We followed a same approach as in #22611 to mark migrations as noops. We
might eventually squash them.
Migration operations that only change the validators should be removed
as they are essentially noops that do not affect the database schema.
However, ./manage.py makemigration still generates a new migration for
validators change regardless. So we still have to keep one migration
that updates the validators to the latest state. We prefer to keep the
earliest one for this purpose.

This commit adds the OPTIONAL .realm attribute to Message
(and ArchivedMessage), with the server changes for making new Messages
have this set. Old Messages still have to be migrated to backfill this,
before it can be non-nullable.
Appropriate test changes to correctly set .realm for Messages the tests
manually create are included here as well.

SCIMClient is a type-unsafe workaround for django-scim2’s conflation
of SCIM users with Django users. Given that a SCIMClient is not a
UserProfile, it might as well not be a model at all, since it’s only
used to satisfy django-scim2’s request.user.is_authenticated queries.
This doesn’t solve the type safety issue with assigning a SCIMClient
to request.user, nor the performance issue with running the SCIM
middleware on non-SCIM requests. But it reduces the risk of potential
consequences worse than crashing, since there’s no longer a
request.user.id for Django to confuse with the ID of an actual
UserProfile.

We are no longer writing to or reading the UserStatus.status field,
so we delete that from the model.
Fifth step in making user status `away` a deprecated way to access
`presence_enabled` for clients supporting older servers.
Part of transitioning from 'unavailable' user status feature to
'invisible mode' user presence feature.
Now that user status updates with `away=True|False` also update the
user's presence_enabled setting, we do a migration so that users with
`UserStatus.status=AWAY` also have the presence_enabled setting as
False (`away=!presence_enabled`).
Second step in making user status away a deprecated way to access
presence_enabled for clients supporting older servers.
Part of transitioning from 'unavailable' user status feature to
'invisible mode' user presence feature.
To allow `custom_profile_field` to display in user profile popover,
added new boolean field "display_in_profile_summary" in its model class.
In `custom_profile_fields.py`, functions are edited as per conditions,

`LONG_TEXT` and `USER` type fields.
Default external account custom profile fields made updatable for only
this new field, as previous they were not updatable.

Updates the two UserProfile foreign key fields to have a backward

This commit udpates can_remove_subscribers_group to be not null.
We already added a migration to set the value of this field for

admins system group for now while creating streams.
This migration sets can_remove_subscribers_group value to admins system
group for all the existing streams. In further commit we would change
can_remove_subscribers_group to be not null and thus we add this migration
to ensure all existing streams have this setting value set.

This commit changes the code to consider zero as an invalid value for
message_content_edit_time_limit_seconds. Now to represent the setting that
user can edit the message anytime, the setting value will be "None" in
database and "unlimited" will be passed to API from clients.
Since validators do not affect the database, this migration is a noop.
Removing the migration fails check-database-compatibility. We might
eventually delete it when Django supports a cleaner method for deletion.

There may be some internal realms which were created after applying
"0382_create_role_based_system_groups.py" migration and this migration
is used to create system groups for those realms.
Because Django's ContentType objects are, by default, created lazily
when an actual object is created that will use them, this migration
would fail on any server that actually had RealmReactivationStatus
objects already, and had not yet created the ContentType for them.
ContentType objects are very simple:
zulip=> select * from django_content_type where model = 'realmreactivationstatus';
id | app_label | model
----+-----------+-------------------------
85 | zerver | realmreactivationstatus
So we can simply patch this by using get_or_create.
We now send a new user_topic event while muting and unmuting topics.
fetch_initial_state_data now returns an additional user_topics array to
the client that will maintain the user-topic relationship data.
This will support any future addition of new features to modify the
relationship between a user-topic pair.
This commit adds the relevent backend code and schema for the new
event.
Now that we can assume Python 3.6+, we can use the
email.headerregistry module to replace hacky manual email address
parsing.

A user ran into an issue while upgrading where
ContentType.objects.get(model="realmreactivationstatus",
app_label="zerver") fails due to the object being missing. The reason
for that is to be yet figured out, but the immediate solution is clear
in the sense that the migration can just quit early
if not Confirmation.objects.filter(type=REALM_REACTIVATION).exists() and
that'll effectively skip it for almost all servers (because realm
reactivations links are something that's really only useful on Zulip
Cloud).
Fixes#21266.
We want to tie the prereg_user to the MultiUseInvite directly rather
than to the MultiUserInvite's confirmation object, because the latter is
not possible. This is because the flow is that after going through the
multiuse invite link, the PreregistrationUser is created together with a
Confirmation object, creating a confirmation link (via
create_confirmation_link) to which then the user is redirected to finish
account creation. This means that the PreregistrationUser is already
tied to a Confirmation, so that attribute is occupied.
PostgreSQL's `default_statistics_target` is used to track how many
"most common values" ("MCVs") for a column when performing an
`ANALYZE`. For `tsvector` columns, the number of values is actually
10x this number, because each row contains multiple values for the
column[1]. The `default_statistics_target` defaults to 100[2], and
Zulip does not adjust this at the server level.
This translates to 1000 entries in the MCV for tsvectors. For
large tables like `zerver_messages`, a too-small value can cause
mis-planned query plans. The query planner assumes that any
entry *not* found in the MCV list is *half* as likely as the
least-likely value in it. If the table is large, and the MCV list is
too short (as 1000 values is for large deployments), arbitrary
no-in-the-MCV words will often be estimated by the query planner to
occur comparatively quite frequently in the index. Based on this, the
planner will instead choose to scan all messages accessible by the
user, filtering by word in tsvector, instead of using the tsvector
index and filtering by being accessible to the user. This results in
degraded performance for word searching.
However, PostgreSQL allows adjustment of this value on a per-column
basis. Add a migration to adjust the value up to 10k for
`search_tsvector` on `zerver_message`, which results in 100k entries
in that MCV list.
PostgreSQL's documentation says[3]:
> Raising the limit might allow more accurate planner estimates to be
> made, particularly for columns with irregular data distributions, at
> the price of consuming more space in `pg_statistic` and slightly
> more time to compute the estimates.
These costs seem adequate for the utility of having better search.
In the event that the pgroonga backend is in use, these larger index
statistics are simply wasted space and `VACUUM` computational time,
but the costs are likely still reasonable -- even 100k values are
dwarfed by the size of the database needed to generate 100k unique
entries in tsvectors.

This commit removes "role" field from subscription

This commit removes WILDCARD_MENTION_POLICY_STREAM_ADMINS
option of wildcard_mention_policy since we are not moving
forward with stream administrator concept and instead working
on new permssions model as per #19525.
We also add a migration to change wildcard_mention_policy of
existing realms to WILDCARD_MENTION_POLICY_ADMINS. This change
is fine since we were already treating both the setting values
as same as stream admin concept was not implemented completely.
This was removed in Django 4.0 except in historical migrations. We
might as well replace it everywhere.

The default of a Stream is to be public - having
history_public_to_subscribers default to False is inconsistent with
that. The defaults on the model should generally be consistent.
history_public_to_subscribers wasn't explicitly set when creating
streams via build_stream, thus relying on the model's default of False.
This lead to public streams being created with that value set to False,
which doesn't make sense.
We can solve this by inferring the correct value based on invite_only in
the build_stream funtion itself - rather than needing to add a flag
argument to it.
This commit also includes a migration to fix public stream with the
wrong history_public_to_subscribers value.
Fixes#21784.
Added a setting to the bottom of Settings > Display settings > Theme section
to display the reacting users on a message when numnber of reactions are
small.
This is a preparatory commit for #20980.
This is necessary for the migration 0386_fix_attachment_caches to run,
and likely makes more convenient any future parallel code interacting
with both Attachment and ArchivedAttachment.
This migration needs to be run after the previous commit is deployed
to a given Zulip installation, to fix any stale values of
is_realm_public and is_web_public.
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.
* Don't print the empty list for the vast majority of realms where
this is a noop.
* Make output a little more clear that this isn't revoking all
Confirmations, just those associated with deactivated users.
he possibility for it being null was likely an oversight -- it should
have been removed after the early migrations to backfill the field
when it was added.
We've confirmed there are no existing violations of this invariant in
Zulip Cloud.
This is a natural follow-up to
93e8740218 - invitations sent by users
deactivated before the commit still need to be revoked, via a
migration.
The logic for finding the Confirmations to deactivated is based on
get_valid_invite_confirmations_generated_by_user in actions.py.
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.
This is in a separate commit to make deployment easier. It ensures that
this is only marked non-null after the backfill migration (backfilling
.uuid for all old UserProfiles) runs - which was added in the previous
commit.
This model is by designed intended to exist on a 1:1 relationship with
Realms, and we attempt to ensure that with application code, but we
should have a unique constraint too, since a database with duplicate
such entries would be corrupted.
We do this via the standard Django OneToOneField.
A migration should not import zerver.lib.streams at all, but this
solves the immediate problem with check-database-compatibility.py.

The deferred_work events can't be processed in the test suite
environment, since it tries to make requests to the host <realm.uri>
which is "zulip.testserver" and obviously not going to work. Since the
test suite base data set has no animated emoji, there's nothing to do,
and we can skip this step.
This code only runs when applying the migration to an already
provisioned test db - because during an initial db set up there are no
realms yet, so no events get pushed by the migration.
Under the unicodedata distributed with Python 3.6, some Emoji are
classified as `Cn`, and not `So`:
```
$ unicode 1f929 --long
U+1F929 GRINNING FACE WITH STAR EYES
UTF-8: f0 9f a4 a9 UTF-16BE: d83edd29 Decimal: 🤩 Octal: \0374451
🤩
Category: So (Symbol, Other); East Asian width: W (wide)
Unicode block: 1F900..1F9FF; Supplemental Symbols and Pictographs
Bidi: ON (Other Neutrals)
$ python3.6 -c 'import unicodedata; print(unicodedata.category("\U0001f929"))'
Cn
$ python3.7 -c 'import unicodedata; print(unicodedata.category("\U0001f929"))'
So
```
Drop `Cn` from the list of excluded Unicode character classes, and
replace it with an explicit list of the 66 non-characters, which are
invariant.

do_delete_users had two bugs:
1. Creating the replacement dummy users
with active=True
2. Creating the replacement dummy users with email domain set to
realm.uri, which may not be a valid email domain.
Prior commits fixed the bugs, and this migration fixes the pre-existing
objects.
While races here are unlikely, it is most correct to enforce this
invariant at the database layer, and having a database-level
constraint makes the models file a bit more readable.
Following b3c58f454f, we want to clean up
old topics that may contain the disallowed characters. The Message table
is large, so we go in batches, making sure we limit topic fetches and
UPDATE query to no more than BATCH_SIZE Message rows per query.
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.
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.
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.
