There are three functional side effects:
• Correct an insignificant but mathematically offensive bias toward
repeated characters in generate_api_key introduced in commit
47b4283c4b4c70ecde4d3c8de871c90ee2506d87; its entropy is increased
from 190.52864 bits to 190.53428 bits.
• Use the base32 alphabet in confirmation.models.generate_key; its
entropy is reduced from 124.07820 bits to the documented 120 bits, but
now it uses 1 syscall instead of 24.
• Use the base32 alphabet in get_bigbluebutton_url; its entropy is
reduced from 51.69925 bits to 50 bits, but now it uses 1 syscall
instead of 10.
(The base32 alphabet is A-Z 2-7. We could probably replace all of
these with plain secrets.token_urlsafe, since I expect most callers
can handle the full urlsafe_b64 alphabet A-Z a-z 0-9 - _ without
problems.)

There is still some miscellaneous cleanup that
has to happen for things like analytics queries
and dead code in node tests, but this should
remove the main use of pointers in the backend.
(We will also still need to drop the DB field.)
In 5200598a31, we introduced a new
client capability that can be used to avoid unreasonable network
bandwidth consumed sending avatar URLs of long term idle users in
organizations with 10,000s members.
This commit enables this feature and adds support for it to the web
client.
With this implementation of the feature of the automatic theme
detection, we make the following changes in the backend, frontend and
documentation.
This replaces the previous night_mode boolean with an enum, with the
default value being to use the prefers-color-scheme feature of the
operating system to determine which theme to use.
Fixes: #14451.

Fixes#15285
This event will be used more now for guest users when moving
topic between streams (See #15277). So, instead of deleting
messages in the topic as part of different events which is
very slow and a bad UX, we now handle the messages to delete in
bulk which is a much better UX.
This is designed to have no user-facing change unless the client
declares bulk_message_deletion in its client_capabilities.
Clients that do so will receive a single bulk event for bulk deletions
of messages within a single conversation (topic or PM thread).
Backend implementation of #15285.
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.

This was implemented in 2012 to avoid showing a loading indicator for
fetching messages for users with no message history. However, the
Zulip onboarding UI always creates some message history, and fetching
history is fast, so this is likely clutter more than a useful
optimization.
The pointer doesn't get updated when a user is only reading messages in
narrowed views. But, we use the pointer position to determine the
furthest read time, which causes the bankruptcy banner to show up even
for users who have been actively reading and sending messages.
This commit switches to using the time of the last update_message_flags
activity by a user to determine the time of last activity.
This page isn't polished properly and I'm not sure it's the best
decision tree here, but it's definitely better to have this page than
not, and we can always adjust forward.
Fixes#10033.
This reverts commit 8f32db81a1.
This change unfortunately requires an index that we don't have, and
thus is incredibly expensive. We'll need to do a thoughtful reworking
before we can integrate it again.
When a user is reading messages only in stream or topic narrows, the pointer
can be left far behind. Using this to compute the furthest_read_time causes
the banckruptcy banner to be shown even when a user has been actively
reading messages. This commit switches to using the sent time on the last
message that the user has read to compute the furthest read time.
Internet Explorer does not support `position: sticky` which improves
floating recipient bar behavior during scrolling which is one of the
issues blocking PR #9910.
IE also does not support some features that modern browsers support
hence may not super well.
This commit adds an error page that'll be displayed when a user logs
in from Internet Explorer. Also, a test is added.
This allows us to block use of the desktop app with insecure versions
(we simply fail to load the Zulip webapp at all, instead rendering an
error page).
For now we block only versions that are known to be both insecure and
not auto-updating, but we can easily adjust these parameters in the
future.
Users who are using ZulipDesktop or haven't managed to auto-update to
ZulipElectron should be strongly encouraged to upgrade.
We'll likely want to move to something even stricter that blocks
loading the app at all, but this is a good start.
This gives them cache-compatible URLs, and also avoids some extra
copies of the sprite sheet images.

This flag affects page_params and the
payload you get back from POSTs to this
url:
users/me/presence
The flag does not yet affect the
presence events that get sent to a
client.
In Django 2.0, request.user.is_authenticated stops supporting
`.is_authenticated()` and becomes just a property. In 1.11, it's a
CallableProperty (i.e. can be used either way), and we already use it
as a property in several other places, so we should just switch to
using it consistently now to get it off of our Django 2.x migration
checklist.
This extracts a function for computing show_invites and
show_add_streams, for better readability and testability.
This commit was substantially cleaned up by tabbott.
This legacy cross-realm bot hasn't been used in several years, as far
as I know. If we wanted to re-introduce it, I'd want to implement it
as an embedded bot using those common APIs, rather than the totally
custom hacky code used for it that involves unnecessary queue workers
and similar details.
Fixes#13533.
Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013. We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not. Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.
While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.
This WebSockets code path had a lot of downsides/complexity,
including:
* The messy hack involving constructing an emulated request object to
hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
needs and must be provisioned independently from the rest of the
server).
* A duplicate check_send_receive_time Nagios test specific to
WebSockets.
* The requirement for users to have their firewalls/NATs allow
WebSocket connections, and a setting to disable them for networks
where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
been poorly maintained, and periodically throws random JavaScript
exceptions in our production environments without a deep enough
traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
server restart, and especially for large installations like
zulipchat.com, resulting in extra delay before messages can be sent
again.
As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients. We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.
If we later want WebSockets, we’ll likely want to just use Django
Channels.

With the server down, apply migrations 0245 and 0246. 0246 will remove
the pub_date column, so it's essential that the previous migrations
ran correctly to copy data before running this.
This sidesteps tricky escaping issues, and will make it easier to

Added a new button at the bottom of the stream list which redirects
users to '/#streams/all' where they can create new streams or subscribe
to new streams.
The button is not visible to guests.
Fixes#11642.
This commit migrates the Subscription's notification fields from a
BooleanField to a NullBooleanField where a value of None means to
inherit the value from user's profile.
Also includes a migrations to set the corresponding settings to None
if they match the user profile's values. This migration helps us in
getting rid of the weird "Apply to all" widget that we offered on
subscription settings page.
The mobile apps can't handle None appearing as the stream-level
notification settings, so for backwards-compatibility we arrange to
only send True/False to the mobile apps by applying those defaults
server-side. We introduce a notification_settings_null value within a
client_capabilities structure that newer versions of the mobile apps
can use to request the new model.
This mobile compatibility code is pretty effectively tested by the
existing test_events tests for the subscriptions subsystem.
If MAX_FILE_UPLOAD_SIZE is set to 0, then UI elements like the upload
icon in the compose and message edit UI and "Attachments" menu in
"/#settings" are not displayed.
A different error message is also displayed if a user tries to drag and
drop or paste a file into the compose message box.
Fixes#12152.
Fixes#12251.
Previously when disabling name changes in server settings, instead
of realm settings, the name edit button did not get disabled.
Changing name resulted in a message stating `no changes made`.
Fixes#12132.
Realm setting to disable avatar changes is already present.
The `AVATAR_CHANGES_DISABLED` setting now follows the same
2-setting model as `NAME_CHANGES_DISABLED`.
Previously, we had some expensive-to-calculate keys in
zulip_default_context, especially around enabled authentication
backends, which in total were a significant contributor to the
performance of various logged-out pages. Now, these keys are only
computed for the login/registration pages where they are needed.
This is a moderate performance optimization for the loading time of
many logged-out pages.
Closes#11929.
The night logo synchronization on the settings page was perfect, but
the actual display logic had a few problems:
* We were including the realm_logo in context_processors, even though
it is only used in home.py.
* We used different variable names for the templating in navbar.html
than anywhere else the codebase.
* The behavior that the night logo would default to the day logo if
only one was uploaded was not correctly implemented for the navbar
position, either in the synchronization for updates code or the
logic in the navbar.html templates.
Add all the stop words to page_params, reading from the
`zulip_english.stop` database, with caching to avoid loading the file
on every page load.
Part of #10592.
Since we have already added the `invite_as` field to models, we can now
replace usage of `invite_as_admin` properly with its equivalent `invite_as
== PreregistrationUser.INVITE_AS['REALM_ADMIN']`.
Hence, also removed now redundant `invite_as`.
If `TEXT_EMOJISET` is currently selected emojiset then fallback to
`GOOGLE_EMOJISET` for displaying emojis in emoji picker and
composebox typeahead. We should pre-load the spritesheets in`emoji.js`
even in case of text emojiset otherwise on slow networks emoji picker
will appear empty initially.
This setting isn't intended to exist long term, but instead to make it
possible to merge our search pills code before we're ready to cut over
production environments to use it.
We now have a simple algorithm: First, look at the URL path
(e.g. /de/, which is intended to be an override). Second, look at the
language the user has specified in their settings.
We haven't seen significant traffic from the legacy desktop app in
over a year, and users using it get a warning to upgrade since last
summer, so it's probably OK to stop providing special fonts for it.
The handlebars error message is just for the manual development
environment; this prevents the state of compiling handlebars templates
from run-dev.py from potentially causing the unit tests to fail.
This should make it easier to find the templates that are actually
part of the core webapp, instead of having them all mixed together
with the portico pages.
