* bpo-42398: Fix "make regen-all" race condition (GH-23362) (GH-23367)Victor Stinner2020-11-181-19/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a race condition in "make regen-all" when make -jN option is used to run jobs in parallel. The clinic.py script now only use atomic write to write files. Moveover, generated files are now left unchanged if the content does not change, to not change the file modification time. The "make regen-all" command runs "make clinic" and "make regen-importlib" targets: * "make regen-importlib" builds object files (ex: Modules/_weakref.o) from source files (ex: Modules/_weakref.c) and clinic files (ex: Modules/clinic/_weakref.c.h) * "make clinic" always rewrites all clinic files (ex: Modules/clinic/_weakref.c.h) Since there is no dependency between "clinic" and "regen-importlib" Makefile targets, these two targets can be run in parallel. Moreover, half of clinic.py file writes are not atomic and so there is a race condition when "make regen-all" runs jobs in parallel using make -jN option (which can be passed in MAKEFLAGS environment variable). Fix clinic.py to make all file writes atomic: * Add write_file() function to ensure that all file writes are atomic: write into a temporary file and then use os.replace(). * Moreover, write_file() doesn't recreate or modify the file if the content does not change to avoid modifying the file modification file. * Update test_clinic to verify these assertions with a functional test. * Remove Clinic.force attribute which was no longer used, whereas Clinic.verify remains useful.

| | | | | | | | | | | | (GH-23066) Left-recursive rules need to check for errors explicitly, since even if the rule returns NULL, the parsing might continue and lead to long-distance failures.

| | | | | | | | | | The scripts in `Tools/peg_generator/scripts` mostly assume that `ast.parse` and `compile` use the old parser, since this was the state of things, while we were developing them. They need to be updated to always use the correct parser. `_peg_parser` is being extended to support both parsing and compiling with both parsers.

* bpo-40503: PEP 615: Tests and implementation for zoneinfo (GH-19909)Paul Ganssle2020-05-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the initial implementation of PEP 615, the zoneinfo module, ported from the standalone reference implementation (see https://www.python.org/dev/peps/pep-0615/#reference-implementation for a link, which has a more detailed commit history). This includes (hopefully) all functional elements described in the PEP, but documentation is found in a separate PR. This includes: 1. A pure python implementation of the ZoneInfo class 2. A C accelerated implementation of the ZoneInfo class 3. Tests with 100% branch coverage for the Python code (though C code coverage is less than 100%). 4. A compile-time configuration option on Linux (though not on Windows) Differences from the reference implementation: - The module is arranged slightly differently: the accelerated module is `_zoneinfo` rather than `zoneinfo._czoneinfo`, which also necessitates some changes in the test support function. (Suggested by Victor Stinner and Steve Dower.) - The tests are arranged slightly differently and do not include the property tests. The tests live at test/test_zoneinfo/test_zoneinfo.py rather than test/test_zoneinfo.py or test/test_zoneinfo/__init__.py because we may do some refactoring in the future that would likely require this separation anyway; we may: - include the property tests - automatically run all the tests against both pure Python and C, rather than manually constructing C and Python test classes (similar to the way this works with test_datetime.py, which generates C and Python test cases from datetimetester.py). - This includes a compile-time configuration option on Linux (though not on Windows); added with much help from Thomas Wouters. - Integration into the CPython build system is obviously different from building a standalone zoneinfo module wheel. - This includes configuration to install the tzdata package as part of CI, though only on the coverage jobs. Introducing a PyPI dependency as part of the CI build was controversial, and this is seen as less of a major change, since the coverage jobs already depend on pip and PyPI. Additional changes that were introduced as part of this PR, most / all of which were backported to the reference implementation: - Fixed reference and memory leaks With much debugging help from Pablo Galindo - Added smoke tests ensuring that the C and Python modules are built The import machinery can be somewhat fragile, and the "seamlessly falls back to pure Python" nature of this module makes it so that a problem building the C extension or a failure to import the pure Python version might easily go unnoticed. - Adjustments to zoneinfo.__dir__ Suggested by Petr Viktorin. - Slight refactorings as suggested by Steve Dower. - Removed unnecessary if check on std_abbr Discovered this because of a missing line in branch coverage.
