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.
Links to the available message flag table in the feature level 224
changelog entry, as there are relevant **Changes** notes for this
feature level in that part of the API documentation.
Updates the order and formatting of these new and deprecated flags
in the available flags table. Also, adds a link to the topic
wildcard mentions section of the help center documentation.
Makes small clean ups to the changes notes for this feature level,
as well as the changelog entry itself.
The original commit for these feature level 224 API changes was
c597de6a1d.
Refactor `parse_client` view to use `typed_endpoint decorator`
instead of `has_request_variables`. This change improves code consistency
and enhances codebase comprehension.
PostgreSQL's estimate of the number of usermessage rows for a single
message can be wildly off, due to poor statistics generation. This
causes this query, with 100-message batch sizes, to incorrectly
estimate millions of matched rows, causing it to perform a full-table
index scan, rather than piecemeal using the `message_id` index.
Reduce the batch size to 50, which is enough to tip in favor of a
rational query plan.
Refactor `report_csp_violations` view to use `typed_endpoint` decorator
instead of `has_request_variables`. This change improves code
consistency and enhances codebase comprehension.
Depending on the kind of config error being shown, different "go back"
links may be more appropriate.
We probably hard-coded /login/ for it, because these config errors are
most commonly used for authentication backend config error, where it
makes sense to have /login/ as "go back", because the user most likely
indeed got there from the login page.
However, for remote_billing_bouncer_not_configured, it doesn't make
sense, because the user almost surely is already logged in and got there
by clicking "Plan management" inside the gear menu in the logged in app.
It's best for these to just be consistent. Therefore:
1. The .../not-configured/ error page endpoint should be restricted to
.has_billing_access users only.
2. For consistency, self_hosting_auth_view_common is tweaked to also do
the .has_billing_access check as the first thing, to avoid revealing
configuration information via its redirect/error-handling behavior.
The revealed configuration information seems super harmless, but it's
simpler to not have to worry about it and just be consistent.
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.
Adds a re-usable lockfile_nonblocking helper to context_managers.
Relying on naive `os.mkdir` is not enough especially now that the
successful operation of this command is necessary for push notifications
to work for many servers.
We can't use `lockfile` context manager from
`zerver.lib.context_managers`, because we want the custom behavior of
failing if the lock can't be acquired, instead of waiting.
That's because if an instance of this gets stuck, we don't want to start
queueing up more processes waiting forever whenever the cronjob runs
again and fail->exit is preferrable instead.
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.
This commit updates default for delete_own_message_policy
setting to "Everyone" as it is helpful to allow everyone
to delete their own messages in a new organization where
users might be using Zulip for the first time.
This commit updates default for move_messages_between_streams_policy
setting to "Members and above" as it is helpful to allow members
to move messages between streams in new organizations where users
might be using Zulip for first time.
The presence of `len(messages)` outside the transaction caused the
full resultset to be fetched outside of the transaction. This should
ideally be inside the transaction, and also only need be the count.
However, also note that the process of counting matching rows, and
then executing a second query which embeds the same query, is
susceptible to phantom reads, where a query with the same conditions
returns different resultsets, under PostgreSQL's default transaction
isolation of "read committed." While this is possible to resolve by
pulling the returned IDs into a Python list, it would not address the
issue that concurrent updates which change the resultset would make
the overall algorithm still incorrect.
Add a comment clarifying the conditions under which the algorithm is
correct. A more correct algorithm would walk the UserMessage rows
which are unread and in the stream, but this requires a
whole-UserMessage index which would be quite large for such an
infrequent use case.
This makes no immediate reloads the default for runtornado, matching
the production configuration, and changes the development incantation
to be the one to specify the departure from the norm, with
--immediate-reloads.
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.
Due to the channel_map_to_topics URL parameter in the Slack webhook,
it was not migrated to use the check_send_webhook_message.
By using check_send_webhook_message, any topic parameter in the
webhook URL will be prioritized over mapping Slack channels to
topics, e.g. when channel_map_to_topics is true. This is because
the default behaviour for incoming webhooks is to send a default
topic as a parameter to check_send_webhook_message in case there
is no topic specified in the URL.
In contrast, we can override the stream passed in the URL when
channel_map_to_topics is false by passing the Slack channel name
to check_send_webhook_message. The default behaviour for incoming
webhooks is to send a direct message if there is no specified
stream in the URL, so a default stream is not generally passed
to check_send_webhook_message.
