Since both of these have a VFS bound, it's not clear to me that it is worth splitting them (to avoid having abstract methods on GlobMatchingImpl?). IMO: merge them.

I would love to -- I was under the impression that keeping e.g. expand_single() (and its return type) private would be a goal of part of this. That can still be achieved if e.g. expand_single() is e.g. a top-level fn -- but if that's not super important, we can just merge them into one. See @illicitonion's comment here.

canonicalize feels like a VFS thing not a GlobMatchingImplementation thing? I didn't realise we implemented it by expanding globs, that seems a little weird...

It needs to use a symlink-aware codepath in order to properly track symlink chains.

My assumption was that we'd repeatedly call read_link, rather than repeatedly making PathGlobs and calling expand :)

More than that: you need to do it for every path component up from the root. So that blah/this_is_a_link/foo/this_is_also_a_link/bar is tracked correctly.

This feels like something read_link could do itself?

Maybe. I expect that it would lead to redundant expansion of pathglobs. But let's save refactoring for a separate PR.
EDIT: Hm. It probably already leads to redundant expansion of pathglobs. But yea, separate pr.

Oh! I didn't realize we canonicalize()d in directory_listing(). With that I think it's fine (especially given the reason you mentioned -- redundant expansion).

Let's move this trait to the top of the file, and add a comment on the other one explaining that it exists because expand_single should be private, but traits don't let us do that.

Closes pantsbuild#5831 Prep for release 1.8.0dev3 (pantsbuild#5937) Ban bad `readonly` shell pattern (pantsbuild#5924) This subverts `set -e` and means that failed commands don't fail the script, which is responsible for late failures on CI such as https://travis-ci.org/pantsbuild/pants/jobs/389174049 which failed to download protoc, but only failed when something tried to use it. Fixup macosx platform version. (pantsbuild#5938) This needs to match the Travis CI osx platform we pre-build wheels on. Work towards pantsbuild#4896. Allow pants to select targets by file(s) (pantsbuild#5930) Fixes pantsbuild#5912 Problem There should be an option to accept literal files, and then select the targets that own those files. Similar to how the --changed-parent triggers a diff and the targets are selected based on the result. The proposed syntax is something like: $ ./pants \ --owner-of=this/is/a/file/name.java \ # flag triggers owner lookup --owner-of=this/is/a/file/name/too.py \ # flag triggers owner lookup compile # goal Solution I've created a global option --owner-of= that takes a list of files as a parameter, and created a OwnerCalculator class to handle the logic similar to how ChangeCalculator works with the --changed-* subsystem. Result Now users will be able to run goals on files without needing to know which target owns those files. Also, the list-owners goal can be deprecated in favor of --owner-of=some/file.py list It is important to note that multiple target selection methods are not allowed, so it fails when more than one of --changed-*, --owner-of, or target specs are supplied. e.g. this fails: $ ./pants \ --owner-of=this/is/a/file/name.java \ # flag triggers owner lookup --owner-of=this/is/a/file/name/too.py \ # flag triggers owner lookup compile <another target> Integration test for daemon environment scrubbing (pantsbuild#5893) This shows that pantsbuild#5898 works, which itself fixed pantsbuild#5854 Add the --owner-of= usage on Target Address documentation (pantsbuild#5931) Problem The documentation of the feature proposed in PR pantsbuild#5930 Solution I decided to put it inside Target Addresses because that is where a user would look if they needed a feature like this, I think. Result More docs, and that's always good. Add script to get a list of failing pants from travis (pantsbuild#5946) [jvm-compile] template-methodify JvmCompile further; add compiler choices (pantsbuild#5923) Introduce `JvmPlatform.add_compiler_choice(name)`, which allows plugins to register compilers that can be configured. This patch pulls out some template methods in JvmCompile to make it easier to extend. It also pushes some of the implementations of those methods down into ZincCompile, where appropriate. These changes should be covered by existing tests, but it could make sense to add tests around the interfaces of the new template methods. I don't anticipate there being a large number of implementations at this time though, so I didn't think it'd be worth it. Add the following template methods * `create_empty_extra_products` Allows subclasses to create extra products that other subclasses might not need, that ought to be constructed even if no compile targets are necessary. * `register_extra_products_from_contexts` rename of `_register_vts`. This allows subclasses to register their extra products for particular targets. * `select_runtime_context` Not 100% happy with this, but I'm working on something that needs to have different types of compile contexts. It allows subclasses to specify a context that provides paths for the runtime classpath if the default context isn't quite right for the usages in the base class. * `create_compile_jobs` Pulled this out into a separate method so that subclasses can create multiple graph jobs per target. * Pushed down behavior from JvmCompile that should live in zinc via the template methods extracted above. There's probably more that could be done here, but this was the first cut of it. * Moved the execute definition from BaseZincCompile to ZincCompile so that it's possible to subclass BaseZincCompile with a different compiler name. release notes for 1.7.0.rc1 (pantsbuild#5942) Use target not make_target in some tests (pantsbuild#5939) This pushes parsing of the targets through the engine, rather than bypassing it. This is important because I'm about to make these targets require an EagerFilesetWithSpec as their source/sources arg, rather than being happy with a list of strings. Add new remote execution options (pantsbuild#5932) As described in pantsbuild#5904, a few configuration values that are important to testing of remote execution are currently hardcoded. Extract existing options to a `ExecutionOptions` collection (which should become a `Subsystem` whenever we add support for consuming `Subsystems` during bootstrap), and add the new options. Fixes pantsbuild#5904. Separate the resolution cache and repository cache in Ivy (pantsbuild#5844) move glob matching into its own file (pantsbuild#5945) See pantsbuild#5871, where we describe an encapsulation leak created by implementing all of the glob expansion logic in the body of `VFS`. - Create `glob_matching.rs`, exporting the `GlobMatching` trait, which exports the two methods `canonicalize` and `expand`, which call into methods in a private trait `GlobMatchingImplementation`. **Note:** `canonicalize` calls `expand`, and vice versa, which is why both methods were moved to `glob_matching.rs`. Orthogonal glob matching logic is made into a trait that is implemented for all types implementing `VFS`, removing the encapsulation leak. The `VFS` trait is now just four method signature declarations, making the trait much easier to read and understand. Enable fromfile support for --owner-of and increase test coverage (pantsbuild#5948) The new `--owner-of` option was broken in the context of `pantsd`, but didn't have test coverage due to the `--changed` and `--owner-of` tests not running under `pantsd`. Additionally, `fromfile` support is useful for this option, but was not enabled. Mark some integration tests as needing to run under the daemon, and enable `fromfile` support for `--owner-of`. [pantsd] Robustify client connection logic.

(pantsbuild#5953) Zinc used to be shaded before the `1.x.y` upgrade (pantsbuild#4729), but shading was removed due to an overabundance of optimism. When testing the zinc upgrade internally, we experienced a classpath collision between an annotation processor and zinc (in guava, although zinc has many other dependencies that could cause issues). Shade zinc, and ensure that our annotation processor uses a very old guava in order to attempt to force collisions in future. Improve PythonInterpreterCache logging (pantsbuild#5954) When users have issues building their Python interpreter cache, they are often very confused because does not currently log much about the process to help users debug. Here we add log lines describing what/where Pants looks to build the interpreter cache, and the results of what it found. This should help users better understand/debug the process. use liblzma.dylib for xz on osx and add platform-specific testing to the rust osx shard (pantsbuild#5936) See pantsbuild#5928. The `xz` archiver wasn't tested on osx at all, and failed to find `liblzma.so` on osx (it should have been `liblzma.dylib`). There were additional errors with library search paths reported in that PR which I was not immediately able to repro. This PR hopefully fixes all of those errors, and ensures they won't happen again with the addition of platform-specific testing (see previous issue at pantsbuild#5920). - Switch to a statically linked `xz`. - Fix the incorrect key `'darwin'` in the platform dictionary in the `LLVM` subsystem (to `'mac'`). - Add the tag `platform_specific_behavior` to the new python target `tests/python/pants_test/backend/python/tasks:python_native_code_testing`, which covers the production of `python_dist()`s with native code. - Add the `-z` argument to `build-support/bin/ci.sh` to run all tests with the `platform_specific_behavior` tag. Also clean up old unused options in the getopts call, and convert echo statements to a simpler heredoc. - Change the name of the "Rust Tests OSX" shard to "Rust + Platform-specific Tests OSX", and add the `-z` switch to the `ci.sh` invocation. **Note:** the tests in `tests/python/pants_test/backend/native/subsystems` are going to be removed in pantsbuild#5815, otherwise they would be tagged similarly. `./pants test tests/python/pants_test/backend/python/tasks:python_native_code_testing` now passes on osx, and this fact is now being tested in an osx shard in travis. Support output directory saving for local process execution.

Switch to constructing the `RuleGraph` recursively, and unify a few disparate diagnostic messages. Helps to prepare for further refactoring in pantsbuild#5788. Allow manylinux wheels when resolving plugins. (pantsbuild#5959) Also plumb manylinux resolution support for the python backend, on by default, but configurable via `python_setup.resolver_use_manylinux`. Fixes pantsbuild#5958 `exclude-patterns` and `tag` should apply only to roots (pantsbuild#5786) The `--exclude-patterns` flag currently applies to inner nodes, which causes odd errors. Moreover, tags should also apply only to roots. See pantsbuild#5189. - added `tag` & `exclude_patterns` as params to `Specs` - add tests for both - modify changed tests to pass for inner node filtering Fixes pantsbuild#5189. Remove value wrapper on the python side of ffi. (pantsbuild#5961) As explained in the comment in this change, the overhead of wrapping our CFFI "handle"/`void*` instances in a type that is shaped like the `Value` struct was significant enough to care about. Since the struct has zero overhead on the rust side, whether we represent it as typedef or a struct on the python side doesn't make a difference (except in terms of syntax). 6% faster `./pants list ::` in Twitter's repo. return an actual field use temporary native-compile goal Cobertura coverage: Include the full target closure's classpath entries for instrumentation (pantsbuild#5879) Sometimes Cobertura needs access to the dependencies of class files being instrumented in order to rewrite them (pantsbuild#5878). This patch adds an option that creates a manifest jar and adds an argument to the Cobertura call so that it can take advantage of it. class files that need to determine a least upper bound in order to be rewritten can now be instrumented. Fixes pantsbuild#5878 add ticket link fix xcode install locations and reduce it to a single dir_option return the correct amount of path entries Record start times per graph node and expose a method to summarize them. (pantsbuild#5964) In order to display "significant" work while it is running on the engine, we need to compute interesting, long-running leaves. Record start times per entry in the `Graph`, and add a method to compute a graph-aware top-k longest running leaves. We traverse the graph "longest running first", and emit the first `k` leaves we encounter. While this will almost certainly need further edits to maximize it's usefulness, visualization can begun to be built atop of it. Prepare the 1.8.0.dev4 release (pantsbuild#5969) Mark a few options that should not show up in `./pants help`. (pantsbuild#5968) `./pants help` contains core options that are useful to every pants command, and the vast majority of global options are hidden in order to keep it concise. A few non-essential options ended up there recently. Hide them. adding more documentation for python_app (pantsbuild#5965) The python_app target doesn't have the documentation specific for it and has a documentation that is specific to jvm_app. Added a few lines of documentation. There is no system-wide change, only a documentation change. Remove DeprecatedPythonTaskTestBase (pantsbuild#5973) Use PythonTaskTestBase instead. Fixes pantsbuild#5870 Chris first commit on fresh rebase Merge branch 'ctypes-test-project' of github.com:cosmicexplorer/pants into clivingston/ctypes-test-project-third-party unrevert reverted fix (NEEDS FOLLOWUP ISSUE!) put in a better fix for the strict_deps error until the followup issue is made add ticket link Merge branch 'ctypes-test-project' of github.com:cosmicexplorer/pants into clivingston/ctypes-test-project-third-party Shorten safe filenames further, and combine codepaths to make them readable. (pantsbuild#5971) Lower the `safe_filename` path component length limit to 100 characters, since the previous 255 value did not account for the fact that many filesystems also have a limit on total path length. This "fixes" the issue described in pantsbuild#5587, which was caused by using this method via `build_invalidator.py`. Additionally, merge the codepath from `Target.compute_target_id` which computes a readable shortened filename into `safe_filename`, and expand tests. This removes some duplication, and ensure that we don't run into a similar issue with target ids. The specific error from pantsbuild#5587 should be prevented, and consumers of `safe_filename` should have safe and readable filenames. Fixes pantsbuild#5587. Whitelist the --owner-of option to not restart the daemon. (pantsbuild#5979) Because the `--owner-of` option was not whitelisted as `daemon=False`, changing its value triggered unnecessary `pantsd` restarts. Whitelist it. Prepare the 1.8.0rc0 release. (pantsbuild#5980) Robustify test_namespace_effective PYTHONPATH. (pantsbuild#5976) The real problem is noted, but this quick fix should bolster against interpreter cache interpreters pointing off to python binaries that have no setuptools in their associated site-packages. Fixes pantsbuild#5972 make_target upgrades sources to EagerFilesetWithSpec (pantsbuild#5974) This better simulates how the engine parses BUILD files, giving a more faithful experience in tests. I'm about to make it a warning/error to pass a list of strings as the sources arg, so this will make tests which use make_target continue to work after that. Also, make cloc use base class scheduler instead of configuring its own. Lib and include as a dep-specifc location source attribute is automatically promoted to sources (pantsbuild#5908) This means that either the `source` or `sources` attribute can be used for any rule which expects sources. Places that `source` was expected still verify that the correct number of sources are actually present. Places that `sources` was expected will automatically promote `source` to `sources`. This is a step towards all `sources` attributes being `EagerFilesetWithSpec`s, which will make them cached in the daemon, and make them easier to work with with both v2 remote execution and in the v2 engine in general. It also provides common hooks for input file validation, rather than relying on them being done ad-hoc in each `Target` constructor. For backwards compatibility, both attributes will be populated on `Target`s, but in the future only the sources value will be provided. `sources` is guaranteed to be an `EagerFilesetWithSpec` whichever of these mechanisms is used. A hook is provided for rules to perform validation on `sources` at build file parsing time. Hooks are put in place for non-contrib rule types which currently take a `source` attribute to verify that the correct number of sources are provided. I imagine at some point we may want to add a "file type" hook too, so that rules can error if files of the wrong type were added as sources. This is a breaking change for rules which use both the `source` and `sources` attributes (and where the latter is not equivalent to the former), or where the `source` attribute is used to refer to something other than a file. `source` is now becoming a reserved attribute name, as `sources` and `dependencies` already are. This is also a breaking change for rules which use the `source` attribute, but never set `sources` in a Payload. These will now fail to parse. This is also a slightly breaking change for the `page` rule - before, omitting the `source` attribute would parse, but fail at runtime. Now, it will fail to parse. This is also a breaking change in that in means that the source attribute is now treated like a glob, and so if a file is specified which isn't present, it will be ignored instead of error. This feels a little sketchy, but it turns out we did the exact same thing by making all sources lists be treated like globs... Override get_sources for pants plugins (pantsbuild#5984) 1.7.0 release notes (pantsbuild#5983) No additional changes, so it's a very short release note.

ok, now it works on linux again too first round of review - NB: refactors the organization of the `results_dir` for python_dist()! - move ctypes integration testing into python backend tests revert some unnecessary changes refactor native_artifact to be a datatype fix some copyright years add ctypes integration test add assert_single_element method in collections.py decouple the native tools for setup.py from the execution environment streamline the selection of the native tools for setup.py invocation make gcc depend on binutils on linux for the 'as' assembler fix logging visibility by moving it back into the task make the check for the external llvm url more clear refactor local dist building a bit - use SetupPyRunner.DIST_DIR as the source of truth - add a separate subdir of the python_dist target's results_dir for the python_dist sources - move shraed libs into the new subdir fix imports second round of review - fixed bugs - expanded error messages and docstrings make a couple docstring changes fix dist platform selection ('current' is not a real platform) lint fixes fix broken regex which modifies the `.dylib` extension for python_dist() fix the ctypes integration test respond to some review comments clear the error message if we can't find xcode cli tools refactor the compilation and linking pipeline to use subsystems - also add `PythonNativeCode` subsystem to bridge the native and python backends refactor the compilation and linking pipeline to use subsystems add some notes fix rebase issues add link to pantsbuild#5788 -- maybe use variants for args for static libs move `native_source_extensions` to a new `PythonNativeCode` subsystem update native toolchain docs and remove bad old tests move tgt_closure_platforms into the new `PythonNativeCode` subsystem remove unnecessary logging remove compile_settings_class in favor of another abstractmethod refactor `NativeCompile` and add documentation improve debug logging in NativeCompile document NativeCompileSettings refactor and add docstrings convert provides= to ctypes_dylib= and add many more docstrings remove or improve TODOs improve or remove FIXMEs improve some docstrings, demote a FIXME, and add a TODO link FIXMEs to a ticket add notes to the ctypes testproject update mock object for strict deps -- test passes fix failing integration test on osx add hack to let travis pass fix the system_id key in llvm and add a shameful hack to pass travis swap the order of alias_types remove unused EmptyDepContext class remove -settings suffix from compile subsystem options scopes add AbstractClass to NativeLibrary bump implementation_version for python_dist() build - we have changed the layout of the results_dir in this PR add ticket link and fix bug revert indentation changes to execute() method refactor `assert_single_element()` revert addition of `narrow_relative_paths()` add link to pantsbuild#5950 move common process invocation logic into NativeCompile revert an unnecessary change turn an assert into a full exception revert unnecessary change use get_local_platform() wherever possible delete duplicate llvm subsystem fix xcode cli tools resolution change `ctypes_dylib=` to `ctypes_native_library=` add a newline move UnsupportedPlatformError to be a class field remove unused codegen_types field fix zinc-compiler options to be valid ones return an actual field use temporary native-compile goal add ticket link fix xcode install locations and reduce it to a single dir_option return the correct amount of path entries unrevert reverted fix (NEEDS FOLLOWUP ISSUE!) put in a better fix for the strict_deps error until the followup issue is made add ticket link hardcode in c/c++ language levels for now remove all the unnecessary code relating to file extensions fix osx failures and leave a ticket link Add rang header-only lib for integration testing Merge branch 'ctypes-test-project' of github.com:cosmicexplorer/pants into clivingston/ctypes-test-project-third-party Fix TestSetupPyInterpreter.test_setuptools_version (pantsbuild#5988) Previously the test failed to populate the `PythonInterpreter` data product leading to a fallback to the current non-bare interpreter which allowed `setuptools` from `site-packages` to leak in. Fixes pantsbuild#5467 Refactor conan grab into subsystem Engine looks up default sources when parsing (pantsbuild#5989) Rather than re-implementing default source look-up. This pushes sources parsing of default sources through the engine, in parallel, rather than being later synchronous python calls. This also works for plugin types, and doesn't change any existing APIs. It updates the Go patterns to match those that the engine currently performs, rather than ones which aren't actually used by any code. Add unit tests, refactor C/C++ targets which can be compiled/linked and used in python_dist() with ctypes (pantsbuild#5815) It is currently possible to expose native code to Python by compiling it in a `python_dist()` target, specifying C or C++ source files as a `distutils.core.Extension` in the `setup.py` file, as well as in the target's sources. `python_dist()` was introduced in pantsbuild#5141. We introduced a "native toolchain" to compile native sources for this use case in pantsbuild#5490. Exposing Python code this way requires using the Python native API and `#include <Python.h>` in your source files. However, python can also interact with native code that does not use the Python native API, using the provided `ctypes` library. For this to work, the `python_dist()` module using `ctypes` needs to have a platform-specific shared library provided within the package. This PR introduces the targets, tasks, and subsystems to compile and link a shared library from native code, then inserts it into the `python_dist()` where it is easily accessible. - Introduce the `ctypes_compatible_c_library()` target which covers C sources (`ctypes_compatible_cpp_library()` for C++), and can specify what to name the shared library created from linking the object files compiled from its sources and dependencies. - Introduce `CCompile`, `CppCompile`, and `LinkSharedLibraries` to produce the shared libraries from the native sources. The compile tasks use options `CCompileSettings` or `CppCompileSettings` to define file extensions for "header" and "source" files. - Introduce the `CCompileSettings` and `CppCompileSettings` subsystems to control compile settings for those languages. - Convert `BuildLocalPythonDistributions` to proxy to the native backend through the new `PythonNativeCode` subsystem. - Move all the `BinaryTool` subsystems to a `subsystems/binaries` subdirectory, and expose them to the v2 engine through `@rule`s defined in the subsystem's file. - Move some of the logic in `pex_build_util.py` to `setup_py.py`, and expose datatypes composing the setup.py environment through `@rule`s in `setup_py.py`. `SetupPyRunner.for_bdist_wheel()` was created to set the wheel's platform, if the `python_dist()` target contains any native sources of its own, or depends on any `ctypes_compatible_*_library`s. **Note:** the new targets are specifically prefixed with `ctypes_compatible_` because we don't yet eclipse the functionality of `contrib/cpp`. When the targets become usable for more than this one use case, the name should be changed. To see how to link up native and Python code with `ctypes`, here's (most of) the contents of `testprojects/src/python/python_distribution/ctypes`: *BUILD*: ```python ctypes_compatible_c_library( name='c_library', sources=['some_math.h', 'some_math.c', 'src-subdir/add_three.h', 'src-subdir/add_three.c'], ctypes_dylib=native_artifact(lib_name='asdf-c'), ) ctypes_compatible_cpp_library( name='cpp_library', sources=['some_more_math.hpp', 'some_more_math.cpp'], ctypes_dylib=native_artifact(lib_name='asdf-cpp'), ) python_dist( sources=[ 'setup.py', 'ctypes_python_pkg/__init__.py', 'ctypes_python_pkg/ctypes_wrapper.py', ], dependencies=[ ':c_library', ':cpp_library', ], ) ``` *setup.py*: ```python setup( name='ctypes_test', version='0.0.1', packages=find_packages(), # Declare two files at the top-level directory (denoted by ''). data_files=[('', ['libasdf-c.so', 'libasdf-cpp.so'])], ) ``` *ctypes_python_pkg/ctypes_wrapper.py*: ```python import ctypes import os def get_generated_shared_lib(lib_name): # These are the same filenames as in setup.py. filename = 'lib{}.so'.format(lib_name) # The data files are in the root directory, but we are in ctypes_python_pkg/. rel_path = os.path.join(os.path.dirname(__file__), '..', filename) return os.path.normpath(rel_path) asdf_c_lib_path = get_generated_shared_lib('asdf-c') asdf_cpp_lib_path = get_generated_shared_lib('asdf-cpp') asdf_c_lib = ctypes.CDLL(asdf_c_lib_path) asdf_cpp_lib = ctypes.CDLL(asdf_cpp_lib_path) def f(x): added = asdf_c_lib.add_three(x) multiplied = asdf_cpp_lib.multiply_by_three(added) return multiplied ``` Now, the target `testprojects/src/python/python_distribution/ctypes` can be depended on in a BUILD file, and other python code can freely use `from ctypes_python_pkg.ctypes_wrapper import f` to start jumping into native code. 1. pantsbuild#5933 2. pantsbuild#5934 3. pantsbuild#5949 4. pantsbuild#5950 5. pantsbuild#5951 6. pantsbuild#5962 7. pantsbuild#5967 8. pantsbuild#5977 Add simple integration test Pull in master Minor cleanup Fix CI errors Debug log stdout Fix integration test Fix integration test Fix lint error on third party

Problem
See #5871, where we describe an encapsulation leak created by implementing all of the glob expansion logic in the body of
VFS.Solution
glob_matching.rs, exporting theGlobMatchingtrait, which exports the two methodscanonicalizeandexpand, which call into methods in a private traitGlobMatchingImplementation.Note:
canonicalizecallsexpand, and vice versa, which is why both methods were moved toglob_matching.rs.Result
Orthogonal glob matching logic is made into a trait that is implemented for all types implementing
VFS, removing the encapsulation leak. TheVFStrait is now just four method signature declarations, making the trait much easier to read and understand.
