I remove `is_force` from `file_or_package_hash_updated`
and modernize its mypy annotations.
If `is_force` is `True`, we just now run the thing
we want to force-run without having to call
`file_or_package_hash_updated` to expensively
and riskily return `True`.
Another nice outcome of this change is that if
`file_or_package_hash_updated` returns `True`,
you can know that the file or package has
indeed been updated.
For the case of `build_pygments_data` we also
skip an `os.path.exists` check when `is_force`
is `True`.
We will short-circuit more logic in the next
few commits, as well as cleaning up some of
the long/wrapper lines in the `if` statements.
This is be useful for the mobile and desktop apps to hand an uploaded
file off to the system browser so that it can render PDFs (Etc.).
The S3 backend implementation is simple; for the local upload backend,
we use Django's signing feature to simulate the same sort of 60-second
lifetime token.

For some mobile use cases, 15 seconds is potentially too short for a
busy+slow device to open a browser and fetch the URL. 60 seconds is
plenty, and doesn't carry a materially increased security risk.
When creating a webhook integration or creating a new one, it is a pain to
create or update the screenshots in the documentation. This commit adds a
tool that can trigger a sample notification for the webhook using a fixture,
that is likely already written for the tests.
Currently, the developer needs to take a screenshot manually, but this could
be automated using puppeteer or something like that.
Also, the tool does not support webhooks with basic auth, and only supports
webhooks that use json fixtures. These can be fixed in subsequent commits.
The Redis-based rate limiting approach takes a lot of time talking to
Redis with 3-4 network requests to Redis on each request. It had a
negative impact on the performance of `get_events()` since this is our
single highest-traffic endpoint.
This commit introduces an in-process rate limiting alternate for
`/json/events` endpoint. The implementation uses Leaky Bucket
algorithm and Python dictionaries instead of Redis. This drops the
rate limiting time for `get_events()` from about 3000us to less than
100us (on my system).
Fixes#13913.

Right now, the message is "Invalid characters in emoji name" when
the emoji_name is empty. Changing check_valid_emoji_name() in
zerver/lib/emoji.py which validates the name to accomodate the case
of missing name. The new message is "Emoji name is missing".

This adds a new realm setting: default_code_block_language.
This PR also adds a new widget to specify a language, which
behaves somewhat differently from other widgets of the same
kind; instead of exposing methods to the whole module, we
just create a single IIFE that handles all the interactions
with the DOM for the widget.
We also move the code for remapping languages to format_code
function since we want to preserve the original language to
decide if we override it using default_code_clock_language.
Fixes#14404.
Semaphore has currently has two different versions of their product -
Classic and 2.0. This commit adds support for Semaphore 2.0, along side
Semaphore Classic, using the same webhook. This would let the integration
work seamlessly for users who have already configured a Zulip integration in
their Semaphore 2.0 projects.
Semaphore 2.0 currently only supports GitHub and their payloads do not
contain URLs for common entities like commits, pull requests and tags. We
construct URLs for them using templates, but also try to support other
services by providing notifications without URLs.
Closes#14171

If we had a rule like "max 3 requests in 2 seconds", there was an
inconsistency between is_ratelimited() and get_api_calls_left().
If you had:
request #1 at time 0
request #2 and #3 at some times < 2
Next request, if exactly at time 2, would not get ratelimited, but if
get_api_calls_left was called, it would return 0. This was due to
inconsistency on the boundary - the check in is_ratelimited was
exclusive, while get_api_calls_left uses zcount, which is inclusive.
time_reset returned from api_calls_left() was a timestamp, but
mistakenly treated as delta seconds. We change the return value of
api_calls_left() to be delta seconds, to be consistent with the return
value of rate_limit().
The information used to be stored in a request._ratelimit dict, but
there's no need for that, and a list is a simpler structure, so this
allows us to simplify the plumbing somewhat.
That's the value that matters to the code that catches the exception,
and this change allows simplifying the plumbing somewhat, and gets rid
of the get_rate_limit_result_from_request function.
This commit contains a few clean ups:
* In order to scale better for adding multiple commands,
the message formatting and setting switch logic was
extracted to its own function.
* The command lists were removed, as the frontend parses
the slash command from the compose box, and only sends
a single command to the backend for any given command
alias typed.
* The `switch_command` logic was removed because, given
the aforementioned fact, the index of the command will
always be the same. Thus the switch command will always
be the same.
* Switched to using early returns as opposed to nested
conditionals. Along with removing single use variable
declarations.
This commit reuses the existing infrastructure for moving a topic
within a stream to add support for moving topics from one stream to
another.
Split from the original full-feature commit so that we can merge just
the backend, which is finished, at this time.
This is a large part of #6427.
The feature is incomplete, in that we don't have real-time update of
the frontend to handle the event, documentation, etc., but this commit
is a good mergable checkpoint that we can do further work on top of.
We also still ideally would have a test_events test for the backend,
but I'm willing to leave that for follow-up work.
This appears to have switched to tabbott as the author during commit
squashing sometime ago, but this commit is certainly:

This simplifies the update_display_settings endpoint to use REQ for
validation, rather than custom if/else statements.
The test changes just take advantage of the now more consistent
syntax.
This changes the payload that is used
to populate `page_params` for the webapp,
as well as responses to the once-every-50-seconds
presence pings.
Now our dictionary of users only has these
two fields in the value:
- activity_timestamp
- idle_timestamp
Example data:
{
6: Object { idle_timestamp: 1585746028 },
7: Object { active_timestamp: 1585745774 },
8: Object { active_timestamp: 1585745578,
idle_timestamp: 1585745400}
}
We only send the slimmer type of payload
to clients that have set `slim_presence`
to True.
Note that this commit does not change the format
of the event data, which still looks like this:
{
website: {
client: 'website',
pushable: false,
status: 'active',
timestamp: 1585745225
}
}
This commit migrates zulip outging webhook payload to
/zulip-outgoing-webhook:post in OpenAPI.
Since this migrates the last payloads from api/fixtures.json to
OpenAPI, this commit removes api/fixtures.json file and the functions
accessing the file.
Tweaked by tabbott to further remove an unnecessary conditional.
This is critical for importing the very first realm into an empty
server, since in 27b15a9722, we changed
the model to create the internal realm when the first real realm would
be created, but neglected the data import code path.
The distinction between ValueError and TypeError
is not useful in these functions:
- extract_stream_indicator
- extract_private_recipients (or its callees)
These are always invoked in views to validate
user input.
When we use REQ to wrap the validators, any
Exception gets turned into a JsonableError, so
the distinction is not important.
And if we don't use REQ to wrap the validators,
the errors aren't caught.
Now we just let these functions directly produce
the desired end result for both codepaths.
Also, we now flag the error strings for translation.
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.
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.
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.
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.
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.
