There's complex rules governing whether a push is allowed to take place depending on whether we're pushing to refs/heads/*, refs/tags/* or refs/not-that/*. See is_branch() in refs.c, and the various assertions in refs/files-backend.c. (e.g. "trying to write non-commit object %s to branch '%s'"). This documentation has never been quite correct, but went downhill afterdbfeddb12e("push: require force for refs under refs/tags/", 2012-11-29) when we started claiming that <dst> couldn't be a tag object, which is incorrect. After some of the logic in that patch was changed in256b9d70a4("push: fix "refs/tags/ hierarchy cannot be updated without --force"", 2013-01-16) the docs weren't updated, and we've had some version of documentation that confused whether <src> was a tag or not with whether <dst> would accept either an annotated tag object or the commit it points to. This makes the intro somewhat more verbose & complex, perhaps we should have a shorter description here and split the full complexity into a dedicated section. Very few users will find themselves needing to e.g. push blobs or trees to refs/custom-namespace/* (or blobs or trees at all), and that could be covered separately as an advanced topic.

NAME

|
|
gitrevisions - Specifying revisions and ranges for Git
|
|
|
|
SYNOPSIS
|
|
--------
|
|
gitrevisions
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
Many Git commands take revision parameters as arguments. Depending on
|
|
the command, they denote a specific commit or, for commands which
|
|
walk the revision graph (such as linkgit:git-log[1]), all commits which are
|
|
reachable from that commit. For commands that walk the revision graph one can
|
|
also specify a range of revisions explicitly.
|
|
|
|
In addition, some Git commands (such as linkgit:git-show[1] and
|
|
linkgit:git-push[1]) can also take revision parameters which denote
|
|
other objects than commits, e.g. blobs ("files") or trees
|
|
("directories of files").
