In addition, CLI functions are allowed to use sys.exit() instead of
always needing to return the exit code as an integer.
runner.py now knows about the blocking httplib calls in scripts/cli and
scripts/magic_folder, and uses deferToThread() to invoke them. Those
functions cannot return a Deferred: when rewrite them to use twisted.web
or treq, we'll remove this deferToThread call.
Option parsing was split out to a separate function for testing. We now
use twisted.internet.task.react() to start the reactor, which required
changing the way runner.py is tested.

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'.

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.

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").

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.
Adds:
- a JSON endpoint
- CLI to display information
- QueuedItem + IQueuedItem for uploader/downloader
- IProgress interface + PercentProgress implementation
- progress= args to many upload/download APIs
Meejah pointed out that new users might think the encoding parameters
are fixed, something you must pick correctly when you first set up the
node, and then are never allowed to change again, which is kind of
anxiety-inducing. This updates the comment to explain that the encoding
is stored in each filecap, and the tahoe.cfg values are only used for
newly-uploaded files.
This allows a python3-based "tox" (as shipped with modern debian and
ubuntu systems) to run setup.py egg_info, update_version, and sdist
commands. It moves the main "tahoe requires py2" check out of setup.py
and into allmydata.scripts.runner.run, where it gets applied at runtime
rather than build time.
It also changes the execfile(_auto_deps.py) and Versioneer-like "ask git
what our version string should be" code to work under both py2 and py3.

test_cli.Help was too sensitive to the way that the --help output was
wrapped, which caused failures on travis when COLUMNS= was set low and
the expected strings were split across separate lines.
Also:
* do some light refactoring of create-client/node
* make it clear that these commands' --basedir options do the same as
the global --node-directory option
* use "global-options" instead of "global-opts"
Subcommands "--help" is now rendered as:
```
tahoe [global-options] COMMAND [options] ARGS
(use 'tahoe --help' to view global options)
USAGE (flags/options)
DESCRIPTION
DESCRIPTION_UNWRAPPED
```
The new .description and .description_unwrapped fields allow
commands (subclasses of twisted.python.usage.Usage) better control over
how their explanations are rendered: the old .longdesc field was wrapped
unpleasantly.
This avoids an error case where an empty child name resulted in a
duplicate mkdir. It adds a precondition check to guard against empty
child names, and some test cases. It also cleans up a funny redundancy
noticed earlier (refs ticket:2329).
This substantially changes the internals of "tahoe cp", to behave in
accordance with the scheme developed in ticket:2329. test_cli_cp.py got
a large new test to exercise all the various combinations. This also
changes the set of error messages that "tahoe cp" can produce.
This modifies try_copy(), inserts a new implementation of
copy_things_to_directory() (and supporting methods), and fixes a few
bugs elsewhere.

This code will be replaced in the next commit with an entirely different
approach, and modifying it in a single commit would yield a completely
unreadable diff.
Instead of constructing a sys.argv for 'twistd' that reads the node's
.tac file, we construct arguments that tell twistd to use a special
in-memory-only plugin that creates the desired node instance directly.
We still use the name of the .tac file to decide which kind of instance
to make (Client, IntroducerNode, KeyGenerator, StatsGatherer), but never
actually read the contents of the .tac file. Later improvements could
change this to look inside the tahoe.cfg for a nodetype= directive, etc.
This also makes it easy to have "tahoe start BASEDIR" pass the rest of
its arguments on to twistd, so e.g. "tahoe start BASEDIR --nodaemon
--profile=prof.out" does what you'd expect "twistd --nodaemon
--profile=prof.out" to do. "tahoe run BASEDIR" is thus simply aliased to
"tahoe start BASEDIR --nodaemon". This removes the need to special-case
--profile and --syslog.
I also removed some of the default logging behavior:
before:
'tahoe start' = 'twistd --logfile BASEDIR logs/twistd.log'
'tahoe start --profile' adds '--profile=profiling_results.prof --savestats'
'tahoe run' = 'twistd --nodaemon --logfile BASEDIR/logs/tahoesvc.log'
after:
'tahoe start' = 'twistd --logfile BASEDIR logs/twistd.log'
unless --logfile, --nodaemon, or --syslog are passed
'tahoe start --profile' invalid, use 'tahoe start --profile=OUTPUT'
'tahoe run' = 'twistd --nodaemon'
so log messages go to stdout
This finally enables 'tahoe run' to work with all node types, including
the key-generator and stats-gatherer.
It gets 'tahoe start' one step closer to accepting --reactor= . To
actually accomplish this will require this file, the enclosing
__init_.py files, and everything they import to avoid importing the
reactor. (if anything imports twisted.internet.reactor before
startstop_node.start() gets to run, then --reactor= comes too late).
That will take a lot of work, and requires lazy-loading of many core
libraries (foolscap.logging in particular), and removing a lot of code
from src/allmydata/__init__.py .
The new rules for "bin/tahoe ARG1.. SUBCOMMAND ARG2.." arg:
* --node-directory is only accepted in ARG1, not ARG2
* create-*/start/stop/restart accept --basedir in ARG2, or an explicit
basedir argument
* only one of --node-directory/--basedir/explicit-basedir is accepted
* --quiet/--version is only accepted in ARG1, not ARG2
Closes#166
* 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
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.
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.)
