Renaming a user group to a name shared by other group wasn't a scenario
handled by the backend, and the server errored whenever this was
attempted.
Now a json_error is returned, letting the user know that a user group
with that name already exists.
The use_first_unread_anchor parameter allows automatically setting the
anchor to the first message that hasn't been read in this narrow.
Therefore it isn't necessary to specify an anchor when this parameter is
enabled.
Note from Tim: Arguably, we should think about making
`use_first_unread_anchor` the default behavior when anchor is
unspecified, but that's for later consideration.
We found out in #9953 that, appparently, loading the OpenAPI file was
taking abut a 5% of the Zulip server startup time.
Since in many cases (especially in development) having the file loaded
won't be necessary at all, we read it on the first time data from the
OpenAPI spec is needed.
Tweaked by tabbott to add a test.
Automatically detect if the OpenAPI spec file has been modified since
the last time it was loaded into memory, and if it has, automatically
reload it to have the latest version.
This feature is designed with development environments in mind. The main
benefit is being able to see the changes made to the OpenAPI document
without needing to restart the development server, which is tedious and
slows the documentation workflow down.
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.
This fixes a bug where administrators couldn't remove private
unsubscribed streams from the "default streams" list, because
access_stream_by_name didn't give them access to the stream object.
This commit adds 'resize_gif()' function which extracts each frame,
resize it and coalesces them again to form the resized GIF while
preserving the duration of the GIF. I read some stackoverflow
answers all of which were referring to BiggleZX's script
(https://gist.github.com/BigglesZX/4016539) for working with animated
GIF. I modified the script to fit to our usecase and did some manual
testing but the function was failing for some specific GIFs and was not
preserving the duration of animation. So I went ahead and read about
GIF format itself as well as PIL's `GifImagePlugin` code and came up
with this simple function which gets the worked done in a much cleaner
way. I tested this function on a number of GIF images from giphy.com
and it resized all of them correctly.
Fixes: #9945.
Email notifications for new logins displayed the login timestamp's
timezone in the location format (e.g. "Asia/Taipei"). Since that can
lead users to understand the login came from that place, the timezone in
those emails is now represented in +/-HHMM format.
Fixes#10178.
This flag is used to track which user/message pairs correspond to an
active mobile push notification, that should potentially be cleared
when the user reads the message.
This flag should never appear on a message that is also marked as
read; eventually we may want a cron job to check for that condition.
We include a partial index on UserMessage for this flag.
This adds a new function called handle_remove_push_notification in
zerver/lib/push_notifications.py which requires user_profile id and
the message id which has to be removed in the function.
For now, the function only supports GCM (and is mostly there for
prototyping).
The payload which is being delivered needs to contain the narrow
information and the content of the message.
This should make it much simpler for the mobile apps to line up the
data from server_settings against the data in the notifications.
Addresses part of #10094.
This ensures that the format of this data structures matches that for
in-realm bots in the main users data structure (including avatars,
etc.).
Fixes#10138.
For realms that don't have any presence-active users, we know for a
fact that there aren't any active clients that will be reloading just
after the server restarts, so we can skip filling the cache with data
related to that realm.
For zulipchat.com, this results in a significant performance
optimization for the recipient and stream caches, and a moderate
performance improvement for the user caches as well.
Private messages make up the bulk of Recipient objects. While private
messages are ~50% of messages, if you weight by messages received
(which is what is important for message-loading performance), it's
pretty strongly balanced towards stream messages.
We don't need to include long-term idle or other inactive users here,
since fetching them consumed to vast majority of the time.
(On chat.zulip.org, this decreased the runtime for populating the user
cache by 5x, removing only users we're unlikely to need to access).
This doesn't seem to have a huge performance downside (less than 1s
extra time for loading / on chat.zulip.org), and it means the
possibility of users having so many unreads that we get weird/buggy
behavior is much more unlikely to exist.
We'll still want a better experience for users who somehow go over
this limit, but it can be pretty firmly "you need to go mark some
things as read".
