We now attach zulip_db_data to the markdown engines
for classes that need it. This was the last remaining
global we had, so we remove `arguments.py` here.
The Markdown processor makes it fairly simple for
the helper classes to access the `md` engine. We
now write `_md_engine.zulip_message` to avoid having
the current message in the global namespace.
Note that we do reuse engines for multiple messages,
but each engine is specific to a realm. And we therefore
avoid even the theoretical possibility of leaking message
data between realms.
We were building the same link regex every time
we build a Markdown engine, which happens twice
per realm. It's an expensive operation due to
the complexity of the regex and us reading a file.
This is a preparator refactor for supporting hosting different Tornado
processes on different servers; to look up which Tornado server we
should be sending the event to, we'll need the realm object.
This should make it possible for there to safely be multiple Tornado
processes running on different ports on the same system.
It may also fix a rare race bug in development, where previously, it
was possible for the Tornados processes for Casper and the main
development server to interfere; I haven't investigated whether this
was a real bug or not, but now those two services will use independent
Tornado files.
We still need to add something to direct traffic between the different
Tornado processes.
This is mostly an extraction, but it does change the
way we calculate `content`. We append the markdown
links from ALL files to any content that came in the
message itself.
Separating this out also allows us to add more
test coverage for the extracted code.
We now use subscriber_map for building UserMessage
rows in Slack/Gitter conversions.
This is mostly designed to simplify the code, rather
than having to scan the entire subscribers for each
message.
I am guessing this will improve performance for most
conversions. We sort small lists on every message,
in order to be deterministic, but the sorting cost
is probably more than offset by avoiding the O(N)
scans across all subscriptions. Also, it's probably
negligible in the grand scheme of things, compared
to JSON parsing, file I/O, etc.
This commits also fixes some typos with mentioned_users_id ->
mentioned_user_ids and cleans up a test a bit as well.
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.
This supports guest user in the user-info-form-modal as well as in the
role section of the admin-user-table.
With some fixes by Tim Abbott and Shubham Dhama.
The purpose of this commit is to pass information
to the frontend whether the message response recieved
has been limited due to plan restrictions or not.
To implement this, the backend for limiting the message
history had to be rewritten as we used to fetch
only the message rows whose id was greater than
first_visible_message_id. The filtered rows gives us
no information on whether the message history was
limited or not. So the backend was rewritten to not
do any restriction of limiting the message rows while
making the query. The limiting of rows is now done in
post_process_limited_query which will also return back
the value of history_limited flag.
Tweaked by tabbott to note a few cases where the results are
incorrect. I'm merging this despite those, because those cases don't
impact the correctness of the feature, and it may have tricky
performance implications to fix correctly.
Apparently, we weren't actually checking that found_oldest had the
correct value; fortunately, this didn't actually result in a problem,
because the values were always correct. But this will be important as
we start extending this test.
This is a preparatory commit which will help us with removing camo.
In the upcoming commits we introduce a new endpoint which is based
out on the setting CAMO_URI. Since camo could have been hosted on
a different server as well from the main Zulip server, this change
will help us realise in tests how that scenerio might be dealt with.
Also, rename get_alert_from_message to get_gcm_alert.
With the implementation of the and get_apns_alert_title and
get_apns_alert_subtitle, the logic within get_alert_from_message
is only relevant to the GCM payload, so we adjust the name
accordingly.
Progresses #9949.
Resolves https://github.com/zulip/zulip-mobile/issues/1316.
The string that is returned from get_alert_from_message is
dependent upon the same message that is passed into get_apns_payload
and get_gcm_payload. The contents of those payloads that are tested via
TestGetAPNsPayload and TestGetGCMPayload, which makes the tests for
get_alert_from_message redundant.
Also, simplify the logic by removing the last elif conditional.
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.
The test named `test_archiving_messages_with_attachment`
started flaking recently. We use sets for comparison
instead of lists to avoid arbitrary sorting differences.
Bots are not allowed to use the same name as
other users in the realm (either bot or human).
This is kind of a big commit, but I wanted to
combine the post/patch (aka add/edit) checks
into one commit, since it's a change in policy
that affects both codepaths.
A lot of the noise is in tests. We had good
coverage on the previous code, including some places
like event testing where we were expediently
not bothering to use different names for
different bots in some longer tests. And then
of course I test some new scenarios that are relevant
with the new policy.
There are two new functions:
check_bot_name_available:
very simple Django query
check_change_bot_full_name:
this diverges from the 3-line
check_change_full_name, where the latter
is still used for the "humans" use case
And then we just call those in appropriate places.
Note that there is still a loophole here
where you can get two bots with the same
name if you reactivate a bot named Fred
that was inactive when the second bot named
Fred was created. Also, we don't attempt
to fix historical data. So this commit
shouldn't be considered any kind of lockdown,
it's just meant to help people from
inadvertently creating two bots of the same
name where they don't intend to. For more
context, we are continuing to allow two
human users in the same realm to have the
same full name, and our code should generally
be tolerant of that possibility. (A good
example is our new mention syntax, which disambiguates
same-named people using ids.)
It's also worth noting that our web app client
doesn't try to scrub full_name from its payload in
situations where the user has actually only modified other
fields in the "Edit bot" UI. Starting here
we just handle this on the server, since it's
easy to fix there, and even if we fixed it in the web
app, there's no guarantee that other clients won't be
just as brute force. It wasn't exactly broken before,
but we'd needlessly write rows to audit tables.
Fixes#10509
Previously, MissedMessageWorker used a batching strategy of just
grabbing all the events from the last 2 minutes, and then sending them
off as emails. This suffered from the problem that you had a random
time, between 0s and 120s, to edit your message before it would be
sent out via an email.
Additionally, this made the queue had to monitor, because it was
expected to pile up large numbers of events, even if everything was
fine.
We fix this by batching together the events using a timer; the queue
processor itself just tracks the items, and then a timer-handler
process takes care of ensuring that the emails get sent at least 120s
(and at most 130s) after the first triggering message was sent in Zulip.
This introduces a new unpleasant bug, namely that when we restart a
Zulip server, we can now lose some missed_message email events;
further work is required on this point.
Fixes#6839.
These test are for the handling of HipChat
sender info. The data formats are somewhat
inconsistent and sometimes require us to
generate "mirror" users, so this is potentially
fragile code if we don't cover it well.
When we create new ids for message rows, we
now sort the new ids by their corresponding
pub_date values in the rows.
This takes a sizable chunk of memory.
This feature only gets turned on if you
set sort_by_date to True in realm.json.
We could migrate all the current PREMIUM_FREE organizations to have more
invites, but this setting mainly affects orgs right as they are starting, so
it's probably fine.
We seemed to have been doing too much of sharpening on the thumbnails.
The purpose of sharpening here was to just counter the softening
effects of a resize on an image but overdoing it is bad.
Value sharpen(0.5,0.2,true) seems to look good for achieving the
best results here on different displays as revealed in the manual
hit and trial based testing.
Thanks to @borisyankov for pointing out the issue and suggesting
the values.
For some webhook endpoints where the third-party API requires us to do
this, the user's API key might appear in error emails through
appearing in the `QUERY_STRING` parameter. Fix that by filtering any
actual content from those; what we usually need for debugging is just
what set of parameters were provided.
Currently, if there is only one admin in realm and admin tries
to updates any non-adminuser's full name it throws error,
"Cannot remove only realm admin". Because in `/json/users/<user_id>`
api check_if_last_admin_is_changed is checked even if property
is_admin is not changed.
This commit fix this issue and add tests for it.
The APNS client libraries (especially the hyper.http20 one) were
determined via profiling to take significant time during the import
process, so we move them to be lazily imported in order to optimize
the overall Zulip import process. This save up to about 100ms in
import time.
These libraries are only used in certain Django processes inside
zulipchat.com, and so are unnecessary both in development as well as
for self-hosted Zulip servers.
We are basically adding a check for url's to be external (belonging
to some 3rd party web site hosting the image) or be one of the
user uploaded files. User uploaded files are served by a separate
endpoint which is /user_uploads/. Any other local url such as
/user_avatars/ or /static/ should never be sent to thumbor for
thumbnailing.
Not sending /user_avatars/ to thumbor for thumbnailing makes sense
because they are already properly thumbnailed and stored properly.
/static/ urls host very few images we use for demo and can be safely
be excluded from thumbnailing.
Before, presence information for an entire realm could only be queried via
the `POST /api/v1/users/me/presence` endpoint. However, this endpoint also
updates the presence information for the user making the request. Therefore,
bot users are not allowed to access this endpoint because they don't have
any presence data.
This commit adds a new endpoint `GET /api/v1/realm/presence` that just
returns the presence information for the realm of the caller.
Fixes#10651.
We don't want really long urls to lead to truncated
keys, or we could theoretically have two different
urls get mixed up previews.
Also, this suppresses warnings about exceeding the
250 char limit.
Finally, this gives the key a proper prefix.
Now that we allow multiple users to have registered the same token, we
need to configure calls to unregister tokens to only query the
targeted user_id.
We conveniently were already passing the `user_id` into the push
notification bouncer for the remove API, so no migration for older
Zulip servers is required.
If cordelia searches on pm-with:iago@zulip.com,cordelia@zulip.com,
we now properly treat that the same way as pm-with:iago@zulip.com.
Before this fix, the query would initially go through the
huddle code path. The symptom wasn't completely obvious, as
eventually a deeper function would return a recipient id
corresponding to a single PM with @iago@zulip.com, but we would
only get messages where iago was the recipient, and not any
messages where he was the sender to cordelia.
I put the helper function for this in zerver/lib/addressee, which
is somewhat speculative. Eventually, we'll want pm-with queries
to allow for user ids, and I imagine there will be some shared
logic with other Addressee code in terms of how we handle these
strings. The way we deal with lists of emails/users for various
endpoints is kind of haphazard in the current code, although
granted it's mostly just repeating the same simple patterns. It
would be nice for some of this code to converge a bit. This
affects new messages, typing indicators, search filters, etc.,
and some endpoints have strange legacy stuff like supporting
JSON-encoded lists, so it's not trivial to clean this up.
Tweaked by tabbott to add some additional tests.
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.
This fixes a couple things:
* process_event() is a pretty vague name
* returning tuples should generally be avoided
* we were producing the same REST parameters in both
subclasses
* relative_url_path was always blank
* request_kwargs was always empty
Now process_event() is called build_bot_request(),
and it only returns request data,
not a tuple of `rest_operation` and `request_data`.
By no longer returning `rest_operation`, there are
fewer moving parts. We just have `do_rest_call` make
a POST call.
Before this change, we instantiated base_url into a superclass
of subclasses that returned base_url into a dictionary that
gets returned to our caller.
Now we just pull base_url out of service when we need to make
the REST call.
We move the JSON parsing step into the
higher level function: process_success_response().
In the unlikely event that we'll start integrating
with a solution that doesn't use JSON, we can deal
with that, and for now doing the parsing in one
place will help us make error reporting more
consistent.
In a subsequent commit we'll introduce better
error handling for malformed JSON.
The earlier code here, if it got a payload with
"response_string" as a key, would prefix the
corresponding value with "Success!". We just
want the bot to set its own content.
The code is reorganized here so that process_success()
always produces a value keyed by "content" from
incoming data, and then process_success_response()
doesn't do any fancy munging of the data.
There's no reason to return a failure message in
process_success(), since it's implied to be part of
the success codepath. I didn't look at the full history
of how the strange API evolved, but the second element
of the tuple was clearly noise by the time I got here.
Neither of the subclasses ever set it, and none of the
consumers used it.
This two-line function wasn't really carrying its
weight, and it just made it harder to refactor the
overall codepath.
Eliminating the function forces us to mock at a slightly
deeper level, which is probably a good thing for what
the test intends to do. The deeper mock still verifies that
we're sending the message (good) without digging into
all the details of how we send it (good).
Note that we will still keep around the similarly named
`fail_with_message` helper, which is a lot more useful.
(The succeed/fail scenarios aren't really symmetric here.
For success, there are fewer codepaths that do more complex
things, whereas we have lots and lots of failure codepaths
that all do the same simple thing of replying with a canned
message.)
Before this change subclasses of OutgoingWebhookServiceInterface
would return a raw string as the first element of its return
tuple in process_success(). This is not a very flexible
design, as it prevents the bot from passing extra data like
`widget_content`.
It's also possible in the future that we'll want to let outgoing
bots reply directly to senders who mention them on streams, and
again the original design was overly constrained for that.
This commit does not actually change any functionality yet.
Tweaked by tabbott to use a declared constant rather than just use
5000 in multiple places; this also means we can change the count
without updating translations.
Fixes#10446.
Fixes the urgent part of #10397.
It was discovered that soft-deactivated users don't get mobile push
notifications for messages on private streams that they have configured
to send push notifications.
Reason: `handle_push_notification` calls `access_message`, and that
logic assumes that a user who is a recipient of a message has an
associated UserMessage row. Those UserMessage rows are created
lazily for soft-deactivated users, so they might not exist (yet)
until the user comes back.
Solution: Ensure that userMessage row is created for
stream_push_user_ids and stream_email_user_ids in create_user_messages.
At some point as part of the process of supporting renumbering data,
we changed the structure of our file uploads to expect `path` to match
`s3_path`, with both having the relative path within the overall
hierarchy (including the realm ID). This change updates the more
rarely-used S3 export code path to use that model, fixing a crash when
messages reference an Attachment object with a rewritten path_id.
Note we're no longer using subscriptions_html in the help docs, so no need
to test for it. There is already a test for subscriptions_html in
IntegrationTest.
We start by stripping the ids in front of the name before the database
lookup. This has the advantage of not mentioning anyone if an incorrect
user id and full name combination is specified, as well as not having
the query the database twice, once by fullname and next by id.
Previously, we were storing only the most recent person with the same
full name as others; this commit adds new keys to the dict such that
simply looking by name would get you the newest user with this name,
and the get_user_by_id function can index the remaining users.
This is largely inspired by requests from people not liking the
Google's new emojiset. A lot of people were requesting to revert
back to old blobs emojiset so we are re-enabling this feature
after making relevant infrastructure changes for supporting google's
old blob emojiset and re-adding support for twitter emojiset.
