Prevent a non-immediate reload from being scheduled while an immediate
reload is already in progress. This is highly unlikely in practice,
but is a reasonable safeguard.
A `reload.initiate({immediate: true, ...})` *should* not return, as it
should trigger a `window.location.reload` and stop execution.
In the event that it continues execution and returns (for instance,
due to being in the background and reloads being suppressed for
power-saving -- see #6821), there is no need to fall through and
potentially schedule a 90-second-later retry.
PostgreSQL's `default_statistics_target` is used to track how many
"most common values" ("MCVs") for a column when performing an
`ANALYZE`. For `tsvector` columns, the number of values is actually
10x this number, because each row contains multiple values for the
column[1]. The `default_statistics_target` defaults to 100[2], and
Zulip does not adjust this at the server level.
This translates to 1000 entries in the MCV for tsvectors. For
large tables like `zerver_messages`, a too-small value can cause
mis-planned query plans. The query planner assumes that any
entry *not* found in the MCV list is *half* as likely as the
least-likely value in it. If the table is large, and the MCV list is
too short (as 1000 values is for large deployments), arbitrary
no-in-the-MCV words will often be estimated by the query planner to
occur comparatively quite frequently in the index. Based on this, the
planner will instead choose to scan all messages accessible by the
user, filtering by word in tsvector, instead of using the tsvector
index and filtering by being accessible to the user. This results in
degraded performance for word searching.
However, PostgreSQL allows adjustment of this value on a per-column
basis. Add a migration to adjust the value up to 10k for
`search_tsvector` on `zerver_message`, which results in 100k entries
in that MCV list.
PostgreSQL's documentation says[3]:
> Raising the limit might allow more accurate planner estimates to be
> made, particularly for columns with irregular data distributions, at
> the price of consuming more space in `pg_statistic` and slightly
> more time to compute the estimates.
These costs seem adequate for the utility of having better search.
In the event that the pgroonga backend is in use, these larger index
statistics are simply wasted space and `VACUUM` computational time,
but the costs are likely still reasonable -- even 100k values are
dwarfed by the size of the database needed to generate 100k unique
entries in tsvectors.

In `JsonableErrorHandler`, we convert `MissingAuthenticationError` into

The dangling comment was not very helpful and unclear about the pieces
of code it was referring to.
We expand the part about linking the prereg_user to the created user,
while the part about "revoking other preregistration users" is
redundant, because the relevant code block lower down already has
comments on it with better explanations.
Closes#22274.
This assertion was added in 4b903c5dcd
where it may have made sense, because indeed when doing realm creation
there was always a PreregistrationUser (created because realms were
created via going to a generated realm creation link). With the addition
of the create_realm command that's no longer the case.
It would be unnatural to create a PreregistrationUser in the
realm_creation command, because there is no confirmation link for it to
be tied to - and it just doesn't make sense conceptually.
The intended, correct behavior added in
4b903c5dcd is still maintained - the code
lower down correctly handles the
(prereg_user is None and realm_creation) case.
The type safety of a TypeGuard is unchecked by mypy. While this
particular TypeGuard is safe given the current context, one could
imagine future changes that make it unsafe, so it’s preferable to
avoid unchecked constructs whenever possible.

The field_data sent from client while creating a select
type field is a dict with a number as key.
In development database the field data for "Favorite editor"
field was of different form where the option label was used
as key in the dict.
This commit fixes it to be of the same as it is when creating
a field from web-app. As a result, we also need to update
the tests and this commit also update field_data for other
select-type fields.
We show a confirmation modal when deleting option of a select-type
field mentioning number of users who are using that option. We also
show the modal if no user has selected that option. We show the modal
only in edit-form and not while creating a new profile field. We do
not show the modal when removing a newly added option during editing
the field.
Fixes#22145.
Previously, the value for an option of the select type custom
profile field was set as "order - 1". This commit changes it
to remain same even when we reorder the options or delete an
option. When we add a new option, its value is set as 1 more
than largest value already used.
This helps is eliminating various bugs in this subsystem, where
user's choice is changed unexpectedly when reordering or deleting
options.

This immediately shows the menu for which messages to move when the
user can edit the stream/topic of a message, but not the content of
the message. This balances the concern that this menu might feel like
clutter when doing a content edit with the fact that most of the time
when one visits this menu without content edit permissions, one will
want to be reassured that one can choose which messages to move.
Fixes#19196.
Adds a section for writing and style guidlines to the tutorial
for writing help center articles. Moves the sections on 'Voice'
and 'User interface' to be in the new section, and adds a section
on 'Keyboard shortcuts'.
Adds a shared file with general information about Zulip's
translation project based on the text in web-app's language
picker, and uses that text at the beginning of the help articles
for setting the organization notifications/announcement language
and for the user setting their personal language setting.
Also makes some small edits/updates to the help center article
about the user's personal language setting to align with current
UI and current documentation styles.
When being called, the wrapped function is passed `PaymentIntent`
(the `content_object` of `Event`). With that, since `customer` can be
`None`, an assertion is also required.

This change ensures that we can call the validate and update helper for
custom profile data later.

We refactor the validator of `update_user_custom_profile_data` to ensure
that the validated variable is properly typed as
a `ProfileDataElementUpdateDict`, so we can call
`validate_user_custom_profile_data` and
`do_update_user_custom_profile_data_if_changed` directly later (unlike
`update_user_backend`, where `value` is allowed to be `None`, the
validator already ensures that no further check is required).
django-stubs types the return type of query.values(...) as a TypedDict.
This makes Dict[str, Any] that we have been using incompatible with it.
We use TypeGuard to ensure that `service_bot_tuples` is correctly
inferred to be `Tuple[int, int]` instead of `Tuple[int, Optional[int]]`.
Given that `bot_type` is optional for `ActiveUserDict`, we need to
narrow `row` to `ActiveBotUserDict` to make sure that `bot_type` is
non-optional. An advantage of this approach is that no assertions or
type casts are needed.

StreamingHttpResponse is inferred without the isinstance check in the
else branch. We refactor this is shorten the code and also type narrow
it appropriately.
`request.method` is not `None` in normal use cases, unless an
`HttpRequest` is directly instantiated without the method being set.
This situation does not apply to `WSGIRequest` at all.

Asserting response.stream is False is just suggesting the response being
an `HttpResponse`. This removes `StreamingHttpResponse` with the more
generic `HttpResponseBase` with an isinstance-check.
