Yury Selivanov 1af2bf75a2 asyncio: Support PEP 492. Issue #24017. 2015-05-11 22:27:25 -04:00
Yury Selivanov 59eb9a4da5 asyncio: async() function is deprecated in favour of ensure_future(). 2015-05-11 14:48:38 -04:00
Victor Stinner 2934262fd3 asyncio: sync with Tulip
* Cleanup gather(): use cancelled() method instead of using private Future
  attribute
* Fix _UnixReadPipeTransport and _UnixWritePipeTransport. Only start reading
  when connection_made() has been called.
* Issue #23333: Fix BaseSelectorEventLoop._accept_connection(). Close the
  transport on error. In debug mode, log errors using call_exception_handler()

Victor Stinner 922bc2ca12 Closes #23219: cancelling asyncio.wait_for() now cancels the task 2015-01-15 16:29:10 +01:00
Victor Stinner 3531d9044d asyncio: sync with Tulip
* Document why set_result() calls are safe
* Cleanup gather(). Use public methods instead of hacks to consume the
  exception of a future.
* sock_connect(): pass directly the fd to _sock_connect_done instead of the
  socket.

Victor Stinner fe22e0985a asyncio: Initialize more Future and Task attributes in the class definition to
avoid attribute errors in destructors.

Also fixed the phrasing in a comment.

Victor Stinner 59e0802301 asyncio, Tulip issue 201: Fix a race condition in wait_for()
Don't raise a TimeoutError if we reached the timeout and the future completed
in the same iteration of the event loop. A side effect of the bug is that
Queue.get() looses items.

Victor Stinner 313a980904 asyncio: sync with Tulip
* _WaitHandleFuture.cancel() now notify IocpProactor through the overlapped
  object that the wait was cancelled.
* Optimize IocpProactor.wait_for_handle() gets the result if the wait is
  signaled immediatly.
* Enhance representation of Future and Future subclasses

  - Add "created at filename:lineno" in the representation
  - Add Future._repr_info() method which can be more easily overriden than
    Future.__repr__(). It should now be more easy to enhance Future
    representation without having to modify each subclass. For example,
    _OverlappedFuture and _WaitHandleFuture get the new "created at" information.
  - Use reprlib to format Future result, and function arguments when formatting a
    callback, to limit the length of the representation.

* Fix repr(_WaitHandleFuture)
* _WaitHandleFuture and _OverlappedFuture: hide frames of internal calls in the
  source traceback.
* Cleanup ProactorIocp._poll(): set the timeout to 0 after the first call to
  GetQueuedCompletionStatus()
* test_locks: close the temporary event loop and check the condition lock
* Remove workaround in test_futures, no more needed

Victor Stinner e931f7b768 Issue #21163: Fix "destroy pending task" warning in test_wait_errors() 2014-07-16 18:50:39 +02:00
Victor Stinner f03b3c7564 Issue #21163, asyncio: Ignore "destroy pending task" warnings for private tasks
in gather().

Victor Stinner 770e48d017 asyncio: sync with Tulip
* Tulip issue #182: Improve logs of BaseEventLoop._run_once()

  - Don't log non-blocking poll
  - Only log polling with a timeout if it gets events or if it timed out after
    more than 1 second.

* Fix some pyflakes warnings: remove unused imports

Victor Stinner 737c34fa85 asyncio: sync with Tulip
- CoroWrapper.__del__() now reuses repr(CoroWrapper) to log the "... was never
  yielded from" warning
- Improve CoroWrapper: copy also the qualified name on Python 3.4, not only on
  Python 3.5+
2014-07-11 01:04:16 +02:00
Victor Stinner c39ba7d611 asyncio: sync with Tulip
- repr(Task) and repr(CoroWrapper) now also includes where these objects were
  created. If the coroutine is not a generator (don't use "yield from"), use
  the location of the function, not the location of the coro() wrapper.
- Fix create_task(): truncate the traceback to hide the call to create_task().
2014-07-11 00:21:27 +02:00
Victor Stinner 896a25ab30 asyncio: sync with Tulip
- Tulip issue 185: Add a create_task() method to event loops. The create_task()
  method can be overriden in custom event loop to implement their own task
  class. For example, greenio and Pulsar projects use their own task class. The
  create_task() method is now preferred over creating directly task using the
  Task class.
- tests: fix a warning
- fix typo in the name of a test function
- Update AbstractEventLoop: add new event loop methods; update also the unit test

Victor Stinner a9acbe82e7 Closes #21886, #21447: Fix a race condition in asyncio when setting the result
of a Future with call_soon(). Add an helper, a private method, to set the
result only if the future was not cancelled.
2014-07-05 15:29:41 +02:00
Victor Stinner 2dba23af71 asyncio: sync with Tulip
* _UnixSubprocessTransport: fix file mode of stdin. Open stdin in write mode,
  not in read mode
* Examples: close the event loop at exit
* More reliable CoroWrapper.__del__. If the constructor is interrupted by
  KeyboardInterrupt or the coroutine objet is destroyed lately, some the
  _source_traceback attribute doesn't exist anymore.
* repr(Task): include also the future the task is waiting for
2014-07-03 00:59:00 +02:00
Victor Stinner 98b6391fd4 Issue #21163: BaseEventLoop.run_until_complete() and test_utils.run_briefly()
don't log the "destroy pending task" message anymore. The log is redundant for
run_until_complete() and useless in run_briefly().
2014-06-30 14:51:04 +02:00
Victor Stinner f951d28ac8 asyncio: sync with Tulip, add a new asyncio.coroutines module 2014-06-29 00:46:45 +02:00
Victor Stinner 80f53aa9a0 asyncio, Tulip issue 137: In debug mode, save traceback where Future, Task and
Handle objects are created. Pass the traceback to call_exception_handler() in
the 'source_traceback' key.

The traceback is truncated to hide internal calls in asyncio, show only the
traceback from user code.

Add tests for the new source_traceback, and a test for the 'Future/Task
exception was never retrieved' log.

Victor Stinner bbd96c6f47 asyncio, Tulip issue 137: In debug mode, add the traceback where the coroutine
object was created to the "coroutine ... was never yield from" log

Victor Stinner 975735f729 asyncio, Tulip issue 177: Rewite repr() of Future, Task, Handle and TimerHandle
- Uniformize repr() output to format "<Class ...>"
- On Python 3.5+, repr(Task) uses the qualified name instead of the short name
  of the coroutine
2014-06-25 21:41:58 +02:00
Victor Stinner df29c4a83d asyncio: repr(Task) now also contains the line number even if the coroutine is
done: use the first line number of the code object instead of the current line
number of the generator frame.

The name of the coroutine is not enough because many coroutines may have the
same name. It's a common case in asyncio tests for example.

Victor Stinner 8d3e02ef5a asyncio: Set __qualname__ attribute of CoroWrapper in @coroutine decorator on
Python 3.5

- Drop __slots__ optimization of CoroWrapper to be able to set the __qualname__
  attribute.
- Add tests on __name__, __qualname__ and __module__ of a coroutine function
  and coroutine object.
- Fix test_tasks when run in debug mode (PYTHONASYNCIODEBUG env var set) on
  Python 3.3 or 3.4

Victor Stinner bc434e2052 asyncio: Task.__repr__() now also handles CoroWrapper 2014-06-17 00:26:36 +02:00
Victor Stinner 307bccc6ff asyncio: Tulip issue 173: Enhance repr(Handle) and repr(Task)
repr(Handle) is shorter for function: "foo" instead of "<function foo at
0x...>". It now also includes the source of the callback, filename and line
number where it was defined, if available.

repr(Task) now also includes the current position in the code, filename and
line number, if available. If the coroutine (generator) is done, the line
number is omitted and "done" is added.
