From a31c6d022e2435a514fcc8ca57f9995c4376a986 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Tue, 3 May 2005 15:16:18 -0700 Subject: [PATCH] sha1_file: make the new sha1 object writing be coda-friendly. Coda doesn't like cross-directory hardlinks. So try to fall back on a plain rename instead. --- sha1_file.c | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) diff --git a/sha1_file.c b/sha1_file.c index 8f577985a..e6ce455ae 100644 --- a/sha1_file.c +++ b/sha1_file.c @@ -353,8 +353,21 @@ int write_sha1_file(char *buf, unsigned long len, const char *type, unsigned cha close(fd); ret = link(tmpfile, filename); - if (ret < 0) + if (ret < 0) { ret = errno; + + /* + * Coda hack - coda doesn't like cross-directory links, + * so we fall back to a rename, which will mean that it + * won't be able to check collisions, but that's not a + * big deal. + * + * When this succeeds, we just return 0.
