Previously when system bots used to `#-mention` a private
channel's topics in cases like moving messages of a private
channel, then the #-mentions were not rendered by the
markdown. This was because the system bots did not have
authorization to mention these channels.
This is fixed by passing down an `acting_user` parameter
in code paths involving sending these move message
notifications so that permission of acting_user to mention
the topic is verified for rendering the markdown, rather
than that of the system bot.
This commit converts the links generated by the markdown
of the "#-mention" of topics to permalinks -- the links containing
the "with" narrow operator, the operand being the last message
of the channel and topic of the mention.
Fixes part of #21505
This commit adds support for empty string as a valid topic name
in syntax for linking to channel messages.
The server stores it after empty string is replaced with
`realm_empty_topic_display_name` and wrapped with an <em> tag.
The web client parses the rendered_content and updates
the topic_name part in the HTML with topic_name in user's language
+ wraps it in a <span> tag with 'empty-topic-display' css class.

`data-video-original-url` is duplicative with the `href` on the
surrounding `a` tag, which is never run through the Camo URL
translation. The `data-video-original-url` attribute was never
documented, and is not used by either mobile project, so is simply
removed.
If the content-type of the image is not in INLINE_MIME_TYPES, then we
do not expect browsers to be able to display it. This behaviour is
particularly confusing because the thumbnail will render properly,
since that will be in the more widely-supported WebP format, but the
lightbox will show a broken image.
In these cases, generate a high-resolution (4032x3024) "thumbnail"
which clients can choose to use instead. This thumbnail format is not
in the listed in the server's advertised thumbnail size list, because
it is not reliably generated for every image.
The transcoded thumbnail format is set on the `img` tag if it is
generated, and the original content-type is always passed to the
client, so it can decide how or if to render the original image. This
content-type is as the _original uploader_ specified it, so may be
incorrect.
The transcoded image is not animated, even if the original was. HEIC
files can nominally be animated, but in testing libvips was not able
to correctly recognize them as such. TIFF files are parsed as being
"animated," with one page per frame; this is of dubious utility, so
we merely transcode the first page. Always generating a static
transcoded image serves to also limit the computational time spent.
THUMBNAIL_OUTPUT_FORMATS is switched to be a tuple to ensure that it
is not accidentally mutated.
Previously, we do not allow mentioning system user groups
at all. Now we want to use silent mention syntax for system
groups in the message sent when updating the posting permission
for a stream, so it is important to allowing silent mentioning
system groups at least. And there is no problem in allowing
silent mentions of system groups for all users.
We do not allow mentioning system groups as can_mention_group
for them is set to "Nobody" group.
Microsoft has been renaming AzureAD to Entra ID. Though both names still
seem to function, even if unofficially, so this mostly renames to `Entra
ID (AzureAD)` to reference both for clarity.
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
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.

Document setting the keys that will send a message or create a new
line when composting a message via the compose box and via the
personal settings overlay.
Updates links and redirect from former help center article about
this feature.
Fixes#31620.
In order to only generate relative links for Zulip Cloud billing
specific gear menu options in relevant help center articles, we
pass down settings.CORPORATE_ENABLED to be set as a global variable
for zerver/lib/markdown/help_relative_links.py so that self-hosted
servers' help center documentation will not have these links.
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.
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).
Updates the instructions for `{settings_tab|invitations}` to work
like the deactivated users link, and updates the one article that
currently uses it: `help/invite-new-users.md`.
