This commit changes web_public_streams_enabled to return False if
realm.enable_spectator_access is False. This is added so that
creating web-public streams is not allowed if enable_spectator_access
is False.
We restrict access of messages from web public streams if
anonymous login is disabled via `enable_spectator_access`.
Display of `Anonymous login` button is now controlled by
the value of `enable_spectator_access`.
Admins can toggle `enable_spectator_access` via org settings in UI.
Previously, our codebase contained links to various versions of the
Django docs, eg https://docs.djangoproject.com/en/1.8/ref/
request-response/#django.http.HttpRequest and https://
docs.djangoproject.com/en/2.2/ref/settings/#std:setting-SERVER_EMAIL
opening a link to a doc with an outdated Django version would show a
warning "This document is for an insecure version of Django that is no
longer supported. Please upgrade to a newer release!".
Most of these links are inside comments.
Following the replacement of these links in our docs, this commit uses
a search with the regex "docs.djangoproject.com/en/([0-9].[0-9]*)/"
and replaces all matches with "docs.djangoproject.com/en/3.2/".
All the new links in this commit have been generated by the above
replace and each link has then been manually checked to ensure that
(1) the page still exists and has not been moved to a new location
(and it has been found that no page has been moved like this), (2)
that the anchor that we're linking to has not been changed (and it has
been found that no anchor has been changed like this).
One comment where we mentioned a Django version in text before linking
to a page for that version has also been changed, the comment
mentioned the specific version when a change happened, and the history
is no longer relevant to us.
Add `escape_navigates_to_default_view` as a bool setting in
UserBaseSettings model and implement it as a checkbox that toggles
the hotkey implementation of escape to the default view in the
advanced user display settings.
With /help/ documentation edits from Alya Abbott.
Fixes#20043.
Supporting URL percent-encoded bytes is possible using `%%20`, but this
is not necessarily very understandable to end-users, even those that
understand percent encoding.
Allow `%20` in linkifier URL format strings, and transform them into
`%%20` in the pattern just before they are applied in markdown
translation. Care must be taken here, such that already-escaped `%`s
are not escaped an extra time.
We do this before rendering, and not before storage, as
a simplification; the JS-side linkifier at present only understands
`%(foo)s` and thus needs no changes, and to avoid an un-escaping pass
before showing in the admin UI.
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.

These changes are all independent of each other; I just didn’t feel
like making dozens of commits for them.

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.
Part of #19272
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.
