I have no idea; at least to me, "--exclude" option to "git apply" was invented to name individual paths, not patterns, and I wouldn't be surprised if glob working were merely by accident not by design. > Another nit: if a patch contains only changes to files inside arch/mips > then git-apply will create an "empty commit" (one with no diff).

"git am" may pass the "--exclude/--include" options to "git apply" but I wouldn't be surprised if that support was added without thinking. Perhaps the reason why you discovered that it needed a lot more thinking to properly integrate these options to "git am" only now is because hardly anybody uses it ;-). Not just passing these options, the code in "git am" to react to the result of patch application to avoid the issue you observed when these options are passed need to be adjusted by changes that started passing them, but I do not think they did, cf. 77e9e496 (am: pass exclude down to apply, 2011-08-03). > One more thing: "regular" diff -q returns 0 when the files are identical, > and 1 when they differ. It seems git diff -s does not have that behavior. > Is that by design? "diff -s" may be accepted but it is an idiotic thing for a user to say. The "-s" option is to squelch output from "log" and friends, and it is exposed to "diff" only because these two families of commands share the command line parser. -- 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
