From c51c0da2225d65ec1984d40bacbc3f43a0bfa178 Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Wed, 18 Aug 2010 20:48:03 -0500 Subject: [PATCH] tests: exercise "git apply" with weird filenames Check that "git apply" can cope with strange filenames, particularly filenames with spaces. Not all platforms have a sane enough diff -u and expand to reliably create the such patches and maybe future versions of GNU diff will handle funny characters differently, so this uses pre-generated patches. The script used to generate them is in t/t4135/make-patches. Filenames with tabs are not usable on NTFS; use something like the FUNNYNAMES prerequisite from v1.3.0-rc1~67 (2006-03-03) to skip the relevant tests when appropriate. The detection is not shared in test-lib.sh to avoid wasting time while running other test scripts. Backslash is the path separator on Windows, so do not used it in file names there (v1.6.3-rc0~93^2~6, 2009-03-13). Finally, filenames starting with a quotation mark do not behave well in msys (see v1.7.0-rc0~94^2, t4030, t4031: work around bogus MSYS bash path conversion, 2010-01-01), so skip those tests on Windows, too.
