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 1b692984ce slack_incoming: Support "fields" in "section"s.
This is a best-effort rendering of the "fields" of Slack incoming
hooks, which Slack renders in two columns.  We approximate them in a
Markdown table, with some minor in-place replacements.

Fixes #22228.

Alex Vandiver 4dc57dadd6 slack_incoming: Make check_text_block return its input.
`check_text_block` transformed its input, making the object it
returned not the same object it was passed; this invalidated it for
use in `check_list`.  It is also, in general, unlike all other
validators.

Make it return a TypedDict cast of its input.

Alex Vandiver f1a8209705 slack_incoming: Fix formatting fixups with overlaps, or at start/end.
The previous regular expression required a `[^\w]` at the start and
end of the match.  This had two unintended effects -- it meant that it
could never match at the start or end of a string, and it meant
that *adjacent* words required *two* non-word characters between them,
as the pattern matches cannot overlap.

Switch to allowing string start/end to anchor the matches, and make
the trailing `[^\w]` be a zero-width look-ahead, to allow the patterns
to overlap.  Also remove the spurious `^` within the inner character
classes, which prevented `*foo^bar*` from matching.  Finally, add
tests to cover the functionality, which was previously untested.

Hari Prashant Bhimaraju fd0b013bcd slack_incoming: Handle optional attachment fields aptly.
This commit checks for null values for keys within "attachment" in
the Slack integration's incoming payloads. These keys were expected
to exist optionally previously, and the existence of null values for
these wasn't anticipated. Due to an issue report for such null
values in the payload, their handling is updated appropriately.

The checks for these values are truthiness checks since the strategy
for these values being null or falsy ("", 0) is the same; we don't
process that key-value pair. This is consistent with how Slack handles
this scenario.

For the case where all the attachment fields have null values, Slack
displays this as an empty block with no content, and therefore our
strategy for this is a no-op.

Tests updated.

Alex Vandiver bc25f016fc slack_incoming: Support more syntax.
This significantly extends the accepted support for Slack "blocks"[1], as
well as their legacy "attachments"[2] syntax.

Fixes: #21944.

See also #22228, which this does not solve, but assuming we can decide
which compromises to make, becomes a reasonably uncomplicated follow-up.

Christopher Chong b6f6f6db8d slack_incoming: Process request payload directly in view.py.
slack_incoming webhook previously used has_request_variables to
extract payload from HttpRequest object first, before trying to
access HttpRequest.body again in view.py. This caused an error
when one sends a request without payload - it is forbidden to
read from request data stream twice.

Instead of relying on has_request_variables, this PR extracts
payload depending on content type in view.py directly to avoid
reading request data stream twice.

Fixes #19056.

PIG208 5ecbfecd77 webhook: Rename FIXTURE_DIR_NAME to WEBHOOK_DIR_NAME.
Since FIXTURE_DIR_NAME is the name of the folder that contains the view

store the fixtures, it is more appropriate to call it WEBHOOK_DIR_NAME,
especially when we want to refer to the view module using this variable.

Steve Howell 388053db6b webhook tests: Rename main helper to check_webhook.
Almost all webhook tests use this helper, except a few
webhooks that write to private streams.

Being concise is important here, and the name
`self.send_and_test_stream_message` always confused
me, since it sounds you're sending a stream message,
and it leaves out the webhook piece.

We should consider renaming `send_and_test_private_message`
to something like `check_webhook_private`, but I couldn't
decide on a great name, and it's very rarely used.  So
for now I just made sure the docstrings of the two
sibling functions reference each other.

Anders Kaseorg d0f4af5f8c python: Catch JSONDecodeError instead of ValueError when decoding JSON.
These weren’t wrong since orjson.JSONDecodeError subclasses
json.JSONDecodeError which subclasses ValueError, but the more
specific ones express the intention more clearly.

(ujson raised ValueError directly, as did json in Python 2.)

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.

Chris Heald c80e913c7a webhooks: Add a webhook capable of parsing Slack payloads.
This adds a webhook that can be used to interpret standard Slack
payloads. Since there are a ton of existing Slack integrations out
there, having a webhook which can accept standard Slack payloads can
significantly ease transition pains. Obviously this can't do everything
that Slack payloads can (particularly WRT their widgets/interactions),
but we can ingest text and parse out multi-block payloads into a message
relatively reasonably.
