[Zope3-dev] ZEO test failing under Cygwin

[Godefroid Chapelle]

It's a long time that I did not pursue the research to make tests run fully 
on Cygwin.


if I use the following code in /src/zodb/zeo/zrpc/client.py,
with two supplementary lines

             try:
                 r, w, x = select.select([], connecting, connecting, 1.0)
                 log.info("CT: select() %d, %d, %d" % tuple(map(len, (r,w,x))))
             except select.error, msg:
                 # XXX Is error the right level?
                 log.error("CT: select failed; msg=%s", msg)
                 continue
             # Exceptable wrappers are in trouble; close these suckers
             for wrap in x:
                 if wrap in w:                             #added by GC 
following Tim advice
                     w.remove(wrap)                   #added by GC 
following Tim advice
                 log.info("CT: closing troubled socket %s", str(wrap.addr))
                 del wrappers[wrap]
                 wrap.close()



all but 1 zodb/zeo tests pass as you can see hereunder :

As the z3 community is getting bigger, some people with windows only like 
me begin to join.
It would help a lot to have the full test suite running under Cygwin as 
this would allow us
to say them to use this convenient setup (cfr for example, make clean, 
make, make test).
