Romain Vimont b49f4e795e Add missing error handling 
If "adb get-serialno" fails, attempting to read from the uninitialized
pipe is incorrect.
 2021-11-17 21:59:19 +01:00
Romain Vimont 3eb8202adf Configure init and cleanup asynchronously 
Accessing the settings (like --show-touches) on start should not delay
screen mirroring.
 2021-11-17 20:09:22 +01:00
Romain Vimont 83f66ea06c Do not quit on cleanup configuration failure 
Cleanup is used for some options like --show-touches to restore the
state on exit.

If the configuration fails, do not crash the whole process. Just log an
error.

Romain Vimont d8358ce857 Read/write settings via command on Android >= 12 
Before Android 8, executing the "settings" command from a shell was
very slow (~1 second), because it spawned a new app_process to execute
Java code. Therefore, to access settings without performance issues,
scrcpy used private APIs to read from and write to settings.

However, since Android 12, this is not possible anymore, due to
permissions changes.

To make it work again, execute the "settings" command on Android 12 (or
on previous version if the other method failed). This method is faster
than before Android 8 (~100ms).

Romain Vimont 4bc5baeeb5 Add throwable parameter to Log.w() 
When an exception occurs, we might want to log a warning instead of an
error.
 2021-11-17 19:59:43 +01:00
Romain Vimont 0672f7e405 Report settings errors via Exceptions 
Settings read/write errors were silently ignored. Report them via a
SettingsException so that the caller can handle them.

This allows to log a proper error message, and will also allow to
fallback to a different settings method in case of failure.
 2021-11-17 19:59:27 +01:00
Romain Vimont 6d6a436563 Wrap settings management into a Settings class 
Until now, the code that needed to read/write the Android settings had
to explicitly open and close a ContentProvider.

Wrap these details into a Settings class.

This paves the way to provide an alternative implementation of settings
read/write for Android >= 12.

Romain Vimont 9cb14b5166 Inherit only specific handles on Windows 
To be able to communicate with a child process via stdin, stdout and
stderr, the CreateProcess() parameter bInheritHandles must be set to
TRUE. But this causes *all* handles to be inherited, including sockets.

As a result, the server socket was inherited by the process running adb
to execute the server on the device, so it could not be closed properly,
causing other scrcpy instances to fail.

To fix the issue, use an extended API to explicitly set the HANDLEs to
inherit:

Romain Vimont ac23bec144 Expose socket interruption 
On Linux, socket functions are unblocked by shutdown(), but on Windows
they are unblocked by closesocket().

Expose net_interrupt() and net_close() to abstract these differences:
 - net_interrupt() calls shutdown() on Linux and closesocket() on
   Windows (if not already called);
 - net_close() calls close() on Linux and closesocket() on Windows (if
   not already called).

This simplifies the server code, and prevents a data race on close
(reported by TSAN) on Linux (but does not fix it on Windows):

Romain Vimont 5222f213f4 Update FAQ to mention HID keyboard 2021-10-26 21:30:04 +02:00
Romain Vimont e4163321f0 Delay HID events on Ctrl+v 
When Ctrl+v is pressed, a control is sent to the device to set the
device clipboard before injecting Ctrl+v.

With the InputManager method, it is guaranteed that the device
synchronization is executed before handling Ctrl+v, since the commands
are executed on the device in sequence.

However, HID are injected from the computer, so there is no such
guarantee. As a consequence, on Android, Ctrl+v triggers a paste with
the old clipboard content.

To workaround the issue, wait a bit (2 milliseconds) from the AOA
thread before injecting the event, to leave enough time for the
clipboard to be set before injecting Ctrl+v.
 2021-10-26 21:30:04 +02:00
Romain Vimont c96874b257 Synchronize HID keyboard state on first event
