[issue35826] Typo in example for async with statement with condition
by Kevin Mai-Hsuan Chia 11 Oct '19

11 Oct '19

New submission from Kevin Mai-Hsuan Chia <kevin(a)mhchia.com>: In the [example](https://docs.python.org/3.8/library/asyncio-sync.html#asyncio.Cond… of the equivalent code to the `async with statement`: ```python cond = asyncio.Condition() # ... later await lock.acquire() try: await cond.wait() finally: lock.release() ``` `lock.acquire()` should be replaced by `cond.acquire()`, and `lock.release()` replaced by `cond.release()`. So the resulting code snippet becomes: ```python cond = asyncio.Condition() # ... later await cond.acquire() try: await cond.wait() finally: cond.release() ``` ---------- assignee: docs@python components: Documentation messages: 334349 nosy: docs@python, mhchia priority: normal severity: normal status: open title: Typo in example for async with statement with condition type: enhancement versions: Python 3.8 _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue35826> _______________________________________

[issue17894] Edits to descriptor howto
by Ned Batchelder 10 Oct '19

10 Oct '19

New submission from Ned Batchelder: I find the explanations in the Descriptor howto to be difficult to understand. I took a stab at changing the first few sections to introduce the concepts in an easier-to-grasp style. Issue 12077 also covers a little bit of this. ---------- assignee: docs@python components: Documentation files: descriptor_howto.patch keywords: patch messages: 188289 nosy: docs@python, nedbat priority: normal severity: normal status: open title: Edits to descriptor howto versions: Python 3.4 Added file: http://bugs.python.org/file30111/descriptor_howto.patch _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue17894> _______________________________________

[issue13322] The io module doesn't support non-blocking files
by STINNER Victor 10 Oct '19

10 Oct '19

STINNER Victor <vstinner(a)python.org> added the comment: TextIOWrapper, and maybe also BufferedRead, may raise an exception if the underlying file descriptor is configured in non-blocking mode. It may require an additional syscall() to query the FD properties, which may slowdown the creation of file objects in Python :-/ ---------- _______________________________________ Python tracker <report(a)bugs.python.org> <https://bugs.python.org/issue13322> _______________________________________
