When a test binary runs for too long, the go command sends it a SIGQUIT to force a backtrace dump. On Android, the exec wrapper will instead receive the signal and dump its backtrace. Forward SIGQUIT signals from the wrapper to the wrapped process to gain useful backtraces. Inspired by issuse 25519; this CL would have revealed the hanging test directly in the builder log.

Android ======= For details on developing Go for Android, see the documentation in the mobile subrepository: https://github.com/golang/mobile To run the standard library tests, see androidtest.bash. Run it as CC_FOR_TARGET=$STANDALONE_NDK_PATH/bin/clang GOARCH=arm64 ./androidtest.bash To create a standalone android NDK tool chain, follow the instructions on https://developer.android.com/ndk/guides/standalone_toolchain To run tests on the Android device, add the bin directory to PATH so the go tool can find the go_android_$GOARCH_exec wrapper generated by androidtest.bash. Then, use the same GOARCH as when androidtest.bash ran and set GOOS to android. For example, to run the go1 benchmarks export PATH=$GOROOT/bin:$PATH cd $GOROOT/test/bench/go1/ GOOS=android GOARCH=arm64 go test -bench=. -count=N -timeout=T
