Hi All
I am an Apache Synapse developer, and want to import the Synapse SVN
repo into Git, so that Ohloh can properly get the Synapse history
(http://www.ohloh.net/topics/1326?page=1#post_6287)
However, when I try the command: "git svn clone --trunk=trunk
--tags=tags --branches=branches http://svn.apache.org/repos/asf/synapse";
it seems to take forever, (or at least until the next network glitch),
and keeps filling up a file with just plain zeros ("0") :
./.git/svn/trunk/.rev_db.13f79535-47bb-0310-9956-ffa450edef68
The latest versions of git-svn should be vastly more space efficient
with .rev_map files.
Okay, besides the zero offset, there seems to be big problem with the
svn repo:
svn list -r 234478 http://svn.apache.org/repos/asf/synapse
branches/
site/
tags/
trunk/
svn list -r 234478 http://svn.apache.org/repos/asf|grep synapse
Ah, that's because it started off in the /incubator directory, not /synapse:
$ svn log -v -r 234478 http://svn.apache.org/repos/asf
------------------------------------------------------------------------
r234478 | dims | 2005-08-22 05:39:51 -0700 (Mon, 22 Aug 2005) | 3 lines
Changed paths:
A /incubator/synapse/branches
A /incubator/synapse/site
A /incubator/synapse/tags
A /incubator/synapse/trunk
init synapse SVN
Yes, and later on there was some more moving around to
"webservices/synapse/synapse", ".../syaps2", ".../synapse" (i.e.
renaming "synapse/synapse" to "synapse") and then to the final destination.
Some svn client command know how to follow moves, other don't. I can't
make them return results by using peg revisions, but I don't know how
git-svn handles them.
------------------------------------------------------------------------
Right, nothing returned.
git-svn insists on using http://svn.apache.org/repos/asf as the base
URL, which is basically correct, but doesn't work for this repo.
Even editing .git/config and .git/svn/metadata (after git svn init,
befire the first fetch) to change the url doesn't help. git svn still
uses .../asf. Is this as intended? cc'ing the git svn author.
Can you try using the latest git-svn and also --no-follow-parent?
--no-follow-parent won't traverse copy history so it may be faster,
but you'll get an incomplete history.
On the other hand, it looks like the asf repo is hopelessly slow
for history retrieval.
I'm pulling the asf log (svn log -v http://svn.apache.org/repos/asf >
tmp.log) but it's taking forever... git-svn uses basically the same
operation as 'svn log -v' and I've yet to see an SVN server take this
long to show history.
I've gotten 70,000 revisions after over one hour with the above svn log
command. I'm going to restart this from a server with a better
connection since I need to power off this one when I sleep.
Note that I'm not the OP, I'm just a git-svn user who got curious about
that post. I think the asf repo shows exactly those mistakes which svn
drives its users into (and which I've made also, on a much smaller
scale, of course). As far as I understand, the synapse repo there is
historical, and they need to convert to git in order to feed it into a
CMS. I don't know if OP is still interested.
