@eryksun, I wasn't able to use this for _path_is*(), since I can't prevent a UnicodeDecodeError from being raised (like for b'\xff').
See https://github.com/python/cpython/actions/runs/8862420350/job/24335361259#step:5:709

I was able to speed up os.path.splitroot() & os.path.normpath() though.

I think you'll be particularly pleased with this addition (I don't know why we didn't do this earlier):

cpython/Modules/posixmodule.c

Lines 5564 to 5569 in 19209c6

    
           if (!norm_len) { 
        
               result = PyUnicode_FromOrdinal('.'); 
        
           } 
        
           else { 
        
               result = PyUnicode_FromWideChar(norm_path, norm_len); 
        
           }

I wasn't able to use this for _path_is*(), since I can't prevent a UnicodeDecodeError from being raised (like for b'\xff').

The converter could set a flag in the path_t record to indicate that conversion failed with a ValueError, and another to indicate that the path has embedded null characters. There could be a single conversion option to repress raising ValueError that applies to both cases.

could we try to get this in 3.13? We only have 4 days left.

This change shouldn't affect anything compatibility-wise, and if so that needs to be addressed. It's support code for CPython. I think it could be added to beta 2 this month if it misses beta 1.

The converter could set a flag in the path_t record to indicate that conversion failed with a ValueError, and another to indicate that the path has embedded null characters. There could be a single conversion option to repress raising ValueError that applies to both cases.

I added a suppress option, which tells argument clinic you would like to handle errors manually, otherwise path_converter() will get too complex.

@barneygale, are the changes to the docstring of os.path.splitroot() fine? There's no great way to make the docstring of the C implementation different on Windows and Linux. You don't need to review the rest of this pull request.

nineteendo · 2024-05-22T08:30:39Z

@eryksun, could you add backport labels? I also want to backport it to 3.12 (with the necessary changes) to use for ntpath.abspath().

nineteendo · 2024-05-22T09:11:21Z

Thanks, do you think this looks ready?

zooba

Love it! path_t might be my favourite thing about argument clinic, so great to see it getting even better.

One question and one comment below.

Sorry, @nineteendo and @zooba, I could not cleanly backport this to 3.12 due to a conflict.
