ios-device-agent

• There was memory leak in DoguScreen that broadcast screen buffer. Constantly reconnecting tcp connection( {"type":"livecheck"}) makes memoryleak. I don't know why but I detected it with Instruments > Activity Monitor, the memory of DoguScreen was about 7 Mib buf after 20 minutes, It reaches 9 Mib and in this time, go-device-controller's new tcpclient can't read screen buffer with "EOF" error

  • The Livecheck session changed to keep tcp connection
  • Check go-device-controller's surface status in ios-device-agent, and if there is problem in surface, restart ios-device-agent

• Does memoryleak fixed?

  • I can't guarantee it 100%, but I confirmed that it maintained 7.14 Mib when turned on for about 4 hours.

I will merge it first to check if there are any problems when running it continuously after deployment.
