Alex Vandiver 012113c542 models: Force the translated role into a translated string.
The return type of `ugettext_lazy('...')` (aliased as `_`) is a
promise, which is only forced into a string when it is dealt with in
string context.  This `django.utils.functional.lazy.__proxy__` object
is not entirely transparent, however -- it cannot be serialized by
`orjson`, and `isinstance(x, str) == False`, which can lead to
surprising action-at-a-distance.

In the two places which will serialize the role value (either into
Zulip's own error reporting queue, or Sentry's), force the return
value.  Failure to do this results in errors being dropped
mostly-silently, as they cannot be serialized and enqueued by the
error reporter logger, which has no recourse but to just log a
warning; see previous commit.

When we do this forcing, explicitly override the language to be the
realm default.  Failure to provide this override would translate the
role into the role in the language of the _request_, yielding varying
results.

Alex Vandiver 2f350c614b sentry: Capture exceptions that happen during AdminNotifyHandler.
AdminNotifyHandler is used to notify admins of errors; it is a
critical piece of logic.  Failures in reporting errors will compound,
since its `except Exception` clauses cannot generate logging at the
`error` or `exception` level, as that would be recursive.  It must
settle for logging at the `warning` level, and hope that admins are
vigilant to the logging there.

Increase the chances of being notified of failures in this logger, by
bubbling up those exceptions to Sentry, which is an orthogonal
reporting stack.

Steve Howell 5bff66b450 github webhook: Always send messages for team edits.
If there are unsupported keys, we still log an error,
but we now also send a message to the stream.  (This
is a good tradeoff for the github webhook, since users
can just turn off notifications if they find it spammy.
Also, we intend to support "repository" soon.)

This is a bit of an experiment to see how this plays
in the field:

    * will customers notice the change?
    * will Sentry reports look any different?

Steve Howell c6b9a23c17 github webhooks: Fix message for unsupported team payloads.
The main thing fixed here is that we weren't turning

a bit more, including sorting the keys.

I also avoid the unnecessary "else".

Steve Howell cc2dbefc60 mypy: Use better types for EVENT_FUNCTION_MAPPER.
The EVENT_FUNCTION_MAPPER maps a string event name
to a function handler.  Before this we circumvented
mypy checks with a call to get_body_function_based_on_type,
which specified Any as the type of our event function.

Now the types are rigorous.

This change was impossible without the recent commit
to introduce the Helper class.
2020-09-03 10:44:39 -07:00
Steve Howell 4de2b78c25 github refactor: Add Helper class.
The Helper class will soon grow, but the immediate
problem it solves is the need to jankily inspect
the parameters of our get_*_body function.

Most of the changes were handled by an ad hoc
munge.py script.

The substantive changes were adding the Helper
class and passing it in.

And then the linter discovered a place where
the optional include_title parameter wasn't used
(which is one of the reasons to avoid the janky
inspect-signature technique).

As a side note, none of the include_title parameters
needed a default value of False, as we always passed
in an explicit value.

We test cover both sides of include_title, which
you can verify by hard coding it to either True or
False (and seeing the relevant failures), although I
suspect most individual codepaths
only test one value, based on whether "topic" is in
the fixture or not.

Finally, I know Helper is not a great name, but I
intend to evolve the class a bit before deciding
whether a more descriptive name is helpful here.
(For example, an upcoming commit will add a
log_unexpected helper method.)

Steve Howell ead7cbea40 github refactor: Handle header_event explicitly.
We get the header_event one level up the call
stack now, too.

It's somewhat annoying that we have our own
concept of "event" here, instead of just returning
our event handlers directly, or just calling them
directly, but it's a bit non-trivial to fix that
right away.

In passing, I remove the strange OR for "ping",
which is already a key in EVENT_FUNCTION_MAPPER.

Steve Howell 294fd59983 github webhook: Ignore more pull_request actions.
See https://github.com/zulip/zulip/issues/16258 for
possible follow up here.

We now ignore the following two new pull_request
actions (as well as the three existing ones
from before):

    approved
    converted_to_draft

As the issue above indicates, we may want to actually
support "approved" if we can find somebody to work
on the webhook.  (And then the issue goes a little
broader than what changed here.)

Steve Howell 5dea85a186 github tests: Extract test_ignored_pull_request_actions.

Steve Howell e91e21c9e7 webhook logger: Add summary field.
Before this the only way we took advantage
of the summary from UnexpectedWebhookEventType
was by looking at exc_info().

Now we just explicitly add it to the log
message, which also sets us up to call
log_exception_to_webhook_logger directly
with some sort of "summary" info
when we don't actually want a real
exception (for example, we might want to
report anomalous webhook data but still
continue the transaction).

A minor change in passing is that I move
the payload parameter lexically.

was no longer being used.

Mateusz Mandera 74d3e83e24 tests: Use real path when getting commands in TestCommandsCanStart.
In 468c5b9a58 we changed the method of
getting the list of management commands. Using app_config.path has a
caveat in that the value depends on the path from which we're executing.
An example of things breaking can be reproduced by calling
/home/vagrant/zulip/tools/test-backend TestCommandsCanStart

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.

Alex Vandiver 398102e215 sentry: When there are multiple stacktraces, take the most recent.
Sentry may get reported multiple exceptions stacks, in the case where
a `raise ...` was caught, and a new exception was `raise`d.  In this
case, the `filename` is the most recent exception -- but the
exceptions are stored in the `exception` key in the order in which
they occurred.  As such, taking the first value with a `stacktrace`
will result in showing the wrong line, or in no stack trace being
resolved at all.

Look from the last `exception` backwards, for matching stacks.

Kartik Srivastava b9b9a79382 user_groups: Use 'path_only=True' in REQ for 'user_group_id' in views.
'user_groups' endpoints are currently under 'pending_endpoints' in
test_openapi.py (even after being documented except one), due to the
'user_group_id' and 'group_id' parameter name mismatch in the
url config and the view functions.

This commit includes 'path_only=True' for 'user_group_id' parameter in
views to avoid the failure of 'test_openapi_arguments', in
test_openapi.py, which excludes the path parameters. This is a prep
commit for renaming 'group_id' to 'user_group_id' in the documentation
and removing the 'user_groups' endpoints from 'pending_endpoints'.

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.

Aman c355f6b8d8 exceptions: Extract json_unauths into MissingAuthenticationError.
We raise two types of json_unauthorized when
MissingAuthenticationError is raised. Raising the one
with www_authenticate let's the client know that user needs
to be logged in to access the requested content.

Sending `www_authenticate='session'` header with the response
also stops modern web-browsers from showing a login form to the
user and let's the client handle it completely.

Structurally, this moves the handling of common authentication errors
to a single shared middleware exception handler.

Hemanth V. Alluri 31a5e0b441 openapi: Fix DELETE /users/me status 200 response description.
If you look at line number 1121 (new) of commit 14c0a387cf,
I seem to have accidently set the description for a status
200 response to "Bad Request" instead of "Success" which
is what it really is. It's basically an ugly typo (maybe
due to hastily copy-pasting the template).

I can find no evidence of it being possible to get an Exception when

Steve Howell 95fe690e8d webhook tests: Avoid lots of unnecessary json dumping.
Commit c4254497b2
curiously had get_body() round tripping its data
through json load and dump.

I have seen this done for pretty-printing reasons,
but it doesn't apply here.

And if you're doing it for validation reasons,
you only need to do half the work, as my commit
here demonstrates.

We arguably don't even need the fail-fast code
here, since our fixtures are linted to be proper
json, I believe, plus downstream code probably
gives reasonably easy-to-diagnose symptoms.

Steve Howell 6d65af1790 webhook tests: Remove needless get_body functions.

2020-08-24 12:34:46 -07:00
Steve Howell 7fbe08f515 webhook tests: Introduce get_payload.
We introduce get_payload for the relatively
exceptional cases where webhooks return payloads
as dicts.

Having a simple "str" type for get_body will
allow us to extract test helpers that use
payloads from get_body() without the ugly
`Union[str, Dict[str, str]]` annotations.

I also tightened up annotations in a few places
where we now call get_payload (using Dict[str, str]
instead of Dict[str, Any]).

In the zendesk test I explicitly stringify
one of the parameters to satisfy mypy.

Steve Howell f7e4cc28eb mypy: Use str for get_body in bitbucket.

Steve Howell 025d1fa180 webhook tests: Require args for check_webhook.
We tighten up the mypy types here.  And then
once we know that expected_message and expected_topic
are never None, we don't have call the do_test_message
and do_test_topic helpers any more, so we eliminate
them, too.

Finally, we don't return a message, since no tests
use the message currently.
2020-08-24 12:34:46 -07:00
Steve Howell fae3535e79 webhook tests: Avoid check_webhook for multi messages.
If we're not passing in expected_topic or expected_message
to check_webhook, it's better to just call send_webhook_payload,
since we'll want to explicitly check our messages
anyway.

This preps us to always require those fields for
check_webhook, which can prevent insidious testing no-ops.
2020-08-24 12:34:46 -07:00
Steve Howell f74aa29a1c webhook tests: Extract assert_stream_message.
This forces us to be a bit more explicit about testing
the three key values in any stream message, and it
also de-clutters the code a bit.  I eventually want
to phase out do_test_topic and friends, since they
have the pitfall that you can call them and have them
do nothing, because they don't actually require
values to be be passed in.

I also clean up the code a bit for the tests that
have two new messages arriving.
2020-08-24 12:34:46 -07:00
Steve Howell 3a710ab996 webhook tests: Remove stream_name parameter.
Having an optional stream_name parameter makes
it confusing to read the code if you know your
webhook is sending private messages.

And then the other two callers are already
checking topics, so they might as well check
stream names, too.

We also have the two stream-oriented callers
make their own call to "subscribe".  And we
future-proof this by making sure the exception
for no-message-being-sent calls out that gotcha.

Somewhat in passing, we now assert that
self.STREAM_NAME is not None in the main
helper.  This is partly to satisfy mypy, but
it's also a good sanity check.

This also sets the stage for the next commit,
where I'll add an assert_stream_message helper.
2020-08-24 12:34:46 -07:00
Steve Howell 2fdf966d9f webhook tests: Rename helper to send_webhook_payload.
Not all webhook payloads are json, so send_json_payload was a
bit misleading.

In passing I also remove "bytes" from the Union type for
"payload" parameter.
2020-08-24 12:34:46 -07:00
Steve Howell 388053db6b webhook tests: Rename main helper to check_webhook.
Almost all webhook tests use this helper, except a few
webhooks that write to private streams.

Being concise is important here, and the name
`self.send_and_test_stream_message` always confused
me, since it sounds you're sending a stream message,
and it leaves out the webhook piece.

We should consider renaming `send_and_test_private_message`
to something like `check_webhook_private`, but I couldn't
decide on a great name, and it's very rarely used.  So
for now I just made sure the docstrings of the two
sibling functions reference each other.

Steve Howell 00001a396b webhook tests: Shorten topic constants.
The "EXPECTED_" prefix and "_EVENTS" suffix

We also use module constants to avoid the "self."
noise.  It also makes it a bit more clear which
constants actually have to be in the class (e.g.
"FIXTURE_DIR_NAME") to do their job.
2020-08-24 12:34:46 -07:00
Steve Howell 0f970c6971 minor: Avoid do_test_message.
This function is a bad idea, as it leads to a possible situation
where you aren't actually testing anything:

    def do_test_message(self, msg: Message, expected_message: Optional[str]) -> None:
        if expected_message is not None:
            self.assertEqual(msg.content, expected_message)

Unfortunately, it's called deep in the stack in some places, but
we can safely replace it with assertEqual here.

Steve Howell fbef6e3c03 zendesk tests: Fix anti-patterns.
We had optional parameters for expected_topic and
expected_message, which are trivial to eliminate,
since the integration is really simple.

And we were doing strange things trying to reset
class variables at the end of tests.  Now we just
set them explicitly in the tests.
2020-08-24 12:34:46 -07:00
Steve Howell 3de2e4f034 dialogflow test: Fix nonsensical tests.
The test helper here was taking an "expected_topic"
parameter that it just ignored, and then the
dialogflow tests were passing in expected messages
in that slot, so the actual "expected_message" var
was "None" and was ignored.  So the tests weren't
testing anything.

Now we eliminate the crufty expected_topic parameter
and require an actual value for "expected_message".

I also clean up the mypy type for content_type,
and I remove the `content_type is None` check,
since all callers either pass in a str content
type or default to "application/json".

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.
