Hi,

I am trying to git-svn clone https://svn.calendarserver.org/repository/calendarserver/CalendarServer/ and I cannot say I am much succesful. Every couple of hundred of commits I get this:

RA layer request failed: REPORT of '/repository/calendarserver/!svn/vcc/default': could not connect to server (https://svn.calendarserver.org) at /usr/local/share/perl5/Git/SVN/Ra.pm line 290.

and git-svn stops. When restarting git svn fetch, it fetches another couple of hundred commits and then fails again. Given that there are 11000+ commits just in the trunk, I am afraid of a long long night. Did anybody managed to clone this repo? Or is there some way how to make git-svn more patient (this error means the SVN server is a bit flakey, right)?

Best,

Matěj

I have seen this behaviour, though never determined the root cause .Probably the simplest thing you can do without access to the server is to put your git svn fetch into a bash while loop, like so:

while ! git svn fetch; do :; done;

Of course, I did this, but still I wonder how much is the resulting git repository http://luther.ceplovi.cz/git/CalendarServer.git/ faithful representation of the original SVN one http://trac.calendarserver.org/. Would not be something missing?

Best,

Re: git-svn troubles with calendarserver SVN repo

My experience is that the fetch will be atomic - it either fetches an SVN commit or it doesn't.

Failure during dcommit is more painful and I usually find it is necessary to manually use a git rebase to rebase the commits that didn't make it to SVN on top of the commits that did.

Consider using (the somewhat experimental) git-remote-testsvn and the underlying contrib/svn-fe/. For starters, try:

  $ git clone testsvn::https://svn.calendarserver.org/repository/calendarserver/CalendarServer/

You might need to hack a bit to get it working properly, but you'll find that it's much faster than git-svn in the long-run.
