I’m trying to use Mercurial as a front end for Subversion, and have a strong interest in having all branches etc intact so I can see common changes etc.
However, all of my subversion repositories create rather large issues for mercurial (1.8 with TortoiseHg 2.0 unfortunately, the ppa’s seem to have deleted the older revisions…). The issues are varied and present far too much annoyance to list (or figure out).
How do I skip a svn revision that hg clone or hg pull complains about? Or do I just have to recursively get fewer and fewer revisions until I get a successful clone?
Also, I’ve tried working around this by exporting the patch from svn and applying it to my working directory; the exact same issue occurs (but at least now I’ve got something to look at…)
Issues I’m getting (but not specifically on topic for the question…)
Existing file overwrite attempt:
Achieved by hg init, set svn url and hg pull

[r5061] StephenK: Updated properties
/home/stephenk/hgsubversion/hgsubversion/wrappers.py:337: DeprecationWarning: BaseException.message has been deprecated as of Python 2.6
ui.status('%s\n' % e.message)
This Subversion server is older than 1.4.0, and cannot satisfy replay requests.
In light of that, I'll fall back and do diffs, but it won't do as good a job. You should really upgrade your server.

I’m on ubuntu, really want to have a ppa to manage it for me, and am getting frustrated with this interoperability. I’m thinking I may have to try a hg+git+svn double bridge or something
Consider upgrading the server to 1.4.x or later – things should work way way better then…
It looks (from the stack traces) like you’ve found some bugs in the diff+patch code we use to work around a lack of replay in old svn versions, but it’s impossible to know what the problem is without a test repo we can play with.
