[issue27796] Expose DirEntry constructor
New submission from Brendan Moloney: As per a discussion on python-ideas [1], the consensus is that we should allow users to create a DirEntry object themselves. This would just take a path and call stat on it and cache the result of that stat call. Nick Coghlan mentioned possibly allowing a pre-existing stat result to optionally be passed into the constructor [2].

[issue27038] Make os.DirEntry exist
Brendan Moloney added the comment: The functions were all written around DirEntry objects since that is what they will be processing 99% of the time and I want to do that as efficiently as possible. Converting a DirEntry object into a str representation doesn't help me with my use case at all. I want to be able to do it the other way around: str -> DirEntry -- ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27038> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue27038] Make os.DirEntry exist
Brendan Moloney added the comment: The pathlib Path class is different enough from the DirEntry class that it doesn't really help my goal of allowing a function to work with either a DirEntry or a plain (str) path. These functions are going to be working with DirEntry objects generated by scandir 99% of the time so that we can leverage the improved performance, but I want to allow users to pass in plain paths as well. If the stdlib doesn't allow me to create my own DirEntry object from a plain path I will probably end up creating some sort of FakeDirEntry class that mimics a DirEntry, and that seems a bit silly and not a great use of time and effort. If the constructor currently "requires low-level data coming from readdir() or FindFirstFile()" then why not a class method that just takes a path and calls stat on it? You could document the fact that it calls stat and that it doesn't have any of the performance benefits of using scandir.

[issue27038] Make os.DirEntry exist
Brendan Moloney added the comment: It would be nice if there was a supported way to create a DirEntry object from a path. If you don't want to document the constructor perhaps expose some helper function or class method (i.e. from_path)? -- nosy: +moloney ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27038> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21987] TarFile.getmember on directory requires trailing slash iff over 100 chars
New submission from Brendan Moloney: If a directory path is under 100 char you have to omit the trailing slash from the name passed to 'getmember'. If it is over 100 you have to include the trailing slash. As a work around I can use the private '_getmember' with 'normalize=True'. I tested on 2.7.2 and searched the release notes looking for a related fix since then. I couldn't find anything there, or here in the issue tracker. -- components: Library (Lib) messages: 223167 nosy: moloney priority: normal severity: normal status: open title: TarFile.getmember on directory requires trailing slash iff over 100 chars type: behavior versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21987 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
