Tornado reloads the app whenever there is a change in code. Due to this,
new connection is created to the client which also results in a new
channel. To avoid creating two channels for the queue in the RabbitMQ
broker we should close the old channel. Otherwise messages sent to the
queue will be distributed among these two channels in a round robin
scheme and we will end up losing one message since one of the channels
doesn't have an active consumer.
This commit closes the connection to the queue whenever Tornado reloads
the application using add_reload_hook().
Fixes#5824.
We do not need to test the exception message being logged in every
test case where an exception is raised by a webhook function.
Testing it once should be enough; this makes the tests less
verbose.
If an incoming payload contained a unicode character, it raised
a UnicodeEncodeError, because the message template was an str. Now,
the message template is unicode, so it can be formatted to include
unicode characters, should the incoming payloads contain any.
Splitting bot_lib.py file into 2 files led to unnecessary
redirection of the code workflow. For an embedded bot/service to
send a reply, it was being redirected 3 times.
First, the code flow comes to "EmbeddedBotHandler" class to send
reply, then it goes to the common function in "zulip_bots/lib.py",
then it would come back to "EmbeddedBotHandler". Later on, if we
create an abstract class, from where the bot work flow would
directly hit and then from there it is classified into
EmbeddedBotHandler or ExternalBotHandler and accordingly it would
get redirected.
Now, first the bot flow goes to it's handler class External or
Embedded (where we pass that this is External or Embedded bot as
parameter) and then goes to a common point and then comes back to
the same class.
Exception logging within api_key_only_webhook_view fails when
ValueError is raised if the request.body passed to ujson.loads
isn't valid JSON. In this case, we now just convert the payload
to a string and log that. This allows us to inspect JSON payloads
that aren't being decoded properly.
This fixes a performance issue that caused this migration to run for a
really long time.
It still takes about 1 minute to run with the 75K Subscription objects
we have on chat.zulip.org, but that's within the realm of acceptable.
This is required, since we just reorganized the python-zulip-api
repository into 3 packages.
A nice side effect is that we get to eliminate some now-unnecessary
code for editing sys.path.
Also adds Confirmation.type, and cleans up the rest of Confirmation to look
more like the model definitions in zerver.
In the migration, all existing confirmations adopt the type
USER_REGISTRATION, to be conservative. In a few commits, different
confirmation types will have different validity periods, and
USER_REGISTRATION will have the shortest default.
In most cases, we do have the data for which other user was
responsible for subscribing the target user to new streams.
The main case where we don't is when the user is created and gets the
default streams.
ScheduledJob was written for much more generality than it ended up being
used for. Currently it is used by send_future_email, and nothing
else. Tailoring the model to emails in particular will make it easier to do
things like selectively clear emails when people unsubscribe from particular
email types, or seamlessly handle using the same email on multiple realms.
