I know I'm atypical, but I have quite a lot of multithreaded stuff, including command line code. So while it'd be ok to avoid this context manager for my own code, I fear library modules, either stdlib or pypi, quietly using this in their code, making them unuseable in the general case. Unrepairably unuseable, for the user.
Library code shouldn't be changing the working directory, context manager or not. That belongs to the application.
Entirely agree.
I'm concerned that convenient stackable chdir is a bug magnet, and would creep into library code. Maybe not in the stdlib, but there's no point writing such a context manager if it isn't goingg to be used, and therefore it could get used in library code. Imagine when a popular pypi module starts using it internally and breaks a multithreaded app previously relying on it?
I know where I'd file a bug. :-) "Bug magnet" is an extremely subjective pejorative term. When the *better* way to do things (os.workdir()) is harder than the *easy* way to do (os.chdir()), which is the real bug magnet? -- --Guido van Rossum (python.org/~guido) *Pronouns: he/him **(why is my pronoun here?)* <http://feministing.com/2015/02/03/how-using-they-as-a-singular-pronoun-can-c...>
