We do not use `get_link_embed_data` for messsages sent by
bots, as bots often repeat the same URL over and over again
and are generally either text-focused or have their own
mechanisms to provide preview content.
Fixes#2968.
(The commit q7ef4e40258280e202325c9295579c93fb948b replaced
data-user-email with data-user-id, but we still need to
support data-user-email for old clients like non-updated
androids and we still want to start the migration forward
to data-user-id.)
This changes bugdown to use the realm passed in by the caller (if any)
for rendering, fixing a problem where bots such as the notification
bot would have their messages rendering using the admin realm's
settings, not the settings of the realm their messages are being sent
into.
Also adds a test for the notification bot case.
Fixes#3215.
A lot of care has been taken to ensure we're using the realm that the
message is being sent into, not the realm of the sender, to correctly
handle the logic for cross-realm bot users such as the notifications
bot.
This should substantially improve the clarity of the code, since
inside bugdown, this is only being used as a hash key that happens to
usually be a realm ID, not used as a Realm ID.
This change adds support for displaying inline open graph previews for
links posted into Zulip.
It is designed to interact correctly with message editing.
This adds the new settings.INLINE_URL_EMBED_PREVIEW setting to control
whether this feature is enabled.
By default, this setting is currently disabled, so that we can burn it
in for a bit before it impacts users more broadly.
Eventually, we may want to make this manageable via a (set of?)
per-realm settings. E.g. I can imagine a realm wanting to be able to
enable/disable it for certain URLs.
Now that we have updated python-markdown, we remove the deprecated
safe_mode. We used safe_mode to escape raw html, so now instead we
pass in an EscapeHtml markdown extension to the markdown engine.
See https://pythonhosted.org/Markdown/release-2.6.html for details on
the deprecation.
Fixes: #2037 (also addresses the remaining piece of #2043).
This distinguishes between YouTube Videos and Image Previews by adding
a particular “youtube-video” class to the preview along with changing
the title to the video ID rather than the link. This serves to allow
the lightbox to ID when a lightbox preview should be treated like a
YouTube video rather than an image preview.
This also modifies the tests in bug down to expect a youtube-video class
along with the title to just be the video ID on YouTube rather than the
entire URL link.
The changes that required us to fork this extension had been merged
into upstream CodeHilite, so we can remove it and switch to using the
version that comes with python-markdown.
This updates Bugdown to reflect the changes in the updated
markdown. In particular, we now pass a default config object in the
__init__ for the Bugdown extension, update the make_md_engine function
to take kwargs as opposed to a config list, and have UListProcessor
inherit from ulist as opposed to olist (which no longer works).
We update the (forked from upstream) fenced_code extension's
makeExtension to take args and kwargs, and update
FencedBlockPreprocessor __init__ method with updated Codehilite
arguments.
We update the (forked from upstream) Codehilite extension to
mirror the logic with the latest upstream Codehilite:
Add parse_hl_lines function
update makeExtension to take args and kwarfs instead of config
list
Add regex for highlight lines
use linenums instead of linenos
use get_formatter_by_name instead of HtmlFormatter
user get_lexer_by_name instead of TextLexer
add hl_lines and use_pygments arguments to the codehlite
constructor
Change the parameter name of some functions from 'md' to 'content',
since the name 'md' seems to be the reason why this parameter was
wrongly annotated.
This sets the “title” attribute on the image to the actual title of
the image specified by the user in their markdown, rather than just
the URL of the full link to it.
