git-core-1.5.5.5-alt1 "man git-push" says: --mirror Instead of naming each ref to push, specifies that all refs under $GIT_DIR/refs/heads/ and $GIT_DIR/refs/tags/ be mirrored to the remote repository. Newly created local refs will be pushed to the remote end, locally updated refs will be force updated on the remote end, and deleted refs will be removed from the remote end. But the actual behavior is different: it sends *all* refs, including remotes. The actual behavior is not convenient: it results--in the mirror repository--in superfluous remote refs duplicating the same repository under the given name. Demonstration (pay attention to the second turn of "git push", which sends refs/remotes/copy/master): [ivan@arrakis data]$ mkdir -v ~/test-git-mirror-remotes mkdir: создан каталог `/home/ivan/test-git-mirror-remotes' [ivan@arrakis data]$ cd ~/test-git-mirror-remotes [ivan@arrakis test-git-mirror-remotes]$ git init Initialized empty Git repository in .git/ [ivan@arrakis test-git-mirror-remotes]$ echo a > a [ivan@arrakis test-git-mirror-remotes]$ git add a [ivan@arrakis test-git-mirror-remotes]$ git commit -m 'First.'

Workaround: do not use "--mirror", use "refs/heads/*:refs/heads/* --tags" instead.
Another workaround: add push = refs/heads/*:refs/heads/* push = refs/tags/*:refs/tags/* to the corresponding "remote" section in .git/config, if you want that "push" to that repositary by default acts as "push --mirror" should to (as described in the manpage).

A discussion of this issue in the "git" list -- http://osdir.com/ml/git/2009-05/msg00701.html ; Junio Hamano: "But these other people can say "git fetch $here remotes/origin/master" explicitly when fetching from this repository. By mirroring everything under refs/ to its --mirror backup repository, these other people can substitute $here with its --mirror backup repository and expect it to still work. It would be a regression if you stop pushing the refs/remotes hierarchy"

В 4.1/branch исправления не будут вноситься уже технически (заглушена очередь на сборку), поэтому прошу ошибки, актуальные для sisyphus/p7/t7, перевесить на текущие ветки или сизиф.
