Johannes Schindelin	303958dc42	create_symref: if symlink fails, fall back to writing a "symbolic ref" There are filesystems out there which do not understand symlinks, even if the OS is perfectly capable of writing them. So, do not fail right away, but try to write a symbolic ref first. If that fails, you can die().

Junio C Hamano	03feddd6e8	git-check-ref-format: reject funny ref names. Update check_ref_format() function to reject ref names that: * has a path component that begins with a ".", or * has a double dots "..", or * has ASCII control character, "~", "^", ":" or SP, anywhere, or * ends with a "/". Use it in 'git-checkout -b', 'git-branch', and 'git-tag' to make sure that newly created refs are well-formed. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Linus Torvalds	4546738b58	Unlocalized isspace and friends Do our own ctype.h, just to get the sane semantics: we want locale-independence, _and_ we want the right signed behaviour. Plus we only use a very small subset of ctype.h anyway (isspace, isalpha, isdigit and isalnum). Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Jonas Fonseca	85912b0673	[PATCH] Fix symbolic ref validation Use the correct buffer when validating 'ref: refs/...' Signed-off-by: Jonas Fonseca <fonseca@diku.dk> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
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.

Junio C Hamano	a876ed83be	Use resolve_ref() to implement read_ref(). Symbolic refs are understood by resolve_ref(), so existing read_ref() users will automatically understand them as well. Signed-off-by: Junio C Hamano <junio@twinsun.com>	19 years ago
Linus Torvalds	ca8db1424d	[PATCH] Allow reading "symbolic refs" that point to other refs This extends the ref reading to understand a "symbolic ref": a ref file that starts with "ref: " and points to another ref file, and thus introduces the notion of ref aliases. This is in preparation of allowing HEAD to eventually not be a symlink, but one of these symbolic refs instead. [jc: Linus originally required the prefix to be "ref: " five bytes and nothing else, but I changed it to allow and strip any number of leading whitespaces to match what update-ref.c does.] Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Matt Draisey	a7e66ae3f7	[PATCH] Make do_each_ref() follow symlinks. Because there is no reason not to, and this makes things a bit safer when running "git prune". [jc: I do not necessarily agree with the reasoning of the original author that it is a good way to keep "git prune" from stomping on objects to have a symlink that points at .git/refs of the repository A in the .git/refs of the repository B when repository A borrows object database from repository B. For one thing, the object database that everybody borrows objects from may not even have its own .git/refs hierarchy. Come to think of it, maybe we should disallow symlink inside .git/refs hierarchy; we update the files there by creat/rename pair, so having symlinks would not work anyway when you do anything that would update them.] Signed-off-by: Junio C Hamano <junkio@cox.net>	20 years ago
Timo Sirainen	4ec99bf080	[PATCH] -Werror fixes GCC's format __attribute__ is good for checking errors, especially with -Wformat=2 parameter. This fixes most of the reported problems against 2005-08-09 snapshot.	20 years ago
Linus Torvalds	99a0a6e09f	Make "for_each_ref()" always use the "canonical" refname. It always uses a git-relative pathname, ie "refs/heads/master" instead of ".git/refs/heads/master" or whatever your GIT_DIR might be. This way when we send refs back-and-forth between repositories, there's never any question about GIT_DIR on either side.	20 years ago
Linus Torvalds	2f34ba32dd	Fix silly thinko in "head_ref()" It did a "for_each_ref()" in addition to the HEAD case, which was a left-over from an early broken test.	20 years ago
Linus Torvalds	723c31fea2	Add "git_path()" and "head_ref()" helper functions. "git_path()" returns a static pathname pointer into the git directory using a printf-like format specifier. "head_ref()" works like "for_each_ref()", except for just the HEAD.	20 years ago
Linus Torvalds	6cada6a98d	Clean up output of "for_each_ref()" when GIT_DIR is "." Remove the "./" at the head, it just looks much nicer.	20 years ago
Linus Torvalds	944d858969	Fix up "for_each_ref()" to be more usable, and use it in git-fsck-cache It needed to take the GIT_DIR information into account, something that the original receive-pack usage just never cared about.	20 years ago
Linus Torvalds	8a65ff7666	Generalize the "show each ref" code in receice-pack This turns it into a generic "do xyz for each ref" library function.	20 years ago
Daniel Barkalow	95fc75129a	[PATCH] Operations on refs This patch adds code to read a hash out of a specified file under {GIT_DIR}/refs/, and to write such files atomically and optionally with an compare and lock.
