Replace a separate call to subprocess, starting `node` from scratch,
with an optional standalone node Express service which performs the
rendering. In benchmarking, this reduces the overhead of a KaTeX call
from 120ms to 2.8ms. This is notable because enough calls to KaTeX in
a single message would previously time out the whole message
rendering.
The service is optional because he majority of deployments do not use
enough LaTeX to merit the additional memory usage (60Mb).
Fixes: #17425.
Just shows a config error page if the bouncer is not enabled. Uses a new
endpoint for this so that it can work nicely for both browser and
desktop app clients.
It's necessary, because the desktop app expects to get a json response
with either an error or billing_access_url to redirect to. Showing a
nice config error page can't be done via the json error mechanism, so
instead we just serve a redirect to the new error page, which the app
will open in the browser in a new window or tab.
Only affects zulipchat, by being based on the BILLING_ENABLED setting.
The restricted backends in this commit are
- AzureAD - restricted to Standard plan
- SAML - restricted to Plus plan, although it was already practically
restricted due to requiring server-side configuration to be done by us
This restriction is placed upon **enabling** a backend - so
organizations that already have a backend enabled, will continue to be
able to use it. This allows us to make exceptions and enable a backend
for an org manually via the shell, and to grandfather organizations into
keeping the backend they have been relying on.
When a server doesn't submit a remote realm info which was
previously submitted, we mark it as locally deleted.
If such a realm has paid plan attached to it, we should investigate.
This commit adds logic to send an email to sales@zulip.com for
investigation.
LoggingCountStats with a daily duration and that are directly stored
on the RealmCount table (not via aggregation in process_count_stat),
can be in a state, after the hourly cron job to update analytics
counts, where the logged value will be live-updated later, because
the end time for the stat is still in the future.
As these logging counts are designed to be used on the self-hosted
installation for either debugging or rate limiting, sending these
partial/incomplete counts to the bouncer has low value.
This commit adds a realm-level setting named
'zulip_update_announcements_stream' that configures the
stream to which zulip updates should be posted.
Fixes part of #28604.
The previous logic incorrectly used the server-level number of users
even when a (presumably smaller) realm-level count was available.
Fixes a bug introduced in 2e1ed4431a.
This commit renames the realm-level setting
'signup_notifications_stream' to 'signup_announcements_stream'.
The new name reflects better what the setting does.
This commit renames the realm-level setting 'notifications_stream'
to 'new_stream_announcements_stream'.
The new name reflects better what the setting does.
RemoteRealm customer takes precedence over RemoteServer
in general. But if an inactive plan is associated with
RemoteRealm and an active plan with RemoteServer, the
ACTIVE plan takes precendence.

Previously, in DM disabled org messaging to bot was not working when
starting new conversation and adding bot as recipient because of not
updating on recipient change. And secondly, self messaging was not
allowed.
This commit ensures that the DM to bot and self are allowed irrespective
of dm restrictions.
tests: Verify DMs adhere to DM restriction policy.
Fixes#28412

The widening of the time between when a process is marked for
reload (at Tornado startup) and when it sends reload events makes it
unlikely-to-impossible that a single `/` request will span both of
them, and thus hit the WebReloadClientError corner case.
Remove it, as it is not worth the complication. The bad behaviour it
is attempting to prevent (of a reload right after opening `/`) was
always still possible -- if the `/` request completed right before
Tornado restarted -- so it is not clear that it was ever worth the
complication.
Collapsing was done incorrectly, as 65c400e06d added `zulip_version`
and `zulip_feature_level`, but did not update the virtual event logic
to copy those new values into the virtual event.
However, it is unlikely that a server will be upgraded multiple times
in quick enough succession for this to ever be relevant. Remove the
logic, which is additional complication for little or no gain.
Having a non-identity `cache_transformer` is no different from running
it on every row of the query_function. Simplify understanding of the
codepath used in caching by merging the pieces of code.
Rather than pass around a list of message objects in-memory, we
instead keep the same constructed QuerySet which includes the later
propagated messages (if any), and use that same query to pick out
affected Attachment objects, rather than limiting to the set of ids.
This is not necessarily a win -- the list of message-ids *may* be very
long, and thus the query may be more concise, easier to send to
PostgreSQL, and faster for PostgreSQL to parse. However, the list of
ids is almost certainly better-indexed.
After processing the move, the QuerySet must be re-defined as a search
of ids (and possibly a very long list of such), since there is no
other way which is guaranteed to correctly single out the moved
messages. At this point, it is mostly equivalent to the list of
Message objects, and certainly takes no less memory.
Rather than use `bulk_update()` to batch-move chunks of messages, use
a single SQL query to move the messages. This is much more efficient
for large topic moves. Since the `edit_history` field is not yet
JSON (see #26496) this requires that PostgreSQL cast the current data
into `jsonb`, append the new data (also cast to `jsonb`), and then
re-cast that as text.
For single-message moves, this _increases_ the SQL query count by one,
since we have to re-query for the updated data from the database after
the bulk update. However, this is overall still a performance
improvement, which improves to 2x or 3x for larger topic moves. Below
is a table of duration in seconds to run `do_update_message` to move a
topic to a new stream, based on messages in the topic, for before and
after this change:
| Topic size | Before | After |
| ---------- | -------- | ------- |
| 1 | 0.1036 | 0.0868 |
| 2 | 0.1108 | 0.0925 |
| 5 | 0.1139 | 0.0959 |
| 10 | 0.1218 | 0.0972 |
| 20 | 0.1310 | 0.1098 |
| 50 | 0.1759 | 0.1366 |
| 100 | 0.2307 | 0.1662 |
| 200 | 0.3880 | 0.2229 |
| 500 | 0.7676 | 0.4052 |
| 1000 | 1.3990 | 0.6848 |
| 2000 | 2.9706 | 1.3370 |
| 5000 | 7.5218 | 3.2882 |
| 10000 | 14.0272 | 5.4434 |
This applies access restrictions in SQL, so that individual messages
do not need to be walked one-by-one. It only functions for stream
messages.
Use of this method significantly speeds up checks if we moved "all
visible messages" in a topic, since we no longer need to walk every
remaining message in the old topic to determine that at least one was
visible to the user. Similarly, it significantly speeds up merging
into existing topics, since it no longer must walk every message in
the new topic to determine if the user could see at least one.
Finally, it unlocks the ability to bulk-update only messages the user
has access to, in a single query (see subsequent commit).
