If the text part of an email message didn't specify the charset in the
Content-Type header, the text content wouldn't be found. We fix this, by
assuming us-ascii charset in those cases, as specified by RFC6657:
https://tools.ietf.org/html/rfc6657
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.
Currently there's no way to tell the difference between "a server admin
deactivated a realm due to it being spammy" vs "a realm admin deactivated
the realm".
Due to my misreading the code and a sloppy search, I thought in
8218bf101c that
all_stream_subscription_logs didn't filter for streams.
While changing this, we'll switch to using `.modified_stream_id` for
potentially better performance.
Fixes#12273.
When running the test_query_email_attr test in reverse, the test failed
because self._LDAPUser.attrs was being modified and it was being shared
with other tests.
This commit also removes the conditional for when a build status
does not have a corresponding emoji. In such a case, it is better
to have no emoji than displaying some boilerplate text about no
appropriate emoji being available.
This makes the implementation of `get_realm` consistent with its
declared return type of `Realm` rather than `Optional[Realm]`.
Fixes#12263.

This commit replaces the `create_stream_by_admins_only` setting with a
new `create_stream_policy` setting, which mirroring the structure of
the existing `invite_to_stream_policy`.
This is important preparation for migrating the waiting period feature
to be its own independent setting.
Fixes#12236.
Running the backend tests with a high number of processes can cause
unexpected errors with language changes. When certain tests that change
the default language, (without explicitly overriding the teardown method
to reset the default language), interleave with other tests that are
expecting the language to be in English, discrepancies arise.
This fixes a common nondeterministic test failure with high levels of
parallelization.
If a soft deactivated user had a subscription double-toggled without
any new messages being sent in between, add_missing_messages might
incorrectly process those two subscription changes in the wrong order.
Fortunately, the failure mode was usually to throw this exception:
django.db.utils.IntegrityError: duplicate key value violates unique
constraint "zerver_usermessage_user_profile_id_message_id_4936d0df_uniq"
DETAIL: Key (user_profile_id, message_id)=(4, 57) already exists.
Our unit tests actually had this precise setup some fraction of the
time, because a bit of the test setup code subscribed+unsubscribed the
target user without sending any messages in between, resulting in a
test failure something like 50% of the time.
The original exception was hard to reproduce reliably originally
(resulting in an extremely annoying nondetermnistic test failure), but
is easily reproducible by changing the "id" to "-id" in this change to
always mis-order the processing of those RealmAuditLog events.
Previously, our soft-deactivation logic incorrectly did not filter the
set of stream subscription changes to look at to only include the
target stream.
This could result in unspecified buggy behavior.
Break will do the same thing as continue here, as each iteration will
have the same result, and it's also worth explaining why this isn't
one layer up in the loop setup.
Using sys.exit in a management command makes it impossible
to unit test the code in question. The correct approach to do the same
thing in Django management commands is to raise CommandError.

We should definitely be starting each test case with an empty copy of
the per-request caches, since their intended duration is even shorter
than a request.
This was masked by the fact that these caches are automatically
flushed when one makes an actual request to the Zulip API; so the
problems were only manifesting in tests like test_events, where we
call lower-level functions that access a per-request cache without
using the Zulip API.
The make_import_output_dir helper function used a path determined
primarily by the filename of the fixture being used, and expected to
have complete control over that path for the duration of the test.
This resulted in nondeterministic errors if our two test classes that
ran Mattermost import code ran at the same time.
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`.
This is useful when syncing avatars from an integrated LDAP/active
directory.
The upload avatar and delete avatar buttons are hidden if avatar
changes are disabled and the user is a non-admin.
If the user has a gravatar set, then the user will not be able to
upload an image as their avatar if avatar changes are disabled.
Part of #12132.
This module is used to render the HTML of pages like our user documentation
into text for use in open graph previews of those articles. It provided somewhat
confusing output in the case that there were paragraph breaks in the original message,
because text with multiple paragraphs and list items does't read very well. This commit
adds `|` as a delimiter between paragraphs, and prefixes list items with a `*`.
Closes#12228
When an emoji is nested inside another inline tag - like em or strong -
it was getting double processed because of the way the inlinePattern
TreeProcessor runs (it runs recursively). With this fix, we set the
inner text of the emoji span as an AtomicString, preventing us from
double processing the emoji's text.
Fixes#11621
Test Plan:
* Add test case for **😄**, verify it passes.
* Go into local dev server and send "**😄**" to self and verify the DOM
does not have double <span> tags for the emoji.
* Run zerver.tests.test_push_notifications and verify the markdown test case matches
the text_content field properly
comment_created payloads may not contain the required issue data
to format a useful notification, therefore, it is better to handle
issue comments through issue_updated events (which we already do).
Fixes: #11995.
We create rate_limit_entity as a general rate-limiting function for
RateLimitedObjects, from code that was possible to abstract away from
rate_limit_user and that will be used for other kinds of rate limiting.
We make rate_limit_user use this new general framework from now.
This enables the function to either return a valid UserProfile or raise
InvalidMirrorInput, which is clearer and more pythonic than the previous
approach of a tuple of a bool and Optional[UserProfile].
In making the type clearer, this improves checking with mypy.
Tests updated.
This commit creates a new organization setting that determines whether
a user can invite other users to streams. Previously this was linked
to the waiting period threshold, but this was both not documented and
overly limiting.
With significant tweaks by tabbott to change the database model to not
involve two threshhold fields, edit the tests, etc.
This requires follow-up work to make the create stream policy setting
work how this code implies it should.
Fixes#12042.
Allow realms to specify the day of the week when the digest should be sent out.
When enqueue-ing digests, pick only the realms that chose the current weekday as
the day to send out digests.
The github-services model for how GitHub would send requests to this
legacy integration is no longer available since earlier in 2019.
Removing this integration also allows us to finally remove
authenticated_api_view, the legacy authentication model from 2013 that
had been used for this integration (and other features long since
upgraded).
A few functions that were used by the Beanstalk webhook are moved into
that webhook's implementation directly.
An endpoint was created in zerver/views. Basic rate-limiting was
implemented using RealmAuditLog. The idea here is to simply log each
export event as a realm_exported event. The number of events
occurring in the time delta is checked to ensure that the weekly
limit is not exceeded.
The event is published to the 'deferred_work' queue processor to
prevent the export process from being killed after 60s.
Upon completion of the export the realm admin(s) are notified.
This slows down the tests by about 5-10% -- the tests go from 0.6s to 0.630s or
so. But, this seems like a change worth making to prevent open-graph metadata
breaking HTML.
The entire idea of doing this operation with unchecked string
replacement in a middleware class is in my opinion extremely
ill-conceived, but this fixes the most pressing problem with it
generating invalid HTML.

The initial goal was to improve message formatting and punctuation
but after a closer look, I realized that a larger refactor was
worth it for clarity and redability.
This reverts commit fd9dd51d16 (#1815).
The issue described does not exist in Python 3, where urllib.parse now
_only_ accepts (Unicode) str and does the right thing with it. The
workaround was not being triggered and would have failed if it were.

This contains email of the user to whom notification is being
send. This has not been used in any past mobile releases, so it is
safe to remove it.
As user_id will be stable for the user, but not email. So it's better to
start consuming `user_id` instead of email on mobile.
Calls to `render_markdown_path` weren't getting cached since the context
argument is unhashable, and the `ignore_unhashable_lru_cache` decorator ignores
such calls. This commit adds a couple of more decorators - one which converts
dict arguments to the function to a dict items tuple, and another which converts
dict items tuple arguments back to dicts. These two decorators used along with
the `ignore_unhashable_lru_cache` decorator ensure that the calls to
`render_markdown_path` with the context dict argument are also cached.
The time to run zerver.tests.test_urls.PublicURLTest.test_public_urls drops by

This fixes an issue where the hanging unordered list was not
rendering in blockquote; the problem was that we were not
adding an empty line(to satisfy the markdown) for hanging
unordered list if it is in blockquote. Both blockquote
and code block is fenced but we want to avoid rendering
the list if it's in the code block but not in blockquote.
Fixes: #11916.
This commit serves as the first step in supporting "public export" as a
webapp feature. The refactoring was done as a means to allow calling
the export logic from elsewhere in the codebase.
This is important because upcoming features will include slightly more
complex logic in post_process_state that we'd ideally like to be
included in what this suite tests.
This requires a few related changes:
* A small change to post_process_state to sort the realm_users objects
by user_id to ensure those data structures are stable.
* Improvements to the logic for checking if the initial state has
changed to use match_states for better output.
Extend the list of users that have to be notified when a message is
changed, so that in addition to users who have a UserMessage row, any
users who subscribed later to a stream with history public to
subscribers will also get the update.
Fixes: #8750.
This adds experimental support in /register for sending key
statistical data on the last 1000 private messages that the user is a
participant in. Because it's experimental, we require developers to
request it explicitly in production (we don't use these data yet in
the webapp, and it likely carries some perf cost).
We expect this to be extremely helpful in initializing the mobile app
user experience for showing recent private message conversations.
See the code comments, but this has been heavily optimized to be very
efficient and do all the filtering work at the database layer so that
we minimize network transit with the database.
Fixes#11944.
Certain payloads for account updates do not include the
previous_attributes that allow us to figure out what was actually
updated. So, we just ignore just payloads.
This is in response to a support ticket where the user had a closed left
sidebar, had added an organization, and then couldn't figure out how to
switch organizations. They had googled and found "The desktop app makes it
easy to switch between different organizations" in our help docs, which was
not sufficiently helpful.
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.
Previously, we could 500 if an organization administrator scanned
possible PreregistrationUser IDs looking for a valid invitation they
can interact with.
They couldn't do anything, so no security issue, but this fixes that
case to just be a 400 error as it should be.
With the previous commit, fixes#1836.
As specified in the issue above, we make
get_email_gateway_message_string_from_address raise an exception if
it doesn't recognise the email gateway address pattern. Then, we make
appropriate adjustments in the codepaths which call this function.
These functions don't really belong in actions.py, so we move them out,
into email_mirror_helpers.py. They can't go directly into
email_mirror.py or we'd get circular imports resulting in ImportError.
The hope is that by having a shorter list of initial streams, it'll
avoid some potential confusion confusion about the value of topics.
At the very least, having 5 streams each with 1 topic was not a good
way to introduce Zulip.
This commit minimizes changes to the message content in
`send_initial_realm_messages` to keep the diff readable. Future commits will
reshape the content.
There were several problems with the old format:
* The sender was not necessarily the sender; it was the person who did
the deletion (which could be an organization administrator)
* It didn't include the ID of the sender, just the email address.
* It didn't include the recipient ID, instead having a semi-malformed
recipient_type_id under the weird name recipient_user_ids.
Since nothing was relying on the old behavior, we can just fix the
event structure.
We change the send_to_email_mirror management command, to send messages
to the email mirror through the mirror_email_message function instead of
process_message - this makes the message follow a similar codepath as
emails sent into the mirror with the postfix configuration, which means
going through the MirrorWorker queue. The reason for this is to make
this command useful for testing the new email mirror rate limiter.
Closes#2420
We add rate limiting (max X emails withing Y seconds per realm) to the
email mirror. By creating RateLimitedRealmMirror class, inheriting from
RateLimitedObject, and rate_limit_mirror_by_realm function, following a
mechanism used by rate_limit_user, we're able to have this
implementation mostly rely on the already existing, and proven over
time, rate_limiter.py code. The rules are configurable in settings.py in
RATE_LIMITING_MIRROR_REALM_RULES, analogically to RATE_LIMITING_RULES.
Rate limit verification happens in the MirrorWorker in
queue_processors.py. We don't rate limit missed message emails, as due
to using one time addresses, they're not a spam threat.
test_mirror_worker is adapted to the altered MirrorWorker code and a new
test - test_mirror_worker_rate_limiting is added in test_queue_worker.py
to provide coverage for these changes.
We clean up test_mirror_worker for more readability, as well as make it
verify that mirror_email gets called the correct amount of times and use
a correct rcpt_to address, so that the test doesn't fail when some
verification of the address is added in the following commits
implementing rate limiting in the email mirror.
Fixes#9840.
Old addresses caused bugs in some cases with non-latin characters in
stream names (see issue number above). We switch to using django's
slugify helper function to convert stream names to full ascii, while
also getting rid of problematic non-alphanumeric characters, in a
reasonable way. See Django's documentation for slugify to see more about
how this function works.
Tests extended by tabbott to cover cases where we do end up with ascii.
To prepare for changing how the stream name gets encoded into mirror
email addresses while making sure old addresses keep working, we ignore
the stream_name part when receiving emails into the mirror and we only
look at the email_token to identify into which stream to mirror the
email.
I'm surprised that this wasn't a mypy error; we were passing a Realm
object as an integer, and predictably, this resulted in us
constructing a cache key that looked like this:
stream_by_realm_and_name:<Realm: zulip 1>:dd5...
Previously, these cache keys looked like:
:1:9c26164d3a393e316e0f8210efe270e08710d45astream_by_realm_and_name:...
Now, they look like this:
:1:9c26164d3a393e316e0f8210efe270e08710d45a:stream_by_realm_and_name:...
This avoids a bunch of duplicated calls to auth_enabled_helper for our
social auth backends, which added up because auth_enabled_helper can
take 100us to run.
