Junio C Hamano	cc44c7655f	Mechanical conversion to use prefixcmp() This mechanically converts strncmp() to use prefixcmp(), but only when the parameters match specific patterns, so that they can be verified easily. Leftover from this will be fixed in a separate step, including idiotic conversions like if (!strncmp("foo", arg, 3)) => if (!(-prefixcmp(arg, "foo"))) This was done by using this script in px.perl #!/usr/bin/perl -i.bak -p if (/strncmp$([^,]+), "([^\\"])", (\d+)$/ && (length($2) == $3)) { s\|strncmp$([^,]+), "([^\\"])", (\d+)$\|prefixcmp($1, "$2")\|; } if (/strncmp$"([^\\"])", ([^,]+), (\d+)$/ && (length($1) == $3)) { s\|strncmp$"([^\\"])", ([^,]+), (\d+)$\|(-prefixcmp($2, "$1"))\|; } and running: $ git grep -l strncmp -- '*.c' \| xargs perl px.perl Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Junio C Hamano	d8285af481	show-ref: fix --exclude-existing 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>	18 years ago
Junio C Hamano	64fe031a7a	show-ref: fix --verify --hash=length 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>	18 years ago

Junio C Hamano	26cdd1e7c7	avoid accessing _all_ loose refs in git-show-ref --verify 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.

Junio C Hamano	ed9f7c954c	git-fetch: Avoid reading packed refs over and over again 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>	18 years ago
Junio C Hamano	f4204ab9f6	Store peeled refs in packed-refs (take 2). 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.

Junio C Hamano	cf0adba788	Store peeled refs in packed-refs file. This would speed up "show-ref -d" in a repository with mostly packed tags. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago

Linus Torvalds	358ddb62cf	Add "git show-ref" builtin command 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.
