Please be aware that this feature will likely require a privacy and security review.

If one of you could let me know when you have the code landed and are a few weeks out from enabling I will get the reviews started at that point.

Ofcourse Owen. I will keep you in the loop.
If somebody is interested to have a look right now, I have a first version of the code at https://codereview.chromium.org/1892083002/ . This CL is mainly for comments on the overall structure. Details will be filled up as we go.

Also it contains logic for Suspend/Resume mojo API calls based on the page visibility. For this purpose 'SensorProxy' inherits 'PageVisibilityObserver'.

[Sensors] Handle default sensor configuration

This patch provides platform sensor's default configuration to the Blink side at 'SensorProxy' initialization stage.
Default configuration will be used for sensors construction by default, e.g. 'let sensor = new AmbientLightSensor();'.

A few related changes are added as well:
- Rename 'SensorReadBuffer' to 'SensorInitParams'
- Remove repeated code calling 'startListening()' from 'Sensor::onSensorInitialized()'
- Call 'reset()' for all 'SensorProxy' members from 'SensorProxy::handleSensorError()'

[Sensors] Allow Sensor API only on secure top-level browsing contexts and add frequency checks

This patch introduces secure context and top-level browsing context checks as required at https://w3c.github.io/sensors/#construct-sensor-object.

Besides it introduces check of the given frequency option: if the given frequency is negative exception is raised; if the given frequency is more than 60 Hz it is capped to 60 Hz.

[sensors] Introduce asynchronous way to create sensors.

As long as sensors implementation on Linux/ChromeOS will
be based on reading from files (sensors' files are located
in /sys/dev/iio/devices), asynchronous way of creating
sensors is introduced with this patch.

To be more specific, the asynchronous path is needed because
sensors' existence will be checked by blocking IO methods in
case of Linux/ChromeOS and in order to be able to say
whether a sensor exists or not, asynchronous path will be
used.

In case of Android and Mac, callbacks will be
called immediately as soon as a sensor manager in Android or
IOServiceGetMatchingService in Mac returns a sensor object
or nullptr.

How it works:
As soon as a request for a new sensor is received, callbacks
are stored into a vector which is pushed into a map with a
type key and the vector itself. If no callback has been
stored before, CreateSensorInternal() method is called.
Then:
 *Linux/ChromeOS (under development): a new thread is
  created which will handle concrete sensors creation.
 *Android: when CreateSensorInternal() is called, java code
  is called and everything is handled by the sensor manager,
  which returns synchronously. Once sensor found, it is
  returned. Otherwise, nullptr is returned.
 *Mac (under development)
  https://codereview.chromium.org/2332903002/: everything
  is handled by IOServiceGetMatchingService, which returns
  synchronously.

[Sensors] Improvements in shared buffer managing

This patch adds the following improvements:
-Introduces SeqLock synchronization for shared buffer reads and writes.

- Single sensor shared buffer is guaranteed to have same fixed size on every platform. This is important as our layout tests use fixed sized shared buffer on JS side.

- Introduced common data structures for sensor reading and sensor reading buffer that are used in both blink and platform layers.

For the implementation on Android shared buffer operations moved from java to generic C++ code, same code is to be reused for implementations on other platforms.

[sensors] [mac] Implement ambient light sensor for macOS

Use IOKit to get information from the platform and callback
when the value of the sensor is changing.

Make sure to provide the time stamp as well (which is required
by the spec). The data is passed in a shared buffer using
seqlock mechanism.

The patch also moves around code in content/device_sensors
because they are needed by this implementation. This will
avoid device/ to depend on content/. The default frequency
to pull the ambient light is now inside device/sensors/public/cpp
(shared amongst platforms). The method to convert the value
returned by the LMU sensor (on mac machines) to lux is moved
to device/sensors/public/cpp) as well.

Finally the patch also add a smart pointer to handle IONotificationPortRef.
There are other opportunities in the chromium codebase to use that new smart
pointer, I will land a follow up CL.

[Sensors] Adding chrome flag to enable Generic Sensor based APIs

This change adds a flag to enable family of sensor APIs which are based on Generic Sensor API including Ambient Light Sensor API.
So far it is only available on Android and Mac OS, should become available on other platforms as soon as platform-specific implementation lands.

Generic Sensor API: https://w3c.github.io/sensors/
Ambient Light Sensor API: http://w3c.github.io/ambient-light/

Intent to Implement:

[sensors] Make generic_sensor a component

The motivation is to allow classes to be exported (for component builds) so that
a browser test can be written outside of device/ and on top
of content/ and the needed classes can be used to write a fake/mock
provider with fake/mock sensors (the test will come in follow up CL).
The motivation is to test end to end the feature in a cross platform
and non hardware dependent way and checking JavaScript behavior.

[sensors][mac] Make sure to update the sensor value when initializing the sensor.

IOServiceAddInterestNotification will only notify when the hardware sensor
value changes however when calling StartSensor we need to make
sure to query the value of the sensor right away to return the correct
value to JavaScript. The reason is that after calling StartSensor
the light conditions may never change and the IOServiceAddInterestNotification
callback will never be called and we return the default 0.0 sensor value. We
can fix this by making sure to initialize the sensor value in
PlatformSensorAmbientLightMac StartSensor.

[sensors] Add a browser test to sanity check ambient light sensor.

The idea of the test is to sanity check the entire generic sensor
integration especially to verify that the data put in the shared
buffer is correctly handled by Blink.

The patch add a way to provide a fake provider which will create
fake sensors so we have a reliable and hardware independent solution.

The rest of the testing is happening either as layout tests or
as unittests in device/generic_sensor.

[sensors] Introduce asynchronous way to create sensors.

As long as sensors implementation on Linux/ChromeOS will
be based on reading from files (sensors' files are located
in /sys/dev/iio/devices), asynchronous way of creating
sensors is introduced with this patch.

To be more specific, the asynchronous path is needed because
sensors' existence will be checked by blocking IO methods in
case of Linux/ChromeOS and in order to be able to say
whether a sensor exists or not, asynchronous path will be
used.

In case of Android and Mac, callbacks will be
called immediately as soon as a sensor manager in Android or
IOServiceGetMatchingService in Mac returns a sensor object
or nullptr.

How it works:
As soon as a request for a new sensor is received, callbacks
are stored into a vector which is pushed into a map with a
type key and the vector itself. If no callback has been
stored before, CreateSensorInternal() method is called.
Then:
 *Linux/ChromeOS (under development): a new thread is
  created which will handle concrete sensors creation.
 *Android: when CreateSensorInternal() is called, java code
  is called and everything is handled by the sensor manager,
  which returns synchronously. Once sensor found, it is
  returned. Otherwise, nullptr is returned.
 *Mac (under development)
  https://codereview.chromium.org/2332903002/: everything
  is handled by IOServiceGetMatchingService, which returns
  synchronously.

[sensors] [win] Implement ambient light sensor for Windows platform

This CL adds implementation for ambient light sensor on Windows platform
and introduces adaptation layer between Generic Sensor and Windows Sensor
APIs.

Three new classes are introduced:
* PlatformSensorProviderWin: creates PlatformSensorWin instances and manages
  sensor thread where all Windows Sensor API COM objects are running.

* PlatformSensorWin: Uses PlatformSensorReaderWin to receive notifications
  about sensor reading and state change updates. Lives on IPC thread.

* PlatformSensorReaderWin - Uses ISensor COM interface to get sensor reading
  and state change updates. Lives on sensor thread.

Unit tests are added to test new functionality.

[sensors] Close mock sensor stubs after test is finished

Before this CL, mock sensor instance was reused by all tests. This CL adds
code that closes mocked sensor stubs after each test, so that on the Blink
side, SensorProxy will reset and release resources associated with the sensor.
This allows to write layout tests that simulate different behavior for the
sensor of the same type.

[sensors] Ambient light sensor implementation for ChromeOS and Linux.

The patch introduces sensors implementation for
ChromeOS/Linux platforms using ambient light sensor. Both
platforms share the same code and require polling threads to
be used.

SensorDataIio structure is used to initialize a generic
SensorReader, which is created only when sensor read files
are found, and to create a concrete sensor, which takes
an ownership of the SensorReader.

A SensorReader must always be created on a polling thread,
which is further used by a sensor to poll data. Each new
sensor will have its own thread in order to avoid blocking of
each other.

As a temp solution to manage polling threads, which are not
passed to new sensors, a manager thread is used. It kills a
polling thread if a sensor cannot be created. In the future,
the manager thread will evolve to a manager class that will
manage finding new sensors attached to a system and notify a
provider about that. The provider will have its own cache in
order to avoid trying to find sensors each time after it
fails to find a requested sensor. Once the manager notifies
the provider about a new sensor, the provider updates its
cache and starts to process requests for that type of sensor.

[Sensors] Align sensor reading attribute implementation with the specification

This patch updates sensor reading implementation accordingly to specification [1] which says: "the reading attribute of two instances of the same Sensor interface associated with the same sensor hold the same SensorReading during a single event loop turn".

Besides, this patch also drops 'SensorReadingEvent' and 'SensorReadingEventInit' types which no longer exist in the specification.

[sensors] Reject test promise when callback throws an error

This CL improves test reports for ambient light sensor by wrapping
Sensor.on* callbacks that might throw an error. When error is thrown,
promise for async test is rejected and executed test would be marked
as 'FAIL'. Before this change, failing tests could timeout and block
consecutive test execution.

[sensors] [mac] Fix ambient light sensor not updating its value when closing the lid with a monitor connected.

Right now we use IOServiceAddInterestNotification with kIOGeneralInterest
as a way to get value changes from the AppleLMUController whenever
the ambient light condition changes.

However when closing the lid rapidly and a monitor is connected (which
prevents the computer to go to sleep) we don't receive a notification
and callback from the controller the whole way (until the lid is fully
closed). It means that the latest value received in JavaScript is not what
would be expected : as a developer point of view, lid closed = dark = 0.0
as a lux value.

The patch now listen kIOBusyInterest as well because when closing
the lid the AppleLMUController sends busy events which we can use
to fetch the value of the sensor and report it back in JavaScript.

[Sensors] Improvements in fetching reading for sensors with continuous reporting mode

If a platform sensors has continuous reporting mode its updates are not send via IPC, so there is a timer on Blink side which periodically reads the sensor data from shared buffer.

Before this change every sensor instance had its own repeating timer, however in case of multiple sensor instances it could bloat the thread task queue with unneeded requests to read the sensor data from shared buffer.

This patch introduces only one repeating timer per 'SensorProxy' (i.e. per frame) which is shared between all sensor instances of the same type.

Another consequent change is that now the 'SensorProxy' class is inherited from 'PageVisibilityObserver' (and the 'Sensor' class is not any more) which makes suspend/resume code path more efficient.

[sensors] Fix flakiness in generic sensors tests

This patch fixes flakiness for generic sensors layout tests by resetting
SensorProvider mock stub bindings at the end of the each layout test and
re-initializing it when needed in SensorProviderProxy.

Before this CL, if multiple sensor tests were executed by the same
content shell instance, Frame's mojo interface overrides were reset after
each test, yet SensorProviderProxy was not aware of it and kept using old
SensorProvider mojom proxy.

[sensors](CrOS/Linux) Implement Sensor device manager for sensors

This cl introduces a SensorDeviceManager for Linux and ChromeOS platforms.

Manager:
1) PlatformSensorProviderLinux owns a SensorDeviceManager that uses
DeviceMonitorLinux to enumerate iio devices and get removed/add udev
events. Once device is enumerated, added or removed, it is identified
and all the necessary information is put to SensorInfoLinux structure
and passed to the provider. If there is no such a device, it is added
to cache. In case of removal, manager checks if there was such a device
and updates it's cache accordingly + notifies the provider about a
removed device, which update own cache.
2) Requests: when a request for a sensor comes, it can be processed
immediately or asynchronously once service is up and running.

Reader:
1) There will be two strategies for a reader. At the moment
only polling read is supported.
2) The reader doesn't search for sensor files any more, those are passed
to it in SensorInfoLinux structure.

Unittests:
1) In order to make it possible to test the whole path, I've made
SensorDeviceManager's methods virtual, which allowed me to
mock and override them.
2) Unittests implement own udev methods that just read values from
files. If read is successful, the manager adds this type of sensor
associated with the files that have been read to it's cache and notifies
the provider.

[Sensors] Remove SensorReading interfaces

The SensorReading interface has been recently excluded from W3C Generic Sensor specification [1].
Now concrete sensor interfaces should themselves contain reading attributes.

Sensor layout and browser tests are updated accordingly.

[Sensors] Stop throwing InvalidStateError exceptions

The updated Generic Sensor specification [1] does not contain instructions for throwing 'InvalidStateError' exceptions from start() and stop() methods.
This allows for example to call stop() method on already stopped sensor object (such call will be simply ignored).

[Sensors] Error handler in Senor class should stop the platform sensor

At the moment SensorProxy is the only source of error notification for the Sensor class instances, however soon other error notification sources will turn up (e.g. permission subsystem), so we must guarantee that stopping of a Sensor due to an error is reflected on platform side.

[sensors][permission] Implement generic sensor permission checks

This CL implements a sensor provider proxy and changes
RenderFrameHostImpl to use that for forwarding sensor provider interface 
requests from renderers to the device service so that the proxy can
intercept the requests and allow or deny them based on permission
statuses.

This is the second part of adding permission guard for sensors based on
Generic Sensor Framework.
