All notable changes to this project will be documented in this file.
The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.
- Support for s390x
buf
a new function that makes it possible to safely print arbitrary binary data- A new function,
sizeof
, which returns the size of an expression, similar tosizeof
in C - C style while loop support,
while ($a < 100) { $a++ }
- Using a BTF enum value will pull in the entire enum definition
- Add support of using positional params in unroll and increase the unroll limit to 100
- Support for piping scripts in via stdin
- Don't require <linux/types.h> if --btf is specified
- Silence errors about
modprobe
not being found - With --btf, do not use <linux/types.h> for resolving tracepoint defs
- Add environment variable, BPFTRACE_PERF_RB_PAGES, to tune perf ring buffer size
- Add --usdt-file-activation to activate usdt semaphores by file name
- Introduce
-k
and-kk
options. Emit a warning when a bpf helper returns an error - Add tuples to language
- Add support for listing struct/union/enum definitions using BTF
- Add libbpf build into in --info
- Add support for time units
us
andhz
for probeinterval
- Require C++17 and CMake 3.8 for building bpftrace
- Allow positional parameters in probe attachpoint definitions
- Only list uprobe and usdt probes when
-p
is given - Remove address space memory limit
- Drop LLVM 5 support
- Various big endian related fixes
- Type check the
cond
of if and ternary statements - Fix usdt reads in various architecture
- Attach to duplicated USDT markers
- Fix
KBUILD_MODNAME
- Fix
ntop()
not accepting tracepoint arguments - Fix attaching to usdt probes in multiple binaries
- Decrement usdt semaphore count after bpftrace execution
- Reduce high memory consumption when using usdt semaphore
- Remove registers that are not in struct pt_regs (x86-64)
Improved kprobes which are near zero overhead and use BTF to derive argument names and types:
bpftrace -e 'kfunc:fget { printf("fd %d\n", args->fd); }'
bpftrace can now demangle C++ symbols in binaries:
bpftrace -e 'uprobe:./a.out:"foo()" {printf("ok\n");}
Support for if else
has been added, making it possible to write:
if (cond) {
...
} else if (cond) {
...
}
Instead of:
if (cond) {
...
} else {
if (cond) {
...
}
}
Support for LLVM 9 and LLVM 10 has been added.
Docker images containing a static build are now available on quay.io.

This is a release to aid packaging. bpftrace has not reached a 1.0 release status yet, as there are still development changes and things to fix. But what is here should be tremendously useful, provided you bear in mind that there will be some changes made to the programming language and command line options between now and a 1.0 release, so any tools or documentation written will become out of date and require changes. If you are anxiously waiting a 1.0 release, please consider contributing so that it can be released sooner.
