Previously, "tahoe create-node" without an --introducer= argument would
result in the literal string "None" being written into tahoe.cfg:
[client]
introducer.furl = None
We were using config.get("introducer",""), but that didn't suffice because
the key was actually present: it just had a value of None, which then got
stringified into "None" when writing out tahoe.cfg.
This briefly caused test/cli/test_create to fail, as the startup code tried
to parse "None" as a FURL. This only happened against a development version
of Foolscap which accidentally became sensitive to unparseable FURLs in
started Reconnectors. I fixed that in the final foolscap-0.12.5 release, so
we shouldn't hit this bug, but I wanted to fix it properly in the tahoe-side
source.
As discussed in this week's meeting, since we don't yet know why some
flavors of linux have slightly different inotify behavior than others,
and since we believe the actual functionality is not significantly
impacted, and since the red buildbot is reducing our confidence that the
other tests are passing, and since we have a release coming up: we're
marking the one troublesome test as ".todo". We expect that the test
will be fixed soon (perhaps to accept either 3 or 4 events), but not
necessarily before the 1.12 release.

This forces the Uploader and Downloader to implement a _scan_delay
method and makes the naming more consistent with what's actually
happening. Also, fix a few "bugs" in the names of args in the
mocks for some tests.
We use it for two things: to create the foolscap connection handler, and
to possibly start an .onion listener at startup.
This also updates node._common_config_sections to accept the new tor
settings written by create-node/create-introducer.
This adds tor-related CLI arguments to "create-node" and
"create-introducer", to control exactly how we should be using Tor.
* --tor-launch
* --tor-executable=
* --tor-control-port=
I went with "--tor-launch" instead of "--launch-tor" for consistency. I
don't particularly like the grammatical flow of it, and it doesn't
actually put all the tor-related arguments next to each other in the
--help output (the flags are put in one block, then the parameters in
the next). But it seems slightly more consistent to start all the
tor-related argument names with a "--tor*" prefix.
This uses a unix-domain control port, and includes test coverage.
create_onion() displays pacifier messages, since the allocate-onion step
takes around 35 seconds
All server-like nodes (storage servers and introducers both) will need
this for the tor state directory and .onion private key file, and it
needs to exist before the config is written, so tor onion-service
private keys can be placed there.
Also remove a redundant import.
This puts the right inlineCallbacks in place to allow
write_node_config() to return a Deferred. The upcoming Tor support will
need this (since it must wait for an .onion address to be allocated
before it can write tahoe.cfg's tub.port and tub.location lines).
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.
I think the preferred way to listen on both IPv4 and IPv6 will be to use
"--port=tcp:PORT,tcp6:PORT". This is now reflected in the docs.

This enables an I2P-only node, which disables TCP entirely (instead of
mapping TCP to Tor, which was the only other option that
reveal-IP-address=False would allow).
