afb-debug: add features for debugging
When compiled with -DAGL_DEVEL or -DAFB_INSERT_DEBUG_FEATURES afb-daemon interprets the environment variables AFB_DEBUG_BREAK and AFB_DEBUG_WAIT. The environment variable AFB_DEBUG_BREAK make afb-daemon emit a break (SIGINT) that should be treated by the debugger. The environment variable AFB_DEBUG_WAIT make afb-daemon wait for a break (SIGINT) to continue. This can be used to attach a debugger. The content of the variables AFB_DEBUG_BREAK and AFB_DEBUG_WAIT is a list of key names of the point where the action should occur. The list is separated by spaces or commas ','. Example: AFB_DEBUG_WAIT=main-entry,start-load The defined points are: main-entry, main-args, main-start, start-entry, start-load, start-start, start-http, start-call, start-exec. Here some of their characteristic: - main-entry: at the beginning befaore any other instruction - main-args: after parsing arguments - main-start: after daemonisation before starting - start-entry: at start entry - start-load: before loading bindings after initialisation of afb-daemon - start-start: after loading bindings befaore starting it - start-call: after init before starting HTTP server - start-http: after http server, before calling startup calls - start-exec: before running the --exec command Change-Id: Id405e749c590fb95f32e30a7d37c30b6412cf0a5 Signed-off-by: José Bollo <jose.bollo@iot.bzh>
