3e26c78ee3 introducer.client: use integer seqnums, not time-based. Closes #1767. 
This stores the sequence number in BASEDIR/announcement-seqnum, and
increments it each time any service is published (every service
announcement is regenerated with the new sequence number). As everyone
knows, time is an illusion, and occasionally goes backwards, so a
counter is generally safer (and reveals less information about the
node).

Later, we'll improve the introducer client to tolerate rollbacks (where,
perhaps due to a VM being restarted from an earlier checkpoint, the
stored sequence number reverts to an earlier version).

ff64a0fef5 fileutil.write: accept mode=, and use it in Node.write_config 
I want mode="w" (i.e. text, with newline conversion) for code that
writes newline-terminated strings (which should also be human readable)
to files. I like to use things like "cat .tahoe/permutation-seed"
without seeing the seed jammed together with the next command prompt.

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.

69bd49fc57 _auto_deps: bump foolscap to >=0.6.3 to tolerate twisted-12.0.0 
The current Twisted release is 12.1.0, which (like 12.0.0 before it)
isn't compatible with foolscap-0.6.2 and earlier. We previously required
foolscap>=0.6.1, since that's all we actually need from foolscap itself.
_auto_deps specifies twisted>=11.0.0, so any system that can't meet that
will install the current Twisted (12.1.0), which will give them
something incompatible with foolscap-0.6.1 and 0.6.2 .

If we're limited to setuptools's declarative constraint language (and
can't have a function which evaluates the available dependency versions
and gives recommendations on which to change), then the only safe
approach is to make sure that any acceptable Foolscap version will be
compatible with all acceptable Twisted versions. So, bump the foolscap
dependency to >=0.6.3, which covers all currently-known
incompatibilities.

b2dcbbb62d test/common.py: fix race condition waiting for the helper connection 
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.

ef2db56104 introweb: the Subscribed Clients list shows tubids, not serverids 
Improve the column headers to make it clear that this list shows Tub
IDs. (we can't show pubkey-based serverids because clients don't give
those to us: only servers provide pubkeys). This should be the only
place in the whole webapi that shows TubIDs for modern (V2-introducer)
nodes.

c073565ecc Display serverids consistently as 8-char pubkey, or 6-char tubid. 
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.

5e432b12a1 test_system.py: clean up control flow, reduce use of stall() 
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).

bf416af49e client.py: rename "server key" to "node key", use old name if present 
This prepares for invitation-based reciprocal-permission Accounting. In
the scheme I'm developing, nodes publish "I accept shares from Y"
messages, which are assembled into a graph, and server will accept
shares from any client node reachable in this graph. For this to work,
the serverX->clientY edge must be connectable to the serverY->clientZ
edge, which means "clientY" and "serverY" must be connected. If clientY
and serverY are two distinct keys, they must be cross-signed. Life is
easier if there's just one key "Y", rather than distinct client- and
server- keys. Calling this one key "server.privkey" would be confusing.
"node.privkey" and "node.pubkey" makes more sense.

One-server-per-node is a pretty easy restriction. Originally I was
thinking that the client.key should be provided in each webapi call,
just like a filecap is, making a single node useable by multiple users
(Accounting principals), and not providing any ambient storage
authority. But I've been unable to think of a comfortable WUI for
that (at least without requiring javascript), nor a friendly way to
transfer account authority (e.g. writecaps that include storage
authority). So I'm more willing to have one-client-per-node these days.

(and note that this rename doesn't seriously preclude
many-clients-per-node or zero-clients-per-node anyways, it just makes
one-client-per-node less awkward)

a4c95609c7 CheckResults: pass IServer to sharemap=, but get_sharemap() returns serverids 
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).

bfee999e20 test_web.py: fix memory leak when run with --until-failure 
The Fake*Node classes in test/common.py were accumulating share data in
a class-level dictionary, which persisted from one test run to the next.
As a result, running test_web.py over and over (with trial's
--until-failure feature) made this dictionary grow without bound,
eventually running out of memory.

This fix moves that dictionary into the FakeClient built fresh for each
test, so it doesn't build up. It does the same thing for "file_types",
which was much smaller but still lived at the class level.

Closes #1729

843739486a UploadResults: store IServers internally, but still return serverids 
This stores IDisplayableServer-providing instances (StubServers or
NativeStorageServers) in the .servermap and .sharemap dictionaries. But
get_servermap()/get_sharemap() still return data structures with
serverids, not IServers, by translating their data on the way out. This
lets us put off changing the callers for a little bit longer.

97a1eb6ebf split IDisplayableServer from IServer, add sb.get_stub_server() 
IDisplayableServer includes just enough functionality to call
.get_name() and friends, which is all that the UploadResults really
need. IServer is a superset that includes actual share-manipulation
methods. StubServer instances provide only IDisplayableServer, while
actual NativeStorageServer instances provide the full IServer interface.

When the Helper sends a serverid (so we know what to call the server but
nothing else about it, and have no corresponding NativeStorageServer
object to reference), but we want to store an IDisplayableServer in the
UploadResults, we create a synthetic StubServer "server" and store that
instead.

e60982c851 helper: remove timings["existence_check"], aka "Already-In-Grid Check" 
This measured how long the Helper took to do a filecheck before asking
for ciphertext. The "Contacting Helper" report includes both
existence_check and the client-helper RTT.

For non-overlapping uploads, it was being returned correctly. But when
multiple upload requests overlapped, and the file was not already in the
grid, the filecheck would only run once, and its existence_check time
would be reported for all uploaders (even if they didn't have to wait
for that time). Cleaning that up proved too difficult: the only correct
place to report this time is from the initial remote_upload_chk() call,
but the return value of that is too constrained to accomodate it in the
needs-upload case.

So I'm removing it altogether. Eventually I plan to add a proper
events/times field and record more data, including this check, in a form
that can be drawn on a nice zoomable timeline view.

Old clients talking to a new Helper (which doesn't supply the value)
will tolerate the loss (they'll just display an empty field on the web
view).

9acf5beebd immutable repairer: populate servers-responding properly 
If a server did not respond to the pre-repair filecheck, but did respond
to the repair, that server was not correctly added to the
RepairResults.data["servers-responding"] list. (This resulted from a
buggy usage of DictOfSets.union() in filenode.py).

In addition, servers to which filecheck queries were sent, but did not
respond, were incorrectly added to the servers-responding list
anyawys. (This resulted from code in the checker.py not paying attention
to the 'responded' flag).

The first bug was neatly masked by the second: it's pretty rare to have
a server suddenly start responding in the one-second window between a
filecheck and a subsequent repair, and if the server was around for the
filecheck, you'd never notice the problem. I only spotted the smelly
code while I was changing it for IServer cleanup purposes.

I added coverage to test_repairer.py for this. Trying to get that test
to fail before fixing the first bug is what led me to discover the
second bug. I also had to update test_corrupt_file_verno, since it was
incorrectly asserting that 10 servers responded, when in fact one of
them throws an error (but the second bug was causing it to be reported
anyways).

Brian Warner
c4d7b7b109 write node.url and portnum files atomically, to fix race in test_runner 
Previously, test_runner sometimes fails because the _node_has_started()
poller fires after the portnum file has been opened, but before it has
actually been filled, allowing the test process to observe an empty file,
which flunks the test.

This adds a new fileutil.write_atomically() function (using the usual
write-to-.tmp-then-rename approach), and uses it for both node.url and
client.port . These files are written a bit before the node is really up and
running, but they're late enough for test_runner's purposes, which is to know
when it's safe to read client.port and use 'tahoe restart' (and therefore
SIGINT) to restart the node.

The current node/client code doesn't offer any better "are you really done
with startup" indicator.. the ideal approach would be to either watch the
logfile, or connect to its flogport, but both are a hassle. Changing the node
to write out a new "all done" file would be intrusive for regular
operations.

518ef25bdb Add ETags for immutable directories 
Like immutable files, the ETag is based on the storage index. However, since
a directory is a special interpretation of a file, it is distinguished from
the file by prepending "DIR:" onto the start of the ETag, and adding
-representation on the end (where -representation is the ?t= argument, json,
info, etc).

It also checks the return of setETag and avoids generating a representation
if the client already has it.

Instead of poking around in the introducer's internals, now the web-status
renderers get clean AnnouncementDescriptor and SubscriberDescriptor

abstraction boundary for future improvements.

The specific #1721 bug was that old (V1) subscribers were handled by
wrapping their RemoteReference in a special WrapV1SubscriberInV2Interface
object, but the web-status display was trying to peek inside the object to
learn what host+port it was associated with, and the wrapper did not proxy
those extra attributes.

A test was added to test_introducer to make sure the introweb page renders
properly and at least contains the nicknames of both the V1 and V2 clients.

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.

of serverids. That will need some more work, since it might change the Helper
interface.

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.

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.

0716c496c8 MDMF: remove extension fields from caps, tolerate arbitrary ones. Fixes #1526 
The filecaps used to be produced with hints for 'k' and segsize, but they
weren't actually used, and doing so had the potential to limit how we change
those filecaps in the future. Also the parsing code had some problems dealing
with other numbers of extensions. Removing the existing fields and making the
parser tolerate (and ignore) extra ones makes MDMF more future-proof.
