[Change OphandleTable to use a deterministic clock, so we can test it
Kevan Carstensen <kevan@isnotajoke.com>**20100220210713
 Ignore-this: a7437f4eda359bdfa243bd534f23bf52
 
 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.

 This can be useful if one of the ones that he has already begun downloading fails. See #287 for discussion. This fixes part of #287 which part was a regression caused by #928, namely this fixes fail-over in case a share is corrupted (or the server returns an error or disconnects). This does not fix the related issue mentioned in #287 if a server hangs and doesn't reply to requests for blocks.

[immutable: download from the first servers which provide at least K buckets instead of waiting for all servers to reply
zooko@zooko.com**20100127233417
 Ignore-this: c855355a40d96827e1d0c469a8d8ab3f
 This should put an end to the phenomenon I've been seeing that a single hung server can cause all downloads on a grid to hang.  Also it should speed up all downloads by (a) not-waiting for responses to queries that it doesn't need, and (b) downloading shares from the servers which answered the initial query the fastest.
 Also, do not count how many buckets you've gotten when deciding whether the download has enough shares or not -- instead count how many buckets to *unique* shares that you've gotten.  This appears to improve a slightly weird behavior in the current download code in which receiving >= K different buckets all to the same sharenumber would make it think it had enough to download the file when in fact it hadn't.
 This patch needs tests before it is actually ready for trunk.

 Ignore-this: ef1a367b93e4d01298c2b1e6ca59c492
 
 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.

 The webapi has been looking for an Accept header since 1.4.0, but it treats a
 missing header as equal to */* (to honor RFC2616). This change finally
 modifies our CLI tools to ask for "text/plain, application/octet-stream",
 which seems roughly correct (we either want a plain-text traceback or error
 message, or an uninterpreted chunk of binary data to save to disk). Some day
 we'll figure out how JSON fits into this scheme.

 This is safer: in the earlier API, an old webapi server would silently ignore
 the initial children, and clients trying to set them would have to fetch the
 newly-created directory to discover the incompatibility. In the new API,
 clients using t=mkdir-with-children against an old webapi server will get a

 We need to carefully document the licence of figleaf in order to get Tahoe-LAFS into Ubuntu Karmic Koala.  However, figleaf isn't really a part of Tahoe-LAFS per se -- this is just a "convenience copy" of a development tool.  The quickest way to make Tahoe-LAFS acceptable for Karmic then, is to remove figleaf from the Tahoe-LAFS tarball itself.  People who want to run figleaf on Tahoe-LAFS (as everyone should want) can install figleaf themselves.  I haven't tested this -- there may be incompatibilities between upstream figleaf and the copy that we had here...
