Without these, clients with a non-empty connections.yaml would crash as
they start up. It's safe to say we need some tests for this :-).
pyflakes catches all of these, but it got accidentally disabled
recently, so travis wasn't running it. I'll fix that in the next commit.
This has worked so far because everything waited for the Tub to be
ready. We'll soon be making Tub setup synchronous, so we won't have to
wait anymore, so the order will matter.
this includes a squash merge of dca1de6856 which
was previously seen in pull request #128, as well as daira's suggested changes
from pull request #204.
This tests ftpd, but not sftpd. Doing this sort of test on sftpd
requires the creation of a valid pubkey/privkey file pair, which is more
work than I want to do right now.
init_ftp/init_sftp were changed to interpret the configured
accounts.file as relative to the node's basedir, with
abspath_expanduser_unicode(accountfile, base=self.basedir).
This would happen naturally in a real node, since it os.chdir()s
to the basedir before doing anything. But tests don't do that.

For a brief while (in between releases 1.9 and 1.10, specifically from
revision bc21726 on 12-Mar-2012, until bf416af on 10-Jun-2012), the new
introducer code stored its node key in NODEDIR/private/server.privkey .
After that point, it was updated to store this key in
NODEDIR/private/node.privkey instead. Fallback code was added to read
from the old location if present (so that folks using development
versions could keep their node keys after the bf416af change).
This patch removes the fallback code. If you have a node which was run
under a version of Tahoe within this range, you need to manually update
your node by running:
mv NODEDIR/private/server.privkey NODEDIR/private/node.privkey
and then restart the node. If you accidentally start an older node with
code after this patch, it will create a new key (and other peers will
think a new server has appeared). You can either stick with the new key,
or use the command above to switch back to the old key.
See docs/nodekeys.rst (not yet written) for details about the node key
and how it is used.
This should now fail quickly (during "tahoe start"). Previously this
would silently treat an unparseable size as "0", and the only way to
discover that it had had a problem would be to look at the foolscap log,
or examine the storage-service web page for the unexpected "Reserved
Size" number.
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).
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)
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.
* fix tahoe.cfg control of default mutable type
* tolerate arbitrary case in [client]mutable.format value
* small docs improvements
* use get_mutable_type() as a format-is-mutable predicate
* tighten up error message
* fix CLI commands (put, mkdir) to send format=, not mutable-type=
* fix tests
* test_cli: fix tests that observe t=json output, don't ignore failures in
'tahoe put'
* fix handling of version= to make it easier to use the default
* interpret ?mutable=true&format=MDMF as MDMF, not SDMF
This consistently records all immutable uploads in the Recent Uploads And
Downloads page, regardless of code path. Previously, certain webapi upload
operations (like PUT /uri/$DIRCAP/newchildname) failed to pass the History
object and were left out.
I rerecorded this patch, originally by David-Sarah, to use "darcs replace" instead of editing to do the renames. This uncovered one missed rename in Client.init_drop_uploader. (Which also means that code isn't exercised by the current unit tests.)
refs #1429
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.
