This avoids an error when a user has already muted the new topic name.
We do this by ignoring duplicates, rather than catching the
IntegrityError, because this edit happens in a transaction, and that
would abort the transaction.
Our original implementation of moving muted topic records when a topic
is moved took a shortcut of treating all change_later usage as
something with intent to move the whole topic.
This works OK when moving the whole topic via this interface, but not
when moving a last off-topic message in the topic.
Address this by changing the rule to match the existing
moved_all_visible_messages variable.
Previously, Attachment.is_realm_public and its cousin,
Attachment.is_web_public, were properties that began as False and
transitioned to True only when a message containing a link to the
attachment was sent to the appropriate class of stream, or such a link
was added as part of editing a message.
This pattern meant that neither field was updated in situations where
the access permissions for a message changed:
* Moving the message to a different stream.
* Changing the permissions for a stream containing links to the message.
This correctness issue has limited security impact, because uploaded
files are secured both by a random URL and by these access checks.
To fix this, we reformulate these fields as a cache, with code paths
that change the permissions affecting an attachment responsible for
setting these values to the `None` (uncached) state. We prefer setting
this `None` state over computing the correct permissions, because the
correct post-edit permissions are a function of all messages
containing the attachment, and we don't want to be responsible for
fetching all of those messages in the edit code paths.
Add support for moving MutedTopic entries to another stream where
the user has access to shared history in both streams and
`propagate_mode != "change_one"`.
Also, we delete them the current user does not have access to the
target stream.
We now call this function inside do_create_user(...,
realm_creation=True), which generally improves readability and
robustness of the codebase.
This fixes a bug where this onboarding content was not correctly done
when creating a realm via LDAP, and also will be important as we add
new code paths that might let you create a realm.
This improves robustness of any code paths calling do_create_realm,
which previously needed to call this correctly to achieve the same
results as creating a user via the UI.
This also fixes a bug where this code was not called if a realm were
created using the LDAP code path.
Previously, when a topic was edited (including being resolved), it
would become unmuted for any users who had muted it, which was
annoying.
While it's not possible to determine the user's intent completely,
this is clearly incorrect behavior in the `change_all` case, such as
resolving a topic.
The comments discuss some scenarios where we might want to enhance
this further, but this is the best we can do without large increases
in complexity.
Fixes#15210.

This commit adds the backend functionality to
mark messages as unread through update_message_flags
with `unread` flag and `remove` operation.
We also manage incoming events in the webapp.
Tweaked by tabbott to simplify the implementation and add an API
feature level update to the documentation.
This commit was originally drafted by showell, and showell
also finalized the changes. Many thanks to Suyash here for
the main work here, which was to get all the tests and
documentation work moving forward.
This commit creates a new TypedDict RealmPlaygroundDict for realm
playground objects. Now the list of playgrounds in the events sent
to clients and the "added_playground" field of RealmAuditLog entry
use RealmPlaygroundDict instead of Dict.
This commit modifies the notify_realm_playgrounds function to accept
realm_playgrounds as argument from the caller instead of computing it
in the function to avoid duplicate queries since the realm playgrounds
list will be required in its caller functions as well in further commits.
Clearing the sessions inside the transaction makes Zulip vulnerable to
a narrow window where the deleted session has not yet been committed,
but has been removed from the memcached cache. During this window, a
request with the session-id which has just been deleted can
successfully re-fill the memcached cache, as the in-database delete is
not yet committed, and thus not yet visible. After the delete
transaction commits, the cache will be left with a cached session,
which allows further site access until it expires (after
SESSION_COOKIE_AGE seconds), is ejected from the cache due to memory
pressure, or the server is upgraded.
Move the session deletion outside of the transaction.
Because the testsuite runs inside of a transaction, it is impossible
to test this is CI; the testsuite uses the non-caching
`django.contrib.sessions.backends.db` backend, regardless. The test
added in this commit thus does not fail before this commit; it is
merely a base expression that the session should be deleted somehow,
and does not exercise the assert added in the previous commit.
This commit adds a cron job which runs every hour to add the users to
full members system group if user is promoted to a full member.
This should ensure that full member status is available no more than
an hour after configuration suggests it should be.
This commit adds users to the appropriate system user group
based on their role. We also change the user groups when
changing role of the user.
We also add migration to add existing users to the appropriate
user groups.
This commit adds update_users_in_full_members_system_group which
is currently used to update the full members group on changing
role of a user. This function will be modified in next commit such
that it can be used to update full members group on changing
waiting_period_threshold setting of realm.
We pass list of user ids instead of user profile objects to
remove_members_from_user_group. We still need to call user_id_to_users
in the views function instead of directly passing the ids to
remove_members_from_user_group to make sure we check whether all
ids are valid or not.
We pass list of user ids instead of user profile objects to
bulk_add_members_to_user_group. We still need to call user_id_to_users
in the views function instead of directly passing the ids to
bulk_add_members_to_user_group to make sure we check whether all
ids are valid or not.
A user can subscribe to a stream and sometimes (depending
on stream permissions) see messages from the stream
that were sent before they subscribed, and that user
won't have a UserMessage row for that message.
In order to do things like star a message, we need
to create UserMessage records on the fly.
In the past we wisely constrained this logic to the
specific use cases. But I think we can generalize
the logic now. For example, we are now building a
feature to mark messages as unread, and it motivates
the same need to auto-create UserMessage rows.
So now we handle this in a more generalized fashion.
Translators found it confusing, since it's not at all obvious that the
word "quote" should not be translated.
I'm not altogether happy with the code formatting for this.
While we're changing this, also standardize on the "```` quote" style
of quote blocks to ensure code/quote blocks in stream descriptions are
unlikely to conflict with this syntax.
Now that we have code to support reading prev_topic, this is no longer
necessary.
We'll want to deploy this change to production before running the
migration to remove prev_subject from edit history entries, so that
prev_subject can be fully purged from the database.
We modify the message_edit_history marshalling code so that this
commit does not change the API, since we haven't backfilled the data
yet.
FormattedEditHistoryEvent, introduced in the previous commit, doesn't
directly inherit fields from EditHistoryEvent, so no changes are
required there.
These types will help make iteration on this code easier.
Note that `user_id` can be null due to the fact that
edit history entries before March 2017 did not log
the user that made the edit, which was years after
supporting topic edits (discovered in test deployment
of migration on chat.zulip.org).

The database value for expiry_date is None for the invite
that will never expire and the clients send -1 as value
in the API similar to the message retention setting.
Also, when passing invite_expire_in_days as an argument
in various functions, invite_expire_in_days is passed as
-1 for "Never expires" option since invite_expire_in_days
is an optional argument in some functions and thus we cannot
pass "None" value.
Putting all of the logic in a `finally` block is equivalent to a bare
`except` block, which silently consumes all exceptions.
Move only the most-necessary parts into the except; this lets
`BadImageError` exceptions from `zerver/lib/upload.py` to escape,
allowing better the generic "Image file upload failed" to be replaced
with a more specific message.
It also allows unexpected exceptions, as the previous commit resolved,
to escape and 500. This lets them be detected and resolved, rather
than give users a silently bad experience.
For aliases that will no longer be listed, see the third column of
grep '^L ' zulip-py3-venv/lib/python3.*/site-packages/pytz/zoneinfo/tzdata.zi
Time zones previously set to an alias will be canonicalized on demand.

The new logic better matches reasonable user expectations, that if you
move all the messages, that's a whole-topic move, regardless of which
propagation mode you selected.
When moving only part of a topic, it's useful to display that
information to users in these notifications so that it's clear what's
happening.
The most important consequence is actually just increasing confidence
that when you see that the whole topic was moved, that's accurate.
Substantially modified by tabbott.
Fixes#20575.
Previously, we only checked mandatory_topics setting before
sending message in frontend and there was no restriction in
backend. This commit adds the check in backend also making
sure messages without topic cannot be sent through API as
well if mandatory_topics setting is set to True.
