1. The initial welcome message now contains less detail.
2. The bot now responds to these commands: "apps", "edit profile",
"dark mode", "light mode", "streams", "topics", "message formatting",
"keyboard shortcuts" and "help" - the bot still responds if there are
slight variations in these commands.
3. Tests have been made to check if bot responds to the advertised
commands (with variations) and gives a negative message if it doesn't
understand the message.
With substantial tweaks by tabbott.
Fixes#19900.
A confirmation link takes a user to the check_prereg_key_and_redirect
endpoint, before getting redirected to POST to /accounts/register/. The
problem was that validation was happening in the check_prereg_key_and_redirect
part and not in /accounts/register/ - meaning that one could submit an
expired confirmation key and be able to register.
We fix this by moving validation into /accouts/register/.
Migrates the `/update-subscription-settings` api endpoint to the
`ignored_parameters_unsupported` model, which is also currently used
by `/update-settings` and `update-realm-user-settings-defaults`.
This change is a step towards preparing for an eventual migration to
have all endpoints return an `ignored_parameters_unsupported` block.
Previously the `/update-subscription-settings` endpoint returned a
copy of the data object sent in the request.
Fixes#15307.
django-scim2 doesn't order the rows when fetching them in reponse to a
query using the filter syntax. We ensure that ORDER BY id is always
appended to the SQL queries.
We add the following tables to the user export:
AlertWord
CustomProfileFieldValue
RealmAuditLog
Service
UserActivity
UserActivityInterval
UserCount
UserGroup
UserHotspot
UserPresence
UserTopic
Except for UserCount, we achieve this by sharing
code with the realm export via
add_user_profile_child_configs.
UserCount is handled slightly differently than realm
exports due to which key we trigger off.
It's possible that RealmAuditLog is incomplete for
single users, since we may also want rows where they
are the acting_user. This commit finds rows where
they are the modified_user. For non-admins I believe
it's rarely the case that they are the actor, and
they will tend to be the modified user if the two
fields are different at all. For admins it's
arguable we want to see both changes they enacted
as well as changes that affected them.
This commit switches the BigBlueButton integration
to use SHA256 instead of SHA1 as BigBlueButton supports
it and scalelite does now, too.
Fixes#19966.
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.
Python's behaviour on `sys.exit` is to wait for all non-daemon threads
to exit. In the context of the missedmessage_emails worker, if any
work is pending, a non-daemon Timer thread exists, which is waiting
for 5 seconds. As soon as that thread is serviced, it sets up another
5-second Timer, a process which repeats until all
ScheduledMessageNotificationEmail records have been handled. This
likely takes two minutes, but may theoretically take up to a week
until the thread exits, and thus sys.exit can complete.
Supervisor only gives the process 30 seconds to shut down, so
something else must prevent this endless Timer.
When `stop` is called, take the lock so we can mutate the timer.
However, since `stop` may have been called from a signal handler, our
thread may _already_ have the lock. As Python provides no way to know
if our thread is the one which has the lock, make the lock a
re-entrant one, allowing us to always try to take it.
With the lock in hand, cancel any outstanding timers. A race exists
where the timer may not be able to be canceled because it has
finished, maybe_send_batched_emails has been called, and is itself
blocked on the lock. Handle this case by timing out the thread join
in `stop()`, and signal the running thread to exit by unsetting the
timer event, which will be detected once it claims the lock.
Special characters, including `\r`, `\n`, and more esoteric codepoints
like non-characters, can negatively affect rendering and UI behaviour.
Check for, and prevent making new messages with, characters in the
Unicode categories of `Cc` (control characters), `Cs`, (surrogates),
and `Cn` (unassigned, non-characters).
Fixes#20128.
This commit replaces "dark mode" and "light mode" with "dark theme"
and "light theme" in the message returned and shown in a little
popup in the UI, when color scheme settings are changed through
slash commands.
Adds `wildcard_mentions_notify` as a property that can be updated
by the endpoint and removes mention of potential `null` value in
the return object because it is not possible.
Also cleans up the documentation of `in_home_view` legacy property
and updates the return object description to better reflect what
is actually returned.
Since spectators can't access personal profile settings and
can't view profile for other users. Hence, we don't send realm
custom profile field data and user's profile data to spectators.
Fixes#20301.
Enable spectator access for test `zulip` realm in developement
setup.
Add option in `do_create_realm` to configure
`enable_spectator_access` field of `Realm`.
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.
If null is a potential value of data type for a return value or
parameter in the API endpoint, then it is rendered as an option.
This currently relies on the 'nullable' setting in the OpenAPI spec
that was removed in the 3.1.0 release. If/when the OpenAPI version
is updated, then how the `data_type` for parameters and return values
is rendered will need to be reworked.
Fixes#20264.
It turns out these were just wrong. We fix a few things:
* Sort the list of settings so that it's possible to compare with reality.
* Deleted additional fields that don't actually exist.
* Fixed various fields missing past feature level updates.
Neither of these fields use the `realm/update_dict` event type; they
use `realm/update`; we've attempted to clarify that in the previous
commit.
That reality means we don't have automated testing for these values,
and that meant that typos like these could slip through.
The user id is a very useful piece of information that the mobile
client should have access to - instead of only getting the email. This
makes it much simpler to impleent clients that might be robust to
changes in email address.
RabbitMQ clients have a setting called prefetch[1], which controls how
many un-acknowledged events the server forwards to the local queue in
the client. The default is 0; this means that when clients first
connect, the server must send them every message in the queue.
This itself may cause unbounded memory usage in the client, but also
has other detrimental effects. While the client is attempting to
process the head of the queue, it may be unable to read from the TCP
socket at the rate that the server is sending to it -- filling the TCP
buffers, and causing the server's writes to block. If the server
blocks for more than 30 seconds, it times out the send, and closes the
connection with:
```
closing AMQP connection <0.30902.126> (127.0.0.1:53870 -> 127.0.0.1:5672):
{writer,send_failed,{error,timeout}}
```
This is https://github.com/pika/pika/issues/753#issuecomment-318119222.
Set a prefetch limit of 100 messages, or the batch size, to better
handle queues which start with large numbers of outstanding events.
Setting prefetch=1 causes significant performance degradation in the
no-op queue worker, to 30% of the prefetch=0 performance. Setting
prefetch=100 achieves 90% of the prefetch=0 performance, and higher
values offer only minor gains above that. For batch workers, their
performance is not notably degraded by prefetch equal to their batch
size, and they cannot function on smaller prefetches than their batch
size.
We also set a 100-count prefetch on Tornado workers, as they are
potentially susceptible to the same effect.
[1] https://www.rabbitmq.com/confirms.html#channel-qos-prefetch
The `current_queue_size` key in the queue monitoring stats file was
the local queue size, not the global queue size -- d5a6b0f99a
renamed the function, but did not adjust the queue monitoring JSON,
despite the last use of it having been removed in cd9b194d88.
The function is still used to mark "we emptied our queue," and it
remains a reasonable metric for that.
TOR users are legitimate users of the system; however, that system can
also be used for abuse -- specifically, by evading IP-based
rate-limiting.
For the purposes of IP-based rate-limiting, add a
RATE_LIMIT_TOR_TOGETHER flag, defaulting to false, which lumps all
requests from TOR exit nodes into the same bucket. This may allow a
TOR user to deny other TOR users access to the find-my-account and
new-realm endpoints, but this is a low cost for cutting off a
significant potential abuse vector.
If enabled, the list of TOR exit nodes is fetched from their public
endpoint once per hour, via a cron job, and cached on disk. Django
processes load this data from disk, and cache it in memcached.
Requests are spared from the burden of checking disk on failure via a
circuitbreaker, which trips of there are two failures in a row, and
only begins trying again after 10 minutes.
Unhandled exceptions propagating to process_queue were not caught there,
causing improper logging - errors didn't land in errors.log as expected.
Exceptions should be caught and explicitly logged by the process_queue
logger. Exceptions occurring during consuming events are caught and
handled inside the worker's logic - however those that happen while
setting up the worker were not addressed at all, and that's the core bug
we mean to address here.
Furthermore, in multi-threaded mode we want the autoreload mechanism to
be working - which it doesn't without catching the exceptions. The
correct approach is to - again - catch the exception, log it and then
send SIGUSR1 signal to trigger exit and autoreload.
I believe that this migration with the default of atomic=True will
fail when trying to convert the field to PositiveIntegerField if there
were any 0 values present in the database when the migration began.
The fix is to have each of the steps be their own transaction.
A SIGTERM can show up at any point in the ioloop, even in places which
are not prepared to handle it. This results in the process ignoring
the `sys.exit` which the SIGTERM handler calls, with an uncaught
SystemExit exception:

Supervisor then terminates the process with a SIGKILL, which results
in dropping data held in the tornado process, as it does not dump its
queue.
The only command which is safe to run in the signal handler is
`ioloop.add_callback_from_signal`, which schedules the callback to run
during the course of the normal ioloop. This callbacks does an
orderly shutdown of the server and the ioloop before exiting.
This commit ensures that all markdown fixtures have unique
test names by rewriting the names of some of them and adding
a test in `test_markdown.py`.
Earlier this was over-writing the value for same keys in
`load_markdown_tests` in `test_markdown.py`.
Race conditions in stream unsubscription may lead to multiple
back-to-back SUBSCRIPTION_DEACTIVATED RealmAuditLog entries for the
same stream. The current logic constructs duplicate UserMessage
entries for such, which then later fail to insert.
Keep a set of message-ids that have been prep'd to be inserted, so
that we don't duplicate them if there is a duplicated
SUBSCRIPTION_DEACTIVATED row. This also renames the `message` local
variable, which otherwise overrode the `message` argument of a
different type.
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.
This resolves the issues reported in #20108, major chunk of which were
due to the incomplete support for importing the livechat streams/messages
in the tool. So, it's best not to import any livechat streams/messages for
now until a complete support for importing the same is developed.
The decorator form is clearer by being more explicit; additionally,
the api_by_user rate-limit only currently used in one place, and makes
it difficult to test per-user rate-limits that are more specific.
Both `create_realm_by_ip` and `find_account_by_ip` send emails to
arbitrary email addresses, and as such can be used to spam users.
Lump their IP rate limits into the same bucket; most legitimate users
will likely not be using both of these endpoints at similar times.
The rate is set at 5 in 30 minutes, the more quickly-restrictive of
the two previous rates.
The existing test did no verify that the rate limit only applied to
127.0.0.1, and that other IPs were unaffected. For safety, add an
explicit test of this.
The only use case of rate_limit_rule which does not clear the
RateLimitedIPAddr history is test_hit_ratelimits_as_remote_server,
which is not made any worse by clearing out the IP history for a
non-existent `api_by_remote_server` domain.
Since `prefers_web_public_view` key in session is only
relevant to users without an account, this key should no longer
be present in the user's session object.
Fixes#19907
For export realm following changes have been made:
- `./manage.py export --upload` would delete `.tar.gz` and unpacked dir
- `./manage.py export` would only delete `unpacked dir`
Besides, we have removed `--delete-after-upload` as we have set it as
the default.
Fixes#20081
If realm is web_public, spectators can now view avatar of other
users.
There is a special exception we had to introduce in rest model to
allow `/avatar` type of urls for `anonymous` access, because they
don't have the /api/v1 prefix.
Fixes#19838.
This commit adds functionality to import messages from the
Discussions having direct channels as their parent. As we don't
have topics in the PMs, the messages are imported in interleaved
form in the imported direct channels/PMs.
This was completely unsupported earlier and would have resulted in
an error.
This commit updates the error message returned when the maximum
invite limit for the day. We update the error returned by API to
only mention that the limit is reached and add the suggestion
to use multi-use link or contact support in the message shown
in webapp.
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.
We always use delivery_email to generate gravatar_url, but in
test_admin_api_hide_emails we were passing email to get_gravatar_url
and matched with the avatar_url field of the fetched user object.
The tests were passing because the email_address_is_realm_public
was using old realm object and thus email field was incorrectly
set to delivery_email even when email_address_visibility was set
to EMAIL_ADDRESS_VISIBILITY_ADMINS.
This commit fixes the test to pass delivery_email to get_gravatar_url.
We create RealmUserDefault object for internal realm just
for consistency. The code in migration does so but it
was missed to add the code when creating new internal realm.
Not proxying these requests through camo is a security concern.
Furthermore, on the desktop client, any embed image which is hosted on
a server with an expired or otherwise invalid certificate will trigger
a blocking modal window with no clear source and a confusing error
message; see zulip/zulip-desktop#1119.
Rewrite all `message_embed_image` URLs through camo, if it is enabled.
We add discussion id and url in the comments and highlighted title to
the body of disscussion message to make it more meaningful and accessible.
Fixes#19938.
We aim to use Zulip topics thoughtfully in displaying messages from
discussions, as well as linking to the discussion in every message so
that it's easy to view them.
Fixes#19938.
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.
og:image is supposed to be an absolute URL, but some sites incorrectly
provide a relative URL. In this case, it makes more sense to
interpret it relative to the full page URL after redirects, rather
than relative to just the domain part of the page URL before
redirects.

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.
Removes the `/day` and `/night` options from the typeahead menu while
still allowing the commands to be used. Typing `/day` and `/night`
will now suggest `/light` and `/dark`, respectively. Also changes the
`Dark mode` and `Light mode` popups that appear after using the
corresponding command.
Fixes#18318.
Created a schema for the ignored_parameters_unsupported that is
returned by the /settings and /realm/user_settings_defaults endpoints
and removed the duplicated text in the api documentation.
Also cleaned up some small errors in the /realm/user_settings_default
definition and sidebar link /api/update-realm-user-settings-defaults.

Since 3853285241, PushNotificationsWorker uses the aioapns library
to send Apple push notifications. This introduces an asyncio event
loop into this worker process, which, if unlucky, can respond poorly

...which subsequently leads to the worker failing to make any progress
on the queue.
Remove the timeout on the worker. This may result in failing to make
forward progress if Apple/Google take overly long handling requests,
but is likely preferable to failing to make forward progress if _one_
request takes too long and gets unlucky with when the signal comes
through.
This makes logging more consistent between FCM and APNs codepaths, and
makes clear which user-ids are for local users, and which are opaque
integers namespaced from some remote zulip server.
Being able to determine how many distinct users are getting push
notifications per remote host is useful, as is the distribution of
device counts. This parallels the log line in
handle_push_notification for push notifications from local realms,
handled via the event queue.
We should use more selective query for UserGroupMembership
objects in tests for checking adding and removing members.
This is done by checking the membership counts for the
particular user group only.
This will help in keeping the tests more understandable
after we add members to the role-based system groups,
since that would create a lot of membership objects.
We make the UserGroup queries in user group creation and
deletion tests more selective by fitering the user groups
which belong to the realm and not the one included in
lear realm, etc.
This will help us to keep the tests more understandable
when the counts of UserGroup increases due to addition of
system groups. There is no need to consider system groups
of other realms in these tests.
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.
* Remove unnecessary json_validator for full_name parameter.

`rendered_content` in historical messages may be empty; examining the
history of them may thus require diff'ing two empty strings, which
itself produces an empty string.
Use `lxml.html.fragment_fromstring` to be able to successfully parse
these, rather than 500.
Part of #19559.
As detailed in the comments, the default behavior is undesirable for us
because we can't really predict all possibilities of exceptions that may
be raised - and thus putting str(e) in the http response is potentially
insecure as it may leak some unexpected sensitive information that was
in the exception.
As a hypothetical example - KeyError resulting from some buggy
some_dict[secret_string] call would leak information. Though of course
we aim to never write code like that.
We pass allow_realm_admin as True to access_stream_by_id for
`GET users/{user_id}/subscriptions{stream_id}` endpoint
because we want to allow non-subscribed admins to get
subscription status in private streams.
Fixes#19077.
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 makes the query in get_user_group_direct_members
efficient by directly fetching user-profile ids instead of
first fetching user profile object and then id.
The previous commit apparently didn't have its migration attached properly.
Since this is just a reference to a ManyToManyField, this migration
doesn't actually modify the database, but it is needed for CI to pass.
This commit renames members field of UserGroup to direct_members

be able to have a subgroup.
This commit renames get_user_group_members to get_user_group_direct_members
to specify that the function is used only to fetch direct members of group
and excludes the subgroup's members.
Extracted this commit from #19866.

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.
From 430c5cb, in `fetch_initial_state_data`,
we only include legacy settings in the top level of
`state` and the newer ones are stored in `state['user_settings']`.
That should've had a corresponding change in apply_event().
Also, fixed a test related to this logic.
From 430c5cb, we do not send events for settings added after
introduction of `user_settings` event.
This test wasn't considering that and started failing on
adding new user_settings.
This commit removes _test_user_settings_for_adding_streams
and its callers for testing public and private streams
because it uses excessive mocking and we also test the same
thing in _test_user_settings_for_creating_streams without
mocking, so this test doesn't add anything.
For users who are not logged in and for those who don't have
'prefers_web_public_view' set in session, we redirect them
to the default login page where they can choose to login
as spectator or authenticated user.
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.
This commit enforces invite_only argument to be named
in _test_user_settings_for_creating_streams. This will
help in improving readability especially when we will
add is_web_public argument in further commits.
This commit adds tests for POLICY_EVERYONE and POLICY_NOBODY
in check_has_permission_policies test. The original code
used these values but these were not covered in test.
We send three events when changing delivery email of a user - one
for updating the delivery_email field of user, one for avatar url
change, and one for changing email field if email_address_visibility
is set to 'EMAIL_ADDRESS_VISIBILITY_EVERYONE'.
There is already a test for delivery_email and avatar_url event with
the visibility setting set to 'EMAIL_ADDRESS_VISIBILITY_ADMINS_ONLY',
but no test for verifying the email update event sent when email
address is public, so this commit adds a test for checking the schema
of event for updating email field.
When email_address_visibility is changed and either the old value
or the updated value is EMAIL_ADDRESS_VISIBILITY_EVERYONE then
email field of all users is updated and we also send the corresponding
event to clients. But apply_event code did not update the data on
receiving the event, so this commit fixes the code to correctly
handle the event in apply_event.
(We also use this event when just changing a user's email address).
This commit also adds the tests and openapi schema for the event.
We use the lists defined in models.py like Realm.COMMON_POLICY_TYPES,
Realm.COMMON_MESSAGE_POLICY_TYPES, etc. in do_set_realm_property_test
instead of using defining list there (eg - [4, 3, 2, 1]). We do the
same thing in do_set_realm_property_test in test_realm.py.
We skip email_address_visibility values in this commit because it
requires some change in openapi schema as well.
Since the calls to the translation function `_()` are made outside
of the `send_message_moved_breadcrumbs` function, these strings are
translated outside of the `with override_language` block, leading to
translated strings even when we don't intend them to be translated.
We now use gettext_lazy with appropriate testing to avoid this.
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.
This removes a false-positive ReDoS, since the input is always
checked-in code. It also incidentally refactors to make the regexes
be more explicit about the values they expect, and removes unnecessary
capturing groups.
It removes an optional parenthesized status code for fixtures,
unnecessary since 981e4f8946, as well as
optional key-value language options, unnecessary since
a2be9a0e2d.
Thank you to @erik-krogh and @yoff for bringing this to our attention.
This fixes the issue where 'None' would appear in the rendered
html in case of a missing tab display_name. Now,
'test-help-documentation' will fail in case of any tab display_name
being missing.
In case of a tab_section with no tabs, currently a single tab with
the name 'null_tab' gets added. Added the display name 'None' for
'null_tab', to keep in line with the existing behaviour.
Fixes#19822
This makes our onboarding guide for education organizations much
simpler, since new organizations will start with these settings
correctly configured.
Fixes#19682
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 commit does not remove the 'enable_login_emails' field from
RealmUserDefault table but it is just not used and cannot be
changed from UI or API similar to 'enable_marketing_emails' setting.
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 fixes a problem where we could not import zerver.lib.streams from
zerver.lib.message, which would otherwise be reasonable, because the
former implicitly imported many modules due to this issue.
Requests to the root subdomain weren't getting request_notes.realm set
even if a realm exists on the root subdomain - which is actually a
common scenario, because simply having one organization, on the root
subdomain, is the simplest and common way for self-hosted deployments.
This reverts commit cd93d0967f.
This check_or is redundant with check_union; it gives a misleading
error message for the non-matching case; and it has no type safety.
