This diff looks slightly noisy, but the main chunk of
code that we moved here has the same logic as before,
and it just gets realm_id from MentionBackend now, instead
of having our markdown processor have to supply it.
We basically want MentionData to be the gatekeeper of
mention data, and then we delegate backend tasks to
MentionBackend.
Soon we will add a cache to MentionBacked, which will
justify this change a bit more.
It's slightly annoying to plumb Optional[MentionBackend]
down the stack, but it's a one-time change.
I tried to make the cache code relatively unobtrusive
for the single-message use case.
We should be able to eliminate redundant stream queries
using similar techniques.
I considered caching at the level of rendering the message
itself, but this involves nearly as much plumbing, and
you have to account for the fact that several users on
your realm may have distinct default languages (French,
Spanish, Russian, etc.), so you would not eliminate as
many query hops. Also, if multiple streams were involved,
users would get slightly different messages based on
their prior subscriptions.
In many of our stream notification messages, we make use of the
same silent user mention syntax, the template for which was always
hardcoded. This commit adds a helper function that all relevant
callers can call to get the right syntax when mentioning users.
Thanks to Tim Abbott for this suggestion!
This commit adds related_name parameter to UserGroup.direct_members
such that we can use direct_groups instead of the default
usergroupmembership_set for getting all the groups of which the
user is direct member.
This commit also sets related_name of UserGroupMembership.user_group
and UserGroupMembership.user_profile to "+" which means that we will
not be having backward relations for these. This change is correct
since we would need to use the recursive queries to get all the
groups of a user and all the members of a group after we add the
subgroups concept in next commit. This leads to us using direct_members
field of UserGroup instead of usergroupmembership_set in mention code,
but this will soon be replaced with the recursive query function to
include subgroup's members as well.

We do not allow mentioning system user groups for now
because this can lead to circumventing the wildcard
mention restrictions. It will be enabled once we add
a setting to control that.
This is implemented by just ignoring it as one of the
mentioned user group even if the message content
inlcudes the mention syntax for it and the message
is sent normally.
We still keep the for_mention parameter for accessing
user group while sending email and push notifications
as mentioning system user groups will be allowed in
future.
This commit also removes the test for email notifications
for system user groups as we are not allowing mentioning
them.
This commit is only for backend change as we already
exclude the system groups from mention typeaheads and
other UI.
Prior to this, we only supported direct mention to
the user groups. This commit extends that support
to silent mention for the user groups.
A related test case is also added.
Fixes: #11711.
Earlier, USER_GROUP_MENTIONS_RE was:
r"(?<![^\s\'\"\(,:<])@(\*[^\*]+\*)"
For the syntax: *foo*, this was unnecessarily capturing it as
*foo* and the extraction of `foo` was done using another helper
function: `extract_user_group`.
This is now changed as:
r"(?<![^\s\'\"\(,:<])@(\*(?P<match>[^\*]+)\*)"
and extraction of `foo` can be done just by using the named capture
group `match`.
This change also helps to simplify its related code path.
Earlier, MENTIONS_RE was:
r"(?<![^\s\'\"\(,:<])@(?P<silent>_?)(?P<match>\*\*[^\*]+\*\*)"
For the syntax: **foo**, this was unnecessarily capturing it as
**foo** and adding extra operation for the extraction of `foo`.
This is now changed as:
r"(?<![^\s\'\"\(,:<])@(?P<silent>_?)(\*\*(?P<match>[^\*]+)\*\*)"
and extraction of `foo` can be done just by using the named capture
group `match`.
This change also helps to simplify its related code path.
Earlier wildcard mentions were used as: @all, @everyone, @stream.
This syntax is deprecated and we will no longer support
this syntax in future. See the commits:
1. 7a4c3c1a5c
2. b650b6b38c
When we started to use these syntaxes for wildcard mentions.
Following the convention, we use uppercase for
regex. Also, `user_group_mentions` is given a
conventional name ending with `*_RE`: `USER_GROUP_MENTIONS_RE`.
Fixes#2665.
Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.
Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start. I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

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.
Previous cleanups (mostly the removals of Python __future__ imports)
were done in a way that introduced leading newlines. Delete leading
newlines from all files, except static/assets/zulip-emoji/NOTICE,

These mentions look like regular mentions except they do not
trigger any notification for the person mentioned. These are
primarily to be used when you make a bot take an action and
the bot mentions you, or when you quote a message that mentions
you.
Fixes#11221.
This adds the data model and bugdown support for the new UserGroup
mention feature.
Before it'll be fully operational, we'll still need:
* A backend API for making these.
* A UI for interacting with that API.
* Typeahead on the frontend.
* CSS to make them look pretty and see who's in them.
It's unlikely to be of any real consequence, but this code bugged me
in that it makes a whole set before throwing it away to make nearly
the same set.
Sadly Python's comprehensions lack a way to write these cleanly as one
comprehension; but with no extra code complexity we can make the
temporary a genexp, which does the job.
We now triage message content for possible mentions before
going to the cache/DB to get name info. This will create an
extra data hop for messages with mentions, but it will save
a fairly expensive cache lookup for most messages. (This will
be especially helpful for large realms.)
[Note that we need a subsequent commit to actually make the speedup
happen here, since avatars also cause us to look up all users in
the realm.]
Given typeahed and the fact that this only worked if the person had a
full name that didn't contain whitespace, this side effect of the
original @shortname mentionfeature that we removed was experienced by
users as a bug.
Fixes#6142.
We want to avoid opening a DB connection in the markdown thread
as its DB connection might live for a long time
(imported from commit 7700b2ca793ee5e9add7f071b92f22a4bf576b3d)
This needs to be deployed to both staging and prod at the same
off-peak time (and the schema migration run).
At the time it is deployed, we need to make a few changes directly in
the database:
(1) UPDATE django_content_type set app_label='zerver' where app_label='zephyr';
(2) UPDATE south_migrationhistory set app_name='zerver' where app_name='zephyr';
