Anders Kaseorg e7ed907cf6 python: Convert deprecated Django ugettext alias to gettext.
django.utils.translation.ugettext is a deprecated alias of
django.utils.translation.gettext as of Django 3.0, and will be removed
in Django 4.0.

Cyril Pletinckx b7fa41601d emails: Truncate overly-long From fields for RFC compatibility.
Amazon SES has a limit on the size of address fields, and rejects
emails with too-long "From" combinations of name and address. This
limit is set to 320 bytes and comes from an RFC limitation on the
size of addresses. This RFC standard states that an email address
should not be composed of a local part (before the '@') longer than
64 bytes and a domain part (after the '@') longer than 255 bytes.
It is possible that Amazon SES misinterprets this limitation as it
checks the length of the combination of the name and the email
address of the sender.

To ensure that this problem is not encountered in the send_email
module of Zulip the length of this combination is now checked
against this limit and the from_name field is removed to only
keep the from_address field when it is necessary in order to
stay below 320 bytes.

If the from_address field alone is longer than 320 bytes the
sending process will raise an SMTPDataError exception.

Tests for this new check are added to the backend test suite in
order to test if build_email correctly outputs an email with filled
from_name and from_address fields when the total length is lower
than 320 bytes and that it correctly throws the from_name field
away when necessary.

Fixes: #17558.

Mateusz Mandera d236d3f738 users: Improve db transaction structure in user (de)activation process.
These procedures should be done atomically overall, with the exception
of the code that sends events to avoid block if there's a delay
communicating with Tornado.
We add the savepoint=False on underlying function that already
executes inside an atomic context - to avoid the overhead of creating
savepoints where they aren't needed.

Mateusz Mandera f95dd628bd email: Fix race conditions with concurrent ScheduledEmail handling.
The main race conditions, which actually happened in production was with
concurrent execution of deliver_email and clear_scheduled_emails.
clear_scheduled_emails could delete all email.users in the middle of
deliver_email execution, causing it to pass empty to_user_ids list to
send_email. We mitigate this by getting the list of user ids in a single
query and moving forward with that snapshot, not having to worry about
database data being mutated anymore.

clear_scheduled_emails had potential race conditions with concurrent
execution of itself due to not locking the appropriate rows upon
selecting them for the purpose of potentially deleting them. FOR UPDATE
locks need to be acquired to prevent simultaneous mutation.

Tested manually with some print+sleep debugging to make some races
happen.

Anders Kaseorg 365fe0b3d5 python: Sort imports with isort.
Fixes #2665.

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.

Tim Abbott 703fae8980 send_custom_email: Use a special .gitignored directory.
Previously, the send_custom_email code path leaked files in paths that
were not `.gitignored`, under templates/zerver/emails.

This became problematic when we added automated tests for this code
path, as it meant we leaked these files every time `test-backend` ran.

Fix this by ensuring all the files we generate are in this special
subdirectory.

arpit551 8f7733cb20 emails: Added placeholders strings in FormAddress.
We've had a bug for a while that if any ScheduledEmail objects get
created with the wrong email sender address, even after the sysadmin
corrects the problem, they'll still get errors because of the objects
stored with the wrong format.

We solve this by using FromAddress placeholders strings in
send_future_email function, so that ScheduledEmail objects end up
setting the final `from_address` value when mail is actually sent
using the setting in effect at that time.

Tim Abbott 67981725ec send_email: Fix migration code path for ScheduledEmail.
The previous migration code path was broken in two ways:

* ScheduledEmail objects generally contain a `None` value for
  whichever of `to_user_id` and `to_email` isn't in use; this could
  result in us sending a [None] to send_email(), which doesn't make
  sense.

* We were calling handle_send_email_format_changes in the wrong order
  with respect to the JSON loading process.

Joshua Pan 533eccd655 models: Create delivery_email field in userprofile.
This commit creates a new field called delivery_email. For now, it is
exactly the same as email upon user profile creation and should stay
that way even when email is changed, and is used only for sending
outgoing email from Zulip.

The purpose of this field is to support an upcoming option where the
existing `email` field in Zulip becomes effectively the user's
"display email" address, as part of making it possible for users
actual email addresses (that can receive email, stored in the
delivery_email field) to not be available to other non-administrator
users in the organization.

Because the `email` field is used in numerous places in display code,
in the API, and in database queries, the shortest path to implementing
this "private email" feature is to keep "email" as-is in those parts
of the codebase, and just set the existing "email" ("display email")
model field to be something generated like
"username@zulip.example.com" for display purposes.

Eventually, we'll want to do further refactoring, either in the form
of having both `display_email` and `delivery_email` as fields, or
renaming "email" to "username".
