From bb233d690a9782e1570dc93ead2bf04aaca7cfe4 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Thu, 21 Apr 2005 10:55:18 -0700 Subject: Add support for a "GIT_INDEX_FILE" environment variable. We use that to specify alternative index files, which can be useful if you want to (for example) generate a temporary index file to do some specific operation that you don't want to mess with your main one with. It defaults to the regular ".git/index" if it hasn't been specified. --- update-cache.c | 19 +++++++++++-------- 1 file changed, 11 insertions(+), 8 deletions(-) (limited to 'update-cache.c') diff --git a/update-cache.c b/update-cache.c index 8ec69e22b4..4353b80890 100644 --- a/update-cache.c +++ b/update-cache.c @@ -274,25 +274,29 @@ static int add_cacheinfo(char *arg1, char *arg2, char *arg3) return add_cache_entry(ce, allow_add); } -static int remove_lock = 0; +static const char *lockfile_name = NULL; static void remove_lock_file(void) { - if (remove_lock) - unlink(".git/index.lock"); + if (lockfile_name) + unlink(lockfile_name); } int main(int argc, char **argv) { int i, newfd, entries; int allow_options = 1; + static char lockfile[MAXPATHLEN+1]; + const char *indexfile = get_index_file(); - newfd = open(".git/index.lock", O_RDWR | O_CREAT | O_EXCL, 0600); + snprintf(lockfile, sizeof(lockfile), "%s.lock", indexfile); + + newfd = open(lockfile, O_RDWR | O_CREAT | O_EXCL, 0600); if (newfd < 0) die("unable to create new cachefile"); atexit(remove_lock_file); - remove_lock = 1; + lockfile_name = lockfile; entries = read_cache(); if (entries < 0) @@ -333,10 +337,9 @@ int main(int argc, char **argv) if (add_file_to_cache(path)) die("Unable to add %s to database", path); } - if (write_cache(newfd, active_cache, active_nr) || - rename(".git/index.lock", ".git/index")) + if (write_cache(newfd, active_cache, active_nr) || rename(lockfile, indexfile)) die("Unable to write new cachefile"); - remove_lock = 0; + lockfile_name = NULL; return 0; } -- cgit v1.2.3
