This change drops the memory used for Python processes run by Zulip in
development from about 1GB to 300MB on my laptop.
On the front of safety, http://pika.readthedocs.org/en/latest/faq.html
explains "Pika does not have any notion of threading in the code. If
you want to use Pika with threading, make sure you have a Pika
connection per thread, created in that thread. It is not safe to share
one Pika connection across threads.". Since this code only connects
to rabbitmq inside the individual threads, I believe this should be
safe.
Progress towards #32.
This automatically loads settings, zerver.models.* and
zerver.lib.actions.* when you start `manage.py shell`, which should
save a bit of time basically every time someone uses it.
Fixes#275.
Add call to tools/generate-fixtures in tools/test-backend before
starting the tests. Previously, test-backend could fail if called
after tools/test-js-with-casper had failed.
Fixes#501.
manage_args is set to a list of arguments a few lines later in the
function, making this initialization as the empty string useless and
confusing.
Discovered using mypy.
It's not clear whether this will end up being net negative in value in
the long term since it's kinda hard to understand the output, but in
the short term it should prevent regressions.
It's possible we should just eliminate this mechanism, but this fixes
a proximal problem where the multi-line get_subscribers endpoint
description was being handled wrong.
Travis CI's model of installing every version of postgres on the test
VM and then shutting all the versions other than the one requested
down seems to not work very well with doing apt upgrades. It seems
the best way to resolve this is to just uninstall the versions we
don't need.
The point of the lock is to prevent two deployments happening at the
same time and racing with each other, not to prevent doing any future
deployments after an error happens (which is what the current
implementation does in practice).
Addresses part of #208.
We ran into a bug with the Travis CI infrastructure where it postgres
9.1 is installed on the system, and so when we'd do an apt upgrade
with a new version of 9.1, the 9.1 daemon would end up getting started
and conflict with the 9.3 daemon we were trying to run.
Django's `manage.py runserver` prints a relatively low-information log
line for every request of the form:
[14/Dec/2015 00:43:06]"GET /static/js/message_list.js HTTP/1.0" 200 21969
This is pretty spammy, especially given that we already have our own
middleware printing a more detailed version of the same log lines:
2015-12-14 00:43:06,935 INFO 127.0.0.1 GET 200 0ms /static/js/message_list.js (unauth via ?)
Since runserver doesn't have support controlling whether these log
lines are printed, we wrap it with a small bit of code that silences
the log lines for 200/304 requests (aka the uninteresting ones).
Several of these rules only apply to one of Python and Javascript, and
this simplifies the logic and should make our linter code more readable.
In the process, we add support for per-rule/file pair exclusions to
handle the tab exception for codehilite.py.
