twisted.web.html.escape was used to produce html-encoded string (to then look
it up in "value" attribute), but behavior of that function has changed between
Twisted 12.2.0 (simple custom implementation) and 12.3.0 (imported from stdlib
cgi module).
This also simplifies how case-insensitivity is handled, and fixes a corner case
where the wrong exception was raised when the size ends in "BB".

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.

This prints out which things are different when two sets are expected to be the
same. This was useful to me when debugging the code under test. Hm, this
pattern might be more generally useful...
This probably only works on Linux. It uses sudo to mount and unmount the tmpfs,
which may prompt for a password. refs #20

The wait_for_connections() method, which is used at the start of
test_system to make sure that all the clients are connected to all the
servers, did not also wait for clients to be connected to their Helpers.
Every once in a while, the helper connection would take a bit longer,
and then
test_system.SystemTest.test_filesystem._test_web._got_welcome_helper
would fail, because we'd check for a helper connection before it was
ready.
The fix is to modify wait_for_connections's polling predicate to look
for helper connections (if configured) as well as the regular
introducer- and server- connections.
Tested by temporarily adding a large (30s) delay to the connectTo() call
in Uploader.startService, simulating a long helper
connection-establishment delay. This makes the test fail consistently.
Then I fixed wait_for_connections(), and the test passed (slowly). Then
I removed the delay.
Closes#1467
This makes it easy to distinguish between old V1-Introducer
nodes (identified by their Foolscap TubID) and new V2 nodes (identified
by their ed25519 pubkey).
This fixes a few places where we used to display a tubid even if we had
a pubkey, making it hard to visually correlate servers in two different
displays. It also cleans up the way we pass serverids to the JS-based
download timeline.
The "introweb" subscribed-clients list still shows tubids.
The _upload_resumable() test interrupts a Helper upload partway
through (by shutting down the Helper), then restarts the Helper and
resumes the upload. The control flow is kind of tricky: to do anything
"partway through" requires adding a hook to the Uploadable. The previous
flow depended upon a (fragile) call to self.stall(), which waits a fixed
number of seconds.
This removes one of those stall() calls (the remainder is in
test/common.py and I'll try removing it in a subsequent revision). It
also removes some now-redundant wait_for_connections() calls, since
bounce_client() doesn't fire its Deferred until the client has finished
coming back up (and uses wait_for_connections() internally to do so).
DeepResultsBase also has a get_corrupt_shares(), and it is populated
from CheckResults.get_corrupt_shares(). It has been updated too, along
with get_remaining_corrupt_shares().
Remove temporary get_new_corrupt_shares() and
get_new_incompatible_shares().
This changes all code which feeds CheckResults(sharemap=) to provide
IServer instances, but CheckResults converts these to old-style
serverids during output, so downstream code doesn't have to change yet.
It adds a temporary get_new_sharemap(), which *does* return IServer
instances, so the immutable repairer can build new CheckResults from an
old one. This will go away when get_sharemap() is updated to return
IServer (and downstream code is updated too).
i.e. change set_data() to accept lots of parameters, instead of taking
a single dictionary with lots of keys. Also Convert all CheckResults
creators to use it.
The goal is to make CheckResults more strongly typed, and remove the
ambiguous ".data" field in favor of a bunch of specific counters and
sharelists, so I can changes .sharemap and .servermap to use IServer
instances instead of string serverids. By cleaning this up first, I hope
to get that task done with less debugging.
