We're renaming "stream deletion" language to "stream archiving"
and these pages were moved in the process, so we should keep redirects
for them for a while.
This reverts commit 9c6d8d9d81 (#16916).
This feature has known bugs, and also wants some design changes to
make it customizable like linkifiers, so we’re retargeting this to
post-4.x.

The Session middleware only adds `Vary: cookie` if it sees an access
to the from inside of it. Because we are effectively, from the Django
session middleware's point of view, returning the static content of
`request.saved_response` and never accessing the session, it does not
set `Vary: cookie` on longpoll requests.
Explicitly mark Tornado requests as varying by cookie.
Adding an additional `!` to the stream name each time a stream is
deactivated, to a maximum of 21 times, effectively limits number of
times a stream with a given name can be deactivated. This is unlikely
to come up in common usage, but may be confusing when testing.
Change what we prepend to deactivated stream names to something with
more entropy than just `!`, by instead prepending a substring of hash
of the stream's ID. `!`s. Using 128 bits of the hash means that it
will require more than 10^18th renames to have a 1% chance of collision.
Because too-long stream names are also truncated at 60 characters,
having this entropy in the beginning of the name also helps address
potential issues from stream names that differed only in, e.g. the
60th character.
Fixes#17016.
Instead of validating `op` value later, this commit does that
in `REQ`.
Also helps avoiding duplication of this validation when
stream typing notifications feature is added.
These flags were put in place in the first commit that introduced
Tornado (9afd63692f) with unclear
utility.
Remove them, since they have never been documented, and do not have a
clear need.
The `X-Forwarded-For` header is a list of proxies' IP addresses; each
proxy appends the remote address of the host it received its request
from to the list, as it passes the request down. A naïve parsing, as
SetRemoteAddrFromForwardedFor did, would thus interpret the first
address in the list as the client's IP.
However, clients can pass in arbitrary `X-Forwarded-For` headers,
which would allow them to spoof their IP address. `nginx`'s behavior
is to treat the addresses as untrusted unless they match an allowlist
of known proxies. By setting `real_ip_recursive on`, it also allows
this behavior to be applied repeatedly, moving from right to left down
the `X-Forwarded-For` list, stopping at the right-most that is
untrusted.
Rather than re-implement this logic in Django, pass the first
untrusted value that `nginx` computer down into Django via `X-Real-Ip`
header. This allows consistent IP addresses in logs between `nginx`
and Django.
Proxied calls into Tornado (which don't use UWSGI) already passed this
header, as Tornado logging respects it.
The `widget_content` key is expected to contain a string which parses
as JSON; in the event that it does not, log the error and notify the
bot owner, instead of failing silently.
Fixes#16850.
In `validate_account_and_subdomain` we check
if user's realm is not deactivated. In case
of failure of this check, we raise our standard
JsonableError. While this works well in most
cases but it creates difficulties in handling
of users with deactivated realms for non-browser
clients.
So we register a new REALM_DEACTIVATED error
code so that clients can distinguish if error
is because of deactivated account. Following
these changes `validate_account_and_subdomain`
raises RealmDeactivatedError if user's realm
is deactivated.
This error is also documented in
`/api/rest-error-handling`.
Testing: I have mostly relied on automated
backend tests to test this.
Fixes#17763.

Partially addresses issue #17763.
We add a TUTORIAL_ENABLED setting for self-hosters who want to
disable the tutorial entirely on their system. For this, the
default value (True) is placed in default_settings.py, which
can be overwritten by adding an entry in /etc/zulip/settings.py.
Updated database query to filter out deactivated streams from the
return of the get_topic_mutes method. Added optional
include_deactivated parameter to the method to make the behavior
default but overrideable. Added test case in test_muting for these
changes. Fixes blueslip warnings thrown by muting.js set_muted_topics
when passed deactivated streams via page_params.
With the previous two commits deployed, we're ready to use the
denormalization to optimize the query.
With dev environment db prepared using
./manage.py populate_db --extra-users=2000 --extra-streams=400
this takes the execution time of the query in
bulk_get_subscriber_user_ids from 1.5-1.6s to 0.4-0.5s on my machine.
The new comment explains the issue in some detail, but basically if we
deactivate the bots first, then an error partway through is corrected
by a retry; if we deactivate the user first, then we may leak
undeactivated bots if a failure occurs.
This adds the is_user_active with the appropriate code for setting the
value correctly in the future. In the following commit a migration to
backfill the value for existing Subscriptions will be added.
To ensure correct user_profile.is_active handling also in tests, we
replace all direct .is_active mutation with calls to appropriate
functions.
These procedures should be done atomically overall, with the exception
of the code that sends events to avoid block if there's a delay
communicating with Tornado.
We add the savepoint=False on underlying function that already
executes inside an atomic context - to avoid the overhead of creating
savepoints where they aren't needed.
This commit adds a new option of STREAM_POST_POLICY_MODERATORS
in stream_post_policy which will allow only realm admins and
moderators to post in that stream.
We extract a helper which checks whether to allow the sender to send the
message to a stream according to the stream_post_policy. The purpose
of extracting it out is to avoid additional code for checking the access
for bot owners in case of bot sending the messages and instead calling
the handler two times - one time for sender and one time for bot owner if
sender is a bot.
The moderators-only option was actually added in the previous
commit for create_stream_policy as we use the same function
'has_permission' for both the policies. But we add the error
handling code and tests for moderators-only option in this
commit.
This commit modifies the has_permission function to include
realm moderator role. Thus this adds a new option of moderators
only for create_stream_policy.
Though this automatically adds this option for invite_to_stream_policy
also, but we will keep other code for showing error and for tests
in a separate commit.
This commit adds an assert statement in the last block of
has_permission which checks whether the policy_value is
POLICY_FULL_MEMBERS_ONLY. This assert statement is added
for readability.
The current API documentation uses call_endpoint to upload a file;
since we've added a custom helper in python-zulip-api, we should
document that cleaner approach.
The session object provides a common place to set headers on all
requests, no matter which implementation.
Because the `headers` attribute of Session is not a true static
attribute, but rather exposed via overriding `__getstate__`, `mock`'s
autospec cannot know about it, and thus throws an error; in tests that
mock the Session, we thus must explicitly set the `session.headers`.
The existing organization, of returning an opaque blob from
`build_bot_request`, which was later consumed by
`send_data_to_server`, is not particularly sensible; the steps become
oddly split between the OutgoingWebhookWorker, `do_rest_call`, and the
`OutgoingWebhookServiceInterface`.
Make the `OutgoingWebhookServiceInterface` in charge of building,
making, and returning the request in one method; another method
handles extracting content from a successful response. `do_rest_call`
is responsible for calling both halves of this, and doing common error
handling.
The comments in stream-policy tests in test_message_send.py specifies
the restriction of creating streams based on stream_post_policy. But
this restriction was removed in 9aaa61963 and we now allow everyone to
create all type of streams. So this commit fixes the stream creation
parts in comments.
The STREAM_POST_POLICY_RESTRICT_NEW_MEMBERS option of stream_post_policy
was explained as "Only new members can post" in the api docs. It should
instead be "Only full members can post" and this commit fixes it.
The /events and /register endpoints were excluded from schema validations,
because they were earlier not completely documented. However, they can
now be added for proper checking. Removed them from excluded endpoints list
and fixed the documentation for /register and /events after the checking.
Fixes#17796.
Backend logic for handling user mention was cluttered
because it was handled at two stages first in
get_possible_mentions_info while fetching mention data
based on the messsage and then later in UserMentionPattern
which handles processing of text for mention.
Ideally UserMentionPattern should depend on
get_possible_mentions_info only for data but there was a
shared logic between these two that made it hard to debug
any possible bugs.
Updates in this commit make both of these functions
coherent in terms of logic and also add appropiate
comments to improve readability of these functions.
There was also a hidden bug that if a user A is
mentioned in with @**name|id** then @**invalid|id**
again mentioned A because of the way we handled mentions
earlier. It is solved as a result of this refactor and
appropiate test has been added for this.
This has been tested manually as well as by adding new
test to address missing case.
I noticed this because the test_events.py tests had the extremely
weird pattern of calling the actual change function, and then testing
the `notify` function's state changes (which should always be noops),
rather than actually testing the state change function.
Fixing the test made it clear that the actual logic in events.py
simply did not handle deleting custom_profile_field_value elements
from user objects when a custom_profile_field object was deleted.
So we fix that bit of logic as well.
It appears this bug was unique -- at least we don't have any other
notify_* functions being used directly in test_events.py, and the
handful of state_change_expected=False entries are all events for data
not present in page_params.
* `op` (operation) field, added in f6fb88549f, was never intended for
`custom_profile_fields` event. This commit removes the `op` as it doesn't
have any use in the code.
* As a part of cleanup, this also eliminates the schema check warnings
for `custom_profile_fields` event, mentioned in #17568.
In 1a12e112d9, this page was converted
to use portico styling, but we intentionally left this page not using
the portico_content class since we didn't want the header/footer.
We still don't want the header/footer clutter, so instead, we achieve
that same goal using the isolated_page flag.
When running some tests multiple times in the same call,
were failing because of the data duplication.
This commit resolves that issue by resetting the test
environment (i.e: Re-cloning test database and clearing
cache) after each run.
Fixes#17607.
Since the list of streams returned by a query which is not sorted
can vary, the tests which use it become flaky.
NormalActionsTest.test_default_stream_groups_events became
flaky due to this and hopefully sorting the streams should
fix it.
I have the updated the documentation page for the hello world
integration to include numbers to bring it up to standard and make it
more readable.
Fixes part of #17633.
This commit migrates some of the backend tests in test_import_export
to use assertLogs(), instead of mock.patch() as planned in #15331.
Logs for tests in this file are suppressed and are not asserted as
that made changes to import/export codebase more fragile. As we
already have checks for the actual functionalities, it made less
sense to assert those logs.
Currently, there was no markdown page for deactivate-own-user API
endpoint. Created deactivate-own-user.md for the API page and
created a new owner client in test-api to reactivate the client
deactivated during testing.
Also changed endpoint name from deactivate-my-account to
deactivate-own-user, for better consistency with other endpoints.
Fixes#16163.
This is no longer used in any important place,
get_user_profile_by_email is meant to be used only in manage.py shell
now and thus there's no point in this function being cached.
Emails are not unique, so we can only sensibly cache using keys formed
with both email and realm.
This requires adding a new cache key function for caching by delivery
email - user_profile_delivery_email_cache_key.
Extend our markdown system to support mentioning of users
by id also. Following these changes, it would be possible
to mention users with @**|user_id** and silently mention
using @_**|user_id**.
Main intention for extending the mention syntax is to make
it convenient for bots to mention a users using their ids. It
is to be noted that previous syntax are also supported.
Documentation tweaked by tabbott for better readability.
The changes were tested manually in development server, and also
by adding some new backend and frontend tests.
Fixes: #17487.
We add support to shorten links and test their shortening in
well-organized, clean manner that makes it trivial to extend the
GitHub approach for GitLab and perhaps other services.
We only shorten basic types of GitHub links (issue, PR, commit) that
fit a set of simple common patterns; the default behaviour of Autolink
is kept for everything else.
Logic added in frontend and backend Markdown Processor is identical.
This makes easy to extend the logic for other services like GitLab.
Fixes#11895.
The schema for unread_msgs was missing additionalProperties: false
that was causing tests to pass even with undocumented parameters
which were validated as an additional property. Set
additionalProperties to false and added documentation for missing
count variable.
Fixes#17728.
This commit changes the list_to_streams function to raise error
according to create_stream_policy value when a user cannot create
streams instead of same error for all cases.
This commit modifies test_user_settings_for_subscribing_other_users
to check all the possible cases including the cases when a user
can successfully subscribe other users along with the already
tested failure cases. This commit also adds checks for guest users
which was not present before.
This commit replaces the code which directly changes user.role,
realm.create_stream_policy and realm.waiting_period_threshold
with do_change_user_role and do_set_realm_property functions
in test_can_create_streams. This makes the code similar to the
other tests.
We refactor test_can_create_streams and test_can_subscribe_other_users
in test_subs.py. We want to follow a specific order in such tests
which is just set the policy value one by one and then checking
that the role in policy returns true and role just below that returns
false. This approach is explained in detail below.
Following hierarchy of roles is considered for these tests -
1. Realm admin
2. Full members
3. Members
4. Guests.
Then if the policy is set to admins only, we check that the having
role as admin returns true and the role just below that, i.e. full
member returns false. Similarly, if the policy is set to members
only, we check that a member should return true and role below it
which is guest should return false. We basically follow these as
we can assume that if a user with particular role cannot do the
required task, then user with role below in the hierarchy would
be not allowed to do the task too.
This commit refactors the above mentioned two tests to have above
explained workflow.
This commit removes the unnecessary do_change_user_role function
in test_can_subcribe_other_users. This was added in 1aebf3cab
which replaced the multiple functions like do_change_is_admin
and do_change_is_guest with do_change_user_role.
Previously two functions do_change_is_admin and do_change_is_guest
were used because there were two flags is_realm_admin and is_guest
which were used to determine the role of a user. But then we added
a single field role to UserProfile and removed the multiple flags
and thus also replaced the different functions with a single
do_change_user_role. With addition of a new field role, two
different do_change_* functions were not needed as we only have
a role field instead of different flags, but this was missed in
1aebf3cab and this commit fixes it.
This add the schema checker, openapi schema, and also a test for
realm/deactivated event.
With several block comments by tabbott explaining the logic behind our
behavior here.
Part of #17568.
We discovered recently that some ops for events were just not
implemented in events.py (specifically, realm/deactivated).
Since our goal is for events.py to be complete, we add this bit of
hardening to ensure that it stays that way.
Modifies `StreamPattern` and `StreamTopicPattern` to inherit
from InlineProcessor instead of Pattern. This change is done
because Pattern stopped checking for matching patterns as soon
as it found a match which was not a valid stream. Due to this
all the subsequent mention failed, even if they were valid.
This bug was only present in backend renderring due to
markdown.inlinepatterns.Pattern.
Due to above changes verbose_compile is no longer used for
precompiling STREAM_LINK_REGEX, STREAM_TOPIC_LINK_REGEX as
adds ^(.*?) and (.*?)$ which cause extra overhead of matching
pattern which is not required. With new InlineProcessor these
extra patterns at beggining and end are not required.
So, StreamPattern and StreamTopicPattern now define their own
__init__ method for precompiling the regex.
Fixes#17535.
These changes were tested locally in dev server and by adding
some new markdown tests to test these.
Modifies `UserGroupMentionPattern` to inherit from InlineProcessor
instead of Pattern. This change is done because Pattern
stopped checking for matching patterns as soon as it found
a match which was not a valid user group. Due to this all

valid. This bug was only present in backend renderring due to

This removes the `add` from op list of stream event, as we do not
actually generate the stream/add event in the API, and when a stream
is created we identify it using the `create` operation.
(This was likely just a mistake introduced as a result of the fact
that `create` does not fit the normal naming scheme; probably
long-term we should actually migrate this to "add", but more important
for now is to document what's accurate).

This is preparatory work for investigating reports of missing unread

This is a prep commit which modifies the
`send_message_moved_breadcrumbs` function to take
message strings as input.
This is done to reuse the function in other places
like the /digress command.
Structurally, exception, failure_message, and status_code are mutually
exclusive in how this function is called, and it's best for the
function's flow to represent that.
The message from the bot which triggered the 407 error message notifies
the bot owner about the exceptions as well in the error message. This
commit handles it more gracefully and shows a generic message.
The messages from the bot which were triggered by the outgoing_webhooks
didn't have the bot name in them. This commit adds the bot name to it
and makes the corresponding changes in the tests.
This adds an option for restricting a ldap user
to only be allowed to login into certain realms.
This is done by configuring an attribute mapping of "org_membership"
to an ldap attribute that will contain the list of subdomains the ldap
user is allowed to access. This is analogous to how it's done in SAML.

On replying to an email notifcation from a stream where the user
does not come under the stream_post_policy will subsequently result
in a failure. In such a case, the user does not receive feedback
regarding the failure.
Notify the user via notification bot if their email
message failed to send.
Fixes#16642.
If the client has an old version of the code which is not present on
the server, don't throw a 500; instead, default to the same `unable to
look up in source map` message is used when the line numbers don't
line up.
I have updated the documentation for the Zabbix integration to give the
correct instructions for the latest version of Zabbix (5.2). The old
instructions are now obsolete.
I have also updated the message that is PMd to a user if the webhook
doesn't receive a complete payload to also align with the new
instructions.
Using get_user_profile_by_email is invalid, as it omits the realm, and
also fetches via .delivery_email - our convention is that .email is
supposed to be used for user-facing purposes like this.
self.example_user("hamlet") uses get_user_by_delivery_email, so it
doesn't actually cache anything. This should use a cached function, like
the test below: test_do_change_realm_subdomain_clears_user_realm_cache.
This is part of our general process of replacing emails, which are not
static with time, with user_ids when referring to users in the API.
We still keep the `email` reference option, since it can be useful for
linking third-party applications to Zulip on an intranet that might
have a user's corporate email handy and not want to do the extra round
trip to lookup the user.
The name of the parameter, user_id_or_email, was chosen to to make it
clear that the default/preferred option is user_id.
Fixes#14304.
TextField is used to allow users to set long stream + topic narrow
names in the urls.
We currently restrict users to only set "all_messages" and
"recent_topics" as narrows.
This commit achieves 3 things:
* Removes recent topics as the default view which loads when
hash is empty.
* Loads default_view when hash is empty.
* Loads default_view on pressing escape key when it is unhandled by
other present UI elements.
NOTE: After this commit loading zulip with an empty hash will
automatically set hash to default_view. Ideally, we'd just display
the default view without a hash, but that involves extra complexity.
One exception is when user is trying to load an overlay directly,
i.e. zulip is loaded with an overlay hash. In this case,
we render recent topics is background irrespective of default_view.
We consider this last detail to be a bug not important enough to block
adding this setting.
The query string parameter authentication method is now deprecated for
newly created Slack applications since the 24th of February[1]. This
causes Slack imports to fail, claiming that the token has none of the
required scopes.
Two methods can be used to solve this problem: either include the
authentication token in the header of an HTTP GET request, or include
it in the body of an HTTP POST request. The former is preferred, as
the code was already written to use HTTP GET requests.
Change the way the parameters are passed to the "requests.get" method
calls, to pass the token via the `Authorization` header.

This commit updates the stream creation, subscribing others to
stream, wildcard mention settings and stream post policy to allow
realm moderators even if they are new and the respective setting
is set to allow full members only.
This commit renames the is_new_member property in models.py
to is_provisional_member which will return true for any user
who is not a full member. We will add a condition in further
commit such that this returns 'False' for a moderator as we
will initially give all the rights to moderator that a full
member has.
This was inaccurate after testing the implementation, and there's an
argument that we shouldn't move it as it will simplify migrating to a
world where (some) private message threads can have topics.
These are all referring to email_gateway_bot, when they're supposed to
refer to the notification and welcome bots, respectively. The values are
the same though, so the tests were passing anyway.
Its likely that we would implement new hotspots that aren't
a part of the tutorial hotspots, in the future. For instance,
a hotspot to advertise new features. Hence, grouping them into
categories like INTRO_HOTSPOTS would be a good start. We also
have an aggregate of all types of hotspots we may add in the
future, under ALL_HOTSPOTS.
Fixes#17238.
In process_new_human user, the queries were wrong, revoking all invites
sent to the email address, even in other realms than the one where the
new account just got created.
The description of request parameter of update-subscription-settings was
wrongly pasted in yaml and wasn't completely removed from the md file.
Made appropriate fixes in yaml and md file.
test_signup: This test was wrong, because the inviter UserProfile was
from a different realm. Such a PreregistrationUser shouldn't be
considered valid.
test_tutorial: The direct call to internal_send_private_message was
using sender's realm as the realm argument which is not valid. It
doesn't lead to any error because the codepath seems to mostly not care
about the realm arg if the sender is a cross-realm bot. From my reading
of the code I think that wrong realm arg here would break user mentions,
because it makes its way to check_message() and then to
build_message_send_dict - but overall the message gets sent without
errors. Either way, this was a bug in the test and should be fixed.
Currently, the ID and Type fields didn't have a description,
and weren't being displayed. Added a schema component to add
descriptions, and display on the api page. Fixes part of #15967.
This commmit includes ROLE_MODERATOR in realm_user_count_by_role.
We also update test_change_role in test_audit_log.py to include
changes for moderator role as well.
Note that at this point, it's not possible to create moderator users;
this just will make it easier to write tests for logic involving them
as we develop the feature.
Have not included "ROLE_MODERATOR" in UserProfile.ROLE_TYPES
in this commit because did not want to update the openapi
docs at this stage as it will be a user-facing change and
not updating the openapi docs with moderator role included in
UserProfile.ROLE_TYPES gives error in ./tools/check-schemas.
The `message_id` was made an `str` object because
the request expected `Dict[str, str]`. The request is now
casted to `Dict[str, Any]` to fix the issue and removed
typecast of `message_id` to str.

Currently there are only tests for verifying the error case and there
are no tests to check the case where messages are sent successfully
in 'STREAM_POST_POLICY_RESTRICT_NEW_MEMBERS' stream.
This commit adds tests for checking that full members and bots owned
by them can send message successfully in streams with post policy as
'STREAM_POST_POLICY_RESTRICT_NEW_MEMBERS'.
We currently not allow new bots to send message in stream with post
policy as 'STREAM_POST_POLICY_RESTRICT_NEW_MEMBERS', but we should
allow them to send messages if their owner is a full member.
This will make it consistent with behavior in stream with post
policy as 'STREAM_POST_POLICY_ADMINS_ONLY' where we allow non admin
bots with owner as admin to send messages.
According to tests we should not allow bot without owners to
post in streams with STREAM_POST_POLICY_RESTRICT_NEW_MEMBERS.
But the code does not handle this and the related test passes
and raises error for case of bots without owner because the bot
is itself a new member.
This commit fixes this by adding a condition to check if there
is no bot owner and then raise error if there is no owner.
This is a minor refactor which renames the
notify_topic_moved_streams function to
send_message_moved_breadcrumbs.
This is done because this function will be also used
for other things in the future, when moving streams
or when using the /digress command, for example.
Added assertion to check that if a deprecated flag is in a field's
schema, then it should have deprecated mentioned in description
as well, and moved these checks to a separate function.

A few internal fields used for tracking which types of notifications
have already been sent for a given message, like `hander_id` and the
`push_notified` bundle of fields were being incorrectly included in
message events delivered to clients clients.
One could argue these fields might be useful hints to clients, but
because notifications can be triggered later on via
`missedmessage_hook`, they have no useful purpose in the API.
This commit move these extended event field on a `internal_data`
object within the event object, and delete this field in `contents()`

Tweaked by tabbott to provide a cleaner interface.
We're not bumping API_FEATURE_LEVEL because these fields have always
been documented as being present only due to a bug, so no clients

Fixes: #15947.
user_profile.id was confused for user_profile.recipient_id. These bugs
are particularly sneaky as they can go undetected by tests due to ids of
objects accidentally coinciding. We add a mitigation for this class of
mistakes by shifting the Recipient.id sequence in test db.
This was introduced in dda3ff41e1.
On the rare occasion where user_profile.id would coincide with
recipient_id passed to the function, we would return the wrong value.
That is, instead of correctly returning recipient_id, we would return
sender.recipient_id - recipient id of the sender of the message, thus
possibly returning user_profile.recipient_id (if user_profile is the
sender) - exactly the situation the function wanted to avoid
with the `if recipient_id == my_recipient_id:` if. Ultimately resulting
in incorrect/malformed data in
state['raw_recent_private_conversations'].
nlargest is the natural fit for selecting n biggest items
from an unsorted list. It's more readable as well as more
efficent (even though we don't care much about the efficeny
in this particular case).
The current logic doesn't display data types when the additionalProperties
variables are not object, but are array of strings, etc. Changed the if
condition to allow rendering in such cases.
zerver/lib/users.py has a function named access_user_by_id, which is
used in /users views to fetch a user by it's id. Along with fetching
the user this function also does important validations regarding
checking of required permissions for fetching the target user.
In an attempt to solve the above problem this commit introduces
following changes:
1. Make all the parameters except user_profile, target_user_id
to be keyword only.
2. Use for_admin parameter instead of read_only.
3. Adds a documentary note to the function describing the reason for
changes along with recommended way to call this function in future.
4. Changes in views and tests to call this function in this changed
format.
Changes were tested using ./tools/test-backend.
Fixes#17111.
Previously, the data type of responses wasn't displayed in the API

The responses for the API weren't being rendered from yaml, and were
incorrectly formatted in yaml. The parameters also weren't completely
included in yaml and needed to be moved. Made appropriate fixes in

This commit migrates some of the backend tests to use assertLogs(),
instead of mock.patch() as planned in #15331.
Tweaked by tabbott to avoid tautological assertions.
There were some tests that had mock patches for logging, although no
logging was actually happening there. This commit removes such patches
in `corporate/tests/test_stripe.py`, `zerver/tests/test_cache.py`,
`zerver/tests/test_queue_worker.py`,
and `zerver/tests/test_signup.py`.
EmailLogBackend used to create a new EmailMessage and copy
only certain values from the original EmailMultiAlternatives
object. This resulted in the loss of information and made
it harder to test PRs like
https://github.com/zulip/zulip/pull/17121.
So instead of creating a new EmailMessage, tweak and send the existing
EmailMultiAlternatives object.
Depending on PostgreSQL’s query plan, it was possible for the value

The changes are as follows:
• Fix one day offset in all western zones.
• Correct CST from -64800 to -21600 and CDT from -68400 to -18000.
• Disambiguate PST in favor of -28000 over +28000.
• Add GMT, UTC, WET, previously excluded for being at offset 0.
• Add ACDT, AEDT, AKST, MET, MSK, NST, NZDT, PKT, which the previous
code did not find.
• Remove numbered abbreviations -12, …, +14, which are unnecessary.
• Remove MSD and PKST, which are no longer used.

When we were getting an apply_event call for
a subscription/add event, we were trying not to
mutate the event itself, but this clumsy code
was still mutating the actual event:
# Avoid letting 'subscribers' entries end up in the list
for i, sub in enumerate(event['subscriptions']):
event['subscriptions'][i] = \
copy.deepcopy(event['subscriptions'][i])
del event['subscriptions'][i]['subscribers']
This is only a theoretical bug.
The only person who receives a subscription/add
event is the current user.
And it wouldn't have affected the current user,
since the apply_event was correctly updating the
state, and we wouldn't actually deliver the event
to the client (because the whole point of apply_event
is to prevent us from having to piggyback the
super-recent events on to our payload or put
them into the event queue and possibly race).
The new code just cleanly makes a copy of each
sub, if necessary, as we add them to state["subscriptions"].
And I updated the event schemas to reflect that
subscribers is always present in subscription/add
event.
Long term we should probably avoid sending subscribers
on this event when the clients don't set something
like include_subscribers. That's a fairly complicated
fix that involves passing in flags to ClientDescriptor.
Alternatively, we could just say that our policy is
that we never send subscribers there, but we instead
use peer_add events. See issue #17089 for more
details.
It's always cleaner to work in id space. It probably
would have required a perfect storm to have broken
the existing code, but using ids is obviously more
robust in theory, and just as simple.
We now require keywords, so that there is no
pitfall for mixing up boolean parameters.
Positional parameters are basically evil
when you have a bunch of bools.
I also make user_profile the first argument.
Finally, the code is more diff-friendly.
I eliminate the defaults, since the existing code
was already specificying values for most things.
I move all the booleans to the bottom for both
parameters and arguments.
I require explicit keywords for everything but
user_profile (which is now first).
And, finally, I format the code in a more
diff-friendly manner.
We eliminate some redundant checks.
We also consistently provide a `subscribers` field
in our stream data with `[]`, even if our users
can't access subscribers. We therefore bump
the API version and tweak the docs. (See further
down for a detailed justification of the change.)
Even though it is sometimes fine to have redundant code
that is defensive in nature, some upcoming changes are gonna
move subscriber-related logic out of build_stream_dict_for_sub
for certain codepaths as part of our effort to streamline
the payload for subscribers within page_params.
So we can't rely on the code that I removed here
inside of build_stream_dict_for_sub.
Anyway, it makes more sense to do these checks explicitly
in the validate function.
The code in build_stream_dict_for_sub was almost effectively
a noop, since the validation function was already preventing
us from getting subscriber info. The only difference it
made was sometimes converting `[]` to `None`, and then
subsequently omitting the subscribers field.
Neither ZT nor the webapp make any distinction between
`[]` or <missing key> for the `subscribers` data in
`page_params`.
The webapp has had this code for a long time (and now
equivalent code elsewhere in this PR):
if (!Object.prototype.hasOwnProperty.call(sub, "subscribers")) {
sub.subscribers = new LazySet([]);
}
The webapp calculates access based on booleans, anyway:
sub.can_access_subscribers =
page_params.is_admin || sub.subscribed ||
(!page_params.is_guest && !sub.invite_only);
And ZT would choke if `subscribers` were missing, except that
it never gets to the relevant code due to other checks:
def get_other_subscribers_in_stream(<snip>):
assert stream_id is not None or stream_name is not None
if stream_id:
assert self.is_user_subscribed_to_stream(stream_id)
return [sub
for sub in self.stream_dict[stream_id]['subscribers']
if sub != self.user_id]
else:
return [sub
for _, stream in self.stream_dict.items()
for sub in stream['subscribers']
if stream['name'] == stream_name
if sub != self.user_id]
You could make a semantic argument that we should prefer
<missing key> to `[]` when subscribers aren't even available, but
we have precedent from the way that `bulk_get_subscriber_user_ids`
has traditionally populated its result:
result: Dict[int, List[int]] =
{stream["id"]: [] for stream in stream_dicts}
If we changed `stream_dicts` to `target_stream_dicts` we
would faciliate a move toward `None`, but it would just cause
headaches for other server code as well as the frontends
(which, to reiterate, already prefer the empty array
for convenience).
As my comment indicates, I would prefer to handle
this explicitly by raising JsonableError in an
else statement here, but it's not a big deal.
This function can probably be simplified with a
bit of work, mostly on the testing side to make
sure we are covering all edge cases, but that
is out of the scope of my current PR.
By moving the relevant logic from realm.get_bot_domain to
get_fake_email_domain we will make realm.host be used (if possible) for
dummy user addresses. That is, instead of user11@zulipchat.com, the
address will become user11@subdomain.zulipchat.com.
With the change in d70e1bcdb7,
bots get email like bot@zulip.com with EXTERNAL_HOST="zulip.com",
rather than bot@subdomain.zulip.com, which was the old format. That's
not desirable, so with this commit, realm.host will be used when
possible and only falling back to FAKE_EMAIL_DOMAIN if needed.
We often send only one field (away or status_text)
to be updated.
So we have to make our schema support optional
keys.
As a result of the more flexible schema, we no
longer need to exempt the node fixtures from
our schema checks.
Since recipient_id (id of the PERSONAL Recipient of the user) was
denormalized into the UserProfile model, this query can be simplified by
getting rid of the zerver_recipient JOIN.
This makes us more efficient when handling
multiple users. We don't have to keep
sending the same two queries to the database.
Note that as part of this we eliminated
a failure mode for the obscure population
of users from whom both `user.is_guest` and
`user.can_access_public_streams()` returns
False. We know this would have only affected
Zephyr users (by looking at the code), and
we know we don't actually process Zephyr
users for email digests (or else we would
have raised exceptions in the old code).
We mostly need realm_id, but when we go to build
message lists, we need realm.uri.
We could probably be more aggresive about using
`only` here, but for now I am just trying to
reduce hops to the database.
The `deployment` key was only set in `do_report_error`, which is now
only used in one codepath (the queue worker). The logging handlers on
staging call notify_server_error directly, which omits the
`deployment` key.
Remove the odd one-of key, and instead simply do dispatch in
`do_report_error`.
The codepath for moving a topic changes the message.recipient_id to the
id of the new recipient, but later, in update_messages_for_topic_edit,
it uses message.recipient when querying for messages with the matching
topic in the *old* stream (because those are the other messages that
need to be moved). This is a bug which happens to work fine, because in
Django 2, if message.recipient gets fetched first and then
message.recipient_id is mutated, message.recipient will not be altered
and thus will retain the outdated, previously fetched value.
In Django 3 changing .recipient_id causes .recipient to be updated to
the new Recipient objects, which is the Recipient of the *new* stream.
That will cause the bug to manifest.
This is a bugfix preparing for the upgrade to Django 3.
Support for saving it in the session is dropped in django3, the cookie
is the mechanism that needs to be used. The relevant i18n code doesn't
have access to the response objects and thus needs to delegate setting
the cookie to LocaleMiddleware.
Fixes the LocaleMiddleware point of #16030.
We now require explicit keywords for all arguments
to fetch_initial_state_data except user_profile.
We provide reasonable defaults to keep the test
code concise.
In the case of reusing a registration link, reuse the
redirect_to_email_login_url helper. This does have the side effect of
now showing a "you've already registered" note, which did not happen
previously, but that seems probably for the best, since the user did
just click a "register" link.
ecfafc05c0 shifted to using a different paramter name to hint that
the user had previously signed up -- and in so doing also stopped
pre-filling the "email" box. Also send along the email box, to save
users time.
Checking for `validate_email_not_already_in_realm` again (after the
form already did so), but only in the case that the form fails to
validate, means that we may be spending time pushing totally invalid
emails to the DB to check. In the case of emails containing nulls,
this can even trigger a 500 error from PostgreSQL.
Stop calling `validate_email_not_already_in_realm` in the form
validation. The form is currently only used in two places -- in
`accounts_home` and in `maybe_send_to_registration`. The latter is
only called if the address is known to not currently have an account,
so checking in there is unnecessary; and in the former case, we wish
different behaviour (the redirect) than just validation failure, which
is all the validator can do.

Add a `--allow-reserved-subdomain` flag which allows creation of
reserved keyword domains. This also always enforces that the domain
is not in use, which was removed in 0258d7d.
Fixes#16924.
When changing the subdomain of a realm, create a deactivated realm with
the old subdomain of the realm, and set its deactivated_redirect to the
new subdomain.
Doing this will help us to do the following:
- When a user visits the old subdomain of a realm, we can tell the user
that the realm has been moved.
- During the registration process, we can assure that the old subdomain
of the realm is not used to create a new realm.
If the subdomain is changed multiple times, the deactivated_redirect
fields of all the deactivated realms are updated to point to the new
uri.
Instead of just storing the edit history in the message which
triggered the topic edit, we store the edit history in all
the messages that changed. This helps users track the edit history
of a message more reliably.
This change updates the GitHub Integration webhook
get_opened_or_update_pull_request_body method so that
the description is only printed if it actually changes.
If the update event is a result of some other
attribute update, such as an asignee change, then the
description is not included in the message sent to
the zulip stream.

Allowing any admins to create arbitrary users is not ideal because it
can lead to abuse issues. We should require something stronger that
requires the server operator's approval and thus we add a new
can_create_users permission.
We change the return type of check_message to be dataclass instead of
Dict[str, Any]. This refactoring helps us to understand the context of the
data structure returned by check_message clearly which was not possible
when using Dict.
SendMessageRequest class is added in zerver/lib/message.py inspite of it
not being used in that file itself just to maintain consistency as other
TypedDicts and dataclasses are defined in that file and to avoid circular
dependency as SendMessageRequest is being used in lib/widget.py as well.
We also rename local variable to 'send_request' for accessing
SendMessageRequest objects.
The {addr} part isn't directly useful, since connections to Tornado
are done on localhost anyway, and made the development environment
output a bit more confusing.
Also, use the same phrasing for restarts we use for Django.
This logging is really only potentially interesting in a development
environment when the numbers are nonzero.
In production, it seems worth logging for consistency reasons.
Probably we'll eventually redo this block by change the log level, but
this is good enough to despam the development environment startup
output.
We always want to do these at the same time. Previously, message
editing did too much stripping (fixes#16837) and failed to check for

Previously we were just returning a dict containing a message id when
trying to mirror a already sent message in 'zephyr_mirror' cases.
This commit changes this behaviour to raise an exception when trying
to mirror an already sent message by adding a new exception class
ZephyrMessageAlreadySentException and then the caller returns the
message_id directly, instead of calling do_send_messages which also
returns a list of size one containing the message_id only.
This is a prep commit for changing the return type of check_message to
be a dataclass instead of a Dict as now we have only single output for
check_message.
This commit renames the content variable in do_widget_post_save_actions
to message_content and is a prep commit for changing the return type of
check_message from Dict to dataclass.
This change is required because content variable is used two times in
this function - one for message content and other for submessage
content, so when we change the return type of check_message to
dataclass, the type of content variable is considered as str and then
when dict is assigned to content in the submessage case, mypy raises
'Incompatible types in assignment' error.
This issue is not faced before the dataclass migration because there is
no type checking for the values of dict returned by check_message as the
return type of check_message is 'Dict[str, Any]'.
The message_dict['wildcard_mention_user_ids'] should be empty set instead
of empty list when there are no wildcard mentions similar to the case
when there are wildcard mentions, where it is equal to set of user ids and
not list of user ids.

If a user visits a realm which has been deactivated and it's

This simplifies the code, as it allows using the mechanism of converting

which uses a bigger unit(eg Dollar instead of Cents) as the standard.

For 3000 messages and 400 users, this saved
about 30 seconds.
We only do two queries per batch of messages
now, and the algorithm is easier to analyze,
as it's just three nested loops.
Note that we are much more efficient about finding
active users here:
- we do one query per realm (instead of per-user)
- we pass the cutoff date to the database
- we get back just a list of distinct ids
This function is going away completely soon. It is
querying everybody's entire UserActivity history instead
of passing the cutoff date to the database!
The query counts increase here for somewhat
contrived reasons. The tests before this
commit reflected a successful trip to the
UserProfile cache, but that's not actually
realistic in practice.
We don't need to mock the dates here. We also
explicitly clear out all streams first, and then
we explicitly test with both the stream being
current and the stream being old.
We can use the _enqueue_emails_for_realm helper
to avoid all the Tuesday-related logic here.
We also don't bother to create UserActivity
records, since the bot gets excluded by virtue
of its being a bot. (Also, the date ranges
here were sketchy due to the time mocking.)
We can avoid all the date mocking now for all
but a couple tests that exercise the is-it-Tuesday
logic.
And this test now correctly tests that we exclude
recently active users.
And this allows us to remove the other test.
Sentry allows adding simple webhooks without going through the process
of creating an Internal Integration in Sentry's Integration
Platform[1] (which our docs recommend).
The payload from sent from such a (simple) webhook integration is

This fixes a bug introduced in

was adjacent to the others that needed it in the file.
Fix this, and add tests to verify that things are still being escaped
once after removing this extra escape.
Fixes#14845.
The code we deleted here was no longer
doing anything.
Maybe the code was always dead, or maybe it
was written during a time when topics_by_diversity
and topics_by_length actually had different keys.
But now it's clearly cruft.
If we have 4 or more topics, then the code above
it would already have populated the list with 4
elements, and the `if num_convos < 4` condition
would evaluate to False.
And if we had 3 or fewer topics, then we would
have already put all possible topics into our
result, and the `topics_by_diversity[num_convos:4]`
slice would be empty.
It's possible that we should just have a simple
heuristic for topic hotness like `10*num_senders
+ messages`, so we don't have to maintain this
fiddly function, and we can just do something like
`topics_by_score[:4]`.
I now use sets for stream_ids in more of the digest
code.
As part of this I replaced exclude_subscription_modified_streams
with streams_recently_modified_for_user.
It's easier for the caller to just ask for ids
to delete from its callee than it is to pass
in a set/list to mutate.
The simpler boundary between the functions makes
the tests easier to write--you can see the
`filtered_streams` logic goes away in this diff.
I also make the tests a bit more thorough by using
combinations of Cordelia/Othello and Verona/Denmark
to try to find multiple possible flaws.
And I make the time intervals longer than 1s to
avoid false negatives from slow CI boxes.
If we have multiple users, this reduces the amount
of queries we need to do, because we get all
subscriptions for all users in a single query
to Subscription.
For the single-user case, we are introducing an
extra query hop, but the database is doing
roughly the same work, because we are just breaking
up this complex query into two hops:
messages =
select ... from message
where recipient__type_id in (
select stream_id from subscription
where ...
)
Now it's more like:
stream_ids =
select stream_id from subscription
where ...
messages =
select ... from message
where recipient__type_id in stream_ids
Note that we are not changing anything semantically
or algorithmically yet. The only overhead here
for the single-user case is boxing and unboxing
data into single-item dicts and lists.
The interfaces for callers in the view and the
queue processor remain the same for now.
We didn't need the enough-traffic mock.
We also continue to prep for testing multiple users.
I also finally remove a comment that is about to
be addressed (and which inaccurately refers to huddles).
This extraction will make a bit more sense when
we start doing bulk operations on a realm to
get digests, but even now, it encapsulates the
slightly complex way we cherry-pick the top 4
topics for a user.
This prep step is mostly for diff hygiene; the next
commit will make the code a bit nicer.
The original code here had the nice property that
most (but not all) of the DB work happened up
front in `handle_digest_email`, and none of the
DB work was delegated to the callers. But I
prefer the tradeoff of making the helpers a bit
more cohesive--let them get the data they need.
And we have query-count coverage in our tests,
so there's no real danger of having helpers
down in the stack insidiously doing a bunch of
extra DB hops.
In 709493cd75 (Feb 2017)
I added code to render_markdown that re-fetched the
sender of the message, to detect whether the message is
a bot.
It's better to just let the ORM fetch this. The
message object should already have sender.
The diff makes it look like we are saving round trips
to the database, which is true in some cases. For
the main message-send codepath, though, we are only
saving a trip to memcached, since the middleware
will have put our sender's user object into the
cache. The test_message_send test calls internally
to check_send_stream_message, so it was actually
hitting the database in render_markdown (prior to
my change).
Before this change we were clearing the cache on
every SQL usage.
The code to do this was added in February 2017
in 6db4879f9c.
Now we clear the cache just one time, but before
the action/request under test.
Tests that want to count queries with a warm
cache now specify keep_cache_warm=True. Those
tests were particularly flawed before this change.
In general, the old code both over-counted and
under-counted queries.
It under-counted SQL usage for requests that were
able to pull some data out of a warm cache before
they did any SQL. Typically this would have bypassed
the initial query to get UserProfile, so you
will see several off-by-one fixes.
The old code over-counted SQL usage to the extent
that it's a rather extreme assumption that during
an action itself, the entries that you put into
the cache will get thrown away. And that's essentially
what the prior code simulated.
Now, it's still bad if an action keeps hitting the
cache for no reason, but it's not as bad as hitting
the database. There doesn't appear to be any evidence
of us doing something silly like fetching the same
data from the cache in a loop, but there are
opportunities to prevent second or third round
trips to the cache for the same object, if we
can re-structure the code so that the same caller
doesn't have two callees get the same data.
Note that for invites, we have some cache hits
that are due to the nature of how we serialize
data to our queue processor--we generally just
serialize ids, and then re-fetch objects when
we pop them off the queue.
The passwords generated for our development environment / test suite
include the `+` character, which needs to be quoted when encoded as an
HTTP POST parameter.
This is hopefully sufficient to fix the CI failures we've seen with
the tests for POST /api/v1/fetch_api_key; I haven't reproduced the
failure so am not completely sure.
Steve asked me to remove this, since the tictactoe game was always
intended as a proof of concept. Now that we have poll and todo
widgets, the sample code for tictactoe has much less value.
We replace the content and type in test_widgets.py to maintain
coverage.
This reverts commit 564b199fe6, which
was part of #16308.
Escaping is either required or incorrect; it is never “defensive”.
This escaping is incorrect. lxml already escapes attributes during
serialization (any other behavior would be a serious bug), and
additional escaping just results in double escaping.

Initally, when writing two or more quotes, having
a blank line in between them, merges those quotes.
This created confusion especially in "quote and reply".
This commit fixes such issues. Now two or more quotes
having a blank line in between them, will not get merged.
This change is correct both for usability and for improving our
compatibility with CommonMark.
Fixes#14379.
By registering a post_delete handler to clear appropriate caches in a
nicer way, we can get rid of the ugly flush-memcached call in the
delete_realm command.
This commit adds migration which removes default status of exisitng
default private streams, i.e. private stream exists but they are no
longer default.
