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 17b53f1301 asyncio: Handle error handler: enhance formatting of the callback 2014-06-26 01:35:45 +02:00
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 f328c7dc69 asyncio, Tulip issue 171: BaseEventLoop.close() now raises an exception if the

it stopped, before closing it.

Victor Stinner d6de5d8455 asyncio: BaseEventLoop._assert_is_current_event_loop() now only raises an
exception if the current loop is not None.

Guido van Rossum wrote:

"The behavior that you can set the loop to None (and keep track of it
explicitly) is part of the spec, and this should still be supported even in
debug mode. The behavior that we raise an error if you are caught having
multiple active loops per thread is just a debugging heuristic, and it
shouldn't break code that follows the spec."

Victor Stinner d143209d7f Tulip issue 83: document more asyncio functions in docstrings 2014-06-19 17:11:49 +02:00
Victor Stinner 54c4b8e5c1 Closes #21595: asyncio.BaseSelectorEventLoop._read_from_self() now reads all
available bytes from the "self pipe", not only a single byte. This change
reduces the risk of having the pipe full and so getting the innocuous
"BlockingIOError: [Errno 11] Resource temporarily unavailable" message.

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 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.

Victor Stinner bb2fc5b2a5 Issue #21326: Add a new is_closed() method to asyncio.BaseEventLoop
Add BaseEventLoop._closed attribute and use it to check if the event loop was
closed or not, instead of checking different attributes in each subclass of
BaseEventLoop.

run_forever() and run_until_complete() methods now raise a RuntimeError('Event loop is
closed') exception if the event loop was closed.

BaseProactorEventLoop.close() now also cancels "accept futures".

* 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
