User-supplied custom realm filter has had some sort of regex-based
validation of the format URL since their introduction in
d7e1e4a2c0 -- and this has always been
in addition to the URLValidator. The URLValidator is the one which
does the security-relevant work of validating that the schema is
reasonable, and that the overall shape of the URL is well-formed. The
regex has served primarily to arbitrary limit the characters that can
appear in the URL, in the mistaken name of safety.
Adjust the regex, such that its only purpose is to verify that the
usages of `%` characters in the URL are reasonable, and leave the URL
validation to the URLValidator, which can do a far better job. This
includes broadening the support to include `%%` as an escape
character; this is likely such a niche case as to be unnecessary, but
costs little.
Fixes#16013.
We don't yet have a do_reactivate_stream function, but we reserve a
number since:
1. It'll likely be added in the future.
2. For now, we can restore archived stream with some manual intervention
in the Django shell, and for that we'll want to create an appropriate
RealmAuditLog entry.
It is confusing to have the plan type constants not be namespaced
by the thing they represent. We already have a namespacing
convention in place for constants, so we should use it for
Realm.plan_type as well.
This commit adds related_name parameter to UserGroup.direct_members
such that we can use direct_groups instead of the default
usergroupmembership_set for getting all the groups of which the
user is direct member.
This commit also sets related_name of UserGroupMembership.user_group
and UserGroupMembership.user_profile to "+" which means that we will
not be having backward relations for these. This change is correct
since we would need to use the recursive queries to get all the
groups of a user and all the members of a group after we add the
subgroups concept in next commit. This leads to us using direct_members
field of UserGroup instead of usergroupmembership_set in mention code,
but this will soon be replaced with the recursive query function to
include subgroup's members as well.

This commit renames members field of UserGroup to direct_members
for better readability because in the new permissions model, a
user group can be a sub-group of another group and thus technically
members of sub-group will also be members of that group.
This is a prep commit for new permissions model.

This will be useful to let users enable/disable
sharing read receipts once we add that feature.
Note: Added "I've" to IGNORED_PHRASES in
tools/lib/capitalization.py to avoid capitalization
errors for the label text of this setting.
Note: These are not functional in enabling/disabling sending of
typing notifications with this commit.
Refactored the privacy settings update to keep the code less
duplicated along with making the addition of new settings easier.
This commit adds can_create_web_public_streams helper
in models.py which will be used to validate whether
user is allowed to create a web-public stream or not.
This commit also adds the checks for Realm.POLICY_OWNERS_ONLY
in check_has_permission_policies.
This commit adds create_web_public_stream_policy
field to Realm table which controls the roles that
can create web-public streams and by default its
value is set to POLICY_OWNERS_ONLY.
Zulip attempts to validate that the regular expressions that admins
enter for linkifiers are well-formatted, and only contain a specific
subset of regex grammar. The process of checking these
properties (via a regex!) can cause denial-of-service via
backtracking.
Furthermore, this validation itself does not prevent the creation of
linkifiers which themselves cause denial-of-service when they are
executed. As the validator accepts literally anything inside of a
`(?P<word>...)` block, any quadratic backtracking expression can be
hidden therein.
Switch user-provided linkifier patterns to be matched in the Markdown
processor by the `re2` library, which is guaranteed constant-time.
This somewhat limits the possible features of the regular
expression (notably, look-head and -behind, and back-references);
however, these features had never been advertised as working in the
context of linkifiers.
A migration removes any existing linkifiers which would not function
under re2, after printing them for posterity during the upgrade; they
are unlikely to be common, and are impossible to fix automatically.
The denial-of-service in the linkifier validator was discovered by
@erik-krogh and @yoff, as GHSL-2021-118.
Users wanted a feature where they could specify
which users can create public streams and which users can
create private streams.
This splits stream creation code into two parts,
public and private stream creation.
Fixes#17009.
This commit replaces 'allow_message_deleting' boolean setting
with an integer setting 'delete_own_message_policy'. We have a
separate dropdown now for deciding which user-roles can delete
messages sent by themselves and the time-limit setting droddown
is different.
This new setting has two options - everyone and admins only. Other
options including moderators will be added further.
We also remove the "Never" option from the original time-limit
dropdown, as admins are always allowed to delete message. This
never option resembled the case of only admins being allowed to
delete but this state is now resembled by setting the dropdown
to "admins only" and we also disable the time-limit dropdown in
this case as admins are allowed to delete irrespective of limit.
Note, this setting is only for deleting messages sent by the
deleting user themselves, and only admins are allowed to delete
messages sent by others as before.
We make zero invalid value for message_content_delete_limit_seconds and
for handling the case of "Allow to delete message any time", the API-level
value of message_content_delete_limit_seconds is "anytime" and "None"
as the DB-level value. We also use these values for message retention
setting, so it helps maintain consistency.
This is a somewhat subtle function, that deserves a few comments
explaining subtle details of its logic, and there's no good reason to
have multiple copies of that logic that are slightly inconsistent.
Because the main changes here are just checking for invariant
failures, the behavioral change here should be limited to ensuring
deactivated streams are not considered available even if they were
tagged as web public streams before deactivation.
This commit removes the existing default_twenty_four_hour_time field in
Realm table which was used to set the twenty_four_hour_time setting of
new user on joining and instead we now use the twenty_four_hour_time
field of RealmUserDefault table for the same.
With some tweaks by tabbott to clarify the documentation.
These values are currently either a string already or a List[int]. We
should do the conversion in
do_update_user_custom_profile_data_if_changed properly: if the value is
already a string, it can be used directly - if it's not, orjson.dumps is
a more future-proof way of converting than str(). Using orjson.dumps
here also allows us to change the converter of the USER type
CustomProfileField to orjson.loads, which is nicer to have than
ast.literal_eval.
While orjson.dumps() and str() give the same output when
given the special case of List[int],
ast.literal_eval was previously used due to orjson.loads not being
a good inverse function to str in general. That gets straightened out
now.
None of the existing custom profile field types have the value as an
integer like declared in many places - nor is it a string like currently
decalred in types.py. The correct type is Union[str, List[int]]. Rather
than tracking this in so many places throughout the codebase, we add a
new ProfileDataElementValue type and insert it where appropriate.
This new setting both serves as a guard to allow us to merge API
support for web public streams to main before we're ready for this
feature to be available on Zulip Cloud, and also long term will
protect self-hosted servers from accidentally enabling web-public
streams (which could be a scary possibility for the administrators of
a corporate Zulip server).
This is a follow-up to #19388.
We will in the future allow patch requests to change the visibility
of an existing topic, so `last_updated` is better name for this field.
This commit does not affect the API or events in any way, but only the
database.
Now, when we add a custom animated emoji to the realm
we also save a still image of it (1st frame of the gif). So
we can avoid showing an animated emoji every time.
This extends the invite api endpoints to handle an extra
argument, expiration duration, which states the number of
days before the invitation link expires.
For prereg users, expiration info is attached to event
object to pass it to invite queue processor in order to
create and send confirmation link.
In case of multiuse invites, confirmation links are
created directly inside do_create_multiuse_invite_link(),
For filtering valid user invites, expiration info stored in
Confirmation object is used, which is accessed by a prereg
user using reverse generic relations.
Fixes#16359.
This commit adds do_set_realm_user_default_setting which
will be used to change the realm-level defaults of settings
for new users.
We also add a new event type "realm_user_settings_defaults"
for these settings and a "realm_user_settings_default" object
in '/register' response containing all the realm-level default
settings.
This was likely initiall created with null=True in
5c5ffd6ea3 just because we didn't have a
plan for backfilling this field, but I verified that Zulip Cloud has
no realms without a name set, and that's the place most likely to have
any form of super-legacy nameless realms.
So we can clean up this aspect of the data model without a special
migration to do something with existing realms with name=None (which I
suspect would have resulted in a 500 anyway).
This fixes a regression where one could end up deactivating all owners
of a realm when trying to synchronize LDAP with the `is_realm_admin`
flag configured in `AUTH_LDAP_USER_FLAGS_BY_GROUP`.
With tweaks by tabbott to add is_moderator as well.
Fixes#18677.
Since 84742a0, all settings are sent in the `user_settings` dictionary
which were previously sent inline with other fields in /register
response.
In order to simplify the process of adding new personal settings, we
want to transition to a world where new settings only need to consider
the `property_types` object, and code that needs to reference the
legacy behavior interacts with an object with `legacy` in its name.
This way, contributors working on new settings don't need to think
about the legacy code paths at all.
See https://chat.zulip.org/#narrow/stream/378-api-design/topic/user.20settings.20response.20in.20.2Fregister
to understand this better.
We move the emojiset_choices method from UserProfile class to
UserBaseSettings class because emojiset_choices exists in
UserBaseSettings class and this would be used for realm-level
settings as well along with existing user-level settings.
The `user_activity_interval` worker calls:
```python3
last = UserActivityInterval.objects.filter(user_profile=user_profile).order_by("-end")[0]
`````
Which results in a query like:
```sql
SELECT "zerver_useractivityinterval"."id", "zerver_useractivityinterval"."user_profile_id", "zerver_useractivityinterval"."start", "zerver_useractivityinterval"."end" FROM "zerver_useractivityinterval" WHERE "zerver_useractivityinterval"."user_profile_id" = 12345 ORDER BY "zerver_useractivityinterval"."end" DESC LIMIT 1
```
For users which have at least one matching row, this results in a
query plan like:
```
Limit (cost=0.56..711.38 rows=1 width=24) (actual time=0.078..0.078 rows=1 loops=1)
-> Index Scan Backward using zerver_useractivityinterval_7f021a14 on zerver_useractivityinterval (cost=0.56..1031399.46 rows=1451 width=24) (actual time=0.077..0.078 rows=1 loops=1)
Filter: (user_profile_id = 12345)
Rows Removed by Filter: 98
Planning Time: 0.059 ms
Execution Time: 0.088 ms
```
But for users that have just been created, with no matching rows, this
is considerably more expensive:
```
Limit (cost=0.56..711.38 rows=1 width=24) (actual time=10798.146..10798.146 rows=0 loops=1)
-> Index Scan Backward using zerver_useractivityinterval_7f021a14 on zerver_useractivityinterval (cost=0.56..1031399.46 rows=1451 width=24) (actual time=10798.145..10798.145 rows=0 loops=1)
Filter: (user_profile_id = 12345)
Rows Removed by Filter: (count of every single row in the table, redacted)
Planning Time: 0.053 ms
Execution Time: 10798.158 ms
```
Regular vacuuming can force the use of the index on `user_profile_id`
as long as there are few enough users, which is fast -- however, at
some point, the query planner decides that is insufficiently specific,
always chooses the effective-whole-table-scan.
Add an index on `(user_profile_id, end)`, which is expected to be
sufficiently specific that it is used even with large numbers of user
profiles.

This commit updates both the stream-level and realm-level message
retention setting to use 'unlimited' instead of 'forever' to set
message retention setting to "retain messages forever".
Previously, we checked for the `enable_offline_email_notifications` and
`enable_offline_push_notifications` settings (which determine whether the
user will receive notifications for PMs and mentions) just before sending
notifications. This has a few problem:
1. We do not have access to all the user settings in the notification
handlers (`handle_missedmessage_emails` and `handle_push_notifications`),
and therefore, we cannot correctly determine whether the notification should
be sent. Checks like the following which existed previously, will, for
example, incorrectly not send notifications even when stream email
notifications are enabled-
```
if not receives_offline_email_notifications(user_profile):
return
```
With this commit, we simply do not enqueue notifications if the "offline"
settings are disabled, which fixes that bug.
Additionally, this also fixes a bug with the "online push notifications"
feature, which was, if someone were to:
* turn off notifications for PMs and mentions (`enable_offline_push_notifications`)
* turn on stream push notifications (`enable_stream_push_notifications`)
* turn on "online push" (`enable_online_push_notifications`)
then, they would still receive notifications for PMs when online.
This isn't how the "online push enabled" feature is supposed to work;
it should only act as a wrapper around the other notification settings.
The buggy code was this in `handle_push_notifications`:
```
if not (
receives_offline_push_notifications(user_profile)
or receives_online_push_notifications(user_profile)
):
return
// send notifications
```
This commit removes that code, and extends our `notification_data.py` logic
to cover this case, along with tests.
2. The name for these settings is slightly misleading. They essentially
talk about "what to send notifications for" (PMs and mentions), and not
"when to send notifications" (offline). This commit improves this condition
by restricting the use of this term only to the database field, and using
clearer names everywhere else. This distinction will be important to have
non-confusing code when we implement multiple options for notifications
in the future as dropdown (never/when offline/when offline or online, etc).
3. We should ideally re-check all notification settings just before the
notifications are sent. This is especially important for email notifications,
which may be sent after a long time after the message was sent. We will
in the future add code to thoroughly re-check settings before sending
notifications in a clean manner, but temporarily not re-checking isn't
a terrible scenario either.

We still keep refering to this model with "MutedTopic" to reduce the
diff size of this commit. The alias will be removed in the next commit.
This commit skips on renaming the `date_muted` field to something more
general. That will be done in further commits, along with the code and
API changes.
This commit adds can_add_custom_emoji
helper to check whether the user can
add custom emoji or not.
This function will be used further when
add_custom_emoji_policy will be extended
to include all COMMON_POLICY_VALUES.
This commit replaces boolean field add_emoji_by_admins_only with an
integer field add_custom_emoji_policy as we would also add full members
and moderators option for this setting in further commits.
This commit moves "enter_sends" setting to property_types dict.
With this change, changing enter_sends setting also sends an
event of type "update_display_settings" and thus enables us
to live-update the UI.
This field will control whether or not a user wants to sync their
drafts between different clients. Defaults to enabled.

This makes several changes:
* Fixes a bug where the help text explaining our policies was not displayed.
* No help text was defined for many organization types.
* Copy-edits the help text somewhat.
* Offers all of the organization type options.
* Removes the 100% coverage requirement because it's annoying to test
the e.currentTarget click handler.
We are starting to run into situations where this data could be
quite useful for making future decisions, so it makes to store it
in the database, not just in an email.
Moving forward we are hoping to collect data on org types from our
users, so it makes sense to display the org type on the "Counts"
tab of our /activity page.
This commit adds moderators and full members options for
user_group_edit_policy by using COMMON_POLICY_TYPES.
Moderators do not require to be a member of user group in
order to edit or remove the user group if they are allowed
to do so according to user_group_edit_policy.
But full members need to be a member of user group to edit
or remove the user group.
This will be used to store the missedmessage events received
during the waiting time for email notifications (which is currently
2 minutes, hardcoded).
The change in `test_retention` is because we've set `on_delete=CASCADE`
for the message field this table.
The new query is like so:
```
DELETE FROM "zerver_missedmessageemailentry"
WHERE "zerver_missedmessageemailentry"."message_id" IN (
1545, 1546, 1547, 1548, 1549, 1550, 1551, 1552, 1553
)
```
This reduces loose strings in the codebase, and allows us to not worry
about the exact naming (`stream_email_enabled` or `stream_emails_enabled`?)
and tense (`mentioned` or `mention`?).
Ideally this new class should have been in `lib/notification_data.py`,
which is our file for things like this. But, the next commit requires
using this data in `models.py`, and importing from `notification_data.py`
to `models.py` causes recursive imports.
We add a new class UserBaseSettings and will be moving some of
the user settings to this class from UserProfile and UserProfile
will inherit it.
This is a prep commit for adding RealmUserDefault table which will
be used to set the realm-wide default for user settings like night
mode, etc. Adding UserBaseSettings will help us in avoiding copy
the same fields in RealmUserDefault.
We remove timezone setting from UserProfile.property_types
so that we can directly use UserProfile.property_types for
implementation of realm-default values of various user
settings.
This helper will be used to check whether
the user is allowed to edit user groups or
not. Currently it is not used, but will
be used in next commit where we will
refactor the user_group_edit_policy to use
COMMON_POLICY_TYPES.
This is a follow-up for 98f8d94b25.
For cases when url_format_string is like https://example.com/%%(foo)s/%(bar)s
group_match_regex should only detect `bar` as the intended
parameter and not `foo`.
We now validate the linkifier urls and patterns together, and add
the following additional checks:
1. All groups in the pattern must be used in the URL format string.
2. All groups in the URL format string must be declared in the pattern.
Linkifier pattern is now validated inside the `clean` method.
`filter_pattern_validator` is moved from `clean_fields` to `clean`
method as a safe check. As a result of this, a Puppeteer test case
is updated.
NOTE: The changes here are IN ADDITION to the existing validations.
Fixes#16482.

This commit replaces the allow_community_topic_editing boolean with
integer field edit_topic_policy and includes both frontend and
backend changes.
We also update settings_ui.disable_sub_settings_onchange to not
change the color of label as we did previously when the setting
was a checkbox. But now as the setting is dropdown we keep the
label as it is and we don't do anything with label when disabling
dropdowns. Also, this function was used only here so we can safely
change this.
This will offer users who are self-hosting to adjust
this value. Moreover, this will help to reduce the
overall time taken to test `test_markdown.py` (since
this can be now overridden with `override_settings`
Django decorator).
This is done as a prep commit for #18641.
In the source realm selector, when we select a realm from which we want
to import the data, we pass the source realm's string_id. The problem
with this approach is that the string_id can be an empty string. This
commit makes the source_realm pass the realm's id instead of string_id.
Now, the source_realm's value will either be an integer or "" (empty
string) when we don't want to import settings from any realm.
The comment mentioned the values in this dict to be consistent
wth values in settings_config.invited_as_values.
But settings_config.invited_as_values was replaced by
settings_config.user_role_values in 136c005f3f, so
updated the comment accordingly.
This commit adds both frontend and backend code to invite a user as
moderator. We allow only existing owners and admins to invite a user
as a moderator.
model__id syntax implies needing a JOIN on the model table to fetch the
id. That's usually redundant, because the first table in the query
simply has a 'model_id' column, so the id can be fetched directly.
Django is actually smart enough to not do those redundant joins, but we
should still avoid this misguided syntax.
The exceptions are ManytoMany fields and queries doing a backward
relationship lookup. If "streams" is a many-to-many relationship, then
streams_id is invalid - streams__id syntax is needed. If "y" is a
foreign fields from X to Y:
class X:
y = models.ForeignKey(Y)
then object x of class X has the field x.y_id, but y of class Y doesn't
have y.x_id. Thus Y queries need to be done like
Y.objects.filter(x__id__in=some_list)
This commit adds new helper can_move_messages_between_streams

Organization admins can use this setting to restrict the maximum

This commit removes can_access_all_realm_members function as
it is not used anywhere in code other than tests.
This function was originally added in 4483e33102 and was
only used in digest.py other than the tests, but its use
in diget.py was removed in 735b6cb761 and the function
itself was not removed from models.py.
This logic likely never ran due to a combination of bugs.
* Running `maybe_update_markdown_engines` unconditionally meant that
`if md_engine_key in md_engines` was likely always true.
* Introduced in 65838bb: DEFAULT_MARKDOWN_KEY could never be in
md_engines, so should we have ever reached that code path, we'd have
tried to rebuild all markdown engines every time.
And it also wasn't clearly helpful -- because we fetch all linkifiers
for a realm on every request anyway, we don't really save database
queries by doing a bulk fetch on startup, and doing so would likely
result in a material regression to Zulip's overall startup time that
we were creating markdown engines for large numbers of realms in bulk
during process startup.
This commit defines a new function `get_muting_users`
which will return a list of IDs of users who have muted
a given user.
Whenever someone mutes/unmutes a user, the cache will be
flushed, and subsequently when that user sends a message,
the cache will be populated with the list of people who
have muted them (maybe empty).
This data is a good candidate for caching because-
1. The function will later be called from the message send
codepath, and we try to minimize database queries there.
2. The entries will be pretty tiny.
3. The entries won't churn too much. An average user will
send messages much more frequently than get muted/unmuted,
and the first time penalty of hitting the db and populating
the cache should ideally get amortized by avoiding several
DB lookups on subsequent message sends.
The actual code to call this function will be written in
further commits.
This makes it so that RealmAuditLog entries are
created when a user mutes/unmutes someone.
We don't really need to store the time, but we
do so anyways, because the `event_time` field
is currently a non-nullable one in the `RealmAuditLog`
model, and making it nullable would risk allowing
not specifying the time in other more important
code which also creates `RealmAuditLog` entries.
This also fixes an incorrect test of successfully
unmuting with the API. Earlier it did not mock
the time in the `views/muting.py` code to return
`mute_time`.
* Don't require strings to be unnecessarily JSON-encoded.
* Use check_capped_string rather than custom code for length checks.
* Update frontend to pass the right parameters.
With a much simplified populate_data_for_request design suggested by
Anders; we only support a handful of data types, all of which are
correctly encoded automatically by jQuery.
Fixes part of #18035.
We add moderators and full members option to invite_to_realm_policy
by using COMMON_POLICY_TYPES and use can_invite_others_to_realm helper
added in previous commit. This commit only does the backend work,
frontend work will be done in separate commit.
This commit adds can_invite_others_to_realm helper which will be used in
further in next commit when invite_to_realm_policy will be modified to
support all values of COMMON_POLICY_TYPES.
It is important for this commit's correctness that
INVITE_TO_REALM_POLICY_TYPES was initialized to use the same values.
This commit replaces invite_by_admins_policy, which was a bool field,
with a new enum field invite_by_realm_policy.
Though the final goal is to add moderators and full members option
using COMMON_POLICY_TYPES, but this will be done in a separate
commit to make this easy for review.
We send the whole data set as a part of the event rather than
doing an add/remove operation for couple of reasons:
* This would make the client logic simpler.
* The playground data is small enough for us to not worry
about performance.
Tweaked both `fetch_initial_state_data` and `apply_events` to
handle the new playground event.
Tests added to validate the event matches the expected schema.
Documented realm_playgrounds sections inside /events and
/register to support our openapi validation system in test_events.
Tweaked other tests like test_event_system.py and test_home.py
to account for the new event being generated.
Lastly, documented the changes to the API endpoints in
api/changelog.md and bumped API_FEATURE_LEVEL.
Tweaked by tabbott to add an `id` field in RealmPlayground objects
sent to clients, which is essential to sending the API request to
remove one.
Tweaked exports.py to add the config object there so that our export
tool can include the table when exporting. Also includes all the
changes required to import the new table from the exported data.
Helper function `get_realm_playgrounds` added to fetch all
playgrounds in a realm.
Tests amended.
Adds backend code for the mute users feature.
This is just infrastructure work (database
interactions, helpers, tests, events, API docs
etc) and does not involve any behavioral/semantic
aspects of muted users.
Adds POST and DELETE endpoints, to keep the
URL scheme mostly consistent in terms of `users/me`.
TODOs:
1. Add tests for exporting `zulip_muteduser` database table.
2. Add dedicated methods to python-zulip-api to be used
in place of the current `client.call_endpoint` implementation.
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.
This adds the is_user_active with the appropriate code for setting the

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.
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.
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.
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.
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.
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.

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.
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 export a realm's data, and disable the realm, because the user
is moving from Zulip Cloud (e.g. https://example.zulipchat.com/) to
self-hosting or another platform (e.g. https://zulip.example.com/)
which we do not control. This commit adds a field in the realm object
called deactivated_redirect to store the url to which the realm has
moved.
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.
Then because the ID is now part of the draft dict, we can
(and do) change the structure of the "drafts" parameter
returned from `GET /drafts` from an object (mapping ID to

We add a new wildcard_mention_policy setting to handle wildcard
mentions in large streams, with a wide range of policies available to
organizations.
We set the default to the safe option for preventing accidental spam:
only stream administrators being able to use wildcard mentions in
large streams.
There are three functional side effects:
• Correct an insignificant but mathematically offensive bias toward
repeated characters in generate_api_key introduced in commit
47b4283c4b4c70ecde4d3c8de871c90ee2506d87; its entropy is increased
from 190.52864 bits to 190.53428 bits.
• Use the base32 alphabet in confirmation.models.generate_key; its
entropy is reduced from 124.07820 bits to the documented 120 bits, but
now it uses 1 syscall instead of 24.
• Use the base32 alphabet in get_bigbluebutton_url; its entropy is
reduced from 51.69925 bits to 50 bits, but now it uses 1 syscall
instead of 10.
(The base32 alphabet is A-Z 2-7. We could probably replace all of
these with plain secrets.token_urlsafe, since I expect most callers
can handle the full urlsafe_b64 alphabet A-Z a-z 0-9 - _ without
problems.)

This commit adds "role" field to the Subscription objects passed to
clients. This is important preparation for being able to work on the
frontend for this feature.
This commit adds the is_web_public field in the AbstractAttachment
class. This is useful when validating user access to the attachment,
as otherwise we would have to make a query in the db to check if
that attachment was sent in a message in a web-public stream or not.
This commit adds role field to the Subscription class. Currently,
there are two option of roles - STREAM_ADMINISTRATOR and MEMBER.
We also add a property 'is_stream_admin' for checking whether the
user is stream admin or not.
Also add a Draft object-to-dictionary conversion method.
The following commits will provide an API around this

Fixes#15410
A few major themes here:
- We remove short_name from UserProfile
and add the appropriate migration.
- We remove short_name from various
cache-related lists of fields.
- We allow import tools to continue to
write short_name to their export files,
and then we simply ignore the field
at import time.
- We change functions like do_create_user,
create_user_profile, etc.
- We keep short_name in the /json/bots
API. (It actually gets turned into
an email.)
- We don't modify our LDAP code much
here.
Log RealmAuditLog in do_set_realm_property and do_remove_realm_domain.
Tests for the changes are written in test_events because it will save
duplicate code for test_change_realm_property.
Added new Event Type in AbstractRealmAuditLog STREAM_CREATED.
Since we finally create streams in create_stream_if_needed function
in zerver/lib/streams.py so logged realm_audit there.
Passed acting_user when create_stream_if_needed or ensure_stream
function is called.
Added tests in test_audit_log.
This was hiding an actual type error in test_cache: a mismatch between
the object ID type, which is str, and the default id_fetcher, which
returns int.
Mypy’s insufficient support for default generic arguments basically
means we can’t use them without a lot of overloading, and there are
not enough callers here to justify that.

This eval function performs the inverse of the implicit

This commit changes the PreregistrationUser.invite_as dict to have
same set of values as we have for UserProfile.role.
This also adds a data migration to update the already exisiting
PreregistrationUser and MultiuseInvite objects.
Currently, we use -1 as the Realm.message_retention_days value to retain
message forever unless specified at stream level for a particular stream,
that is, no policy set at the realm level. But this is incoherent with what
we use for Stream.message_retention_days where -1 means
> disable retention policy for this stream unconditionally
that can be confusing from an API standpoint.
So instead of trying some hack to reset the value to NULL or using some
other value like -2 for RETAIN_MESSAGE_FOREVER and use that for API. It is
much more intuitive to use a string like 'forever' that can be mapped to
RETAIN_MESSAGE_FOREVER at the backend. And this is similar to what we use
for streams settings as well.
To be more consistent with the meaning in the Stream model, and to make
it easier to have a reasonable settings API, we get rid of the None
value for Realm.message_retention_days in favor of the value -1 to
represent the "don't delete messages" default policy.
With this implementation of the feature of the automatic theme
detection, we make the following changes in the backend, frontend and
documentation.
This replaces the previous night_mode boolean with an enum, with the
default value being to use the prefers-color-scheme feature of the
operating system to determine which theme to use.

Attachment objects in production are only created in one place, which
passses a size. Additionally, I verified in multiple production
environments with old data that this never actually happens (or has
happened).
So we should make the data model correctly reflect the possibilities here.
This fixes a missing unique constraint on the Reactions data model
state when using multiple aliases for an emoji code. As with any
missing unique constraints, we first need to apply a migration that
eliminates violations of the rule; in this case, deleting the
duplicates is correct.
Added unique constraint for "user_profile", "message",
"reaction_type", "emoji_code".
Fixes#15347.
This commit adds backend support for setting message_retention_days
while creating streams and updating it for an existing stream. We only
allow organization owners to set/update it for a stream.
'message_retention_days' field for a stream existed previously also, but
there was no way to set it while creating streams or update it for an
exisiting streams using any endpoint.
The most import change here is the one in maybe_send_to_registration
codepath, as the insufficient validation there could lead to fetching
an expired PreregistrationUser that was invited as an administrator
admin even years ago, leading to this registration ending up in the
new user being a realm administrator.
Combined with the buggy migration in
0198_preregistrationuser_invited_as.py, this led to users incorrectly
joining as organizations administrators by accident. But even without
that bug, this issue could have allowed a user who was invited as an
administrator but then had that invitation expire and then joined via
social authentication incorrectly join as an organization administrator.
The second change is in ConfirmationEmailWorker, where this wasn't a
security problem, but if the server was stopped for long enough, with
some invites to send out email for in the queue, then after starting it
up again, the queue worker would send out emails for invites that
had already expired.

This commit adds three `.pysa` model files: `false_positives.pysa`
for ruling out false positive flows with `Sanitize` annotations,
`req_lib.pysa` for educating pysa about Zulip's `REQ()` pattern for

of open redirects within Zulip code. Additionally, this commit
introduces `mark_sanitized`, an identity function which can be used
to selectively clear taint in cases where `Sanitize` models will not
work. This commit also puts `mark_sanitized` to work removing known
false postive flows.
This commit adds some basic checks while adding or removing
realm owner status of a user and adds code to change owner
status of a user using update_user_backend.
This also adds restriction on removing owner status of the

role of realm owner, we now have this restriction on owner
instead of admin.
We need to apply that restriction both in the role change code path
and the deactivate code path.

This commit modifies the backend to accept user ids when subscribing
users to streams.
It also migrates all existing tests to use this API, aside from a
small set of tests for the legacy API.
There's no reason to send data beyond the user `id` of the uploader,
and reason not to, as the previous model was both awkward when
`author=None` and resulted in unecessary parsing complexity for

Since production testing of `message_retention_days` is finished, we can
enable this feature in the organization settings page. We already had this
setting in frontend but it was bit rotten and not rendered in templates.
Here we replaced our past text-input based setting with a
dropdown-with-text-input setting approach which is more consistent with our
existing UI.
Along with frontend changes, we also incorporated a backend change to
handle making retention period forever. This change introduces a new
convertor `to_positive_or_allowed_int` which only allows positive integers
and an allowed value for settings like `message_retention_days` which can
be a positive integer or has the value `Realm.RETAIN_MESSAGE_FOREVER` when
we change the setting to retain message forever.
This change made `to_not_negative_int_or_none` redundant so removed it as
well.

Closes#14798.
This reverts commit 8f32db81a1.
This change unfortunately requires an index that we don't have, and
thus is incredibly expensive. We'll need to do a thoughtful reworking
before we can integrate it again.
The post_init cache-flushing behavior in the original alert words
migration was subtly wrong; while it may have passed tests, it didn't
have the right ordering for unlikely races.
We use post_save rather than post_init hooks precisely because they
ensure that we flush the cache after we know the database has been
updated and any future reads from the database will have the latest
state.
Previously, alert words were case-insensitive in practice, by which I
mean the Markdown logic had always been case-insensitive; but the data
model was not, so you could create "duplicate" alert words with the
same words in different cases. We fix this inconsistency by making
the database model case-insensitive.
I'd prefer to be using the Postgres `citext` extension to have
postgres take care of case-insensitive logic for us, but that requires
installing a postgres extension as root on the postgres server, which
is a pain and perhaps not worth the effort to arrange given that we
can achieve our goals with transaction when adding alert words.
We take advantage of the migrate_alert_words migration we're already
doing for all users to effect this transition.
Fixes#12563.
Previously, alert words were a JSON list of strings stored in a
TextField on user_profile. That hacky model reflected the fact that
they were an early prototype feature.
This commit migrates from that to a separate table, 'AlertWord'. The
new AlertWord has user_profile, word, id and realm(denormalization so
we can provide a nice index for fetching all the alert words in a
realm).
This transition requires moving the logic for flushing the Alert Words
caches to their own independent feature.
Note that this commit should not be cherry-picked without the
following commit, which fixes case-sensitivity issues with Alert Words.
When a user is reading messages only in stream or topic narrows, the pointer
can be left far behind. Using this to compute the furthest_read_time causes
the banckruptcy banner to be shown even when a user has been actively
reading messages. This commit switches to using the sent time on the last
message that the user has read to compute the furthest read time.
In Django 2.1, the preferred way to express a nullable BooleanField

This extends our email address visibility settings to deny access to
user email addresses even to organization administrators.
At the moment, they can of course change the setting (which leaves an
audit trail), but in the future only organization owners will be able

the cases in a more consistent way.
Fixes#14111.
We will cache failed lookups with None. The
use case here is that broken API clients may
continually ask for the same wrong API key, and
we want to handle that as quickly as possible.
The main purpose of this new function is to allow
us to validate emails in bulk, which we don't do
yet (still setting the stage for that).
This is still a speedup, though, since in our
caller we grab only three fields now.
And other than that, we're essentially doing
the same query for the single-email case, just
outside the loop.
We now query RealmDomain objects up front. This
change is minor in most circumstances--it sometimes
saves a round trip to the database; other times,
it actually brings back slightly more data
(optimistically).
The big win will come in a subsequent commit,
where we avoid running these queries in a loop
for every callback.
Note that I'm not sure if we intentionally
omitted checks for emails with "+" in them
for some circumstances, but I just preserved
the behavior.
This function slims down the data that we get
from the database in order to create the
streams part of our client payload.
We also fix a typo.
We also clearly distinguish between queries
and lists here.

fetching presence data for the whole realm from the database on
servers like zulipchat.com hosting several realms.
This index is intended to optimize the performance of the very
frequently run query of "what is the presence status of all users in a
realm?".
Main changes:
- add realm_id to UserPresence
- add index for realm_id
- backfill realm_id for old rows
- change all writes to UserPresence to include
realm_id
The index is of this form:
"zerver_userpresence_realm_id_5c4ef5a9" btree (realm_id)
We will create an index on (realm_id, timestamp) in a
future commit, but I think it's a bit faster if you do
the backfill before the index.
There's also a minor tweak to the populate_db script.
This commit includes a new `stream_post_policy` setting,
by replacing the `is_announcement_only` field from the Stream model,
which is done by mirroring the structure of the existing
`create_stream_policy`.
It includes the necessary schema and database migrations to migrate
the is_announcement_only boolean field to stream_post_policy,
a smallPositiveInteger field similar to many other settings.
This change is done to allow organization administrators to restrict
new members from creating and posting to a stream. However, this does
not affect admins who are new members.
With many tweaks by tabbott to documentation under /help, etc.
Fixes#13616.
