db12f1cffb Adds _servers_with_shares to ServermapUpdater
When calculating the query boundary for updates to mutable files,
instead of using servers that used to have shares, use servers we
have added to the servermap. This way the querying process won't finish
until we have finished interacting with the servers that have shares.

This fixes the race condition which sometimes caused the querying process
to finish before the updater was done talking to servers with shares.

4751a46840 ServerMap.copy(): deepcopy .update_data too. Closes #1785.
This was apparently unused, but good to copy for completeness. Tests
pass with and without the change.

4563ba456b Remove ResponseCache in favor of MDMFSlotReadProxy's cache. closes #1240.
This contains several merged patches. Individual messages follow, latest first:

* Fix a warning from check-miscaptures.
* In retrieve.py, explicitly test whether a key is in self.servermap.proxies
  rather than catching KeyError.
* Added a new comment to the MDMF version of the test I removed, explaining
  the removal of the SDMF version.
* Removed test_corrupt_all_block_hash_tree_late, since the entire block_hash_tree
  is cached in the servermap for an SDMF file.
* Fixed several tests that require files larger than the servermap cache.
* Remove unused test_response_cache_memory_leak().
* Exercise the cache.
* Test infrastructure for counting cache misses on MDMF files.
* Removed the ResponseCache. Instead, the MDMFSlotReadProxy initialized
  by ServerMap is kept around so Retrieve can access it. The ReadProxy
  has a cache of the first 1000 bytes initially read from each share by
  the ServerMap. We're able to satisfy a number of requests out of this
  cache, so roundtrips are reduced from 84 to 60 in test_deepcheck_mdmf.
  There is still some mystery about under what conditions the cache has
  fewer than 1000 bytes. Also this breaks some existing unit tests that
  depend on the inner behavior of ResponseCache.
* The servermap.proxies (a cache of SlotReadProxies) is now keyed
  by (verinfo,serverid,shnum) rather than just (serverid,shnum)
* Minor cosmetic changes
* Added a test failure if the number of cache misses is too high.

5bae4a1bd2 Mutable repair: use new MODE_REPAIR to query all servers *and* get privkey
This fixes bug #1689. Repair was using MODE_READ to build the servermap,
which doesn't try hard enough to grab the privkey, and also doesn't guarantee
sending queries to all servers. This patch adds a new MODE_REPAIR which does
both, and does a separate, distinct mapupdate to start wth repair cycle,
instead of relying upon the (MODE_CHECK) mapupdate leftover from the
filecheck that triggered the repair.

a56e639346 Fix mutable status (mapupdate/retrieve/publish) to use serverids, not tubids
This still leaves immutable-publish results incorrectly using tubids instead
of serverids. That will need some more work, since it might change the Helper
interface.

5bf1ffbc87 IServer refactoring: pass IServer instances around, instead of peerids
refs #1363

This collapses 88 small incremental changes (each of which passes all tests)
into one big patch. The development process for the long path started with
adding some temporary scaffolding, changing one method at a time, then
removing the scaffolding. The individual pieces are as follows, in reverse
chronological order (the first patch is at the end of this comment):

2b4f2b7fa3 MDMFSlotReadProxy: remove the queue
This is a neat trick to reduce Foolscap overhead, but the need for an
explicit flush() complicates the Retrieve path and makes it prone to
lost-progress bugs.

Also change test_mutable.FakeStorageServer to tolerate multiple reads of the
same share in a row, a limitation exposed by turning off the queue.

ffd296fc5a Refactor StorageFarmBroker handling of servers
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.

794e32738f 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.

0d5dc51617 Overhaul IFilesystemNode handling, to simplify tests and use POLA internally.
* stop using IURI as an adapter
* pass cap strings around instead of URI instances
* move filenode/dirnode creation duties from Client to new NodeMaker class
* move other Client duties to KeyGenerator, SecretHolder, History classes
* stop passing Client reference to dirnode/filenode constructors
  - pass less-powerful references instead, like StorageBroker or Uploader
* always create DirectoryNodes by wrapping a filenode (mutable for now)
* remove some specialized mock classes from unit tests

Detailed list of changes (done one at a time, then merged together)

always pass a string to create_node_from_uri(), not an IURI instance
always pass a string to IFilesystemNode constructors, not an IURI instance
stop using IURI() as an adapter, switch on cap prefix in create_node_from_uri()

mutable.FileNode: removed unused indirection to checker classes

client.py: move RSA key generation into a separate class, so it can be passed to the nodemaker
move create_mutable_file() into NodeMaker
test_dirnode.py: stop using FakeClient mockups, use NoNetworkGrid instead. This simplifies the code, but takes longer to run (17s instead of 6s). This should come down later when other cleanups make it possible to use simpler (non-RSA) fake mutable files for dirnode tests.
