This script connects to 'criu swrk' and asks for the version. If running from a git checkout the output would look like this: $ ./version.py Connecting to CRIU in swrk mode to check the version: RPC: Success CRIU major 2 CRIU minor 12 CRIU gitid v2.12-635-g6d3ae4d If not running from git checkout it looks like this: $ ./version.py Connecting to CRIU in swrk mode to check the version: RPC: Success CRIU major 2 CRIU minor 12 If running with a CRIU binary which does not support the VERSION command: $ ./version.py Connecting to CRIU in swrk mode to check the version: Error (cr-service.c:116): RPC error: Invalid req: Success RPC: Unexpected msg type Signed-off-by: Adrian Reber <areber@redhat.com> Signed-off-by: Andrei Vagin <avagin@virtuozzo.com>
