Confirmed the presence of this same problem in the source code of 
parsermodule.c in branches release25-maint and release26-maint.

[issue4963] mimetypes.guess_extension result changes after mimetypes.init()

2017-05-08 Thread David Hess 

David Hess added the comment:

Concur with @sivert – the result of guess_extension() is non-deterministic 
between mimetypes module initialization.

[issue4963] mimetypes.guess_extension result changes after mimetypes.init()

2017-05-08 Thread David Hess 

David Hess added the comment:

And the underlying problem causing this:

$ python -c 'import 
mimetypes;print(mimetypes.guess_all_extensions("image/jpeg"))'
['.jpeg', '.jpg', '.jpe']
$ python -c 'import 
mimetypes;print(mimetypes.guess_all_extensions("image/jpeg"))'
['.jpg', '.jpe', '.jpeg']
$ python -c 'import 
mimetypes;print(mimetypes.guess_all_extensions("image/jpeg"))'
['.jpg', '.jpeg', '.jpe']
$ python -c 'import 
mimetypes;print(mimetypes.guess_all_extensions("image/jpeg"))'
['.jpe', '.jpg', '.jpeg']
$ python -c 'import 
mimetypes;print(mimetypes.guess_all_extensions("image/jpeg"))'
['.jpeg', '.jpg', '.jpe']
$ 

If the module can't know which extension is preferred, perhaps guess_extension 
should just be deprecated and the results of guess_all_extensions sorted on 
return?

At least that would give us some determinism to work with.
