* show-ref: fix --exclude-existingJunio C Hamano2006-12-18
| | | | | | | | | | Do not falsely document --filter-invalid which does not even exist. Also make sure the line is long enough to have ^{} suffix before checking for it. Pointed out by Dscho. Signed-off-by: Junio C Hamano <junkio@cox.net>
* show-ref: fix --verify --hash=lengthJunio C Hamano2006-12-17
| | | | | | | | | | | An earlier optimization for --verify broke a lot of stuff because it did not take interaction with other flags into account. This also fixes an unrelated argument parsing error; --hash=8 should mean the same as "--hash --abbrev=8". Signed-off-by: Junio C Hamano <junkio@cox.net>

* avoid accessing _all_ loose refs in git-show-ref --verifyJunio C Hamano2006-12-17
| | | | | | | | If you want to verify a ref, it is overkill to first read all loose refs into a linked list, and then check if the desired ref is there. Signed-off-by: Junio C Hamano <junkio@cox.net> Acked-by: Johannes Schindelin <Johannes.Schindelin@gmx.de>
* git-fetch: Avoid reading packed refs over and over againJunio C Hamano2006-12-17
| | | | | | | | | | | | When checking which tags to fetch, the old code used to call git-show-ref --verify for each remote tag. Since reading even packed refs is not a cheap operation when there are a lot of local refs, the code became quite slow. This fixes it by teaching git-show-ref to filter out existing refs using a new mode of operation of git-show-ref. Signed-off-by: Junio C Hamano <junkio@cox.net>
* Store peeled refs in packed-refs (take 2).Junio C Hamano2006-11-21
| | | | | | | | | | | | | | | | | This fixes the previous implementation which failed to optimize repositories with tons of lightweight tags. The updated packed-refs format begins with "# packed-refs with:" line that lists the kind of extended data the file records. Currently, there is only one such extension defined, "peeled". This stores the "peeled tag" on a line that immediately follows a line for a tag object itself in the format "^<sha-1>". The header line itself and any extended data are ignored by older implementation, so packed-refs file generated with this version can still be used by older git. packed-refs made by older git can of course be used with this version.

* Add "git show-ref" builtin commandLinus Torvalds2006-09-16
It's kind of like "git peek-remote", but works only locally (and thus avoids the whole overhead of git_connect()) and has some extra verification features. For example, it allows you to filter the results, and to choose whether you want the tag dereferencing or not. You can also use it to just test whether a particular ref exists. For example: git show-ref master will show all references called "master", whether tags or heads or anything else, and regardless of how deep in the reference naming hierarchy they are (so it would show "refs/heads/master" but also "refs/remote/other-repo/master"). When using the "--verify" flag, the command requires an exact ref path: git show-ref --verify refs/heads/master will only match the exact branch called "master". If nothing matches, show-ref will return an error code of 1, and in the case of verification, it will show an error message. For scripting, you can ask it to be quiet with the "--quiet" flag, which allows you to do things like git-show-ref --quiet --verify -- "refs/heads/$headname" || echo "$headname is not a valid branch" to check whether a particular branch exists or not (notice how we don't actually want to show any results, and we want to use the full refname for it in order to not trigger the problem with ambiguous partial matches). To show only tags, or only proper branch heads, use "--tags" and/or "--heads" respectively (using both means that it shows tags _and_ heads, but not other random references under the refs/ subdirectory). To do automatic tag object dereferencing, use the "-d" or "--dereference" flag, so you can do git show-ref --tags --dereference to get a listing of all tags together with what they dereference.
