A few internal fields used for tracking which types of notifications
have already been sent for a given message, like `hander_id` and the
`push_notified` bundle of fields were being incorrectly included in
message events delivered to clients clients.
One could argue these fields might be useful hints to clients, but
because notifications can be triggered later on via
`missedmessage_hook`, they have no useful purpose in the API.
This commit move these extended event field on a `internal_data`
object within the event object, and delete this field in `contents()`
for call points that would serve data to clients.
Tweaked by tabbott to provide a cleaner interface.
We're not bumping API_FEATURE_LEVEL because these fields have always
been documented as being present only due to a bug, so no clients
should be expecting or relying on them.
Fixes: #15947.
user_profile.id was confused for user_profile.recipient_id. These bugs
are particularly sneaky as they can go undetected by tests due to ids of
objects accidentally coinciding. We add a mitigation for this class of
mistakes by shifting the Recipient.id sequence in test db.
This was introduced in dda3ff41e1.
On the rare occasion where user_profile.id would coincide with
recipient_id passed to the function, we would return the wrong value.
That is, instead of correctly returning recipient_id, we would return
sender.recipient_id - recipient id of the sender of the message, thus
possibly returning user_profile.recipient_id (if user_profile is the
sender) - exactly the situation the function wanted to avoid
with the `if recipient_id == my_recipient_id:` if. Ultimately resulting
in incorrect/malformed data in
state['raw_recent_private_conversations'].
nlargest is the natural fit for selecting n biggest items
from an unsorted list. It's more readable as well as more
efficent (even though we don't care much about the efficeny
in this particular case).
The current logic doesn't display data types when the additionalProperties
variables are not object, but are array of strings, etc. Changed the if
condition to allow rendering in such cases.
zerver/lib/users.py has a function named access_user_by_id, which is
used in /users views to fetch a user by it's id. Along with fetching
the user this function also does important validations regarding
checking of required permissions for fetching the target user.
In an attempt to solve the above problem this commit introduces
following changes:
1. Make all the parameters except user_profile, target_user_id
to be keyword only.
2. Use for_admin parameter instead of read_only.
3. Adds a documentary note to the function describing the reason for
changes along with recommended way to call this function in future.
4. Changes in views and tests to call this function in this changed
format.
Changes were tested using ./tools/test-backend.
Fixes#17111.
Previously, the data type of responses wasn't displayed in the API

The responses for the API weren't being rendered from yaml, and were
incorrectly formatted in yaml. The parameters also weren't completely
included in yaml and needed to be moved. Made appropriate fixes in
yaml and markdown file.

This commit migrates some of the backend tests to use assertLogs(),
instead of mock.patch() as planned in #15331.
Tweaked by tabbott to avoid tautological assertions.
There were some tests that had mock patches for logging, although no
logging was actually happening there. This commit removes such patches
in `corporate/tests/test_stripe.py`, `zerver/tests/test_cache.py`,
`zerver/tests/test_queue_worker.py`,
and `zerver/tests/test_signup.py`.
EmailLogBackend used to create a new EmailMessage and copy
only certain values from the original EmailMultiAlternatives
object. This resulted in the loss of information and made
it harder to test PRs like
https://github.com/zulip/zulip/pull/17121.
So instead of creating a new EmailMessage, tweak and send the existing
EmailMultiAlternatives object.
Depending on PostgreSQL’s query plan, it was possible for the value

The changes are as follows:
• Fix one day offset in all western zones.
• Correct CST from -64800 to -21600 and CDT from -68400 to -18000.
• Disambiguate PST in favor of -28000 over +28000.
• Add GMT, UTC, WET, previously excluded for being at offset 0.
• Add ACDT, AEDT, AKST, MET, MSK, NST, NZDT, PKT, which the previous
code did not find.
• Remove numbered abbreviations -12, …, +14, which are unnecessary.
• Remove MSD and PKST, which are no longer used.
Hardcode the dict and verify it with a test, so that future
discrepancies won’t go silently unnoticed.

When we were getting an apply_event call for
a subscription/add event, we were trying not to
mutate the event itself, but this clumsy code
was still mutating the actual event:
# Avoid letting 'subscribers' entries end up in the list
for i, sub in enumerate(event['subscriptions']):
event['subscriptions'][i] = \
copy.deepcopy(event['subscriptions'][i])
del event['subscriptions'][i]['subscribers']
This is only a theoretical bug.
The only person who receives a subscription/add
event is the current user.
And it wouldn't have affected the current user,
since the apply_event was correctly updating the
state, and we wouldn't actually deliver the event
to the client (because the whole point of apply_event
is to prevent us from having to piggyback the
super-recent events on to our payload or put
them into the event queue and possibly race).
The new code just cleanly makes a copy of each
sub, if necessary, as we add them to state["subscriptions"].
And I updated the event schemas to reflect that
subscribers is always present in subscription/add
event.
Long term we should probably avoid sending subscribers
on this event when the clients don't set something
like include_subscribers. That's a fairly complicated
fix that involves passing in flags to ClientDescriptor.
Alternatively, we could just say that our policy is
that we never send subscribers there, but we instead
use peer_add events. See issue #17089 for more
details.
It's always cleaner to work in id space. It probably
would have required a perfect storm to have broken
the existing code, but using ids is obviously more
robust in theory, and just as simple.
We now require keywords, so that there is no
pitfall for mixing up boolean parameters.
Positional parameters are basically evil
when you have a bunch of bools.
I also make user_profile the first argument.
Finally, the code is more diff-friendly.
I eliminate the defaults, since the existing code
was already specificying values for most things.
I move all the booleans to the bottom for both
parameters and arguments.
I require explicit keywords for everything but
user_profile (which is now first).
And, finally, I format the code in a more
diff-friendly manner.
We eliminate some redundant checks.
We also consistently provide a `subscribers` field
in our stream data with `[]`, even if our users
can't access subscribers. We therefore bump
the API version and tweak the docs. (See further
down for a detailed justification of the change.)
Even though it is sometimes fine to have redundant code
that is defensive in nature, some upcoming changes are gonna
move subscriber-related logic out of build_stream_dict_for_sub
for certain codepaths as part of our effort to streamline
the payload for subscribers within page_params.
So we can't rely on the code that I removed here
inside of build_stream_dict_for_sub.
Anyway, it makes more sense to do these checks explicitly
in the validate function.
The code in build_stream_dict_for_sub was almost effectively
a noop, since the validation function was already preventing
us from getting subscriber info. The only difference it
made was sometimes converting `[]` to `None`, and then
subsequently omitting the subscribers field.
Neither ZT nor the webapp make any distinction between
`[]` or <missing key> for the `subscribers` data in
`page_params`.
The webapp has had this code for a long time (and now
equivalent code elsewhere in this PR):
if (!Object.prototype.hasOwnProperty.call(sub, "subscribers")) {
sub.subscribers = new LazySet([]);
}
The webapp calculates access based on booleans, anyway:
sub.can_access_subscribers =
page_params.is_admin || sub.subscribed ||
(!page_params.is_guest && !sub.invite_only);
And ZT would choke if `subscribers` were missing, except that
it never gets to the relevant code due to other checks:
def get_other_subscribers_in_stream(<snip>):
assert stream_id is not None or stream_name is not None
if stream_id:
assert self.is_user_subscribed_to_stream(stream_id)
return [sub
for sub in self.stream_dict[stream_id]['subscribers']
if sub != self.user_id]
else:
return [sub
for _, stream in self.stream_dict.items()
for sub in stream['subscribers']
if stream['name'] == stream_name
if sub != self.user_id]
You could make a semantic argument that we should prefer
<missing key> to `[]` when subscribers aren't even available, but
we have precedent from the way that `bulk_get_subscriber_user_ids`
has traditionally populated its result:
result: Dict[int, List[int]] =
{stream["id"]: [] for stream in stream_dicts}
If we changed `stream_dicts` to `target_stream_dicts` we
would faciliate a move toward `None`, but it would just cause
headaches for other server code as well as the frontends
(which, to reiterate, already prefer the empty array
for convenience).
As my comment indicates, I would prefer to handle
this explicitly by raising JsonableError in an
else statement here, but it's not a big deal.
This function can probably be simplified with a
bit of work, mostly on the testing side to make
sure we are covering all edge cases, but that
is out of the scope of my current PR.
By moving the relevant logic from realm.get_bot_domain to
get_fake_email_domain we will make realm.host be used (if possible) for
dummy user addresses. That is, instead of user11@zulipchat.com, the
address will become user11@subdomain.zulipchat.com.
With the change in d70e1bcdb7,
bots get email like bot@zulip.com with EXTERNAL_HOST="zulip.com",
rather than bot@subdomain.zulip.com, which was the old format. That's
not desirable, so with this commit, realm.host will be used when
possible and only falling back to FAKE_EMAIL_DOMAIN if needed.
We often send only one field (away or status_text)
to be updated.
So we have to make our schema support optional
keys.
As a result of the more flexible schema, we no
longer need to exempt the node fixtures from
our schema checks.
Since recipient_id (id of the PERSONAL Recipient of the user) was
denormalized into the UserProfile model, this query can be simplified by
getting rid of the zerver_recipient JOIN.
This makes us more efficient when handling
multiple users. We don't have to keep
sending the same two queries to the database.
Note that as part of this we eliminated
a failure mode for the obscure population
of users from whom both `user.is_guest` and
`user.can_access_public_streams()` returns
False. We know this would have only affected
Zephyr users (by looking at the code), and
we know we don't actually process Zephyr
users for email digests (or else we would
have raised exceptions in the old code).
We mostly need realm_id, but when we go to build
message lists, we need realm.uri.
We could probably be more aggresive about using
`only` here, but for now I am just trying to
reduce hops to the database.
The `deployment` key was only set in `do_report_error`, which is now
only used in one codepath (the queue worker). The logging handlers on
staging call notify_server_error directly, which omits the
`deployment` key.
Remove the odd one-of key, and instead simply do dispatch in
`do_report_error`.
The codepath for moving a topic changes the message.recipient_id to the
id of the new recipient, but later, in update_messages_for_topic_edit,
it uses message.recipient when querying for messages with the matching
topic in the *old* stream (because those are the other messages that
need to be moved). This is a bug which happens to work fine, because in
Django 2, if message.recipient gets fetched first and then
message.recipient_id is mutated, message.recipient will not be altered
and thus will retain the outdated, previously fetched value.
In Django 3 changing .recipient_id causes .recipient to be updated to
the new Recipient objects, which is the Recipient of the *new* stream.
That will cause the bug to manifest.
This is a bugfix preparing for the upgrade to Django 3.
Support for saving it in the session is dropped in django3, the cookie
is the mechanism that needs to be used. The relevant i18n code doesn't
have access to the response objects and thus needs to delegate setting
the cookie to LocaleMiddleware.
Fixes the LocaleMiddleware point of #16030.
We now require explicit keywords for all arguments
to fetch_initial_state_data except user_profile.
We provide reasonable defaults to keep the test
code concise.
In the case of reusing a registration link, reuse the
redirect_to_email_login_url helper. This does have the side effect of
now showing a "you've already registered" note, which did not happen
previously, but that seems probably for the best, since the user did
just click a "register" link.
ecfafc05c0 shifted to using a different paramter name to hint that
the user had previously signed up -- and in so doing also stopped
pre-filling the "email" box. Also send along the email box, to save
users time.
Checking for `validate_email_not_already_in_realm` again (after the
form already did so), but only in the case that the form fails to
validate, means that we may be spending time pushing totally invalid
emails to the DB to check. In the case of emails containing nulls,
this can even trigger a 500 error from PostgreSQL.
Stop calling `validate_email_not_already_in_realm` in the form
validation. The form is currently only used in two places -- in
`accounts_home` and in `maybe_send_to_registration`. The latter is
only called if the address is known to not currently have an account,
so checking in there is unnecessary; and in the former case, we wish
different behaviour (the redirect) than just validation failure, which
is all the validator can do.

Add a `--allow-reserved-subdomain` flag which allows creation of
reserved keyword domains. This also always enforces that the domain

Fixes#16924.
When changing the subdomain of a realm, create a deactivated realm with
the old subdomain of the realm, and set its deactivated_redirect to the
new subdomain.
Doing this will help us to do the following:
- When a user visits the old subdomain of a realm, we can tell the user
that the realm has been moved.
- During the registration process, we can assure that the old subdomain
of the realm is not used to create a new realm.
If the subdomain is changed multiple times, the deactivated_redirect
fields of all the deactivated realms are updated to point to the new
uri.
Instead of just storing the edit history in the message which
triggered the topic edit, we store the edit history in all
the messages that changed. This helps users track the edit history
of a message more reliably.
This change updates the GitHub Integration webhook
get_opened_or_update_pull_request_body method so that
the description is only printed if it actually changes.

description is not included in the message sent to
the zulip stream.

Allowing any admins to create arbitrary users is not ideal because it
can lead to abuse issues. We should require something stronger that

can_create_users permission.
We change the return type of check_message to be dataclass instead of
Dict[str, Any]. This refactoring helps us to understand the context of the
data structure returned by check_message clearly which was not possible
when using Dict.
SendMessageRequest class is added in zerver/lib/message.py inspite of it
not being used in that file itself just to maintain consistency as other
TypedDicts and dataclasses are defined in that file and to avoid circular
dependency as SendMessageRequest is being used in lib/widget.py as well.
We also rename local variable to 'send_request' for accessing
SendMessageRequest objects.
The {addr} part isn't directly useful, since connections to Tornado
are done on localhost anyway, and made the development environment
output a bit more confusing.
Also, use the same phrasing for restarts we use for Django.
This logging is really only potentially interesting in a development
environment when the numbers are nonzero.
In production, it seems worth logging for consistency reasons.
Probably we'll eventually redo this block by change the log level, but
this is good enough to despam the development environment startup
output.
We always want to do these at the same time. Previously, message
editing did too much stripping (fixes#16837) and failed to check for

Previously we were just returning a dict containing a message id when
trying to mirror a already sent message in 'zephyr_mirror' cases.
This commit changes this behaviour to raise an exception when trying
to mirror an already sent message by adding a new exception class
ZephyrMessageAlreadySentException and then the caller returns the
message_id directly, instead of calling do_send_messages which also
returns a list of size one containing the message_id only.
This is a prep commit for changing the return type of check_message to
be a dataclass instead of a Dict as now we have only single output for
check_message.
This commit renames the content variable in do_widget_post_save_actions
to message_content and is a prep commit for changing the return type of
check_message from Dict to dataclass.
This change is required because content variable is used two times in
this function - one for message content and other for submessage
content, so when we change the return type of check_message to
dataclass, the type of content variable is considered as str and then
when dict is assigned to content in the submessage case, mypy raises
'Incompatible types in assignment' error.
This issue is not faced before the dataclass migration because there is
no type checking for the values of dict returned by check_message as the
return type of check_message is 'Dict[str, Any]'.
The message_dict['wildcard_mention_user_ids'] should be empty set instead
of empty list when there are no wildcard mentions similar to the case
when there are wildcard mentions, where it is equal to set of user ids and
not list of user ids.

If a user visits a realm which has been deactivated and it's

This simplifies the code, as it allows using the mechanism of converting

For 3000 messages and 400 users, this saved
about 30 seconds.
We only do two queries per batch of messages
now, and the algorithm is easier to analyze,
as it's just three nested loops.
Note that we are much more efficient about finding
active users here:
- we do one query per realm (instead of per-user)
- we pass the cutoff date to the database
- we get back just a list of distinct ids
This function is going away completely soon. It is
querying everybody's entire UserActivity history instead
of passing the cutoff date to the database!
The query counts increase here for somewhat
contrived reasons. The tests before this
commit reflected a successful trip to the
UserProfile cache, but that's not actually
realistic in practice.
We don't need to mock the dates here. We also
explicitly clear out all streams first, and then
we explicitly test with both the stream being
current and the stream being old.
We can use the _enqueue_emails_for_realm helper
to avoid all the Tuesday-related logic here.
We also don't bother to create UserActivity
records, since the bot gets excluded by virtue
of its being a bot. (Also, the date ranges
here were sketchy due to the time mocking.)
We can avoid all the date mocking now for all
but a couple tests that exercise the is-it-Tuesday
logic.
And this test now correctly tests that we exclude
recently active users.
And this allows us to remove the other test.
Sentry allows adding simple webhooks without going through the process
of creating an Internal Integration in Sentry's Integration
Platform[1] (which our docs recommend).
The payload from sent from such a (simple) webhook integration is

webhook. This commit tries to wrangle this payload into a form that is

This fixes a bug introduced in

was adjacent to the others that needed it in the file.
Fix this, and add tests to verify that things are still being escaped
once after removing this extra escape.
Fixes#14845.
The code we deleted here was no longer
doing anything.
Maybe the code was always dead, or maybe it
was written during a time when topics_by_diversity
and topics_by_length actually had different keys.
But now it's clearly cruft.
If we have 4 or more topics, then the code above
it would already have populated the list with 4
elements, and the `if num_convos < 4` condition
would evaluate to False.
And if we had 3 or fewer topics, then we would
have already put all possible topics into our
result, and the `topics_by_diversity[num_convos:4]`
slice would be empty.
It's possible that we should just have a simple
heuristic for topic hotness like `10*num_senders
+ messages`, so we don't have to maintain this
fiddly function, and we can just do something like
`topics_by_score[:4]`.
I now use sets for stream_ids in more of the digest
code.
As part of this I replaced exclude_subscription_modified_streams
with streams_recently_modified_for_user.
It's easier for the caller to just ask for ids
to delete from its callee than it is to pass
in a set/list to mutate.
The simpler boundary between the functions makes
the tests easier to write--you can see the
`filtered_streams` logic goes away in this diff.
I also make the tests a bit more thorough by using
combinations of Cordelia/Othello and Verona/Denmark
to try to find multiple possible flaws.
And I make the time intervals longer than 1s to
avoid false negatives from slow CI boxes.
If we have multiple users, this reduces the amount
of queries we need to do, because we get all
subscriptions for all users in a single query
to Subscription.
For the single-user case, we are introducing an
extra query hop, but the database is doing
roughly the same work, because we are just breaking
up this complex query into two hops:
messages =
select ... from message
where recipient__type_id in (
select stream_id from subscription
where ...
)
Now it's more like:
stream_ids =
select stream_id from subscription
where ...
messages =
select ... from message
where recipient__type_id in stream_ids
Note that we are not changing anything semantically
or algorithmically yet. The only overhead here
for the single-user case is boxing and unboxing
data into single-item dicts and lists.
The interfaces for callers in the view and the
queue processor remain the same for now.
We didn't need the enough-traffic mock.
We also continue to prep for testing multiple users.
I also finally remove a comment that is about to
be addressed (and which inaccurately refers to huddles).
This extraction will make a bit more sense when
we start doing bulk operations on a realm to
get digests, but even now, it encapsulates the
slightly complex way we cherry-pick the top 4
topics for a user.
This prep step is mostly for diff hygiene; the next
commit will make the code a bit nicer.
The original code here had the nice property that
most (but not all) of the DB work happened up
front in `handle_digest_email`, and none of the
DB work was delegated to the callers. But I
prefer the tradeoff of making the helpers a bit
more cohesive--let them get the data they need.
And we have query-count coverage in our tests,
so there's no real danger of having helpers
down in the stack insidiously doing a bunch of
extra DB hops.

I added code to render_markdown that re-fetched the
sender of the message, to detect whether the message is
a bot.
It's better to just let the ORM fetch this. The
message object should already have sender.
The diff makes it look like we are saving round trips
to the database, which is true in some cases. For
the main message-send codepath, though, we are only
saving a trip to memcached, since the middleware
will have put our sender's user object into the
cache. The test_message_send test calls internally
to check_send_stream_message, so it was actually
hitting the database in render_markdown (prior to
my change).
Before this change we were clearing the cache on
every SQL usage.
The code to do this was added in February 2017
in 6db4879f9c.
Now we clear the cache just one time, but before
the action/request under test.
Tests that want to count queries with a warm
cache now specify keep_cache_warm=True. Those
tests were particularly flawed before this change.
In general, the old code both over-counted and
under-counted queries.
It under-counted SQL usage for requests that were
able to pull some data out of a warm cache before
they did any SQL. Typically this would have bypassed
the initial query to get UserProfile, so you
will see several off-by-one fixes.
The old code over-counted SQL usage to the extent
that it's a rather extreme assumption that during
an action itself, the entries that you put into
the cache will get thrown away. And that's essentially
what the prior code simulated.
Now, it's still bad if an action keeps hitting the
cache for no reason, but it's not as bad as hitting
the database. There doesn't appear to be any evidence
of us doing something silly like fetching the same
data from the cache in a loop, but there are
opportunities to prevent second or third round
trips to the cache for the same object, if we
can re-structure the code so that the same caller
doesn't have two callees get the same data.
Note that for invites, we have some cache hits
that are due to the nature of how we serialize
data to our queue processor--we generally just
serialize ids, and then re-fetch objects when
we pop them off the queue.
The passwords generated for our development environment / test suite
include the `+` character, which needs to be quoted when encoded as an
HTTP POST parameter.
This is hopefully sufficient to fix the CI failures we've seen with
the tests for POST /api/v1/fetch_api_key; I haven't reproduced the
failure so am not completely sure.
Steve asked me to remove this, since the tictactoe game was always
intended as a proof of concept. Now that we have poll and todo
widgets, the sample code for tictactoe has much less value.
We replace the content and type in test_widgets.py to maintain
coverage.
This reverts commit 564b199fe6, which
was part of #16308.
Escaping is either required or incorrect; it is never “defensive”.
This escaping is incorrect. lxml already escapes attributes during
serialization (any other behavior would be a serious bug), and
additional escaping just results in double escaping.

Initally, when writing two or more quotes, having
a blank line in between them, merges those quotes.
This created confusion especially in "quote and reply".
This commit fixes such issues. Now two or more quotes
having a blank line in between them, will not get merged.
This change is correct both for usability and for improving our
compatibility with CommonMark.
Fixes#14379.
By registering a post_delete handler to clear appropriate caches in a
nicer way, we can get rid of the ugly flush-memcached call in the
delete_realm command.
This commit adds migration which removes default status of exisitng
default private streams, i.e. private stream exists but they are no
longer default.
This commit removes mock.patch with assertLogs().
* Adds return value to do_rest_call() in outgoing_webhook.py, to
support asserting log output in test_outgoing_webhook_system.py.
* Logs are not asserted in test_realm.py because it would require to users
to be queried using users=User.objects.filter(realm=realm) and the order
of resulting queryset varies for each run.
* In test_decorators.py, replacement of mock.patch is not done because
I'm not sure if it's worth the effort to replace it as it's a return
value of a function.

Our test-backend validation confirms that we don't log anything to
stdout in the tests, so the fact that CI passes with this removes
shows there was nothing being logged.
Boto3 does not allow setting the endpoint url from
the config file. Thus we create a django setting
variable (`S3_ENDPOINT_URL`) which is passed to
service clients and resources of `boto3.Session`.
We also update the uploads-backend documentation
and remove the config environment variable as now
AWS supports the SIGv4 signature format by default.
And the region name is passed as a parameter instead
of creating a config file for just this value.
Fixes#16246.
The `no_proxy` parameter does not work to remove proxying[1]; in this
case, since all requests with this adapter are to the internal Tornado
process, explicitly pass in an empty set of proxies to disable

Not all of the workers are known to be safe to interrupt; they might
leave inconsistent state. As such, terminating them with timeouts
should currently only be a last-resort against stalled queues, not a
regular occurrence.
Since the exception can be triggered at arbitrary places in the stack
based on whenever the alarm happens to fire, they do not often group
together.
Explicitly group them together, grouped only by which queue the work
is in.
While working on shifting toward native browser time zone APIs
(#16451), it was found that all but very recent Chrome and Node
versions reject certain legacy timezone aliases like US/Pacific
(https://crbug.com/364374).
For now, we only canonicalize the timezone property returned in user
objects and not the timezone setting itself.

During the new user creation code path, there can be no existing
active clients for the user being created, so we can skip the code to
send events to that user's clients.
The tests here reflect that we need to send fewer events, and do fewer
queries that would have been spent computing data for these..
Fixes#16503, combined with the long series of recent changes by Steve
Howell to fix super-linear behavior in this code path.
We no bulk up peer_add/peer_remove events by user if the
same user has subscribed to multiple streams (and just
that single user).
This mostly optimizes the new-user codepath, but the
algorithm is a bit more general in nature.
This test was flaky due to some date-related
non-determinism. I make all the Message objects
current to make add_new_user_history reliably
try to bulk-update UserMessage rows to read.
We replace knight command with change_user_role command which
allows us to change role of a user to owner, admins, member and
guest. We can also give/revoke api_super_user permission using
this command.
Tweaked by tabbott to improve the logging output and update documentation.
Fixes#16586.
Because of the very large `oneOf` clause of the formats of events
possible in Zulip's `GET /events` system, we had issues with
`test-backend` failures for missing documentation for a new event
format being like 1000 lines of output, which was very much unhelpful.
Fix this by limiting the output use only the oneOf variants that are
broadly similar to the actual payload received.
Fixes#16023.

The comment still pointed to 'vacate' event flow, but
we have removed the vacate event in a9356508ca.
This commit fixes the comment to depict the correct
purpose of below lines, i.e. to test the remove
event flow.
We were including 'realm_user' in event_types along with 'subscription',
but we don't send event of type 'realm_user' when subscribing to a new
stream. This was added in 1c332f5d6a.
This commit removes 'realm_user' from event_types.
The name used to be included in the id_token, but this seems to have
been changed by Apple and now it's sent in the `user` request param.
https://github.com/python-social-auth/social-core/pull/483 is the
upstream PR for this - but upstream is currently unmaintained, so we
have to monkey patch.
We also alter the tests to reflect this situation. Tests no longer put
the name in the id_token, but rather in the `user` request param in the
browser flow, just like it happens in reality.
An adaptation has to be made in the native flow - since the name won't
be included by Apple in the id_token anymore, the app, when POSTing
to the /complete/apple/ endpoint,
can (and should for better user experience)
add the `user` param formatted as json of
{"email": "hamlet@zulip.com", "name": {"firstName": "Full", "lastName": "Name"}}
dict. This is also reflected by the change in the
native flow tests.
We now can send an implied matrix of user/stream tuples
for peer_add and peer_remove events.
The client code basically does this:
for stream_id in event['stream_ids']:
for user_id in event['user_ids']:
update_sub(stream_id, user_id)
We used to send individual events, which gets real
expensive when you are creating new streams. For
the case of copy-to-stream case, we should see
events go from U to 1, where U is the number of users
added.
Note that we don't yet fully optimize the potential
of this schema. For adding a new user with lots
of default streams, we still send S peer_add events.
And if you subscribe a bunch of users to a bunch of
private streams, we only go from U * S to S; we can't
optimize it down to one event easily.

All the fields of a stream's recipient object can
be inferred from the Stream, so we just make a local
object. Django will create a Message object without
checking that the child Recipient object has been
saved. If that behavior changes in some upgrade,
we should see some pretty obvious symptom, including
query counts changing.
Tweaked by tabbott to add a longer explanatory comment, and delete a
useless old comment.
This saves us a query for edge cases like when
you try to unsubscribe from a public stream
that you have already unsubscribed from.
But this is mostly to prep for upcoming
optimizations.
This doesn't change anything yet, but the goal is
to eventually optimize events for the case where
one user (typically a new user) gets subscribed
to multiple public streams.
Initially markdown titles were overridden by Youtube and Vimeo preview titles.
But now it will check if any markdown title is present to replace Youtube or

There was no need to put "stream_id" on the sub
dictionary here. It's kinda annoying to introduce
the little helper here, but I feel
that's better than crufting up the sub data
structure.
The is_web_public flag is already in Stream.API_FIELDS,
so there is no reason for all this complicated logic.
There's no reason to hack it on to the subscription
object.
We replace all_streams_id with a map.
We also use it to populate never_subscribed_streams.
And all_streams_map is a superset of stream_hash,
which we will soon kill off as well.
Apparently I put these parens in the code as
part of 73c30774cb
during 2017.
It looks like I extracted is_public during
the middle of my change and forgot to remove
the unnecessary parens. (The code was correct,
but it makes it look like a tuple if you're
skimming it too quickly.)
That class is an artifact of when Stream
didn't have recipient_id. Now it's simpler
to deal with stream subscriptions.
We also save a query during page load (and
other places where we get subscriber
info).
Let the callers access stream.recipient as needed.
It costs the same, and some of the callers can
actually stop caring about the actual Recipient
object.
We already trust ids that are put on our queue
for deferred work. For example, see the code for
"mark_stream_messages_as_read_for_everyone"
We now pass stream_recipient_id when we queue
up work for do_mark_stream_messages_as_read.
This generally saves about 3 queries per
user when we unsubscribe them from a stream.
We get two speedups:
* The query to get existing subscribers only
gets the two fields we need. We no longer
need all the overhead of user_profile
and recipient data being returned in the
query.
* We avoid Django making extra hops to the
database to get user info.
Previously, the transaction.atomic() was not properly scoped to ensure
that RealmAuditLog entries were created in the same transaction,
making it possible for state changes to not be properly recorded in
RealmAuditLog.
When apps like mobile register for "streams", we
will now just use active streams as our baseline,
rather than "occupied" streams.
This means we will send a stream that is active,
even if it happens to have zero occupants. It's
actually pretty rare that a stream has zero occupants,
and it's not exactly clear that we want to exclude
a non-occupied but otherwise active stream from
our list of streams.
It also happens to be fairly expensive to compute
whether a stream is occupied.
This change only affects API clients (including
possibly our mobile app). The main webapp never
used the data from this codepath.
We replace get_peer_user_ids_for_stream_change
with two bulk functions to get peers and/or
subscribers.
Note that we have three codepaths that care about
peers:
subscribing existing users:
we need to tell peers about new subscribers
we need to tell subscribed user about old subscribers
unsubscribing existing users:
we only need to tell peers who unsubscribed
subscribing new user:
we only need to tell peers about the new user
(right now we generate send_event
calls to tell the new user about existing
subscribers, but this is a waste
of effort that we will fix soon)
The two bulk functions are this:
bulk_get_subscriber_peer_info
bulk_get_peers
They have some overlap in the implementation,
but there are some nuanced differences that are
described in the comments.
Looking up peers/subscribers in bulk leads to some
nice optimizations.
We will save some memchached traffic if you are
subscribing to multiple public streams.
We will save a query in the remove-subscriber
case if you are only dealing with private streams.
This will ensure that we always fully execute the database part of
modifying subscription objects. In particular, this should prevent
invariant failures like #16347 where Subscription objects were created
without corresponding RealmAuditLog entries.
Fixes#16347.
We don't need the select_related('user_profile')
optimization any more, because we just keep
track of user info in our own data structures.
In this codepath we are never actually modifying
users; we just occasionally need their ids or
emails.
This can be a pretty substantive improvement if
you are adding a bunch of users to a stream
who each have a bunch of their own subscriptions.
We could also limit the number of full rows in this
query by adding an extra hop to the DB just to
get colors (using values_list), and then only get
full sub info for the streams that we're adding, rather
than getting every single subscription, in full, for each user.
Apart from finding what colors the user has already
used, the only other reason we need all the columns
in Subscription here is to handle streams that
need to be reactivated. Otherwise we could do
only("id", "active", "recipient_id", "user_profile_id")
or similar. Fortunately, Subscription isn't
an overly wide table; it's mostly bool fields.
But by far the biggest thing to avoid is bringing
in all the extra user_profile data.
We have pretty good coverage on query counts here,
so I think this fix is pretty low risk.
This class removes a lot of the annoying tuples
we were passing around.
Also, by including the user everywhere, which
is easily available to us when we make instances
of SubInfo, it sets the stage to remove
select_related('user_profile').
We used to send occupy/vacate events when
either the first person entered a stream
or the last person exited.
It appears that our two main apps have never
looked at these events. Instead, it's
generally the case that clients handle
events related to stream creation/deactivation
and subscribe/unsubscribe.
Note that we removed the apply_events code
related to these events. This doesn't affect
the webapp, because the webapp doesn't care
about the "streams" field in do_events_register.
There is a theoretical situation where a
third party client could be the victim of
a race where the "streams" data includes
a stream where the last subscriber has left.
I suspect in most of those situations it
will be harmless, or possibly even helpful
to the extent that they'll learn about
streams that are in a "quasi" state where
they're activated but not occupied.
We could try to patch apply_event to
detect when subscriptions get added
or removed. Or we could just make the
"streams" piece of do_events_register
not care about occupy/vacate semantics.
I favor the latter, since it might
actually be what users what, and it will
also simplify the code and improve
performance.
The query to get "occupied" streams has been expensive
in the past. I'm not sure how much any recent attempts
to optimize that query have mitigated the issue, but
since we clearly aren't sending this data, there is no
reason to compute it.
Using web_public_guest for anonymous users is confusing since
'guest' is actually a logged-in user compared to
web_public_guest which is not logged-in and has only
read access to messages. So, we rename it to
web_public_visitor.
This is a more thorough test of adding multiple
streams for multiple users, including streams
that users have already subscribed to.
The extra queries here are due to the fact
that we call `principal_to_user_profile` in
a loop in the view. So that's an example
of O(N) overhead. We may be able to bulk-fetch
these users eventually.
This is a pure extraction, except that I remove a
redundant check that `len(principals) > 0`. Whenever
that value is false, then `new_subscriptions` will
only have one possible entry, which is the current
user, and we skip that in the loop.
We no longer do O(N) queries to get existing streams.
This is a somewhat contrived use case--generally, we
are not trying to re-subscribe a user to several
streams. Still, we want to avoid this.
This commit also makes `test_bulk_subscribe_many`
do more work, and the change to the test helped
me discover this bug.
If a user asks to be subscribed to a stream
that they are already subscribed to, then
that stream won't be in new_stream_user_ids,
and we won't need to send an event for it.
This change makes that happen more automatically.
Let
U = number of users to subscribe
S = number of streams to subscribe
We were technically doing N^3 amount of work
when we sent certain events, or to be more
precise, U * S * S amount of work. For each
stream, we were looping through a list of tuples
of size U * S to find the users for the stream.
In practice either U or S is usually 1, so the
performance gains here are probably negligible,
especially since the constant factors here
were just slinging around Python data.
But the code is actually more readable now, so
it's a double win.
We rename needs_new_sub (which sounds like
a boolean!) to new_recipient_ids, and we
calculate it explicitly within the loop, so
that we don't need to worry as much about
subsequent passes through the loop mutating it.
This allows us to also remove recipient_ids,
which in turn lets us remove recipients_map,
albeit with a small tweak for stream_map.
I also introduce the my_subs local, which
I use to more directly populate used_colors,
as well as using it as the loop var.
I think it's important that the callers understand
that bulk_add_subscriptions assumes all streams
are being created within a single realm, so I make
it an explicit parameter.
This may be overkill--I would also be happy if we
just included the assertions from this commit.
This function now does all the work that we used
to do with notify_subscriptions_added happening
inside a loop.
There's a small fine-tuning here, where we only
get recent traffic on streams that we're actually
sending events for.
We now just pass in all_subscribers_by_stream, rather
than a callback.
We also move sub_tuples_by_user closer to the
loop where we call notify_subscriptions_added.
This preserves the alpha layer on GIF images that need to be resized
before being uploaded. Two important changes occur here:
1. The new frame is a *copy* of the original image, which preserves the
GIF info.
2. The disposal method of the original GIF is preserved. This
essentially determines what state each frame of the GIF starts from
when it is drawn; see PIL's docs:

ssh always runs its command through a shell (after naïvely joining

Since this was using repead individual get() calls previously, it
could not be monitored for having a consumer. Add it in, by marking
it of queue type "consumer" (the default), and adding Nagios lines for
it.
Also adjust missedmessage_emails to be monitored; it stopped using
LoopQueueProcessingWorker in 5cec566cb9, but was never added back
into the set of monitored consumers.
This low-level interface allows consuming from a queue with timeouts.
This can be used to either consume in batches (with an upper timeout),
or one-at-a-time. This is notably more performant than calling
`.get()` repeatedly (what json_drain_queue does under the hood), which
is "*highly discouraged* as it is *very inefficient*"[1].
Before this change:
```
$ ./manage.py queue_rate --count 10000 --batch
Purging queue...
Enqueue rate: 11158 / sec
Dequeue rate: 3075 / sec
```
After:
```
$ ./manage.py queue_rate --count 10000 --batch
Purging queue...
Enqueue rate: 11511 / sec
Dequeue rate: 19938 / sec
```
[1] https://www.rabbitmq.com/consumers.html#fetching
`loopworker_sleep_mock` is a file-level variable used to mock out the
sleep() call in LoopQueueProcessingWorker; don't reuse the variable
name for something else.
Despite its name, the `queue_size` method does not return the number
of items in the queue; it returns the number of items that the local
consumer has delivered but unprocessed. These are often, but not
always, the same.
RabbitMQ's queues maintain the queue of unacknowledged messages; when
a consumer connects, it sends to the consumer some number of messages
to handle, known as the "prefetch." This is a performance
optimization, to ensure the consumer code does not need to wait for a
network round-trip before having new data to consume.
The default prefetch is 0, which means that RabbitMQ immediately dumps
all outstanding messages to the consumer, which slowly processes and
acknowledges them. If a second consumer were to connect to the same
queue, they would receive no messages to process, as the first
consumer has already been allocated them. If the first consumer
disconnects or crashes, all prior events sent to it are then made
available for other consumers on the queue.
The consumer does not know the total size of the queue -- merely how
many messages it has been handed.
No change is made to the prefetch here; however, future changes may
wish to limit the prefetch, either for memory-saving, or to allow
multiple consumers to work the same queue.
Rename the method to make clear that it only contains information
about the local queue in the consumer, not the full RabbitMQ queue.
Also include the waiting message count, which is used by the
`consume()` iterator for similar purpose to the pending events list.
