2015-05-25each_ref_fn: change to take an object_id parameterLibravatar Michael Haggerty1-3/+8
Change typedef each_ref_fn to take a "const struct object_id *oid" parameter instead of "const unsigned char *sha1". To aid this transition, implement an adapter that can be used to wrap old-style functions matching the old typedef, which is now called "each_ref_sha1_fn"), and make such functions callable via the new interface. This requires the old function and its cb_data to be wrapped in a "struct each_ref_fn_sha1_adapter", and that object to be used as the cb_data for an adapter function, each_ref_fn_adapter(). This is an enormous diff, but most of it consists of simple, mechanical changes to the sites that call any of the "for_each_ref" family of functions. Subsequent to this change, the call sites can be rewritten one by one to use the new interface.

2015-01-14standardize usage info string formatLibravatar Alex Henrie1-1/+1
This patch puts the usage info strings that were not already in docopt- like format into docopt-like format, which will be a litle easier for end users and a lot easier for translators. Changes include: - Placing angle brackets around fill-in-the-blank parameters - Putting dashes in multiword parameter names - Adding spaces to [-f|--foobar] to make [-f | --foobar] - Replacing <foobar>* with [<foobar>...] Signed-off-by: Alex Henrie <alexhenrie24@gmail.com> Reviewed-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-12-05replace {pre,suf}fixcmp() with {starts,ends}_with()Libravatar Christian Couder1-3/+3
Leaving only the function definitions and declarations so that any new topic in flight can still make use of the old functions, replace existing uses of the prefixcmp() and suffixcmp() with new API functions. The change can be recreated by mechanically applying this: $ git grep -l -e prefixcmp -e suffixcmp -- \*.c | grep -v strbuf\\.c | xargs perl -pi -e ' s|!prefixcmp\(|starts_with\(|g; s|prefixcmp\(|!starts_with\(|g; s|!suffixcmp\(|ends_with\(|g; s|suffixcmp\(|!ends_with\(|g; ' on the result of preparatory changes in this series.

2013-08-05Replace deprecated OPT_BOOLEAN by OPT_BOOLLibravatar Stefan Beller1-5/+5
This task emerged from b04ba2bb (parse-options: deprecate OPT_BOOLEAN, 2011-09-27). All occurrences of the respective variables have been reviewed and none of them relied on the counting up mechanism, but all of them were using the variable as a true boolean. This patch does not change semantics of any command intentionally. Signed-off-by: Stefan Beller <stefanbeller@googlemail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2013-08-05Remove deprecated OPTION_BOOLEAN for parsing argumentsLibravatar Stefan Beller1-3/+2
As of b04ba2bb4 OPTION_BOOLEAN was deprecated. This commit removes all occurrences of OPTION_BOOLEAN. In b04ba2bb4 Junio suggested to replace it with either OPTION_SET_INT or OPTION_COUNTUP instead. However a pattern, which occurred often with the OPTION_BOOLEAN was a hidden boolean parameter. So I defined OPT_HIDDEN_BOOL as an additional possible parse option in parse-options.h to make life easy. The OPT_HIDDEN_BOOL was used in checkout, clone, commit, show-ref. The only exception, where there was need to fiddle with OPTION_SET_INT was log and notes. However in these two files there is also a pattern, so we could think of introducing OPT_NONEG_BOOL.

2013-07-22Merge branch 'db/show-ref-head'Libravatar Junio C Hamano1-2/+6
The "--head" option to "git show-ref" was only to add "HEAD" to the list of candidate refs to be filtered by the usual rules (e.g. "--heads" that only show refs under refs/heads). Change the meaning of the option to always show "HEAD" regardless of what filtering will be applied to any other ref (this is a backward incompatible change, so I may need to add an entry to the Release Notes). * db/show-ref-head: show-ref: make --head always show the HEAD ref
2013-07-17show-ref: make --head always show the HEAD refLibravatar Doug Bell1-2/+6
The docs seem to say that doing git show-ref --head --tags would show both the HEAD ref and all the tag refs. However, doing both --head and either of --tags or --heads would filter out the HEAD ref. Also update the documentation to describe the new behavior and add tests for the show-ref command. [jc: Doug did proofread the tests, but it was done by me and bugs in it are mine].

2013-06-02exclude_existing(): set existing_refs.strdup_stringsLibravatar Michael Haggerty1-1/+1
The each_ref_fn add_existing() adds refnames to the existing_refs list. But the lifetimes of these refnames is not guaranteed by the refs API, so configure the string_list to make copies as it adds them.

2012-10-25Merge branch 'jk/peel-ref'Libravatar Jeff King1-20/+3
Speeds up "git upload-pack" (what is invoked by "git fetch" on the other side of the connection) by reducing the cost to advertise the branches and tags that are available in the repository. * jk/peel-ref: upload-pack: use peel_ref for ref advertisements peel_ref: check object type before loading peel_ref: do not return a null sha1 peel_ref: use faster deref_tag_noverify
2012-10-04peel_ref: do not return a null sha1Libravatar Jeff King1-20/+3
The idea of the peel_ref function is to dereference tag objects recursively until we hit a non-tag, and return the sha1. Conceptually, it should return 0 if it is successful (and fill in the sha1), or -1 if there was nothing to peel. However, the current behavior is much more confusing. For a regular loose ref, the behavior is as described above. But there is an optimization to reuse the peeled-ref value for a ref that came from a packed-refs file. If we have such a ref, we return its peeled value, even if that peeled value is null (indicating that we know the ref definitely does _not_ peel). It might seem like such information is useful to the caller, who would then know not to bother loading and trying to peel the object. Except that they should not bother loading and trying to peel the object _anyway_, because that fallback is already handled by peel_ref. In other words, the whole point of calling this function is that it handles those details internally, and you either get a sha1, or you know that it is not peel-able. This patch catches the null sha1 case internally and converts it into a -1 return value (i.e., there is nothing to peel). This simplifies callers, which do not need to bother checking themselves. Two callers are worth noting: - in pack-objects, a comment indicates that there is a difference between non-peelable tags and unannotated tags. But that is not the case (before or after this patch). Whether you get a null sha1 has to do with internal details of how peel_ref operated. - in show-ref, if peel_ref returns a failure, the caller tries to decide whether to try peeling manually based on whether the REF_ISPACKED flag is set. But this doesn't make any sense. If the flag is set, that does not necessarily mean the ref came from a packed-refs file with the "peeled" extension. But it doesn't matter, because even if it didn't, there's no point in trying to peel it ourselves, as peel_ref would already have done so. In other words, the fallback peeling is guaranteed to fail.

2011-11-13Convert many resolve_ref() calls to read_ref*() and ref_exists()Libravatar Nguyễn Thái Ngọc Duy1-1/+1
resolve_ref() may return a pointer to a static buffer, which is not safe for long-term use because if another resolve_ref() call happens, the buffer may be changed. Many call sites though do not care about this buffer. They simply check if the return value is NULL or not. Convert all these call sites to new wrappers to reduce resolve_ref() calls from 57 to 34. If we change resolve_ref() prototype later on to avoid passing static buffer out, this helps reduce changes.

2011-10-05Change check_ref_format() to take a flags argumentLibravatar Michael Haggerty1-1/+1
Change check_ref_format() to take a flags argument that indicates what is acceptable in the reference name (analogous to "git check-ref-format"'s "--allow-onelevel" and "--refspec-pattern"). This is more convenient for callers and also fixes a failure in the test suite (and likely elsewhere in the code) by enabling "onelevel" and "refspec-pattern" to be allowed independently of each other. Also rename check_ref_format() to check_refname_format() to make it obvious that it deals with refnames rather than references themselves.

2010-02-22Move 'builtin-*' into a 'builtin/' subdirectoryLibravatar Linus Torvalds1-0/+249
This shrinks the top-level directory a bit, and makes it much more pleasant to use auto-completion on the thing. Instead of [torvalds@nehalem git]$ em buil<tab> Display all 180 possibilities? (y or n) [torvalds@nehalem git]$ em builtin-sh builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o [torvalds@nehalem git]$ em builtin-shor<tab> builtin-shortlog.c builtin-shortlog.o [torvalds@nehalem git]$ em builtin-shortlog.c you get [torvalds@nehalem git]$ em buil<tab> [type] builtin/ builtin.h [torvalds@nehalem git]$ em builtin [auto-completes to] [torvalds@nehalem git]$ em builtin/sh<tab> [type] shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o [torvalds@nehalem git]$ em builtin/sho [auto-completes to] [torvalds@nehalem git]$ em builtin/shor<tab> [type] shortlog.c shortlog.o [torvalds@nehalem git]$ em builtin/shortlog.c which doesn't seem all that different, but not having that annoying break in "Display all 180 possibilities?" is quite a relief. NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
