The previous model for these Nagios checks was kinda crazy -- every
minute, we'd run a full `rabbitmctl list_consumers` for each of the
dozen+ consumers that we have, and then do the exact same parsing
logic for each to determine whether the target queue has a running
consumer to write out a state file.
Because `rabbitmctl list_consumers` takes a small amount of resources,
on systems where CPU is very limited (e.g. t2 style AWS instances),
this minor CPU wastage could be problematic.
Now we just do that `rabbitmqctl list_consumers` once per minute, and
output all the state files from a single command.
Further TODO items on this front include removing the hardcoded list
of queues.
Previously, missed message emails with multiple senders would
incorrectly have a "," outside the quoted sender name part of the from
address string, resulting in confusing email output.
This commit introduces the ability to do custom fetches
and to essentially use temp tables for intermediate results.
(The temp table stuff deals with recipients/subscriptions
having three different flavors--user, stream, and huddle.)
Because rabbitmq doesn't support changing the nodename of a running
rabbitmq node, Zulip installations suffered a plague of issues where
e.g. a Zulip server would reboot, the hostname would change, and
suddenly the local rabbitmq instance being used by Zulip would stop
working.
We address this problem by using, by default, a fixed rabbitmq
nodename, but providing server administrators the option to set the
rabbitmq nodename used by Zulip however they choose.
To upgrade an existing server to use this new configuration, one will
need to add something like the following to /etc/zulip/zulip.conf:
[rabbitmq]
nodename = zulip@localhost
However, I don't believe we have the puppet code in place to make this
work correctly at initial installation without rabbitmq-server being
already installed (but off), as we can easily setup in Travis CI but I
haven't been willing to do for the installer. So for now, this just
fixes our Travis CI problems.
Fixes: #1579.
Travis CI seems to have changed the way the snakeoil SSL certs are
generated in their infrastructure, so we need to update our expected
"success" HTTP headers accordingly.
Most directly useful for the migration to zulipchat.com.
Creates a new field in UserProfile to store the tos_version, as well as two
new settings TOS_VERSION and FIRST_TIME_TOS_TEMPLATE. We check for a version
mismatch between what the user has signed and the current
settings.TOS_VERSION whenever the user hits the home page, and redirect them
if needed.
Note that accounts_accept_terms.html and
zerver.views.accounts_accept_terms were unused before this commit
(they date from c327446537)
Previously, we used a fixed memcached memory allocation of 512MB,
regardless of the size of the server. While that is a good allocation
for a server with 4GB of RAM, for servers with less, we should
decrease the allocation, and for a large server with much more RAM, we
should increase it. We still support the user overriding the
configuration setting, but this produces more sensible defaults.
Zulip had only patches the redis configuration in one small way, which
resulted in unnecessary portability issues for using Redis on
different versions of Linux. We replace this with just a adding an
include mechanism to the redis config.
While we're at it, we configure this to take advantage of the
new REDIS_PASSWORD secret to automatically configure redis passwords.
The function to create the message partial files has been
renamed to export_partial_message_files(). It now gets its own
list of user profile ids and recipient ids from the response,
so that we can de-clutter do_export_realm().
The name avatar_bucket was confusing for a boolean, and
in some places it was used for non-S3 paths.
I considered the more concise 'is_avatar', but that
was still confusing when you are processing multiple
files, because you think it's a calculated property
on one file instead of an overall codepath switch.
I also considered splitting up some functions, but
there is a lot of common logic between handling
file uploads and avatars that's not trivial to extract
into helpers, especially on the S3 side.
I did some minor moving around of code that made us have
one fewer function without any additional conditional
logic. The names are more explicit about saying
"from_local" and "from_s3". Also, there is less clutter
now in do_export_realm(), which is evolving into more of
a dispatcher and less of a worker.
When we refactored zilencer to use a single urls.py file in
bf50dd7771, we accidentally lost the
prefix on the API urls.
This broke sending error report emails if zilencer was enabled.
It seems that we no longer get the message, 'zerver/lib/actions.py
modified; restarting server', but the server reloads successfully
nonetheless.
Fixes: #1341.
