* asyncio: Remove asyncio/compat.py (#4606)Victor Stinner2017-11-281-2/+1
| | | | | | | | | | The asyncio/compat.py file was written to support Python < 3.5 and Python < 3.5.2. But Python 3.5 doesn't accept bugfixes anymore, only security fixes. There is no more need to backport bugfixes to Python 3.5, and so no need to have a single code base for Python 3.5, 3.6 and 3.7. Say hello (again) to "async" and "await", who became real keywords in Python 3.7 ;-)
* bpo-31556: asyncio.wait_for can cancel futures faster with timeout <= 0 (#3703)Victor K2017-10-051-0/+9
|
* bpo-30508: Don't log exceptions if Task/Future "cancel()" method called (#2050)Yury Selivanov2017-06-111-0/+1
|
* bpo-30048: asyncio: fix Task.cancel() was ignored. (GH-1097)INADA Naoki2017-05-111-1/+6
| | | | | | | | | | | | when there are no more `await` or `yield (from)` before return in coroutine, cancel was ignored. example: async def coro(): asyncio.Task.current_task().cancel() return 42 ... res = await coro() # should raise CancelledError
* bpo-29617: Remove Python 3.3 support from asyncio (GH-232)INADA Naoki2017-04-251-14/+10

* bpo-30098: Clarify that run_coroutine_threadsafe expects asyncio.Future ↵Charles Renwick2017-04-211-1/+2

* | Issue #28544: Implement asyncio.Task in C.Yury Selivanov2016-10-281-64/+16
|/ | | | | | | | This implementation provides additional 10-20% speed boost for asyncio programs. The patch also fixes _asynciomodule.c to use Arguments Clinic, and makes '_schedule_callbacks' an overridable method (as it was in 3.5).
* Issue #26923: Fix asyncio.Gather to refuse being cancelled once all children ↵Yury Selivanov2016-10-211-2/+4
| | | | | | are done. Patch by Johannes Ebke.

|
* Rename Future._blocking to _asyncio_future_blocking.Guido van Rossum2016-09-091-3/+4
| | | | | | | | | | | | This is now an official "protected" API that can be used to write classes that are duck-type-compatible with Future without subclassing it. (For that purpose I also changed isinstance(result, Future) to check for this attribute instead.) Hopefully Amber Brown can use this to make Twisted.Deferred compatible with asyncio.Future. Tests and docs are TBD.
* asyncio: Remove asyncio.timeout() context manager.Yury Selivanov2016-06-081-53/+0
| | | | | | | It will probably be added back in Python 3.6, once its compatibility issues are resolved; see [1] for more details. [1] https://mail.python.org/pipermail/async-sig/2016-June/000045.html
