Modify the return logic such that exit code 1 is used when the initial
connection fails, but if a session is established, and then the device
disconnects, exit code 2 is emitted.

We must distinguish 3 cases for await_for_server():
 - an error occurred
 - no error occurred, the device is connected
 - no error occurred, the device is not connected (user requested to
   quit)

For this purpose, use an additional output parameter to indicate if the
device is connected (only set when no error occurs).

Hi,

Thank you for your PR.

I added a preliminary commit to report the 3 possible states in await_for_server() (this simplifies the implementation of this feature): 1f4c801

Then I made minor changes to your commit:

  • use a dedicated enum scrcpy_exit_code (to avoid exposing SDL constants resulting of implementation details)
  • (nitpick) EXIT CODESEXIT STATUS in manpage (for consistency with other manpages)

The resulting branch is here: exit_code

Please review/test :)

@rom1v I've been running scrcpy from your exit-code branch, and it works just fine. Thank you!

Do you need me to migrate your branch over to this PR or should we just close this and make a new one on the basis of your branch?

Merged into dev.

I also added a commit to document the exit statis in scrcpy --help: b1dbc30

Exit status:

      0  Normal program termination
      1  Start failure
      2  Device disconnected while running

Audio did not work on Honor devices.

Two workarounds are necessary:
 - a system context must be set as a base context of FakeContext (so
   that a PackageManager is available),
 - the same workaround as for Meizu phones must also be applied (so that
   ActivityThread.currentApplication() return a valid instance).

These workarounds must not be applied for all devices, they cause other
issues.
