This setting is being overridden by the frontend since the last
commit, and the security model is clearer and more robust if we don't
make it appear as though the markdown processor is handling this
issue.

Zulip's modal_link markdown feature has not been used since 2017; it
was a hack used for a 2013-era tutorial feature and was never used
outside that use case.
Unfortunately, it's sloppy implementation was exposed in the markdown
processor for all users, not just the tutorial use case.
More importantly, it was buggy, in that it did not validate the link
using the standard validation approach used by our other code
interacting with links.
The right solution is simply to remove it.
This makes it relatively easy for a system administrator to
temporarily override these values after a desktop app security
release that they want to ensure all of their users take.
We're not putting this in settings, since we don't want to encourage
accidental long-term overrides of these important-to-security values.
Previously, we only printed the test-case when we had an assertion error.
With this change, we also include timeout errors as well as any other
causes for failure.
We now have Hamlet, not Othello, send the message
to Othello's bot, since that's a more interesting
test and less likely to lead to a false positive.
And then we simplify the recipient check to avoid
the strange mypy mess as well as possible false
negatives.
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
If we have an old event that's missing the field
`sender_delivery_email`, we now patch it at the top
of `process_message_event`, rather than for each call
to `get_client_payload`. This will make an upcoming
commit a bit easier to reason about. Basically, it's
simpler to shim the incoming event one time rather
than doing it up to four times. We know that
`get_client_payload` is non-destructive, because it
does a deepcopy.
We now validate the message data explicitly, rather
than comparing it to the event data. This protects
us from false positives where we were only validating
that the request data was a mutated version of the
event message data. (We'll have a commit soon that
fixes a mutation-related bug.)
This code is only used in one test, and having
the indirection of setUp partly obscured a
problem with the fact that our event message
is actually a wide dict that gets mutated
by `build_bot_request`. We'll fix that soon,
but this is a pure code move for now.
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.
In zulip.yaml simple json success response which only contains 'msg'
and 'result' properties has been described repeatedly in multiple
endpoints. Instead, use SimpleSuccess template for such responses
to increase code modularity and reusablility.
Migrate "call_on_each_event" from api/arguments.json to
/events:real-time in OpenAPI.
This is a bit of a hack, but it lets us eliminate this secondary
arguments.json file, which is probably worth it.
Tweaked by tabbott to fix various formatting issues in the original
documentation while I was looking at it.
Most part of "/message/{message_id}" is migrated to OpenAPI. This commit
migrated the remaning payload "update-message-edit-permission-error"
from "api/fixtures.json" to OpenAPI. This commit also fixes an error
schema in "zulip.yaml" for this payload.
We've had a bug for a while that if any ScheduledEmail objects get
created with the wrong email sender address, even after the sysadmin
corrects the problem, they'll still get errors because of the objects
stored with the wrong format.
We solve this by using FromAddress placeholders strings in
send_future_email function, so that ScheduledEmail objects end up
setting the final `from_address` value when mail is actually sent
using the setting in effect at that time.
Fixes#11008.
This refactors get_single_user to use get_user_by_id instead of
call_endpoint. Doing so is only possible now that we've upgraded
python-zulip-api to a version with the new function.
Overall, this change eliminates a lot of
optional parameters and conditionals, plus
some legacy logic related to caches.
For all the places we are just editing topics,
we now just call `check_topic` to see that
the topic got updated.
For places where the topic edit failed, we
just inline the checks that message still
has the old topic and content.
And then for successful **content** edits,
we now do a more rigorous, more sane check
that the messages are properly cached. The
old code here had evolved from 2013 into
something that didn't really make much sense
in the context of editing topics.
Now we are literally pulling data from the
cache and making sure it's valid, rather
than trying to poorly simulate the two
codepaths related to dispatching message
events and fetching messages. Some of the
history here was that when I introduced
`MessageDict` several years ago, I did a
lot of code sweeping and didn't analyze every
single test to make sure it's still valid,
plus some of the tests still had some value
for catching regressions. A recent commit
now gets us coverage on that a lot more
explicitly, rather than in passing.
See the comment in the test for a thorough explanation.
In brief, this test makes sure that the events codepath
for messages produces the same results as the fetch
codepath.
And this sets us up to simplify another test that kind
of poorly tried to do the same thing in passing. (In
fairness the test was really ancient and preceded a lot
of later work that we did here.)
When we are fetching messages, we need to hydrate
stream names into the messages for legacy reasons.
(Ideally, we could skip this step for the webapp
and modern mobile clients, since they really only
need stream_ids, but we're not there yet.)
We keep a recipient cache that maps recipient ids
to stream names.
When we populate that cache, we now use `values(...)`
to avoid fat objects and extra DB work.
Note that we are already using a similar technique
for hydrating PM/huddle recipients.
For event types that we don't yet support, like worklog_created (and
likely many more in the future), it doesn't make sense to call a
function that only parses issue events correctly.
The previous system for documenting arguments was very ugly if any of
the examples or descriptions were wrong. After thinking about this
for a while, I concluded the core problem was that a table was the
wrong design element to use for API parameters, and we'd be much
better off with individual card-type widgets instead.
This rewrites the API arguments documentation implementation to use a
basic sort of card-like system with some basic styling; I think the
result is a lot more readable, and it's a lot more clear how we would
add additional OpenAPI details (like parameter types) to the
documentation.
This is a full-stack change:
- server
- JS code
- templates
It's all pretty simple--just use stream_id instead
of stream_name.
I am 99% sure we don't document this API nor use it
in mobile, so it should be a safe change.
This commit modifies 'zerver/lib/bot_lib.py' to decouple the
user-controllable 'service_name' parameter from the value that is
passed in to 'import_module'. This is done as a precautionary
hardening.
This commit introduces two new functions in 'url_encoding.py' which
centralize two common patterns for constructing redirect URLs. It
also migrates the files using those patterns to use the new
functions.
After subscribing a stream email address to a Mailman email list
and receiving a message from it (using the polling configuration
with an Exim + Dovecot mailserver), the following error message
is emitted by Zulip:
Logger zerver.lib.email_mirror, from module zerver.lib.email_mirror line 77:
Error generated by Anonymous user (not logged in) on zulip deployment
Sender: "Foo Bar" <foo@example.com>
To: No recipient found
Missing recipient in mirror email
This is because the To: header on the received email corresponds
to the email list, and there are no other headers to indicate the
final recipient, apart from the "Envelope-To" header added by
Exim. To resolve this problem, the commit adds "Envelope-To" to
the list of headers to check for a match.
The function `prepare_login_url_and_headers` returns a register
link for any value of `is_signup` unless it's not none.
This commit changes it to a boolean for that function and other
functions using it so that it becomes much clearer when a
register link will be returned.
Also, all occurrences of `is_signup='1'` are changed to
`is_signup=True` to make the code consistent with the above change.
This allows us to block use of the desktop app with insecure versions
(we simply fail to load the Zulip webapp at all, instead rendering an
error page).
For now we block only versions that are known to be both insecure and
not auto-updating, but we can easily adjust these parameters in the
future.
This improves the error handling for invalid values of the
propagate_mode parameter to our message editing endpoints.
Previously, invalid values would just work like change_one rather than
doing nothing.
setup_event_queue() generates some logs about loaded event queues, and
it's good for the logging system to have access to the port at that
point already.
