Nguyễn Thái Ngọc Duy	8cad4744ee	Rename resolve_ref() to resolve_ref_unsafe() 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. This patch is generated using the following command git grep -l 'resolve_ref(' -- '*.[ch]'\|xargs sed -i 's/resolve_ref(/resolve_ref_unsafe(/g' Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	13 years ago

Linus Torvalds	81b50f3ce4	Move 'builtin-' into a 'builtin/' subdirectory 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>	15 years ago
Stephen Boyd	3778292017	parse-opts: prepare for OPT_FILENAME To give OPT_FILENAME the prefix, we pass the prefix to parse_options() which passes the prefix to parse_options_start() which sets the prefix member of parse_opts_ctx accordingly. If there isn't a prefix in the calling context, passing NULL will suffice. Signed-off-by: Stephen Boyd <bebarino@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	16 years ago
Jeff King	e9cc02f0e4	symbolic-ref: allow refs/<whatever> in HEAD Commit `afe5d3d5` introduced a safety valve to symbolic-ref to disallow installing an invalid HEAD. It was accompanied by `b229d18a`, which changed validate_headref to require that HEAD contain a pointer to refs/heads/ instead of just refs/. Therefore, the safety valve also checked for refs/heads/. As it turns out, topgit is using refs/top-bases/ in HEAD, leading us to re-loosen (at least temporarily) the validate_headref check made in `b229d18a`. This patch does the corresponding loosening for the symbolic-ref safety valve, so that the two are in agreement once more.

Jeff King	afe5d3d516	symbolic ref: refuse non-ref targets in HEAD When calling "git symbolic-ref" it is easy to forget that the target must be a fully qualified ref. E.g., you might accidentally do: $ git symbolic-ref HEAD master Unfortunately, this is very difficult to recover from, because the bogus contents of HEAD make git believe we are no longer in a git repository (as is_git_dir explicitly checks for "^refs/heads/" in the HEAD target). So immediately trying to fix the situation doesn't work: $ git symbolic-ref HEAD refs/heads/master fatal: Not a git repository and one is left editing the .git/HEAD file manually. Furthermore, one might be tempted to use symbolic-ref to set up a detached HEAD: $ git symbolic-ref HEAD `git rev-parse HEAD` which sets up an even more bogus HEAD: $ cat .git/HEAD ref: 1a9ace4f2ad4176148e61b5a85cd63d5604aac6d This patch introduces a small safety valve to prevent the specific case of anything not starting with refs/heads/ to go into HEAD. The scope of the safety valve is intentionally very limited, to make sure that we are not preventing any behavior that would otherwise be valid (like pointing a different symref than HEAD outside of refs/heads/).

Stephan Beyer	1b1dd23f2d	Make usage strings dash-less When you misuse a git command, you are shown the usage string. But this is currently shown in the dashed form. So if you just copy what you see, it will not work, when the dashed form is no longer supported. This patch makes git commands show the dash-less version. For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh generates a dash-less usage string now.

Johannes Schindelin	ef90d6d420	Provide git_config with a callback-data parameter git_config() only had a function parameter, but no callback data parameter. This assumes that all callback functions only modify global variables. With this patch, every callback gets a void * parameter, and it is hoped that this will help the libification effort.

Junio C Hamano	283884422f	symbolic-ref, update-ref: do not refuse reflog message with LF Earlier these tools refused to create a reflog entry when the message given by the calling Porcelain had a LF in it, partially to keep the file format integrity of reflog file, which is one-entry-per-line. These tools should not be dictating such a policy. Instead, let the codepath to write out the reflog entry worry about the format integrity and allow messages with LF in them.

Junio C Hamano	a0f4280f9e	Fix git-fetch while on detached HEAD not to give needlessly alarming errors When we are on a detached HEAD, there is no current branch. There is no reason to leak the error messages to the end user since this is a situation we expect to see. This adds -q option to git-symbolic-ref to exit without issuing an error message if the given name is not a symbolic ref. By the way, with or without this patch, there currently is no good way to tell failure modes between "git symbolic-ref HAED" and "git symbolic-ref HEAD". Both says "is not a symbolic ref". We may want to do something about it. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 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>	18 years ago
Junio C Hamano	cc4c4f0ce2	symbolit-ref: fix resolve_ref conversion. An earlier conversion accidentally hardcoded "HEAD" to be passed to resolve_ref(), thereby causing git-symbolic-ref command to always report where the HEAD points at, ignoring the command line parameter.

Linus Torvalds	ed378ec7e8	Make ref resolution saner The old code used to totally mix up the notion of a ref-name and the path that that ref was associated with. That was not only horribly ugly (a number of users got the path, and then wanted to try to turn it back into a ref-name again), but it fundamnetally doesn't work at all once we do any setup where a ref doesn't have a 1:1 relationship with a particular pathname. This fixes things up so that we use the ref-name throughout, and only turn it into a pathname once we actually look it up in the filesystem. That makes a lot of things much clearer and more straightforward. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Shawn Pearce	9befac470b	Replace uses of strdup with xstrdup. Like xmalloc and xrealloc xstrdup dies with a useful message if the native strdup() implementation returns NULL rather than a valid pointer. I just tried to use xstrdup in new code and found it to be missing. However I expected it to be present as xmalloc and xrealloc are already commonly used throughout the code. [jc: removed the part that deals with last_XXX, which I am finding more and more dubious these days.] Signed-off-by: Shawn O.

Junio C Hamano	8098a178b2	Add git-symbolic-ref This adds the counterpart of git-update-ref that lets you read and create "symbolic refs". By default it uses a symbolic link to represent ".git/HEAD -> refs/heads/master", but it can be compiled to use the textfile symbolic ref. The places that did 'readlink .git/HEAD' and 'ln -s refs/heads/blah .git/HEAD' have been converted to use new git-symbolic-ref command, so that they can deal with either implementation.
