Zulip's previous model for managing static asset files via Django
pipeline had some broken behavior around upgrades. In particular, it
was for some reason storing the information as to which static files
should be used in a memcached cache that was shared between different
deployments of Zulip. This means that during the upgrade process,
some clients might be served a version of the static assets that does
not correspond to the server they were connected to.
We've replaced that model with using ManifestStaticFilesStorage, which
instead allows each Zulip deployment directory to have its own
complete copy of the mapping of files to static assets, as it should
be.
We have to do a little bit of hackery with the staticfiles.json path
to make this work, basically because Django expects staticfiles.json
to be under STATIC_ROOT (aka the path nginx is serving to users), but
doing that doesn't really make sense for Zulip, since that directory
is shared between different deployments.
In a Zulip production environment, STATIC_ROOT points to the shared
directory that static assets are served from, and so the
compilemessages management command was trying to process every
historical version in there.
We do not use `get_link_embed_data` for messsages sent by
bots, as bots often repeat the same URL over and over again
and are generally either text-focused or have their own
mechanisms to provide preview content.
Fixes#2968.
(The commit q7ef4e40258280e202325c9295579c93fb948b replaced
data-user-email with data-user-id, but we still need to
support data-user-email for old clients like non-updated
androids and we still want to start the migration forward
to data-user-id.)
The goal of this library is to make it a lot easier to prevent bugs
like CVE-2017-0881 by having all of our views logic for fetching a
stream go through a couple carefully tested code paths.
A bug in Zulip's implementation of the "stream exists" endpoint meant
that any user of a Zulip server could subscribe to an invite-only
stream without needing to be invited by using the "autosubscribe"
argument.
Thanks to Rafid Aslam for discovering this issue.
Apparently, we weren't returning the `json_error`, resulting in users
encountering this condition receiving a 500, rather than the proper
40x error.
This fixes a regresion introduced in 9ae68ade8b.
Previously, if you searched for ':offi..' you would see both 🏢 and
:office_building: as possible completions, both of which are shortcodes for
the same unicode codepoint (and hence which have the same image). Also, we
sort the emoji in our emoji pickers alphabetically by shortcode, and so the
images for 🏢 and :office_building: show up next to each other, which
looks like a bug. This removes :office_building: as a shortcode, along with
several hundred other duplicates. It leaves some duplicates in that won't
give autocomplete or alphabetical ordering a problem, like (🚗,
:automobile:).
This fixes a regression introduced by our migration to track
subscribers for all public streams, where now users who are added to
an invite-only stream were receiving a mark_subscribed event
for a stream their browser didn't know existed, causing an exception.
To fix this, we now send a stream create event to the browser just
before the user receives the notification that it was added to the
invite-only stream.
The realm with string_id of "simple" just has three users
named alice, bob, and cindy for now. It is useful for testing
scenarios where realms don't have special zulip.com exception
handling.
In case realms have subdomains and the user hasn't been populated
yet in the Django User model, `ZulipLDAPAuthBackend` should not
rely on user's email domain to determine in which realm it should
be created in.
Fixes: #2227.
This fixes a bug where update_message_backend would do one memcached
query per user receiving a given message. Right now we just do a
single bulk database query, but in principle we could use
generic_bulk_cached_fetch to use the cache as well.
