[IPython-dev] Test failures and errors in trunk

[Brian Granger]

OK, I found the commit that introduced the error.  It first appears in
this revision:

http://bazaar.launchpad.net/~fdo.perez/ipython/trunk-dev/revision/1155

The previous revision passes all tests just fine.  You can get the
problematic revision by doing:

bzr branch lp:~fdo.perez/ipython/trunk-dev -r 1155

It is worth checking that the previous revision is OK on your system as well.

But, this one could be a challenge to figure out.  In this revision,
you were only touching non-twisted parts of the test suite - basically
getting the ipdoctest stuff working right.  Hopefully between the two
of us we can figure this out.  I know the Twisted stuff, you know the
ip testing stuff.

I am going to switch gears to help Ondrej with some things.  If you
end up looking at this and have questions on the Twisted side of
things let me know.

Looks pretty similar, but I think it is somewhat different.  I have
never seen the double call to reactor.run() before.

Yes, this seems like it is pretty important.  I ended up doing that
when we did the last release and it really helped.

Cheers,
