* bpo-32576: use queue.SimpleQueue in critical places (#5216)Antoine Pitrou2018-01-182-9/+12
| | | | Where a queue may be invoked from a weakref callback, we need to use the reentrant SimpleQueue.
* Use assertCountEqual instead of assertEqual. (#5223)Gregory P. Smith2018-01-171-3/+3
| | | | This test doesn't care about order, the underlying filesystem APIs do not guarantee directory listings on subsequent calls will be in the same order.
* pythoninfo: add time.time and datetime.datetime.now (#5214)Victor Stinner2018-01-171-1/+13
|
* bpo-32248: Fix test_importlib.test_open() (#5213)Victor Stinner2018-01-171-2/+2
| | | | Use the binary.file instead of utf-8.file to avoid issues with Unix newlines vs Windows newlines.
* bpo-32403: Faster date and datetime constructors (#4993)Paul Ganssle2018-01-161-0/+92
| | | | | | | | | | | | | | * Add tests for date subclass alternate constructors * Switch over alternate date constructors to fast path * Switch datetime constructors to fastpath, fix bpo-32404 * Add fast path for datetime in date subclass constructor * Set fold in constructor in datetime.combine * Add news entries.
* bpo-32410: Implement loop.sock_sendfile() (#4976)Andrew Svetlov2018-01-166-0/+578
|
* Skip test_readline.test_nonascii() on C locale (#5203)Victor Stinner2018-01-161-0/+8
| | | | | bpo-29240: On FreeBSD, if the LC_CTYPE locale is "C" or "POSIX", writing and reading non-ASCII bytes into/from a TTY works, but readline or ncurses ignores non-ASCII bytes on read.
* bpo-14976: Reentrant simple queue (#3346)Antoine Pitrou2018-01-152-8/+318
| | | | Add a queue.SimpleQueue class, an unbounded FIFO queue with a reentrant C implementation of put().
* Implement the get_resource_reader() API for file system imports (#5168)Barry Warsaw2018-01-155-10/+44
|
* Make asyncio tests run when there's no SSL module (#5196)Yury Selivanov2018-01-151-3/+0

* Add itertools recipe for directly finding the n-th combination (#5161)Raymond Hettinger2018-01-131-0/+33

* bpo-32248: Introduce the concept of Loader.get_resource_reader() (GH-5108)Brett Cannon2018-01-121-2/+7
|
* bpo-31993: Do not use memoryview when pickle large strings. (#5154)Serhiy Storchaka2018-01-121-30/+30
| | | | | | PyMemoryView_FromMemory() created a memoryview referring to the internal data of the string. When the string is destroyed the memoryview become referring to a freed memory.
* bpo-32473: Improve ABCMeta._dump_registry() readability (GH-5091)yahya-abou-imran2018-01-121-1/+3
|
* OrderedDict import is no longer needed (#4890)Raymond Hettinger2018-01-121-2/+1
|
* bpo-32467: Let collections.abc.ValuesView inherit from Collection (#5152)Raymond Hettinger2018-01-122-3/+3
|
* bpo-31113: Get rid of recursion in the compiler for normal control flow. (#3015)Serhiy Storchaka2018-01-111-0/+5
|
* bpo-31993: Do not create frames for large bytes and str objects (#5114)Serhiy Storchaka2018-01-112-10/+11
| | | | | | | when serialize into memory buffer with C pickle implementations. This optimization already is performed when serialize into memory with Python pickle implementations or into a file with both implementations.
* bpo-32320: Add default value support to collections.namedtuple() (#4859)Raymond Hettinger2018-01-112-3/+68
|
* Fix obvious typos in docstrings (#5151)Raymond Hettinger2018-01-111-6/+7
|
* bpo-29240: readline now ignores the UTF-8 Mode (#5145)Victor Stinner2018-01-101-2/+0
| | | | | | | | | | | | Add new fuctions ignoring the UTF-8 mode: * _Py_DecodeCurrentLocale() * _Py_EncodeCurrentLocale() * _PyUnicode_DecodeCurrentLocaleAndSize() * _PyUnicode_EncodeCurrentLocale() Modify the readline module to use these functions. Re-enable test_readline.test_nonascii().
* Fix when parsing tz offsets microseconds shorter than 6 (#4781)Mario Corchero2018-01-092-1/+7
| | | | As the remainder was directly parsed as an int, strings like .600 were parsed as 600 microseconds rather than milliseconds.
* bpo-24340: Fix estimation of the code stack size. (#5076)Serhiy Storchaka2018-01-092-9/+298

* Update docs for 3.7.0a4Ned Deily2018-01-091-156/+272

* bpo-31975 (PEP 565): Show DeprecationWarning in __main__ (GH-4458)Nick Coghlan2018-01-083-2/+40
| | | | | | | | | | | | | - 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
* bpo-32506: Change dataclasses from OrderedDict to plain dict. (gh-5131)Eric V. Smith2018-01-071-8/+8

* bpo-31802: Fix importing native path module before importing os. (#4017)Serhiy Storchaka2018-01-074-32/+40

* bpo-30579: Allow TracebackType creation and tb_next mutation from Python ↵Nathaniel J. Smith2018-01-071-0/+66
| | | | | | | | | | | | | | | | | (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.

* bpo-31993: Do not allocate large temporary buffers in pickle dump. (#4353)Olivier Grisel2018-01-064-26/+169
| | | | | | | | | | | | | | | | | 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.
* bpo-32206: Pdb can now run modules (GH-4752)Mario Corchero2018-01-062-21/+173
| | | | | | | | | | | 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.

| | | | | | 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.
