I don't think that will work at all: We only use fopen() to write thisimage, which only truncates the file, but doesn't modify mtime of the directory. Nor do we create any other (temporary) directory entries that would modify the mtime. Would it be possible to update the timestamp of preimage every time it is used (e.g., in rerere.c:merge()), and check for that? -- Hannes -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
