Subject: bpo-46316: optimize `pathlib.Path.iterdir()` (GH-30501)
X-Git-Tag: v3.11.0a5~195
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a1c88414926610a3527398a478c3e63c531dc742;p=thirdparty%2FPython%2Fcpython.git

bpo-46316: optimize `pathlib.Path.iterdir()` (GH-30501)

`os.listdir()` doesn't return entries for `.` or `..`, so we don't need to
check for them here.
