These are obsolete. Tests are run with 'tox', or by running 'trial
allmydata' from a populated virtualenv. A populated virtualenv is also
the right way to get a repl: just run 'python'.

The google image chart API has been deprecated since 2012, sending the
URL to google leaks server IDs and the client's IP address (especially
important when the client is otherwise behind Tor), and the X-axis has
no units anyways.
refs ticket:1942 , which is both about removing the URL-based chart, and
eventually replacing it with a browser-rendered d3.js-based one
So "tahoe create-node --hide-ip" causes "reveal-IP-address = false" to
get written into tahoe.cfg . This also changes the default tahoe.cfg to
include "reveal-IP-address = true", for clarity.

(instead of using a copy). Foolscap-0.12.3 fixes a problem with
allocate_tcp_port() that was causing intermittent test failures. I think
it makes more sense to use Foolscap's copy (and fixes) than to keep
re-copying it into Tahoe each time it changes.
If/when we manage to stop depending upon foolscap for server RPC, we can
re-copy this back into tahoe's source tree.

We now use::
tub.port = disabled
tub.location = disabled
instead of using an empty value (but the key still being present, since
if the key is missing entirely, that means "be automatic").

This was triggered when the initial Introducer connection failed, so the
node read the introducer_cache.yaml from disk. That always returns
unicode strings, and the StorageFarmBroker insisted that it's
server-IDs (aka "key_s") were bytestrings.
The tests were extended to exercise the code that loads from disk and
delivers to the StorageFarmBroker, and more preconditions were put in
place to catch this sort of thing earlier next time.

This adds a safety flag named `[node] reveal-IP-address`, for which the
default value is True. When this is set to False, any configuration that
might reveal the node's IP address (to servers, or the external network)
will cause a PrivacyError to be raised at startup, terminating the node
before it gets a chance to betray the user's privacy. It also adds docs
and tests.

This only catches txtorcon not being installed (which should be fixed by
doing `pip install tahoe-lafs[tor]`). It doesn't notice that the Tor
daemon is not running (which we can't detect during startup, only
afterwards, when it's harder to notify the user), in which case Tor
connections (and all connections when "tcp = tor" is enabled) will just
fail silently.
This introduces a py.test-based integration suite (currently just
containing magic-folder end-to-end tests). Also adds a tox environment
("integration") to run them.
The test setup is:
- a "flogtool gather" instance
- an Introducer
- five Storage nodes
- Alice and Bob client nodes
- Alice and Bob have paired magic-folders
Updated config docs. Added errors if we're not listening but were told
to enable storage, helper, or if we're the Introducer server.

"gifts" are third-party references (where Alice sends Bob a reference to
Carol, and Carol lives in a different Tub than either Alice or Bob).
Tahoe doesn't currently use these, and they make it possible for e.g. a
server to provoke a client into making a connection to an IP address of
the server's choosing. If the client isn't configured otherwise, this
would use raw TCP (revealing the client's IP address) even if the
connection to the server used Tor.
A connection policy of `tcp: tor` would block this, but it seems like a
good idea to disable gifts entirely.

Foolscap has limitations that prevent us from accepting anything but a
TCP endpoint, but that will change in the future, so make the tahoe.cfg
syntax accept an endpoint, but then reject non-TCP ones. See the ticket
for details: refs ticket:2813.
This depends upon the new `foolscap.connections.tor.socks_port(host,
port)` API in foolscap-0.12.2, so it bumps the dependency to that (the
previous commit depended upon 0.12.1, but I hadn't gotten around to
updating the dep before now).
Note that many of the Foolscap handler-creation functions are still
stubbed out, so Tahoe won't be able to honor the full range of config
syntax until foolscap support is complete.
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.
The node now attempts to create Tor/I2P connection handlers (if the
right libraries are available), and will use them for tor/i2p FURL hints
by default. For now it only creates default handlers: there is not yet
any code to interpret the `[tor]`/`[i2p]` sections of tahoe.cfg which
would let you override that process.
The node also parses the `[connections]` section, allowing `tcp: tor` to
use Tor for all outbound TCP connections. It defaults to `tcp: tcp`, of
course.
Static storage-server connections will now honor the `connections:`
overrides in `servers.yaml`, allowing specific servers to use TCP where
they would normally be restricted to Tor.

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 re-factors the magic-folder tests to abstract
the whole "do a file operation" so we can properly
send fake (or wait for real) inotify events to the
uploader/downloader. This speeds up the tests quite
a bit and makes test_alice_bob reasonable again (at
about 1.5s instead of over 30s).
We no longer need the complexity of choosing the application name at
runtime. This removes the setup.py code which populates the _appname.py
file, and the code in __init__.py which reads it. It does not yet remove
the tests which compare the output of e.g. `tahoe --version` against
`allmydata.__appname__`, which I think could be removed, but that's more
invasive than I want to do right now.

This doesn't reveal very much information, but does tell
you if magic-folder is currently working and if not it will
indicate when the last attempt to do a remote scan was.
Improve error-handling for directories if you ask for JSON from
the /uri endpoint, but an error occurs (you get a proper HTTP
status code and a valid JSON object).
For 'tahoe magic-folder status' e now retrieve *all* the remote data
required in the CLI before doing anything else so that errors can be
shown immediately. Use the improved JSON endpoints to print better
errors.
