Subject: t3070: skip ls-files tests with backslash patterns on Windows
X-Git-Tag: v2.55.0-rc0~2^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8c84e6802c0e23503bfe655dadcdc4a15de7373a;p=thirdparty%2Fgit.git

t3070: skip ls-files tests with backslash patterns on Windows

On Windows (MINGW), backslashes in pathspecs are silently converted to
forward slashes (directory separators), which changes the glob semantics.
This causes 36 test failures in t3070-wildmatch when the "via ls-files"
variants test patterns containing backslash escapes (e.g. '\[ab]',
'[\-_]', '[A-\\]').

The wildmatch function itself handles these patterns correctly — only the
ls-files code path fails because pathspec parsing converts the
backslashes before they reach the glob matcher.

Skip these ls-files tests on platforms where BSLASHPSPEC is not set,
which is the existing prereq that captures exactly this semantic:
"backslashes in pathspec are not directory separators."
