This adds API support to reorder linkifiers and makes sure that the
returned lists of linkifiers from `GET /events`, `POST /register`, and
`GET /realm/linkifiers` are always sorted with the order that they
should processed when rendering linkifiers.
We set the new `order` field to the ID with the migration. This
preserves the order of the existing linkifiers.
New linkifiers added will always be ordered the last. When reordering,
the `order` field of all linkifiers in the same realm is updated, in
a manner similar to how we implement ordering for
`custom_profile_fields`.
The curl examples of reordering linkifiers require there to be some
linkifiers in the database to be reordered. This adjusts some test cases
so they do not assume that there is no linkifier in the test db.
Select the linkifier with `:nth-child` assuming the possibility of other
linkifiers in the realm. This prepares for a later change that requires
us to populate the test database with linkifiers.
Each unittest subTest can fail without interrupting the other subTests.
By wrapping the test for each view function, we can get all validation
errors at once, which can be useful if multiple endpoints are updated.
More importantly, if the test fails anywhere inside test_openapi but
before the formatted output is printed, we will not lose the information
of which view function fails the validation. Because we attach the name
of the function to the subTest:
```
FAIL: test_openapi_arguments (zerver.tests.test_openapi.OpenAPIArgumentsTest) [zerver.views.alert_words.add_alert_words]
```
The number of affected objects may be quite high, and they are
selected by `id IN (...)` query, and updated with a giant `CASE`.
This turns out to be quadratic, and can cause large queries to take
hours, in a state where they cannot be terminated, when PostgreSQL >11
tries to JIT the query.
Set a batch_size as a stopgap performance fix before moving to
`.update()` as a real fix.
Organization owners can make streams private even if they're not
subscribed to them, but cannot access private streams they're not
subscribed to. This means they're able to lock themself out of streams.
This change warns users of this and give them a chance to subscribe.
Fixes#26437.
In commit 5edc8fc, abstract classes were added to the
drafts overlay, but the classes that were already there
were not removed. This resulted in the same styles being
applied twice.
Removes the "dropdown-list-body" class and references as it is no
longer used in the new DropdownWidget. The previous uses of the
class were removed in commit 875d564f2d.
We should have a clear reference in the "Writing messages" sidebar
section on linking to other conversations below "Mention a user
or group" to clarify mentioning users vs linking to conversations.
This adds a link to the "Link to a message or conversation" article
with a different heading.
We have historically cached two types of values
on a per-request basis inside of memory:
* linkifiers
* display recipients
Both of these caches were hand-written, and they
both actually cache values that are also in memcached,
so the per-request cache essentially only saves us
from a few memcached hits.
I think the linkifier per-request cache is a necessary
evil. It's an important part of message rendering, and
it's not super easy to structure the code to just get
a single value up front and pass it down the stack.
I'm not so sure we even need the display recipient
per-request cache any more, as we are generally pretty
smart now about hydrating recipient data in terms of
how the code is organized. But I haven't done thorough
research on that hypotheseis.
Fortunately, it's not rocket science to just write
a glorified memoize decorator and tie it into key
places in the code:
* middleware
* tests (e.g. asserting db counts)
* queue processors
That's what I did in this commit.
This commit definitely reduces the amount of code
to maintain. I think it also gets us closer to
possibly phasing out this whole technique, but that
effort is beyond the scope of this PR. We could
add some instrumentation to the decorator to see
how often we get a non-trivial number of saved
round trips to memcached.
Note that when we flush linkifiers, we just use
a big hammer and flush the entire per-request
cache for linkifiers, since there is only ever
one realm in the cache.
We want to phase out the use of get_display_recipient
for streams, and this is the last place that I
eliminate it. The next commit will eliminate the
dead code and make mypy types tighter.
This change will make push notifications slightly
slower in some situations, but we avoid all the
complexity of a cache, and this code tends to run
offline.
We could always make this code a bit more efficient
by being a little smarter about what data we fetch
up front. For example, get_apns_alert_title gets
called by a function that already has the stream
name. It's just a bit of a pain to refactor when
you have all the DM codepath mucked up with the
stream codepath.
We generally want to avoid extra moving parts when we
stringify objects. We also want to phase out the use
of get_display_recipient for streams.
Note that we still hit get_display_recipient to
stringify DM and huddle objects, and it's kind of ugly
how we do it, but that's outside the scope of my
current PR.
There's no need for the complexity and extra round
trips to call get_display_recipient in a testing
context.
We also eliminate the unnecessary call to check_string.
This function is poorly named, but that's a sweep
for another day.
The get_display_recipient helper is a clumsy way to get
stream names, and it's not even representative of how
most of our code retrieves stream names.
The new helper also double-checks that the Stream
object has the correct recipient id.
We no longer have to reason about the 12 possible
ways of invoking get_narrow_url. We also avoid
double computation in a couple places.
Finally, we get stricter type checks by just inlining
the calls.
We don't need to call get_display_recipient for
non-stream messages.
I will rename display_recipient in the next commit;
if I were to combine the steps the diff would be too
hard to read.
This commit renames the keyword 'pm' to 'dm' in the
'pm_mention_email_disabled_user_ids' and
'pm_mention_push_disabled_user_ids' attributes of the
'RecipientInfoResult' dataclass.
'pm' and 'dm' are the acronyms for 'private message' and
'direct message' respectively.
It includes 'TODO/compatibility' code to support the old format
fields in the tornado queues during the Zulip server upgrades.
This commit renames the 'PRIVATE_MESSAGE' attribute of the
'NotificationTriggers' class to 'DIRECT_MESSAGE'.
Custom migration to update the existing value in the database.
It includes 'TODO/compatibility' code to support the old
notification trigger value 'private_message' in the
push notification queue during the Zulip server upgrades.
Earlier 'private_message' was one of the possible values for the
'trigger' property of the '[`POST /zulip-outgoing-webhook`]' response;
Update the docs to reflect the change in the above-mentioned trigger
value.
This commit adds 'TODO/compatibility' code to support the
old notification trigger values in the push notification queue
during the Zulip server upgrades.
In f4fa82e, we renamed the following notification triggers:
* 'wildcard_mentioned' to 'stream_wildcard_mentioned'
* 'followed_topic_wildcard_mentioned' to
'stream_wildcard_mentioned_in_followed_topic'.
This should have been added in f4fa82e.
This commit adds code to pass all the required arguments to
select_related call for Message objects such that only the
required related fields are fetched from the database.
Previously, we did not pass any arguments to select_related,
so all the directly and indirectly related fields were fetched
when many of them were actually not being used and made the
query unnecessarily complex.
