A bug in the implementation of replies to messages sent by outgoing
webhooks to private streams meant that an outgoing webhook bot could be
used to send messages to private streams that the user was not intended
to be able to send messages to.
Completely skipping stream access check in check_message whenever the
sender is an outgoing webhook bot is insecure, as it might allow someone
with access to the bot's API key to send arbitrary messages to all
streams in the organization. The check is only meant to be bypassed in
send_response_message, where the stream message is only being sent
because someone mentioned the bot in that stream (and thus the bot
posting there is the desired outcome). We get much better control over
what's going by passing an explicit argument to check_message when
skipping the access check is desirable.
The `widget_content` key is expected to contain a string which parses
as JSON; in the event that it does not, log the error and notify the
bot owner, instead of failing silently.
Fixes#16850.
The session object provides a common place to set headers on all
requests, no matter which implementation.
Because the `headers` attribute of Session is not a true static
attribute, but rather exposed via overriding `__getstate__`, `mock`'s
autospec cannot know about it, and thus throws an error; in tests that
mock the Session, we thus must explicitly set the `session.headers`.
The existing organization, of returning an opaque blob from
`build_bot_request`, which was later consumed by
`send_data_to_server`, is not particularly sensible; the steps become
oddly split between the OutgoingWebhookWorker, `do_rest_call`, and the
`OutgoingWebhookServiceInterface`.
Make the `OutgoingWebhookServiceInterface` in charge of building,
making, and returning the request in one method; another method
handles extracting content from a successful response. `do_rest_call`
is responsible for calling both halves of this, and doing common error
handling.
Structurally, exception, failure_message, and status_code are mutually
exclusive in how this function is called, and it's best for the
function's flow to represent that.
The message from the bot which triggered the 407 error message notifies
the bot owner about the exceptions as well in the error message. This
commit handles it more gracefully and shows a generic message.
The messages from the bot which were triggered by the outgoing_webhooks
didn't have the bot name in them. This commit adds the bot name to it
and makes the corresponding changes in the tests.
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.
These weren’t wrong since orjson.JSONDecodeError subclasses
json.JSONDecodeError which subclasses ValueError, but the more
specific ones express the intention more clearly.
(ujson raised ValueError directly, as did json in Python 2.)

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.
Fixes#2665.
Regenerated by tabbott with `lint --fix` after a rebase and change in
parameters.
Note from tabbott: In a few cases, this converts technical debt in the
form of unsorted imports into different technical debt in the form of
our largest files having very long, ugly import sequences at the
start. I expect this change will increase pressure for us to split
those files, which isn't a bad thing.

Prevent `JsonableError(_("Missing content"))` from
ever being triggered.
That error wasn't handle by anything, and thus just threw a 500, as
it's not a response to an HTTP request.
The right fix is to adjust the caller to ban the empty string in
content (or content that strips to the empty string).
Closes#15145.
request_retry and notify_bot_owner don't use request_data so might
as well not send it to them at all.

Using the Python Standard Library's abc library and NotImplementedError
we can better define interfaces (this is mainly to improve readability
and consistency).

When more than one outgoing webhook is configured,
the message which is send to the webhook bot passes
through finalize_payload function multiple times,
which mutated the message dict in a way that many keys
were lost from the dict obj.
This commit fixes that problem by having
`finalize_payload` return a shallow copy of the
incoming dict, instead of mutating it. We still
mutate dicts inside of `post_process_dicts`, though,
for performance reasons.
This was slightly modified by @showell to fix the
`test_both_codepaths` test that was added concurrently
to this work. (I used a slightly verbose style in the
tests to emphasize the transformation from `wide_dict`
to `narrow_dict`.)
I also removed a deepcopy call inside
`get_client_payload`, since we now no longer mutate
in `finalize_payload`.
Finally, I added some comments here and there.
For testing, I mostly protect against the root
cause of the bug happening again, by adding a line
to make sure that `sender_realm_id` does not get
wiped out from the "wide" dictionary.
A better test would exercise the actual code that
exposed the bug here by sending a message to a bot
with two or more services attached to it. I will
do that in a future commit.
Fixes#14384
The `event` parameter is never used by `process_success`,
and eliminating it allows us to greatly simplify tests
that are just confusingly passing in events that are
totally ignored.
Apparently, the refactor months ago that introduced finalize_payload
wasn't applied to the outgoing webhook code path, resulting in message
dicts with an unexpected format with no avatar_url and some extra
values that were intended to be internal details not relevant to
external clients.
Because this API is not widely used, we expect there to be little to
no impact of converting this back to matching the `get_messages`
interface, as it once was and has always been intended to be.
The one somewhat tricky detail is that we include both the `content`
and `rendered_content` fields, rather than asking the client to pick
which they want via the `apply_markdown` flag, because there is no
place for the client to configure that setting.
We eliminated use of this function in outgoing_webhook.py in
bdc95b5d72.
Tweaked by tabbott to also eliminate code only used for that mock.

This now sets the user-agent to something like:
ZulipOutgoingWebhook/2.0
(It uses the current ZULIP_VERSION.)
Before this change, the user-agent would be
something like `python-requests/2.18.4`.
Fixes#10741
When you send a message to a bot that wants
to talk via an outgoing webhook, and there's
an error (e.g. server is down), we send a
message to the bot's owner that links to the
message that triggered the error.
The code to produce those links was out of
date.
Now we move the important code to the
`url_encoding.py` library and fix the PM
links to use the more modern style (user_ids
instead of emails). We also replace "subject"
with "topic" in the stream urls.
If we use an outgoing webhook and the web server
responds with `widget_content` in the payload, we
include that in what we send through the send-message
codepath.
This makes outgoing webhook bots more consistent with
generic bots.
For our bots that use GenericOutgoingWebhookService
(which are basically Zulip style bots), we now
include a "content-type" header of "application/json".
We accomplish this by having the service classes
implement their own custom method called
`send_data_to_server`. For the Slack-related
code, we just extracted code from `do_rest_call`,
and then for the Zulip-related code, we added
a `headers` parameter.
If we omit methods in subclasses, they're likely to
be caught by linters or unit tests, and even if they
aren't, raising NotImplementedError doesn't actually
prevent user problems.
I've been fighting these in refactoring, and it's
just been a bunch of busy work, plus comments are
highly likely to bitrot.
