Links to zulip messages can now be written as
`#**channel_name > topic_name @ message_id**.`
The `message_id` is replaced with `💬` in the rendered
message.
Fixes part of #31920
There is no behavioral changes to deactivated users as we do
not create UserMessage rows or call the notification code path
for deactivated users in a user group mention. But it is better
to not include the deactivated users in fields like
"mention_user_ids", so this commit updates the code to not
include deactivated users in the computed mention data.
We create an unnamed user group with just the group creator as it's
member when trying to set the default. The pattern I've followed across
most of the acting_user additions is to just put the user declared
somewhere before the check_add_user_group and see if the test passes.
If it does not, then I'll look at what kind of user it needs to be set
to `acting_user`.
Show user card popover for scheduled messages overlay, compose box
preview, message edit preview, message edit history.
`.messagebox` was chosen as the selector since that was the nearest
parent class that was common for all of the above.
`@all` does not have a popover and that's why it will have the same
pointer as its parent element. We also introduce a new class called
`.user-mention-all` for managing css rules specific to that mention.
Updates the base hash for the streams setting overlay to be
"channels" instead of "streams".
Because there are Welcome Bot and Notification Bot messages that
would have been sent with the "/#streams" hash, we will need to
support parsing those overlay hashes as an alias for "/#channels"
permanently.
Part of the stream to channels rename project.
This timeout strategy using asynchronous exceptions has a number of
safety caveats (read the docstring!!) and should only be used in very
specific circumstances.

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.
549dd8a4c4 changed the regex that we build to contain whitespace for
readability, and strip that back out before returning it.
Unfortunately, this also serves to strip out whitespace in the source
linkifier, causing it to not match expected strings.
Revert 549dd8a4c4.
Fixes: #27854.
Previously, when a deactivated user was mentioned, he wasn't
rendered as a Pill. This is because the dataset for validating mentions
only included active users, which is fixed by removing that filter.
To allow only silent mentions of them, an extra is_active property
added to FullNameInfo class, which is populated from the query,
which tells if user is deactivated. This is used to convert any
mentions of them to silent mentions in the backend markdown.
Fixes#26857
This commit moves constants for system group names to a new
"SystemGroups" class so that we can use these group names
in multiple classes in models.py without worrying about the
order of defining them.
When searching for links inside a topic name, the question mark (?)
was used to split the topic. If a URL had a query after the URL
(e.g., "?foo=bar"), then the query was trimmed from the URL.
Removing the question mark from `basic_link_splitter` is sufficient
to fix this issue. The `get_web_link_regex` function then removes
the trailing punctuation if any, including literal question marks.
Fixes#26368.
Fixes#11767.
Previously multi-character emoji sequences weren't matched in the
emoji regex, so we'd convert the characters to separate images,
breaking the intended display.
This change allows us to match the full emoji sequence, and
therefore show the correct image.
We do not set realm to Message objects defined for markdown tests
and this works because we currently access realm from sender object.
This commit changes the code to set realm in Message objects as
we would be accessing realm from Message object directly in further
commits.
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.
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.
Updates the realm field `default_code_block_language` to have a default
value of an empty string instead of None. Also updates the web-app to
check for the empty string and not `null` to indicate no default is set.
This means that both new realms and existing realms that have no default
set will have the same value for this setting: an empty string.
Previously, new realms would have None if no default was set, while realms
that had set and then unset a value for this field would have an empty
string when no default was set.
