Bummer.
Well, Mike (XEmacs's Mercurial champion) accuses Tailor of abusing the Mercurial APIs. He has a point, although my worries retain some validity, I think.
I'm about to head up to New York City for the day, so just a
quick note of thanks for taking a look at this. Once you're done
will we be able to get a bzr branch from Tailor or will we have to do
another import?
I'm not sure what you mean. I don't think it's a good idea to go svn->hg->bzr, if that's what you mean; there's some degradation of metadata in each transition. I'll give a Tailor svn->bzr conversion a shot. Let me know what you want to do about giving "concerned parties" access to them (I presume you don't want them sitting on a Googlable webserver at this point).
Please note that no conversion has taken as much as three hours. One svn rev per second seems to be the going rate for all of the conversion tools I've tried, and the initialization from the svn log takes only a few seconds.
IOW, I can surely make full imports faster than you can evaluate them.<wink> The question will be preserving or injecting desired metadata (eg, sensible summary logs, user id mapping), which for most tools will take some hacking.
Please keep us up to date about how it goes.
OK, at this point, I've temporarily given up on Tailor for svn->hg. There's a locking deadlock (I think) in Mercurial at about r7721, and it will take some time to diagnose that.
I did get both a full trunk conversion and a "trunk/mailman" only conversion from the hgsvn tool (which is just a one-way sync, svn to hg). hgsvn has the advantage of being a PyPI project. easy_install hgsvn if somebody wants to try. (If you don't have easy_install, you can get it from http://peak.telecommunity.com/DevCenter/EasyInstall.)
I also tried Eric Hopper's svn2hg (there are a couple of tools by that name). It looks well-coded, but it's not ready for general use.
