8e10ab282a moved UnexpectedWebhookEventType into
`zerver.lib.exceptions`, but left the import into
`zserver.lib.webhooks.common` so that webhooks could continue to
import the exception from there.
This clutters things and adds complexity; there is no compelling
reason that the exception's source of truth should not move alongside
all other exceptions.
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.
fixes #zulip-2k (sentry)
There are three functional side effects:
• Correct an insignificant but mathematically offensive bias toward
repeated characters in generate_api_key introduced in commit
47b4283c4b4c70ecde4d3c8de871c90ee2506d87; its entropy is increased
from 190.52864 bits to 190.53428 bits.
• Use the base32 alphabet in confirmation.models.generate_key; its
entropy is reduced from 124.07820 bits to the documented 120 bits, but
now it uses 1 syscall instead of 24.
• Use the base32 alphabet in get_bigbluebutton_url; its entropy is
reduced from 51.69925 bits to 50 bits, but now it uses 1 syscall
instead of 10.
(The base32 alphabet is A-Z 2-7. We could probably replace all of
these with plain secrets.token_urlsafe, since I expect most callers
can handle the full urlsafe_b64 alphabet A-Z a-z 0-9 - _ without
problems.)

Improved responsiveness of message reactions tooltip .
Added css property for the reaction tooltip in ./static/js/click_handlers.js so that the tooltip doesn't exceed the sidebar .
Adressed a comment in #15364 .
Wait for disable_stream_notifications selector to be visible
before clicking as it could cause flakes if the test tries
to click without it being visible.
Added a stronger validation of waiting for text "Verona" to
appear but that didn't really seem to have worked though it
seemed like fixing the flake by passing ~600 runs.
So, change the puppeteer click to a click through evaluate
as we had experiences where page.click() didn't work sometimes.
Though this has passed 1000 runs on CI, I'm not very certain
if this fixed it as this test passed 1000 times with my previous
PR fixing the same flake.
Compose box placeholder text for streams currently updates when focus
is shifted to the text area.
With this change, it will also get updated when the stream name is
changed (it already updates if topic names are changed).
Currently, compose box placeholder text for PMs only gets updated
when the focus shifts to it.
With this change, the text is now also updated if recipients are
added or removed.
Fixes#15897.
Previously, onPillCreate function was called after the individual
pill object was created.
Now, we call it after creating and adding it to the pill container.
For web-public streams, clients can access full topic history
without being authenticated. They only need to additionally
send "streams:web-public" narrow with their request like all
the other web-public queries.
This verifies that we actually do enqueue a record when there is an
error on non-staging. With the previous commit, it verifies that that
data serializes correctly.
By default, the Django Sentry integration provides the email address
and username of pulled from the auth layer. This is potentially PII,
and not data that we wish to store. Enable sending user data at all,
by setting `send_default_pii=True`, but strip the username and
email (which are the same, in Zulip) before sending. Users will be
identified in Sentry only by their IP address, user ID, realm, and
role.
The return type of `ugettext_lazy('...')` (aliased as `_`) is a
promise, which is only forced into a string when it is dealt with in
string context. This `django.utils.functional.lazy.__proxy__` object
is not entirely transparent, however -- it cannot be serialized by
`orjson`, and `isinstance(x, str) == False`, which can lead to
surprising action-at-a-distance.
In the two places which will serialize the role value (either into
Zulip's own error reporting queue, or Sentry's), force the return
value. Failure to do this results in errors being dropped
mostly-silently, as they cannot be serialized and enqueued by the
error reporter logger, which has no recourse but to just log a
warning; see previous commit.
When we do this forcing, explicitly override the language to be the
realm default. Failure to provide this override would translate the
role into the role in the language of the _request_, yielding varying
results.
AdminNotifyHandler is used to notify admins of errors; it is a
critical piece of logic. Failures in reporting errors will compound,
since its `except Exception` clauses cannot generate logging at the
`error` or `exception` level, as that would be recursive. It must
settle for logging at the `warning` level, and hope that admins are
vigilant to the logging there.
Increase the chances of being notified of failures in this logger, by
bubbling up those exceptions to Sentry, which is an orthogonal
reporting stack.
When user requests for a realm that doesn't exists, we raise
a InvalidSubdomainError.
This reduces our effort at repeatedly ensuring realm is valid
in request in web-public queries.
