* gh-135801: Add the module parameter to compile() etc (GH-139652)Serhiy Storchaka2025-11-131-4/+5
| | | | | | | Many functions related to compiling or parsing Python code, such as compile(), ast.parse(), symtable.symtable(), and importlib.abc.InspectLoader.source_to_code() now allow to pass the module name used when filtering syntax warnings.

* gh-115911: Ignore PermissionError during import from cwd (#116131)Alex Willmer2025-01-261-1/+1
| | | | | | | | | | | | | | | | Ignore PermissionError when checking cwd during import On macOS `getcwd(3)` can return EACCES if a path component isn't readable, resulting in PermissionError. `PathFinder.find_spec()` now catches these and ignores them - the same treatment as a missing/deleted cwd. Introduces `test.support.os_helper.save_mode(path, ...)`, a context manager that restores the mode of a path on exit. This is allows finer control of exception handling and robust environment restoration across platforms in `FinderTests.test_permission_error_cwd()`. Co-authored-by: Jason R.

* gh-122907: Fix Builds Without HAVE_DYNAMIC_LOADING Set (gh-122952)Eric Snow2024-08-131-8/+8
| | | As of 529a160 (gh-118204), building with HAVE_DYNAMIC_LOADING stopped working. This is a minimal fix just to get builds working again. There are actually a number of long-standing deficiencies with HAVE_DYNAMIC_LOADING builds that need to be resolved separately.

* gh-119180: Update the magic number (#119397)Jelle Zijlstra2024-05-251-1/+1
| | | | PR #119321 added a comment about the magic number bump but did not actually apply the new magic number.
* gh-119180: Add LOAD_COMMON_CONSTANT opcode (#119321)Jelle Zijlstra2024-05-221-2/+3
| | | | | | | | | | The PEP 649 implementation will require a way to load NotImplementedError from the bytecode. @markshannon suggested implementing this by converting LOAD_ASSERTION_ERROR into a more general mechanism for loading constants. This PR adds this new opcode. I will work on the rest of the implementation of the PEP separately. Co-authored-by: Irit Katriel <1055913+iritkatriel@users.noreply.github.com>

| | | | | | | | | | | | | | | * Reads zip64 files as produced by the zipfile module * Include tests (somewhat slow, however, because of the need to create "large" zips) * About the same amount of strictness reading invalid zip files as zipfile has * Still works on files with prepended data (like pex) There are a lot more test cases at https://github.com/thatch/zipimport64/ that give me confidence that this works for real-world files.

* gh-109039: Branch prediction for Tier 2 interpreter (#109038)Guido van Rossum2023-09-111-1/+2
| | | | | | | | | | | This adds a 16-bit inline cache entry to the conditional branch instructions POP_JUMP_IF_{FALSE,TRUE,NONE,NOT_NONE} and their instrumented variants, which is used to keep track of the branch direction. Each time we encounter these instructions we shift the cache entry left by one and set the bottom bit to whether we jumped. Then when it's time to translate such a branch to Tier 2 uops, we use the bit count from the cache entry to decided whether to continue translating the "didn't jump" branch or the "jumped" branch. The counter is initialized to a pattern of alternating ones and zeros to avoid bias. The .pyc file magic number is updated. There's a new test, some fixes for existing tests, and a few miscellaneous cleanups.
