From c374b04bee1d4bfd3f742fbb3a55ea57209a1cf6 Mon Sep 17 00:00:00 2001 From: Joshua Jensen Date: Mon, 16 Aug 2010 21:38:10 +0200 Subject: [PATCH] Case insensitivity support for .gitignore via core.ignorecase This is especially beneficial when using Windows and Perforce and the git-p4 bridge. Internally, Perforce preserves a given file's full path including its case at the time it was added to the Perforce repository. When syncing a file down via Perforce, missing directories are created, if necessary, using the case as stored with the filename. Unfortunately, two files in the same directory can have differing cases for their respective paths, such as /diRa/file1.c and /DirA/file2.c. Depending on sync order, DirA/ may get created instead of diRa/. It is possible to handle directory names in a case insensitive manner without this patch, but it is highly inconvenient, requiring each character to be specified like so: [Bb][Uu][Ii][Ll][Dd]. With this patch, the gitignore exclusions honor the core.ignorecase=true configuration setting and make the process less error prone. The above is specified like so: Build Signed-off-by: Joshua Jensen Signed-off-by: Johannes Sixt Signed-off-by: Junio C Hamano --- dir.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/dir.c b/dir.c index 4d001fd632..be21c201ab 100644 --- a/dir.c +++ b/dir.c @@ -390,14 +390,14 @@ int excluded_from_list(const char *pathname, if (x->flags & EXC_FLAG_NODIR) { /* match basename */ if (x->flags & EXC_FLAG_NOWILDCARD) { - if (!strcmp(exclude, basename)) + if (!strcmp_icase(exclude, basename)) return to_exclude; } else if (x->flags & EXC_FLAG_ENDSWITH) { if (x->patternlen - 1 <= pathlen && - !strcmp(exclude + 1, pathname + pathlen - x->patternlen + 1)) + !strcmp_icase(exclude + 1, pathname + pathlen - x->patternlen + 1)) return to_exclude; } else { - if (fnmatch(exclude, basename, 0) == 0) + if (fnmatch_icase(exclude, basename, 0) == 0) return to_exclude; } } @@ -412,14 +412,14 @@ int excluded_from_list(const char *pathname, if (pathlen < baselen || (baselen && pathname[baselen-1] != '/') || - strncmp(pathname, x->base, baselen)) + strncmp_icase(pathname, x->base, baselen)) continue; if (x->flags & EXC_FLAG_NOWILDCARD) { - if (!strcmp(exclude, pathname + baselen)) + if (!strcmp_icase(exclude, pathname + baselen)) return to_exclude; } else { - if (fnmatch(exclude, pathname+baselen, + if (fnmatch_icase(exclude, pathname+baselen, FNM_PATHNAME) == 0) return to_exclude; }
