[issue19973] Deprecate pyio
New submission from Larry Hastings: Does it make sense to finally deprecate pyio, so we can eventually delete it? -- messages: 206060 nosy: larry priority: normal severity: normal status: open title: Deprecate pyio versions: Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19973 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue19973] Deprecate pyio
STINNER Victor added the comment: I like the _pyio module! It's useful to test some new features. For example, I'm using it to identify where a file is destroyed without being closed (get where the object was created): https://bitbucket.org/haypo/misc/src/tip/python/res_warn.py I didn't find how to implement that using the C module. It's name is _pyio, not pyio. It is a private module. It was also written to provide a working and well tested pure Python implementation for other Python virtual machines like PyPy, IronPython and Jython. -- nosy: +haypo ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19973 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I guess we're signed up to maintain two implementations of a bunch of things for eternity, then. -- resolution: - wont fix stage: - committed/rejected status: open - closed type: - enhancement ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19973 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

STINNER Victor added the comment: We tried a pure python implementation of io once. Didn't go so well. :p It is _pyio. Note: _pyio is not 100% *pure* Python, it relies on FileIO which is implemented in C. I always found this surprising. One day I will maybe rewrite it using os.read() and os.write() :-) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19973 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19973] Deprecate pyio
Amaury Forgeot d'Arc added the comment: PyPy also has a C-translated version of the io module. It's a bit faster I think, but more importantly it has correct behavior with signals and other asynchronous errors. _pyio.py can be stopped in the middle of any function, and is not completely signal-safe. -- nosy: +amaury.forgeotdarc ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19973 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Antoine Pitrou added the comment: Then if Jython and IronPython are not using _pyio we can probably remove the file. _pyio can be useful for prototyping. Whether or not other implementations use it is quite irrelevant IMO. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19973 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue19973] Deprecate pyio
Larry Hastings added the comment: Yes, but it's a small utility. If it costs nothing to maintain _pyio then okay. But if we're spending measurable time on it but it's only a nice-to-have then we should drop it. (Full disclosure: I have no idea how much work goes into maintaining _pyio.) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19973 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
