[Zope-Coders] Unit testing issues

[Tres Seaver]

Interestingly, when trying to fix the problem reported by Shane's
tinderbox (one I presume I introduced yesterday), I reran the tests,
and found that the OFS tests all pass on my sandbox.  I fetched a fresh
checkout of Zope, and voila, it is broken.  The two checkouts differ
only trivially;  can anyone eyeball soemthing significant here?

 [/home/tseaver/projects/Zope-fresh] $ cvs -q up -AdP
 [/home/tseaver/projects/Zope-fresh] $ cd ../Zope-head
 [/home/tseaver/projects/Zope-head] $ cvs -q up -AdP
 [/home/tseaver/projects/Zope-head] $ cd ..
 [/home/tseaver/projects] $ diff -r -u -x "*.so" -x "*.pyc" -x CVS \
                              Zope-head Zope-fresh
 diff -r -u -x *.so -x *.pyc -x CVS Zope-head/stop Zope-fresh/stop

I'm totally stuck trying to figure out how running the tests from two
directories which differ only by that much should have such different
results.  I have deleted and rebuilt all "*.pyc", ".o", and "*.so"
files in both trees, BTW.

I also have a separate problem:  in my sandbox, three ZEO tests blow up:

Jeremy, do you have a clue where the ZEO errors are coming from?
This is with Python 2.1.1, against the head of the 'zeo-1_0-branch'.
