This is intended for rare situations where one is creating multiple
realms via a script.
After all the preparatory refactoring in this last several commits, we
can now provide a working implementation of a create_realm management
command.
We set nocoverage for the new function. Ideally it'd eventually get an
automated test, but we don't want to block this helpful refactoring on
doing so.
We remove a bit of error handling for cases where someone provided
only one of the email and full name parameters, with the benefit of
this being a lot cleaner.
This parameter was introduced in
ea11ce4ae6, and no longer serves a
purpose. Zulip will already correctly record that the user has not
agreed to ToS, and either prompt them on first login or not depending
whether the server is configured to require ToS.
This is an important design detail, so we document this aspect of
creating users via both the management command and API code paths with
an explicit parameter value and comment.
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.
The correct return type of get_realm_domains should
be List[Dict[str, Union[bool, str]]] instead of
List[Dict[str, str]] because allowed_subdomains is
a bool field not str.
This was only used for upgrading from Zulip < 1.9.0, which is no
longer possible because Zulip < 2.1.0 had no common supported
platforms with current main.
If we ever want this optimization for a future migration, it would be
better implemented using Django merge migrations.

When pulling batches out of the ScheduledEmail list in a single
transaction, an unexpected failure to send an email will result in the
whole batch getting retried. This will result in infinite email
sending loops.
Pull a single row off at a time and send it. We continue without
retries to the next email on EmailNotDeliveredException, but will
retry infinitely on other exceptions.
Fixes: #20943.
The tool needs to run this function, since it uses django's send_email
directly instead of going through our zerver.lib.send_email.send_email
codepath.
Django 3.2 expects a list, and Django 4.1 will require one. Fixes
“RemovedInDjango41Warning: Using a boolean value for
requires_system_checks is deprecated. Use '__all__' instead of True,
and [] (an empty list) instead of False.”

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.
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.
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
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.
