AlertWordNotificationProcessor to AlertWordsNotificationProcessor
to match the change from UserProfile.alert_words to Alertword.

This setting is being overridden by the frontend since the last
commit, and the security model is clearer and more robust if we don't
make it appear as though the markdown processor is handling this
issue.

Zulip's modal_link markdown feature has not been used since 2017; it
was a hack used for a 2013-era tutorial feature and was never used
outside that use case.
Unfortunately, it's sloppy implementation was exposed in the markdown
processor for all users, not just the tutorial use case.
More importantly, it was buggy, in that it did not validate the link
using the standard validation approach used by our other code
interacting with links.
The right solution is simply to remove it.
Previously, the input:
====================
- One
- Two
Two continued
====================
Would produce the same output as:
====================
- One
- Two
```
Two continued
```
====================
This was because our CodeBlockProcessor had a higher priority than
the ListIndentProcessor. This issue was discussed here:
https://chat.zulip.org/#narrow/stream/9-issues/topic/continuation.20paragraphs.20in.20list.20items.
webpack optimizes JSON modules using JSON.parse("{…}"), which is
faster than the normal JavaScript parser.
Update the backend to use emoji_codes.json too instead of the three
separate JSON files.

Previously, we didn't track opening and closing fences separately,
with led to bugs like not parsing a list that was immediately after
a quoted fence; we treated each ``` as a new fence.
This commit rewrites the function to maintain a stack of currently
open fences. If any of the parent fences is a code fence, we do not
insert a new line before a list.
We also add some test cases specifically to test this behavior with
complexly nested lists.
Fixes#13745.
In 3892a8afd8, we restructured the
system for managing uploaded files to a much cleaner model where we
just do parsing inside bugdown.
That new model had potentially buggy handling of cases around both
relative URLs and URLS starting with `realm.host`.
We address this by further rewriting the handling of attachments to
avoid regular expressions entirely, instead relying on urllib for
parsing, and having bugdown output `path_id` values, so that there's
no need for any conversions between formats outside bugdowm.
The check_attachment_reference_change function for processing message
updates is significantly simplified in the process.
The new check on the hostname has the side effect of requiring us to
fix some previously weird/buggy test data.

Previously, we would naively set has_attachment just by searching
the whole messages for strings like `/user_uploads/...`. We now
prevent running do_claim_attachments for messages that obviously
do not have an attachment in them that we previously ran.
For example: attachments in codeblocks or
attachments that otherwise do not match our link syntax.
The new implementation runs that check on only the urls that
bugdown determines should be rendered. We also refactor some
Attachment tests in test_messages to test this change.
The new method is:
1. Create a list of potential_attachment_urls in Bugdown while rendering.
2. Loop over this list in do_claim_attachments for the actual claiming.
For saving:
3. If we claimed an attachment, set message.has_attachment to True.
For updating:
3. If claimed_attachment != message.has_attachment: update has_attachment.
We do not modify the logic for 'unclaiming' attachments when editing.
add_a, add_oembed_data and add_embed are only called by
InlineInterestingLinksProcessor and this commit allows
these methods to access self.markdown object.
This commit has a side-effect that we also now allow mixed lists,
but they have different syntax from the commonmark implementation
and our marked output. For example, without the closing li tags:
Input Bugdown Marked
-------------------------------------
<ul>
- Hello <li>Hello <ul><li>Hello</ul>
+ World <li>World <ul><li>World
+ Again <li>Again <li>Again</ul>
* And <li>And <ul><li>And
* Again <li>Again <li>Again</ul>
</ul>
The bugdown render is in line with what a user in #13447 requests.
Fixes#13477.
We also switch the underlying exctact_mention_text method to use
a regular for loop, as well as make the related methods return
tuples of (names, is_wildcard). This abstraction is hidden from the
MentionData callers behind mention_data.message_has_wildcards().
Concerns #13430.
This brings us in line, and also allows us to style these more like
unordered lists, which is visually more appealing.
On the backend, we now use the default list blockprocessor + sane list
extension of python-markdown to get proper list markup; on the
frontend, we mostly return to upstream's code as they have followed
CommonMark on this issue.
Using <ol> here necessarily removes the behaviour of not renumbering
on lists written like 3, 4, 7; hopefully users will be OK with the
change.
Fixes#12822.
Apparently, due to poor naming of the outer capture group we use to
separate the actual match from the surrounding whitespace (etc.) we
use to determine if the syntax is a possible linkifier start/end, if
you created a linkifier using "name" as the capture group, we'd try to
compile a pattern with two capture groups called "name", which would
500, preventing anyone from accessing the organization.
This commit wraps up the major work that we held back when upgrading
py-markdown 2.6.11 to 3.0.1. Since we were making our custom changes
to the link syntax, at the time we stuck to using the old method of
parsing links. This lays the groundwork for further changes to our
link and image link handling, and brings us on par with upstream.
Also, we now better document the ways in which our link handling is
different from upstream.
This gives us access to typing_extensions.Deque, which was not added
to typing until 3.5.4.
(PROVISION_VERSION is not bumped because the transitive dependency set
in dev.txt hasn’t changed.)

Our implementation requires at least 1 space after the
'#' not not break existing linkifiers like '#123', etc.
that generally follow the convention we show in linkifier
examples.
- [valid] : # Hello
- [valid] : # Hello
- [invalid]: #Hello
For the frontend, we have taken the code from v0.7.0 of
upstream marked and made minor changes to avoid having
to refactor a significant part of our marked code.
For the backend, we merely have to change the regex to
force require spaces after #, and add hashheader to our
list of blockparsers.
Fixes#11418.
Django’s default FileSystemFinder disallows STATICFILES_DIRS from
containing STATIC_ROOT (by raising an ImproperlyConfigured exception),
because STATIC_ROOT is supposed to be the result of collecting all the
static files in the project, not one of the potentially many sources
of static files.

If a url doesn't have a scheme, browsers would treat it as a relative
url and open something like: https://chat.zulip.org/google.com instead.
This PR fixes the issue on the backend; the frontend implementation
remains out of sync and the user sending the message wouldn't see
any linkification for urls without a scheme.
Fixes#12791.
Modified by punchagan to:
* Replace URLs with titles only if the inline url embed previews are turned on
* Add a test for youtube titles replacing URLs
The titles for the videos are fetched asynchronously after the message has been
sent via the code that fetches metadata for open graph previews. So, the URLs
are replaced with titles only if the inline embed url previews feature is
enabled.
Ideally, YouTube previews should be shown only if inline url previews are
enabled, but this feature is in beta, while YouTube previews are pretty stable.
Once this feature is out of beta, YouTube previews should be shown only if the
url previews feature is turned on.
YouTube preview image is calculated as soon as the message is sent, while the
title needs to be fetched using a network request. This means that the URL is
replaced only after the data has been fetched from the request, and happens a
couple of seconds after the message has been rendered.
Closes#7549
Messages with links embedded in blockquotes turn out to be replies to
messages with links, more often than not. Showing previews for links in
replies seems like clutter, and it seems reasonable to turn off previews for
such links.
Modified by punchagan to:
* Add a separate markdown test for de-duplicating inline previews
* Check for number of unique URLs to see if per limit message is crossed
* Use a set for processed URLs instead of a list
Fixes#8379.
We reuse the link regexes we use elsewhere inn markdown
for parsing links in topic names and add a button to open
them in new tabs similar to our behavior with linkifiers
in topic names.
Fixes#12391.
Ensure that the html is safe, before using it. The html is considered if it is
in an iframe with a http/https src, based on the recommendations here:
https://oembed.com/#section3
We directly embed the `iframe` html into the lightbox overlay.
