On MacOS, 1.7.2, git svn clone seems to fail silently

On MacOS, 1.7.2, git svn clone seems to fail silently

[Benson Margulies]

git svn clone -s https://gate.svn.sourceforge.net/svnroot/gate

This worked with a previous version of git, I am sorry to report that
I don't know which one.

When I run it with GIT_TRACE=2, the trace ends with:

tace: built-in: git 'config' 'svn-remote.svn.branches-maxRev' '12912'
trace: built-in: git 'config' 'svn-remote.svn.tags-maxRev' '12912'
trace: built-in: git 'config' 'svn-remote.svn.branches-maxRev' '12912'
trace: built-in: git 'config' 'svn-remote.svn.tags-maxRev' '12912' trace:
built-in: git 'gc' '--auto'

I get none of the usual 'checked through' output, either.

that's all. No errors, no messages. No branches, no contents. Just the
wind whistling through the bytes.

Heh - you might be the one to figure out
http://thread.gmane.org/gmane.comp.version-control.git/134936

But first, it would be good to confirm:

 - if you run "echo $?" right after such a failure, what
   status code do you get?

 - what is the output of "git branch -r" when you finish?

Coping strategy: usually with "git svn clone" failures, you can resume
where you left off with "git svn fetch".

Good luck,
Jonathan

 I don't have $? at hand, but I can tell you that git branch -r says
 nothing, either. Also, running git fetch has the same result. Prints
 the same sort of trace lines if tracing, then does nothing

Yes, this seems different from the EPIPE bug, alas.

I get a core dump (for some small process, I don’t know what: 1048576
bytes.  Died of signal 5 in pthread_mutex_unlock) and git-svn is still
going.

I didn't realize that this email was the same as the gmane group and I
thus made an unhelpful reply to the other thread you pointed me at. I
apologize for the noise.

$? -> 0

The numbers in tags-maxRev don't go up with each 'fetch'.

Are you fetching to an already-existing repo? If you are, and it fails
relatively quickly, it'd be helpful if you could upload the repo
somewhere, so people can quickly test things (when I reproduced the
bug on Linux on a new clone, it took tens of minutes before failing).

Hello everyone.

There's a problem here, but not even remotely (pardon) the one I thought it was.

The right URL in this case with -s is
https://gate.svn.sourceforge.net/svnroot/gate/gate.

Note the extra /gate on the end.

It would be nice if this was diagnosed in fashion ("Dear user. That
doesn't look like a stdlayout svn directory) but the injury is mos def
self-inflicted.
