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.

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).

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>
