Subject: [3.12] gh-135034: Remove test_realpath_permission (GH-135093)
X-Git-Tag: v3.12.11~1
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=28463dba112af719df1e8b0391c46787ad756dd9;p=thirdparty%2FPython%2Fcpython.git

[3.12] gh-135034: Remove test_realpath_permission (GH-135093)

The test was added in gh-110298, with a fix that was never backported
to 3.12 and below.
It was most likely skipped in the GHA run.
