* bpo-33375: Fix GCC warning in Python/_warnings.c (GH-7556)Zackery Spytz2018-06-091-1/+0
| | | _Py_IDENTIFIER(argv) is now unused.
* bpo-33375: Get filename for warnings from frame.f_code.co_filename (GH-6622)Thomas Kluyver2018-06-081-66/+4
| | | More consistent with how other parts of Python find the filename (e.g. tracebacks and pdb).
* bpo-33803: Fix a crash in hamt.c (#7504)Yury Selivanov2018-06-081-0/+2
|
* bpo-33720: Reduces maximum marshal recursion depth on release builds. (GH-7401)Steve Dower2018-06-041-1/+7
|
* bpo-31849: Fix warning in pyhash.c (GH-6799)A. Jesse Jiryu Davis2018-06-041-2/+2
|
* bpo-33615: Re-enable a subinterpreter test. (gh-7251)Eric Snow2018-06-021-18/+37
| | | For bpo-32604 I added extra subinterpreter-related tests (see #6914), which caused a few buildbots to crash. This patch fixes the crash by ensuring that refcounts in channels are handled properly.
* bpo-32911: Add the historical note about the magic number. (GH-7273)Serhiy Storchaka2018-05-311-111/+111
|
* bpo-33677: Fix signatures of tp_clear handlers for AST and deque. (GH-7196)Serhiy Storchaka2018-05-311-1/+2
|
* bpo-33691: Add _PyAST_GetDocString(). (GH-7236)Serhiy Storchaka2018-05-304-58/+43
|
* bpo-32911: Revert bpo-29463. (GH-7121) (GH-7197)Serhiy Storchaka2018-05-297-3233/+3189
| | | | | | Remove the docstring attribute of AST types and restore docstring expression as a first stmt in their body. Co-authored-by: INADA Naoki <methane@users.noreply.github.com>
* bpo-33612: Remove PyThreadState_Clear() assertion (#7069)Victor Stinner2018-05-231-1/+0
| | | | | bpo-25612, bpo-33612: Remove an assertion from PyThreadState_Clear() which failed at Python shutdown or on fork if a thread was running a generator.
* bpo-23722: Raise a RuntimeError for absent __classcell__. (GH-6931)Serhiy Storchaka2018-05-201-15/+4
| | | A DeprecationWarning was emitted in Python 3.6-3.7.
* bpo-33475: Fix and improve converting annotations to strings. (GH-6774)Serhiy Storchaka2018-05-172-537/+291
|
* bpo-32604: Improve subinterpreter tests. (#6914)Eric Snow2018-05-161-3/+77
| | | Add more tests for subinterpreters. This patch also fixes a few small defects in the channel implementation.
* bpo-33509: Fix _warnings for module_globals=None (#6833)Victor Stinner2018-05-151-1/+8
| | | Don't crash on warnings.warn_explicit() if module_globals is not a dict.
* bpo-33443 Fix typo in Python/import.c (GH-6722)ukwksk2018-05-141-5/+5
|
* fix error message in ast.c (#6776)Jelle Zijlstra2018-05-131-1/+1
| | | small_stmt -> compound_stmt
* bpo-28055: Fix unaligned accesses in siphash24(). (GH-6123)Rolf Eike Beer2018-05-131-13/+13
| | | | | | | The hash implementation casts the input pointer to uint64_t* and directly reads from this, which may cause unaligned accesses. Use memcpy() instead so this code will not crash with SIGBUS on sparc. https://bugs.gentoo.org/show_bug.cgi?id=636400
* bpo-30465: Fix C downcast warning on Windows in ast.c (#6593)Victor Stinner2018-04-301-1/+1
| | | | ast.c: fstring_fix_node_location() downcasts a pointer difference to a C int. Replace int with Py_ssize_t to fix the compiler warning.
* bpo-33330: Write exceptions occurred in PyImport_Cleanup() to stderr. (GH-6606)Serhiy Storchaka2018-04-291-16/+20
| | | | They where silenced before.
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-293-18/+18
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.
* bpo-33363: raise SyntaxError for async for/with outside async functions (#6616)Zsolt Dollenstein2018-04-271-0/+7
|
* bpo-33334: Support NOP and EXTENDED_ARG in dis.stack_effect(). (#6566)Serhiy Storchaka2018-04-251-0/+4
| | | Added tests to ensure that all defined opcodes are supported.
* bpo-33330: Improve error handling in PyImport_Cleanup(). (GH-6564)Serhiy Storchaka2018-04-251-9/+24
|
* bpo-33128 Fix duplicated call to importlib._install_external_importers ↵Pablo Galindo2018-04-251-5/+0
| | | | | | | | | (GH-6273) External importers were being added in both phases of the import system initialisation. They're only supposed to be added in the second phase, after the import machinery has been appropriately configured.
* Spelling fixes to docs, docstrings, and comments (GH-6374)Ville Skyttä2018-04-202-3/+3
|
* bpo-33298: Wrap only constants with _PyCode_ConstantKey() in the compiler. ↵Serhiy Storchaka2018-04-201-104/+117
| | | | (GH-6512)
* bpo-33299: Return an object itself for some types in _PyCode_ConstantKey(). ↵Serhiy Storchaka2018-04-191-4/+6
| | | | (GH-6513)
* bpo-33270: Intern names for all anonymous code objects (#6472)Zackery Spytz2018-04-153-8/+8
|
* bpo-33169: Remove values of `None` from sys.path_importer_cache when ↵Brett Cannon2018-04-061-616/+618
| | | | | invalidating caches (GH-6402) An entry of None in sys.path_importer_cache represents a negative/missing finder for a path, so clearing it out makes sense.
* bpo-29673: fix gdb scripts pystack and pystackv (GH-6126)Marcel Plch2018-04-061-1/+1
|
* bpo-33231: Fix potential leak in normalizestring() (GH-6386)INADA Naoki2018-04-061-2/+0
|
* bpo-29922: Improve error messages in 'async with' (GH-6352)Serhiy Storchaka2018-04-021-0/+25
| | | when __aenter__() or __aexit__() return non-awaitable object.
* bpo-33132: Fix more reference counting issues in the compiler. (GH-6323)Serhiy Storchaka2018-03-311-4/+2
|
* bpo-33053: -m now adds *starting* directory to sys.path (GH-6231)Nick Coghlan2018-03-251-9/+21
| | | | | | | | | | | | Historically, -m added the empty string as sys.path zero, meaning it resolved imports against the current working directory, the same way -c and the interactive prompt do. This changes the sys.path initialisation to add the *starting* working directory as sys.path[0] instead, such that changes to the working directory while the program is running will have no effect on imports when using the -m switch.
* bpo-33042: Fix pre-initialization sys module configuration (GH-6157)Nick Coghlan2018-03-251-0/+162
| | | | | | | | | - new test case for pre-initialization of sys.warnoptions and sys._xoptions - restored ability to call these APIs prior to Py_Initialize - updated the docs for the affected APIs to make it clear they can be called before Py_Initialize - also enhanced the existing embedding test cases to check for expected settings in the sys module
* bpo-33132: Fix reference counting issues in the compiler. (GH-6209)Serhiy Storchaka2018-03-241-19/+12

* bpo-32932: More revealing error message when non-str objects in __all__ ↵Xiang Zhang2018-03-241-1/+27
| | | | (GH-5848)
* bpo-33041: Rework compiling an "async for" loop. (#6142)Serhiy Storchaka2018-03-234-209/+155
| | | | | | | | * Added new opcode END_ASYNC_FOR. * Setting global StopAsyncIteration no longer breaks "async for" loops. * Jumping into an "async for" loop is now disabled. * Jumping out of an "async for" loop no longer corrupts the stack. * Simplify the compiler.
* bpo-32489: Allow 'continue' in 'finally' clause. (GH-5822)Serhiy Storchaka2018-03-181-4/+0
|
* bpo-33021: Release the GIL during fstat() calls (GH-6019)Nir Soffer2018-03-111-1/+6
| | | | | | | | | | | | | | fstat may block for long time if the file descriptor is on a non-responsive NFS server, hanging all threads. Most fstat() calls are handled by _Py_fstat(), releasing the GIL internally, but but _Py_fstat_noraise() does not release the GIL, and most calls release the GIL explicitly around it. This patch fixes last 2 calls to _Py_fstat_no_raise(), avoiding hangs when calling: - mmap.mmap() - os.urandom() - random.seed()
* Drop confusing commented out code in pystrtod.c (GH-6072)Siddhesh Poyarekar2018-03-111-2/+0
|
* bpo-32925: Optimized iterating and containing test for literal lists (GH-5842)Serhiy Storchaka2018-03-111-2/+17
| | | | | consisting of non-constants: `x in [a, b]` and `for x in [a, b]`. The case of all constant elements already was optimized.
* bpo-32946: Speed up "from ... import ..." from non-packages. (GH-5873)Serhiy Storchaka2018-03-112-262/+273
|
* bpo-33041: Add missed error checks when compile "async for" (#6053)Serhiy Storchaka2018-03-101-14/+7
| | | and remove redundant code.
* bpo-33041: Fixed bytecode generation for "async for" with a complex target. ↵Serhiy Storchaka2018-03-101-2/+2
| | | | | | (#6052) A StopAsyncIteration raised on assigning or unpacking will be now propagated instead of stopping the iteration.
* Add two missing error checks in hamt.c (GH-5851)Xiang Zhang2018-03-081-1/+7
|
* bpo-33005: Fix _PyGILState_Reinit() (#6001)Victor Stinner2018-03-061-4/+23
| | | | | | | | Fix a crash on fork when using a custom memory allocator (ex: using PYTHONMALLOC env var). _PyGILState_Reinit() and _PyInterpreterState_Enable() now use the default RAW memory allocator to allocate a new interpreters mutex on fork.
* Fix strncpy warning with gcc 8 (#5840)Siddhesh Poyarekar2018-03-061-2/+2
| | | | | The length in strncpy is one char too short and as a result it leads to a build warning with gcc 8. Comment out the strncpy since the interpreter aborts immediately after anyway.
* closes bpo-32980 Remove _PyFrame_Init (GH-5965)Thomas Nyberg2018-03-041-3/+0
