This change avoids hitting the Django ORM when
we don't find any possible group mentions in
the message content.
Django doesn't necessarily actually hit the database,
but it's still slow and shows up in profiles.
This commit speeds up the import by avoiding
sender lookups and instead using the data
for users that we already have in memory.
This avoids a few DB hops, many hops to memcached,
plus some object construction.
We now call do_render_markdown() directly. This
also makes it more explicit that the import has
never rendered alert words.
For the import-data codepath, we will call
the extracted function directly in a
subsequent commit.
The do_render_markdown() function has more
required parameters, which allows for more
explicit code and also allows us to flatten
out some logic related to alert words. (We
just pass in empty sets/dicts as needed).
We can rely on `message_realm` being the same
as `message.sender.realm`, which allows us to
skip two queries to the database for the rare
Zephyr mirroring case.
This function requires a message object, whereas
we want to work with JSON data to avoid necessary
queries when we import data. Inlining the function
sets us up for a subsequent refactoring.
We change the way we deal with theoretical return
values of `None` to use an assertion; otherwise,
we would have to loosen up a bunch of mypy types
from `str` to `Optional[str]`. It's not clear `None`
is even possible--we've moved toward throwing exceptions
there instead of silently failing.
This is somewhat hairy logic, so it's nice
to extract it and not worry about variable leaks.
Also, this moves some legacy "subject" references out
of actions.py.
We start by including functions that do custom
queries for topic history.
The goal of this library is partly to quarantine
the legacy "subject" column on Message.
Use the placeholder `[Quoting…]` when quoting and replying before the
quote has been added to the message. Also, add tests to the
`compose_actions` Node tests for the new behavior.
Fix#10705.
A recent change to check_send_webhook_message allows webhooks to
unescape stream names before sending a message. This commit adds
a test for the edge case where the webhook URL is escaped twice by
a third-party.
Apparently, we can use the process group naming style of having dashes
in the names without using the explicit nun_procs feature of
supervisord configuration.
The new configuration is perfectly satisfactory, so there's no real
reason to prefer the old approach.
This allows our Tornado monitoring to correctly report whether
multiple configured Tornado processes are running.
This setup isn't ideal, in that it can't detect cases where the wrong
set of Tornado processes are running, but it's nice and simple and
should catch most actual problems.
Recently, one of our users reported that a JIRA webhook was not
able to send messages to a stream with a space character in its
name. Turns out that JIRA does something weird with webhook URLs,
such that escaped space characters (%20) are escaped again, so
that when the request gets to Zulip, the double escaped %20 is
evaluated as the literal characters `%20`, and not as a space.
We fix this by unescaping the stream name on our end before
sending the message forward!
The previous logic was incorrect, in that if `content_type` was set to
None (which happens with Slack/HipChat export, among other things),
then we wouldn't run the `guess_type` logic to auto-detect the
Content-Type to send to S3.
Guest users can't access subscribers of any(public or private)
non-subscribed streams. Therefore, hide subscribers list
of all non-subscribed streams from guest users in UI.
Fixes#10749 (the previous parts were fixed already).
For the PHP link, I just found an equivalent link that detailed
some well-known PHP security vulnerabilities.
As for the now defunct RequestBin, another instance is hosted
by another domain, so we can recommend using that for now.
