Junio C Hamano	a2f9fe92eb	lock_any_ref_for_update(): do not accept malformatted refs. We used to use lock_any_ref_for_update() because the command needs to also update HEAD (which is not under refs/, so lock_ref_sha1() cannot be used). The function however did not check for refs with illegal characters in them. Use check_ref_format() to catch malformed refs. For this check, we specifically do not want to say having less than two levels in the name is illegal to allow HEAD (and perhaps other special refs in the future).

Junio C Hamano	01754769ab	Don't force everybody to call setup_ident(). Back when only handful commands that created commit and tag were the only users of committer identity information, it made sense to explicitly call setup_ident() to pre-fill the default value from the gecos information. But it is much simpler for programs to make the call automatic when get_ident() is called these days, since many more programs want to use the information when updating the reflog.

Junio C Hamano	7f9acb2a16	git-merge: leave sensible reflog message when used as the first level UI. It used to throw potentially multi-line log message at reflog. Just record the heads that were given to be merged at the command line and the action. Revert the removal of the check in "git-update-ref -m" I made earlier which was only a work-around for this.

Junio C Hamano	8ac65937d0	Make sure we do not write bogus reflog entries. The file format dictates that entries are LF terminated so the message cannot have one in it. Chomp the message to make sure it only has a single line if necessary, while removing the leading whitespace. Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Junio C Hamano	ac5409e420	update-ref: -d flag and ref creation safety. This adds -d flag to update-ref to allow safe deletion of ref. Before deleting it, the command checks if the given <oldvalue> still matches the value the caller thought the ref contained. Similarly, it also accepts 0{40} or an empty string as <oldvalue> to allow safe creation of a new ref. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
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	a8e0d16d85	Convert memset(hash,0,20) to hashclr(hash). In the same spirit as hashcmp() and hashcpy(). Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Linus Torvalds	a633fca0c0	Call setup_git_directory() much earlier This changes the calling convention of built-in commands and passes the "prefix" (i.e. pathname of $PWD relative to the project root level) down to them.

Shawn Pearce	0b0fe4a65d	Allow user.name and user.email to drive reflog entry. Apparently calling setup_ident() after git_config causes the user.name and user.email values read from the config file to be replaced with the data obtained from the host. This means that users who have setup their email address in user.email will instead be writing reflog entries with their hostname. Moving setup_ident() to before git_config in update-ref resolves this ordering problem. Signed-off-by: Shawn O.

Shawn Pearce	5b16b09021	Convert update-ref to use ref_lock API. This conversion also adds the '-m' switch to update-ref allowing the caller to record why the ref is changing. At present this is merely copied down into the ref_lock API. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago

Alex Riesen	08db81a9f1	allow git-update-ref create refs with slashes in names Make git-update-ref create references with slashes in them. git-branch and git-checkout already support such reference names. git-branch can use git-update-ref to create the references in a more formal manner now.

Petr Baudis	ad7db62113	Fix confusing git-update-ref error message When git-update-ref has hit the "Ref %s changed to %s" error, I just stare at it, left puzzled.

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
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>	20 years ago
Junio C Hamano	9b143c6e15	Teach update-ref about a symbolic ref stored in a textfile. A symbolic ref is a regular file whose contents is "ref:", followed by optional leading whitespaces, followed by a GIT_DIR relative pathname, followed by optional trailing whitespaces (the optional whitespaces are unconditionally removed, so you cannot have leading nor trailing whitespaces). This can be used in place of a traditional symbolic link .git/HEAD that usually points at "refs/heads/master". You can instead have a regular file .git/HEAD whose contents is "ref: refs/heads/master". [jc: currently the code does not enforce the symbolic ref to begin with refs/, unlike the symbolic link case. It may be worthwhile to require either case to begin with refs/ and not have any /./ nor /../ in them.] Signed-off-by: Junio C Hamano <junkio@cox.net>	20 years ago

Linus Torvalds	66bf85a462	[PATCH] Add "git-update-ref" to update the HEAD (or other) ref This is a careful version of the script stuff that currently just blindly writes HEAD with a new value. You can use git-update-ref HEAD <newhead> or git-update-ref HEAD <newhead> <oldhead> where the latter version verifies that the old value of HEAD matches oldhead. It basically allows a "ref" file to be a symbolic pointer to another ref file by starting with the four-byte header sequence of "ref:". More importantly, it allows the update of a ref file to follow these symbolic pointers, whether they are symlinks or these "regular file symbolic refs". NOTE! It follows _real_ symlinks only if they start with "refs/": otherwise it will just try to read them and update them as a regular file (ie it will allow the filesystem to follow them, but will overwrite such a symlink to somewhere else with a regular filename). In general, using git-update-ref HEAD "$head" should be a _lot_ safer than doing echo "$head" > "$GIT_DIR/HEAD" both from a symlink following standpoint _and_ an error checking standpoint. The "refs/" rule for symlinks means that symlinks that point to "outside" the tree are safe: they'll be followed for reading but not for writing (so we'll never write through a ref symlink to some other tree, if you have copied a whole archive by creating a symlink tree).
