Victor Stinner 6cf5c96630 Issue #20505: BaseEventLoop uses again the resolution of the clock to decide if 
scheduled tasks should be executed or not.
 2014-02-10 23:42:32 +01:00
Victor Stinner 1c143b19c8 Issue #20505: Add debug info to analyze sporaric failures of

Victor Stinner 83bdfa08f7 asyncio: Fix _ProactorWritePipeTransport._pipe_closed() 
Do nothing if the pipe is already closed. _loop_writing() may call
_force_close() when it gets ConnectionResetError.
 2014-02-04 08:57:48 +01:00
Victor Stinner b79eb0502c asyncio.subprocess: Replace Process.get_subprocess() method with a 
Process.subprocess read-only property
 2014-02-03 23:08:14 +01:00
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 1506df2655 Issue #20455: Add a resolution attribute to IocpProactor (1 ms) 2014-01-31 16:26:38 +01:00
Victor Stinner f2e1768bc1 Issue #20455: asyncio: use the same code to round a timeout than the selectors 
module

Sort also imports
 2014-01-31 16:25:24 +01:00
Victor Stinner b60e9ca69d Issue #20455: asyncio: write a new write pipe transport class for proactor (on 
Windows) instead of using the "duplex" pipe transport. The new class uses a
simpler overlapped read to be notified when the pipe is closed. So the protocol
doesn't need to implement eof_received(): connection_lost() is called instead.
_UnixWritePipeTransport has the same approach.
 2014-01-31 14:18:18 +01:00
Victor Stinner 61b3c9bacc asyncio: Fix _UnixWritePipeTransport, raise BrokenPipeError when the pipe is 
closed, but only if there was pending write
 2014-01-31 13:04:28 +01:00

 2014-01-26 00:02:31 +01:00
Victor Stinner 128ee220e2 asyncio: Don't export BaseEventLoop, BaseSelectorEventLoop nor 
BaseProactorEventLoop

Import them from submodules if you really need them.
 2014-01-25 22:22:18 +01:00
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

Victor Stinner 75a5ec88ff Fix asyncio tests: define resolution 2014-01-25 15:31:06 +01:00
Victor Stinner f67255ab94 Issue #20311: asyncio: Add a granularity attribute to BaseEventLoop: maximum 
between the resolution of the BaseEventLoop.time() method and the resolution of
the selector. The granuarility is used in the scheduler to round time and
deadline.
 2014-01-25 15:01:33 +01:00
Victor Stinner 421e49b5c1 asyncio: wait_for() now cancels the future on timeout. Patch written by Gustavo

Victor Stinner 183e347796 asyncio (Tulip issue 110): StreamReader.read() and StreamReader.readline() now

Victor Stinner 3eb45d3eae asyncio: Fix open_connection() documentation, writer is a StreamWriter 2014-01-23 10:20:18 +01:00
Victor Stinner 4a2dbeb0d3 asyncio: Cleanup logging in BaseEventLoop._run_once() 
logger.log() is now responsible to format the timeout. It might be faster if
the log is disabled for DEBUG level, but it's also more readable and fix
an issue with Python 2.6 in the Trollius project.
 2014-01-22 12:26:01 +01:00
Victor Stinner 22463aa947 Close #20275: Optimize BaseEventLoop._run_once() 
Logger.log() is "slow", logger.isEnabledFor() is faster and the logger is
disabled in most cases. A microbenchmark executing 100,000 dummy tasks is 22%
faster with this change.

__slot__ => __slots__
 2014-01-16 01:38:24 +01:00
Victor Stinner 7de2646cdf Cleanup properly proactor event loop 
* store the "self reading" future when the "self pipe" is closed (when the
  event loop is closed)
* store "accept" futures to cancel them when we stop serving
* close the "accept socket" if the "accept future" is cancelled

Fix many warnings which can be seen when unit tests are run in verbose mode.
