Anders Kaseorg 0ce6dcb905 mypy: Upgrade mypy from 1.4.1 to 1.5.1.
_default_manager is the same as objects on most of our models. But
when a model class is stored in a variable, the type system doesn’t
know which model the variable is referring to, so it can’t know that
objects even exists (Django doesn’t add it if the user added a custom
manager of a different name). django-stubs used to incorrectly assume
it exists unconditionally, but it no longer does.

Zixuan James Li 30495cec58 migration: Rename extra_data_json to extra_data in audit log models.
This migration applies under the assumption that extra_data_json has
been populated for all existing and coming audit log entries.

- This removes the manual conversions back and forth for extra_data
throughout the codebase including the orjson.loads(), orjson.dumps(),
and str() calls.

- The custom handler used for converting Decimal is removed since
DjangoJSONEncoder handles that for extra_data.

- We remove None-checks for extra_data because it is now no longer
nullable.

- Meanwhile, we want the bouncer to support processing RealmAuditLog entries for
remote servers before and after the JSONField migration on extra_data.

- Since now extra_data should always be a dict for the newer remote
server, which is now migrated, the test cases are updated to create
RealmAuditLog objects by passing a dict for extra_data before
sending over the analytics data. Note that while JSONField allows for
non-dict values, a proper remote server always passes a dict for
extra_data.

- We still test out the legacy extra_data format because not all
remote servers have migrated to use JSONField extra_data.
This verifies that support for extra_data being a string or None has not
been dropped.

Zixuan Li e39e04c3ce
migration: Add `extra_data_json` for audit log models.
Note that we use the DjangoJSONEncoder so that we have builtin support
for parsing Decimal and datetime.

During this intermediate state, the migration that creates
extra_data_json field has been run. We prepare for running the backfilling
migration that populates extra_data_json from extra_data.

This change implements double-write, which is important to keep the
state of extra data consistent. For most extra_data usage, this is
handled by the overriden `save` method on `AbstractRealmAuditLog`, where
we either generates extra_data_json using orjson.loads or
ast.literal_eval.

While backfilling ensures that old realm audit log entries have
extra_data_json populated, double-write ensures that any new entries
generated will also have extra_data_json set. So that we can then safely
rename extra_data_json to extra_data while ensuring the non-nullable
invariant.

For completeness, we additionally set RealmAuditLog.NEW_VALUE for
the USER_FULL_NAME_CHANGED event. This cannot be handled with the
overridden `save`.

This addresses: https://github.com/zulip/zulip/pull/23116#discussion_r1040277795

Note that extra_data_json at this point is not used yet. So the test
cases do not need to switch to testing extra_data_json. This is later
done after we rename extra_data_json to extra_data.

Double-write for the remote server audit logs is special, because we only
get the dumped bytes from an external source. Luckily, none of the
payload carries extra_data that is not generated using orjson.dumps for
audit logs of event types in SYNC_BILLING_EVENTS. This can be verified
by looking at:

`git grep -A 6 -E "event_type=.*(USER_CREATED|USER_ACTIVATED|USER_DEACTIVATED|USER_REACTIVATED|USER_ROLE_CHANGED|REALM_DEACTIVATED|REALM_REACTIVATED)"`

Therefore, we just need to populate extra_data_json doing an
orjson.loads call after a None-check.

This adds support to accepting extra_data being dict from remote

servers that have migrated to use JSONField for RealmAuditLog just in
case. This prepares us for migrating zilencer's audit log models to use

The '(num_deleted, ignored) = ModelName.objects.filter().delete()'

We avoid the pattern '(num_deleted, _)' because Django uses _

Alex Vandiver f531f3a27f push_notifications: Drop FCM retries to 2, not 10.
This reverts bc15085098 (which provided
not justification for its change) and moves further, down to 2 retries
from the default of 5.

10 retries, with exponential backoff, is equivalent to sleeping 2^11
seconds, or just about 34 minutes (though the code uses a jitter which
may make this up to 51 minutes).  This is an unreasonable amount of
time to spend in this codepath -- as only one worker is used, and it
is single-threaded, this could effectively block all missed message
notifications for half an hour or longer.

This is also necessary because messages sent through the push bouncer
are sent synchronously; the sending server uses a 30-second timeout,
set in PushBouncerSession.  Having retries which linger longer than
this can cause duplicate messages; the sending server will time out
and re-queue the message in RabbitMQ, while the push bouncer's request
will continue, and may succeed.

Limit to 2 retries (APNS currently uses 3), and results expected max
of 4 seconds of sleep, potentially up to 6.  If this fails, there
exists another retry loop above it, at the RabbitMQ layer (either
locally, or via the remote server's queue), which will result in up to
3 additional retries -- all told, the request will me made to FCM up
to 12 times.

Alex Vandiver 1b395b6403 zilencer: Truncate APNS notifications correctly.
APNs payloads nest the zulip-custom data further than the top level,
as Android notifications do.  This led to APNs data silently never

provided the wrong data for the APNs structure.

Adjust to look in the appropriate place within the APNs data, and
truncate that.

Mateusz Mandera 4153b5c517 remote_server: Improve uuid validation at the server/register endpoint.
As explained in the comments in the code, just doing UUID(string) and
catching ValueError is not enough, because the uuid library sometimes
tries to modify the string to convert it into a valid UUID:

>>> a = '18cedb98-5222-5f34-50a9-fc418e1ba972'
>>> uuid.UUID(a, version=4)

PIG208 dcbb2a78ca python: Migrate most json_error => JsonableError.
JsonableError has two major benefits over json_error:
* It can be raised from anywhere in the codebase, rather than
  being a return value, which is much more convenient for refactoring,
  as one doesn't potentially need to change error handling style when
  extracting a bit of view code to a function.
* It is guaranteed to contain the `code` property, which is helpful
  for API consistency.

Various stragglers are not updated because JsonableError requires
subclassing in order to specify custom data or HTTP status codes.

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
