Fixes#25414.
We add Attachment.scheduled_messages relation to track ScheduledMessages
which reference the attachment.
The import bits can be done after merging this, by updating #25345.
This implements the core of the rewrite described in:
For the backend data model for UserPresence to one that supports much
more efficient queries and is more correct around handling of multiple
clients. The main loss of functionality is that we no longer track
which Client sent presence data (so we will no longer be able to say
using UserPresence "the user was last online on their desktop 15
minutes ago, but was online with their phone 3 minutes ago"). If we
consider that information important for the occasional investigation
query, we have can construct that answer data via UserActivity
already. It's not worth making Presence much more expensive/complex
to support it.
For slim_presence clients, this sends the same data format we sent
before, albeit with less complexity involved in constructing it. Note
that we at present will always send both last_active_time and
last_connected_time; we may revisit that in the future.
This commit doesn't include the finalizing migration, which drops the
UserPresenceOld table.
The way to deploy is to start the backfill migration with the server
down and then start the server *without* the user_presence queue worker,
to let the migration finish without having new data interfering with it.
Once the migration is done, the queue worker can be started, leading to
the presence data catching up to the current state as the queue worker
goes over the queued up events and updating the UserPresence table.

So far, we've used the BitField .authentication_methods on Realm
for tracking which backends are enabled for an organization. This
however made it a pain to add new backends (requiring altering the
column and a migration - particularly troublesome if someone wanted to
create their own custom auth backend for their server).
Instead this will be tracked through the existence of the appropriate
rows in the RealmAuthenticationMethods table.
Black 23 enforces some slightly more specific rules about empty line
counts and redundant parenthesis removal, but the result is still
compatible with Black 22.
(This does not actually upgrade our Python environment to Black 23
yet.)

On multi-realm systems this results in traversal of all messages in
all realms and returns a massive payload of 1 row per stream on
the server, not the intended one row per realm.
This guarantees that the Realm is always non-None when we hit the
codepath is_static_or_current_realm_url via
do_change_stream_description, so that we can properly skip rewritting
some images.

On my data (about 10 million messages in 1600 streams) this used to take
about 40 hours, while the improved statement completes in roughly 30
seconds.
The old solution had postgres go through the entire table until the
first match for each stream. Thus, the time spent scanning the table
got longer and longer for each stream because postgres always started at
the beginning (and somehow it did not use any indices) and had to skip
over all rows until it found the first message from the stream that is
was looking for each time.
This new statement just performans a bulk operation, scanning the table
only once and then inserts the results directly into the destination
table.

These were useful as a transitional workaround to ignore type errors
that only show up with django-stubs, while avoiding errors about
unused type: ignore comments without django-stubs. Now that the
django-stubs transition is complete, switch to type: ignore comments
so that mypy will tell us if they become unnecessary. Many already
have.

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.
This commit sets can_remove_subscribers_group to admins system
group while creating streams as it will be the default value
of this setting. In further we would provide an option to set
value of this setting to any user group while creating streams
using API or UI.
We change the import order to import UserGroup objects before
Stream such that we can set can_remove_subscribers_group correctly.
We do not import UserGroupMembership objects here along with
UserGroup since UserProfile objects are not imported and
GroupGroupMembership are also imported later as these are not
required before.
We do not need direct_members and direct_subgroups field of
UserGroup objects in the export data since we already have
UserGroupMembership and GroupGroupMembership object data.
While importing we keep these fields empty when creating
UserGroup objects and direct_members and direct_subgroups
fields will get set when UserGroupMembership and
GroupGroupMembership objects are created.
This change will also help us in further changes when we
will change the order of importing to import UserGroup
objects just after Realm objects.
Technically recipient_id cannot be None when recipient exists. We
actually just want to check if the recipient exists.

This code is actually a noop (and would be a bug if it wasn't a noop),
because when this runs the server is already initialized, meaning the
internal realm exists and the system bots have been created, so
UserProfile.objects.filter(email=email) is always truthy. Also, system
bots are supposed to live in the internal realm, not in the realm being
imported so this code doesn't make sense currently.
We now use FULL_MEMBERS_GROUP_NAME instead of
writing the actual full members system group
name at multiple places, so that we can have
all the group names coded at one place only.
Previously, we had a function named create_add_users_to_system_user_groups
for creating system user groups and adding users to them in case when
exports do not contain these groups when importing from other services.
This commit just separates out the call to create_system_user_groups_for_realm
outside the function and the function is thus renamed to
add_users_to_system_user_group. This change is done because in further
commits we would need to update the import order and user groups will
be created before creating user profile objects.
`_cache` is not an attribute defined on `BaseCache`, but an

This matches the metadata that we store in the database, and means
that the S3 metadatata invariant of always having a `user_profile_id`
in the metadata.
This does not fix existing imports, which may still have missing
`user_profile_id`s.
There can be cases when system groups data is not present while
importing, like when importing from other products, so this
commit adds code to create system user groups and add users to
it according to their role.
Sometimes we may get data to import, due to export bugs, malformed data
etc., which doesn't have the invariant of RealmEmoji.author always being
set. The import code should fix that, by choosing a reasonable default
and setting it.
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 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.

Because we create all realms with do_create_user (including in the
test suite), we just need to change that function, add a migration for
existing realms, and ensure the data import code path correctly
creates these objects.
Note that the import code path will create a RealmUserDefault row with
default values if it is not present in the import data, which is
important for importing data from other tools like Slack.
This way, we no longer have to manually keep the upload path code in
sync with the upload path code in zerver/lib/upload.py.
This was originally suggested in
https://github.com/zulip/zulip/pull/19478#issuecomment-911479530.
This change fixes a bug when importing into a server using the local
file uploads backend, where the `import_realm.py` copy wasn't using
our standard 256-directory approach to avoid putting too many files in
a single directory.
This adds a new class called MessageRenderingResult to contain the
additional properties we added to the Message object (like alert_words)
as well as the rendered content to ensure typesafe reference. No
behavioral change is made except changes in typing.
This is a preparatory change for adding django-stubs to the backend.
Related: #18777
While importing a realm, the stream dictionaries in data['zerver_stream']
already contains the field named `rendered_description`, which is set to
`""`. This lead the code to assume that the stream rendered_description
was already set, due to which, it was not setting the rendered_description
field for any stream.
The command:
codespell --skip='./locale,*.svg,./docs/translating,postgresql.conf.template.erb,.*fixtures,./yarn.lock,./docs/THIRDPARTY,./tools/setup/emoji/emoji_names.py,./tools/setup/emoji/emoji_map.json,./zerver/management/data/unified_reactions.json' --ignore-words=codespell_ignore_words.txt .

`ensure_basic_avatar_image` and `ensure_medium_avatar_image` are
essentially the same thing, except a size parameter.
So, refactor them into a single function.
This doesn't introduce any functional changes.
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.
This adds the is_user_active with the appropriate code for setting the
value correctly in the future. In the following commit a migration to
backfill the value for existing Subscriptions will be added.
To ensure correct user_profile.is_active handling also in tests, we
replace all direct .is_active mutation with calls to appropriate
functions.
This prevents the memcached connection from being shared across
multiple processes, and hopefully addresses unexpected behavior from
cached functions like get_user_profile_by_id invoked inside the worker
processes.

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.)

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.
Prior to this commit whenever convert was imported from zerver.lib.markdown
it was aliased as markdown_convert for readability.
This commit rename convert function to markdown_convert so that it can be
directly import it without aliasing and without compromising readability.
This commit is first of few commita which aim to change all the
bugdown references to markdown. This commits rename the files,
file path mentions and change the imports.
Variables and other references to bugdown will be renamed in susequent
commits.

Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.
Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start. I expect this change will increase pressure for us to split
those files, which isn't a bad thing.
