Description Brett Kerwin 2026-02-01 22:38:08 UTC 
Description of problem:
Running git-latexdiff from the base directory of a git repository fails.

Version-Release number of selected component (if applicable):
texlive-git-latexdiff-svn54732-94.fc43.x86_64

How reproducible:
always

Steps to Reproduce:
Just run a git-latexdiff of two revisions of a LaTeX file in a git repository.

Actual results:
fatal: Can't cd back to repository root

Expected results:
Display the diff file.

Additional info:
The problem comes from /usr/bin/git-latexdiff, line 596, which is

cd "$(git rev-parse --show-cdup)" || die "Can't cd back to repository root"

and indeed this line is problematic: when "git rev-parse --show-cdup" returns nothing, it executes 'cd ""', but executing cd *with* an argument which is an *empty* string must be avoided: according to the POSIX standard, the results are unspecified (see https://pubs.opengroup.org/onlinepubs/9699919799/utilities/cd.html section OPERANDS).
Comment 1 Brett Kerwin 2026-02-01 22:43:19 UTC 
I am just discovering that this has already been fixed in the latest version upstream (since v1.7.0), so just updated the version in Fedora should solve the problem.
