This makes git-peek-remote able to basically do everything that git-ls-remote does (but obviously just for the native protocol, so no http[s]: or rsync: support). The default behaviour is the same, but you can now give a mixture of "--refs", "--tags" and "--heads" flags, where "--refs" forces git-peek-remote to only show real refs (ie none of the fakey tag lookups, but also not the special pseudo-refs like HEAD and MERGE_HEAD). The "--tags" and "--heads" flags respectively limit the output to just regular tags and heads, of course. You can still also ask to limit them by name too. You can combine the flags, so git peek-remote --refs --tags . will show all local _true_ tags, without the generated tag lookups (compare the output without the "--refs" flag). And "--tags --heads" will show both tags and heads, but will avoid (for example) any special refs outside of the standard locations. I'm also planning on adding a "--ignore-local" flag that allows us to ask it to ignore any refs that we already have in the local tree, but that's an independent thing. All this is obviously gearing up to making "git fetch" cheaper. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
