RussianQuestion
I am working with a repository whose root has moved around some in its history (started at trunk/, moved to subproject/trunk). Right now I can either use hgsubversion to work with all the history up to the point when it moved to subproject/trunk (see https://bitbucket.org/durin42/hgsubversion/issue/135/move-tracking), or I can use hg convert or rebase to splice together the histories into one cohesive repository.
After splicing and calling hg svn rebuildmeta, hgsubversion is all confused. New revisions in the svn repository are pulled into a branch called "../".
Basically, I'm wondering if it's possible to tell hgsubversion to use a certain svn revision as its reference point, only attempting to sync up the histories from that point forward?
Here is a small test illustrating the issue (sorry for the DOS commands)
C:\hgtest>svnadmin create svnrepo
C:\hgtest>svn co file:///C:/hgtest/svnrepo svncheckout
Checked out revision 0.
C:\hgtest>cd svncheckout
C:\hgtest\svncheckout>mkdir trunk/
The syntax of the command is incorrect.
C:\hgtest\svncheckout>svn mkdir trunk
A trunk
C:\hgtest\svncheckout>cd trunk
C:\hgtest\svncheckout\trunk>echo "Test file version 1" > testfile.txt
C:\hgtest\svncheckout\trunk>cd ..
C:\hgtest\svncheckout>svn add trunk\testfile.txt
A trunk\testfile.txt
C:\hgtest\svncheckout>svn ci -m "Original version in trunk configuration"
Adding trunk
Adding trunk\testfile.txt
Transmitting file data .
Committed revision 1.
C:\hgtest\svncheckout>svn mkdir subproject

C:\hgtest\svncheckout>svn mv trunk subproject
A subproject\trunk
D trunk
D trunk\testfile.txt
C:\hgtest\svncheckout>svn ci -m "Moved trunk to subproject/trunk"
Adding subproject
Adding subproject\trunk
Deleting trunk
Committed revision 2.
C:\hgtest\svncheckout>echo ". Adding some text to distinguish the subproject/trunk version of this file" >> subproject\trunk\testfile.txt
C:\hgtest\svncheckout>svn ci -m "Final version of testfile.txt"

Solution
Yes, but it'll be a manual process. You'll need to find the high water mark revision for each branch and record it in the metadata files (the names of which escape me at the moment). At that point, things should mostly work.
Note: this is a theory. I have high confidence that it should work based on my memory of the code, but I've never tested it.
OTHER TIPS
Basically, I'm wondering if it's possible to tell hgsubversion to use a certain svn revision as its reference point, only attempting to sync up the histories from that point forward?
If I understood you correctly, you wanted --startrev option for clone command. From hg help subversion
Sometimes, past repository history is of little or no interest, and all one wants is to start from today and work forward. Using "--startrev HEAD" causes the initial clone to only convert the latest revision; later pulls will convert all subsequent revisions. Please note that this only works for single-directory clones
