Hemanth V. Alluri e3aed0f7bc custom profile fields: Markdown rendering for custom profile field values.
This makes it possible it include our standard markdown formatting in
one's custom profile fields, allowing for links, emphasis, emoji, etc.

Fixes #10131.

Marco Burstein ba46dc83c6 notifications: Add a setting for changing the notification sound.
Also, add a new notification sound, "ding". It comes from
https://freesound.org, where the original Zulip notification sound comes
from as well. In the future, new sounds can be added by adding audio
files to the `static/audio/notification_sounds` directory.

Tweaked significantly by tabbott:
* Avoided removing static/audio/zulip.ogg, because that file is
  checked for by old versions of the desktop app.
* Added a views check for the sound being valid + tests.
* Added additional tests.
* Restructured the test_events test to be cleaner.
* Removed check_bool_or_string.
* Increased max length of notification_sound.
* Provide available_notification_sounds in events data set if global
  notifications settings are requested.

Fixes #8051.

Hemanth V. Alluri 6b1d724f5c zerver: Add bugdown rendering for text custom profile fields.
This is the first step of letting users use Zulip markdown in their
SHORT_TEXT and LONG_TEXT custom profile fields, so that they can
include emphasis, links, etc.

This doesn't include any frontend logic yet, however.

Tim Abbott ea1ec68899 events: Pass a realm object into send_event.
This is a preparator refactor for supporting hosting different Tornado
processes on different servers; to look up which Tornado server we
should be sending the event to, we'll need the realm object.

Steve Howell 551fc7f165 bots: Prevent bots from having duplicate full names.
Bots are not allowed to use the same name as
other users in the realm (either bot or human).

This is kind of a big commit, but I wanted to
combine the post/patch (aka add/edit) checks
into one commit, since it's a change in policy
that affects both codepaths.

A lot of the noise is in tests.  We had good
coverage on the previous code, including some places
like event testing where we were expediently
not bothering to use different names for
different bots in some longer tests.  And then
of course I test some new scenarios that are relevant
with the new policy.

There are two new functions:

    check_bot_name_available:
        very simple Django query

    check_change_bot_full_name:
        this diverges from the 3-line
        check_change_full_name, where the latter
        is still used for the "humans" use case

And then we just call those in appropriate places.

Note that there is still a loophole here
where you can get two bots with the same
name if you reactivate a bot named Fred
that was inactive when the second bot named
Fred was created.  Also, we don't attempt
to fix historical data.  So this commit
shouldn't be considered any kind of lockdown,
it's just meant to help people from
inadvertently creating two bots of the same
name where they don't intend to.  For more
context, we are continuing to allow two
human users in the same realm to have the
same full name, and our code should generally
be tolerant of that possibility.  (A good
example is our new mention syntax, which disambiguates
same-named people using ids.)

It's also worth noting that our web app client
doesn't try to scrub full_name from its payload in
situations where the user has actually only modified other
fields in the "Edit bot" UI.  Starting here
we just handle this on the server, since it's
easy to fix there, and even if we fixed it in the web
app, there's no guarantee that other clients won't be
just as brute force.  It wasn't exactly broken before,
but we'd needlessly write rows to audit tables.

Yashashvi Dave d5153bd136 events: Convert custom user field value to json object on update event.
In user type custom field, field value is list of user ids. We weren't
converting list to json object in update event payload. This throws
error in frontend, cause we store stringify representation of custom
field value. Therefore, after update event is recieved field-value-
type gets updated to array from string which throws json parsing error.

Tim Abbott c3c7b33351 tests: Move clear_client_event_queues_for_testing to ZulipTestCase.
Following recent testing flakes that were traced down to this not
having been called causing `receiver_is_off_zulip` to depend on test
ordering, it makes sense to centralize this.

I think it should always have been in ZulipTestCase; it appears the
reason it wasn't from the beginning was that originally only
test_events.py interacted with it, and do_test there still needs to
call this directly (because it can be called multiple times within a
single test).  And then we did the wrong thing as expanded use of
Tornado event_queue code in tests to more of the codebase.
2018-08-10 13:58:39 -07:00
Tim Abbott 93c12fad28 test_events: Use clear_event_queue_for_testing more systematically.

Yago González f6219745de users: Get all API keys via wrapper method.
Now reading API keys from a user is done with the get_api_key wrapper
method, rather than directly fetching it from the user object.

Also, every place where an action should be done for each API key is now
using get_all_api_keys. This method returns for the moment a single-item
list, containing the specified user's API key.

This commit is the first step towards allowing users have multiple API
keys.

Yashashvi Dave 290388e5e0 stream settings: Fix bug in UI when last user unsubscribe private stream.
When last user(only in case of admin) unsubscribe from private stream,
stream page doesn't get updated. Cause we delete the private stream
as soon as last user unsubscribe from stream.
So `sub` get undefined in frontend, cause that stream is deleted
before unsubscribe-user-from-stream event is received.

Fix this by changing order of events sent to frontend. Event
`subscription: remove` should be sent before `stream: delete` event
from backend.

Tim Abbott 1b2a26ca83 events: Fix missing empty custom profile data dict for new users.
We were getting event-handling exceptions in JS in production if a new
user was created and then went and set a custom profile field, because
there was no `.profile_data` on their user object.  We were able to
trace the issue down to the fact that our events didn't include that
field when creating a new user.

Aastha Gupta dfde4fac85 invitations: Send 'invites_changed' event for invitations events.
Fixes #7665

In case of invitation events, 'invites_changed' event without
any real payload is sent to all the realm admins and the user.
The event is handled by reloading the list to view recent changes.

Commit tweaked by shubhamdhama:
* Send an `invite_changed` event when an user accept an invite.
    Also, added the test for the same.
* No need to delete the invite list in frontend, current logic
    handles the case when the invite data is changed properly.
* Extracted the common logic for sending an event into
    `notify_invites_changed`.

Yashashvi Dave 649fccde6b zerver/lib/events.py: Fix custom field values not updated in apply_events.
Custom profile field value are stored in different structure compare to
other profile fields in events, so generic way to update fields wasn't
updating custom profile fields in `apply_event` function.

Fix this by adding check for custom fields in `apply_event`.

This also adds the appropriate test_events test to verify this code path.

Steve Howell 554883e039 submessages: Add submessage_id to submessage event.
It's useful to have the submessage_id so that widgets

on them arriving in sequence).
2018-05-30 14:47:36 -07:00
Steve Howell bfc13ecea4 submessages: Just send content for submessage events.
For some reason in my original version I was sending both
content and data to the client for submessage events,
where data === JSON.parse(content).  There's no reason
to not just let the client parse it, since the client
already does it for data that comes on the original
message, and since we might eventually have non-JSON
payloads.

The server still continues to validate that the payload
is JSON, and the client will blueslip if the server
regressses and sends bad JSON for some reason.

that it's easy as we refactor to separate the two concepts from things
like colors that are independent.

Steve Howell 431ede77c6 minor: Clean up how we set flags in events.
This is basically a simple fix, where we consistently set

`None`, which only showed up in the somewhat obscure circumstance
of somebody subscribing to all stream events in our API.

Greg Price 55cf54c087 upload: Remove old per-user quota feature.
We'll replace this primarily with per-realm quotas (plus the simple
per-file limit of settings.MAX_FILE_UPLOAD_SIZE, 25 MiB by default).

We do want per-user quotas too, but they'll need some more management
apparatus around them so an admin has a practical way to set them
differently for different users.  And the error handling in this
existing code is rather confused.  Just clear this feature out
entirely for now; then we'll build the per-realm version more cleanly,
and then we can later add back per-realm quotas modelled after that.

The migration to actually remove the field is in a subsequent commit.

This fixes a bug where, when a user is unsubscribed from a stream,
they might have unread messages on that stream leak.  While it might
seem to be a minor problem, it can cause significant problems for

Steve Howell ae5ba7f4fd Add a couple cross-realm bots.
These are new:

    new-user-bot
    emailgateway

Our cross-realm bots are hard coded to have email addresses
in the `zulip.com` domain, and they're not part of ordinary
realms.

These have always been cross-realm, but new enforcement in the
frontend code of all messages having been sent by a known user means
that it's important to add these properly.

This also introduces the GetUnreadMsgsTest class, and it fixes
the topic_name field that was accidentally hard coded in mute_topic.

Umair Khan 4c6a376fd5 user-groups: Add groups to page_params. 2017-11-09 17:35:46 -08:00
Steve Howell 8616a4ebc5 Use client_gratavar=True for users on in page_params.
This change affects realm_users and realm_non_active_users.

Note that we still send full avatar urls in realm_user/add
events, so apply_events has to do something mildly hacky to
turn the avatar_url to None in that case.

Fixing the event is probably not worth the trouble, as single
urls are not bandwidth hogs; we only need this optimization
for bulk data.

Steve Howell a076581426 Use client_gravatar=True for avatar URLs in page_params.
This change affects these values:

    * page_params.avatar_url
    * page_params.avatar_url_medium

It requires passing the client_gravatar flag through this
codepath:

    * home_real
    * do_events_register
    * fetch_initial_state_data
    * avatar_url

Steve Howell 2bbfda041a Support client_gravatar field for event registration.
This commit allows clients to register client_gravatar=True, and
then we recognize that flag for message events.  If the flag is
True, we will not calculate gravatar URLs and let the clients do
it themselves.  (Clients can calculate gravatar URLs based on
emails with just a little bit of code.)

Steve Howell 88e1e284bb Restructure send-message code for gravatars.
This refactoring doesn't change behavior, but it sets us up
to more easily handle a register setting for `client_gravatar`,
which will allow clients to tell us they're going to compute
their own gravatar URLs.

The `client_gravatar` flag already exists in our code, but it
is only used for Django views (users/messages) but not for
Zulip events.

The main change is to move the call to `set_sender_avatar` into
`finalize_payload`, which adds the boolean `client_gravatar`
parameter to that function.  And then we update various callers
to supply that flag.

One small performance benefit of this change is that we now
lazily compute the client message payloads in
`event_queue.process_message_event` now, so this will improve
performance if all interested clients have the same value of
`apply_markdown`.  But the change here is really preparing us
for the additional boolean parameter, which will cause us to
have four variations of the payload.
