receive-pack: detect aliased updates which can occur with symrefs When pushing to a remote repo the sending side filters out aliased updates (e.g., foo:baz bar:baz). However, it is not possible for the sender to know if two refs are aliased on the receiving side via symrefs. Here is one such scenario: $ git init origin $ (cd origin && touch file && git add file && git commit -a -m intial) $ git clone --bare origin origin.git $ rm -rf origin $ git clone origin.git client $ git clone --mirror client backup.git && $ (cd backup.git && git remote set-head origin --auto) $ (cd client && git remote add --mirror backup ../backup.git && echo change1 > file && git commit -a -m change1 && git push origin && git push backup ) The push to backup fails with: Counting objects: 5, done. Writing objects: 100% (3/3), 244 bytes, done.

upload/receive-pack: allow hiding ref hierarchies A repository may have refs that are only used for its internal bookkeeping purposes that should not be exposed to the others that come over the network. Teach upload-pack to omit some refs from its initial advertisement by paying attention to the uploadpack.hiderefs multi-valued configuration variable. Do the same to receive-pack via the receive.hiderefs variable. As a convenient short-hand, allow using transfer.hiderefs to set the value to both of these variables. Any ref that is under the hierarchies listed on the value of these variable is excluded from responses to requests made by "ls-remote", "fetch", etc. (for upload-pack) and "push" (for receive-pack). Because these hidden refs do not count as OUR_REF, an attempt to fetch objects at the tip of them will be rejected, and because these refs do not get advertised, "git push :" will not see local branches that have the same name as them as "matching" ones to be sent. An attempt to update/delete these hidden refs with an explicit refspec, e.g. "git push origin :refs/hidden/22", is rejected. This is not a new restriction. To the pusher, it would appear that there is no such ref, so its push request will conclude with "Now that I sent you all the data, it is time for you to update the refs. I saw that the ref did not exist when I started pushing, and I want the result to point at this commit". The receiving end will apply the compare-and-swap rule to this request and rejects the push with "Well, your update request conflicts with somebody else; I see there is such a ref.", which is the right thing to do. Otherwise a push to a hidden ref will always be "the last one wins", which is not a good default. Signed-off-by: Junio C Hamano <gitster@pobox.com>

filter_ref: make a copy of extra "sought" entries If the server supports allow_tip_sha1_in_want, we add any unmatched raw-sha1 entries in our "sought" list of refs to the list of refs we will ask the other side for. We do so by inserting the original "struct ref" directly into our list, rather than making a copy. This has several problems. The most minor problem is that one cannot ever free the resulting list; it contains structs that are copies of the remote refs (made earlier by fetch_pack) along with sought refs that are referenced elsewhere. But more importantly that we set the ref->next pointer to NULL, chopping off the remainder of any existing list that the ref was a part of. We get the set of "sought" refs in an array rather than a linked list, but that array is often in turn generated from a list. The test modification in t5516 demonstrates this. Rather than fetching just an exact sha1, we fetch that sha1 plus another ref: - we build a linked list of refs to fetch when do_fetch calls get_ref_map; the exact sha1 is first, followed by the named ref ("refs/heads/extra" in this case). - we pass that linked list to transport_fetch_ref, which squashes it into an array of pointers - that array goes to fetch_pack, which calls filter_ref. There we generate the want list from a mix of what the remote side has advertised, and the "sought" entry for the exact sha1. We set the sought entry's "next" pointer to NULL. - after we return from transport_fetch_refs, we then try to update the refs by following the linked list. But our list is now truncated, and we do not update refs/heads/extra at all. We can fix this by making a copy of the ref. There's nothing that fetch_pack does to it that must be reflected in the original "sought" list (and indeed, if that were the case we would have a serious bug, because it is only exact-sha1 entries which are treated this way).

push: use remote.$name.push as a refmap Since f2690487 (fetch: opportunistically update tracking refs, 2013-05-11), we stopped taking a non-storing refspec given on the command line of "git fetch" literally, and instead started mapping it via remote.$name.fetch refspecs. This allows $ git fetch origin master from the 'origin' repository, which is configured with [remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* to update refs/remotes/origin/master with the result, as if the command line were $ git fetch origin +master:refs/remotes/origin/master to reduce surprises and improve usability. Before that change, a refspec on the command line without a colon was only to fetch the history and leave the result in FETCH_HEAD, without updating the remote-tracking branches. When you are simulating a fetch from you by your mothership with a push by you into your mothership, instead of having: [remote "satellite"] fetch = +refs/heads/*:refs/remotes/satellite/* on the mothership repository and running: mothership$ git fetch satellite you would have: [remote "mothership"] push = +refs/heads/*:refs/remotes/satellite/* on your satellite machine, and run: satellite$ git push mothership Because we so far did not make the corresponding change to the push side, this command: satellite$ git push mothership master does _not_ allow you on the satellite to only push 'master' out but still to the usual destination (i.e. refs/remotes/satellite/master). Implement the logic to map an unqualified refspec given on the command line via the remote.$name.push refspec. This will bring a bit more symmetry between "fetch" and "push".

push: use remote.$name.push as a refmap Since f2690487 (fetch: opportunistically update tracking refs, 2013-05-11), we stopped taking a non-storing refspec given on the command line of "git fetch" literally, and instead started mapping it via remote.$name.fetch refspecs. This allows $ git fetch origin master from the 'origin' repository, which is configured with [remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* to update refs/remotes/origin/master with the result, as if the command line were $ git fetch origin +master:refs/remotes/origin/master to reduce surprises and improve usability. Before that change, a refspec on the command line without a colon was only to fetch the history and leave the result in FETCH_HEAD, without updating the remote-tracking branches. When you are simulating a fetch from you by your mothership with a push by you into your mothership, instead of having: [remote "satellite"] fetch = +refs/heads/*:refs/remotes/satellite/* on the mothership repository and running: mothership$ git fetch satellite you would have: [remote "mothership"] push = +refs/heads/*:refs/remotes/satellite/* on your satellite machine, and run: satellite$ git push mothership Because we so far did not make the corresponding change to the push side, this command: satellite$ git push mothership master does _not_ allow you on the satellite to only push 'master' out but still to the usual destination (i.e. refs/remotes/satellite/master). Implement the logic to map an unqualified refspec given on the command line via the remote.$name.push refspec. This will bring a bit more symmetry between "fetch" and "push".
