* gh-116664: In _warnings.c, make filters_version access thread-safe (#117374)Erlend E. Aasland2024-03-291-6/+9
| | | | - assert that the lock is held in already_warned() - protect 'filters_version' increment in warnings_filters_mutated_impl()
* gh-117348: Refactored RawConfigParser._read for similicity and ↵Jason R. Coombs2024-03-292-147/+185
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | comprehensibility (#117372) * Extract method for _read_inner, reducing complexity and indentation by 1. * Extract method for _raise_all and yield ParseErrors from _read_inner. Reduces complexity by 1 and reduces touch points for handling errors in _read_inner. * Prefer iterators to splat expansion and literal indexing. * Extract method for _strip_comments. Reduces complexity by 7. * Model the file lines in a class to encapsulate the comment status and cleaned value. * Encapsulate the read state as a dataclass * Extract _handle_continuation_line and _handle_rest methods. Reduces complexity by 8. * Reindent * At least for now, collect errors in the ReadState * Check for missing section header separately. * Extract methods for _handle_header and _handle_option. Reduces complexity by 6. * Remove unreachable code. Reduces complexity by 4. * Remove unreachable branch * Handle error condition early. Reduces complexity by 1. * Add blurb * Move _raise_all to ParsingError, as its behavior is most closely related to the exception class and not the reader. * Split _strip* into separate methods. * Refactor _strip_full to compute the strip just once and use 'not any' to determine the factor. * Replace use of 'sys.maxsize' with direct computation of the stripped value. * Extract has_comments as a dynamic property. * Implement clean as a cached property. * Model comment prefixes in the RawConfigParser within a prefixes namespace. * Use a regular expression to search for the first match. Avoids mutating variables and tricky logic and over-computing all of the starts when only the first is relevant.
* gh-117300: Use stop the world to make `sys._current_frames` and ↵Sam Gross2024-03-292-1/+6
| | | | | | | | | | `sys._current_exceptions` thread-safe. (#117301) This adds a stop the world pause to make the two functions thread-safe when the GIL is disabled in the free-threaded build. Additionally, the main test thread may call `sys._current_exceptions()` as soon as `g_raised.set()` is called. The background thread may not yet reach the `leave_g.wait()` line.
* Fix broken format in error for bad input in summarize_stats.py (#117375)Guido van Rossum2024-03-291-1/+1
| | | When you pass the script a non-existent input file, you get a TypeError instead of the intended ValueError.
* gh-111926: Avoid locking in PyType_IsSubtype (#117275)mpage2024-03-291-8/+1
| | | | | | | | | | | | | Read the MRO in a thread-unsafe way in `PyType_IsSubtype` to avoid locking. Fixing this is tracked in #117306. The motivation for this change is in support of making weakrefs thread-safe in free-threaded builds: `WeakValueDictionary` uses a special dictionary function, `_PyDict_DelItemIf` to remove dead weakrefs from the dictionary. `_PyDict_DelItemIf` removes a key if a user supplied predicate evaluates to true for the value associated with the key. Crucially for the `WeakValueDictionary` use case, the predicate evaluation + deletion sequence is atomic, provided that the predicate doesn’t suspend. The predicate used by `WeakValueDictionary` includes a subtype check, which we must ensure doesn't suspend in free-threaded builds.
* gh-117323: Make `cell` thread-safe in free-threaded builds (#117330)Sam Gross2024-03-2911-43/+83
| | | Use critical sections to lock around accesses to cell contents. The critical sections are no-ops in the default (with GIL) build.
* gh-117344: Skip flaky tests in free-threaded build (#117355)Sam Gross2024-03-292-0/+2
| | | | | The tests are not reliable with the GIL disabled. In theory, they can fail with the GIL enabled too, but the failures are much more likely with the GIL disabled.
* gh-112529: Don't untrack tuples or dicts with zero refcount (#117370)Sam Gross2024-03-291-15/+18
| | | | | | | | The free-threaded GC sometimes sees objects with zero refcount. This can happen due to the delay in merging biased reference counting fields, and, in the future, due to deferred reference counting. We should not untrack these objects or they will never be collected. This fixes the refleaks in the free-threaded build.

* gh-89739: gh-77140: Support zip64 in zipimport (GH-94146)Tim Hatch2024-03-286-39/+154
| | | | | | | | | | | | | | | * 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.
