2017-06-15config: don't include config.h by defaultLibravatar Brandon Williams1-0/+1
Stop including config.h by default in cache.h. Instead only include config.h in those files which require use of the config system. Signed-off-by: Brandon Williams <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-02-20delete_ref: accept a reflog message argumentLibravatar Kyle Meyer1-1/+1
When the current branch is renamed with 'git branch -m/-M' or deleted with 'git update-ref -m<msg> -d', the event is recorded in HEAD's log with an empty message. In preparation for adding a more meaningful message to HEAD's log in these cases, update delete_ref() to take a message argument and pass it along to ref_transaction_delete(). Modify all callers to pass NULL for the new message argument; no change in behavior is intended. Note that this is relevant for HEAD's log but not for the deleted ref's log, which is currently deleted along with the ref. Even if it were not, an entry for the deletion wouldn't be present in the deleted ref's log. files_transaction_commit() writes to the log if REF_NEEDS_COMMIT or REF_LOG_ONLY are set, but lock_ref_for_update() doesn't set REF_NEEDS_COMMIT for the deleted ref because REF_DELETING is set. In contrast, the update for HEAD has REF_LOG_ONLY set by split_head_update(), resulting in the deletion being logged.

2016-09-02symbolic-ref -d: do not allow removal of HEADLibravatar Junio C Hamano1-0/+2
If you delete the symbolic-ref HEAD from a repository, Git no longer considers the repository valid, and even "git symbolic-ref HEAD refs/heads/master" would not be able to recover from that state (although "git init" can, but that is a sure sign that you are talking about a "broken" repository). In the spirit similar to afe5d3d5 ("symbolic ref: refuse non-ref targets in HEAD", 2009-01-29), forbid removal of HEAD to avoid corrupting a repository.

2015-12-21symbolic-ref: propagate error code from create_symref()Libravatar Jeff King1-1/+1
If create_symref() fails, git-symbolic-ref will still exit with code 0, and our caller has no idea that the command did nothing. This appears to have been broken since the beginning of time (e.g., it is not a regression where create_symref() stopped calling die() or something similar).

2015-01-14standardize usage info string formatLibravatar Alex Henrie1-2/+2
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>
2014-10-15refs.c: change resolve_ref_unsafe reading argument to be a flags fieldLibravatar Ronnie Sahlberg1-1/+1
resolve_ref_unsafe takes a boolean argument for reading (a nonexistent ref resolves successfully for writing but not for reading). Change this to be a flags field instead, and pass the new constant RESOLVE_REF_READING when we want this behaviour. While at it, swap two of the arguments in the function to put output arguments at the end. As a nice side effect, this ensures that we can catch callers that were unaware of the new API so they can be audited. Give the wrapper functions resolve_refdup and read_ref_full the same treatment for consistency.

2013-12-05replace {pre,suf}fixcmp() with {starts,ends}_with()Libravatar Christian Couder1-1/+1
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.

2013-10-16C: have space around && and || operatorsLibravatar Junio C Hamano1-1/+1
Correct all hits from git grep -e '\(&&\|||\)[^ ]' -e '[^ ]\(&&\|||\)' -- '*.c' i.e. && or || operators that are followed by anything but a SP, or that follow something other than a SP or a HT, so that these operators have a SP around it when necessary. We usually refrain from making this kind of a tree-wide change in order to avoid unnecessary conflicts with other "real work" patches, but in this case, the end result does not have a potentially cumbersome tree-wide impact, while this is a tree-wide cleanup. Fixes to compat/regex/regcomp.c and xdiff/xemit.c are to replace a HT immediately after && with a SP. This is based on Felipe's patch to bultin/symbolic-ref.c; I did all the finding out what other files in the whole tree need to be fixed and did the fix and also the log message while reviewing that single liner, so any screw-ups in this version are mine.

2012-10-21git symbolic-ref --delete $symrefLibravatar Johan Herland1-10/+23
Teach symbolic-ref to delete symrefs by adding the -d/--delete option to git-symbolic-ref. Both proper and dangling symrefs are deleted by this option, but other refs - or anything else that is not a symref - is not. The symref deletion is performed by first verifying that we are given a proper symref, and then invoking delete_ref() on it with the REF_NODEREF flag.

2012-02-27symbolic-ref --short: abbreviate the output unambiguouslyLibravatar Jan Krüger1-3/+8

2011-12-13Rename resolve_ref() to resolve_ref_unsafe()Libravatar Nguyễn Thái Ngọc Duy1-1/+1
resolve_ref() may return a pointer to a shared buffer and can be overwritten by the next resolve_ref() calls. Callers need to pay attention, not to keep the pointer when the next call happens. Rename with "_unsafe" suffix to warn developers (or reviewers) before introducing new call sites.

2010-02-22Move 'builtin-*' into a 'builtin/' subdirectoryLibravatar Linus Torvalds1-0/+57
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>
