Having both of these is confusing; TORNADO_SERVER is used only when
there is one TORNADO_PORT. Its primary use is actually to be _unset_,
and signal that in-process handling is to be done.
Rename to USING_TORNADO, to parallel the existing USING_RABBITMQ, and
switch the places that used it for its contents to using
TORNADO_PORTS.
The reason higher expected_time_to_clear_backlog were allowed for queues
during "bursts" was, in simpler terms, because those queues to which
this happens, intrinsically have a higher acceptable "time until cleared"
for new events. E.g. digests_email, where it's completely fine to take a
long time to send them out after putting in the queue. And that's
already configurable without a normal/burst distinction.
Thanks to this we can remove a bunch of overly complicated, and
ultimately useless, logic.
This system can't update stats while the queue is idle, without using
threads for this, but at least we ensure to update the file after
consuming an event if more than MAX_SECONDS_BEFORE_UPDATE_STATS passed
since the last update, regardless of the number of iterations done so
far.
The race condition is described in the comment block removed by this
commit. This leaves room for another, remaining race condition
that should be virtually impossible, but nevertheless it seems
worthwhile to have it documented in the code, so we put a new comment
describing it.
As a final note, this is not a new race condition,
it was hypothetically possible with the old code as well.
This mimics the backend logic for adding the data-attribute -
to know what Pygments language was used to highlight the code
block - in locally echoed messages.
New test added checks our logic for canonicalizing pygments alias
(for both frontend and backend).
Other fixtures and tests amended.
We need this information in the frontend to:
* Display the 'view in playground' option for locally echoed messages.
* When we add a UI settings for realm admins to configure their
playground choices, we'll need to use these canonicalized aliases
for displaying the option.
Hence, this tweaks the tool which generates pygments_data.json to contain
the data we need.
Bumping major PROVISION_VERSION since folks need to provision in both
directions.
Tests amended.
In ae58ed5a7 we decided to echo back the text, when no Pygments lexer
matching that language was found. When we do so, we must take care to
HTML escape the lang before wrapping it in a data-code-language attribute.
Tweaked by tabbott to make clear the escaping is defensive.
This changes the success text of the `subscriber_list_add`
form to display the subscribed and already subscribed users
on success. We also display the user profile as a popover.
Previously we would only display the email ids of the already
subscribed users.
Formatting tweaked by tabbott.
We can compute the intended number of processes from the sharding
configuration. In doing so, also validate that all of the ports are
contiguous.
This removes a discrepancy between `scripts/lib/sharding.py` and other
parts of the codebase about if merely having a `[tornado_sharding]`
section is sufficient to enable sharding. Having behaviour which
changes merely based on if an empty section exists is surprising.
This does require that a (presumably empty) `9800` configuration line
exist, but making that default explicit is useful.
After this commit, configuring sharding can be done by adding to
`zulip.conf`:
```
[tornado_sharding]
9800 = # default
9801 = other_realm
```
Followed by running `./scripts/refresh-sharding-and-restart`.
In development and test, we keep the Tornado port at 9993 and 9983,
respectively; this allows tests to run while a dev instance is
running.
In production, moving to port 9800 consistently removes an odd edge
case, when just one worker is on an entirely different port than if
two workers are used.
tornado.web.Application does not share any inheritance with Django at
all; it has a similar router interface, but tornado.web.Application is
not an instance of Django anything.
Refold the long lines that follow it.
bootstrap sets <code> to use `Monaco` font by default. We don't
want to use this font since some characters are not clearly
readable like `()` appearing as `0`.
Hence, we use Menlo font by default if available.
Since `Monaco` font is only installed in macOS by default, this
mostly affected mac users.
While urllib3 retries all connection errors, it only retries a subset
of read errors, since not all requests are safe to retry if they are
not idempotent, and the far side may have already processed them once.
By default, the only methods that are urllib3 retries read errors on
are GET, TRACE, DELETE, OPTIONS, HEAD, and PUT. However, all of the
requests into Tornado from Django are POST requests, which limits the
effectiveness of bb754e0902.
POST requests to `/api/v1/events/internal` are safe to retry; at worst,
they will result in another event queue, which is low cost and will be
GC'd in short order.
POST requests to `/notify_tornado` are _not_ safe to retry, but this
codepath is only used if USING_RABBITMQ is False, which only occurs
during testing.
Enable retries for read errors during all POSTs to Tornado, to better
handle Tornado restarts without 500's.
This was called in both if and else with the same argument.
I believe there's no reason for it to exist twice and having
it just once would be a bit cleaner.
webfonts-loader now defaults writeFiles to true, which makes spurious
copies of zulip-icons.{css,eot,svg,ttf,woff,woff2} for no reason.

When a fragment (i.e. section starting with `#`) is present in the URL
when landing the development login page, dev-login.js used to append
it to the appends it to the `formaction` attribute of all the input
tag present in the `dev_login.html`.
This made sense before 139cb8026f, which
adjusted the structure of how `next` was passed.
To fix this, we adjust the JavaScript login to set the `next` hidden
input instead.

This makes our icon font smaller. We only reference its glyphs by
Unicode private-use codepoints and not by ligatures.

css-loader@4 broke @import statements referencing files with
extensions other than .css, unless those @import statements are
compiled away by another loader. Upstream is more interested in
arguing that such @import statements are semantically incorrect than
applying the one line fix.

Without an explicit port number, the `stdout_logfile` values for each
port are identical. Supervisor apparently decides that it will
de-conflict this by appending an arbitrary number to the end:
```
/var/log/zulip/tornado.log
/var/log/zulip/tornado.log.1
/var/log/zulip/tornado.log.10
/var/log/zulip/tornado.log.2
/var/log/zulip/tornado.log.3
/var/log/zulip/tornado.log.7
/var/log/zulip/tornado.log.8
/var/log/zulip/tornado.log.9
```
This is quite confusing, since most other files in `/var/log/zulip/`
use `.1` to mean logrotate was used. Also note that these are not all
sequential -- 4, 5, and 6 are mysteriously missing, though they were
used in previous restarts. This can make it extremely hard to debug
logs from a particular Tornado shard.
Give the logfiles a consistent name, and set them up to logrotate.
Making this include "zulip-tornado" makes it clearer in supervisor
logs. Without this, one only sees:
```
