* remote.c: do not trigger remote.<name>.<var> codepath for two-level namesJohannes Sixt2009-04-24
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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 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.

* make sure parsed wildcard refspec ends with slashJunio C Hamano2008-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Reword "your branch has diverged..." lines to reduce line lengthAvery Pennarun2008-07-16
| | | | | | | | | | | | | 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. This patch rewords the messages to make the lines generally shorter, so that you'd need a significantly longer branch name to trigger the problem.

* stat_tracking_info(): clear object flags used during countingJunio C Hamano2008-07-03
| | | | | | | | | When left-right traversal counts the commits in a diverged history, it leaves the flags in the commits smudged, and we need to clear them before we return. Otherwise the caller cannot inspect other branches with this function again. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Refactor "tracking statistics" code used by "git checkout"Junio C Hamano2008-07-02
| | | | | | | | | | | | | | | | | | | | 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.
