More interestingly, if you have
push = +refs/heads/*:refs/remotes/satellite/*
in your configuration and then said
$ git push mothership master
then configured remote.mothership.push is not even used (I bring
this up because "export" is more closely related to "push" than
This (and why 'next' and 'pu' are not fetched in the "fetch"
example) is because traditionally, refspecs that are explicitly
given on the command line overrides configured ones (in other words,
configured ones are used as a fallback default).
This is a bit of tangent, but since the recent discussion on the
triangular workflows, I've been wondering if we may want to have a
new way to configure things so that we can say "When I push to
mothership any one of my local branches, I want it to go to the ref
with the same name at the mothership under refs/remotes/satellite/
hierarchy (because I am emulating 'git fetch' that is run on the
mothership to get updates from this satellite)", somewhat similar to
what you added to "fast-export" via the option in question.
But we cannot achieve that mapping by changing the meaning of the
configured refspecs remote.mothership.push without having to worry
about breaking existing practices of people. When they say "git
push mothership master", they do mean to push refs/heads/master to
refs/heads/master, and it will break the expectation in their
existing repositories if we change the semantics under them.
A possible way to achieve that mapping "When I push to mothership
any one of my local branches,..." could be to introduce a _new_
configuration (so that existing repositories will not suddenly
change their behaviour):
pushmap = +refs/heads/*:refs/remotes/satellite/*
And then we can allow this command line
$ git push mothership master
to be affected by the mapping when expanding the short-hand refspecs
given on the command line. Traditionally, anything without colon
stood as a short-hand for "push to the same name", e.g. 'master' is
for 'refs/heads/master:refs/heads/master' in this example, and
'v1.0' would be for 'refs/tags/v1.0:refs/tags/v1.0'.
But it does not have to stay that way. In order to move things
forward in that direction, this new configuration has to be
distinguishable from the traditional "refspec", as it embodies a
