24812905a1 test_introducer.SystemTest: fix race condition
SystemTest has a couple of different phases, separated by a poller which
waits for everything to be idle (all messages delivered, none in flight). It
does this by watching some internal "_debug_outstanding" counters in the
server and in each client, and waiting for them to hit zero.

Just before the last phase, we replace the server with a new one (to make
sure clients re-send their messages properly). Unfortunately, the polling
function closed over the variable holding the original server, and didn't see
the replacement. It kept polling the old server, and failed to notice the
outstanding messages for the new server. The last phase of the test (check3)
was started too early, which failed (since some messages had not yet been
delivered), and then exploded in a flurry of dirty-reactor errors (because
some messages were delivered after test shutdown).

This replaces the closed-over-variable with a "self.the_introducer", which
seems to fix the race.

One additional place to look at in the future: the client
announcement-receive path (remote_announce) uses an eventually(). If the
message has been received and the eventual-send posted (but not yet executed)
when the poller sees it, the poller might erroneously conclude that the
client is idle and cause the same problem as above. To fix this, the poller
(probably all pollers) could be enhanced to do a flushEventualQueue before
querying the are-we-done-yet predicate function.

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.

890449801e IServer.get_name(): remove v0- prefix from displayed server names
Don't remove the prefix if it isn't there: that avoids the need to fix tests
which use a bogus key (usually all-zeros).

bc21726dfd new introducer: signed extensible dictionary-based messages! refs #466
This introduces new client and server halves to the Introducer (renaming the
old one with a _V1 suffix). Both have fallbacks to accomodate talking to a
different version: the publishing client switches on whether the server's
.get_version() advertises V2 support, the server switches on which
subscription method was invoked by the subscribing client.

The V2 protocol sends a three-tuple of (serialized announcement dictionary,
signature, pubkey) for each announcement. The V2 server dispatches messages
to subscribers according to the service-name, and throws errors for invalid
signatures, but does not otherwise examine the messages. The V2 receiver's
subscription callback will receive a (serverid, ann_dict) pair. The
'serverid' will be equal to the pubkey if all of the following are true:

  the originating client is V2, and was told a privkey to use
  the announcement went through a V2 server
  the signature is valid

If not, 'serverid' will be equal to the tubid portion of the announced FURL,
as was the case for V1 receivers.

Servers will create a keypair if one does not exist yet, stored in
private/server.privkey .

The signed announcement dictionary puts the server FURL in a key named
"anonymous-storage-FURL", which anticipates upcoming Accounting-related
changes in the server advertisements. It also provides a key named
"permutation-seed-base32" to tell clients what permutation seed to use. This
is computed at startup, using tubid if there are existing shares, otherwise
the pubkey, to retain share-order compatibility for existing servers.

ec7bc05c04 tahoe.css: fix #section typo, update welcome.xhtml to match
The "#section" declaration (which matches id="section") should have been
".section" (which matches class="section").

The welcome page has a feature that I actually liked: the little "This
Client" sidebar sits just to the right of the start of the Controls block.
Fixing .section broke that (the clear:both introduces a gap, forcing the
Controls block to start strictly below the bottom of the This Client block).
So I also removed class="section" from the Controls block to allow them to
share the horizontal space again.

1469b1b9f9 Ensure that verification proceeds and stops when appropriate.
The removed assertions are appropriate for a download that seeks to
return plaintext to a caller; if we don't have at least k active remote
shares, then we can't hope to do that. They're not appropriate for a
verification operation; a user can try to verify a file that has fewer
than k shares available, so that shouldn't be treated as an error.
Instead, we proceed with fewer than k shares, and ensure that we
terminate the download if we have no shares at all and we're verifying.

e29323f68f mutable publish: track multiple servers-per-share. Fixes some of #1628.
The remaining work is to write additional tests.

src/allmydata/test/no_network.py:

 This supports tests in which servers leave the grid only to return with
 their shares intact at a later time.

src/allmydata/test/test_mutable.py:

 The UCWEs in the incident reports associated with #1628 all seem to be
 associated with shares that the servermap knows about, but which aren't
 accounted for during the publish process for whatever reason. Specifically,
 it looks like the publisher is only capable of keeping track of a single
 storage server for a given share. This makes the repair process worse than
 it was pre-MDMF at updating all of the shares of a particular file to the
 newest version, and can also cause spurious UCWEs. This test simulates such
 a layout and fails if an UCWE is thrown. We need to write another test to
 ensure that all copies of a share are updated to the latest version (or
 alter this test to do that), so that the test suite doesn't pass unless both
 regressions are fixed.

 We want the publisher to follow the existing share placement when uploading
 a new version of a mutable file, and we don't want this test to pass unless
 it does.

src/allmydata/mutable/publish.py:

 Before this commit, the publisher only kept track of a single writer for
 each share. This is insufficient to handle updates in which a single share
 may live on multiple servers. In the best case, an update will only update
 one of the existing shares instead of all of them. In some cases, the update
 will encounter the existing shares when publishing some other share,
 interpret it as a sign of an uncoordinated update, and fail. Keeping track
 of all of the writers helps ensure that all existing shares are updated, and
 helps avoid spurious uncoordinated write errors.

7d5ca407a1 setup.py: get version from git or darcs
This replaces the setup.cfg aliases that run "darcsver" before each major
command with the new "update_version". update_version is defined in setup.py,
and tries to get a version string from either darcs or git (or leaves the
existing _version.py alone if neither VC metadata is available).

Also clean up a tiny typo in verlib.py that messed up syntax hilighting.

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):

633641174a mutable/retrieve: don't write() after we've been pauseProducer'ed
This fixes a test failure found against current Twisted trunk in
test_mutable.Filenode.test_retrieve_producer_mdmf (when it uses
PausingAndStoppingConsumer). There must be some sort of race: I could
make it fail against Twisted-11.0 if I just increased the 0.5s delay in
test_download.PausingAndStoppingConsumer to about 0.6s, and could make
Twisted-trunk pass by reducing it to about 0.3s .

I fixed the test (as opposed to the bug) by replacing the delay with a
simple reliable eventually(), and adding extra asserts to fail the test
if the consumer's write() method is called while the producer is
supposed to be paused

The bug itself was that mutable.retrieve.Retrieve wasn't checking the
"stopped" flag after resuming from a pause, and thus delivered one
segment to a consumer that wasn't expecting it. I split out
stopped-flag-checking to separate function, which is now called
immediately after _check_for_paused(). I also cleaned up some Deferred
usage and whitespace.
