* gh-119180: Update the magic number (#119397)Jelle Zijlstra2024-05-252-1/+2
| | | | PR #119321 added a comment about the magic number bump but did not actually apply the new magic number.

* GH-119496: accept UTF-8 BOM in .pth files (GH-119503)Alyssa Coghlan2024-05-241-1/+3
| | | | | | | | | | `Out-File -Encoding utf8` and similar commands in Windows Powershell 5.1 emit UTF-8 with a BOM marker, which the regular `utf-8` codec decodes incorrectly. `utf-8-sig` accepts a BOM, but also works correctly without one. This change also makes .pth files match the way Python source files are handled. Co-authored-by: Inada Naoki <songofacandy@gmail.com>
* gh-69214: Fix fcntl.ioctl() request type (#119498)Victor Stinner2024-05-243-8/+12

* gh-119461: Fix ThreadedVSOCKSocketStreamTest (#119465)Victor Stinner2024-05-233-4/+8
| | | | | | | | | | Add socket.VMADDR_CID_LOCAL constant. Fix ThreadedVSOCKSocketStreamTest: if get_cid() returns the host address or the "any" address, use the local communication address (loopback): VMADDR_CID_LOCAL. On Linux 6.9, apparently, the /dev/vsock device is now available but get_cid() returns VMADDR_CID_ANY (-1).
* gh-118727: Don't drop the GIL in `drop_gil()` unless the current thread ↵Brett Simmers2024-05-235-55/+68
| | | | | | | | | | | | | | | | | holds it (#118745) `drop_gil()` assumes that its caller is attached, which means that the current thread holds the GIL if and only if the GIL is enabled, and the enabled-state of the GIL won't change. This isn't true, though, because `detach_thread()` calls `_PyEval_ReleaseLock()` after detaching and `_PyThreadState_DeleteCurrent()` calls it after removing the current thread from consideration for stop-the-world requests (effectively detaching it). Fix this by remembering whether or not a thread acquired the GIL when it last attached, in `PyThreadState._status.holds_gil`, and check this in `drop_gil()` instead of `gil->enabled`. This fixes a crash in `test_multiprocessing_pool_circular_import()`, so I've reenabled it.

* gh-119396: Optimize PyUnicode_FromFormat() UTF-8 decoder (#119398)Victor Stinner2024-05-221-62/+141
| | | | | | | | | | | | | | | | | Add unicode_decode_utf8_writer() to write directly characters into a _PyUnicodeWriter writer: avoid the creation of a temporary string. Optimize PyUnicode_FromFormat() by using the new unicode_decode_utf8_writer(). Rename unicode_fromformat_write_cstr() to unicode_fromformat_write_utf8(). Microbenchmark on the code: return PyUnicode_FromFormat( "%s %s %s %s %s.", "format", "multiple", "utf8", "short", "strings"); Result: 620 ns +- 8 ns -> 382 ns +- 2 ns: 1.62x faster.

* gh-117505: Run ensurepip in isolated env in Windows installer (GH-118257)Michael Vincent2024-05-222-2/+3
| | | ensurepip forks a subprocess to run pip itself, but that subprocess only inherits a -I isolated mode flag (see _run_pip() in Lib/ensurepip/__init__.py), not the "-E -s" flags that the installer has been using. This means that parts of ensurepip don't actually run in an isolated environment and can make incorrect decisions based on packages installed in the user site-packages.
* gh-119247: Add macros to use PySequence_Fast safely in free-threaded build ↵Josh {*()} Rosenberg2024-05-224-3/+106
| | | | | | | | (#119315) Add `Py_BEGIN_CRITICAL_SECTION_SEQUENCE_FAST` and `Py_END_CRITICAL_SECTION_SEQUENCE_FAST` macros and update `str.join` to use them. Also add a regression test that would crash reliably without this patch.

* Remove almost all unpaired backticks in docstrings (#119231)Geoffrey Thomas2024-05-2239-172/+172
| | | | | | | | | | | | | | | | | | As reported in #117847 and #115366, an unpaired backtick in a docstring tends to confuse e.g. Sphinx running on subclasses of standard library objects, and the typographic style of using a backtick as an opening quote is no longer in favor. Convert almost all uses of the form The variable `foo' should do xyz to The variable 'foo' should do xyz and also fix up miscellaneous other unpaired backticks (extraneous / missing characters). No functional change is intended here other than in human-readable docstrings.
* gh-119213: Be More Careful About _PyArg_Parser.kwtuple Across Interpreters ↵Eric Snow2024-05-2210-3/+144
| | | | | | | | | (gh-119331) _PyArg_Parser holds static global data generated for modules by Argument Clinic. The _PyArg_Parser.kwtuple field is a tuple object, even though it's stored within a static global. In some cases the tuple is statically allocated and thus it's okay that it gets shared by multiple interpreters. However, in other cases the tuple is set lazily, allocated from the heap using the active interprepreter at the point the tuple is needed. This is a problem once that interpreter is destroyed since _PyArg_Parser.kwtuple becomes at dangling pointer, leading to crashes. It isn't a problem if the tuple is allocated under the main interpreter, since its lifetime is bound to the lifetime of the runtime. The solution here is to temporarily switch to the main interpreter. The alternative would be to always statically allocate the tuple. This change also fixes a bug where only the most recent parser was added to the global linked list.

* gh-60191: Implement ast.compare (#19211)Batuhan Taskaya2024-05-225-5/+210
| | | | | | | | | | * bpo-15987: Implement ast.compare Add a compare() function that compares two ASTs for structural equality. There are two set of attributes on AST node objects, fields and attributes. The fields are always compared, since they represent the actual structure of the code. The attributes can be optionally be included in the comparison. Attributes capture things like line numbers of column offsets, so comparing them involves test whether the layout of the program text is the same. Since whitespace seems inessential for comparing ASTs, the default is to compare fields but not attributes. ASTs are just Python objects that can be modified in arbitrary ways. The API for ASTs is under-specified in the presence of user modifications to objects. The comparison respects modifications to fields and attributes, and to _fields and _attributes attributes. A user could create obviously malformed objects, and the code will probably fail with an AttributeError when that happens. (For example, adding "spam" to _fields but not adding a "spam" attribute to the object.) Co-authored-by: Jeremy Hylton <jeremy@alum.mit.edu>
