 A candidate patch for #1429 has a bug when it is using FilePath.is_dir() to detect whether the configured local dir exists and is a directory. FilePath.is_dir() raises exception, instead of returning False, if the thing doesn't exist. This test is to make sure that DropUploader.__init__ raise different exceptions for those two cases.

 format. In particular, we define read and write proxy objects used by
 retrieval, publishing, and other code to write and read the MDMF share
 format. We create equivalent proxies for SDMF objects so that these
 objects can be suitably general.

 of using an extension of the mock.patch() function from the mock library) and

warner@lothar.com**20110227011153
 Ignore-this: bcd62232c9159371ae8a16ff63d22c1b
 
 When blocks terminate (either COMPLETE or CORRUPT/DEAD/BADSEGNUM), the
 _shares_from_server dict was being popped incorrectly (using shnum as the
 index instead of serverid). I'm still thinking through the consequences of
 this bug. It was probably benign and really hard to detect. I think it would
 cause us to incorrectly believe that we're pulling too many shares from a
 server, and thus prefer a different server rather than asking for a second
 share from the first server. The diversity code is intended to spread out the
 number of shares simultaneously being requested from each server, but with
 this bug, it might be spreading out the total number of shares requested at
 all, not just simultaneously. (note that SegmentFetcher is scoped to a single
 segment, so the effect doesn't last very long).

 The effects outside these three files should be minimal: some exception

 Pass around IServer instance instead of (peerid, rref) tuple. Replace
 "descriptor" with "server". Other replacements:
 
  get_all_servers -> get_connected_servers/get_known_servers
  get_servers_for_index -> get_servers_for_psi (now returns IServers)
 
 This change still needs to be pushed further down: lots of code is now
 getting the IServer and then distributing (peerid, rref) internally.
 Instead, it ought to distribute the IServer internally and delay
 extracting a serverid or rref until the last moment.
 
 no_network.py was updated to retain parallelism.
