* [3.10] bpo-34990: Treat the pyc header's mtime in compileall as an unsigned ↵Miss Islington (bot)2021-08-241-7/+10
| | | | | | | | int (GH-19708) (cherry picked from commit bb21e28fd08f894ceff2405544a2f257d42b1354) Co-authored-by: Ammar Askar <ammar@ammaraskar.com> Co-authored-by: Stéphane Wirtel <stephane@wirtel.be>
* bpo-14678: Update zipimport to support importlib.invalidate_caches() (GH-24159)Desmond Cheong2021-03-081-0/+41
| | | Added an invalidate_caches() method to the zipimport.zipimporter class based on the implementation of importlib.FileFinder.invalidate_caches(). This was done by adding a get_files() method and an _archive_mtime attribute to zipimport.zipimporter to check for updates or cache invalidation whenever the cache of files and toc entry information in the zipimporter is accessed.
* bpo-24792: Fix zipimporter masking the cause of import errors (GH-22204)Irit Katriel2020-12-191-4/+4
| | | | | zipimport's _unmarshal_code swallows import errors and then _get_module_code doesn't know the cause of the error, and returns the generic, and sometimes incorrect, 'could not find...'. Automerge-Triggered-By: GH:brettcannon

* bpo-40275: More lazy imports in test.support (GH-20131)Hai Shi2020-05-181-1/+1
| | | | | | | | | | | | | | | | | | | Make the the following imports lazy in test.support: * bz2 * gzip * lzma * resource * zlib The following test.support decorators now need to be called with parenthesis: * @support.requires_bz2 * @support.requires_gzip * @support.requires_lzma * @support.requires_zlib For example, "@requires_zlib" becomes "@requires_zlib()".

* closes bpo-31650: PEP 552 (Deterministic pycs) implementation (#4575)Benjamin Peterson2017-12-091-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | Python now supports checking bytecode cache up-to-dateness with a hash of the source contents rather than volatile source metadata. See the PEP for details. While a fairly straightforward idea, quite a lot of code had to be modified due to the pervasiveness of pyc implementation details in the codebase. Changes in this commit include: - The core changes to importlib to understand how to read, validate, and regenerate hash-based pycs. - Support for generating hash-based pycs in py_compile and compileall. - Modifications to our siphash implementation to support passing a custom key. We then expose it to importlib through _imp. - Updates to all places in the interpreter, standard library, and tests that manually generate or parse pyc files to grok the new format. - Support in the interpreter command line code for long options like --check-hash-based-pycs. - Tests and documentation for all of the above.

| | | | | | | bad zlib.decompress() (GH-3784) While a rare potential failure (it requires swapping out zlib.decompress() itself and forcing it to return a non-bytes object), this change prevents a potential C-level assertion failure and instead substitutes it with an exception. Thanks to Oren Milman for the patch.

| | | | | | | | | | | | | | | | | | Previously zipimport mistakenly limited namespace support to only the top-level of the zipfile when it should have supported an arbitrary depth. Thanks to Phil Connel for the bug report and initial patch and Mike Romberg for the final patch.

* Issue #23696: Remove test on ZipImportError.__context__ because the context isVictor Stinner2015-03-201-1/+0
| | | | | | | | | None on Windows. When the file is not readable, the error occurs at open on UNIX. On Windows, the error only occurs at the first operation on the open file. It would require to many changes to set __context__ to an OSError for all file operations, for a little benefit (__context__ is almost never used).
