The original/legacy emoji reactions endpoints made use of HTTP PUT and
didn't have an API that could correctly handle situations where the
emoji names change over time. We stopped using the legacy endpoints
some time ago, so we can remove them now.
This requires straightforward updates to older tests that were still
written against the legacy API.
Fixes#12940.
The function only used the user's realm anyway, so this is a cleaner
API.
This should also make it more convenient to permanently delete
messages manually, since one doesn't have to fetch a random user in
the realm in order to delete a message using the management shell.
No functional change.
This fixes two regressions in 1946692f9a.
The first bug was actually introduced much earlier, namely that we
were not sending a `bot_owner_id` field at all for bot users without
an owner. The correct behavior would have been send `None` for the
owner field.
The second bug was simply that we needed to update the webapp to look
for the `bot_owner_id` field, rather than an old email-address format
`bot_owner` field.
Thanks to Vinit Singh for reporting this bug.
The state of the FAKELDAP setup for the dev env has fallen behind the
backend changes and updates to fakeldap (which implemented
SCOPE_ONELEVEL searches), as well as having some other minor issues.
This commit restore it to a working state and now all three config modes
work properly.
This makes it possible to simlulate messages sent by specific clients,
rather than just "test suite". Relevant for sending messages where
`message.sent_by_human()` is True.
Rather than subtracting sets in multiple places, it's simpler/cleaner
to just check which users are in the set when processing them.
This refactoring be helpful when we extend the get_recipient_info
logic to handle wildcard mentions as well.
django_to_ldap_username is now able to find the correct ldap username in
every supported type of configuration, so we can remove these
conditionals and use django_to_ldap_username in a straight-forward
manner.
Previously, we were using user_profile.email rather than
user_profile.delivery_email in all calculations involving Gravatar
URLs, which meant that all organizations with the new
EMAIL_ADDRESS_VISIBILITY_ADMINS setting enabled had useless gravatars
not based on the `user15@host.domain` type fake email addresses we
generate for the API to refer to users.
The fix is to convert these calculations to use the user's
delivery_email. Some refactoring is required to ensure the data is
passed through to the parts of the codebase that do the check;
fortunately, our automated tests of schemas are effective in verifying
that the new `sender_delivery_email` field isn't visible to the API.
Fixes#13369.
Apparently, the refactor months ago that introduced finalize_payload
wasn't applied to the outgoing webhook code path, resulting in message
dicts with an unexpected format with no avatar_url and some extra
values that were intended to be internal details not relevant to
external clients.
Because this API is not widely used, we expect there to be little to
no impact of converting this back to matching the `get_messages`
interface, as it once was and has always been intended to be.
The one somewhat tricky detail is that we include both the `content`
and `rendered_content` fields, rather than asking the client to pick
which they want via the `apply_markdown` flag, because there is no
place for the client to configure that setting.
The code comment explains this issue in some detail, but essentially
in Kubernetes and Docker Swarm systems, the container overlayer
network has a relatively short TCP idle lifetime (about 15 minutes),
which can lead to it killing the connection between Tornado and
RabbitMQ.
We fix this by setting a TCP keepalive on that connection shorter than
15 minutes.
Fixes#10776.
Most of the failures were due to parameters that are not intended to
be used by third-party code, so the correct fix for those was the set
intentionally_undocumented=True.
Fixes#12969.
MigrationsTestCase is intentionally omitted from this, since migrations
tests are different in their nature and so whatever setUp()
ZulipTestCase may do in the future, MigrationsTestCase may not
necessarily want to replicate.
new_name and description params should be valid JSON
strings. The format of these params are marked as
json so that the curl example genenrator can convert
them into json strings.
This is a follow-up to b69213808a.
We now actually send messages from the notification_bot, which
is the real usecase for this code.
Also, this cleans up the code and removes needless asserts like
`assertNotEqual(zulip_realm, lear_realm)` making the test easier
to read.
A confirmation object is already created when
do_send_confirmation_email is called just above.
Tweaked by tabbott to remove an unnecessary somewhat hacky database
query.
Priviously, we rendered the topic links using the msg.sender.realm.
This resulted in issues with Zulip's internal bots not having access
to the realm_filters of the destination stream's realm. For example,
sending a message via the email gateway or notification would not
linkify any realm filters that a user would expect them to.
This limit was introduced in c588c79 as a part of the
feature and not due to performance crisis. So we are
increasing this limit to 7 days. Since topics tends to
naturally fizzle after day or two so 7 days limit
would be good enough.
Fixes#1727.
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.
Apparently, our change in b8a1050fc4 to
stop caching responses on API endpoints accidentally ended up
affecting uploaded files as well.
Fix this by explicitly setting a Cache-Control header in our Sendfile
responses, as well as changing our outer API caching code to only set
the never cache headers if the view function didn't explicitly specify
them itself.
This is not directly related to #13088, as that is a similar issue
with the S3 backend.
Thanks to Gert Burger for the report.
Previously, we were hardcoding the domain s3.amazonaws.com. Given
that we already have an interface for configuring the host in
/etc/zulip/boto.cfg (which in turn, automatically configures boto), we
just need to actually use the value configured in boto for what S3
hostname to use.
We don't have tests for this new use case, in part because they're
likely annoying to write with `moto` and there hasn't been a huge
amount of demand for it. Since this doesn't regress existing S3
backend support, it seems worth merging.
This patches an issue in f37535044 where we mistakenly tried to send
the function as part of the page_params. Instead, we should just try
to send the list of configuration options (in their user displayable
form).
Apparently, the Zulip notifications (and resulting emails) were
correct, but the download links inside the Zulip UI were incorrectly
not including S3 prefix on the URL, making them not work.
While we're at this, we rewrite the somewhat convoluted previous
system for formatting the data export output.
This is also a useful preparatory refactor for having a user setting
controlling whether one's own email address is publicly available
within the organization.
We don't actually need to go to the memcached (falling back to the
database) to fetch either user or client objects on every event. For
user objects, we actually can just pass through the user ID
transparently; for client objects, we can use an in-process cache,
since the mapping of string to ID never changes.
This simple backwards-compatible change saves approximately 12% in the
compressed size of the chat.zulip.org page_params. We can do much,
much better by changing the format, but this seems like a good
intermediate step.

* Whitelist a small number of image/ types to be served as

It primarily affects servers using Zulip's local file uploads backend
for servers running Ubuntu 16.04 Xenial or newer; the legacy local
file upload backend for (now EOL) Ubuntu 14.04 Trusty was not affected
and it has limited impact for the S3 upload backend (which uses an
unprivileged S3 bucket domain to serve files).

This brings us in line, and also allows us to style these more like
unordered lists, which is visually more appealing.
On the backend, we now use the default list blockprocessor + sane list
extension of python-markdown to get proper list markup; on the
frontend, we mostly return to upstream's code as they have followed
CommonMark on this issue.
Using <ol> here necessarily removes the behaviour of not renumbering
on lists written like 3, 4, 7; hopefully users will be OK with the
change.
Fixes#12822.
We have a very useful piece of code, _RateLimitFilter, which is
designed to avoid sending us a billion error emails in the event that
a Zulip production server is down in a way that throws the same
exception a lot. The code uses memcached to ensure we send each
traceback roughly once per Zulip server per 10 minutes (or if
memcached is unavailable, at most 1/process/10 minutes, since we use
memcached to coordinate between processes)
However, if memcached is down, there is a logging.error call internal
to the Django/memcached setup that happens inside the cache.set() call,
and those aren't caught by the `except Exception` block around it.
This ends up resulting in infinite recursion, eventually leading to
Fatal Python error: Cannot recover from stack overflow., since this
handler is configured to run for logging.error in addition to
logging.exception.
We fix this using a thread-local variable to detect whether we are
being called recursively.
This change should prevent some nasty failure modes we've had in the
past where memcached being down resulted in infinite recursion
(resulting in extra resources being consumed by our error
notifications code, and most importantly, the error notifications not
being sent).
Fixes#12595.
There's no reason for this to be a category of error that emails the
server administrator, since there's a good chance that fixing it will
need to be done in the Zulip codebase, not administrator action.
Fixes#9401.
This adds a FAKE_EMAIL_DOMAIN setting, which should be used if
EXTERNAL_HOST is not a valid domain, and something else is needed to
form bot and dummy user emails (if email visibility is turned off).
It defaults to EXTERNAL_HOST.
get_fake_email_domain() should be used to get this value. It validates
that it's correctly set - that it can be used to form valid emails.
If it's not set correctly, an exception is raised. This is the right
approach, because it's undesirable to have the server seemingly
peacefully operating with that setting misconfigured, as that could
mask some hidden sneaky bugs due to UserProfiles with invalid emails,
which would blow up the moment some code that does validate the emails
is called.
Apparently, due to poor naming of the outer capture group we use to
separate the actual match from the surrounding whitespace (etc.) we
use to determine if the syntax is a possible linkifier start/end, if
you created a linkifier using "name" as the capture group, we'd try to
compile a pattern with two capture groups called "name", which would
500, preventing anyone from accessing the organization.
Historically, Zulip's implementation of wildcard mentions never
triggered either email or push notifications, instead being limited to
desktop notifications and the "mentions" counter.
We fix this just by plumbing the "wildcard_mentioned" flag through our
system.
Implements much of
https://github.com/zulip/zulip/issues/6040#issuecomment-510157264.
We're also now ready to seriously work on #3750.
After a new user joins an active organization, it isn't obvious what
to do next; this change causes there to be recent unread messages in
the stream sidebar for the user to click on to get a feel for what's
happening in the organization and experiment with Zulip.
Fixes#6512.
This commit wraps up the major work that we held back when upgrading
py-markdown 2.6.11 to 3.0.1. Since we were making our custom changes
to the link syntax, at the time we stuck to using the old method of
parsing links. This lays the groundwork for further changes to our
link and image link handling, and brings us on par with upstream.
Also, we now better document the ways in which our link handling is
different from upstream.
Previously, the unread_msgs data structure accounting (used for both
the web and mobile apps to determine the "Unread mentions" count
displayed in the UI) did not include wildcard mentions at all.
We fix this by adding the logic required to include properly that
data, with tests. As discussed in #6040, it makes sense to include
muted streams and topics for the purpose of this calculation.
Fixes part of #6040.
Apparently, get_active_presence_idle_user_ids, which is carefully
optimized to only fetch data for users who might actually need
notification processing, was only considering PMs and direct mentions,
not wildcard mentions or alert words.
This caused some pretty weird failure modes when working on adding
support for broader mention notifications, because users who had one
of these types of notifications would be treated as never
presence-idle, which was just confusing.
This is part of adding support for notifications for wildcard mentions
and alert words; it's worth merging this as an early commit because
the consequence of not doing this are very difficult to debug.
Add ability to search entire message history of all public streams at
once. It includes all subscibed, non subscribed public streams messages
and even historical public stream messages sent before user had joined
an organization or stream.
Fixes#8859.
Send the config_options for each supported incoming webhook bot along
with the initial state (not present in apply_events since this is
mostly just static data).
Without disturbing the flow of the existing code for configuring
embedded bots too much, we now use the config_options feature to
allow incoming webhook type bot to be configured via. the "/bots"
endpoint of the API.
This is a prep commit to allow us to validate user provided bot
config data using the same function for incoming webhook type
bots alongside embedded bots (as opposed to creating a new
function just for incoming webhook bots).
In integrations.py we have a class called Integration which we then usually
subclass and then use to define the meta-data for all of our integrations.
Now, we want to allow all of our bots, specifically incoming webhook bots,
to be configured (i.e. we should let the user provide BotConfigData).
For this we create a new instance member of the Integration class called
config_options which will be a list of tuples containing the displayable
integration name, the configuration key form of the integration name and
the validator that it's value is supposed to adhere to.
This was used as a helper to construct the final display_recipient when
fetching messages. With the new mechanism of constructing
display_recipient by fetching appropriate users/streams from the
database and cache, this shouldn't be needed anymore.
There is no need to fetch the entire Stream or UserProfile objects, as
only several fields are needed. We use Django's .values() method to only
get what's needed.
For UserProfiles, it means that we get from the queries are dictionaries
already in the display_recipient form (UserDisplayRecipient type) - so
we can remove the user_profile_to_display_recipient_dict function, as
there's no need for this UserProfile -> UserDisplayRecipient conversion
anymore.
Instead of having the rather unclear type Union[str,
List[UserDisplayRecipient]] where display_recipient of message dicts was
involved, we use DisplayRecipientT (renamed from DisplayRecipientCacheT
- since there wasn't much reason to have the word Cache in there), which
makes it clearer what is the actual nature of the objects and gets rid
of this pretty big type declaration.
Since the display_recipients dictionaries corresponding to users are
always dictionaries with keys email, full_name, short_name, id,
is_mirror_dummy - instead of using the overly general Dict[str, Any]
type, we can define a UserDisplayRecipient type,
using an appropriate TypedDict.
The type definitions are moved from display_recipient.py to types.py, so
that they can be imported in models.py.
Appropriate type adjustments are made in various places in the code
where we operate on display_recipients.
The user information in display_recipient in cached message_dicts
becomes outdated if the information is changed in any way.
In particular, since we don't have a way to find all the message
objects that might contain PMs after an organization toggles the
setting to hide user email addresses from other users, we had a
situation where client might see inaccurate cached data from before
the transition for a period of up to hours.
We address this by using our generic_bulk_cached_fetch toolchain to
ensure we always are fetching display_recipient data from the database
(and/or a special recipient_id -> display_recipient cache, which we
can flush easily).
Fixes#12818.
