This shows up when you're not running a Zephyr mirroring bot and lets
you use Webathena to have us run it. Obviously needs more docs.
Current problems include:
* supervisorctl reload ends up recreating /var/run/supervisor.sock
with the wrong permissions, so it only works once in a row before
you need to chmod that.
* /etc/supervisor/conf.d needs to be humbug-writeable; this is a clear
local root vulnerability
* This uses SSH and thus is kinda slow.

The davidben-patched-for-roost Zephyr branch (available at
https://github.com/davidben/zephyr/tree/roost) adds Zephyr support for
these options. We also patch python-zephyr to expose them. These
basically let you save your Zephyr tickets and port number to a file,
so that you can later restore them (even potentially after the machine
rebooted). Basically because Zephyr is UDP, the Zephyr server will
continue trying to deliver messages to a particular port number that
was registered for up to 20 minutes after getting an error; so we can
even have downtime and reboot and still get our packets so long as we
restore the sessions within 20 minutes.

Previously it only provided the list of all public streams; now it
allows one to specify any union of some of the following:
* all public streams
* all streams the user subscribed to
(the most relevant being the union of those two, which is what we want
for the "streams" page).
Or:
* all streams in realm (superuser only)
The manual task required is that when this is pushed to prod, we need
to also deploy the new sync-public-streams version to zmirror.

Our .crypt-table parsing code isn't quite correct, in that we don't
handle either the "zcrypt default" or "zcrypt by class/instance" pair
options (for sending messages in either direction) -- you have to be
zcrypting for an entire class. I think this makes sense given that on
the Zulip end we can only enforce anything on a stream level.

Since in the future we might want requests to add subscriptions to
include things like colors, in_home_view, etc., we're changing the
data format for the add_subscriptions API call to pass each stream as

The manual step required here is updating the API version in AFS
available for use with the zephyr_mirror.py system.

At Ksplice we used /usr/bin/python because we shipped dependencies as Debian /
Red Hat packages, which would be installed against the system Python. We were
also very careful to use only Python 2.3 features so that even old system
Python would still work.
None of that is true at Humbug. We expect users to install dependencies
themselves, so it's more likely that the Python in $PATH is correct. On OS X
in particular, it's common to have five broken Python installs and there's no
expectation that /usr/bin/python is the right one.
The files which aren't marked executable are not interesting to run as scripts,
so we just remove the line there. (In general it's common to have libraries
that can also be executed, to run test cases or whatever, but that's not the
case here.)

Realistically, if the bot crashes once, it'll probably crash the next
time too, so I'm not convinced we need this loop at all, but in the
interests of avoiding churn on an extensively tested script, I'm going
to err on the side of the minimal change here.

This adds two characters to the length of our default format field, but
based on a conversation I had with kcr, I think this should probably be
okay. If it's a problem, the symptom we'll see is that certain people
will be unable to send zephyrs with this default format (so, certain
Humbug users will have their forwarding consistently fail).

using the updated version), remove the:

Fixes#602.
I replaced the SIGKILL with a SIGINT, and then catch SIGINT with a
handler. This handler calls cancelSubs if necessary, and can later be
edited to perform other clean-up operations, too. I thought about, in
this same commit, changing the SIGTERM in
maybe_restart_mirroring_script to a SIGINT, but after tracing out the
code paths, I realized that isn't necessary. (The SIGTERM is
necessarily performed on a process that has not subscribed to any
zephyr classes, so cancelSubs is unnecessary. If we do think that we
may want to add additional clean-up operations in the future, though,
then it might be worth investigating changing this SIGTERM.)

Previously, if users of our code put the API folder in their pyshared

can just "import humbug".

The refactoring that we did a couple weeks ago to make the zephyr
mirror script restart itself automatically (by splitting it into
zephyr_mirror.py and zephyr_mirror_backend.py) had a poor interaction
with our code for killing old zephyr_mirror processes (to prevent
double-mirroring). If you manually ran two copies of the outer
mirroring script (zephyr_mirror.py), then the second one would on
startup kill the first one's zephyr_mirror_backend.py children (for
being duplicate zephyr_mirror_backend.py processes that would result
in double-mirroring). However, importantly, it did not kill the first
mirroring script's zephyr_mirror.py parent process, so the first
mirroring script would then proceed to startup up new children. The
process then repeats, with the two scripts' roles reversed.
This issue didn't affect the sharded mirroring case, where I had been
doing the testing of the kill code with that refactoring, because we
don't have a version of the outer zephyr_mirror.py loop for that
situation (a consequence of it being hard to restart the threads
properly with the run_parallel API that we're using to spawn all the
children).

Features include:
* Not forking into two processes (shells out to zwrite to send
instead). This makes life easier since we're not doing concurrent
programming.
* Eliminated a lot of hard-to-read or unnecessary debugging output.
* Adding explanatory test suggesting the likely problem for some
common sets of received messages.
* Much less code duplication.
* Support for testing a sharded zephyr_mirror script (--sharded).
* Use of the logging module to print timestamps -- makes debugging
some issues a lot.
* Only one sleep, and for only 10 seconds, between sending the
outgoing messages and checking that they were received.
* Support for running two copies of this script at the same time, so that
running it manually doesn't screw up Nagios.
* Passed running 100 tests run in a row.

It seems that check-mirroring was reporting a lot of spurious failures
due to it sometimes taking more than 3 seconds for the setup phase of
check-mirroring's receive path to run. So fix this:
(1) Wait a bit more than 3 seconds for the receiver to subscribe to
messages
(2) Subscribe to Humbug messages before forking (we can't do this with
zephyr.init() because python-zephyr gets totally messed up if you use
it from multiple processes with a shared initialization)
(3) Get rid of the old time.sleep(0.x) values that were intended to
make messages arrive in order -- since we're now checking that
messages correctly arrived using set(), they aren't needed.
(4) Use a single request to subscribe to both zephyr classes we need
to subscribe to (saves 1 RTT).
