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
Linus Torvalds	1b555932cd	Fix seriously broken "git pack-refs" Do NOT try this on a repository you care about: git pack-refs --all --prune git pack-refs because while the first "pack-refs" does the right thing, the second pack-refs will totally screw you over. This is because the second one tries to pack only tags; we should also pack what are already packed -- otherwise we would lose them.

Junio C Hamano	0f018baba6	--prune is now default for 'pack-refs' There is no reason not to, really. 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
Alexandre Julliard	ca8e2d86c4	pack-refs: Store the full name of the ref even when packing only tags. Using for_each_tag_ref() to enumerate tags is wrong since it removes the refs/tags/ prefix, we need to always use for_each_ref() and filter out non-tag references in the callback.

Junio C Hamano	b3d4204fc4	git-pack-refs --all This changes 'git-pack-refs' to pack only tags by default. Branches are meant to be updated, either by committing onto it yourself or tracking remote branches, and packed entries can become stale easily, but tags are usually "create once and live forever" and benefit more from packing.

Junio C Hamano	4431fcc4b1	Clean-up lock-ref implementation This drops "mustexist" parameter lock_ref_sha1() and lock_any_ref_forupdate() functions take. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago

Junio C Hamano	9688460152	git-pack-refs --prune "git pack-refs --prune", after successfully packing the existing refs, removes the loose ref files. It tries to protect against race by doing the usual lock_ref_sha1() which makes sure the contents of the ref has not changed since we last looked at. Also we do not bother trying to prune what was already packed, and we do not try pruning symbolic refs. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	13e4aa90ac	pack-refs: do not pack symbolic refs. Now we can tell which one is symbolic and which one is not, it is easy to do so. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	8da1977554	Tell between packed, unpacked and symbolic refs. This adds a "int *flag" parameter to resolve_ref() and makes for_each_ref() family to call callback function with an extra "int flag" parameter. They are used to give two bits of information (REF_ISSYMREF and REF_ISPACKED) about the ref. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	cb5d709ff8	Add callback data to for_each_ref() family. This is a long overdue fix to the API for for_each_ref() family of functions. It allows the callers to specify a callback data pointer, so that the caller does not have to use static variables to communicate with the callback funciton. The updated for_each_ref() family takes a function of type int (fn)(const char , const unsigned char , void ) and a void pointer as parameters, and calls the function with the name of the ref and its SHA-1 with the caller-supplied void pointer as parameters. The commit updates two callers, builtin-name-rev.c and builtin-pack-refs.c as an example. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Linus Torvalds	e1e22e37f4	Start handling references internally as a sorted in-memory list This also adds some very rudimentary support for the notion of packed refs. HOWEVER! At this point it isn't used to actually look up a ref yet, only for listing them (ie "for_each_ref()" and friends see the packed refs, but none of the other single-ref lookup routines). Note how we keep two separate lists: one for the loose refs, and one for the packed refs we read. That's so that we can easily keep the two apart, and read only one set or the other (and still always make sure that the loose refs take precedence). [ From this, it's not actually obvious why we'd keep the two separate lists, but it's important to have the packed refs on their own list later on, when I add support for looking up a single loose one. For that case, we will want to read _just_ the packed refs in case the single-ref lookup fails, yet we may end up needing the other list at some point in the future, so keeping them separated is important ] Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
