This shows current-connection info, and provides per-hint status details in a
tooltip.
The "Connection" section no longer shows seconds-since-loss when the server
was not connected (previously it showed seconds-since-connect when connected,
and flipped to seconds-since-loss when disconnected). We already have the
"Last RX" column, which is arguably more meaningful (and I can't think of a
good case when these would differ), so we don't really need
seconds-since-loss, and the new ConnectionStatus doesn't track it anyways.
So now the "Connection" timestamp for non-connected servers is just
"N/A" (both the main text and the tooltip). The "Introducers" section was
changed the same way.
This moves the per-server connection timestamp out of the nickname/serverid
box and over into the Connection box. It also right-floats all timestamps,
regardless of which box they're in, which makes them share the box with
connection_status more politely.
Internally, this adds code to create ConnectionStatus objects when necessary.
which uses SHA1 to combine the file's storage index (known as "peer
selection index" in this context) and each server's "server permutation
seed". This is the only thing in tahoe that uses SHA1.
With this change, we stop importing sha1 from anywhere else.
YAML, like JSON, is all-unicode. StorageFarmBroker.set_static_servers()
is defined to take an all-unicode dictionary (the "storage:" key from
private/servers.yaml), so the server_id keys it gets will be unicode.
NativeStorageServer is defined to accept server_ids which are bytes (at
least it is now). The tests were only passing bytes into
set_static_servers(), whereas a real launch passed unicode in, causing a
problem when NativeStorageServer tried to base32.a2b() the pubkey and
choked on the unicode it received.
This fixes set_static_servers() to convert the server_id to bytes, and
changes NativeStorageServer to assert that it gets bytes. It also fixes
the test to match real usage more closely.
This adds Node._create_tub(), which knows how to make a Tub with all the
right options and connection handlers that were specified in
tahoe.cfg (the connection handlers are disabled for now, but they'll get
implemented soon).
The new Node.create_main_tub() calls it. This main Tub is used:
* to connect to the Introducer
* to host the Helper (if enabled)
* to host the Storage Server (if enabled)
Node._create_tub() is also passed into the StorageFarmBroker, which
passes it into each NativeStorageServer, to create the (separate) Tub
for each server connection. _create_tub knows about the options, and
NativeStorageServer can override the connection handlers. This way we
don't need to pass tub options or default handlers into Client,
StorageFarmBroker, or NativeStorageServer.
A number of tests create NativeStorageServer objects: these were updated
to match the new arguments. test_storage_client was simplified because
we no longer need to mock out the Tub() constructor.
A minimally-defined static server only specifies server_id,
anonymous-storage-FURL, and permutation-seed-base32. But the WUI Welcome
page wouldn't render (it raised an exception) without also defining
nickname and version. This allows those values to be missing.
This follows the latest comments in ticket:2788, moving the static
server definitions from "connections.yaml" to "servers.yaml". It removes
the "connections" and "introducers" blocks from that file, leaving it
responsible for just static servers (I think connections and introducers
can be configured from tahoe.cfg).
This feeds all the static server specs to the StorageFarmBroker in a
single call, rather than delivering them as simulated introducer
announcements. It cleans up the way handlers are specified too (the
handler dictionary is ignored, but that will change soon).
They're the same thing, but knowing that is the responsibility of the
caller, not NativeStorageServer. Try to normalize on "server_id" as the
spelling. Remove support for missing key_s, now that we require V2
introductions.
This is a change I've wanted to make for many years, because when we get
to HTTP-based servers, we won't have tubids for them. What held me back
was that there's code all over the place that uses the serverid for
various purposes, so I wasn't sure it was safe. I did a big push a few
years ago to use IServer instances instead of serverids in most
places (in #1363), and to split out the values that actually depend upon
tubid into separate accessors (like get_lease_seed and
get_foolscap_write_enabler_seed), which I think took care of all the
important uses.
There are a number of places that use get_serverid() as dictionary key
to track shares (Checker results, mutable servermap). I believe these
are happy to use pubkeys instead of tubids: the only thing they do with
get_serverid() is to compare it to other values obtained from
get_serverid(). A few places in the WUI used serverid to compute display
values: these were fixed.
The main trouble was the Helper: it returns a HelperUploadResults (a
Copyable) with a share->server mapping that's keyed by whatever the
Helper's get_serverid() returns. If the uploader and the helper are on
different sides of this change, the Helper could return values that the
uploader won't recognize. This is cosmetic: that mapping is only used to
display the upload results on the "Recent and Active Operations" page.
I've added code to StorageFarmBroker.get_stub_server() to fall back to
tubids when looking up a server, so this should still work correctly
when the uploader is new and the Helper is old. If the Helper is new and
the uploader is old, the upload results will show unusual server ids.

This makes IServer instances responsible for their own network
connections, which will help when we add HTTP-based servers in the
future. The StorageFarmBroker should not care about how the IServer uses
the network, it just provides the announcement (and local config).
As discussed at https://tahoe-lafs.org/trac/tahoe-lafs/ticket/1973 and in
previous pull request #129.
- replace lengthy timestamps with human-readable deltas (eg 1h 2m 3s)
- replace "announced" column with "Last RX" column
- remove service column (it always said the same thing, "storage")
- fix colspan on 'You are not presently connected' message
Previous versions, some with github comments: 3fe9053134 , 486dbfc7bd , and c89ea62580, 9fabb92486, bbd8b42a25
Unlike previous attempts, the tests on this one should pass in any timezone.
(But like current master, will fail with Nevow >=0.12...)
Thanks to an anonymous contributor who wrote some of the tests.

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.
add get_available_space() to NativeStorageServer
It uses a new 'available-space' key in the server's v1 version dict, or falls
back to 'maximum-immutable-share-size' (which presently always has the same
value but could have a different meaning in the future).
This is a squash merge of 9773555bb87fab71145ad7a0e84785a4e92d11f7
