Yury Selivanov 600a349781 Issue #28613: Fix get_event_loop() to return the current loop
when called from coroutines or callbacks.

Victor Stinner e6ecea53c8 asyncio: sync with github asyncio

Yury Selivanov 59eb9a4da5 asyncio: async() function is deprecated in favour of ensure_future(). 2015-05-11 14:48:38 -04:00
Victor Stinner e0fd157ba0 Issue #23293, asyncio: Rewrite IocpProactor.connect_pipe() as a coroutine
Use a coroutine with asyncio.sleep() instead of call_later() to ensure that the
schedule call is cancelled.

Add also a unit test cancelling connect_pipe().

Victor Stinner fea6a100dc asyncio: sync with Tulip
Improve stability of the proactor event loop, especially operations on
overlapped objects:

* Tulip issue 195: Don't call UnregisterWait() twice if a _WaitHandleFuture is
  cancelled twice to fix a crash.
* IocpProactor.close(): cancel futures to cancel overlapped operations, instead
  of cancelling directly overlapped operations. Future objects may not call
  ov.cancel() if the future was cancelled or if the overlapped was already
  cancelled. The cancel() method of the future may also catch exceptions. Log
  also errors on cancellation.
* tests: rename "f" to "fut"
* Add a __repr__() method to IocpProactor
* Add a destructor to IocpProactor which closes it
* _OverlappedFuture.cancel() doesn't cancel the overlapped anymore if it is
  done: if it is already cancelled or completed. Log also an error if the
  cancellation failed.
* Add the address of the overlapped object in repr(_OverlappedFuture)
* _OverlappedFuture truncates the source traceback to hide the call to the
  parent constructor (useless in debug).

Victor Stinner 915bcb0111 Issue #20400: Merge Tulip into Python: add the new asyncio.subprocess module
* Add a new asyncio.subprocess module
* Add new create_subprocess_exec() and create_subprocess_shell() functions
* The new asyncio.subprocess.SubprocessStreamProtocol creates stream readers
  for stdout and stderr and a stream writer for stdin.
* The new asyncio.subprocess.Process class offers an API close to the
  subprocess.Popen class:

  - pid, returncode, stdin, stdout and stderr attributes
  - communicate(), wait(), send_signal(), terminate() and kill() methods

* Remove STDIN (0), STDOUT (1) and STDERR (2) constants from base_subprocess
  and unix_events, to not be confused with the symbols with the same name of
  subprocess and asyncio.subprocess modules
* _ProactorBasePipeTransport.get_write_buffer_size() now counts also the size
  of the pending write
* _ProactorBaseWritePipeTransport._loop_writing() may now pause the protocol if
  the write buffer size is greater than the high water mark (64 KB by default)

Victor Stinner 8dffc456d7 Update asyncio from the Tulip project
Major changes:

- StreamReader.readexactly() now raises an IncompleteReadError if the
  end of stream is reached before we received enough bytes, instead of
  returning less bytes than requested.

- Unit tests use the main asyncio module instead of submodules like events

- _UnixWritePipeTransport now also supports character devices, as
  _UnixReadPipeTransport. Patch written by Jonathan Slenders.

- Export more symbols: BaseEventLoop, BaseProactorEventLoop,
  BaseSelectorEventLoop, Queue and Queue sublasses, Empty, Full
