I am aware of that.  However, nothing seems to prevent svn tags to be
mapped to tag refs insead of head refs.  Maybe both behaviours could be
available, if someone wants to be able to "commit to svn tags" properly
from git, but since that is probably not the common case, I would rather
see this current behaviour as an option.

But we are going off-topic here.  That "feature" of git-svn checking out
"the branch on which the last commit was done" is fortunately not being
documented in the manpage :).  The problem here (distinct from the
tag-handling issue) is that you can barely predict what svn remote your
master branch will track !

Exactly, that would simply be consistent.

svn allows you to commit to tags as if they were branches - indeed they
are branches just as much as svn branches are branches.

Therefore, git-svn represents svn tags as git remote branches (not
tags). After the clone is done, git-svn checks out the branch on which
the last commit was done.

So, git-svn is doing as it should, under the restrictions that svn puts
on its operations.

One may argue that master should point to trunk (for --stdlayout)
instead after git svn clone, just like master points to master after git
clone. But which one is "the correct branch"? I would claim that the
client cannot know and there should be no master (maybe a detached head
with the last commit, i.e. HEAD) but last I tried I remained a
1-person-minority ;)

Cheers,
Michael

[BUG] git-svn: HEAD pointing to a tag after cloning

[Yann Dirson]

The following happens with git 1.6.3.  For some reason git-svn sets HEAD
to the wrong branch.  Not sure what happens here, $self->full_url seems to
be used for a wrong purpose somewhere in the code.


(you can see a commit on the "tag" branch, which got committed at the
wrong place because the user did not notice that HEAD was not pointing to
the correct branch)
