akshatdalton 287c4ed2bb markdown: Fix Youtube and Vimeo preview overriding markdown link titles bug.
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
Vimeo preview titles, if preview of linked websites is enabled.
Fixes #16100

Anders Kaseorg d81a93cdf3 requirements: Upgrade markdown to 3.3.1.
Upstream has slightly changed the whitespace around stashes.  Take
this opportunity to clean up the extra blank lines we were outputting.

Steve Howell 4dce34ab8b refactor: Simplify call to bulk_get_subscriber_user_ids.
The way we were computing the dictionary was very
convoluted--all we need is a set of subscribed user
ids.

Steve Howell 0ca07ffd3c peformance: Eliminate StreamRecipientMap.
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).

Steve Howell 378062cc83 performance: Avoid call to access_stream_by_id.
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.

Steve Howell 6d1f9de7d3 performance: Use SubInfo when removing subscribers.
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.

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.

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.

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
to optimize that query have mitigated the issue, but
since we clearly aren't sending this data, there is no
reason to compute it.

Aman Agrawal fbf7cb82a7 web_public_guest: Rename to web_public_visitor for clarity.
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.

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.
2020-10-13 18:54:55 -04:00
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.
2020-10-13 18:54:55 -04:00
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
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.

Steve Howell 598601e8fc stream events: Prevent spurious events.

that they are already subscribed to, then
that stream won't be in new_stream_user_ids,

I think it's important that the callers understand

This may be overkill--I would also be happy if we
just included the assertions from this commit.

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

Alex Vandiver f9358d5330 queue: Switch batch interface to use the channel.consume iterator.
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
```

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.

message_send: Fix old guests being treated as full members.
For streams in which only full members are allowed to post,
we block guest users from posting there.

Guests users were blocked from posting to admin only streams
already. So now, guest users can only post to
STREAM_POST_POLICY_EVERYONE streams.

This is not a new feature but a bugfix which should have
happened when implementing full member stream policy / guest users.

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.

A later commit alters `authenticate` of EmailAuthBackend to

runs `authenticate` without a `request` object. So, this commit

Steve Howell f6e0171d02 event_schema: Split check_reaction into add/remove.
It happens that whether you add a reaction or remove
a reaction, we send the exact same fields, just using
a different op code.

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.

Steve Howell 4084f0b949 event_schema: Extract check_realm_user_add.
Note that we make the schema for profile_data
slightly more realistic, but it doesn't actually get
exercised by our current tests (apart from
making sure it's a dict), since we don't have
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
    * realm has profile fields

tuples, of course.

Steve Howell 73e7f7edec check-node-fixtures: Compare python/openapi schemas.
We might want to rename the tool to something more

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().

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.

Aman Agrawal 2bc3924672 move_topic_to_stream: Allow moving to/between/from private streams.
Fixes #16284.

Most of the work for this was done when we implemented correct
behavior for guest users, since they treat public streams like private
streams anyway.

The general method involves moving the messages to the new stream with
special care of UserMessage.

We delete UserMessages for subs who are losing access to the message.
For private streams with protected history, we also create UserMessage
elements for users who are not present in the old stream, since that's
important for those users to access the moved messages.

Anders Kaseorg ddf8ec33df upload: Strip leading slash from deleted S3 export paths.
Previously, S3UploadBackend.delete_export_tarball failed to strip the
leading ‘/’ from the export path.  This mistake is now caught by Moto
1.3.15.  I expect it caused deletion failures in the real S3, although
I haven’t verified this.

We store export_path in the audit log with a leading ‘/’, but the
actual S3 keys do not have a leading ‘/’.  Changing either system
would require a migration.  So the new convention is that the
variables named ‘export_path’ have a leading ‘/’, while variables
named ‘path_id’ or ‘key’ do not.

Anders Kaseorg 463929f349 urls: Migrate re_path routes to path.
Django treats path("<name>") like re_path(r"(?P<name>[^/]+)") and
path("<path:name>") like re_path(r"(?P<name>.+)").

This is more readable and consistent than the mix of slightly
different regexes we had before, and fixes various bugs:

• The r'apps/(.*)$' regex was missing a start anchor ^, so it
  incorrectly matched all URLs that included apps/ as a substring
  anywhere.
• The r'accounts/login/(google)/$' regex was missing a start anchor ^,
  so it incorrectly matched all URLs that ended with
  accounts/login/google/.
• The type annotation of zerver.views.realm_export.delete_realm_export
  takes export_id as an int, but it was previously passed as a string.
• The type annotation of zerver.views.users.avatar takes medium as a
  bool, but it was previously passed as a string.
• The [0-9A-Za-z]+ pattern for uidb64 was missing the - and _
  characters that can validly be part of a base64url encoded
  string (although I think the id is actually a decimal integer here,
  in which case only 012345ADEIMNOQTUYcgjkwxyz are present in its
  base64url encoding).

Any exception is an "unexpected event", which means talking about

this is about an _unsupported_ event type.

Mateusz Mandera f95dd628bd email: Fix race conditions with concurrent ScheduledEmail handling.
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.

Anders Kaseorg b7b7475672 python: Use standard secrets module to generate random tokens.
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.)

In 468c5b9a58 we changed the method of

This makes the app_config.path values to start with /home/vagrant/zulip,
but DEPLOY_ROOT in the dev environment is set to /srv/zulip.
/home/vagrant/zulip is a soft link to /srv/zulip, so it's a valid path
to call test-backend through, but it causes self.commands to end up
being an empty list. We fix this by converting app_config.path to the
real path.

Tim Abbott 4f0f734810 urls: Simplify URL patterns for presence.
Extracting a section for presence endpoints and using path() rather
than re_path() results in a much cleaner implementation of this
concept.

This eliminates the last case where test_openapi couldn't correctly
match an endpoint documentation with the OpenAPI definitions for it.

queue: Use locking to avoid race conditions in missedmessage_emails.
This queue had a race condition with creation of another Timer while
maybe_send_batched_emails is still doing its work, which may cause
two or more threads to be running maybe_send_batched_emails
at the same time, mutating the shared data simultaneously.

Another less likely potential race condition was that
maybe_send_batched_emails after sending out its email, can call
ensure_timer(). If the consume function is run simultaneously
in the main thread, it will call ensure_timer() too, which,
given unfortunate timings, might lead to both calls setting a new Timer.

We add locking to the queue to avoid such race conditions.

Tested manually, by print debugging with the following setup:
1. Making handle_missedmessage_emails sleep 2 seconds for each email,
   and changed BATCH_DURATION to 1s to make the queue start working
   right after launching.
2. Putting a bunch of events in the queue.
3. ./manage.py process_queue --queue_name missedmessage_emails
4. Once maybe_send_batched_emails is called and while it's processing
the events, I pushed more events to the queue. That triggers the
consume() function and ensure_timer().

Before implementing the locking mechanism, this causes two threads
to run maybe_send_batched_emails at the same time, mutating each other's
shared data, causing a traceback such as

Exception in thread Thread-3:
Traceback (most recent call last):
  File "/usr/lib/python3.6/threading.py", line 916, in _bootstrap_inner
    self.run()
  File "/usr/lib/python3.6/threading.py", line 1182, in run
    self.function(*self.args, **self.kwargs)
  File "/srv/zulip/zerver/worker/queue_processors.py", line 507, in maybe_send_batched_emails
    del self.events_by_recipient[user_profile_id]
KeyError: '5'

With the locking mechanism, things get handled as expected, and
ensure_timer() exits if it can't obtain the lock due to
maybe_send_batched_emails still working.

I noticed RateLimitTests.test_hit_ratelimits fails when run as an

Alex Vandiver ad8943a64a url_preview: Only extract img tags with an `src`.
Some `<img>` tags do not have an SRC, if they are rewritten using JS
to have one later.  Attempting to access `first_image['src']` on these
will raise an exception, as they have no such attribute.

Only look for images which have a defined `src` attribute on them.  We
could instead check if `first_image.has_attr('src')`, but this seems
only likely to produce fewer valid images.

This commit adds the is_web_public field in the AbstractAttachment

* Deactivating the stream

The access_stream_for_delete_or_update is modified and is used only

rights is done by check_stream_access_for_delete_or_update.

We have also added a new exception class StreamAdministratorRequired.

Aman Agrawal 9f9daeea5b message_fetch: Allow access to web-public msgs for unauth users.
Via API, users can now access messages which are in web-public
streams without any authentication.

If the user is not authenticated, we assume it is a web-public
query and add `streams:web-public` narrow if not already present
to the narrow. web-public streams are also directly accessible.

Any malformed narrow which is not allowed in a web-public query
results in a 400 or 401. See test_message_fetch for the allowed
queries.

Alex Vandiver f00ff1ef62 middleware: Make HostDomain into a process_request, not process_response.
It is more suited for `process_request`, since it should stop
execution of the request if the domain is invalid.  This code was
likely added as a process_response (in ea39fb2556) because there was
already a process_response at the time (added 7e786d5426, and no
longer necessary since dce6b4a40f).

It quiets an unnecessary warning when logging in at a non-existent
realm.

This stops performing unnecessary work when we are going to throw it
away and return a 404.  The edge case to this is if the request
_creates_ a realm, and is made using the URL of the new realm; this
change would prevent the request before it occurs. While this does
arise in tests, the tests do not reflect reality -- real requests to
/accounts/register/ are made via POST to the same (default) realm,
redirected there from `confirm-preregistrationuser`.  The tests are
adjusted to reflect real behavior.

Tweaked by tabbott to add a block comment in HostDomainMiddleware.

Alex Vandiver 2928bbc8bd logging: Report stack_info on logging.exception calls.
The exception trace only goes from where the exception was thrown up
to where the `logging.exception` call is; any context as to where
_that_ was called from is lost, unless `stack_info` is passed as well.
Having the stack is particularly useful for Sentry exceptions, which
gain the full stack trace.

Add `stack_info=True` on all `logging.exception` calls with a
non-trivial stack; we omit `wsgi.py`.  Adjusts tests to match.

Tim Abbott e12225ace7 realm_audit_log: Fix malformed RealmAuditLog entries.
In f8bcf39014, we fixed buggy
marshalling of Streams and similar data structures where we were
including the Stream object rather than its ID in dictionaries passed
to ujson, and ujson happily wrote that large object dump into the
RealmAuditLog.extra_data field.

This commit includes a migration to fix those corrupted RealmAuditLog
entries, and because the migration loop is the same, also fixes the
format of similar RealmAuditLog entries to be in a more natural format
that doesn't weirdly nest and duplicate the "property" field.

Fixes #16066.
