We are downloading code off the Internet and executing it on the user's device,
so run it sandboxed to avoid potential bad actors.
Since it's impossible to eval() safely in JS and React Native doesn't offer
something akin to Node's vm module, here we are rolling our own.
On Android it uses the Duktape JavaScript engine and on iOS the builtin
JavaScriptCore engine. The extra JS engine is *only* used for evaluating the
downloaded code and returning a JSON string which is then passed back to RN.
- use AbortController for setting the fetch timeout
- use async / await syntax for clarify
- set the default timeout to 5s (previously non-existent, aka 0)
- add ability to load but not evaluate a script
They never worked on mobile and pose an impediment for makinf config.js more
future proof. Specially if we want to move to a non-executable form of
configuration.
This adds an option to disable video autoplay that will be used mostly with maleus (our selenium-based load testing tool for testing the new bridge). Disabling video rendering lowers the resource utilisation of the selenium nodes.
Bring back the workaround introduced in afd2aea7
but removed in 21dcc41d. On conference join,
several other actions have already been fired
that try to set the large video participant
and select the participant on the bridge.
The problem is there is no conference during
these actions so the select participant
never fires. Then subsequent actions do not
fire select participant because the large
video participant has not changed.
We try to load the configuration with every room change, even when there is no
room. There is a bad (corner) case: when we have no config cached (first boot or
wiped app data). In such case the user is trapped in an infinite loop because we
require the config to show the welcome page, oh well.
Pretend we have a configuration by creating the most minimal one to at least get
to the welcome page.
Audio streams are automatically played by WebRTC and this won't change, probably
ever. There is no point in having checks and an Audio component which does
nothing.
In iOS 13 if the call is not unmuted when we report it to the system as started,
an action to unmute it is dispatched automagically. Thanks, Apple.
So, delay synchronizing the muted state until the conference is started (after
the join action). This creates a small window for de-synchronization, but it's
very short and it seems unavoidable.
This change is only applied to operating systems built by the fruit company in
Cupertino.
