This is a fairly risky, invasive change that speeds up
stream deactivation by no longer sending subscription/remove
events for individual subscribers to all of the clients who
care about a stream. Instead, we let the client handle the
stream deactivation on a coarser level.
The back end changes here are pretty straightforward.
On the front end we handle stream deactivations by removing the
stream (as needed) from the streams sidebar and/or the stream
settings page. We also remove the stream from the internal data
structures.
There may be some edge cases where live updates don't handle
everything, such as if you are about to compose a message to a
stream that has been deactivated. These should be rare, as admins
generally deactivate streams that have been dormant, and they
should be recoverable either by getting proper error handling when
you try to send to the stream or via reload.
(There was a method with the same name before, but it wasn't
being used. The new version will accept stream_id instead
of name, and we will use it as part of deactivating streams.)
This fix prevents stream deactivation from being basically
un-usable for medium to large sites. Instead of calling
bulk_remove_subscriptions one at a time for every individual
member of the realm, we call it once for all the users that
care about the stream. This change makes a huge difference, but
the feature is still a bit clunky, and we should only temporarily
revert to this fix if future, more-invasive fixes have flaws.
Fixes#3631.
We were apparently incorrectly harcdoding the client for the main
logged-in site loading to website, rather than using the existing
logic that could sort out the desktop apps.
We already do detection of the client on the backend based on
User-Agent and the fact that it's a JSON view, which is pretty safe.
This fixes an issue where the server was not treating the Electron app
as its own client.
This significantly simplify the logic for our logging process, making
it the case that websockets message sending requests always are logged
as having the exact same client as a normal AJAX request from that
server.
This commit changes test_patch_bot_avatar to upload avatars to a
different directory so that there is no race condition when tests are
run in parallel mode.
This prevents users from either dragging formatted markup into content
editable boxes or pasting it in. This uses the “input” event rather
than “paste” because “paste” does not have the end result of the
contents whereas “input” does.
This is not a security vulnerability as it may seem. Processing on the
backend sanitizes input if it contains HTML.
We use to have client-side logic that would append timestamps
or random numbers to avatar URLs to force browsers to
refresh their cache.
We no longer need this now that the back end maintains
versions for avatar changes and puts the version in the URLs.
In some cases here we simplify things by calling avatar_url()
instead of get_avatar_url(), when we have a user_profile record
handy. For other cases we pass in an extra avatar_version
parameter to get_avatar_url(), including from avatar_url().
We have a field called user_profile.avatar_version that will
track avatar versions and be used tactically in avatar urls
to get browsers to refresh their caches (in future commits).
This commit bumps the avatar version when we update avatars.
We do this in do_change_avatar_fields(), which was
do_change_avatar_source() before this change.
Adarsh did the initial work here, and Steve Howell (showell) also
made changes.
To make all bots consistent add shared function in bot_lib.py
to check if this bot is called. All bots respond to at-mention of
the bot instead of their specific names.
