3b43bfa Update docs for 3.7.0a4 09 January 2018, 02:57:13 UTC
ca0c5f2 bpo-32248: install new test_importlib directories (#5138) 09 January 2018, 02:07:59 UTC
9b99747 bpo-31975 (PEP 565): Show DeprecationWarning in __main__ (GH-4458) - primary change is to add a new default filter entry for 'default::DeprecationWarning:__main__' - secondary change is an internal one to cope with plain strings in the warning module's internal filter list (this avoids the need to create a compiled regex object early on during interpreter startup) - assorted documentation updates, including many more examples of configuring the warnings settings - additional tests to ensure that both the pure Python and the C accelerated warnings modules have the expected default configuration 08 January 2018, 02:45:02 UTC
d138892 bpo-32506: Change dataclasses from OrderedDict to plain dict. (gh-5131) 07 January 2018, 19:30:17 UTC
b216a25 Fix version in AppVeyor config (GH-5124) 07 January 2018, 18:59:48 UTC
3460198 bpo-31802: Fix importing native path module before importing os. (#4017) 07 January 2018, 15:54:31 UTC
e46a8af bpo-30579: Allow TracebackType creation and tb_next mutation from Python (GH-4793) Third party projects may wish to hide their own internal machinery in order to present more comprehensible tracebacks to end users (e.g. Jinja2 and Trio both do this). Previously such projects have had to rely on ctypes to do so: https://github.com/pallets/jinja/blob/fe3dadacdf4cf411d0a5b6bbd4d5234697a28af2/jinja2/debug.py#L345 https://github.com/python-trio/trio/blob/1e86b1aee8c0c759f6f239ae53a05d0d3963c629/trio/_core/_multierror.py#L296 This provides a Python level API for creating and modifying real Traceback objects, allowing tracebacks to be edited at runtime. Patch by Nathaniel Smith. 07 January 2018, 13:30:18 UTC
d327ae6 Fix dataclasses docstring typo. (gh-5118) 07 January 2018, 13:19:45 UTC
7f7de37 Kill the AppVeyor file whitelist (GH-5121) It's more trouble than it's worth, since AppVeyor only checks the HEAD commit of a PR rather than the full diff against the base branch to decide which files changed. 07 January 2018, 02:41:17 UTC
af11a15 bpo-32282: Remove unnecessary check for `VersionHelpers.h` in `socketmodule.c` on Windows 07 January 2018, 02:05:18 UTC
d80b443 bpo-32279: Add additional params to make_dataclass(), pass through to dataclass(). (gh-5117) 06 January 2018, 22:09:58 UTC
ed7d429 bpo-32278: Allow dataclasses.make_dataclass() to omit type information. (gh-5115) 06 January 2018, 21:14:03 UTC
e7ba013 bpo-32499: Add dataclasses.is_dataclass(obj), which returns True if obj is a dataclass or an instance of one. (#5113) 06 January 2018, 17:41:53 UTC
3cd7c6e bpo-31993: Do not allocate large temporary buffers in pickle dump. (#4353) The picklers do no longer allocate temporary memory when dumping large bytes and str objects into a file object. Instead the data is directly streamed into the underlying file object. Previously the C implementation would buffer all content and issue a single call to file.write() at the end of the dump. With protocol 4 this behavior has changed to issue one call to file.write() per frame. The Python pickler with protocol 4 now dumps each frame content as a memoryview to an IOBytes instance that is never reused and the memoryview is no longer released after the call to write. This makes it possible for the file object to delay access to the memoryview of previous frames without forcing any additional memory copy as was already possible with the C pickler. 06 January 2018, 15:18:54 UTC
85ac726 Cleanup grammar in unittest.mock.seal documentation (#5107) 06 January 2018, 13:25:34 UTC
9f1e5f1 bpo-32206: Pdb can now run modules (GH-4752) Add a new argument "-m" to the pdb module to allow users to run `python -m pdb -m my_module_name`. This relies on private APIs in the runpy module to work, but we can get away with that since they're both part of the standard library and can be updated together if the runpy internals get refactored. 06 January 2018, 07:53:05 UTC
735ae8d bpo-29137: Remove fpectl module (#4789) This module has never been enabled by default, never worked correctly on x86-64, and caused ABI problems that caused C extension compatibility. See bpo-29137 for details/discussion. 06 January 2018, 07:15:34 UTC

94459fd bpo-31699 Deadlocks in `concurrent.futures.ProcessPoolExecutor` with pickling error (#3895) Fix deadlocks in :class:`concurrent.futures.ProcessPoolExecutor` when task arguments or results cause pickling or unpickling errors. This should make sure that calls to the :class:`ProcessPoolExecutor` API always eventually return. 05 January 2018, 10:15:54 UTC

78e24d4 Fix outdated comment in typeobject.c (GH-5090) The comment was added in 3abca127fe1565ec80f6b0a1ae48d65186ad887d. In d78448e912126410117723c7d240bbdfff06df16, it was changed to use PyArg_ParseTuple instead. 04 January 2018, 10:24:45 UTC

0d3ccb4 bpo-32399: Starting with AIX6.1 there is support in libc.a for uuid (RFC4122) (#4974) Starting with AIX6.1 there is support in libc.a for uuid (RFC4122) This patch provides the changes needed for this integration with the OS. On AIX the base function is uuid_create() rather than uuid_generate_time() The AIX uuid_t typedef is more aligned to the UUID field based definition while the Linux typedef that is more aligned with UUID bytes (or perhaps UUID bytes_le) definitions. 30 December 2017, 21:39:20 UTC

8a58771 bpo-24960: use pkgutil.get_data in lib2to3 to read pickled grammar files (#4977) This is more complicated than it should be because we need to preserve the useful mtime-based regeneration feature that lib2to3.pgen2.driver.load_grammar has. We only look for the pickled grammar file with pkgutil.get_data and only if the source file does not exist. 22 December 2017, 20:18:33 UTC

424315f bpo-29240: Skip test_readline.test_nonascii() (#4968) Skip the test which fails on FreeBSD with POSIX locale. Skip the test to fix FreeBSD buildbots, until a fix can be found, so the buildbots can catch other regressions. 21 December 2017, 23:09:26 UTC
550ee05 bpo-20891: Skip test_embed.test_bpo20891() (#4967) Skip the test failing randomly because of known race condition. Skip the test to fix macOS buildbots until a decision is made on the proper fix for the race condition. 21 December 2017, 23:05:05 UTC
9bee329 bpo-32030: Add _Py_FindEnvConfigValue() (#4963) Add a new _Py_FindEnvConfigValue() function: code shared between Windows and Unix implementations of _PyPathConfig_Calculate() to read the pyenv.cfg file. _Py_FindEnvConfigValue() now uses _Py_DecodeUTF8_surrogateescape() instead of using a Python Unicode string, the Python API must not be used early during Python initialization. Same change in Unix search_for_exec_prefix(): use _Py_DecodeUTF8_surrogateescape(). Cleanup also encode_current_locale(): PyMem_RawFree/PyMem_Free can be called with NULL. Fix also "NUL byte" => "NULL byte" typo. 21 December 2017, 15:49:13 UTC
9dd7620 bpo-32030: Add _Py_EncodeLocaleRaw() (#4961) Replace Py_EncodeLocale() with _Py_EncodeLocaleRaw() in: * _Py_wfopen() * _Py_wreadlink() * _Py_wrealpath() * _Py_wstat() * pymain_open_filename() These functions are called early during Python intialization, only the RAW memory allocator must be used. 21 December 2017, 15:20:32 UTC

e47e698 bpo-32030: Add _Py_EncodeUTF8_surrogateescape() (#4960) Py_EncodeLocale() now uses _Py_EncodeUTF8_surrogateescape(), instead of using temporary unicode and bytes objects. So Py_EncodeLocale() doesn't use the Python C API anymore. 21 December 2017, 14:45:16 UTC

Changes: * _PyCoreConfig: Add nxoption, xoptions, nwarnoption and warnoptions * Add _PyCoreConfig.program: argv[0] or "" * Move filename, command, module and xoptions from _Py_CommandLineDetails to _PyMain. xoptions _Py_OptList becomes (int, wchar_t**) list. * Add pymain_cmdline() function * Rename copy_argv() to copy_wstrlist(). Rename clear_argv() to clear_wstrlist(). Remove _Py_OptList structure: use (int, wchar_t**) list instead. * Rename pymain_set_flag_from_env() to pymain_get_env_flag() * Rename pymain_set_flags_from_env() to pymain_get_env_flags() * _PyMainInterpreterConfig_Read() now creates the warnoptions from _PyCoreConfig.warnoptions * Inline pymain_add_warning_dev_mode() and pymain_add_warning_bytes_flag() into config_init_warnoptions() * Inline pymain_get_program_name() into _PyCoreConfig_Read() * _Py_CommandLineDetails: Replace warning_options with nwarnoption and warnoptions. Replace env_warning_options with nenv_warnoption and env_warnoptions. * pymain_warnings_envvar() now has a single implementation for Windows and Unix: use config_get_env_var_dup() to also get the variable as wchar_t* on Unix. 20 December 2017, 17:00:19 UTC
