Kislay Udbhav Verma 000cc7bcde markdown: Add support for a pretty syntax for message links.
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

Kislay Udbhav Verma 65c9b249b7 markdown: Refactor classes handling stream topic links.
The classes StreamPattern and StreamTopicPattern both had a
separate copy of the function `find_stream_id` which did the same
thing. Since another Pattern will be added as a part of #31920, it
is a good idea to move that function into a superclass which is then
inherited by all the related patterns.

Shubham Padia 2b3a41be58 user_card_popover: Show popover on all .messagebox user mention.
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.

Alex Vandiver 6f20c15ae9 thumbnail: Resolve a race condition when rendering messages.
Messages are rendered outside of a transaction, for performance
reasons, and then sent inside of one.  This opens thumbnailing up to a
race where the thumbnails have not yet been written when the message
is rendered, but the message has not been sent when thumbnailing
completes, causing `rewrite_thumbnailed_images` to be a no-op and the
message being left with a spinner which never resolves.

Explicitly lock and use he ImageAttachment data inside the
message-sending transaction, to rewrite the message content with the
latest information about the existing thumbnails.

Despite the thumbnailing worker taking a lock on Message rows to
update them, this does not lead to deadlocks -- the INSERT of the
Message rows happens in a transaction, ensuring that either the
message rending blocks the thumbnailing until the Message row is
created, or that the `rewrite_thumbnailed_images` and Message INSERT
waits until thumbnailing is complete (and updated no Message rows).

Alex Vandiver b7bf9e41c7 markdown: Catch urllib3 exceptions which are raised during streaming.
requests transforms the base urllib3 exceptions into
requests.RequestExceptions -- but only within code that it is
running.  When parsing the streaming body in fetch_open_graph_image,
the read itself (inside lxml) may trigger urllib3 to raise its own
timeout error -- which escapes the current catch of
requests.RequestExceptions.

Catch both requests and urllib3 exceptions.

Vector73 8ab526a25a models: Replace realm.uri with realm.url.
In #23380, we are changing all occurrences of uri with url in order to

replaced the occurences of uri that has no direct relation with realm.

This commit changes just the model property, which has no API
compatibility concerns.

Alex Vandiver 8c8dbb3d66 markdown: Stop attempting to expand/collapse re2 regex.
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.

Prakhar Pratyush 49388d5d3d topic_mentions: Fix restriction rule for @-topic mentions.
Now, the topic wildcard mention follows the following
rules:
* If the topic has less than 15 participants , anyone
can use @ topic mentions.
* For more than 15, the org setting 'wildcard_mention_policy'
determines who can use @ topic mentions.

Earlier, topic wildcard mentions followed the same restriction
as stream wildcard mentions, which was incorrect.

Alex Vandiver 091e2f177b linkifiers: Match JS implementation to server implementation.
Since the server-side implementation no longer uses look-ahead
or (more importantly) look-behind, it is possible to exactly implement
in Javascript.  This removes a common class which would prevent local
echo.

This requires reworking the topic linking algorithm, to march the
server's as well.  The tests and behaviour are adjusted in so doing --
previously, the JS implementation would have linked `#foo` with a
`foo` regex on the linkifier, but the server implementation would not
have.

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.

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.

breaking the intended display.

This change allows us to match the full emoji sequence, and
therefore show the correct image.
