Hi,
Say I have a repository which has a series of refs in a heirarchy such
as a gerrit repository with changes specified something like:
refs/changes/96/55596/3
refs/changes/96/55596/4
refs/changes/96/57496/1
refs/changes/96/57496/2
refs/changes/96/69796/1
refs/changes/96/69796/2
refs/changes/96/71696/1
refs/changes/96/71696/2
refs/changes/97/40197/1
refs/changes/97/40197/2
refs/changes/97/40197/3
refs/changes/97/40197/4
...
refs/changes/97/71697/2
refs/changes/97/71697/3
refs/changes/98/47298/1
refs/changes/98/47298/2
refs/changes/98/47298/3
refs/changes/98/57298/1
refs/changes/98/57298/2
refs/changes/98/73598/1
refs/changes/99/44099/1
refs/changes/99/69299/1
Is it possible to specify a refspec such that all of these will be
fetched? I tried doing
+refs/changes/*:refs/changes/*
but this doesn't work since the * can only be one portion of a refspec
The problem is that I would like to be able to pull all of these
changes in a git mirror so that I can reduce network traffic I use to
the gerrit server, by updating my local copy once and using the local
copy on the other tasks I need. This is necessary since the gerrit
server is (a) far away and (b) closes my connection when I have too
many requests.
But, git clone --mirror and git fetch have failed to pull every ref,
and only end up with heads and tags.
Regards,
Jake

I am not sure if I follow. With refs/heads/*:refs/remotes/origin/*
(e.g. following git://github.com/gitster/git for example), I am
reasonably sure you would get my refs/heads/jk/notes-dwim-doc and
other topics you authored without the slash between jk and
notes-dwim-doc getting in the way.

That appears to be correct, but.. why doesn't:
git fetch origin +refs/changes/*:refs/changes/*
seem to anything at all?
Ideally this owuld fetch all the remote refs in refs/changes and stick
them into my refs, but it appears to do nothing at all.

Jake

Infact, even running
git fetch origin +refs/changes/98/73598/1:refs/changes/98/73598/1
does not end up placing anything into refs/changes?
Is it because it happens to not be known by git? That seems rather
short sighted...

It turns out that it *does* pull the refs, but they don't appear to
show up inside the "refs" folder.. is there a reason for this?
ie:
ls .git/refs/changes
shows nothing,but
git ls-remote file:///path/to/repo
does show them? Any particular reason for why this is? I am confused
why refs aren't showing up inside the refs folder...

Jake

Does
git for-each-ref refs/changes/
in your local resulting repository show them?
There is nothing that says "ls -R .git/refs/" is the way to
enumerate available refs (in fact it is a _wrong_ way that is
guaranteed to give you wrong results).
Hint: .git/packed-refs

Yep I figured that out :) Now I know better!

So, sorry for the list spam. Things work correctly, it just is using
packed-refs, which is a feature I wasn't aware of :) Git already did
what I expected but in a way I did not, so I was very confused.
