Kevan Carstensen [Sat, 20 Feb 2010 21:07:13 +0000 (13:07 -0800)]
Change OphandleTable to use a deterministic clock, so we can test it

To test the changes for #577, we need a deterministic way to simulate
the passage of long periods of time. twisted.internet.task.Clock seems,
from my Googling, to be the way to go for this functionality. I changed
a few things so that OphandleTable would use twisted.internet.task.Clock
when testing:

  * WebishServer.__init___ now takes an optional 'clock' parameter,
  * which it passes to the root.Root instance it creates.
  * root.Root.__init__ now takes an optional 'clock' parameter, which it
    passes to the OphandleTable.__init__ method.
  * OphandleTable.__init__ now takes an optional 'clock' parameter. If
    it is provided, and it isn't None, its callLater method will be used
    to schedule ophandle expirations (as opposed to using
    reactor.callLater, which is what OphandleTable does normally).
  * The WebMixin object in test_web.py now sets a self.clock parameter,
    which is a twisted.internet.task.Clock that it feeds to the
    WebishServer it creates.

Tests using the WebMixin can control the passage of time in
OphandleTable by accessing self.clock.

checker: don't let failures in add-lease affect checker results. Closes #875.

Mutable servermap updates and the immutable checker, when run with
add_lease=True, send both the do-you-have-block and add-lease commands in
parallel, to avoid an extra round trip time. Many older servers have problems
with add-lease and raise various exceptions, which don't generally matter.
The client-side code was catching+ignoring some of them, but unrecognized
exceptions were passed through to the DYHB code, concealing the DYHB results
from the checker, making it think the server had no shares.

The fix is to separate the code paths. Both commands are sent at the same
time, but the errback path from add-lease is handled separately. Known
exceptions are ignored, the others (both unknown-remote and all-local) are
logged (log.WEIRD, which will trigger an Incident), but neither will affect
the DYHB results.

The add-lease message is sent first, and we know that the server handles them
synchronously. So when the checker is done, we can be sure that all the
add-lease messages have been retired. This makes life easier for unit tests.
