Brainrecursion 30eaed0378 saml: Add option to restrict subdomain access based on SAML attributes.
Adds the ability to set a SAML attribute which contains a
list of subdomains the user is allowed to access. This allows a Zulip
server with multiple organizations to filter using SAML attributes
which organization each user can access.

Cleaned up and adapted by Mateusz Mandera to fit our conventions and
needs more.

Rohitt Vashishtha 6ea3816fa6 markdown: Use html5 <time> tag for timestamps.
Previously, we had implemented:
    <span class="timestamp" data-timestamp="unix time">Original text</span>
The new syntax is:
    <time timestamp="ISO 8601 string">Original text</time>
    <span class="timestamp-error">Invalid time format: Original text</span>

Since python and JS interpretations of the ISO format are very
slightly different, we force both of them to drop milliseconds
and use 'Z' instead of '+00:00' to represent that the string is
in UTC. The resultant strings look like: 2011-04-11T10:20:30Z.

Fixes #15431.

Sara Gulotta 1cb040647b markdown: Add support for spoilers.
This adds support for a "spoiler" syntax in Zulip's markdown, which
can be used to hide content that one doesn't want to be immediately
visible without a click.

We use our own spoiler block syntax inspired by Zulip's existing quote
and math block markdown extensions, rather than requiring a token on
every line, as is present in some other markdown spoiler
implementations.

Fixes #5802.

Dinesh dc90d54b08 auth: Add Sign in with Apple support.
This implementation overrides some of PSA's internal backend
functions to handle `state` value with redis as the standard
way doesn't work because of apple sending required details
in the form of POST request.

Includes a mixin test class that'll be useful for testing
Native auth flow.

Thanks to Mateusz Mandera for the idea of using redis and
other important work on this.

Documentation rewritten by tabbott.

This reverts commit 7002f98ea1.

Rohitt Vashishtha 7002f98ea1 markdown: Process fenced code blocks in blockquotes.
We handle fenced code blocks in a preprocessor, and > style blockquotes
are parsed in a blockprocessor. Pymarkdown doesn't run the preprocessors
again on any blocks that it is parsing, and is unlikely to accept our
solution upstream; they intend to convert fenced_code to a block parser.

We simply run all the preprocessors on the text again, with the exception
of NormalizeWhitespace which removed delimiters used by HtmlStash to mark
preprocessed html code. To counter this, we subclass NormalizeWhitespace
and use our customized version for when it is called from a blockparser.

Upstream issue: https://github.com/Python-Markdown/markdown/issues/53

Fixes #12800.

Mateusz Mandera dac4a7a70b saml: Figure out the idp from SAMLResponse.
Instead of plumbing the idp to /complete/saml/ through redis, it's much
more natural to just figure it out from the SAMLResponse, because the
information is there.
This is also a preparatory step for adding IdP-initiated sign in, for
which it is important for /complete/saml/ to be able to figure out which
IdP the request is coming from.

Rohitt Vashishtha 52c25a9301 markdown-timestamp: Use data-timestamp attribute.
This commit shifts our timestamp syntax to be of the form:

Rohitt Vashishtha b062e8332f markdown: Add timestamp syntax to markdown processors.
This adds support for syntax like: !time(Jun 7 2017, 6:30 PM) so that
everyone sees the time in their own local timezone. This can be used
when scheduling online meetings, etc.

This adds some hardcoded values for timezones, because of there
being no sureshot way of determining the timezone easily. However,
since the main way of using the feature should be a typeahead for
entering the time, this shouldn't be cause of much concern.

Fixes #5176.

Rohitt Vashishtha 7d3a31cd8b bugdown: Support hanging_lists preprocessor for indented lists.
Previously, hanging_lists preprocessor didn't consider anything
indented at 4 or above spaces to be a list. This meant that when
we had a list like:

1. 1
  2. 2
    3. 3
  2. 2a
1. 1a

We would insert a newline between 3. 3 and 2. 2a. This resulted
in the block processor breaeking down 1 list into 2 blocks, which
messed up the nesting and indentation for the second block.

Tim Abbott e3a4aeeffa CVE-2020-9445: Remove unused and insecure modal_link feature.
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.

Rohitt Vashishtha ff5e2b6eb7 bugdown: Avoid hanging list paragraphs being processed as codeblocks.
Previously, the input:

====================
- One
  - Two

    Two continued

====================

This was because our CodeBlockProcessor had a higher priority than
the ListIndentProcessor. This issue was discussed here:

Rohitt Vashishtha 630c564fc7 bugdown: Rewrite List Preprocessor logic to properly parse fences.
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.

Rohitt Vashishtha 1229e69e9b bugdown: Reenable -,+ to begin a markdown list.
This commit has a side-effect that we also now allow mixed lists,

  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.

Thomas Ip 574c35c0b8 markdown: Render ordered lists using <ol> markup.
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.

Rohitt Vashishtha a7f2bedb15 markdown: Enable hashheadings syntax.

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.

okay 1694831029 bugdown: Fix double processed emoji tags inside inline tags.
When an emoji is nested inside another inline tag - like em or strong -
it was getting double processed because of the way the inlinePattern
TreeProcessor runs (it runs recursively). With this fix, we set the
inner text of the emoji span as an AtomicString, preventing us from
double processing the emoji's text.

Fixes #11621

Test Plan:

* Add test case for **😄**, verify it passes.
* Go into local dev server and send "**😄**" to self and verify the DOM
does not have double <span> tags for the emoji.
* Run zerver.tests.test_push_notifications and verify the markdown test case matches
the text_content field properly
