If the desktop picker window is closed before we load the sources, a JS error is thrown. From there the app goes into a broken state where when the screen sharing button is pressed nothing happens. Explanation:
When the error from the _onCloseModal handler is thrown we don't reach the line to call the onSourceChoose callback. The result is that we never call the callback received by setDisplayMediaRequestHandler. It seems that when this happens on subsequent gDM calls electron won't call the setDisplayMediaRequestHandler and therefore we don't display the desktop picker.
In order to use gDM in Electron the flow is somewhat reversed. It starts
from the Electron main process, so we need an API in the external_api
that can trigger the builtin picker. The picker is still necessary.
For the most part the changes are taking the "static propTypes" declaration off
of components and declaring them as Flow types. Sometimes to support flow some
method signatures had to be added. There are some exceptions in which more had
to be done to tame the beast:
- AbstractVideoTrack: put in additional truthy checks for videoTrack.
- Video: add truthy checks for the _videoElement ref.
- shouldRenderVideoTrack function: Some component could pass null for the
videoTrack argument and Flow wanted that called out explicitly.
- DisplayName: Add a truthy check for the input ref before acting on it.
- NumbersList: Move array checks inline for Flow to comprehend array methods
could be called. Add type checks in the Object.entries loop as the value is
assumed to be a mixed type by Flow.
- AbstractToolbarButton: add additional truthy check for passed in type.
There are (at least) two changes that are breaking:
- defaultTab is gone
- The re-rendering logic looks to have been re-written so that
passing in a new array of tabs causes a re-render, which can
reset the currently selected tab.
The fixes involved removing defaultTab from each tab configuration,
as it is no longer respected anyway. Also, instead of letting Tabs
be uncontrolled and allowing it to set its own selected, which
would result in the first tab automatically being selected on
Tabs re-render, use Tabs a controlled prop to dicate which
tab is selected; this is accomplished by specifying a selected
prop.
ESLint 4.8.0 discovers a lot of error related to formatting. While I
tried to fix as many of them as possible, a portion of them actually go
against our coding style. In such a case, I've disabled the indent rule
which effectively leaves it as it was before ESLint 4.8.0.
Additionally, remove jshint because it's becoming a nuisance with its
lack of understanding of ES2015+.
