Creating the QueueProcessingWorker objects when the ThreadedWorker is
created can lead to a race which caused confusing error messages:
1. A thread tries to call `self.worker = get_worker()`
2. This call raises an exception, which is caught by
`log_and_exit_if_exception`
3. `log_and_exit_if_exception` sends our process a SIGUSR1, _but
otherwise swallows the error_.
4. The thread's `.run()` is called, which tries to access
`self.worker`, which was never set, and throws another exception.
5. The process handles the SIGUSR1, restarting.
Move the creation of the worker to when it is started, so the worker
object does not need to be stored, and possibly have a decoupled
failure.
If we `.distinct("delivery_email")` then we must also
`.order_by("delivery_email")`; adc987dc43 added the `.order_by`
call, which broke the newsletter codepath, since it did not contain
the `delivery_email` in the ordering fields.
Add a flag to distinct on emails in `send_custom_email`.
The set of `enable_marketing_emails=True` are those that have opted
into getting marketing newsletter emails -- but we previously limited
further to only those users active in the last month.
Broaden that to "opted in, and either recently active or an owner or
an admin," with the goal of providing information to folks who may
have tried out Zulip in the past.

Saying `**options: str` is a lie, since it contains bools. We pluck
out the two bools that we need properly typed because we will be
pushing them into function calls, and type them explicitly as bools.
We call 'send_server_data_to_push_bouncer' just after registering
server for push notification.
This helps to have a current state of the user counts when first
logging in after the RemoteRealm flow.
This works around the `/usr/bin/pg_dump` failure described in the
previous commit. Since we are now calling the appropriately-versioned
`pg_dump` binary directly, it is no longer "necessary", but is added
as a defense-in-depth.
`/usr/bin/pg_dump` on Ubuntu and Debian is actually a tool which
attempts to choose which `pg_dump` binary from all of the
`postgresql-client-*` packages that are installed to run. However,
its logic is confused by passing empty `--host` and `--port` options
-- instead of looking at the running server instance on the server, it
instead assumes some remote host and chooses the highest versioned
`pg_dump` which is installed.
Because Zulip writes binary database backups, they are sensitive to
the version of the client `pg_dump` binary is used -- and the output
may not be backwards compatible. Using a PostgreSQL 16 `pg_dump`
writes archive format 1.15, which cannot be read by a PostgreSQL 15
`pg_restore`.
Zulip does not currently support PostgreSQL 16 as a server. This
means that backups on servers with `postgresql-client-16` installed
did not successfully round-trip Zulip backups -- their backups are
written using PostgreSQL 16's client, and the `pg_restore` chosen on
restore was correctly chosen as the one whose version matched the
server (PostgreSQL 15 or below), and thus did not understand the new
archive format.
Existing `./manage.py backups` taken since `postgresql-client-16` were
installed are thus not directly usable by the `restore-backup` script.
They are not useless, however, since they can theoretically be
converted into a format readable by PostgreSQL 15 -- by importing into
a PostgreSQL 16 instance, and re-dumping with a PostgreSQL 15
`pg_dump`.
Fix this issue by hard-coding path to the binary whose version matches
the version of the server we are connected to. This may theoretically
fail if we are connected to a remote PostgreSQL instance and we do not
have a `postgresql-client` package locally installed which matches the
remote PostgreSQL server's version. However, choosing a matching
version is the only way to ensure that it will be able to be imported
cleanly -- and it is preferable that we fail the backup process rather
than write backups that we cannot easily restore from.
Fixes: #27160.
Our logic for extracting strings from templates did not properly
handle the syntax for code containing whitespace control characters,
resulting in a couple strings from subscribe_to_more_streams.hbs not
being processed.
This allows us to not have to keep extending the tool for every
one-off use case and set of users; we build a pipeline to generate the
appropriate JSON file, write a template which uses the data it
provides, and run the tool with them together.
The set of objects in the `users` object can be very large (in some
cases, literally every object in the database) and making them into a
giant `id in (...)` to handle the one tiny corner case which we never
use is silly.
Switch the `--users` codepath to returning a QuerySet as well, so it
can be composed. We pass a QuerySet into send_custom_email as well,
so it can ensure that the realm is `select_related` in as well, no
matter how the QuerySet was generated.
