do_send_messages has side effects outside the database and may not
work reliably if its database effects are reordered by being inside a
transaction.
This also fixes a bug where we were doing the update incorrectly on
the Message table.

SIGALRM is the simplest way to set a specific maximum duration that
queue workers can take to handle a specific message. This only works
in non-threaded environments, however, as signal handlers are
per-process, not per-thread.
The MAX_CONSUME_SECONDS is set quite high, at 10s -- the longest
average worker consume time is embed_links, which hovers near 1s.
Since just knowing the recent mean does not give much information[1],
it is difficult to know how much variance is expected. As such, we
set the threshold to be such that only events which are significant
outliers will be timed out. This can be tuned downwards as more
statistics are gathered on the runtime of the workers.
The exception to this is DeferredWorker, which deals with quite-long
requests, and thus has no enforceable SLO.

We call build_message_send_dict from check_message instead of
do_send_messages.
This is a prep commit for adding a new setting for handling
wildcard mentions in large streams.
We display the text of the consent message, and then continue with the
export, which will scroll the content off the screen. Allow the
administrator time to examine the contents of the message, and decide
whether to proceed based on that and the fraction of users that have
responded so far.
`zproject/settings.py` itself is mostly-empty now. Adjust the
references which should now point to `zproject/computed_settings.py`
or `zproject/default_settings.py`.
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.)

The exception trace only goes from where the exception was thrown up
to where the `logging.exception` call is; any context as to where
_that_ was called from is lost, unless `stack_info` is passed as well.
Having the stack is particularly useful for Sentry exceptions, which
gain the full stack trace.
Add `stack_info=True` on all `logging.exception` calls with a
non-trivial stack; we omit `wsgi.py`. Adjusts tests to match.
The S3 data export tool's upload code path uses this nice boto
callback feature for showing a progress bar, which is nice for the
management command. It's spammy/broken in production and the backend
tests, so we change percent_callback to be a parameter passed in so
that it can only be used in the contexts where it makes sense.
A few major themes here:
- We remove short_name from UserProfile
and add the appropriate migration.
- We remove short_name from various
cache-related lists of fields.
- We allow import tools to continue to
write short_name to their export files,
and then we simply ignore the field
at import time.
- We change functions like do_create_user,
create_user_profile, etc.
- We keep short_name in the /json/bots
API. (It actually gets turned into
an email.)
- We don't modify our LDAP code much
here.
Added new Event Type in AbstractRealmAuditLog STREAM_CREATED.
Since we finally create streams in create_stream_if_needed function
in zerver/lib/streams.py so logged realm_audit there.
Passed acting_user when create_stream_if_needed or ensure_stream
function is called.
Added tests in test_audit_log.
A generator that yields values without receiving or returning them is
an Iterator. Although every Iterator happens to be iterable, Iterable
is a confusing annotation for generators because a generator is only
iterable once.

Fixes#14960.
The default of 6 thread may not be appropriate in certain
configurations. Taking half of the numer of CPUs available to the
process will be more flexible.
