2009-04-24remote.c: do not trigger remote.<name>.<var> codepath for two-level namesLibravatar Johannes Sixt1-1/+1
If the config file contains a section like this: [remote] default = foo (it should be '[remotes]') then commands like git status git checkout git branch -v fail even though they are not obviously related to remotes. (These commands write "ahead, behind" information and, therefore, access the per-remote information). Unknown configuration keys should be ignored, not trigger errors.

2009-04-01Make local branches behave like remote branches when --trackedLibravatar Michael J Gruber1-2/+5
This makes sure that local branches, when followed using --track, behave the same as remote ones (e.g. differences being reported by git status and git checkout). This fixes 1 known failure. The fix is done within branch_get(): The first natural candidate, namely remote_find_tracking(), does not have all the necessary info because in general there is no remote struct for '.', and we don't want one because it would show up in other places as well. branch_get(), on the other hand, has access to merge_names[] (in addition to merge[]) and therefore can set up the followed branch easily.

2009-03-16Remove total confusion from git-fetch and git-pushLibravatar Junio C Hamano1-18/+3
The config file is not the only place remotes are defined, and without consulting .git/remotes and .git/branches, you won't know if "origin" is configured by the user. Don't give up too early and insult the user with a wisecrack "Where do you want to fetch from today?" The only thing the previous patch seems to want to prevent from happening is a lazy "git fetch/push" that does not say where-from/to to produce an error message 'origin not found', and we can do that by not letting add_url_alias() to turn a nickname "origin" literally into a pathname "origin" without changing the rest of the logic.

2009-03-10Give error when no remote is configuredLibravatar Daniel Barkalow1-3/+27
When there's no explicitly-named remote, we use the remote specified for the current branch, which in turn defaults to "origin". But it this case should require the remote to actually be configured, and not fall back to the path "origin". Possibly, the config file's "remote = something" should require the something to be a configured remote instead of a bare repository URL, but we actually test with a bare repository URL. In fetch, we were giving the sensible error message when coming up with a URL failed, but this wasn't actually reachable, so move that error up and use it when appropriate. In push, we need a new error message, because the old one (formerly unreachable without a lot of help) used the repo name, which was NULL.

2009-03-08Adjust js/remote-improvements and db/refspec-wildcard-in-the-middleLibravatar Junio C Hamano1-9/+136
The latter topic changes the definition of how refspec's src and dst side is stored in-core; it used to be that the asterisk for pattern was omitted, but now it is included. The former topic handcrafts an old style refspec to feed the refspec matching machinery that lacks the asterisk and triggers an error. This resolves the semantic clash between the two topics early before they need to be merged to integration branches. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-03-07Support '*' in the middle of a refspecLibravatar Daniel Barkalow1-7/+17
In order to keep the requirements strict, each * has to be a full path component, and there may only be one * per side.

2009-03-07Keep '*' in pattern refspecsLibravatar Daniel Barkalow1-15/+18
In order to do anything more capable with refspecs, the first step is to keep the entire input. Additionally, validate patterns by checking for the ref matching the rules for a pattern as given by check_ref_format(). This requires a slight change to check_ref_format() to make it enforce the requirement that the '*' immediately follow a '/'.

2009-03-04stat_tracking_info(): only count real commitsLibravatar Kjetil Barvik1-1/+2
stat_tracking_info() in remote.c is used to collect the statistics to be able to say (for instance) from the output of "git checkout': Your branch and 'foo' have diverged, and have X and Y different commit(s) each, respectively.

2009-02-27remote: make guess_remote_head() use exact HEAD lookup if it is availableLibravatar Jeff King1-0/+8
Our usual method for determining the ref pointed to by HEAD is to compare HEAD's sha1 to the sha1 of all refs, trying to find a unique match. However, some transports actually get to look at HEAD directly; we should make use of that information when it is available. Currently, only http remotes support this feature.

2009-02-27remote: make match_refs() not short-circuitLibravatar Jay Soffian1-2/+4
match_refs() returns non-zero if there is an error in match_explicit_refs(), without handling any remaining pattern ref specs. Its existing callers exit upon receiving non-zero, so a partial result is of no consequence to them; however a new caller, builtin-remote, is interested in the complete result even if there are errors in match_explicit_refs().

2009-02-27remote: make match_refs() copy src ref before assigning to peer_refLibravatar Jay Soffian1-2/+5
In some instances, match_refs() sets the peer_ref field of refs in the dst list such that it points to a ref in the src list. This prevents callers from freeing both the src and dst lists, as doing so would cause a double-free since free_refs() frees the peer_ref. As well, the following configuration causes two refs in the dst list to have the same peer_ref, which can also lead to a double-free: push = refs/heads/master:refs/heads/backup push = refs/heads/master:refs/heads/master Existing callers of match_heads() call it only once and then terminate, w/o ever bothering to free the src or dst lists, so this is not currently a problem. This patch modifies match_refs() to first copy any refs it plucks from the src list before assigning them as a peer_ref. This allows builtin-remote, a future caller, to free the src and dst lists.

2009-02-27remote: let guess_remote_head() optionally return all matchesLibravatar Jay Soffian1-10/+19
Determining HEAD is ambiguous since it is done by comparing SHA1s. In the case of multiple matches we return refs/heads/master if it matches, else we return the first match we encounter. builtin-remote needs all matches returned to it, so add a flag for it to request such. To be simple and consistent, the return value is now a copy (including peer_ref) of the matching refs. Originally contributed by Jeff King along with the prior commit as a single patch.

2009-02-27remote: make copy_ref() perform a deep copyLibravatar Jay Soffian1-5/+13
To ensure that copied refs can always be freed w/o causing a double-free, make copy_ref() perform a deep copy. Also have copy_ref() return NULL if asked to copy NULL to simplify things for the caller. Background: currently copy_ref() performs a shallow copy. This is fine for current callers who never free the result and/or only copy refs which contain NULL pointers. But copy_ref() is about to gain a new caller (guess_remote_head()) which copies refs where peer_ref is not NULL and the caller of guess_remote_head() will want to free the result.

2009-02-26remote: simplify guess_remote_head()Libravatar Jay Soffian1-23/+8
This function had complications which made it hard to extend. - It used to do two things: find the HEAD ref, and then find a matching ref, optionally returning the former via assignment to a passed-in pointer. Since finding HEAD is a one-liner, just have a caller do it themselves and pass it as an argument. - It used to manually search through the ref list for refs/heads/master; this can be a one-line call to find_ref_by_name.

With all calls to alloc_ref() gone, we can remove it and then we're free to give alloc_ref_from_str() the shorter name.

2008-07-27make sure parsed wildcard refspec ends with slashLibravatar Junio C Hamano1-18/+34
A wildcard refspec is internally parsed into a refspec structure with src and dst strings. Many parts of the code assumed that these do not include the trailing "/*" when matching the wildcard pattern with an actual ref we see at the remote. What this meant was that we needed to make sure not just that the prefix matched, and also that a slash followed the part that matched. But a codepath that scans the result from ls-remote and finds matching refs forgot to check the "matching part must be followed by a slash" rule. This resulted in "refs/heads/b1" from the remote side to mistakenly match the source side of "refs/heads/b/*:refs/remotes/b/*" refspec. Worse, the refspec crafted internally by "git-clone", and a hardcoded preparsed refspec that is used to implement "git-fetch --tags", violated this "parsed widcard refspec does not end with slash" rule; simply adding the "matching part must be followed by a slash" rule then would have broken codepaths that use these refspecs. This commit changes the rule to require a trailing slash to parsed wildcard refspecs. IOW, "refs/heads/b/*:refs/remotes/b/*" is parsed as src = "refs/heads/b/" and dst = "refs/remotes/b/". This allows us to simplify the matching logic because we only need to do a prefixcmp() to notice "refs/heads/b/one" matches and "refs/heads/b1" does not.

2008-07-16Reword "your branch has diverged..." lines to reduce line lengthLibravatar Avery Pennarun1-16/+10
The message length depends on the length of the branch name. In my case, the branch name "origin/add-chickens2" put the first line of the "your branch has diverged" message over 80 characters, which triggered "less -FS" to not exit automatically as expected.

People seem to like "Your branch is ahead by N commit" report made by "git checkout", but the interface into the statistics function was a bit clunky. This splits the function into three parts: * The core "commit counting" function that takes "struct branch" and returns number of commits to show if we are ahead, behind or forked; * Convenience "stat formating" function that takes "struct branch" and formats the report into a given strbuf, using the above function; * "checkout" specific function that takes "branch_info" (type that is internal to checkout implementation), calls the above function and print the formatted result. in the hope that the former two can be more easily reusable.
