It doesn't make sense to run sync_ldap_user_data if user_profiles list
is empty. Otherwise this misleading exception gets raised:
```
raise Exception(
"LDAP sync would have deactivated all users. This is most likely due "
"to a misconfiguration of LDAP settings. Rolling back...\n"
"Use the --force option if the mass deactivation is intended."
)
```
With some work by tabbott to manage the type of user_profiles and
provide a special error message for the empty server case.
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.
This adds the X-Smokescreen-Role header to proxy connections, to track
usage from various codepaths, and enforces a timeout. Timeouts were
kept consistent with their previous values, or set to 5s if they had
none previously.
This is a roundabout way to appease a semgrep complaint about
‘error_msg = error_msg % (string_id,)’ while also improving the code.

The ability to use multiple ports has been removed a long time ago.
And the "optional" note in the help message is in fact incorrect
since `addrport` being `None` is not supported.
The auth attempt rate limit is quite low (on purpose), so this can be a
common scenario where a user asks their admin to reset the limit instead
of waiting. We should provide a tool for administrators to handle such
requests without fiddling around with code in manage.py shell.
Only clear_scheduled_emails previously took a lock on the users before
removing them; make deliver_scheduled_emails do so as well, by using
prefetch_related to ensure that the table appears in the SELECT. This
is not necessary for correctness, since all accesses of
ScheduledEmailUser first access the ScheduledEmail and lock it; it is
merely for consistency.
Since SELECT ... FOR UPDATE takes an UPDATE lock on all tables
mentioned in the SELECT, merely doing the prefetch is sufficient to
lock both tables; no `on=(...)` is needed to `select_for_update`.
This also does not address the pre-existing potential deadlock from
these two use cases, where both try to lock the same ScheduledEmail
rows in opposite orders.
These checks suffer from a couple notable problems:
- They are only enabled on staging hosts -- where they should never
be run. Since ef6d0ec5ca, these supervisor processes are only
run on one host, and never on the staging host.
- They run as the `nagios` user, which does not have appropriate
permissions, and thus the checks always fail. Specifically,
`nagios` does not have permissions to run `supervisorctl`, since
the socket is owned by the `zulip` user, and mode 0700; and the
`nagios` user does not have permission to access Zulip secrets to
run `./manage.py print_email_delivery_backlog`.
Rather than rewrite these checks to run on a cron as zulip, and check
those file contents as the nagios user, drop these checks -- they can
be rewritten at a later point, or replaced with Prometheus alerting,
and currently serve only to cause always-failing Nagios checks, which
normalizes alert failures.
Leave the files installed if they currently exist, rather than
cluttering puppet with `ensure => absent`; they do no harm if they are
left installed.
This is effectively a step closer to what was proposed in
https://github.com/zulip/zulip/pull/18678#discussion_r644490540 when
this code was written in #18678.
If the Customer object has neither of a Stripe id, nor any historical
plans, then there's no real billing association contained in the
existence of the Customer object, and it's safe to delete.
This commit allows to import the following from rocketchat:
* All users
* All public/private channels
* All teams and its public/private channels
* All discussion rooms as topics in their parent channel
* All the messages in all the channels
* All private conversations
* Reactions on messages (except for custom emojis)
* Mentions in messages (except @all, @here mentions)
Zulip identifies users by realm+delivery_email which means that the
Django changepassword command doesn't work well -
since it looks only at the .email field.
Thus we fork its code to our own change_password command.
Commit 81d7dd1fda broke this nearly
eight years ago, so probably nobody cares except the ever-watchful eye

This command was part of the complex migration to introduce the
`unread_msgs` data structure as the source of truth for unreads.
Effectively, it's a migration to remove anomalies that we ran several
times before turning it into the final 0104_fix_unreads.py migration.
Fixes part of #18898.
This command is part of a statsd infrastructure that we stopped
supporting years ago. Its only purpose for some time has been to
provide sample code for how the restart script might trigger a
notification to a graphing system, which doesn't justify maintaining
it.
Fixes part of #18898.
This command was part of early prototyping of the digests feature, and
in particular its purpose is better served via the organization-level
setting to control digest emails for the organization.

This command was written to allow generating multiuse invite links
before the "Invite a user" UI supported them. It no longer has a

Fixes part of #18898.
This command predates there being a normal UI for inviting users to
Zulip. It no longer has a role for which it's a better way to do
things. (Especially with upcoming API documentation for the endpoint).
Fixes part of #18898.
This command was introduced in 2013 via
6d6c3364dc as part of implementing
marking messages as read in a separate process for performance reasons.
We fixed the performance issues and removed that pipeline years ago,
but forgot to delete this.
Fixes part of #18898.
Sometimes the Slack import zip file we get isn't quite the canonical
form that Slack produces -- often because the user has unzip'd it,
looked at it, and re-zip'd it, resulting in extra nested directories
and the like.
For such cases, support passing in a path to an unpacked Slack export
tree.
The `create_user` API and data import tools can result in our having
active users in the database who haven't intentionally created a Zulip
account or agreed to the ToS; we should never email such users.
The check for `TOS_VERSION is not None` is necessary for the
development environment, which has `TERMS_OF_SERVICE` set but not
`TOS_VERSION`.
It's likely that we will want this check in other places as well.
`deliver_scheduled_emails` and `deliver_scheduled_messages` use their
respective tables like a queue, but do not have guarantees that there
was only one consumer (besides the EMAIL_DELIVERER_DISABLED setting),
and could send duplicate messages if multiple consumers raced in
reading rows.
Use database locking to ensure that the database only feeds a given
ScheduledMessage or ScheduledEmail row to a single consumer. A second
consumer, if it exists, will block until the first consumer commits
the transaction.
This makes it parallel with deliver_scheduled_messages, and clarifies
that it is not used for simply sending outgoing emails (e.g. the
`email_senders` queue).
This also renames the supervisor job to match.
