It is not a perfect diagnosis of all error paths, but for 90% of the cases it should provide the user with the clue they need. [jc: I ended up wording slightly differently, and fixed another confusing error message I noticed while reviewing the code.] Signed-off-by: Amos Waterland Signed-off-by: Junio C Hamano --- diff --git a/update-cache.c b/update-cache.c index 63815ed65..3d1fd2be7 100644 --- a/update-cache.c +++ b/update-cache.c @@ -53,7 +53,11 @@ static int add_file_to_cache(char *path) if (allow_remove) return remove_file_from_cache(path); } - return error("open(\"%s\"): %s", path, strerror(errno)); + if (0 == status) + return error("%s: is a directory", path); + else + return error("lstat(\"%s\"): %s", path, + strerror(errno)); } namelen = strlen(path); size = cache_entry_size(namelen); @@ -393,7 +397,7 @@ int main(int argc, char **argv) continue; } if (add_file_to_cache(path)) - die("Unable to add %s to database", path); + die("Unable to add %s to database; maybe you want to use --add option?", path); } if (write_cache(newfd, active_cache, active_nr) || commit_index_file(&cache_file))
