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.
Otherwise the dummy user can be created with an invalid email domain -
e.g. in development environment with the domain
"@http://localhost:9991". get_fake_email_domain exists exactly for
handling these kinds of scenarios.
get_remote_server_by_uuid (called in validate_api_key) raises
ValidationError when given an invalid UUID due to how Django handles
UUIDField. We don't want that exception and prefer the ordinary
DoesNotExist exception to be raised.
APNs payloads nest the zulip-custom data further than the top level,
as Android notifications do. This led to APNs data silently never
being truncated; this case was not caught in tests because the mocks
provided the wrong data for the APNs structure.
Adjust to look in the appropriate place within the APNs data, and
truncate that.
This replaces the temporary (and testless) fix in
24b1439e93 with a more permanent
fix.
Instead of checking if the user is a bot just before
sending the notifications, we now just don't enqueue
notifications for bots. This is done by sending a list
of bot IDs to the event_queue code, just like other
lists which are used for creating NotificationData objects.
Credit @andersk for the test code in `test_notification_data.py`.
As explained in the comments in the code, just doing UUID(string) and
catching ValueError is not enough, because the uuid library sometimes
tries to modify the string to convert it into a valid UUID:
>>> a = '18cedb98-5222-5f34-50a9-fc418e1ba972'
>>> uuid.UUID(a, version=4)
UUID('18cedb98-5222-4f34-90a9-fc418e1ba972')
It's slightly annoying to plumb Optional[MentionBackend]
down the stack, but it's a one-time change.
I tried to make the cache code relatively unobtrusive
for the single-message use case.
We should be able to eliminate redundant stream queries
using similar techniques.
I considered caching at the level of rendering the message
itself, but this involves nearly as much plumbing, and
you have to account for the fact that several users on
your realm may have distinct default languages (French,
Spanish, Russian, etc.), so you would not eliminate as
many query hops. Also, if multiple streams were involved,
users would get slightly different messages based on
their prior subscriptions.
While accepting an invitation from a user, there was no condition in
place to check if the user sending the invitation was now
now-deactivated.
Skip sending notifications about newly-joined users to users who are
now disabled.
Fixes#18569.
We don't have to go to the database to get the Recipient
fields for `user_profile.recipient`.
See also 85ed6f332a from a little
over a year ago--it's very similar.
The bug here probably didn't come up too much in
practice, but if we were adding a user to multiple
streams when they already had used all N available
colors, all the new streams would be assigned the same
color, since the size of used_colors would stay at N,
thwarting our little modulo-len hackery.
It's not a terrible bug, since users can obviously
customize their stream colors as they see fit.
Usually when we are adding a user to multiple streams,
the users are fairly new, and thus don't have many
existing streams, so I have never heard this bug
reported in the field.
Anyway, assigning the colors in bulk seems to make more
sense, and I added some tests.
For the situations where all the colors have already
been used, I didn't put a ton of thought into exactly
which repeated colors we want to choose; instead, I
just ensure they're different modulo 24. It's possible
that we should just have more than 24 canned colors, or
we should just assign the same default color every time
and let users change it themselves (once they've gone
beyond the 24, to be clear). Or maybe we can just do
something smarter here. I don't have enough time for a
deep dive on this issue.
This commit sets us up for the next commit, which will
save us a very expensive query.
If you are adding 15k users to a stream, and each user
has about 20 existing streams, then we need to retrieve
300k rows from the database to figure out which stream
colors they already have. We don't need all the extra
fields from Subscription, so now we get just the two
values we need for making a color map.
In the next commit we'll eliminate the other use case
for the big query, and I will explain in greater
depth how splitting out the color-picking code can
be a huge win. It is possible that some product decisions
could make this codepath easier. We could also do some
engineering specific to stream colors, such as caching
which colors users have already used.
This does cost us an extra round trip to the database.
Given that these values are uuids, it's better to use UUIDField which is
meant for exactly that, rather than an arbitrary CharField.
This requires modifying some tests to use valid uuids.
Updates testing helpers in `event_schema.py` for `do_update_message` so
that all stream message fields are present in any edits / updates to
stream messages. Adds verfication tests of events returned from private
message edits and from stream message content-only and topic-only edits.
These fundamentally tested send_email, not build_email, and thus
belong in TestSendEmail, not TestBuildEmail. They also duplicated the
code in test_send_email_exceptions; reuse it.
This allows verify_uploads to use the database
as the authoritative source for what attachments
we need to look for when we're verifying the
images got exported properly, while still
also verifying attachment.json is correct.
It is better for the verifying code to just explicitly
ensure that the exported file bytes match the bytes
in the test image. This introduces a tiny bit more
of I/O.
It's easier to read the code without the intermediate
full_data dictionary that obscures where the files live.
We also avoid some unnecessary file i/o in the tests.
We do a sanity check for every table
that gets written to user.json as part of
the single-user export.
If we add more tables to the single-user export,
the test that I modified here will now ask
the author to add a new checker function, which
means we should always have at least a basic
sanity check for every exported table as long
as we stay in this new paradigm.
We also remove a little bit of old code that
became redundant.
This replaces the TERMS_OF_SERVICE and PRIVACY_POLICY settings with
just a POLICIES_DIRECTORY setting, in order to support settings (like
Zulip Cloud) where there's more policies than just those two.
With minor changes by Eeshan Garg.
We do s/TOS/TERMS_OF_SERVICE/ on the name, and while we're at it,
remove the assumed zerver/ namespace for the template, which isn't
correct -- Zulip Cloud related content should be in the corporate/
directory.
We now complain if a test author sends a stream message
that does not result in the sender getting a
UserMessage row for the message.
This is basically 100% equivalent to complaining that
the author failed to subscribe the sender to the stream
as part of the test setup, as far as I can tell, so the
AssertionError instructs the author to subscribe the
sender to the stream.
We exempt bots from this check, although it is
plausible we should only exempt the system bots like
the notification bot.
I considered auto-subscribing the sender to the stream,
but that can be a little more expensive than the
current check, and we generally want test setup to be
explicit.
If there is some legitimate way than a subscribed human
sender can't get a UserMessage, then we probably want
an explicit test for that, or we may want to change the
backend to just write a UserMessage row in that
hypothetical situation.
For most tests, including almost all the ones fixed
here, the author just wants their test setup to
realistically reflect normal operation, and often devs
may not realize that Cordelia is not subscribed to
Denmark or not realize that Hamlet is not subscribed to
Scotland.
Some of us don't remember our Shakespeare from high
school, and our stream subscriptions don't even
necessarily reflect which countries the Bard placed his
characters in.
There may also be some legitimate use case where an
author wants to simulate sending a message to an
unsubscribed stream, but for those edge cases, they can
always set allow_unsubscribed_sender to True.
While races here are unlikely, it is most correct to enforce this
invariant at the database layer, and having a database-level
constraint makes the models file a bit more readable.
We now ensure that all message ids are sorted BEFORE
we split them into batches.
We now do a few extra "slim" queries to get message
ids up front.
But, now, when we divide them into batches, we no
longer run 2 or 3 different complicated queries in
a loop. We just basically hydrate our message ids,
so `write_message_partials` should be easy to reason
about.
This change also means that for tiny realms with
< 1000 messages you will always have just one
json file, since we aggregate the ids from the
queries before batching.
Zulip shows two guides on How to reply, first one by
the welcome bot and second one is intro_reply hotspot.
To simply and avoid redundancy, intro_reply hotspot is
removed.
Fixes#20482.
Force postgres to give reactions in ID order - which
is generally chronological order. Results in frontend
displaying reactions in said order.
Fixes#20060.
Removed existing empty narrow divs from app/home.html and created
a new javascript module to dynamically load empty narrow messages
using handlebar template.
Fixes#18797
The original intention of this was to prevent coding
errors with realm getters that don't, um, filter
on realm.
Unfortunately, you can still write a broken realm getter
that forgets to filter on realm, but which returns a
Set, and the new safeguards won't see any difference.
We could make all the getters return sorted lists
instead, but that's for another day.
This code does serve another purpose, which is to
prevet egregious bugs in the import itself.
The diff here is ugly, but to summarize:
BEFORE IMPORT:
define get_user_id
define get_huddle_hashes
AFTER IMPORT AND MAKING GETTERS:
check realm id
define assert_realm_values
verify emoji codes
check huddle hashes
The comment explains in more detail, but basically we'd skip
exercising a bit of code in the signup code path if there were no
messages in the last week, resulting in the query count not matching.
