* Teach send-pack a mirror modeAndy Whitcroft2007-11-09
| | | | | | | | | | | | | | | | | | Existing "git push --all" is almost perfect for backing up to another repository, except that "--all" only means "all branches" in modern git, and it does not delete old branches and tags that exist at the back-up repository that you have removed from your local repository. This teaches "git-send-pack" a new "--mirror" option. The difference from the "--all" option are that (1) it sends all refs, not just branches, and (2) it deletes old refs you no longer have on the local side from the remote side.

* Miscellaneous const changes and utilitiesDaniel Barkalow2007-11-02
| | | | | | | | | | | | | | | | | | | | | | The list of remote refs in struct transport should be const, because builtin-fetch will get confused if it changes. The url in git_connect should be const (and work on a copy) instead of requiring the caller to copy it. match_refs doesn't modify the refspecs it gets. get_fetch_map and get_remote_ref don't change the list they get. Allow transport get_refs_list methods to modify the struct transport. Add a function to copy a list of refs, when a function needs a mutable copy of a const list. Add a function to check the type of a ref, as per the code in connect.c Signed-off-by: Daniel Barkalow <barkalow@iabervon.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* git-fetch: do not fail when remote branch disappearsJunio C Hamano2007-10-28
| | | | | | | | | | | | | | | | When the branch named with branch.$name.merge is not covered by the fetch configuration for the remote repository named with branch.$name.remote, we automatically add that branch to the set of branches to be fetched. However, if the remote repository does not have that branch (e.g. it used to exist, but got removed), this is not a reason to fail the git-fetch itself. The situation however will be noticed if git-fetch was called by git-pull, as the resulting FETCH_HEAD would not have any entry that is marked for merging.

| * Prevent send-pack from segfaulting when a branch doesn't matchShawn O. Pearce2007-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If `git push url foo` can't find a local branch named foo we can't match it to any remote branch as the local branch is NULL and its name is probably at position 0x34 in memory. On most systems that isn't a valid address for git-send-pack's virtual address space and we segfault. If we can't find a source match and we have no destination we need to abort the match function early before we try to match the destination against the remote. Signed-off-by: Shawn O.

| * Cleanup unnecessary break in remote.cShawn O. Pearce2007-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This simple change makes the body of "case 0" easier to read; no matter what the value of matched_src is we want to break out of the switch and not fall through. We only want to display an error if matched_src is NULL, as this indicates there is no local branch matching the input. Also modified the default case's error message so it uses one less line of text. Even at 8 column per tab indentation we still don't break 80 columns with this new formatting. Signed-off-by: Shawn O.

| * Correct handling of branch.$name.merge in builtin-fetchShawn O. Pearce2007-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My prior bug fix for git-push titled "Don't configure remote "." to fetch everything to itself" actually broke t5520 as we were unable to evaluate a branch configuration of: [branch "copy"] remote = . merge = refs/heads/master as remote "." did not have a "remote...fetch" configuration entry to offer up refs/heads/master as a possible candidate available to be fetched and merged. In shell script git-fetch and prior to the above mentioned commit this was hardcoded for a url of "." to be the set of local branches. Chasing down this bug led me to the conclusion that our prior behavior with regards to branch.$name.merge was incorrect. In the shell script based git-fetch implementation we only fetched and merged a branch if it appeared both in branch.$name.merge *and* in remote.$r.fetch, where $r = branch.$name.remote. In other words in the following config file: [remote "origin"] url = git://git.kernel.org/pub/scm/git/git.git fetch = refs/heads/master:refs/remotes/origin/master [branch "master"] remote = origin merge = refs/heads/master [branch "pu"] remote = origin merge = refs/heads/pu Attempting to run `git pull` while on branch "pu" would always give the user "Already up-to-date" as git-fetch did not fetch pu and thus did not mark it for merge in .git/FETCH_HEAD. The configured merge would always be ignored and the user would be left scratching her confused head wondering why merge did not work on "pu" but worked fine on "master". If we are using the "default fetch" specification for the current branch and the current branch has a branch.$name.merge configured we now union it with the list of refs in remote.$r.fetch. This way the above configuration does what the user expects it to do, which is to fetch only "master" by default but when on "pu" to fetch both "master" and "pu". This uncovered some breakage in the test suite where old-style Cogito branches (.git/branches/$r) did not fetch the branches listed in .git/config for merging and thus did not actually merge them if the user tried to use `git pull` on that branch. Junio and I discussed it on list and felt that the union approach here makes more sense to DWIM for the end-user than silently ignoring their configured request so the test vectors for t5515 have been updated to include for-merge lines in .git/FETCH_HEAD where they have been configured for-merge in .git/config. Since we are now performing a union of the fetch specification and the merge specification and we cannot allow a branch to be listed twice (otherwise it comes out twice in .git/FETCH_HEAD) we need to perform a double loop here over all of the branch.$name.merge lines and try to set their merge flag if we have already schedule that branch for fetching by remote.$r.fetch. If no match is found then we must add new specifications to fetch the branch but not store it as no local tracking branch has been designated. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
| * builtin-fetch: Don't segfault on "fetch +foo"Shawn O. Pearce2007-09-19
| | | | | | | | | | | | | | | | | | If we are fetching something and were configured to do a forced fetch and have no local ref to store the fetched object into we cannot mark the local ref as having a forced update. Instead we should just silently discard the + request. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
| * Don't configure remote "." to fetch everything to itselfShawn O. Pearce2007-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we are talking about a remote URI of "." we are really talking about *this* repository that we are fetching into or pushing out of. There are no matching tracking branches for this repository; we do not attempt to map a ref back to ourselves as this would either create an infinite cycle (for example "fetch = +refs/*:refs/mine/*") or it causes problems when we attempt to push back to ourselves. So we really cannot setup a remote like this: [remote "."] url = . fetch = +refs/*:refs/* In the case of `git push . B:T` to fast-forward branch T to B's current commit git-send-pack will update branch T to B, assuming that T is the remote tracking branch for B. This update is performed immediately before git-send-pack asks git-receive-pack to perform the same update, and git-receive-pack then fails because T is not where git-send-pack told it to expect T to be at. In the case of `git fetch .` we really should do the same thing as `git fetch $otherrepo`, that is load .git/FETCH_HEAD with the commit of HEAD, so that `git pull .` will report "Already up-to-date". We have always behaved like this before on this insane request and we should at least continue to behave the same way. With the above (bad) remote configuration we were instead getting fetch errors about funny refs, e.g. "refs/stash". Signed-off-by: Shawn O.

* | send-pack: respect '+' on wildcard refspecsJeff King2007-10-19
|/ | | | | | | | | | | | When matching source and destination refs, we were failing to pull the 'force' parameter from wildcard refspecs (but not explicit ones) and attach it to the ref struct.

* Add for_each_remote() function, and extend remote_find_tracking()Johannes Schindelin2007-07-11
| | | | | | | | | | | | | | | | The function for_each_remote() does exactly what the name suggests. The function remote_find_tracking() was extended to be able to search remote refs for a given local ref. The caller sets either src or dst (but not both) in the refspec parameter, and remote_find_tracking() will fill in the other and return 0. Both changes are required for the next step: simplification of git-branch's --track functionality.

* "git-push $URL" without refspecs pushes only matching branchesJunio C Hamano2007-07-02
| | | | | | | | | | | | | | When "git push" is run without any refspec (neither on the command line nor in the config), we used to push "matching refs" in the sense that anything under refs/ hierarchy that exist on both ends were updated. This used to be a sane default for publishing your repository to another back when we did not have refs/remotes/ hierarchy, but it does not make much sense these days. This changes the semantics to push only "matching branches". Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier, when the local repository has a branch "frotz" and the remote repository has a tag "frotz" (but not branch "frotz"), "git-push frotz" mistakenly updated the tag at the remote side. This was because the partial refname matching code was applied independently on both source and destination side. With this fix, when a colon-less refspec is given to git-push, we first match it with the refs in the source repository, and update the matching ref in the destination repository.

| * remote.c: fix "git push" weak match disambiguationJunio C Hamano2007-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When "git push A:B" is given, and A (or B) is not a full refname that begins with refs/, we require an unambiguous match with an existing ref. For this purpose, a match with a local branch or a tag (i.e. refs/heads/A and refs/tags/A) is called a "strong match", and any other match is called a "weak match". A partial refname is unambiguous when there is only one strong match with any number of weak matches, or when there is only one weak match and no other match. However, as reported by Sparse with Ramsay Jones recently, count_refspec_match() function had a bug where a variable in an inner block masked a different variable of the same name, which caused the weak matches to be ignored. This fixes it, and adds tests for the fix. Signed-off-by: Junio C Hamano <gitster@pobox.com>
