Anders Kaseorg df001db1a9 black: Reformat with Black 23.
Black 23 enforces some slightly more specific rules about empty line
counts and redundant parenthesis removal, but the result is still
compatible with Black 22.

(This does not actually upgrade our Python environment to Black 23
yet.)

Alex Vandiver 23f4cde91c email_mirror: Ensure that attachments get space to be included.
The content of a message is truncated to `MAX_MESSAGE_LENGTH`, which
is 1000 characters.  Since the email gateway places attachments at the
very end of the extracted body, that means that they are the first
thing to get truncated off.

That is, if an incoming email message contains 1000 `a`s and an image
attachment, the link that attaches the attachment to the message will
get truncated off, leaving it dangling in the database.

Truncate the message body content separately from the attachment links
which are included at the end of the body.

Alex Vandiver 608c787c52 email_mirror: Create attachments as the message sender.
When the email mirror gateway is sending messages "as" a user (as
triggered by having access to the missed-message email address),
attachments were still created as the Email Gateway bot.  Since the
sender (the end-user) was not the owner of those attachments (the
gateway bot), nor were they referenced yet anywhere, this resulted in
the attachments being "orphaned" and not allowed to be accessed by
anyone -- despite the attachment links being embedded in the message.
This was accompanied by the error:

```
WARN [] User 12345 tried to share upload 123/3LkSA4OcoG6OpAknS2I0SFAQ/example.jpf in message 123456, but lacks permission
INFO [zerver.lib.email_mirror] Successfully processed email from user 12345 to example-stream
```

We solve this by creating attachment objects as the users the message
will be sent from.

Jason Hildebrand 7efd59b6d7 email_mirror: Remove limits (expiry, max uses) to improve usability.
These limits don't appear to provide useful security benefits, and
they do impact usability because they prevented email-based users from
replying more than once, or from replying to message more than 5 days
old.

Fixes #2755.

Anders Kaseorg bd9a1dc971 tests: Consistently JSON-encode ‘to’ parameter
Although our POST /messages handler accepts the ‘to’ parameter with or
without JSON encoding, there are two problems with passing it as an
unencoded string.

Firstly, you’d fail to send a message to a stream named ‘true’ or
‘false’ or ‘null’ or ‘2022’, as the JSON interpretation is prioritized
over the plain string interpretation.

Secondly, and more importantly for our tests, it violates our OpenAPI
schema, which requires the parameter to be JSON-encoded.  This is
because OpenAPI has no concept of a parameter that’s “optionally
JSON-encoded”, nor should it: such a parameter cannot be unambiguously
decoded for the reason above.

Our version of openapi-core doesn’t currently detect this schema
violation, but after the next upgrade it will.

This implements get_mandatory_secret that ensures SHARED_SECRET is

it's best to just modify it appropriately.

Zixuan James Li 426f8ce385 tests: Replace `HttpResponse` with `TestHttpResponse.`
Since `HttpResponse` is an inaccurate representation of the
monkey-patched response object returned by the Django test client, we
replace it with `_MonkeyPatchedWSGIResponse` as `TestHttpResponse`.

This replaces `HttpResponse` in zerver/tests, analytics/tests, coporate/tests,
zerver/lib/test_classes.py, and zerver/lib/test_helpers.py with
`TestHttpResponse`. Several files in zerver/tests are excluded
from this substitution.

This commit is auto-generated by a script, with manual adjustments on certain
files squashed into it.

This is a part of the django-stubs refactorings.

Mateusz Mandera 4102816240 upload: Pass the target realm to create_attachment.
The target realm was not being passed to create_attachment in
upload_message_file implementations. This was a bug in the edge-case of
cross-realm messages - in particular, causing a bug in the email
gateway:
When an email with an attachment is sent, the message is mirrored to
Zulip with Email Gateway Bot as the message sender and uploader of the
attachment. Due to the realm not being passed to create_attachment, the
Attachment would get created with .realm being the system bot realm,
making the attachment inaccessible under some conditions due to failing
the following condition check (that's expected to pass, provided that
the .realm is set correctly):
```
    if (
        attachment.is_realm_public
        and attachment.realm == user_profile.realm
        and user_profile.can_access_public_streams()
    ):
        # Any user in the realm can access realm-public files
        return True
```

Eeshan Garg c30458e174 streams: Add notifications for posting policy changes.
An explanatory note on the changes in zulip.yaml and
curl_param_value_generators is warranted here. In our automated
tests for our curl examples, the test for the API endpoint that
changes the posting permissions of a stream comes before our
existing curl test for adding message reactions.

Since there is an extra notification message due to the change in
posting permissions, the message IDs used in tests that come after
need to be incremented by 1.

This is a part of #20289.

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.
