual concurrency) is -completely decoupled from the number of kernel execution vehicles (processes), -this architecture has very good load scalability. It requires only minimal -user-level resources to create and maintain additional connection. -

-Like MP applications, Multi-Process EDSM has very good system scalability -because no resources are shared among different processes and there is no -synchronization overhead. -

-Unfortunately, the EDSM architecture is monolithic rather than based on the -concept of threads, so new applications generally need to be implemented from -the ground up. In effect, the EDSM architecture simulates threads and their -stacks the hard way. -

- - -

3. State Threads Library

- -

-The State Threads library combines the advantages of all of the above -architectures. The interface preserves the programming simplicity of thread -abstraction, allowing each simultaneous connection to be treated as a separate -thread of execution within a single process. The underlying implementation is -close to the EDSM architecture as the state of each particular concurrent -session is saved in a separate memory segment. -

- -

3.1 State Changes and Scheduling

-

-The state of each concurrent session includes its stack environment -(stack pointer, program counter, CPU registers) and its stack. Conceptually, -a thread context switch can be viewed as a process changing its state. There -are no kernel entities involved other than processes. -Unlike other general-purpose threading libraries, the State Threads library -is fully deterministic. The thread context switch (process state change) can -only happen in a well-known set of functions (at I/O points or at explicit -synchronization points). As a result, process-specific global data does not -have to be protected by mutual exclusion locks in most cases. The entire -application is free to use all the static variables and non-reentrant library -functions it wants, greatly simplifying programming and debugging while -increasing performance. This is somewhat similar to a co-routine model -(co-operatively multitasked threads), except that no explicit yield is needed --- -sooner or later, a thread performs a blocking I/O operation and thus surrenders -control. All threads of execution (simultaneous connections) have the -same priority, so scheduling is non-preemptive, like in the EDSM architecture. -Because IAs are data-driven (processing is limited by the size of network -buffers and data arrival rates), scheduling is non-time-slicing. -

-Only two types of external events are handled by the library's -scheduler, because only these events can be detected by -select(2) or poll(2): I/O events (a file descriptor is ready -for I/O) and time events -(some timeout has expired). However, other types of events (such as -a signal sent to a process) can also be handled by converting them to I/O -events. For example, a signal handling function can perform a write to a pipe -(write(2) is reentrant/asynchronous-safe), thus converting a signal -event to an I/O event. -

-To take advantage of hardware parallelism, as in the EDSM architecture, -multiple processes can be created in either a symmetric or asymmetric manner. -Process management is not in the library's scope but instead is left up to the -application. -

-There are several general-purpose threading libraries that implement a -many-to-one model (many user-level threads to one kernel execution -vehicle), using the same basic techniques as the State Threads library -(non-blocking I/O, event-driven scheduler, and so on). For an example, see GNU -Portable Threads ([Reference 6]). Because they are -general-purpose, these libraries have different objectives than the State -Threads library. The State Threads library is not a general-purpose -threading library, -but rather an application library that targets only certain types of -applications (IAs) in order to achieve the highest possible performance and -scalability for those applications. -

3.2 Scalability

-

-State threads are very lightweight user-level entities, and therefore creating -and maintaining user connections requires minimal resources. An application -using the State Threads library scales very well with the increasing number -of connections. -

-On multiprocessor systems an application should create multiple processes -to take advantage of hardware parallelism. Using multiple separate processes -is the only way to achieve the highest possible system scalability. -This is because duplicating per-process resources is the only way to avoid -significant synchronization overhead on multiprocessor systems. Creating -separate UNIX processes naturally offers resource duplication. Again, -as in the EDSM architecture, there is no connection between the number of -simultaneous connections (which may be very large and changes within a wide -range) and the number of kernel entities (which is usually small and constant). -In other words, the State Threads library makes it possible to multiplex a -large number of simultaneous connections onto a much smaller number of -separate processes, thus allowing an application to scale well with both -the load and system size. -

- -

3.3 Performance

-

-Performance is one of the library's main objectives. The State Threads -library is implemented to minimize the number of system calls and -to make thread creation and context switching as fast as possible. -For example, per-thread signal mask does not exist (unlike -POSIX threads), so there is no need to save and restore a process's -signal mask on every thread context switch. This eliminates two system -calls per context switch. Signal events can be handled much more -efficiently by converting them to I/O events (see above). -

- -

3.4 Portability

-

-The library uses the same general, underlying concepts as the EDSM -architecture, including non-blocking I/O, file descriptors, and -I/O multiplexing. These concepts are available in some form on most -UNIX platforms, making the library very portable across many -flavors of UNIX. There are only a few platform-dependent sections in the -source. -

- -

3.5 State Threads and NSPR

-

-The State Threads library is a derivative of the Netscape Portable -Runtime library (NSPR) [Reference 7]. The primary goal of -NSPR is to provide a platform-independent layer for system facilities, -where system facilities include threads, thread synchronization, and I/O. -Performance and scalability are not the main concern of NSPR. The -State Threads library addresses performance and scalability while -remaining much smaller than NSPR. It is contained in 8 source files -as opposed to more than 400, but provides all the functionality that -is needed to write efficient IAs on UNIX-like platforms. -

Conclusion

-

-State Threads is an application library which provides a foundation for -writing Internet Applications. To summarize, it has the -following advantages: -

-

    -
  • It allows the design of fast and highly scalable applications. An -application will scale well with both load and number of CPUs. -

    -

  • It greatly simplifies application programming and debugging because, as a -rule, no mutual exclusion locking is necessary and the entire application is -free to use static variables and non-reentrant library functions. -
-

-The library's main limitation: -

-

    -
  • All I/O operations on sockets must use the State Thread library's I/O -functions because only those functions perform thread scheduling and prevent -the application's processes from blocking. -

This improves performance when there is a large number -of sleeping threads, since insertion into a heap takes O(log N) time -while insertion into a sorted list takes O(N) time. For example, in -one test 1000 threads were created, each thread called st_usleep() -with a random time interval, and then all the threads where -immediately interrupted and joined before the sleeps had a chance to -finish. The whole process was repeated 1000 times, for a total of a -million sleep queue insertions and removals. With the old list-based -sleep queue, this test took 100 seconds; now it takes only 12 seconds. - -Heap data structures are typically based on dynamically resized -arrays. However, since the existing ST code base was very nicely -structured around linking the thread objects into pointer-based lists -without the need for any auxiliary data structures, implementing the -heap using a similar nodes-and-pointers based approach seemed more -appropriate for ST than introducing a separate array. - -Thus, the new ST timeout heap works by organizing the existing -_st_thread_t objects in a balanced binary tree, just as they were -previously organized into a doubly-linked, sorted list. The global -_ST_SLEEPQ variable, formerly a linked list head, is now simply a -pointer to the root of this tree, and the root node of the tree is the -thread with the earliest timeout. Each thread object has two child -pointers, "left" and "right", pointing to threads with later timeouts. - -Each node in the tree is numbered with an integer index, corresponding -to the array index in an array-based heap, and the tree is kept fully -balanced and left-adjusted at all times. In other words, the tree -consists of any number of fully populated top levels, followed by a -single bottom level which may be partially populated, such that any -existing nodes form a contiguous block to the left and the spaces for -missing nodes form a contiguous block to the right. For example, if -there are nine threads waiting for a timeout, they are numbered and -arranged in a tree exactly as follows: - - 1 - / \ - 2 3 - / \ / \ - 4 5 6 7 - / \ - 8 9 - -Each node has either no children, only a left child, or both a left -and a right child. Children always time out later than their parents -(this is called the "heap invariant"), but when a node has two -children, their mutual order is unspecified - the left child may time -out before or after the right child. If a node is numbered N, its -left child is numbered 2N, and its right child is numbered 2N+1. - -There is no pointer from a child to its parent; all pointers point -downward. Additions and deletions both work by starting at the root -and traversing the tree towards the leaves, going left or right -according to the binary digits forming the index of the destination -node. As nodes are added or deleted, existing nodes are rearranged to -maintain the heap invariant. diff --git a/trunk/3rdparty/st-srs/event.c b/trunk/3rdparty/st-srs/event.c deleted file mode 100644 index 142882a51e..0000000000 --- a/trunk/3rdparty/st-srs/event.c +++ /dev/null @@ -1,1413 +0,0 @@ -/* - * The contents of this file are subject to the Mozilla Public - * License Version 1.1 (the "License"); you may not use this file - * except in compliance with the License.

Each virtual processor manages - * its own independent set of state threads (STs), the number of which varies - * with load against the server. Each state thread listens to exactly one - * listening socket. The initial process becomes the watchdog, waiting for - * children (VPs) to die or for a signal requesting termination or restart. - * Upon receiving a restart signal (SIGHUP), all VPs close and then reopen - * log files and reload configuration. All currently active connections remain - * active. It is assumed that new configuration affects only request - * processing and not the general server parameters such as number of VPs, - * thread limits, bind addresses, etc. Those are specified as command line - * arguments, so the server has to be stopped and then started again in order - * to change them. - * - * Each state thread loops processing connections from a single listening - * socket. Only one ST runs on a VP at a time, and VPs do not share memory, - * so no mutual exclusion locking is necessary on any data, and the entire - * server is free to use all the static variables and non-reentrant library - * functions it wants, greatly simplifying programming and debugging and - * increasing performance (for example, it is safe to ++ and -- all global - * counters or call inet_ntoa(3) without any mutexes).

Its usefulness is limited to cases where -random access to a file is required and where starvation of other threads -is unacceptable. - -The particular application which motivated this implementation was a UDP -file transfer protocol. Because the OS does very little buffering of UDP -traffic it is important that UDP transmission threads are not starved for -periods of time which are long relative to the interval required to -maintain a steady send rate. - -Licensed under the same dual MPL/GPL as core State Threads. - -======================================================================== - -stx_dns -------- - -Documentation coming. - -======================================================================== diff --git a/trunk/3rdparty/st-srs/extensions/common.h b/trunk/3rdparty/st-srs/extensions/common.h deleted file mode 100644 index f6298ba09e..0000000000 --- a/trunk/3rdparty/st-srs/extensions/common.h +++ /dev/null @@ -1,77 +0,0 @@ -#ifndef _STX_COMMON_H_ -#define _STX_COMMON_H_ - -#include -#include - - -#define STX_BEGIN_MACRO { -#define STX_END_MACRO } - - -/***************************************** - * Circular linked list definitions - */ - -typedef struct _stx_clist { - struct _stx_clist *next; - struct _stx_clist *prev; -} stx_clist_t; - -/* Insert element "_e" into the list, before "_l" */ -#define STX_CLIST_INSERT_BEFORE(_e,_l) \ - STX_BEGIN_MACRO \ - (_e)->next = (_l); \ - (_e)->prev = (_l)->prev; \ - (_l)->prev->next = (_e); \ - (_l)->prev = (_e); \ - STX_END_MACRO - -/* Insert element "_e" into the list, after "_l" */ -#define STX_CLIST_INSERT_AFTER(_e,_l) \ - STX_BEGIN_MACRO \ - (_e)->next = (_l)->next; \ - (_e)->prev = (_l); \ - (_l)->next->prev = (_e); \ - (_l)->next = (_e); \ - STX_END_MACRO - -/* Append an element "_e" to the end of the list "_l" */ -#define STX_CLIST_APPEND_LINK(_e,_l) STX_CLIST_INSERT_BEFORE(_e,_l) - -/* Remove the element "_e" from it's circular list */ -#define STX_CLIST_REMOVE_LINK(_e) \ - STX_BEGIN_MACRO \ - (_e)->prev->next = (_e)->next; \ - (_e)->next->prev = (_e)->prev; \ - STX_END_MACRO - -/* Return the head/tail of the list */ -#define STX_CLIST_HEAD(_l) (_l)->next -#define STX_CLIST_TAIL(_l) (_l)->prev - -/* Return non-zero if the given circular list "_l" is empty, */ -/* zero if the circular list is not empty */ -#define STX_CLIST_IS_EMPTY(_l) \ - ((_l)->next == (_l)) - -/* Initialize a circular list */ -#define STX_CLIST_INIT_CLIST(_l) \ - STX_BEGIN_MACRO \ - (_l)->next = (_l); \ - (_l)->prev = (_l); \ - STX_END_MACRO - - -/***************************************** - * Useful macros - */ - -#ifndef offsetof -#define offsetof(type, identifier) ((size_t)&(((type *)0)->identifier)) -#endif - -#define STX_MIN(a, b) (((a) < (b)) ?

This has been useful in debugging deadlocks, etc... -Our usage model is that the SIGUSR2 handler calls the new -_st_print_thread_stacks function, which dumps the stack for all -threads. A convenient feature is that for thread stacks that are the -same (which is common for application with a lot of worker threads -waiting for work), only one stack trace is printed, along with a -count of how many threads have that same stack. - -I use the glibc backtrace function to get the backtrace, and then use -popen to execute addr2line and convert memory addresses to file -names, function names, and line numbers. If glibc isn't available, -_st_print_thread_stacks just prints a warning.

The only +way to see thread's stack platform-independently is to actually jump to +the saved context. That's what the _st_iterate_threads() function does. +Do the following to iterate over all threads: + +- set the _st_iterate_threads_flag to 1 in debugger +- set breakpoint at the _st_show_thread_stack() function + (which does nothing) +- call the _st_iterate_threads() function which jumps to the + next thread +- at each break you can explore thread's stack +- continue +- when iteration is complete, you return to the original + point (you can see thread id and a message as arguments of + the _st_show_thread_stack() function). + +You can call _st_iterate_threads() in three ways: + +- Insert it into your source code at the point you want to + go over threads. +- Just run application and this function will be called at + the first context switch. +- Call it directly from the debugger at any point. + +This works with gdb and dbx. + +Example using gdb: + +(gdb) set _st_iterate_threads_flag = 1 +(gdb) b _st_show_thread_stack +... +(gdb) call _st_iterate_threads() +... +(gdb) bt +... +(gdb) c +... +(gdb) bt +... +(gdb) c +... +and so on... + +_st_iterate_threads_flag will be set to 0 automatically +after iteration is over or you can set it to 0 at any time +to stop iteration. + +Sometimes gdb complains about SIGSEGV when you call a function +directly at gdb command-line.

Terpstra's Darwin (MacOS X) port. + +o Support for many CPU architectures under Linux and *BSD. + +o Renamed private typedefs so they don't conflict with public ones any + more. + +o common.h now includes public.h for strict prototyping. + +o Joshua Levy's recommendation to make st_connect() and st_sendto() + accept const struct sockaddr pointers, as the originals do. + +o Clarified the documentation regarding blocking vs. non-blocking I/O. + +o Cygwin support. + +o Created the extensions directory. + +o Fixed warnings from ia64asm.S. + + +Changes from 1.2 to 1.3. +------------------------ +o Added st_read_resid() and st_write_resid() to allow the caller to know + how much data was transferred before an error occurred. Updated + documentation. + +o Updated project link, copyrights, and documentation regarding + timeouts. Added comment to st_connect(). + +o Optimized the _st_add_sleep_q() function in sched.c. Now we walk the + sleep queue *backward* when inserting a thread into it. When you + have lots (hundreds) of threads and several timeout values, it takes + a while to insert a thread at the appropriate point in the sleep + queue. The idea is that often this appropriate point is closer to + the end of the queue rather than the beginning. Measurements show + performance improves with this change. In any case this change + should do no harm. + +o Added a hint of when to define USE_POLL and when not to, to the + Makefile. + +o Added debugging support (files common.h and sched.c). See above. + +o Decreased the number of reallocations of _ST_POLLFDS in sched.c. + Inspired by Lev Walkin. + +o Fixed st_usleep(-1) and st_sleep(-1), and added a warning to the + documentation about too-large timeouts. + +o Linux/*BSD Alpha port. + +o Wesley W. Terpstra modernized the build process: + - properly build relocatable libraries under bsd and linux + - use library versioning + - added rpm spec file + - added debian/ files + See above for build instructions. + + +Changes from 1.1 to 1.2. +------------------------ +o Added st_randomize_stacks(). + +o Added a patch contributed by Sascha Schumann. + + +Changes from 1.0 to 1.1. +------------------------ +o Relicensed under dual MPL-GPL. + +o OpenBSD port. + +o Compile-time option to use poll() instead of select() for + event polling (see Makefile). + This is useful if you want to support a large number of open + file descriptors (larger than FD_SETSIZE) within a single + process. + +o Linux IA-64 port. + Two issues make IA-64 different from other platforms: + + - Besides the traditional call stack in memory, IA-64 uses the + general register stack. Thus each thread needs a backing store + for the register stack in addition to the memory stack. + + - Current implementation of setjmp()/longjmp() can not be used + for thread context-switching since it assumes that only one + register stack exists. Using special assembly functions for + context-switching is unavoidable. + +o Thread stack capping on IRIX. + This allows some profiling tools (such as SpeedShop) to know when + to stop unwinding the stack. Without this libexc, used by SpeedShop, + traces right off the stack and crashes. + +o Miscellaneous documentation additions. + + +COPYRIGHTS + +Portions created by SGI are Copyright (C) 2000 Silicon Graphics, Inc. +All Rights Reserved. diff --git a/trunk/3rdparty/st-srs/README.md b/trunk/3rdparty/st-srs/README.md new file mode 100644 index 0000000000..60fc1a6518 --- /dev/null +++ b/trunk/3rdparty/st-srs/README.md @@ -0,0 +1,88 @@ +# state-threads + +![](http://ossrs.net:8000/gif/v1/sls.gif?site=github.com&path=/srs/srsst) +[![](https://cloud.githubusercontent.com/assets/2777660/22814959/c51cbe72-ef92-11e6-81cc-32b657b285d5.png)](https://github.com/ossrs/srs/wiki/v1_CN_Contact#wechat) + +Fork from http://sourceforge.net/projects/state-threads, patched for [SRS](https://github.com/ossrs/srs/tree/2.0release). + +> See: https://github.com/ossrs/state-threads/blob/srs/README + +For original ST without any changes, checkout the [ST master branch](https://github.com/ossrs/state-threads/tree/master). + +## Branch SRS + +The branch [srs](https://github.com/ossrs/state-threads/tree/srs) will be patched the following patches: + +- [x] Patch [st.arm.patch](https://github.com/ossrs/srs/blob/2.0release/trunk/3rdparty/patches/1.st.arm.patch), for ARM. +- [x] Patch [st.osx.kqueue.patch](https://github.com/ossrs/srs/blob/2.0release/trunk/3rdparty/patches/3.st.osx.kqueue.patch), for osx. +- [x] Patch [st.disable.examples.patch](https://github.com/ossrs/srs/blob/2.0release/trunk/3rdparty/patches/4.st.disable.examples.patch), for ubuntu. +- [x] [Refine TAB of code](https://github.com/ossrs/state-threads/compare/c2001d30ca58f55d72a6cc6b9b6c70391eaf14db...d2101b26988b0e0db0aabc53ddf452068c1e2cbc). +- [x] Merge from [michaeltalyansky](https://github.com/michaeltalyansky/state-threads) and [xzh3836598](https://github.com/ossrs/state-threads/commit/9a17dec8f9c2814d93761665df7c5575a4d2d8a3), support [ARM](https://github.com/ossrs/state-threads/issues/1). +- [x] Merge from [toffaletti](https://github.com/toffaletti/state-threads), support [valgrind](https://github.com/ossrs/state-threads/issues/2) for ST. +- [x] Patch [st.osx10.14.build.patch](https://github.com/ossrs/srs/blob/2.0release/trunk/3rdparty/patches/6.st.osx10.14.build.patch), for osx 10.14 build. +- [x] Support macro `MD_ST_NO_ASM` to disable ASM, [#8](https://github.com/ossrs/state-threads/issues/8). +- [x] Merge patch [srs#1282](https://github.com/ossrs/srs/issues/1282#issuecomment-445539513) to support aarch64, [#9](https://github.com/ossrs/state-threads/issues/9). + +## Docs + +* Introduction: http://ossrs.github.io/state-threads/docs/st.html +* API reference: http://ossrs.github.io/state-threads/docs/reference.html +* Programming notes: http://ossrs.github.io/state-threads/docs/notes.html + +## Usage + +Get code: + +``` +git clone https://github.com/ossrs/state-threads.git st-1.9 && +git checkout -b srs origin/srs +``` + +For Linux: + +``` +make linux-debug EXTRA_CFLAGS="-DMD_HAVE_EPOLL" +``` + +For OSX: + +``` +make darwin-debug EXTRA_CFLAGS="-DMD_HAVE_KQUEUE" +``` + +Linux with valgrind: + +``` +make linux-debug EXTRA_CFLAGS="-DMD_VALGRIND" +``` + +> Remark: User must install valgrind, for instance, in centos6 `sudo yum install -y valgrind valgrind-devel`. + +Linux with valgrind and epoll: + +``` +make linux-debug EXTRA_CFLAGS="-DMD_HAVE_EPOLL -DMD_VALGRIND" +``` + +For OSX, user must specifies the valgrind header files: + +``` +make darwin-debug EXTRA_CFLAGS="-DMD_HAVE_KQUEUE -DMD_VALGRIND -I/usr/local/include" +``` + +> Remark: Latest OSX does not support ST, please use docker to run ST. + +## Valgrind + +How to debug with gdb under valgrind, read [valgrind manual](http://valgrind.org/docs/manual/manual-core-adv.html#manual-core-adv.gdbserver-simple). + +About startup parameters, read [valgrind cli](http://valgrind.org/docs/manual/mc-manual.html#mc-manual.options). + +Important cli options: + +1. `--undef-value-errors= [default: yes]`, Controls whether Memcheck reports uses of undefined value errors.

Programming Notes

+

+ +

+ +

+

+

+ +

Porting

+The State Threads library uses OS concepts that are available in some +form on most UNIX platforms, making the library very portable across +many flavors of UNIX. However, there are several parts of the library +that rely on platform-specific features. Here is the list of such parts: +

+

    +
  • Thread context initialization: Two ingredients of the +jmp_buf +data structure (the program counter and the stack pointer) have to be +manually set in the thread creation routine. The jmp_buf data +structure is defined in the setjmp.h header file and differs from +platform to platform. Usually the program counter is a structure member +with PC in the name and the stack pointer is a structure member +with SP in the name. One can also look in the +Netscape's NSPR library source +which already has this code for many UNIX-like platforms +(mozilla/nsprpub/pr/include/md/*.h files). +

    +Note that on some BSD-derived platforms _setjmp(3)/_longjmp(3) +calls should be used instead of setjmp(3)/longjmp(3) (that is +the calls that manipulate only the stack and registers and do not +save and restore the process's signal mask).

    • +

    +Starting with glibc 2.4 on Linux the opacity of the jmp_buf data +structure is enforced by setjmp(3)/longjmp(3) so the +jmp_buf ingredients cannot be accessed directly anymore (unless +special environmental variable LD_POINTER_GUARD is set before application +execution). To avoid dependency on custom environment, the State Threads +library provides setjmp/longjmp replacement functions for +all Intel CPU architectures. Other CPU architectures can also be easily +supported (the setjmp/longjmp source code is widely available for +many CPU architectures). +

    +

  • High resolution time function: Some platforms (IRIX, Solaris) +provide a high resolution time function based on the free running hardware +counter. This function returns the time counted since some arbitrary +moment in the past (usually machine power up time). It is not correlated in +any way to the time of day, and thus is not subject to resetting, +drifting, etc. This type of time is ideal for tasks where cheap, accurate +interval timing is required. If such a function is not available on a +particular platform, the gettimeofday(3) function can be used +(though on some platforms it involves a system call). +

    +

  • The stack growth direction: The library needs to know whether the +stack grows toward lower (down) or higher (up) memory addresses. +One can write a simple test program that detects the stack growth direction +on a particular platform.
    • +

    +

  • Non-blocking attribute inheritance: On some platforms (e.g. IRIX) +the socket created as a result of the accept(2) call inherits the +non-blocking attribute of the listening socket. One needs to consult the manual +pages or write a simple test program to see if this applies to a specific +platform.
    • +

    +

  • Anonymous memory mapping: The library allocates memory segments +for thread stacks by doing anonymous memory mapping (mmap(2)). This +mapping is somewhat different on SVR4 and BSD4.3 derived platforms. +

    +The memory mapping can be avoided altogether by using malloc(3) for +stack allocation. In this case the MALLOC_STACK macro should be +defined.

    • +
+

+All machine-dependent feature test macros should be defined in the +md.h header file. The assembly code for setjmp/longjmp +replacement functions for all CPU architectures should be placed in +the md.S file. +

+The current version of the library is ported to: +

    +
  • IRIX 6.x (both 32 and 64 bit)
    • +
  • Linux (kernel 2.x and glibc 2.x) on x86, Alpha, MIPS and MIPSEL, + SPARC, ARM, PowerPC, 68k, HPPA, S390, IA-64, and Opteron (AMD-64)
    • +
  • Solaris 2.x (SunOS 5.x) on x86, AMD64, SPARC, and SPARC-64
    • +
  • AIX 4.x
    • +
  • HP-UX 11 (both 32 and 64 bit)
    • +
  • Tru64/OSF1
    • +
  • FreeBSD on x86, AMD64, and Alpha
    • +
  • OpenBSD on x86, AMD64, Alpha, and SPARC
    • +
  • NetBSD on x86, Alpha, SPARC, and VAX
    • +
  • MacOS X (Darwin) on PowerPC (32 bit) and Intel (both 32 and 64 bit) [universal]
    • +
  • Cygwin
    • +
+

+ + +

Signals

+Signal handling in an application using State Threads should be treated the +same way as in a classical UNIX process application. There is no such +thing as per-thread signal mask, all threads share the same signal handlers, +and only asynchronous-safe functions can be used in signal handlers. +However, there is a way to process signals synchronously by converting a +signal event to an I/O event: a signal catching function does a write to +a pipe which will be processed synchronously by a dedicated signal handling +thread. The following code demonstrates this technique (error handling is +omitted for clarity): +
+
+/* Per-process pipe which is used as a signal queue. */
+/* Up to PIPE_BUF/sizeof(int) signals can be queued up. */
+int sig_pipe[2];
+
+/* Signal catching function. */
+/* Converts signal event to I/O event. */
+void sig_catcher(int signo)
+{
+  int err;
+
+  /* Save errno to restore it after the write() */
+  err = errno;
+  /* write() is reentrant/async-safe */
+  write(sig_pipe[1], &signo, sizeof(int));
+  errno = err;
+}
+
+/* Signal processing function. */
+/* This is the "main" function of the signal processing thread. */
+void *sig_process(void *arg)
+{
+  st_netfd_t nfd;
+  int signo;
+
+  nfd = st_netfd_open(sig_pipe[0]);
+
+  for ( ; ; ) {
+    /* Read the next signal from the pipe */
+    st_read(nfd, &signo, sizeof(int), ST_UTIME_NO_TIMEOUT);
+
+    /* Process signal synchronously */
+    switch (signo) {
+    case SIGHUP:
+      /* do something here - reread config files, etc. */
+      break;
+    case SIGTERM:
+      /* do something here - cleanup, etc. */
+      break;
+      /*      .
+              .
+         Other signals
+              .
+              .
+      */
+    }
+  }
+
+  return NULL;
+}
+
+int main(int argc, char *argv[])
+{
+  struct sigaction sa;
+        .
+        .
+        .
+
+  /* Create signal pipe */
+  pipe(sig_pipe);
+
+  /* Create signal processing thread */
+  st_thread_create(sig_process, NULL, 0, 0);
+
+  /* Install sig_catcher() as a signal handler */
+  sa.sa_handler = sig_catcher;
+  sigemptyset(&sa.sa_mask);
+  sa.sa_flags = 0;
+  sigaction(SIGHUP, &sa, NULL);
+
+  sa.sa_handler = sig_catcher;
+  sigemptyset(&sa.sa_mask);
+  sa.sa_flags = 0;
+  sigaction(SIGTERM, &sa, NULL);
+
+        .
+        .
+        .
+      
+}
+
+
+

+Note that if multiple processes are used (see below), the signal pipe should +be initialized after the fork(2) call so that each process has its +own private pipe. +

+ + +

Intra-Process Synchronization

+Due to the event-driven nature of the library scheduler, the thread context +switch (process state change) can only happen in a well-known set of +library functions. This set includes functions in which a thread may +"block": I/O functions (st_read(), st_write(), etc.), +sleep functions (st_sleep(), etc.), and thread synchronization +functions (st_thread_join(), st_cond_wait(), etc.). As a result, +process-specific global data need not to be protected by locks since a thread +cannot be rescheduled while in a critical section (and only one thread at a +time can access the same memory location). By the same token, +non thread-safe functions (in a traditional sense) can be safely used with +the State Threads. The library's mutex facilities are practically useless +for a correctly written application (no blocking functions in critical +section) and are provided mostly for completeness. This absence of locking +greatly simplifies an application design and provides a foundation for +scalability. +

+ + +

Inter-Process Synchronization

+The State Threads library makes it possible to multiplex a large number +of simultaneous connections onto a much smaller number of separate +processes, where each process uses a many-to-one user-level threading +implementation (N of M:1 mappings rather than one M:N +mapping used in native threading libraries on some platforms). This design +is key to the application's scalability. One can think about it as if a +set of all threads is partitioned into separate groups (processes) where +each group has a separate pool of resources (virtual address space, file +descriptors, etc.). An application designer has full control of how many +groups (processes) an application creates and what resources, if any, +are shared among different groups via standard UNIX inter-process +communication (IPC) facilities.

+There are several reasons for creating multiple processes: +

+

    +
  • To take advantage of multiple hardware entities (CPUs, disks, etc.) +available in the system (hardware parallelism).
    • +

    +

  • To reduce risk of losing a large number of user connections when one of +the processes crashes. For example, if C user connections (threads) +are multiplexed onto P processes and one of the processes crashes, +only a fraction (C/P) of all connections will be lost.
    • +

    +

  • To overcome per-process resource limitations imposed by the OS. For +example, if select(2) is used for event polling, the number of +simultaneous connections (threads) per process is +limited by the FD_SETSIZE parameter (see select(2)). +If FD_SETSIZE is equal to 1024 and each connection needs one file +descriptor, then an application should create 10 processes to support 10,000 +simultaneous connections.
    • +
+

+Ideally all user sessions are completely independent, so there is no need for +inter-process communication. It is always better to have several separate +smaller process-specific resources (e.g., data caches) than to have one large +resource shared (and modified) by all processes. Sometimes, however, there +is a need to share a common resource among different processes. In that case, +standard UNIX IPC facilities can be used. In addition to that, there is a way +to synchronize different processes so that only the thread accessing the +shared resource will be suspended (but not the entire process) if that resource +is unavailable. In the following code fragment a pipe is used as a counting +semaphore for inter-process synchronization: +

+#ifndef PIPE_BUF
+#define PIPE_BUF 512  /* POSIX */
+#endif
+
+/* Semaphore data structure */
+typedef struct ipc_sem {
+  st_netfd_t rdfd;  /* read descriptor */
+  st_netfd_t wrfd;  /* write descriptor */
+} ipc_sem_t;
+
+/* Create and initialize the semaphore. Should be called before fork(2). */
+/* 'value' must be less than PIPE_BUF. */
+/* If 'value' is 1, the semaphore works as mutex. */
+ipc_sem_t *ipc_sem_create(int value)
+{
+  ipc_sem_t *sem;
+  int p[2];
+  char b[PIPE_BUF];
+
+  /* Error checking is omitted for clarity */
+  sem = malloc(sizeof(ipc_sem_t));
+
+  /* Create the pipe */
+  pipe(p);
+  sem->rdfd = st_netfd_open(p[0]);
+  sem->wrfd = st_netfd_open(p[1]);
+
+  /* Initialize the semaphore: put 'value' bytes into the pipe */
+  write(p[1], b, value);
+
+  return sem;
+}
+
+/* Try to decrement the "value" of the semaphore. */
+/* If "value" is 0, the calling thread blocks on the semaphore. */
+int ipc_sem_wait(ipc_sem_t *sem)
+{
+  char c;
+
+  /* Read one byte from the pipe */
+  if (st_read(sem->rdfd, &c, 1, ST_UTIME_NO_TIMEOUT) != 1)
+    return -1;
+
+  return 0;
+}
+
+/* Increment the "value" of the semaphore. */
+int ipc_sem_post(ipc_sem_t *sem)
+{
+  char c;
+
+  if (st_write(sem->wrfd, &c, 1, ST_UTIME_NO_TIMEOUT) != 1)
+    return -1;
+
+  return 0;
+}
+
+
+

+ +Generally, the following steps should be followed when writing an application +using the State Threads library: +

+

    +
  1. Initialize the library (st_init()).
    2. +

    +

  2. Create resources that will be shared among different processes: + create and bind listening sockets, create shared memory segments, IPC + channels, synchronization primitives, etc.
    3. +

    +

  3. Create several processes (fork(2)). The parent process should + either exit or become a "watchdog" (e.g., it starts a new process when + an existing one crashes, does a cleanup upon application termination, + etc.).
    4. +

    +

  4. In each child process create a pool of threads + (st_thread_create()) to handle user connections.
    5. +
+

+ + +

Non-Network I/O

+ +The State Threads architecture uses non-blocking I/O on +st_netfd_t objects for concurrent processing of multiple user +connections. This architecture has a drawback: the entire process and +all its threads may block for the duration of a disk or other +non-network I/O operation, whether through State Threads I/O functions, +direct system calls, or standard I/O functions. (This is applicable +mostly to disk reads; disk writes are usually performed +asynchronously -- data goes to the buffer cache to be written to disk +later.) Fortunately, disk I/O (unlike network I/O) usually takes a +finite and predictable amount of time, but this may not be true for +special devices or user input devices (including stdin). Nevertheless, +such I/O reduces throughput of the system and increases response times. +There are several ways to design an application to overcome this +drawback: + +

+

 +

+ + +

Timeouts

+ +The timeout parameter to st_cond_timedwait() and the +I/O functions, and the arguments to st_sleep() and +st_usleep() specify a maximum time to wait since the last +context switch not since the beginning of the function call. + +

The State Threads' time resolution is actually the time interval +between context switches. That time interval may be large in some +situations, for example, when a single thread does a lot of work +continuously. Note that a steady, uninterrupted stream of network I/O +qualifies for this description; a context switch occurs only when a +thread blocks. + +

If a specified I/O timeout is less than the time interval between +context switches the function may return with a timeout error before +that amount of time has elapsed since the beginning of the function +call. For example, if eight milliseconds have passed since the last +context switch and an I/O function with a timeout of 10 milliseconds +blocks, causing a switch, the call may return with a timeout error as +little as two milliseconds after it was called. (On Linux, +select()'s timeout is an upper bound on the amount of +time elapsed before select returns.) Similarly, if 12 ms have passed +already, the function may return immediately. + +

In almost all cases I/O timeouts should be used only for detecting a +broken network connection or for preventing a peer from holding an idle +connection for too long. Therefore for most applications realistic I/O +timeouts should be on the order of seconds. Furthermore, there's +probably no point in retrying operations that time out. Rather than +retrying simply use a larger timeout in the first place. + +

The largest valid timeout value is platform-dependent and may be +significantly less than INT_MAX seconds for select() +or INT_MAX milliseconds for poll(). Generally, you +should not use timeouts exceeding several hours. Use +ST_UTIME_NO_TIMEOUT (-1) as a special value to +indicate infinite timeout or indefinite sleep. Use +ST_UTIME_NO_WAIT (0) to indicate no waiting at all. + +

+

List of Blocking Functions
+

+

+

+

+

+ + + +

Types

+ +The State Thread library defines the following types in the st.h +header file: +

+

+
st_thread_t
+
st_cond_t
+
st_mutex_t
+
st_utime_t
+
st_netfd_t
+
+

+

+

+ + +

st_thread_t

+ +Thread type. +

+

Syntax
+ +
+#include <st.h>
+
+typedef void *  st_thread_t;
+
+

+

Description
+ +A thread is represented and identified by a pointer to an opaque data +structure. This pointer is a required parameter for most of the functions +that operate on threads. +

+The thread identifier remains valid until the thread returns from its root +function and, if the thread was created joinable, is joined. +

+

+

+ + +

st_cond_t

+ +Condition variable type. +

+

Syntax
+ +
+#include <st.h>
+
+typedef void *  st_cond_t;
+
+

+

Description
+ +A condition variable is an opaque object identified by a pointer. +Condition variables provide synchronization primitives to wait for or wake +up threads waiting for certain conditions to be satisfied. +

+In the State Threads library there is no need to lock a mutex before +waiting on a condition variable. +

+

+

+ + +

st_mutex_t

+ +Mutex type. +

+

Syntax
+ +
+#include <st.h>
+
+typedef void *  st_mutex_t;
+
+

+

Description
+ +A mutex is an opaque object identified by a pointer. +Mutual exclusion locks (mutexes) are used to serialize the execution of +threads through critical sections of code. +

+If application using the State Threads library is written with no +I/O or control yielding in critical sections (that is no +blocking functions in critical sections), then there is +no need for mutexes.

+These mutexes can only be used for intra-process thread synchronization. +They cannot be used for inter-process synchronization. +

+

+

+ + +

st_utime_t

+ +High resolution time type ("u" stands for "micro"). +

+

Syntax
+ +
+#include <st.h>
+
+typedef unsigned long long  st_utime_t;
+
+

+

Description
+ +This datatype (unsigned 64-bit integer) represents high-resolution real time +expressed in microseconds since some arbitrary time in the past. It is not +correlated in any way to the time of day. +

+

+

+ + +

st_netfd_t

+ +File descriptor type. +

+

Syntax
+ +
+#include <st.h>
+
+typedef void *  st_netfd_t;
+
+

+

Description
+ +This datatype typically represents any open end point of network +communication (socket, end point of a pipe, FIFO, etc.) but can +encapsulate any open file descriptor. Objects of this type are +identified by a pointer to an opaque data structure. + +

+

+

+ + +

st_switch_cb_t

+ +Context switch callback function type. +

+

Syntax
+ +
+#include <st.h>
+
+typedef void (*st_switch_cb_t)(void);
+
+

+

Description
+ +This datatype is a convenience type for describing a pointer +to a function that will be called when a thread is set to stop +or set to run. +This feature is available only when ST_SWITCH_CB is defined +in <st.h>. + +

+

+

+ + +

Error Handling

+ + +All State Threads library non-void functions return on success either a +non-negative integer or a pointer to a newly created object (constructor-type +functions). On failure they return either -1 or a NULL +pointer respectively and set global errno to indicate the error. +It is safe to use errno because it is set right before the function +return and only one thread at a time can modify its value.

+The perror(3) function can be used to produce an error message on the +standard error output. +

+

+

+ + +

Library Initialization

+ +

+

+
st_init()
+
st_getfdlimit()
+
st_set_eventsys()
+
st_get_eventsys()
+
st_get_eventsys_name()
+

+These functions operate on a callback function of type +st_switch_cb_t: +

st_set_switch_in_cb()
+
st_set_switch_out_cb()
+
+

+

+

+ + +

st_init()

+ +Initializes the runtime. +

+

Syntax
+ +
+#include <st.h>
+
+int st_init(void);
+
+

+

Parameters
+None. +

+

Returns
+Upon successful completion, a value of 0 is returned. +Otherwise, a value of -1 is returned and errno is set +to indicate the error. +

+

Description
+This function initializes the library runtime. It should be called near +the beginning of the application's main() function before any other +State Threads library function is called.

+Among other things, this function limits the number of open file descriptors +to the OS imposed per-process maximum number or, if select(2) is +used, to FD_SETSIZE, whichever is less (getrlimit(2)). +This limit can be +retrieved by st_getfdlimit(). It also sets the +disposition of the SIGPIPE signal to SIG_IGN (to be ignored) +(signal(5)). +

+Unlike POSIX threads, a new process created by the fork(2) system +call is an exact copy of the calling process and all state threads +which are running in the parent do exist in the child. That means that +st_init() may be called either before or after multiple processes +are created by fork(2). +

+If the library runtime is not properly initialized (e.g., st_init() +is accidentally omitted), then the process will receive either an arithmetic +exception (SIGFPE or SIGTRAP) or segmentation fault (SIGSEGV) signal upon +new thread creation or the first context switch, respectively. +

+

+

+ +

st_getfdlimit()

+ +Returns the maximum number of file descriptors that the calling process +can open. +

+

Syntax
+ +
+#include <st.h>
+
+int st_getfdlimit(void);
+
+

+

Parameters
+None. +

+

Returns
+The maximum number of file descriptors that the calling process can open. +If this function is called before the library is successfully initialized by +st_init(), a value of -1 is returned. +

+

Description
+This function returns the limit on the number of open file descriptors which +is set by the st_init() function. +

+

+

+ + +

st_set_eventsys()

+ +Sets event notification mechanism. +

+

Syntax
+ +
+#include <st.h>
+
+int st_set_eventsys(int eventsys);
+
+

+

Parameters
+st_set_eventsys() has the following parameter:

+eventsys

+An integer value identifying selected event notification mechanism. The +following values are defined in the st.h header file: +

+ + + + + + + + + + + + + + + +
ST_EVENTSYS_DEFAULTUse default event notification mechanism. Usually it's select(2) +but if the library was compiled with the USE_POLL macro defined +then the default is poll(2).
ST_EVENTSYS_SELECTUse select(2) as an event notification mechanism.
ST_EVENTSYS_POLLUse poll(2) as an event notification mechanism.
ST_EVENTSYS_ALTUse an alternative event notification mechanism. The actual +mechanism selected depends on OS support. For example, epoll(4) +will be used on Linux if supported and kqueue(2) will be used +on FreeBSD/OpenBSD. If the OS supports no alternative event +notification mechanism, setting ST_EVENTSYS_ALT has no effect +and the ST_EVENTSYS_DEFAULT mechanism will be used.
+

+

Returns
+Upon successful completion, a value of 0 is returned. +Otherwise, a value of -1 is returned and errno is set +to indicate the error:

+ + + + + +
EINVAL +The supplied eventsys parameter has an invalid value. +
EBUSY +The event notification mechanism has already been set. +
+

+

Description
+This function sets the event notification mechanism that will be used by +the State Threads library. To have any effect, it must be called +before the st_init() function which performs +the actual initialization. If st_set_eventsys() is not called, +st_init() will set the ST_EVENTSYS_DEFAULT +mechanism. The mechanism cannot be changed once set. +

+There are no strict rules for selecting an event notification +mechanism. The "best" one depends on how your application behaves. +Try a few to see which one works best for you. As a rule of +thumb, you should use the ST_EVENTSYS_ALT mechanism if your +application deals with a very large number of network connections of +which only a few are active at once. +

+

+

+ +

st_get_eventsys()

+ +Returns the integer value identifying the event notification mechanism +being used by the State Threads library. +

+

Syntax
+ +
+#include <st.h>
+
+int st_get_eventsys(void);
+
+

+

Parameters
+None. +

+

Returns
+The integer value identifying the current event notification mechanism. +This value can be one of the following (see st_set_eventsys()): +ST_EVENTSYS_SELECT, ST_EVENTSYS_POLL, or +ST_EVENTSYS_ALT. Future versions of the library may return other +values. If a mechanism hasn't been set yet, a value of -1 is returned. +

+

Description
+This function returns the integer value identifying the event notification +mechanism which is actually being used by the State Threads library. +

+

+

+ +

st_get_eventsys_name()

+ +Returns the name of the event notification mechanism being used by the +State Threads library. +

+

Syntax
+ +
+#include <st.h>
+
+const char *st_get_eventsys_name(void);
+
+

+

Parameters
+None. +

+

Returns
+The string identifying the current event notification mechanism. If a +mechanism hasn't been set yet (see st_set_eventsys()), an empty string is +returned. Possible return values are "select", +"poll", "kqueue", or "epoll". Future versions +of the library may return other values. +

+

Description
+This function returns the string identifying the event notification +mechanism which is actually being used by the State Threads library. +

+

+

+ + +

st_set_switch_in_cb()

+ + +

st_set_switch_out_cb()

+ +Set the optional callback function for thread switches. +

+

Syntax
+ +
+#include <st.h>
+
+st_switch_cb_t st_set_switch_in_cb(st_switch_cb_t cb);
+st_switch_cb_t st_set_switch_out_cb(st_switch_cb_t cb);
+
+

+

Parameters
+st_set_switch_in_cb() and st_set_switch_out_cb() have the +following parameter:

+cb

+A function to be called when a thread is resumed and stopped respectively.

+

Returns
+The previous callback function pointer. +

+

Description
+These functions set the callback for when a thread is resumed and stopped +respectively. After being called any thread switch will call the callback. +Use a NULL pointer to disable the callback (this is the default). +Use st_thread_self() or thread +specific data to differentiate between threads.

+These functions can be called at any time.

+This feature is available only when ST_SWITCH_CB is defined +in <st.h>. +

+

+

+ + +

Thread Control and Identification

+ +

+These functions operate on a thread object of type +st_thread_t. +

+

+
st_thread_create()
+
st_thread_exit()
+
st_thread_join()
+
st_thread_self()
+
st_thread_interrupt()
+
st_sleep()
+
st_usleep()
+
st_randomize_stacks()
+
+

+

+

+ +

st_thread_create()

+ +Creates a new thread. +

+

Syntax
+ +
+#include <st.h>
+
+st_thread_t st_thread_create(void *(*start)(void *arg), void *arg,
+                             int joinable, int stack_size);
+
+
+

+

Parameters
+st_thread_create() has the following parameters:

+start

+A pointer to the thread's start function, which is called as the root of the +new thread. Return from this function terminates a thread.

+arg

+A pointer to the root function's only parameter.

+joinable

+Specifies whether the thread is joinable or unjoinable. If this parameter +is zero, the thread is unjoinable. Otherwise, it is joinable. +See also st_thread_join().

+stack_size

+Specifies your preference for the size of the stack, in bytes, associated +with the newly created thread. If you pass zero in this parameter, the +default stack size will be used. The default stack size is 128 KB on IA-64 +and 64 KB on all other platforms. On IA-64 only a half of stack_size +bytes is used for the memory stack. The other half is used for the register +stack backing store. +

+

Returns
+Upon successful completion, a new thread identifier is returned (this +identifier remains valid until the thread returns from its start function). +Otherwise, NULL is returned and errno is set +to indicate the error. +

+

Description
+This function creates a new thread. Note that the total number of threads +created by the application is limited by the amount of swap space available. +Upon thread creation, stack_size bytes are reserved on the swap +space. The stack pages are not actually used (valid) until touched by the +application. +

+

+

+ +

st_thread_exit()

+ +Terminates the calling thread. +

+

Syntax
+ +
+#include <st.h>
+
+void st_thread_exit(void *retval);
+
+

+

Parameters
+st_thread_exit() has the following parameters:

+retval

+If the thread is joinable, then the value retval may be retrieved +by st_thread_join(). If a thread returns from its +start function, it acts as if it had called st_thread_exit() with +retval as the value returned. +

+

Returns
+Nothing. +

+

Description
+This function terminates the calling thread. When a thread exits, per-thread +private data is destroyed by invoking the destructor function for any +non-NULL thread specific values associated with active keys (see +st_key_create()). This function is implicitly called +when a thread returns from its start function.

+When the last thread terminates the process exits with a zero status value. +

+

+

+ +

st_thread_join()

+ +Blocks the calling thread until a specified thread terminates. +

+

Syntax
+ +
+#include <st.h>
+
+int st_thread_join(st_thread_t thread, void **retvalp);
+
+

+

Parameters
+st_thread_join() has the following parameters:

+thread

+A valid identifier for the thread that is to be joined.

+retvalp

+If this parameter is not NULL, then the exit value of the +thread will be placed in the location referenced by this parameter +(see st_thread_exit()). +

+

Returns
+Upon successful completion, a value of 0 is returned. +Otherwise, a value of -1 is returned and errno is set +to indicate the error:

+ + + + + +
EINVALTarget thread is unjoinable.
EINVALOther thread already waits on the same +joinable thread.
EDEADLKTarget thread is the same as the +calling thread.
EINTRCurrent thread was interrupted by +st_thread_interrupt().
+

+

Description
+This function is used to synchronize the termination of a thread and possibly +retrieve its exit value. Several threads cannot wait for the same thread +to complete - one of the calling threads operates successfully, and the others +terminate with the error. The calling thread is not blocked if the target +thread has already terminated. +

+

+

+ +

st_thread_self()

+ +Identifies the calling thread. +

+

Syntax
+ +
+#include <st.h>
+
+st_thread_t st_thread_self(void);
+
+

+

Parameters
+None. +

+

Returns
+Always returns a valid reference to the calling thread - a self-identity. +

+

Description
+This function identifies the calling thread. This is the same identifier +that the creating thread obtains from +st_thread_create(). +

+

+

+ +

st_thread_interrupt()

+ +Interrupts a target thread. +

+

Syntax
+ +
+#include <st.h>
+
+void st_thread_interrupt(st_thread_t thread);
+
+

+

Parameters
+st_thread_interrupt() has the following parameters:

+thread

+A valid identifier for the thread being interrupted. +

+

Returns
+Nothing. +

+

Description
+This function interrupts (unblocks) a target thread that is blocked in one +of the blocking functions. A function that was interrupted +returns an error and sets errno to EINTR. It is up to +the target thread to act upon an interrupt (e.g., it may exit or just +abort the current transaction).

+Note: State Threads library functions are never interrupted by a +caught signal. A blocking library function returns an error and sets +errno to EINTR only if the current thread was +interrupted via st_thread_interrupt(). +

+If a target thread is already runnable or running (e.g., it is a newly +created thread or calling thread itself), this function will prevent it +from subsequent blocking. In other words, the interrupt will be "delivered" +only when a target thread is about to block. +

+

+

+ +

st_sleep(), st_usleep()

+ +Suspends current thread for a specified amount of time. +

+

Syntax
+ +
+#include <st.h>
+
+int st_sleep(int secs);
+
+int st_usleep(st_utime_t usecs);
+
+

+

Parameters
+st_sleep() has the following parameters:

+secs

+The number of seconds you want the thread to sleep for. +

+st_usleep() has the following parameters:

+usecs

+The number of microseconds you want the thread to sleep for. This parameter +is a variable of type st_utime_t. +

+

Returns
+Upon successful completion, a value of 0 is returned. +Otherwise, a value of -1 is returned and errno is set +to indicate the error:

+ + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
+

+

Description
+These functions suspend the calling thread from execution for a specified +number of seconds (st_sleep()) or microseconds (st_usleep()). +

+ +If zero is passed as a parameter to st_sleep(), or +ST_UTIME_NO_WAIT (0) is passed to +st_usleep(), the calling thread yields, thus potentially +allowing another thread to run. + +

+ +If -1 is passed as a parameter to st_sleep(), or +ST_UTIME_NO_TIMEOUT (-1) is passed to +st_usleep(), the calling thread will be suspended permanently. +It can be resumed again by interrupting it via st_thread_interrupt(). + +

+

+

+ +

st_randomize_stacks()

+ +Turns stack base address randomization on or off. +

+

Syntax
+ +
+#include <st.h>
+
+int st_randomize_stacks(int on);
+
+

+

Parameters
+st_randomize_stacks() has the following parameters:

+on

+If this parameter has a non-zero value, the State Threads library +randomizes the base addresses of stacks allocated for threads created +after this call. Otherwise new threads' stacks are typically page +aligned. +

+

Returns
+The previous state of stack randomization (a value of 0 if it +was off and a non-zero value otherwise). +

+

Description
+Randomizing state threads' stack bases may improve cache performance on +some systems when large numbers of state threads all perform roughly the +same work, as when they all start from the same root function. On many +modern systems the performance increase is negligible. You should +compare your application's performance with this feature on and off to +see if you really need it. +

+When randomization is enabled, new stacks are allocated one page larger +to accomodate the randomization. +

+This call affects only threads created afterward. It has no effect on +existing threads. +

+

+

+ + +

Per-Thread Private Data

+ +These functions allow to associate private data with each of the threads in +a process. +

+

+
st_key_create()
+
st_key_getlimit()
+
st_thread_setspecific()
+
st_thread_getspecific()
+
+

+

+

+ +

st_key_create()

+ +Creates a key (non-negative integer) that can be used by all +threads in the process to get and set thread-specific data. +

+

Syntax
+ +
+#include <st.h>
+
+int st_key_create(int *keyp, void (*destructor)(void *));
+
+

+

Parameters
+st_key_create() has the following parameters:

+keyp

+The newly created key is returned in the memory pointed to by this parameter. +The new key can be used with +st_thread_setspecific() and +st_thread_getspecific().

+destructor

+Specifies an optional destructor function for the private data associated +with the key. This function can be specified as NULL. +Upon thread exit (see st_thread_exit()), if a key +has a non-NULL destructor and has a non-NULL value +associated with that key, then the destructor function will be +called with the associated value. +

+

Returns
+Upon successful completion, a value of 0 is returned. +Otherwise, a value of -1 is returned and errno is set +to indicate the error:

+ + +
EAGAINThe limit on the total number of keys per +process has been exceeded (see st_key_getlimit()). +
+

+

Description
+If this function is successful, every thread in the same process is capable +of associating private data with the new key. After a new key is created, all +active threads have the value NULL associated with that key. +After a new thread is created, the value NULL is associated with +all keys for that thread. If a non-NULL destructor function is +registered with a new key, it will be called at one of two times, as long as +the private data is not NULL: + +

+The key maintains independent data values for each binding thread. A thread +can get access only to its own thread-specific data. There is no way to +deallocate a private data key once it is allocated. +

+

+

+ +

st_key_getlimit()

+ +Returns the key limit. +

+

Syntax
+ +
+#include <st.h>
+
+int st_key_getlimit(void);
+
+

+

Parameters
+None. +

+

Returns
+The limit on the total number of keys per process. +

+

Description
+This function can be used to obtain the limit on the total number of keys +per process (see st_key_create()). +

+

+

+ +

st_thread_setspecific()

+ +Sets per-thread private data. +

+

Syntax
+ +
+#include <st.h>
+
+int st_thread_setspecific(int key, void *value);
+
+

+

Parameters
+st_thread_setspecific() has the following parameters:

+key

+This parameter represents a key with which thread-specific data is associated. +

+value

+The per-thread private data, or more likely, a pointer to the data which is +associated with key. +

+

Returns
+Upon successful completion, a value of 0 is returned. +Otherwise, a value of -1 is returned and errno is set +to indicate the error:

+ + + +
EINVALThe specified key is invalid.
+

+

Description
+This function associates a thread-specific value with key. +Different threads may bind different values to the same key.

+If the thread already has non-NULL private data associated with +key, and if the destructor function for that key is not +NULL, this destructor function will be called before setting the +new data value. +

+

+

+ +

st_thread_getspecific()

+ +Retrieves the per-thread private data for the current thread. +

+

Syntax
+ +
+#include <st.h>
+
+void *st_thread_getspecific(int key);
+
+

+

Parameters
+st_thread_getspecific() has the following parameters:

+key

+This parameter represents a key with which thread-specific data is associated. +

+

Returns
+The thread-specific data associated with key. If no data is +associated with key, then NULL is returned. +

+

Description
+This function returns the calling thread's value that is bound to the +specified key (see +st_thread_setspecific()). +

+

+

+ + +

+ +Creates a new condition variable. +

+

Syntax
+ +
+#include <st.h>
+
+st_cond_t st_cond_new(void);
+
+

+

Parameters
+None. +

+

Returns
+Upon successful completion, a new condition variable identifier is returned. +Otherwise, NULL is returned and errno is set +to indicate the error. +

+

Description
+This function creates a new condition variable. +

+

+

+ +

st_cond_destroy()

+ +Destroys a condition variable. +

+

Syntax
+ +
+#include <st.h>
+
+int st_cond_destroy(st_cond_t cvar);
+
+

+

Parameters
+st_cond_destroy() has the following parameters:

+cvar

+An identifier of the condition variable object to be destroyed. +

+

Returns
+Upon successful completion, a value of 0 is returned. +Otherwise, a value of -1 is returned and errno is set +to indicate the error:

+ + + +
EBUSYThe condition variable is currently being +used by one or more threads.
+

+

Description
+This function destroys a condition variable. The caller is responsible for +ensuring that the condition variable is no longer in use. +

+

+

+ +

st_cond_wait()

+ +Waits on a condition. +

+

Syntax
+ +
+#include <st.h>
+
+int st_cond_wait(st_cond_t cvar);
+
+

+

Parameters
+st_cond_wait() has the following parameters:

+cvar

+The condition variable on which to wait. +

+

Returns
+Upon successful completion, a value of 0 is returned. +Otherwise, a value of -1 is returned and errno is set +to indicate the error:

+ + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
+

+

Description
+This function is used to block on a condition variable. A return from this +function does not guarantee that the condition or event for which the caller +was waiting actually occurred. It is the responsibility of the caller +to recheck the condition wait predicate before proceeding.

+Note: The State Threads library scheduling guarantees that the +condition cannot change between the checking and blocking, therefore there +is no need for mutex protection. You must not call any +blocking functions between the condition checking and +the st_cond_wait() call. +

+

+

+ +

st_cond_timedwait()

+ +Waits on a condition. +

+

Syntax
+ +
+#include <st.h>
+
+int st_cond_timedwait(st_cond_t cvar, st_utime_t timeout);
+
+

+

Parameters
+st_cond_timedwait() has the following parameters:

+cvar

+The condition variable on which to wait.

+timeout

+If the number of microseconds specified by this parameter passes before the +waiting thread is signalled, an error is returned. This parameter is a +variable of type st_utime_t. Note that this +time value is a time delta; it is not an absolute time. +Also note that timeouts are measured since +the last context switch. +

+

Returns
+Upon successful completion, a value of 0 is returned. +Otherwise, a value of -1 is returned and errno is set +to indicate the error:

+ + + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
ETIMEThe timeout occurred before the thread was +awakened by st_cond_signal() or +st_cond_broadcast().
+

+

Description
+This function works the same way as st_cond_wait(), +except that an error is returned if the number of microseconds specified by +timeout passes before the waiting thread is signalled. +

+

+

+ +

st_cond_signal()

+ +Unblocks a thread waiting on a condition variable. +

+cvar

+The condition variable to signal. +

+

Returns
+Always zero. +

+

Description
+This function unblocks (signals) one of the threads that are blocked on +cvar at the time of the call. If no thread is waiting on the +condition variable, the signal operation is a no-op. +

+

+

Description
+A thread that calls this function will block until it can gain exclusive +ownership of a mutex, and retains ownership until it calls +st_mutex_unlock(). +

+

+

+ +

st_mutex_trylock()

+ +Attempts to acquire a mutex. +

+

+

Syntax
+ +
+#include <st.h>
+
+int st_mutex_unlock(st_mutex_t lock);
+
+

+

Parameters

+

+

Description
+This function releases a specified mutex object previously acquired by +st_mutex_lock() or +st_mutex_trylock(). Only the thread that locked +a mutex should unlock it. +

+

+

+ + +

Timing

+ +

+

+
st_utime()
+
st_set_utime_function()
+
st_timecache_set()
+
st_time()
+
+

+

+

+ +

st_utime()

+ +Returns current high-resolution time. +

+

Syntax
+ +
+#include <st.h>
+
+st_utime_t st_utime(void);
+
+

+

Parameters
+None. +

+

Returns
+Current high-resolution time value of type +st_utime_t. +

+

Description
+This function returns the current high-resolution time. Time is +expressed as microseconds since some arbitrary time in the past. It is +not correlated in any way to the time of day. See also st_utime_t and st_time(). +

+

+

+ +

st_set_utime_function()

+ +Set high-resolution time function. +

+

Syntax
+ +
+#include <st.h>
+
+int st_set_utime_function(st_utime_t (*func)(void));
+
+

+

Parameters
+st_set_utime_function() has the following parameters:

+func

+This function will be called to get high-resolution time instead of the +default st_utime() function. It must return +number of microseconds since some arbitrary time in the past. +

+

Returns
+Upon successful completion, a value of 0 is returned. +Otherwise, a value of -1 is returned and errno is set +to EINVAL to indicate the error. +

+

Description
+This function may be called to replace the default implementation of the +st_utime() function. It must be called before the ST +library has been initialized (see st_init()). +The user-provided function func will be invoked whenever +st_utime() is called to obtain current high-resolution time. +Replacing default implementation may be useful, for example, for taking +advantage of high performance CPU cycle counters. +

+

+

+ +

st_timecache_set()

+ +Turns the time caching on or off. +

+

Syntax
+ +
+#include <st.h>
+
+int st_timecache_set(int on);
+
+

+

Parameters
+st_timecache_set() has the following parameters:

+on

+If this parameter has a non-zero value, the time caching is turned on +(enabled). Otherwise, the time caching is turned off (disabled). +By default time caching is disabled. +

+

Returns
+The previous state of time caching (a value of 0 if it was off and +a value of 1 otherwise). +

+

Description
+The State Threads library has the ability to "cache" the time value that is +reported by the time(2) system call. If the time caching is enabled +by calling this function with a non-zero argument, then the result value +of time(2) will be stored and updated at most once per second. The +cached time can be retrieved by st_time(). +By default time caching is disabled. +You may enable or disable time caching at any time but generally +you enable it once (if desired) during program initialization.

+Note: There are some pathological cases (e.g., very heavy loads during +application benchmarking) when a single thread runs for a long time without +giving up control and the cached time value is not updated properly. If you +always need "real-time" time values, don't enable the time caching. +

+

+

+ +

st_time()

+ +Returns the value of time in seconds since 00:00:00 UTC, January 1, 1970. +

+

Syntax
+ +
+#include <st.h>
+
+time_t st_time(void);
+
+

+

Parameters
+None. +

+

Returns
+The value of time in seconds since 00:00:00 UTC, January 1, 1970 as reported +by the time(2) system call. +

+

Description
+If the time caching was enabled by +st_timecache_set(), then this function returns +the cached result. Otherwise, it just calls time(2). +

+

+

+ + +

I/O Functions

+ +

+Most State Threads library I/O functions look like corresponding C library +functions with two exceptions: +

    +
  • They operate on file descriptor objects of type +st_netfd_t.
    • +
  • They take an additional argument of type +st_utime_t which represents an inactivity +timeout: if no I/O is possible during this amount of time, I/O functions +return an error code and set errno to ETIME. + +The boundary values ST_UTIME_NO_WAIT (0) and +ST_UTIME_NO_TIMEOUT (-1) for this argument indicate +that the thread should wait no time (function returns immediately) or +wait forever (never time out), respectively. + +Note that timeouts are measured since the +last context switch. +

st_netfd_open()

+ +Creates a new file descriptor object. +

+

Syntax
+ +
+#include <st.h>
+
+st_netfd_t st_netfd_open(int osfd);
+
+

+

Parameters
+st_netfd_open() has the following parameters:

+osfd

+ +Any open OS file descriptor; can be obtained from calls to +functions including, but not restricted to, pipe(2), socket(3), +socketpair(3), fcntl(2), dup(2), etc. + + +

+

Returns
+Upon successful completion, a new file descriptor object identifier is +returned. Otherwise, NULL is returned and errno is set +to indicate the error. +

+

Description
+This function creates a new file descriptor object of type +st_netfd_t.

+ +Note: Among other things, this function sets a non-blocking +flag on the underlying OS file descriptor. You should not modify this +flag directly. Also, once an st_netfd_t +has been created with a given file descriptor, you should avoid +passing that descriptor to normal I/O or stdio functions. Since the +O_NONBLOCK flag is shared across dup(2), this applies to +dup()'ed file descriptors as well - for instance, if you pass +standard output or standard input to st_netfd_open(), then +you should use st_write() instead of write +or fprintf when writing to standard error as well - since all +three descriptors could point to the same terminal. If necessary, you +can still use write directly if you remember to check +errno for EAGAIN, but fprintf and other +stdio functions should be avoided completely because, at least on +Linux, the stdio library cannot be made to work reliably with +non-blocking files. (This only applies to file descriptors which are +passed to st_netfd_open() or st_netfd_open_socket(), or which are +related to such descriptors through dup(); other file +descriptors are untouched by State Threads.) +

+

+

+ +

st_netfd_open_socket()

+ +Creates a new file descriptor object from a socket. +

+

Syntax
+ +
+#include <st.h>
+
+st_netfd_t st_netfd_open_socket(int osfd);
+
+

+

Parameters
+st_netfd_open_socket() has the following parameters:

+osfd

+An open OS file descriptor which is a socket initially obtained from a +socket(3) or socketpair(3) call. +

+

Returns
+Upon successful completion, a new file descriptor object identifier is +returned. Otherwise, NULL is returned and errno is set +to indicate the error. +

+

Description
+This function creates a new file descriptor object of type +st_netfd_t which represents an open end +point of network communication.

+Unlike the st_netfd_open() function which may be used +on OS file descriptors of any origin, st_netfd_open_socket() must +be used only on sockets. It is slightly more efficient than +st_netfd_open().

+Note: Among other things, this function sets a non-blocking flag +on the underlying OS socket. You should not modify this flag directly. +See st_netfd_open(). +

+

+

+ +

st_netfd_free()

+ +Frees a file descriptor object without closing the underlying OS file +descriptor. +

+

Syntax
+ +
+#include <st.h>
+
+void st_netfd_free(st_netfd_t fd);
+
+

+

Parameters
+st_netfd_free() has the following parameters:

+fd

+A file descriptor object identifier (see +st_netfd_t). +

+

Returns
+Nothing. +

+

Description
+This function frees the memory and other resources identified by the +fd parameter without closing the underlying OS file descriptor. +Any non-NULL descriptor-specific data is destroyed by invoking +the specified destructor function (see st_netfd_setspecific()).

A thread should +not free file descriptor objects that are in use by other threads +because it may lead to unpredictable results (e.g., a freed file +descriptor may be reused without other threads knowing that). +

+

+

+ +

st_netfd_close()

+ +Closes a file descriptor. +

+

Syntax
+ +
+#include <st.h>
+
+int st_netfd_close(st_netfd_t fd);
+
+

+

Parameters
+st_netfd_close() has the following parameters:

+fd

+A file descriptor object identifier (see +st_netfd_t). +

+

Returns
+Upon successful completion, a value of 0 is returned. +Otherwise, a value of -1 is returned and errno is set +to indicate the error. +

+

Description
+This function closes the underlying OS file descriptor, frees the memory and +other resources identified by the fd parameter. Any non-NULL +descriptor-specific data is destroyed by invoking the specified destructor +function (see st_netfd_setspecific()).

+A thread should not close file descriptor objects that are in use by other +threads because it may lead to unpredictable results (e.g., a closed +file descriptor may be reused without other threads knowing that). +

+

+

+ +

st_netfd_fileno()

+ +Returns an underlying OS file descriptor. +

+

Syntax
+ +
+#include <st.h>
+
+int st_netfd_fileno(st_netfd_t fd);
+
+

+

Parameters
+st_netfd_fileno() has the following parameters:

+fd

+A file descriptor object identifier (see +st_netfd_t). +

+

Returns
+An underlying OS file descriptor. +

+

Description
+This function returns the integer OS file descriptor associated with the named +file descriptor object. +

+

+

+ +

st_netfd_setspecific()

+ +Sets per-descriptor private data. +

+

Syntax
+ +
+#include <st.h>
+
+void st_netfd_setspecific(st_netfd_t fd, void *value,
+                          void (*destructor)(void *));
+
+

+

Parameters
+st_netfd_setspecific() has the following parameters:

+fd

+A valid file descriptor object identifier (see +st_netfd_t). +

+value

+The per-descriptor private data, or more likely, a pointer to the data which +is being associated with the named file descriptor object. +

+destructor

+Specifies an optional destructor function for the private data associated +with fd. This function can be specified as NULL. +If value is not NULL, then this destructor function will +be called with value as an argument upon freeing the file descriptor +object (see st_netfd_free() and +st_netfd_close()). +

+

Returns
+Nothing. +

+

Description
+This function allows to associate any data with the specified file +descriptor object (network connection). If a non-NULL destructor +function is registered, it will be called at one of two times, as long as +the associated data is not NULL: +
    +
  • when private data is replaced by calling +st_netfd_setspecific() again +
  • upon freeing the file descriptor object (see +st_netfd_free() and +st_netfd_close()) +
+

+

+

+ +

st_netfd_getspecific()

+ +Retrieves the per-descriptor private data. +

+

Syntax
+ +
+#include <st.h>
+
+void *st_netfd_getspecific(st_netfd_t fd);
+
+

+

Parameters
+st_netfd_getspecific() has the following parameters:

+fd

+A valid file descriptor object identifier (see +st_netfd_t). +

+

Returns
+The data associated with the named file descriptor object. If no data is +associated with fd, then NULL is returned. +

+

Description
+This function allows to retrieve the data that was associated with the +specified file descriptor object (see +st_netfd_setspecific()). +

+

+

+ +

st_netfd_serialize_accept()

+ +Serializes all subsequent accept(3) calls on a specified file +descriptor object. +

+

Syntax
+ +
+#include <st.h>
+
+int st_netfd_serialize_accept(st_netfd_t fd);
+
+

+

Parameters
+st_netfd_serialize_accept() has the following parameters:

+fd

+A file descriptor object identifier (see +st_netfd_t) which has been successfully created +from a valid listening socket by st_netfd_open() or +st_netfd_open_socket(). +

+

Returns
+Upon successful completion, a value of 0 is returned. +Otherwise, a value of -1 is returned and errno is set +to indicate the error. +

+

Description
+On some platforms (e.g., Solaris 2.5 and possibly other SVR4 implementations) +accept(3) calls from different processes on +the same listening socket (see bind(3), listen(3)) must be +serialized. This function causes all subsequent accept(3) calls +made by st_accept() on the specified file descriptor +object to be serialized. +

+st_netfd_serialize_accept() must be called before +creating multiple server processes via fork(2). If the application +does not create multiple processes to accept network connections on +the same listening socket, there is no need to call this function. +

+Deciding whether or not to serialize accepts is tricky. On some +platforms (IRIX, Linux) it's not needed at all and +st_netfd_serialize_accept() is a no-op. On other platforms +it depends on the version of the OS (Solaris 2.6 doesn't need it but +earlier versions do). Serializing accepts does incur a slight +performance penalty so you want to enable it only if necessary. Read +your system's manual pages for accept(2) and select(2) +to see if accept serialization is necessary on your system. +

+st_netfd_serialize_accept() allocates resources that are +freed upon freeing of the specified file descriptor object (see +st_netfd_free() and +st_netfd_close()). +

+

+

+ +

st_netfd_poll()

+ +Waits for I/O on a single file descriptor object. +

+

Syntax
+ +
+#include <st.h>
+
+int st_netfd_poll(st_netfd_t fd, int how, st_utime_t timeout);
+
+

+

Parameters
+st_netfd_poll() has the following parameters:

+fd

+A file descriptor object identifier (see +st_netfd_t). +

+how

+Specifies I/O events of interest. This parameter can be constructed by +OR-ing any combination of the following event flags which are defined +in the poll.h header file:

+ + + + + +
POLLINfd is readable.
POLLOUTfd is is writable.
POLLPRIfd has an exception condition.
+

+timeout

+Amount of time in microseconds the call will block waiting for I/O +to become ready. This parameter is a variable of type +st_utime_t. If this time expires without any +I/O becoming ready, st_netfd_poll() returns an error and sets +errno to ETIME. +Note that timeouts are measured since the +last context switch. +

+

Returns
+If the named file descriptor object is ready for I/O within the specified +amount of time, a value of 0 is returned. Otherwise, a value +of -1 is returned and errno is set to indicate the error: +

+ + + + +
EBADFThe underlying OS file descriptor is invalid. +
EINTRThe current thread was interrupted by +st_thread_interrupt().
ETIMEThe timeout occurred without any I/O +becoming ready.
+

+

Description
+This function returns as soon as I/O is ready on the named file +descriptor object or the specified amount of time expires. The +how parameter should be set to the I/O events (readable, +writable, exception, or some combination) that the caller is interested +in. If the value of timeout is ST_UTIME_NO_TIMEOUT +(-1), this function blocks until a requested I/O event occurs +or until the call is interrupted by st_thread_interrupt().

+Despite having an interface like poll(2), this function uses +the same event notification mechanism as the rest of the library. For +instance if an alternative event nofication mechanism was set using st_set_eventsys(), this function uses that +mechanism to check for events.

+Note: if kqueue(2) is used as an alternative event +notification mechanism (see st_set_eventsys()), the POLLPRI +event flag is not supported and st_netfd_poll() will return an error +if it's set (errno will be set to EINVAL). +

+

+

+ +

st_accept()

+ +Accepts a connection on a specified file descriptor object. +

+

Syntax
+ +
+#include <st.h>
+
+st_netfd_t st_accept(st_netfd_t fd, struct sockaddr *addr, int *addrlen,
+                     st_utime_t timeout);
+
+

+

Parameters
+st_accept() has the following parameters:

+fd

+A file descriptor object identifier (see +st_netfd_t) representing the rendezvous socket +on which the caller is willing to accept new connections. This object has been +created from a valid listening socket by +st_netfd_open() or +st_netfd_open_socket().

+addr

+If this value is non-zero, it is a result parameter that is filled +in with the address of the connecting entity, as known to the communications +layer (see accept(3)).

+addrlen

+This parameter should initially contain the amount of space pointed to by +addr; on return it will contain the actual length (in bytes) of the +address returned (see accept(3)).

+timeout

+A value of type st_utime_t specifying the time +limit in microseconds for completion of the accept operation. +Note that timeouts are measured since the +last context switch. +

+

Returns
+Upon successful completion, a new file descriptor object identifier +representing the newly accepted connection is returned. Otherwise, +NULL is returned and errno is set to indicate the error. +Possible errno values are the same as set by the accept(3) +call with two exceptions:

+ + + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
ETIMEThe timeout occurred and no pending +connection was accepted.
+

+

Description
+This function accepts the first connection from the queue of pending +connections and creates a new file descriptor object for the newly +accepted connection. The rendezvous socket can still be used to accept +more connections.

+st_accept() blocks the calling thread until either a new connection +is successfully accepted or an error occurs. If no pending connection can +be accepted before the time limit, this function returns NULL +and sets errno to ETIME. +

+

+

+ +

st_connect()

+ +Initiates a connection on a specified file descriptor object. +

+

Syntax
+ +
+#include <st.h>
+
+int st_connect(st_netfd_t fd, struct sockaddr *addr, int addrlen,
+               st_utime_t timeout);
+
+

+

Parameters
+st_connect() has the following parameters:

+fd

+A file descriptor object identifier (see +st_netfd_t) representing a socket.

+addr

+A pointer to the address of the peer to which the socket is to be connected. +

+addrlen

+This parameter specifies the amount of space pointed to by addr. +

+timeout

+A value of type st_utime_t specifying the time +limit in microseconds for completion of the connect operation. +Note that timeouts are measured since the +last context switch. +

+

Returns
+Upon successful completion, a value of 0 is returned. +Otherwise, a value of -1 is returned and errno is set +to indicate the error. Possible errno values are the same as set +by the connect(3) call with two exceptions:

+ + + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
ETIMEThe timeout occurred and connection setup +was not completed.
+

+

Description
+This function is usually invoked on a file descriptor object representing +a TCP socket. Upon completion it establishes a TCP connection to the peer. +If the underlying OS socket is not bound, it will be bound to an arbitrary +local address (see connect(3)).

+st_connect() blocks the calling thread until either the connection +is successfully established or an error occurs. If the connection setup +cannot complete before the specified time limit, this function fails with +errno set to ETIME. +

+

+

+ +

st_read()

+ +Reads data from a specified file descriptor object. +

+

Syntax
+ +
+#include <st.h>
+
+ssize_t st_read(st_netfd_t fd, void *buf, size_t nbyte, st_utime_t timeout);
+
+

+

Parameters
+st_read() has the following parameters:

+fd

+A file descriptor object identifier (see +st_netfd_t).

+timeout

+A value of type st_utime_t specifying the time +limit in microseconds for completion of the read operation. +Note that timeouts are measured since the +last context switch. +

+

Returns
+On success a non-negative integer indicating the number of bytes actually +read is returned (a value of 0 means the network connection is +closed or end of file is reached). Otherwise, a value of -1 is +returned and errno is set to indicate the error. +Possible errno values are the same as set by the read(2) +call with two exceptions:

+ + + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
ETIMEThe timeout occurred and no data was read. +
+

+

Description
+This function blocks the calling thread until it encounters an end-of-stream +indication, some positive number of bytes (but no more than nbyte +bytes) are read in, a timeout occurs, or an error occurs. +

+

+

+ +

st_read_fully()

+ +Reads the specified amount of data in full from a file descriptor object. +

+

Syntax
+ +
+#include <st.h>

+A value of type st_utime_t specifying the +inactivity timeout (in microseconds). +Note that timeouts are measured since the +last context switch. +

+

Returns
+On success a non-negative integer indicating the number of bytes actually +read is returned (a value less than nbyte means the network +connection is closed or end of file is reached). Otherwise, a value of +-1 is returned and errno is set to indicate the error. +Possible errno values are the same as set by the read(2) +call with two exceptions:

+ + + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
ETIMEThe timeout occurred. +
+

+

Description
+This function blocks the calling thread until the specified amount of data +is read in full, it encounters an end-of-stream indication, a timeout occurs, +or an error occurs. +

+

+

+ +

st_read_resid()

+ +Reads the specified amount of data in full from a file descriptor object. +

+

Syntax
+ +

+Otherwise, a value of -1 is returned, *resid is non-zero, +and errno is set to indicate the error. +Possible errno values are the same as set by the read(2) +call with two exceptions:

+ + + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
ETIMEThe timeout occurred. +
+

+

Description
+This function blocks the calling thread until the specified amount of data +is read in full, it encounters an end-of-stream indication, a timeout occurs, +or an error occurs. It differs from st_read_fully() only in that +it allows the caller to know how many bytes were transferred before an error +occurred. +

+

+

+ +

st_readv()

+ +Reads data from a specified file descriptor object into multiple buffers. +

+

Syntax
+ +
+#include <st.h>

Otherwise, a value of -1 is +returned and errno is set to indicate the error. +Possible errno values are the same as set by the readv(2) +call with two exceptions:

+ + + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
ETIMEThe timeout occurred and no data was read. +
+

+

Description
+This function blocks the calling thread until it encounters an end-of-stream +indication, some positive number of bytes (but no more than fit in the buffers) +are read in, a timeout occurs, or an error occurs. +

+

+

+ +

st_readv_resid()

+ +Reads the specified amount of data in full from a file descriptor object +into multiple buffers. +

+

Syntax
+ +
+#include <st.h>
+
+int st_readv_resid(st_netfd_t fd, struct iovec **iov, int *iov_size,
+		   st_utime_t timeout);
+
+

+

Parameters
+st_readv_resid() has the following parameters:

+fd

+A file descriptor object identifier (see +st_netfd_t).

+iov

+A pointer to an array of iovec structures. +On entry, the iovecs identify the buffers for holding the data read in. +On return, the incomplete iovecs. +This function modifies both the pointer and the array to which it points.

+iov_size

+A pointer to a number of iovec structures. +On entry, the number of iovec structures pointed to by *iov. +On return, the number of incomplete or unused iovec structures. +(A non-zero returned value means some but not all of the data was read.)

+timeout

+A value of type st_utime_t specifying the +inactivity timeout (in microseconds). +Note that timeouts are measured since the +last context switch. +

+

Returns
+On success, zero is returned. *iov_size may be zero, indicating +a complete read, or non-zero, indicating the network connection is +closed or end of file is reached. *iov points to the first +iovec after the end of the original array on a complete read, or to the +first incomplete iovec on an incomplete read. +

+Otherwise, a value of -1 is returned, *iov_size is non-zero, +and errno is set to indicate the error. *iov points to the +first unused iovec. +Possible errno values are the same as set by the readv(2) +call with two exceptions:

+ + + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
ETIMEThe timeout occurred. +
+

All of the iovecs before *iov are modified such that +iov_base points to the end of the original buffer and +iov_len is zero. +

+

Description
+This function blocks the calling thread until the specified amount of data +is read in full, it encounters an end-of-stream indication, a timeout occurs, +or an error occurs. Like st_read_resid() it blocks the thread until +all of the requested data is read or an error occurs. Use +st_readv() to read up to the requested amount of data. +

+

+

+ +

st_write()

+ +Writes a buffer of data to a specified file descriptor object. +

+ + + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
ETIMEThe timeout occurred. +
+

+

Description
+This function blocks the calling thread until all the data is written, +a timeout occurs, or the write operation fails. The return value is equal to +either nbyte (on success) or -1 (on failure). Note that if +st_write() returns -1, some data (less than nbyte +bytes) may have been written before an error occurred. +

+

+

+ +

st_write_resid()

+ +Writes a buffer of data to a specified file descriptor object. +

+

Syntax
+ +

+ + + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
ETIMEThe timeout occurred. +
+

+

Description
+This function blocks the calling thread until all the data is written, +a timeout occurs, or the write operation fails. It differs from +st_write() only in that it allows the caller to know how many bytes +were transferred before an error occurred. +

+

+

+ +

st_writev()

+ +Writes data to a specified file descriptor object from multiple buffers. +

+

Syntax
+ +
+#include <st.h>
+

+

+

Description
+This function blocks the calling thread until all the data is written, +a timeout occurs, or the write operation fails. The return value is equal to +either the sum of all the buffer lengths (on success) or -1 (on +failure). Note that if st_writev() returns -1, part of the +data may have been written before an error occurred. +

+

+

+ +

st_writev_resid()

+ +Writes multiple buffers of data to a specified file descriptor object. +

+

+

+

+ +

st_recvfrom()

+ +Receives bytes from a file descriptor object and stores the sending peer's +address. +

+

Syntax
+ +
+#include <st.h>

+timeout

+A value of type st_utime_t specifying the time +limit in microseconds for completion of the receive operation. +Note that timeouts are measured since the +last context switch. +

+

Returns
+On success a non-negative integer indicating the length of the received +message in bytes is returned. Otherwise, a value of -1 is returned +and errno is set to indicate the error. Possible errno +values are the same as set by the recvfrom(3) call with two +exceptions:

+ + + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
ETIMEThe timeout occurred and no data was received. +
+

+

Description
+This function receives up to a specified number of bytes from the specified +file descriptor object representing a UDP socket.

+st_recvfrom() blocks the calling thread until one or more bytes are +transferred, a timeout has occurred, or there is an error. No more than +len bytes will be transferred. +

+

+

+ +

st_sendto()

+ +Sends bytes to a specified destination. +

+

Syntax

ETIMEThe timeout occurred and no data was sent. +
+

+

Description
+This function sends a specified number of bytes from a file descriptor +object representing a UDP socket to the specified destination address. +If no buffer space is available at the underlying OS socket to hold the +message to be transmitted, then st_sendto() blocks the calling +thread until the space becomes available, a timeout occurs, or an error +occurs. +

+

+

+ +

st_recvmsg()

+ +Receives a message from a file descriptor object. +

+

+ + + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
ETIMEThe timeout occurred and no data was received. +
+

+

Description
+This function receives bytes from the specified file descriptor object +representing a UDP socket. The operation is controlled by the in/out +msg parameter.

+st_recvmsg() blocks the calling thread until one or more bytes are +transferred, a timeout has occurred, or there is an error. +

+

+

+ +

st_sendmsg()

+ +Sends a message to a file descriptor object. +

+

Syntax
+ +
+#include <st.h>
+

EINTRThe current thread was interrupted by +st_thread_interrupt().
ETIMEThe timeout occurred and no data was sent. +
+

+

Description
+This function sends bytes to a file descriptor object representing a UDP +socket. The operation is controlled by the msg parameter. +If no buffer space is available at the underlying OS socket to hold the +message to be transmitted, then st_sendmsg() blocks the calling +thread until the space becomes available, a timeout occurs, or an error +occurs. +

+

+

+ +

st_open()

+ +Opens a file for reading, writing, or both. +

+

Syntax
+ +
+#include <st.h>
+
+st_netfd_t st_open(const char *path, int oflags, mode_t mode);
+
+

+

Parameters
+st_open() has the following parameters:

+path

+The pathname of the file to be opened.

+oflags

+File status flags. These are the same flags that are used by the +open(2) system call.

+mode

+Access permission bits of the file mode, if the file is created when +O_CREAT is set in oflags (see open(2)). +

+

Returns
+Upon successful completion, a new file descriptor object identifier is +returned. Otherwise, NULL is returned and errno is set +to indicate the error. +

+

Description
+This function creates a new file descriptor object of type +st_netfd_t for the file with the pathname +path. This object can be freed by +st_netfd_free() or +st_netfd_close().

+The primary purpose of this function is to open FIFOs (named pipes) or +other special files in order to create an end point of communication. +However, it can be used on regular files as well.

+Among other things, this function always sets a non-blocking flag on the +underlying OS file descriptor, so there is no need to include that flag in +oflags. +

+

+

+ +

st_poll()

+ +Detects when I/O is ready for a set of OS file descriptors. +

+

Syntax
+ +
+#include <st.h>
+
+int st_poll(struct pollfd *pds, int npds, st_utime_t timeout);
+
+

+

Parameters
+st_poll() has the following parameters:

+pds

+A pointer to an array of pollfd structures (see poll(2)). +

+npds

+The number of elements in the pds array.

+timeout

+A value of type st_utime_t specifying the +amount of time in microseconds the call will block waiting for I/O +to become ready. If this time expires without any I/O becoming ready, +st_poll() returns zero. +Note that timeouts are measured since the +last context switch. +

+

Returns
+Upon successful completion, a non-negative value is returned. A positive +value indicates the total number of OS file descriptors in pds +that have events. A value of 0 indicates that the call timed out. +Upon failure, a value of -1 is returned and errno is set +to indicate the error:

+ + +
EINTRThe current thread was interrupted by +st_thread_interrupt().
+

+If an alternative event notification mechanism has been set by +st_set_eventsys(), other values of +errno could be set upon failure as well. The values +depend on the specific mechanism in use. +

+

Description
+This function returns as soon as I/O is ready on one or more of the specified +OS file descriptors. A count of the number of ready descriptors is returned +unless a timeout occurs, in which case zero is returned.

+The pollfd structure is defined in the poll.h header file +and contains the following members:

+

+    int fd;             /* OS file descriptor */
+    short events;       /* requested events   */
+    short revents;      /* returned events    */
+
+The events field should be set to the I/O events (readable, +writable, exception, or some combination) that the caller is interested in. +On return, the revents field is set to indicate what kind of I/O +is ready on the respective descriptor.

+The events and revents fields are constructed by OR-ing +any combination of the following event flags (defined in poll.h): +

+ + + + + + +
POLLINfd is readable.
POLLOUTfd is is writable.
POLLPRIfd has an exception condition.
POLLNVALfd is bad.
+

+The POLLNVAL flag is only valid in the revents field; +it is not used in the events field.

+Despite having an interface like poll(2), this function uses +the same event notification mechanism as the rest of the library. For +instance if an alternative event nofication mechanism was set using st_set_eventsys(), this function uses that +mechanism to check for events.

+Note that unlike the poll(2) call, this function has the +timeout parameter expressed in microseconds. If the value of +timeout is ST_UTIME_NO_TIMEOUT +(-1), this function blocks until a requested I/O +event occurs or until the call is interrupted by +st_thread_interrupt(). +

+Note: if kqueue(2) is used as an alternative event +notification mechanism (see st_set_eventsys()), the POLLPRI +event flag is not supported and st_poll() will return an error +if it's set (errno will be set to EINVAL). +

+

+

+ + +

Program Structure

+ +

+Generally, the following steps should be followed when writing an application +using the State Threads library: +

+

    +
  1. Configure the library by calling these pre-init functions, if desired. + +
    2. +

    +

  2. Initialize the library by calling st_init().
    3. +

    +

  3. Configure the library by calling these post-init functions, if desired. + +
    4. +

    +

  4. Create resources that will be shared among different processes: + create and bind listening sockets (see socket(3), + bind(3), listen(3), + st_netfd_open_socket(), and possibly + st_netfd_serialize_accept()), + create shared memory segments, inter-process communication (IPC) + channels and synchronization primitives (if any).
    5. +

    +

  5. Create several processes via fork(2). The parent process should + either exit or become a "watchdog" (e.g., it starts a new process when + an existing one crashes, does a cleanup upon application termination, + etc.).
    6. +

    +

  6. In each child process create a pool of threads (see + st_thread_create()) to handle user + connections. Each thread in the pool may accept client connections + (st_accept()), connect to other servers + (st_connect()), perform various network I/O + (st_read(), st_write(), etc.).
    7. +
+

+Note that only State Threads library I/O functions should +be used for a network I/O: any other I/O calls may block the calling process +indefinitely. For example, standard I/O functions (fgets(3), +fread(3), fwrite(3), fprintf(3), etc.) call +read(2) and write(2) directly and therefore should not be +used on sockets or pipes. +

+Also note that for short timeouts to work the program +should do context switches (for example by calling +st_usleep()) on a regular basis. +

+

+

+ + +

List of Blocking Functions

+ +

+The thread context switch (process state change) can only happen +in a well-known set of blocking functions. +Only the following functions can block the calling thread: +

+

+
st_thread_join()
+
st_sleep()
+

State Threads for Internet Applications

+

Introduction

+

+State Threads is an application library which provides a +foundation for writing fast and highly scalable Internet Applications +on UNIX-like platforms. It combines the simplicity of the multithreaded +programming paradigm, in which one thread supports each simultaneous +connection, with the performance and scalability of an event-driven +state machine architecture.

+ +

1. Definitions

+

+ +

1.1 Internet Applications

+ +

+An Internet Application (IA) is either a server or client network +application that accepts connections from clients and may or may not +connect to servers. In an IA the arrival or departure of network data +often controls processing (that is, IA is a data-driven application). +For each connection, an IA does some finite amount of work +involving data exchange with its peer, where its peer may be either +a client or a server. +The typical transaction steps of an IA are to accept a connection, +read a request, do some finite and predictable amount of work to +process the request, then write a response to the peer that sent the +request. One example of an IA is a Web server; +the most general example of an IA is a proxy server, because it both +accepts connections from clients and connects to other servers.

+

+We assume that the performance of an IA is constrained by available CPU +cycles rather than network bandwidth or disk I/O (that is, CPU +is a bottleneck resource). +

+ + +

1.2 Performance and Scalability

+ +

+The performance of an IA is usually evaluated as its +throughput measured in transactions per second or bytes per second (one +can be converted to the other, given the average transaction size). There are +several benchmarks that can be used to measure throughput of Web serving +applications for specific workloads (such as +SPECweb96, +WebStone, +WebBench). +Although there is no common definition for scalability, in general it +expresses the ability of an application to sustain its performance when some +external condition changes. For IAs this external condition is either the +number of clients (also known as "users," "simultaneous connections," or "load +generators") or the underlying hardware system size (number of CPUs, memory +size, and so on). Thus there are two types of scalability: load +scalability and system scalability, respectively. +

+The figure below shows how the throughput of an idealized IA changes with +the increasing number of clients (solid blue line). Initially the throughput +grows linearly (the slope represents the maximal throughput that one client +can provide). Within this initial range, the IA is underutilized and CPUs are +partially idle. Further increase in the number of clients leads to a system +saturation, and the throughput gradually stops growing as all CPUs become fully +utilized. After that point, the throughput stays flat because there are no +more CPU cycles available. +In the real world, however, each simultaneous connection +consumes some computational and memory resources, even when idle, and this +overhead grows with the number of clients. Therefore, the throughput of the +real world IA starts dropping after some point (dashed blue line in the figure +below). The rate at which the throughput drops depends, among other things, on +application design. +

+We say that an application has a good load scalability if it can +sustain its throughput over a wide range of loads. +Interestingly, the SPECweb99 +benchmark somewhat reflects the Web server's load scalability because it +measures the number of clients (load generators) given a mandatory minimal +throughput per client (that is, it measures the server's capacity). +This is unlike SPECweb96 and +other benchmarks that use the throughput as their main metric (see the figure +below). +

+

+

+System scalability is the ability of an application to sustain its +performance per hardware unit (such as a CPU) with the increasing number of +these units. In other words, good system scalability means that doubling the +number of processors will roughly double the application's throughput (dashed +green line). We assume here that the underlying operating system also scales +well. Good system scalability allows you to initially run an application on +the smallest system possible, while retaining the ability to move that +application to a larger system if necessary, without excessive effort or +expense. That is, an application need not be rewritten or even undergo a +major porting effort when changing system size. +

+Although scalability and performance are more important in the case of server +IAs, they should also be considered for some client applications (such as +benchmark load generators). +

+ + +

1.3 Concurrency

+ +

+Concurrency reflects the parallelism in a system. The two unrelated types +are virtual concurrency and real concurrency. +

    +
  • Virtual (or apparent) concurrency is the number of simultaneous +connections that a system supports. +

    +
  • Real concurrency is the number of hardware devices, including +CPUs, network cards, and disks, that actually allow a system to perform +tasks in parallel. +
+

+An IA must provide virtual concurrency in order to serve many users +simultaneously. +To achieve maximum performance and scalability in doing so, the number of +programming entities than an IA creates to be scheduled by the OS kernel +should be +kept close to (within an order of magnitude of) the real concurrency found on +the system. These programming entities scheduled by the kernel are known as +kernel execution vehicles. Examples of kernel execution vehicles +include Solaris lightweight processes and IRIX kernel threads. +In other words, the number of kernel execution vehicles should be dictated by +the system size and not by the number of simultaneous connections. +

+ +

2. Existing Architectures

+

+There are a few different architectures that are commonly used by IAs. +These include the Multi-Process, +Multi-Threaded, and Event-Driven State Machine +architectures. +

+ +

2.1 Multi-Process Architecture

+ +

+In the Multi-Process (MP) architecture, an individual process is +dedicated to each simultaneous connection. +A process performs all of a transaction's initialization steps +and services a connection completely before moving on to service +a new connection. +

+User sessions in IAs are relatively independent; therefore, no +synchronization between processes handling different connections is +necessary. Because each process has its own private address space, +this architecture is very robust. If a process serving one of the connections +crashes, the other sessions will not be affected. However, to serve many +concurrent connections, an equal number of processes must be employed. +Because processes are kernel entities (and are in fact the heaviest ones), +the number of kernel entities will be at least as large as the number of +concurrent sessions. On most systems, good performance will not be achieved +when more than a few hundred processes are created because of the high +context-switching overhead. In other words, MP applications have poor load +scalability. +

+On the other hand, MP applications have very good system scalability, because +no resources are shared among different processes and there is no +synchronization overhead. +

+The Apache Web Server 1.x ([Reference 1]) uses the MP +architecture on UNIX systems. +

+ +

2.2 Multi-Threaded Architecture

+ +

+In the Multi-Threaded (MT) architecture, multiple independent threads +of control are employed within a single shared address space. Like a +process in the MP architecture, each thread performs all of a +transaction's initialization steps and services a connection completely +before moving on to service a new connection. +

+Many modern UNIX operating systems implement a many-to-few model when +mapping user-level threads to kernel entities. In this model, an +arbitrarily large number of user-level threads is multiplexed onto a +lesser number of kernel execution vehicles. Kernel execution +vehicles are also known as virtual processors. Whenever a user-level +thread makes a blocking system call, the kernel execution vehicle it is using +will become blocked in the kernel. If there are no other non-blocked kernel +execution vehicles and there are other runnable user-level threads, a new +kernel execution vehicle will be created automatically. This prevents the +application from blocking when it can continue to make useful forward +progress. +

+Because IAs are by nature network I/O driven, all concurrent sessions block on +network I/O at various points. As a result, the number of virtual processors +created in the kernel grows close to the number of user-level threads +(or simultaneous connections). When this occurs, the many-to-few model +effectively degenerates to a one-to-one model. Again, like in +the MP architecture, the number of kernel execution vehicles is dictated by +the number of simultaneous connections rather than by number of CPUs. This +reduces an application's load scalability. However, because kernel threads +(lightweight processes) use fewer resources and are more light-weight than +traditional UNIX processes, an MT application should scale better with load +than an MP application. +

+Unexpectedly, the small number of virtual processors sharing the same address +space in the MT architecture destroys an application's system scalability +because of contention among the threads on various locks. Even if an +application itself is carefully +optimized to avoid lock contention around its own global data (a non-trivial +task), there are still standard library functions and system calls +that use common resources hidden from the application. For example, +on many platforms thread safety of memory allocation routines +(malloc(3), free(3), and so on) is achieved by using a single +global lock. Another example is a per-process file descriptor table. +This common resource table is shared by all kernel execution vehicles within +the same process and must be protected when one modifies it via +certain system calls (such as open(2), close(2), and so on). +In addition to that, maintaining the caches coherent +among CPUs on multiprocessor systems hurts performance when different threads +running on different CPUs modify data items on the same cache line. +

+In order to improve load scalability, some applications employ a different +type of MT architecture: they create one or more thread(s) per task +rather than one thread per connection. For example, one small group +of threads may be responsible for accepting client connections, another +for request processing, and yet another for serving responses. The main +advantage of this architecture is that it eliminates the tight coupling +between the number of threads and number of simultaneous connections. However, +in this architecture, different task-specific thread groups must share common +work queues that must be protected by mutual exclusion locks (a typical +producer-consumer problem). This adds synchronization overhead that causes an +application to perform badly on multiprocessor systems. In other words, in +this architecture, the application's system scalability is sacrificed for the +sake of load scalability. +

+Of course, the usual nightmares of threaded programming, including data +corruption, deadlocks, and race conditions, also make MT architecture (in any +form) non-simplistic to use. +

+ + +

2.3 Event-Driven State Machine Architecture

+ +

+In the Event-Driven State Machine (EDSM) architecture, a single process +is employed to concurrently process multiple connections. The basics of this +architecture are described in Comer and Stevens +[Reference 2]. +The EDSM architecture performs one basic data-driven step associated with +a particular connection at a time, thus multiplexing many concurrent +connections. The process operates as a state machine that receives an event +and then reacts to it. +

+In the idle state the EDSM calls select(2) or poll(2) to +wait for network I/O events. When a particular file descriptor is ready for +I/O, the EDSM completes the corresponding basic step (usually by invoking a +handler function) and starts the next one. This architecture uses +non-blocking system calls to perform asynchronous network I/O operations. +For more details on non-blocking I/O see Stevens +[Reference 3]. +

+To take advantage of hardware parallelism (real concurrency), multiple +identical processes may be created. This is called Symmetric Multi-Process +EDSM and is used, for example, in the Zeus Web Server +([Reference 4]). To more efficiently multiplex disk I/O, +special "helper" processes may be created. This is called Asymmetric +Multi-Process EDSM and was proposed for Web servers by Druschel +and others [Reference 5]. +

+EDSM is probably the most scalable architecture for IAs. +Because the number of simultaneous connections (virtual concurrency) is +completely decoupled from the number of kernel execution vehicles (processes), +this architecture has very good load scalability. It requires only minimal +user-level resources to create and maintain additional connection. +

+Like MP applications, Multi-Process EDSM has very good system scalability +because no resources are shared among different processes and there is no +synchronization overhead. +

+Unfortunately, the EDSM architecture is monolithic rather than based on the +concept of threads, so new applications generally need to be implemented from +the ground up. In effect, the EDSM architecture simulates threads and their +stacks the hard way. +

+ + +

3. State Threads Library

+ +

+The State Threads library combines the advantages of all of the above +architectures. The interface preserves the programming simplicity of thread +abstraction, allowing each simultaneous connection to be treated as a separate +thread of execution within a single process. The underlying implementation is +close to the EDSM architecture as the state of each particular concurrent +session is saved in a separate memory segment. +

+ +

3.1 State Changes and Scheduling

+

+The state of each concurrent session includes its stack environment +(stack pointer, program counter, CPU registers) and its stack. Conceptually, +a thread context switch can be viewed as a process changing its state. There +are no kernel entities involved other than processes. +Unlike other general-purpose threading libraries, the State Threads library +is fully deterministic. The thread context switch (process state change) can +only happen in a well-known set of functions (at I/O points or at explicit +synchronization points). As a result, process-specific global data does not +have to be protected by mutual exclusion locks in most cases. The entire +application is free to use all the static variables and non-reentrant library +functions it wants, greatly simplifying programming and debugging while +increasing performance. This is somewhat similar to a co-routine model +(co-operatively multitasked threads), except that no explicit yield is needed +-- +sooner or later, a thread performs a blocking I/O operation and thus surrenders +control. All threads of execution (simultaneous connections) have the +same priority, so scheduling is non-preemptive, like in the EDSM architecture. +Because IAs are data-driven (processing is limited by the size of network +buffers and data arrival rates), scheduling is non-time-slicing. +

+Only two types of external events are handled by the library's +scheduler, because only these events can be detected by +select(2) or poll(2): I/O events (a file descriptor is ready +for I/O) and time events +(some timeout has expired). However, other types of events (such as +a signal sent to a process) can also be handled by converting them to I/O +events. For example, a signal handling function can perform a write to a pipe +(write(2) is reentrant/asynchronous-safe), thus converting a signal +event to an I/O event. +

+To take advantage of hardware parallelism, as in the EDSM architecture, +multiple processes can be created in either a symmetric or asymmetric manner. +Process management is not in the library's scope but instead is left up to the +application. +

+There are several general-purpose threading libraries that implement a +many-to-one model (many user-level threads to one kernel execution +vehicle), using the same basic techniques as the State Threads library +(non-blocking I/O, event-driven scheduler, and so on). For an example, see GNU +Portable Threads ([Reference 6]). Because they are +general-purpose, these libraries have different objectives than the State +Threads library. The State Threads library is not a general-purpose +threading library, +but rather an application library that targets only certain types of +applications (IAs) in order to achieve the highest possible performance and +scalability for those applications. +

+ +

3.2 Scalability

+

+State threads are very lightweight user-level entities, and therefore creating +and maintaining user connections requires minimal resources. An application +using the State Threads library scales very well with the increasing number +of connections. +

+On multiprocessor systems an application should create multiple processes +to take advantage of hardware parallelism. Using multiple separate processes +is the only way to achieve the highest possible system scalability. +This is because duplicating per-process resources is the only way to avoid +significant synchronization overhead on multiprocessor systems. Creating +separate UNIX processes naturally offers resource duplication. Again, +as in the EDSM architecture, there is no connection between the number of +simultaneous connections (which may be very large and changes within a wide +range) and the number of kernel entities (which is usually small and constant). +In other words, the State Threads library makes it possible to multiplex a +large number of simultaneous connections onto a much smaller number of +separate processes, thus allowing an application to scale well with both +the load and system size. +

+ +

3.3 Performance

+

+Performance is one of the library's main objectives. The State Threads +library is implemented to minimize the number of system calls and +to make thread creation and context switching as fast as possible. +For example, per-thread signal mask does not exist (unlike +POSIX threads), so there is no need to save and restore a process's +signal mask on every thread context switch. This eliminates two system +calls per context switch. Signal events can be handled much more +efficiently by converting them to I/O events (see above). +

+ +

3.4 Portability

+

+The library uses the same general, underlying concepts as the EDSM +architecture, including non-blocking I/O, file descriptors, and +I/O multiplexing. These concepts are available in some form on most +UNIX platforms, making the library very portable across many +flavors of UNIX. There are only a few platform-dependent sections in the +source. +

+ +

3.5 State Threads and NSPR

+

+The State Threads library is a derivative of the Netscape Portable +Runtime library (NSPR) [Reference 7]. The primary goal of +NSPR is to provide a platform-independent layer for system facilities, +where system facilities include threads, thread synchronization, and I/O. +Performance and scalability are not the main concern of NSPR. The +State Threads library addresses performance and scalability while +remaining much smaller than NSPR. It is contained in 8 source files +as opposed to more than 400, but provides all the functionality that +is needed to write efficient IAs on UNIX-like platforms. +

Conclusion

+

+State Threads is an application library which provides a foundation for +writing Internet Applications. To summarize, it has the +following advantages: +

+

    +
  • It allows the design of fast and highly scalable applications. An +application will scale well with both load and number of CPUs. +

    +

  • It greatly simplifies application programming and debugging because, as a +rule, no mutual exclusion locking is necessary and the entire application is +free to use static variables and non-reentrant library functions. +
+

+The library's main limitation: +

+

    +
  • All I/O operations on sockets must use the State Thread library's I/O +functions because only those functions perform thread scheduling and prevent +the application's processes from blocking. +

This improves performance when there is a large number +of sleeping threads, since insertion into a heap takes O(log N) time +while insertion into a sorted list takes O(N) time. For example, in +one test 1000 threads were created, each thread called st_usleep() +with a random time interval, and then all the threads where +immediately interrupted and joined before the sleeps had a chance to +finish. The whole process was repeated 1000 times, for a total of a +million sleep queue insertions and removals. With the old list-based +sleep queue, this test took 100 seconds; now it takes only 12 seconds. + +Heap data structures are typically based on dynamically resized +arrays. However, since the existing ST code base was very nicely +structured around linking the thread objects into pointer-based lists +without the need for any auxiliary data structures, implementing the +heap using a similar nodes-and-pointers based approach seemed more +appropriate for ST than introducing a separate array. + +Thus, the new ST timeout heap works by organizing the existing +_st_thread_t objects in a balanced binary tree, just as they were +previously organized into a doubly-linked, sorted list. The global +_ST_SLEEPQ variable, formerly a linked list head, is now simply a +pointer to the root of this tree, and the root node of the tree is the +thread with the earliest timeout. Each thread object has two child +pointers, "left" and "right", pointing to threads with later timeouts. + +Each node in the tree is numbered with an integer index, corresponding +to the array index in an array-based heap, and the tree is kept fully +balanced and left-adjusted at all times. In other words, the tree +consists of any number of fully populated top levels, followed by a +single bottom level which may be partially populated, such that any +existing nodes form a contiguous block to the left and the spaces for +missing nodes form a contiguous block to the right. For example, if +there are nine threads waiting for a timeout, they are numbered and +arranged in a tree exactly as follows: + + 1 + / \ + 2 3 + / \ / \ + 4 5 6 7 + / \ + 8 9 + +Each node has either no children, only a left child, or both a left +and a right child. Children always time out later than their parents +(this is called the "heap invariant"), but when a node has two +children, their mutual order is unspecified - the left child may time +out before or after the right child. If a node is numbered N, its +left child is numbered 2N, and its right child is numbered 2N+1. + +There is no pointer from a child to its parent; all pointers point +downward. Additions and deletions both work by starting at the root +and traversing the tree towards the leaves, going left or right +according to the binary digits forming the index of the destination +node. As nodes are added or deleted, existing nodes are rearranged to +maintain the heap invariant. diff --git a/trunk/3rdparty/st-srs/event.c b/trunk/3rdparty/st-srs/event.c new file mode 100644 index 0000000000..142882a51e --- /dev/null +++ b/trunk/3rdparty/st-srs/event.c @@ -0,0 +1,1413 @@ +/* + * The contents of this file are subject to the Mozilla Public + * License Version 1.1 (the "License"); you may not use this file + * except in compliance with the License.

He wrote: +---------------------------------------- +Hello, + +This is a patch that enables programmatically dumping the stack of +every thread. This has been useful in debugging deadlocks, etc... +Our usage model is that the SIGUSR2 handler calls the new +_st_print_thread_stacks function, which dumps the stack for all +threads. A convenient feature is that for thread stacks that are the +same (which is common for application with a lot of worker threads +waiting for work), only one stack trace is printed, along with a +count of how many threads have that same stack. + +I use the glibc backtrace function to get the backtrace, and then use +popen to execute addr2line and convert memory addresses to file +names, function names, and line numbers. If glibc isn't available, +_st_print_thread_stacks just prints a warning. And this feature is +only available if DEBUG is turned on. + +We've found this feature extremely helpful when debugging. + +The patch can be a bit more robust (it assumes addr2line exists). +But I didn't want to go through the hassle of doing this, if the +StateThreads community doesn't want to use this patch. (In our +environment, addr2line will always be there.) + +Cheers, +Mike +---------------------------------------- +Invoking complex functions from a signal handler is not recommended, +plus this patch changes the behavior of existing API hooks.

(libavformat + * always returns refcounted AVPackets, and av_frame_get_buffer() allocates + * refcounted AVFrames.) + * - Receive output in a loop. Periodically call one of the avcodec_receive_*() + * functions and process their output: + * - For decoding, call avcodec_receive_frame(). On success, it will return + * an AVFrame containing uncompressed audio or video data. + * - For encoding, call avcodec_receive_packet(). On success, it will return + * an AVPacket with a compressed frame. + * Repeat this call until it returns AVERROR(EAGAIN) or an error. The + * AVERROR(EAGAIN) return value means that new input data is required to + * return new output. In this case, continue with sending input. For each + * input frame/packet, the codec will typically return 1 output frame/packet, + * but it can also be 0 or more than 1. + * + * At the beginning of decoding or encoding, the codec might accept multiple + * input frames/packets without returning a frame, until its internal buffers + * are filled. This situation is handled transparently if you follow the steps + * outlined above. + * + * In theory, sending input can result in EAGAIN - this should happen only if + * not all output was received. You can use this to structure alternative decode + * or encode loops other than the one suggested above. For example, you could + * try sending new input on each iteration, and try to receive output if that + * returns EAGAIN. + * + * End of stream situations. These require "flushing" (aka draining) the codec, + * as the codec might buffer multiple frames or packets internally for + * performance or out of necessity (consider B-frames). + * This is handled as follows: + * - Instead of valid input, send NULL to the avcodec_send_packet() (decoding) + * or avcodec_send_frame() (encoding) functions. This will enter draining + * mode. + * - Call avcodec_receive_frame() (decoding) or avcodec_receive_packet() + * (encoding) in a loop until AVERROR_EOF is returned. The functions will + * not return AVERROR(EAGAIN), unless you forgot to enter draining mode. + * - Before decoding can be resumed again, the codec has to be reset with + * avcodec_flush_buffers(). + * + * Using the API as outlined above is highly recommended. But it is also + * possible to call functions outside of this rigid schema. For example, you can + * call avcodec_send_packet() repeatedly without calling + * avcodec_receive_frame(). In this case, avcodec_send_packet() will succeed + * until the codec's internal buffer has been filled up (which is typically of + * size 1 per output frame, after initial input), and then reject input with + * AVERROR(EAGAIN). Once it starts rejecting input, you have no choice but to + * read at least some output. + * + * Not all codecs will follow a rigid and predictable dataflow; the only + * guarantee is that an AVERROR(EAGAIN) return value on a send/receive call on + * one end implies that a receive/send call on the other end will succeed, or + * at least will not fail with AVERROR(EAGAIN). In general, no codec will + * permit unlimited buffering of input or output. + * + * This API replaces the following legacy functions: + * - avcodec_decode_video2() and avcodec_decode_audio4(): + * Use avcodec_send_packet() to feed input to the decoder, then use + * avcodec_receive_frame() to receive decoded frames after each packet. + * Unlike with the old video decoding API, multiple frames might result from + * a packet. For audio, splitting the input packet into frames by partially + * decoding packets becomes transparent to the API user. You never need to + * feed an AVPacket to the API twice (unless it is rejected with AVERROR(EAGAIN) - then + * no data was read from the packet). + * Additionally, sending a flush/draining packet is required only once. + * - avcodec_encode_video2()/avcodec_encode_audio2(): + * Use avcodec_send_frame() to feed input to the encoder, then use + * avcodec_receive_packet() to receive encoded packets. + * Providing user-allocated buffers for avcodec_receive_packet() is not + * possible. + * - The new API does not handle subtitles yet. + * + * Mixing new and old function calls on the same AVCodecContext is not allowed, + * and will result in undefined behavior. + * + * Some codecs might require using the new API; using the old API will return + * an error when calling it. All codecs support the new API. + * + * A codec is not allowed to return AVERROR(EAGAIN) for both sending and receiving. This + * would be an invalid state, which could put the codec user into an endless + * loop. The API has no concept of time either: it cannot happen that trying to + * do avcodec_send_packet() results in AVERROR(EAGAIN), but a repeated call 1 second + * later accepts the packet (with no other receive/flush API calls involved). + * The API is a strict state machine, and the passage of time is not supposed + * to influence it. Some timing-dependent behavior might still be deemed + * acceptable in certain cases. But it must never result in both send/receive + * returning EAGAIN at the same time at any point. It must also absolutely be + * avoided that the current state is "unstable" and can "flip-flop" between + * the send/receive APIs allowing progress. For example, it's not allowed that + * the codec randomly decides that it actually wants to consume a packet now + * instead of returning a frame, after it just returned AVERROR(EAGAIN) on an + * avcodec_send_packet() call. + * @} + */ + +/** + * @defgroup lavc_core Core functions/structures. + * @ingroup libavc + * + * Basic definitions, functions for querying libavcodec capabilities, + *

(An + * implication is that this will prefer generic formats over opaque formats + * with arbitrary restrictions, if possible.) + * - Set the width/height fields to the coded frame size, rounded up to the + * API-specific minimum alignment. + * - Only _if_ the hwaccel requires a pre-allocated pool: set the initial_pool_size + * field to the number of maximum reference surfaces possible with the codec, + * plus 1 surface for the user to work (meaning the user can safely reference + * at most 1 decoded surface at a time), plus additional buffering introduced + * by frame threading.

An option can have a help text, a type and a range of possible + * values. Options may then be enumerated, read and written to. + * + * @section avoptions_implement Implementing AVOptions + * This section describes how to add AVOptions capabilities to a struct. + * + * All AVOptions-related information is stored in an AVClass. Therefore + * the first member of the struct should be a pointer to an AVClass describing it. + * The option field of the AVClass must be set to a NULL-terminated static array + * of AVOptions. Each AVOption must have a non-empty name, a type, a default + * value and for number-type AVOptions also a range of allowed values. It must + * also declare an offset in bytes from the start of the struct, where the field + * associated with this AVOption is located. Other fields in the AVOption struct + * should also be set when applicable, but are not required. + * + * The following example illustrates an AVOptions-enabled struct: + * @code + * typedef struct test_struct { + * const AVClass *class; + * int int_opt; + * char *str_opt; + * uint8_t *bin_opt; + * int bin_len; + * } test_struct; + * + * static const AVOption test_options[] = { + * { "test_int", "This is a test option of int type.", offsetof(test_struct, int_opt), + * AV_OPT_TYPE_INT, { .i64 = -1 }, INT_MIN, INT_MAX }, + * { "test_str", "This is a test option of string type.", offsetof(test_struct, str_opt), + * AV_OPT_TYPE_STRING }, + * { "test_bin", "This is a test option of binary type.", offsetof(test_struct, bin_opt), + * AV_OPT_TYPE_BINARY }, + * { NULL }, + * }; + * + * static const AVClass test_class = { + * .class_name = "test class", + * .item_name = av_default_item_name, + * .option = test_options, + * .version = LIBAVUTIL_VERSION_INT, + * }; + * @endcode + * + * Next, when allocating your struct, you must ensure that the AVClass pointer + * is set to the correct value. Then, av_opt_set_defaults() can be called to + * initialize defaults. After that the struct is ready to be used with the + * AVOptions API. + * + * When cleaning up, you may use the av_opt_free() function to automatically + * free all the allocated string and binary options. + * + * Continuing with the above example: + * + * @code + * test_struct *alloc_test_struct(void) + * { + * test_struct *ret = av_mallocz(sizeof(*ret)); + * ret->class = &test_class; + * av_opt_set_defaults(ret); + * return ret; + * } + * void free_test_struct(test_struct **foo) + * { + * av_opt_free(*foo); + * av_freep(foo); + * } + * @endcode + * + * @subsection avoptions_implement_nesting Nesting + * It may happen that an AVOptions-enabled struct contains another + * AVOptions-enabled struct as a member (e.g. AVCodecContext in + * libavcodec exports generic options, while its priv_data field exports + * codec-specific options). In such a case, it is possible to set up the + * parent struct to export a child's options. To do that, simply + * implement AVClass.child_next() and AVClass.child_class_next() in the + * parent struct's AVClass. + * Assuming that the test_struct from above now also contains a + * child_struct field: + * + * @code + * typedef struct child_struct { + * AVClass *class; + * int flags_opt; + * } child_struct; + * static const AVOption child_opts[] = { + * { "test_flags", "This is a test option of flags type.", + * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX }, + * { NULL }, + * }; + * static const AVClass child_class = { + * .class_name = "child class", + * .item_name = av_default_item_name, + * .option = child_opts, + * .version = LIBAVUTIL_VERSION_INT, + * }; + * + * void *child_next(void *obj, void *prev) + * { + * test_struct *t = obj; + * if (!prev && t->child_struct) + * return t->child_struct; + * return NULL + * } + * const AVClass child_class_next(const AVClass *prev) + * { + * return prev ? NULL : &child_class; + * } + * @endcode + * Putting child_next() and child_class_next() as defined above into + * test_class will now make child_struct's options accessible through + * test_struct (again, proper setup as described above needs to be done on + * child_struct right after it is created). + * + * From the above example it might not be clear why both child_next() + * and child_class_next() are needed. The distinction is that child_next() + * iterates over actually existing objects, while child_class_next() + * iterates over all possible child classes. E.g. if an AVCodecContext + * was initialized to use a codec which has private options, then its + * child_next() will return AVCodecContext.priv_data and finish + * iterating. OTOH child_class_next() on AVCodecContext.av_class will + * iterate over all available codecs with private options. + * + * @subsection avoptions_implement_named_constants Named constants + * It is possible to create named constants for options. Simply set the unit + * field of the option the constants should apply to a string and + * create the constants themselves as options of type AV_OPT_TYPE_CONST + * with their unit field set to the same string. + * Their default_val field should contain the value of the named + * constant. + * For example, to add some named constants for the test_flags option + * above, put the following into the child_opts array: + * @code + * { "test_flags", "This is a test option of flags type.", + * offsetof(child_struct, flags_opt), AV_OPT_TYPE_FLAGS, { .i64 = 0 }, INT_MIN, INT_MAX, "test_unit" }, + * { "flag1", "This is a flag with value 16", 0, AV_OPT_TYPE_CONST, { .i64 = 16 }, 0, 0, "test_unit" }, + * @endcode + * + * @section avoptions_use Using AVOptions + * This section deals with accessing options in an AVOptions-enabled struct. + * Such structs in FFmpeg are e.g. AVCodecContext in libavcodec or + * AVFormatContext in libavformat. + * + * @subsection avoptions_use_examine Examining AVOptions + * The basic functions for examining options are av_opt_next(), which iterates + * over all options defined for one object, and av_opt_find(), which searches + * for an option with the given name. + * + * The situation is more complicated with nesting. An AVOptions-enabled struct + * may have AVOptions-enabled children. Passing the AV_OPT_SEARCH_CHILDREN flag + * to av_opt_find() will make the function search children recursively. + * + * For enumerating there are basically two cases. The first is when you want to + * get all options that may potentially exist on the struct and its children + * (e.g. when constructing documentation). In that case you should call + * av_opt_child_class_next() recursively on the parent struct's AVClass. The + * second case is when you have an already initialized struct with all its + * children and you want to get all options that can be actually written or read + * from it. In that case you should call av_opt_child_next() recursively (and + * av_opt_next() on each result). + * + * @subsection avoptions_use_get_set Reading and writing AVOptions + * When setting options, you often have a string read directly from the + * user. In such a case, simply passing it to av_opt_set() is enough. For + * non-string type options, av_opt_set() will parse the string according to the + * option type. + * + * Similarly av_opt_get() will read any option type and convert it to a string + * which will be returned. Do not forget that the string is allocated, so you + * have to free it with av_free(). + * + * In some cases it may be more convenient to put all options into an + * AVDictionary and call av_opt_set_dict() on it. A specific case of this + * are the format/codec open functions in lavf/lavc which take a dictionary + * filled with option as a parameter. This makes it possible to set some options + * that cannot be set otherwise, since e.g. the input file format is not known + * before the file is actually opened. + */ + +enum AVOptionType{ + AV_OPT_TYPE_FLAGS, + AV_OPT_TYPE_INT, + AV_OPT_TYPE_INT64, + AV_OPT_TYPE_DOUBLE, + AV_OPT_TYPE_FLOAT, + AV_OPT_TYPE_STRING, + AV_OPT_TYPE_RATIONAL, + AV_OPT_TYPE_BINARY, ///< offset must point to a pointer immediately followed by an int for the length + AV_OPT_TYPE_DICT, + AV_OPT_TYPE_UINT64, + AV_OPT_TYPE_CONST, + AV_OPT_TYPE_IMAGE_SIZE, ///< offset must point to two consecutive integers + AV_OPT_TYPE_PIXEL_FMT, + AV_OPT_TYPE_SAMPLE_FMT, + AV_OPT_TYPE_VIDEO_RATE, ///< offset must point to AVRational + AV_OPT_TYPE_DURATION, + AV_OPT_TYPE_COLOR, + AV_OPT_TYPE_CHANNEL_LAYOUT, + AV_OPT_TYPE_BOOL, +}; + +/** + * AVOption + */ +typedef struct AVOption { + const char *name; + + /** + * short English help text + * @todo What about other languages? + */ + const char *help; + + /** + * The offset relative to the context structure where the option + * value is stored.

This is using the swr_alloc() function. + * @code + * SwrContext *swr = swr_alloc(); + * av_opt_set_channel_layout(swr, "in_channel_layout", AV_CH_LAYOUT_5POINT1, 0); + * av_opt_set_channel_layout(swr, "out_channel_layout", AV_CH_LAYOUT_STEREO, 0); + * av_opt_set_int(swr, "in_sample_rate", 48000, 0); + * av_opt_set_int(swr, "out_sample_rate", 44100, 0); + * av_opt_set_sample_fmt(swr, "in_sample_fmt", AV_SAMPLE_FMT_FLTP, 0); + * av_opt_set_sample_fmt(swr, "out_sample_fmt", AV_SAMPLE_FMT_S16, 0); + * @endcode + * + * The same job can be done using swr_alloc_set_opts() as well: + * @code + * SwrContext *swr = swr_alloc_set_opts(NULL, // we're allocating a new context + * AV_CH_LAYOUT_STEREO, // out_ch_layout + * AV_SAMPLE_FMT_S16, // out_sample_fmt + * 44100, // out_sample_rate + * AV_CH_LAYOUT_5POINT1, // in_ch_layout + * AV_SAMPLE_FMT_FLTP, // in_sample_fmt + * 48000, // in_sample_rate + * 0, // log_offset + * NULL); // log_ctx + * @endcode + * + * Once all values have been set, it must be initialized with swr_init(). If + * you need to change the conversion parameters, you can change the parameters + * using @ref AVOptions, as described above in the first example; or by using + * swr_alloc_set_opts(), but with the first argument the allocated context. + * You must then call swr_init() again. + * + * The conversion itself is done by repeatedly calling swr_convert(). + * Note that the samples may get buffered in swr if you provide insufficient + * output space or if sample rate conversion is done, which requires "future" + * samples. Samples that do not require future input can be retrieved at any + * time by using swr_convert() (in_count can be set to 0). + * At the end of conversion the resampling buffer can be flushed by calling + * swr_convert() with NULL in and 0 in_count. + * + * The samples used in the conversion process can be managed with the libavutil + * @ref lavu_sampmanip "samples manipulation" API, including av_samples_alloc() + * function used in the following example. + * + * The delay between input and output, can at any time be found by using + * swr_get_delay(). + * + * The following code demonstrates the conversion loop assuming the parameters + * from above and caller-defined functions get_input() and handle_output(): + * @code + * uint8_t **input; + * int in_samples; + * + * while (get_input(&input, &in_samples)) { + * uint8_t *output; + * int out_samples = av_rescale_rnd(swr_get_delay(swr, 48000) + + * in_samples, 44100, 48000, AV_ROUND_UP); + * av_samples_alloc(&output, NULL, 2, out_samples, + * AV_SAMPLE_FMT_S16, 0); + * out_samples = swr_convert(swr, &output, out_samples, + * input, in_samples); + * handle_output(output, out_samples); + * av_freep(&output); + * } + * @endcode + * + * When the conversion is finished, the conversion + * context and everything associated with it must be freed with swr_free(). + * A swr_close() function is also available, but it exists mainly for + * compatibility with libavresample, and is not required to be called. + * + * There will be no memory leak if the data is not completely flushed before + * swr_free(). + */ + +#include +#include "libavutil/channel_layout.h" +#include "libavutil/frame.h" +#include "libavutil/samplefmt.h" + +#include "libswresample/version.h" + +/** + * @name Option constants + * These constants are used for the @ref avoptions interface for lswr. + * @{ + * + */ + +#define SWR_FLAG_RESAMPLE 1 ///< Force resampling even if equal sample rate +//TODO use int resample ? +//long term TODO can we enable this dynamically? + +/** Dithering algorithms */ +enum SwrDitherType { + SWR_DITHER_NONE = 0, + SWR_DITHER_RECTANGULAR, + SWR_DITHER_TRIANGULAR, + SWR_DITHER_TRIANGULAR_HIGHPASS, + + SWR_DITHER_NS = 64, ///< not part of API/ABI + SWR_DITHER_NS_LIPSHITZ, + SWR_DITHER_NS_F_WEIGHTED, + SWR_DITHER_NS_MODIFIED_E_WEIGHTED, + SWR_DITHER_NS_IMPROVED_E_WEIGHTED, + SWR_DITHER_NS_SHIBATA, + SWR_DITHER_NS_LOW_SHIBATA, + SWR_DITHER_NS_HIGH_SHIBATA, + SWR_DITHER_NB, ///< not part of API/ABI +}; + +/** Resampling Engines */ +enum SwrEngine { + SWR_ENGINE_SWR, /**< SW Resampler */ + SWR_ENGINE_SOXR, /**< SoX Resampler */ + SWR_ENGINE_NB, ///< not part of API/ABI +}; + +/** Resampling Filter Types */ +enum SwrFilterType { + SWR_FILTER_TYPE_CUBIC, /**< Cubic */ + SWR_FILTER_TYPE_BLACKMAN_NUTTALL, /**< Blackman Nuttall windowed sinc */ + SWR_FILTER_TYPE_KAISER, /**< Kaiser windowed sinc */ +}; + +/** + * @} + */ + +/** + * The libswresample context.
