roanster007 dc492867af user_mention: Fix mentions of deactivated users.
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

Sahil Batra e458b73a01 user_groups: Move constants for system group names to a new class.
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.

Adrián Oliva 732ad89f3d markdown: Fix URL link topic skipping query.
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.

evykassirer 0289beb784 emoji: Match emoji sequences in markdown.
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.

Sahil Batra 4f30447b95 test_markdown: Set realm for Message objects.
We do not set realm to Message objects defined for markdown tests
and this works because we currently access realm from sender object.

we would be accessing realm from Message object directly in further
commits.

Zixuan James Li 37660dd0e7 linkifier: Support reordering linkifiers.
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`.

Zixuan James Li 011b4c1f7a populate_db: Populate linkifiers.

Steve Howell 51db22c86c per-request caches: Add per_request_cache library.
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.

Lauryn Menard 1cccdd8103 realm-settings: Make default_code_block_language empty string as default.
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.

Prakhar Pratyush 0891f9f65a mention: Determine @topic mention during message rendering.
This commit adds a boolean field `mentions_topic_wildcard`
to the `MessageRenderingResult` dataclass.

The field is set to true only if message rendering determines
the message has an actual topic wildcard mention in it (and not,
e.g., topic wildcard mention syntax inside a code block).

The rendered content for topic wildcard mention is
'<span class="topic-mention">{wildcard}</span>'.

The 'topic-mention' class is the identifier for the wildcard
mention being a topic wildcard mention.

We don't use 'data-user-id="*"' and "user-mention" class for
topic wildcard mentions and eventually plan to remove them for
stream wildcard mentions too in a separate mini-project.

Prakhar Pratyush 806d8f2dc7 test_markdown: Merge similar tests into a single test case.
This prep commit merges separate tests for '**@all**',
'**@stream**' and '**@everyone**' stream wildcard mentions
into a single test named 'test_mention_stream_wildcard'.

Similarly, it merges separate tests for '@all', '@stream',
and '@everyone' stream wildcard mentions into a single test
named 'test_mention_at_stream_wildcard'.

The aim is to finally have two separate tests for stream and
topic wildcard mentions (when we introduce topic wildcards)
instead of having separate tests for each mention text
(i.e. all, everyone, stream, topic).

Prakhar Pratyush 2b42df4ef1 mention: Replace 'wildcard' with 'stream_wildcard'.
This is a prep commit to replace 'wildcard' with 'stream_wildcard'.

This wasn't included in 179d5cb because we didn't decide to
use a different rendered_content for topic wildcard mention,
i.e., ''<span class="user-mention topic-mention">{wildcard}</span>'.

Our intention was not to create separate tests for both stream
and topic wildcard mentions, as they were expected to have the
same rendered content format.

Prakhar Pratyush 179d5cb37d mention: Replace 'wildcards' with 'stream_wildcards'.
This prep commit replaces the 'wildcard' keyword in the codebase
with 'stream_wildcard' at some places for better readability, as
we plan to introduce 'topic_wildcards' as a part of the
'@topic mention' project.

Currently, 'wildcards = ["all", "everyone", "stream"]' which is an
alias to mention everyone in the stream, hence better renamed as
'stream_wildcards'.

Eventually, we will have:
'stream_wildcard' as an alias to mention everyone in the stream.
'topic_wildcard' as an alias to mention everyone in the topic.
'wildcard' refers to 'stream_wildcard' and 'topic_wildcard' as a whole.

Zixuan James Li 268f858f39 linkifier: Support URL templates for linkifiers.
This swaps out url_format_string from all of our APIs and replaces it
with url_template. Note that the documentation changes in the following
commits  will be squashed with this commit.

We change the "url_format" key to "url_template" for the
realm_linkifiers events in event_schema, along with updating
LinkifierDict. "url_template" is the name chosen to normalize
mixed usages of "url_format_string" and "url_format" throughout
the backend.

The markdown processor is updated to stop handling the format string
interpolation and delegate the task template expansion to the uri_template
library instead.

This change affects many test cases. We mostly just replace "%(name)s"
with "{name}", "url_format_string" with "url_template" to make sure that
they still pass. There are some test cases dedicated for testing "%"
escaping, which aren't relevant anymore and are subject to removal.
But for now we keep most of them as-is, and make sure that "%" is always
escaped since we do not use it for variable substitution any more.

Since url_format_string is not populated anymore, a migration is created
to remove this field entirely, and make url_template non-nullable since
we will always populate it. Note that it is possible to have
url_template being null after migration 0422 and before 0424, but
in practice, url_template will not be None after backfilling and the
backend now is always setting url_template.

With the removal of url_format_string, RealmFilter model will now be cleaned
with URL template checks, and the old checks for escapes are removed.

We also modified RealmFilter.clean to skip the validation when the
url_template is invalid. This avoids raising mulitple ValidationError's
when calling full_clean on a linkifier. But we might eventually want to
have a more centric approach to data validation instead of having
the same validation in both the clean method and the validator.

Fixes #23124.

"check_add_user_group" is a safer helper function than

error handling and notify the client with the appropriate event.

Note that the populate_db command still uses "create_user_group"
because we do not need to enqueue events at that point.
