Ah, I thought that was what you wanted (to find specific files, not a pattern). I think `ls-tree` doesn't understand our normal pathspecs, for historical reasons. > Also, BUILD files are scattered throughout the tree, so the entire tree > would still need to be traversed.

I.e., it can limit the traversal for a prefix-match, but it cannot do so for an arbitrary filename. It has to open every tree. So the extra expense is really just the I/O over the pipe. That's not optimal, but it is a constant factor slowdown from what git would do internally. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
