The previous logic was incorrect, in that if `content_type` was set to
None (which happens with Slack/HipChat export, among other things),
then we wouldn't run the `guess_type` logic to auto-detect the
Content-Type to send to S3.
The UserMessage table can be huge, so creating a
bunch of entries in `ID_MAP` can overflow memory.
We don't have any tables that depend on `UserMessage`,
and we don't send the 'id' fields from `zerver_usermessage`
to the database, so re-mapping them was just busy-work.
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.
Apparently, the QUERY_STRING property of the report object wasn't
actually a string; since we only care about its string representation,
we should just stringify it.
Fixes#10745.
Use get_display_recipient to get stream names, and remove the
references to message.stream_name in push_notifications.py which were
added in 97571a203, as the actual stream names were being retrived
only for Message objects associated with public streams.
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The code to produce those links was out of
date.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.
This will help us eliminate camo from our production installs.
Basically it helps us de duplicate some code from upcoming code
which will help us check validity of a camo url.
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.
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
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.
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.
This is a prepartory commit for the upcoming changes. It was meaningful
to extract this one out because this function is essentially a condition
check on whether a given url is one of the user_uploads or an external
one. Based on its value we decide whether a url must be thumbnailed or
not and thus this function will also be used in an upcoming commit
patching lib/thumbnail.py to do the same check before thumbnail url
generation.
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.
The Zulip API is to be used on both development and production
servers, and really we just need to talk about zuliprc files.
There's a similar issue for the JS docs, but we need to fix the
copy/paste issues with those as well.
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.
We use UserMessageLite to avoid Django overhead, and we
do updates in chunks of 10000. (The export may be broken
into several files already, but a reasonable chunking at
import time is good defense against running out of memory.)
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.
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.
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.
Previously, Zulip did not correctly handle the case of a mobile device
being registered with a push device token being registered for
multiple accounts on the same server (which is a common case on
zulipchat.com). This was because our database `unique` and
`unique_together` indexes incorrectly enforced the token being unique
on a given server, rather than unique for a given user_id.
We fix this gap, and at the same time remove unnecessary (and
incorrectly racey) logic deleting and recreating the tokens in the
appropriate tables.
There's still an open mobile app bug causing repeated re-registrations
in a loop, but this should fix the fact that the relevant mobile bug
causes the server to 500.
Follow-up work that may be of value includes:
* Removing `ios_app_id`, which may not have much purpose.
* Renaming `last_updated` to `data_created`, since that's what it is now.
But none of those are critical to solving the actual bug here.
Fixes#8841.
We now allow outgoing webhooks to provide us a
"content" field, which is probably a more guessable
name than "response_string", particularly for folks
that use our other bot-related APIs. And we don't
modify content as we do response_string, i.e. no
"Success!" prefix.
If we're not too concerned about backward compatibility,
we can do a subsequent commit that makes "content"
and "response_string" true synonyms and get rid of
the "Success!" prefix, which was probably accidental
to begin with.
This commit starts by changing the third
argument of send_response_message to be a Dict
instead of a string, so that the data can be more
structured going forward.
That change makes the 2nd/3rd parameters both be
dicts, so to be defensive, I now have all the callers
pass in explicit keyword names. And then I rename
message to message_info, so that the callers have
more clear code.
And that changes the implementation inside of
send_response_message() a bit.
Sorry this commit is a bit coarse, but the intermediate
commits would have been kind of ugly, too.
At the end of the day, it's pretty simple:
bot_id: never changed
message_info: just renamed from message
response_data: is a Dict with the key of "content"
And the innards of send_response_message() are basically
simply dictionary lookups and function calls.
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.
The code was needlessly querying the DB to get full
objects for entities where we only needed user_id,
realm_id, and stream_id.
With my test data of ~1000 records this sped up the
function from ~8s to ~0.5s. The speedup would probably
be even more for larger data sets.
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.
If any user had sent the reply to the welcome bot recommended by our
tutorial, then the Zulip export/import process didn't work properly,
because we weren't including (and then remapping) the recipient ID for
sending PMs to the cross-realm bots. This commit fixes that gap, by
recording the necessary data on the export side, and doing the
appropriate remapping on the import side.
Previously, our realm import logic only did the special remapping
logic for the original notifications_stream_id; when we added the new
signup_notifications_stream_id field, we neglected to handle it in the
same way.
In the event that two processes are racing to be the
first to load data from zulip.yaml, we now make the
race scenario be duplicated effort instead of having
the second racer get an attribute error on `data`.
We do this by declaring victory only after setting
`data`. "Declaring victory" in this case is a matter
of setting `last_update`.
We are still possibly vulnerable to corrupted data
here, so we should investigate a mutex, or just
read the data on every call (but it's strangely
expensive, almost 3.5s on my instance), or converting
the YAML to code before launching the server.
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.
We also remove some unreachable code. Calling
split() always returns at least one token, even
if it's just the empty string. This is tested
directly on this commit, plus messages with
empty content get rejected pretty early in
the execution path.
In user type custom field, field value is list of user ids. We weren't
converting list to json object in update event payload. This throws
error in frontend, cause we store stringify representation of custom
field value. Therefore, after update event is recieved field-value-
type gets updated to array from string which throws json parsing error.
Having HTML (or HTML-like) content in the examples was making parts of
the content invisible, since the browser identified them as HTML tags
rather than verbose text.
There are some endpoints that don't fall into the currently available
categories, so this new function will be used for calling the tests for
server and realm-related endpoints.
Using early-exit here allows us to more easily
comment why there are certain exemptions to
this logic.
We also only require callers to pass in realm,
not the whole user object.
Since this class was built, folks have always chosen
to subclass JsonableError for situations where
the default of ErrorCode.BAD_REQUEST is insufficient.
So now we simplify the use cases, which also gets
us 100% coverage on this core module.
This commit add FIELD_TYPE_CHOICES_DICT to page_params and replace
FIELD_TYPE_CHOICES.
FIELD_TYPE_CHOICES_DICT includes all field types with keyword, id
and display name. Using this field-type-dict, we can access field
type information by it's keyword, and remove all static use of
field-type'a name or id in frontend.
This commit also modifies functions in js where this page_params
field-types is used.
This commit modifies FIELD_TYPE_DATA dict in `CustomProfileField`
model to store keyword of field types. And create new dict
FIELD_TYPE_CHOICES_DICT to store all field type information
by field type keyword, i.e. id, name.
This is preparatory commit to remove all static use of field
types in frontend and access field type with keyword instead
of display name.
This prevents leaking some variables into an already
cluttered function.
We also add test coverage for what's now an
early-exit condition in the new function--we exempt
public MIT streams from these events.
This change was partially driven by a quirk in Python
where peephole optimizations make `continue` lines
appear not to be covered.
I also think it's generally a good idiom to extract
functions for loop bodies when they don't actually
accumulate values or maintain other state. With this
commit we now prevent potential bugs for vars like
`is_stream` leaking between loop iterations.
We simulate a race condition by mocking create_user
to actually create a user, but then raise an
IntegrityError (as if another process had actually
created the user, not our test).
I also changed the real code to use explicitly
named parameters.
I don't understand why this didn't cause test failures in CI; this
change was clearly required and test_change_realm_property was failing
consistently for me locally.
Our get_streams_traffic function used to query
all streams in the StreamCount table if you
passed in `None` for `streams`.
Now we require that you pass in a list of
stream_ids.
I don't know how much work this will save
the database, since probably the bulk of
the work is aggregating. If we need to fine
tune DB performance, we could possibly add
`realm` as an argument and add it to the filter.
What we'll immediately get, for large multi-realm
installations, is less data over the wire and
less work for the ORM.
The prior code uses an awkward idiom that
pre-dates the `exists()` function, and it
had an unreachable line of code.
The new version should be faster, since we
don't create a throwaway heavy Django object
or send needless data over the wire.
This functions appears to be redundant to
`access_stream_by_name`. The only
meaningful line of code in the function that we're
removing, the code that raises an error,
appears to be unreachable, despite reasonably
extensive tests.
The only thing the function was restricting
was that the case where the bot's owner was
unsubscribed to a private stream, which
is already locked down in
`access_stream_by_name` calls inside of
`patch_bot_backend`.
This commit increases test coverage
by removing unreachable code.
It's possible this function had
some theoretical value before we
introduced the `require_non_guest_human_user`
decorator to the `patch_bot_backend`
view, since in theory the bot itself
could have subscribed to a stream that
the owner didn't subscribe to. Even
then it's not clear that allowing the
bot to set that as a default stream
would have been harmful, since they
can already access it.
We want our methodology for extracting the last message
id to be consistent, particularly in terms of how we
handle edge cases. (I'll concede that the
`bulk_remove_subscriptions` codepath never hits that
corner case in practice, but it's harmless to handle
the theoretical case.)
It may also be nice to have this function show up
clearly in profiling.
This also adds some direct testing to the function.
It's not clear to me why we don't use `latest('id')`
in the implementation, but that's outside the scope
of this commit.
This de-clutters check_message a bit and also makes
it easy to audit our rules for who can write to a
stream.
Also, this works around a bug with Python where its
optimizations for the `pass` instruction make them
not appear to run and show up as uncovered in
coverage reports.
Fixes#10124.
Users in the waiting period category cannot subscribe other users to
a stream. When a user tries to mention another unsubscribed user, a
warning message appears with a subscribe button on it to subscribe
the other user.
This commit removes the subscribe button and changes the warning text
for users in the waiting period category.
Right now it only has one function, but the function
we removed never really belonged in actions.py, and
now we have better test coverage on actions.py, which
is an important module to get to 100%.
In this commit we fix a bug due to which url preview images for urls
to custom emojis, realm icons or user avatars appeared broken when
such urls would be part of a Zulip message.
This is a preparatory commit to fix a bug in which a user posts
a link of custom emoji, user avatar or realm icon in a Zulip
message.
In this commit we are just adjusting the url generation in the
backend to have the '/user_uploads/' in the encrypted url generated
which the user is supposed to be redirected to and therefore
essentially reaching thumbor with the encrypted url.
This is necessary because 'user_uploads' and 'user_avatars' (or any
other item under 'user_avatars' endpoint) have a different folder
location under the local file storage backend. 'user_uploads'
endpoint's stuff is stored in a 'files' directory whereas stuff
'user_avatars' endpoint's stuff is stored in a 'avatars' directory.
Thumbor needs to know from which directory a particular local file
needs to be retrieved and therefore the zthumbor/loaders.py adds
a prefix location for the directory.
Since in an upcoming commit we are going to add user_avatars
directory location 'avatars' folder as a prefix this preparatory
commit helps simply doing the changes.
The 'last_modified' value in emoji records is
needed for uploading the file to the S3 backend.
We set the same in the function 'import_uploads_s3'.
We also have to remove the keyword 'last_modified'
while building the RealmEmoji dict, as it is not
a field which exists in RealmEmoji objects.
This uses the recently introduced active_mobile_push_notification
flag; messages that have had a mobile push notification sent will have
a removal push notification sent as soon as they are marked as read.
Note that this feature is behind a setting,
SEND_REMOVE_PUSH_NOTIFICATIONS, since the notification format is not
supported by the mobile apps yet, and we want to give a grace period
before we start sending notifications that appear as (null) to
clients. But the tracking logic to maintain the set of message IDs
with an active push notification runs unconditionally.
This is designed with at-least-once semantics; so mobile clients need
to handle the possibility that they receive duplicat requests to
remove a push notification.
We reuse the existing missedmessage_mobile_notifications queue
processor for the work, to avoid materially impacting the latency of
marking messages as read.
Fixes#7459, though we'll need to open a follow-up issue for
using these data on iOS.
Fixes a regression introduced in 23246ff816.
However, we'll be shortly removing this feature, since it's legacy
support for an app that no longer is supported.
Following recent testing flakes that were traced down to this not
having been called causing `receiver_is_off_zulip` to depend on test
ordering, it makes sense to centralize this.
I think it should always have been in ZulipTestCase; it appears the
reason it wasn't from the beginning was that originally only
test_events.py interacted with it, and do_test there still needs to
call this directly (because it can be called multiple times within a
single test). And then we did the wrong thing as expanded use of
Tornado event_queue code in tests to more of the codebase.
The s3 import code path made a hard assumption about `user_profile_id`
being set (we'd already fixed this in the local uploads code path).
Ideally, it should be, and I've opened #10268 for fixing that, but for
now this is how it needs to work.
Private messages are not supported in Slack-format webhook.
Instead of raising a NotImplementedError, we warn the user
that PM service is not supported by sending a message to the
user.
Added tests for the same.
Fixes#9239
After the messages have been imported, set the rendered_content of the
messages instead of leaving its value to be 'None'.
This is important to ensure that:
(1) Performance for users is good after completing the import.
(2) The database's full-text indexes have all of the imported messages
(which only happens properly when Message rows have their
rendered_content field edited).
Fixes#9168.
The "/stats" command doesn't actually do anything
interesting yet, and it also writes to the message
feed instead of replying directly to the user.
The history of this command was that it was
written during a PyCon sprint. It was mainly intended
as an example for subsequent slash commands. The
ones we built after "/stats" have sort of outgrown
"/stats" and don't follow the original structure
for "/stats". (The "/day", "/ping", and "/settings"
commands were built shortly after.)j
We probably want to ressurect "/stats" fairly soon,
after figuring out some useful stats and refining
the UI.
As you can see from this commit, resurrecting the
code here shouldn't be too difficult, but it
may actually be pretty rare that we just translate
slash commands into fleshed out messages.
Since otp_encrypt_api_key only encrypts API keys, it doesn't require
access to the full UserProfile object to work properly. Now the
parameter it accepts is just the API key.
This is preparatory refactoring for removing the api_key field on
UserProfile.
random_api_key, the function we use to generate random tokens for API
keys, has been moved to zerver/lib/utils.py because it's used in more
parts of the codebase (apart from user creation), and having it in
zerver/lib/create_user.py was prone to cyclic dependencies.
The function has also been renamed to generate_api_key to have an
imperative name, that makes clearer what it does.
Now reading API keys from a user is done with the get_api_key wrapper
method, rather than directly fetching it from the user object.
Also, every place where an action should be done for each API key is now
using get_all_api_keys. This method returns for the moment a single-item
list, containing the specified user's API key.
This commit is the first step towards allowing users have multiple API
keys.
python-twitter was consuming a significant amount of import time.
However, this commit seems to not save any time at all, probably
because its recursive dependencies are imported elsewhere in Zulip.
Renaming a user group to a name shared by other group wasn't a scenario
handled by the backend, and the server errored whenever this was
attempted.
Now a json_error is returned, letting the user know that a user group
with that name already exists.
We found out in #9953 that, appparently, loading the OpenAPI file was
taking abut a 5% of the Zulip server startup time.
Since in many cases (especially in development) having the file loaded
won't be necessary at all, we read it on the first time data from the
OpenAPI spec is needed.
Tweaked by tabbott to add a test.
Automatically detect if the OpenAPI spec file has been modified since
the last time it was loaded into memory, and if it has, automatically
reload it to have the latest version.
This feature is designed with development environments in mind. The main
benefit is being able to see the changes made to the OpenAPI document
without needing to restart the development server, which is tedious and
slows the documentation workflow down.
When last user(only in case of admin) unsubscribe from private stream,
stream page doesn't get updated. Cause we delete the private stream
as soon as last user unsubscribe from stream.
So `sub` get undefined in frontend, cause that stream is deleted
before unsubscribe-user-from-stream event is received.
Fix this by changing order of events sent to frontend. Event
`subscription: remove` should be sent before `stream: delete` event
from backend.
This fixes a bug where administrators couldn't remove private
unsubscribed streams from the "default streams" list, because
access_stream_by_name didn't give them access to the stream object.
This commit adds 'resize_gif()' function which extracts each frame,
resize it and coalesces them again to form the resized GIF while
preserving the duration of the GIF. I read some stackoverflow
answers all of which were referring to BiggleZX's script
(https://gist.github.com/BigglesZX/4016539) for working with animated
GIF. I modified the script to fit to our usecase and did some manual
testing but the function was failing for some specific GIFs and was not
preserving the duration of animation. So I went ahead and read about
GIF format itself as well as PIL's `GifImagePlugin` code and came up
with this simple function which gets the worked done in a much cleaner
way. I tested this function on a number of GIF images from giphy.com
and it resized all of them correctly.
Fixes: #9945.
This adds a new function called handle_remove_push_notification in
zerver/lib/push_notifications.py which requires user_profile id and
the message id which has to be removed in the function.
For now, the function only supports GCM (and is mostly there for
prototyping).
The payload which is being delivered needs to contain the narrow
information and the content of the message.
This should make it much simpler for the mobile apps to line up the
data from server_settings against the data in the notifications.
Addresses part of #10094.
This ensures that the format of this data structures matches that for
in-realm bots in the main users data structure (including avatars,
etc.).
Fixes#10138.
For realms that don't have any presence-active users, we know for a
fact that there aren't any active clients that will be reloading just
after the server restarts, so we can skip filling the cache with data
related to that realm.
For zulipchat.com, this results in a significant performance
optimization for the recipient and stream caches, and a moderate
performance improvement for the user caches as well.
Private messages make up the bulk of Recipient objects. While private
messages are ~50% of messages, if you weight by messages received
(which is what is important for message-loading performance), it's
pretty strongly balanced towards stream messages.
We don't need to include long-term idle or other inactive users here,
since fetching them consumed to vast majority of the time.
(On chat.zulip.org, this decreased the runtime for populating the user
cache by 5x, removing only users we're unlikely to need to access).
This doesn't seem to have a huge performance downside (less than 1s
extra time for loading / on chat.zulip.org), and it means the
possibility of users having so many unreads that we get weird/buggy
behavior is much more unlikely to exist.
We'll still want a better experience for users who somehow go over
this limit, but it can be pretty firmly "you need to go mark some
things as read".
This renames Realm.show_digest_email field to
digest_emails_enabled, for greater clarity as to what it does
just from seeing the setting name, without having to look it up.
Fixes part of #10042.
