Hi Alex,

Tried your suggestions to copy and run in rust.py without any issue as below.
===============================
builddir = get_bb_var("B", "rust-testsuite")
ssh = SSHControl(ip=qemu.ip, logfile=qemu.sshlog, user="root", timeout=600)
ssh.copy_to(builddir + "/" +
"build/x86_64-unknown-linux-gnu/stage2-tools-bin/remote-test-server","~/")
t_thread = threading.Thread(target=ssh.run,
args=("~/remote-test-server -v remote",))
t_thread.start()
===============================

If we set "TEST_DEVICE_ADDR" in rust.py through "runCmd" as shown
below,  the remote-test-client does not connect  to the image.
So a lot of tests fail.
===============================
"cmd  = "export TEST_DEVICE_ADDR=%s:12345;" % qemu.ip"
runCmd(cmd)
bitbake("{} -c check".format(recipe))
===============================

Also, I tried to move do_check content to rust.py without any success.
===============================
cmd = "export PATH=%s/../recipe-sysroot-native/usr/lib/rustlib/:" % builddir
cmd= cmd + "%s/../recipe-sysroot-native/usr/bin:$PATH;" % builddir
cmd = cmd + "export
RUST_TARGET_PATH=%s/../recipe-sysroot-native/usr/lib/rustlib/;" %
builddir
cmd = cmd + "cd " + builddir + ";"
cmd  = "export TEST_DEVICE_ADDR=\"%s:12345\";" % qemu.ip
cmd = cmd + "python3 src/bootstrap/bootstrap.py -j 40 --verbose test
--no-fail-fast --bless --target aarch64-poky-linux > summary.txt 2>&1"

Error:
File "/ala-lpggp31/vinay/review-2/poky-contrib/meta/lib/oeqa/utils/commands.py",
line 210, in runCmd
raise AssertionError("Command '%s' returned non-zero exit status
%d:\n%s" % (command, result.status, exc_output))
AssertionError: Command 'export
TEST_DEVICE_ADDR="192.168.7.2:12345";python3
src/bootstrap/bootstrap.py -j 40 --verbose test --no-fail-fast --bless
--target aarch64-poky-linux > summary.txt 2>&1' returned non-zero exit
status 2:
===============================

So in rust.py only copy and execution of "remote-test-server" is taken care of.
And the test execution is by  do_check of rust-testsuite.inc as below,
===============================
do_check () {
    export TEST_DEVICE_ADDR="192.168.7.2:12345"
    rust_runx test --no-fail-fast --bless --target "${TARGET_SYS}" >
summary.txt 2> /dev/null
}

Let me know if this ok. will send patches with changes for review.

Regards,
Vinay

Hi Alex,

Tried testing outside oe-selftest framework, it works fine without any errors,

export TEST_DEVICE_ADDR="192.168.7.4:12345"
rust_runx test --no-fail-fast --bless --target "aarch64-poky-linux" >
summary.txt 2> /dev/null

Also, log (summary.txt) shows "remote-test-client" is connecting to
the image without any issue.

Will integrate these changes in oe-selftest and let you know.

Checking suggestions, the booted image with tap seems to be working by
passing "-monitor  telnet:127.0.0.1:1234,server,nowait"
so I will execute testing and update you.

Thanks, can you please look into the error? The line where it happens and the way to get a backtrace is right there :)
There's no reason it shouldn't work.

Hi Alex,

Error on qemu  image (ex. Aarch64) booted with tap interface.

"remote-test-server" on qemu-image with a tap interface throws an error.
The emulators for rust testing are with tcp port forwarding so used
slirp method with added rust port.

I'm not sure I understand - what kind of error? In both cases the server starts listening on a port, so in slirp scenario the address is 127.0.0.1:12345 (prone to breakage if something else on the build host took that port btw, including another instance of the same test), in tap it would be 192.168.7.2:12345. For the client you simply supply that via TEST_DEVICE_ADDR. No?
