| 62972d9 | Paul Ganssle | 16 May 2020, 08:20:06 UTC | bpo-40503: PEP 615: Tests and implementation for zoneinfo (GH-19909) 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. | 16 May 2020, 08:20:06 UTC |

This puts much simpler text up front along with an example. As it was, the zip built-in docstring was technically correct. But too technical for the reader who shouldn't _need_ to know about `__next__` and `StopIteration` as most people do not need to understand the internal implementation details of the iterator protocol in their daily life. This is a documentation only change, intended to be backported to 3.8; it is only tangentially related to PEP-618 which might offer new behavior options in the future. Wording based a bit more on enumerate per Brandt's suggestion. This gets rid of the legacy wording paragraph which seems too tied to implementation details of the iterator protocol which isn't relevant here.

(GH-19768) (Note: PEP 554 is not accepted and the implementation in the code base is a private one for use in the test suite.) If code running in a subinterpreter raises an uncaught exception then the "run" call in the calling interpreter fails. A RunFailedError is raised there that summarizes the original exception as a string. The actual exception type, __cause__, __context__, state, etc. are all discarded. This turned out to be functionally insufficient in practice. There is a more helpful solution (and PEP 554 has been updated appropriately). This change adds the exception propagation behavior described in PEP 554 to the _xxsubinterpreters module. With this change a copy of the original exception is set to __cause__ on the RunFailedError. For now we are using "pickle", which preserves the exception's state. We also preserve the original __cause__, __context__, and __traceback__ (since "pickle" does not preserve those). https://bugs.python.org/issue32604 | 07 May 2020, 14:56:01 UTC |
