Anders Kaseorg ac5cbf7693 Revert "markdown: Escape lang when echoing back custom non-pygments languages."
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.

akshatdalton 620e9cbf72 markdown: Fix merging of separate quotations.
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.

m-e-l-u-h-a-n cbfd6464a5 logging: replace mock.patch() for logging with assertLogs()
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.

Tweaked by tabbott to set proper mypy types.

Tim Abbott 6d7cd351a3 events: Optimize creating streams for new users.
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..

Mateusz Mandera 48f80fcb0a auth: Expect name in request params in Apple auth.
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.

Steve Howell 7ff3859136 subscriber events: Change schema for peer_add/peer_remove.
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.

Steve Howell 85ed6f332a performance: Avoid Recipient lookup for stream messages.
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.

Steve Howell 0b91526f28 events: Remove "occupied" semantics for "streams".
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.
2020-10-15 15:12:01 -07:00
Steve Howell b4346d0276 performance: Extract subscribers/peers in bulk.
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.

without corresponding RealmAuditLog entries.

Fixes #16347.
2020-10-14 11:06:00 -07:00
Steve Howell 5728149e94 performance: Streamline query to add subscribers.
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.
2020-10-14 11:03:07 -07:00
Steve Howell 116a441bc5 refactor: Introduce SubInfo class.
This class removes a lot of the annoying tuples

Also, by including the user everywhere, which

select_related('user_profile').

Steve Howell a9356508ca events: Stop sending occupy/vacate events.
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.
2020-10-14 10:53:10 -07:00
Steve Howell 1bcb8d8ee8 performance: Avoid computing page_params.streams in webapp.
The query to get "occupied" streams has been expensive
in the past.  I'm not sure how much any recent attempts

since we clearly aren't sending this data, there is no
reason to compute it.

read access to messages. So, we rename it to
web_public_visitor.

Steve Howell e7a8c7ac48 test: Improve tests for bulk-adding subscribers.
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.

Steve Howell c29ba75135 refactor: Extract send_messages_for_new_subscribers.
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.

Steve Howell 3b338ec32e performance: Optimize filter_stream_authorization.
We no longer do O(N) queries to get existing streams.

This is a somewhat contrived use case--generally, we

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.

This change makes that happen more automatically.

Steve Howell 18771099e4 performance: Introduce new_stream_user_ids.
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

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.

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
```

Alex Vandiver d5a6b0f99a queue: Rename queue_size, and update for all local queues.
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.

Alex Vandiver d47637fa40 queue: Set a max consume timeout with SIGALRM.
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.

Alex Vandiver baf882a133 queue: Only ACK drain_queue once it has completed work on the list.
Currently, drain_queue and json_drain_queue ack every message as it is
pulled off of the queue, until the queue is empty.  This means that if
the consumer crashes between pulling a batch of messages off the
queue, and actually processing them, those messages will be
permanently lost.  Sending an ACK on every message also results in a
significant amount lot of traffic to rabbitmq, with notable
performance implications.

Send a singular ACK after the processing has completed, by making
`drain_queue` into a contextmanager.  Additionally, use the `multiple`
flag to ACK all of the messages at once -- or explicitly NACK the
messages if processing failed.  Sending a NACK will re-queue them at
the front of the queue.

Anders Kaseorg fb2d7c6741 openapi: Fix allOf usage to conform to the OpenAPI specification.
yamole preprocesses our schema by naïvely merging all the objects in
an allOf array together, but this fails to capture the meaning of
allOf according to the OpenAPI specification.  allOf is supposed to be
a strict logical intersection of each subschema interpreted
independently.  It does not combine their properties maps before
interpreting additionalProperties.  So according to the old definition
of JsonSuccess, every response is invalid:

allOf:
  - additionalProperties: false
    properties:
      result:
        type: string
  - required:
      - result
      - msg
    properties:
      msg:
        type: string

because the first subschema disallowed msg and the second subschema
required msg.

To fix this, whenever we use allOf for schema “inheritence”, the base
schema must not specify additionalProperties, and the child schema
must explicitly list all properties recursively inherited from the
base schema in any subschema that uses additionalProperties.

Fixes #16109.

It happens that whether you add a reaction or remove

This sort of symmetry is actually kind of rare, as
usually "add" events have more fields, and "remove" events
might just send an id of something to remove.

Our openapi schema treats these as two seperate events,
so we are more consistent with it, and it helps our
schema-checking tooling for node fixtures, too.

Note that we now have to exempt the two events from
our openapi checks, due to the is_mirror_dummy field
in the deprecated user block.  We can decide how to
handle this later--one possibility is to just add it
as an optional field on the event_schema side.

Note that we make the schema for profile_data

profile data for our test realm.

We also don't have the optional fields for bots,
since our tests don't exercise that, nor
delivery_email.

So we exempt realm_user_add_event from openapi
checks for now.

When we try to match the openapi specs better, we
will probably want to add a few tests to test_events.

Obviously getting good coverage for adding users
would be nice for all these scenarios:

    * delivery_email matters
    * bots

Steve Howell 6c74a44697 data_types: Generalize StringDictType.
This is a prep commit for supporting "presence"
events, where the key of the dictionary is some
arbitrary string like "website" but the value
of the dictionary is another dictionary itself
with keys that are more like variable names.
2020-09-25 11:43:19 -07:00
Steve Howell 4f3d5f2d87 event_schema: Extract check_realm_filters.
We have some known issues with representing
tuples in openapi, so we exempt realm_filters
from the relevant check.
2020-09-25 11:43:19 -07:00
Steve Howell e40a5400e5 event_schema: Extract check_muted_topics.
This also forces us to create TupleType.

We exempt this from the openapi check,
since we haven't figured out how to model
tuples in openapi with the same precision
as event_schema (and it may be impossible).

Long term we just want to stop dealing in
tuples, of course.

orientor 91ca1afe98 data_type: Add StringDict data type.
StringDict is a data type for representing dictionaries where
all keys and values are strings. Add this data type to data_types.py
and edit other files so that this data type is put to use and tested.

(slightly tweaked by @showell to remove a comment and shorten
a var name now that we have a proper data type)

Steve Howell cf26151cea event_schema: Use realm_user_person_types.
For realm_user events, we now structure the
person type as a union of dicts, which is
more consistent with how we model this in
our openapi spec.
2020-09-25 11:43:19 -07:00
Steve Howell 10952394b0 test_events: Use int value of message_retention_days.
We also make our schema in event_schema reflect this,
which in turn makes us match the already accurate
openapi spec, so we no longer need to exempt four
types of events from our sanity checks.

Steve Howell 73e7f7edec check-node-fixtures: Compare python/openapi schemas.
We might want to rename the tool to something more
general now, since we are really reconciling three
things:

    - node fixtures
    - event_schema checkers for test_events
    - openapi specs

The way we compare python and openapi schemas is
as follows:

    - first convert openapi schemas to be build
      from DictType, ListType, etc. with from_opeapi

    - do a diff on the schemas

Most of the new code is just having the FooType
family of classes serialize themselves with schema().

Steve Howell aca641a4d1 refactor: Extract data_types module.
Defining types with an object hierarchy
of type classes will allow us to build
functionality that was impossible (or
really janky) with the validators.py
approach of composing functions.

Most of the changes to event_schema.py
were automated search/replaces.

This patch doesn't really yet take
advantage of the new FooType classes,
but we will use it soon to audit our
openapi specs.

Steve Howell e0b6619dac bitbucket2: Simplify how we display user for fork events.
Even before GDPR changes, it was strange that we displayed
users differently for fork events vs. all other events.

After GDPR, we don't even get the `username` field any
more.

So now we simply use `display_name` if available, and then
we try `nickname`.

Steve Howell 1ef8d79352 bitbucket: Decouple BITBUCKET_FORK_BODY between versions.
We were trying to share the same format string between
the two different versions of bitbucket, but this only
creates confusion, as the two versions are only close
enough to be confusing.

The format string might be the same, but the semantics
are different, as well as the eventual outputs.

For example, the {username} piece here is simple in version
2, but in version 3 we append a url to the user's name.

Aman Agrawal 3ec23e1a9d fetch_initial_state_data: Handle case of web public guests.
user_profile will be None for web_public_guests here.  Hence, for
settings (of which most be inaccessible by web public guest),
which require a user_profile, we either set an empty value for
them or set them to a default value. This will help render
the frontend or extend support to our clients without breaking
a lot of code.

Tweaked by tabbott to add many comments.

Alex Vandiver 1a763696f7 webhooks: Only enable webhook logging if it is a webhook.
allow_webhook_access may be true if the request allows webhook
requests, regardless of if it only used for a webhook integration.

Only actually log to the verbose webhook logger if it is explicitly a
webhook endpoint, as judged by `webhook_client_name`.  This prevents
requests for `POST /api/v1/messages` from being logged to the webhook
logger if they mistakenly contain a `payload` argument.
2020-09-22 15:11:48 -07:00
Alex Vandiver 77d1a4a5c0 webhooks: Simplify logic around is_webhook_access.
We clearly allow webhook access if we are setting the

Alex Vandiver d24869e484 webhooks: Rename is_webhook to allow_webhook_access.
This argument does not define if an endpoint "is a webhook"; it is set

access from webhooks.

Having both of these is confusing; TORNADO_SERVER is used only when

TORNADO_PORTS.

In development and test, we keep the Tornado port at 9993 and 9983,

In production, moving to port 9800 consistently removes an odd edge

Alex Vandiver 5a9b6feb18 tornado: Retry POST requests from Django to Tornado.
While urllib3 retries all connection errors, it only retries a subset
of read errors, since not all requests are safe to retry if they are
not idempotent, and the far side may have already processed them once.
By default, the only methods that are urllib3 retries read errors on
are GET, TRACE, DELETE, OPTIONS, HEAD, and PUT.  However, all of the
requests into Tornado from Django are POST requests, which limits the
effectiveness of bb754e0902.

POST requests to `/api/v1/events/internal` are safe to retry; at worst,
they will result in another event queue, which is low cost and will be
GC'd in short order.

POST requests to `/notify_tornado` are _not_ safe to retry, but this
codepath is only used if USING_RABBITMQ is False, which only occurs
during testing.

Enable retries for read errors during all POSTs to Tornado, to better
handle Tornado restarts without 500's.

Alex Vandiver ff94254598 tornado: Log to files by port number.
Without an explicit port number, the `stdout_logfile` values for each
port are identical.  Supervisor apparently decides that it will
de-conflict this by appending an arbitrary number to the end:

```
/var/log/zulip/tornado.log
/var/log/zulip/tornado.log.1
/var/log/zulip/tornado.log.10
/var/log/zulip/tornado.log.2
/var/log/zulip/tornado.log.3
/var/log/zulip/tornado.log.7
/var/log/zulip/tornado.log.8
/var/log/zulip/tornado.log.9
```

This is quite confusing, since most other files in `/var/log/zulip/`
use `.1` to mean logrotate was used.  Also note that these are not all
sequential -- 4, 5, and 6 are mysteriously missing, though they were
used in previous restarts.  This can make it extremely hard to debug
logs from a particular Tornado shard.

Give the logfiles a consistent name, and set them up to logrotate.

Alex Vandiver 812af977d3 compilemessages: Switch to canonical override_language(). 2020-09-14 22:16:09 -07:00
Alex Vandiver 536bd3188e middleware: Move locale-setting before domain checking.
Calling `render()` in a middleware before LocaleMiddleware has run
will pick up the most-recently-set locale.  This may be from the
_previous_ request, since the current language is thread-local.  This
results in the "Organization does not exist" page occasionally being
in not-English, depending on the preferences of the request which that
thread just finished serving.

Move HostDomainMiddleware below LocaleMiddleware; none of the earlier
middlewares call `render()`, so are safe.  This will also allow the
"Organization does not exist" page to be localized based on the user's
browser preferences.

Unfortunately, it also means that the default LocaleMiddleware catches
the 404 from the HostDomainMiddlware and helpfully tries to check if
the failure is because the URL lacks a language component (e.g.
`/en/`) by turning it into a 304 to that new URL.  We must subclass
the default LocaleMiddleware to remove this unwanted functionality.

Doing so exposes a two places in tests that relied (directly or
indirectly) upon the redirection: '/confirmation_key'
was redirected to '/en/confirmation_key', since the non-i18n version
did not exist; and requests to `/stats/realm/not_existing_realm/`
incorrectly were expecting a 302, not a 404.

This regression likely came in during f00ff1ef62, since prior to
that, the HostDomainMiddleware ran _after_ the rest of the request had
completed.

sahil839 9c3341ad95 openapi: Rearrange users/{user_id}/subscriptions/{stream_id} docs.
This commit moves docs for users/{user_id}/subscriptions/{stream_id}
enndpoint to be after users/me/subscriptions/muted_topics docs.

We are rearranging the docs because after adding the new patch
endpoint for users/{user_id}/subscriptions/{stream_id}, openapi_core
validator tries to match 'users/me/subscriptions/muted_topics'
with 'users/{user_id}/subscriptions/{stream_id}' path in zulip.yaml
and thus gives error while running tests.

This is a bug in 'openapi_core' as it does not follows OpenAPI specs
to match concrete paths before their templated counterparts. Thus,
this commit rearranges the docs such that openapi_core validator
tries to match muted_topics endpoint with the correct path in
zulip.yaml docs.

Sumanth V Rao 033351609d markdown: Add data-codehilite-language attr for fenced code.
When converting fenced code markdown, we add the language (if specified)
in a data-attribute by tweaking the HTML generated. Doing so, allows the
frontend to make use of this attr to display view-in-playground option
for codeblocks.

We use pygments to get the lexer subclass name and use that instead of
directly using the language in the data-attribute. Doing so, helps us
map different language aliases (like `js` and `javascript`) into a common
variable (like `JavaScript`) - and avoids the client from dealing with
multiple tags corresponding to the same language.

The html structure for a message like this:

``` js
..content..
```

would now be:

<div class="codehilite" data-codehilite-language="JavaScript">
    <pre>..content..</pre>
</div>

Tests and fixtures amended.
