t/t5515-fetch-merge-logic.sh: Added tests for the merge login in git-fetch Signed-off-by: Santi Béjar <sbejar@gmail.com> Signed-off-by: Junio C Hamano <junkio@cox.net> 2007-03-05 09:09:39 +01:00			`# br-branches-default-merge`
Correct handling of branch.$name.merge in builtin-fetch My prior bug fix for git-push titled "Don't configure remote "." to fetch everything to itself" actually broke t5520 as we were unable to evaluate a branch configuration of: [branch "copy"] remote = . merge = refs/heads/master as remote "." did not have a "remote...fetch" configuration entry to offer up refs/heads/master as a possible candidate available to be fetched and merged. In shell script git-fetch and prior to the above mentioned commit this was hardcoded for a url of "." to be the set of local branches. Chasing down this bug led me to the conclusion that our prior behavior with regards to branch.$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.

write first for-merge ref to FETCH_HEAD first The FETCH_HEAD refname is supposed to refer to the ref that was fetched and should be merged. However all fetched refs are written to .git/FETCH_HEAD in an arbitrary order, and resolve_ref_unsafe simply takes the first ref as the FETCH_HEAD, which is often the wrong one, when other branches were also fetched. The solution is to write the for-merge ref(s) to FETCH_HEAD first. Then, unless --append is used, the FETCH_HEAD refname behaves as intended. If the user uses --append, they presumably are doing so in order to preserve the old FETCH_HEAD. While we are at it, update an old example in the read-tree documentation that implied that each entry in FETCH_HEAD only has the object name, which is not true for quite a while.

fetch: do not store peeled tag object names in FETCH_HEAD We do not want to record tags as parents of a merge when the user does "git pull $there tag v1.0" to merge tagged commit, but that is not a good enough excuse to peel the tag down to commit when storing in FETCH_HEAD.
