Hm. In my version of these tests, I only have one regression from the
old combo (in the pathological tags test, t9602).  You're seeing more
breakage than that, obviously.

That suggests that something in your test setup has gone bad and is
introducing spurious errors. Which would be consistent with the above.

That's possible, but seems unlikely.  Because the new cvsimport is
such a thin wrapper around the conversion engine, bugs in it should
lead to obvious crashes or failure to run the engine rather than the 
sort of conversion error the t960* tests are designed to check.  Really
all it does is assemble options to pass to the conversion engines.

My test strategy is aimed at the engine, not the wrapper. I took the
repos from t960*  and wrote a small Python framework to check the same 
assertions as the git-tree tests do, but using the engine.  For example,
here's how my t9602 looks:

import os, cvspstest

cc = cvspstest.ConvertComparison("t9602", "module")
cc.cmp_branch_tree("test of branch", "master", True)
cc.cmp_branch_tree("test of branch", "vendorbranch", True)
cc.cmp_branch_tree("test of branch", "B_FROM_INITIALS", False)
cc.cmp_branch_tree("test of branch", "B_FROM_INITIALS_BUT_ONE", False)
cc.cmp_branch_tree("test of branch", "B_MIXED", False)
cc.cmp_branch_tree("test of branch", "B_SPLIT", True)
cc.cmp_branch_tree("test of tag", "vendortag", False)
# This is the only test new cvsps fails that old git-cvsimport passed.
cc.cmp_branch_tree("test of tag", "T_ALL_INITIAL_FILES", True)
cc.cmp_branch_tree("test of tag", "T_ALL_INITIAL_FILES_BUT_ONE", False)
cc.cmp_branch_tree("test of tag", "T_MIXED", False)

Probably.  But I don't think you should keep these tests in the git tree.
That wasn't a great idea even when you were supporting just one engine;
with two (and soon three) it's going to be just silly.  Let sanity-checking
the engines be *my* problem, since I have to do it anyway.

(I'm working towards the generalized test suite as fast as I can.  First
results probably in four days or so.)

Yes, that's just what -a is supposed to do.  But is should be
irrelevant for testing - in the test framework CVS is running locally, 
so there's no network lag.

That would be bad, IMO.  I'll put backporting to 2.6 high on my to-do list.
