Hi! Since there was interest in still providing YCP debugger, I gave it a shot and here is a first prototype. I did not test it to actually trace a real module, but it provides the basic functionality and I need feedback what needs to be improved, possibly reporting bugs. The patch for yast2-core is attached, the packages for openSUSE 11.4 are available in my home project: home:visnov:branches:openSUSE:11.4:Update:Test Usage: 1) zypper install yast2-core-debugger 2) start YaST2 process with --debugger option: /usr/lib/YaST2/bin/y2base --debugger <YCP-client> <frontend> 3) start debugger: /usr/lib/YaST2/bin/ycp-debugger The currently supported commands: yast-dbg> help Available commands: q quit help this help s step n next c continue p <var> print variable value b <fnc> set breakpoint rb <fnc> remove breakpoint bt backtrace v <var>=<val> set variable value attach attach to current YaST process detach detach from current YaST process WARNING: if you enter non-existent/empty command, the communication will go out of sync and you have to start over! TODO: Infrastructure: - enable debugger at runtime - secure socket creation Client: - make it robust, most likely a complete rewrite is a way to go Breakpoints: - set breakpoint to filename:linenumber - list breakpoints Any feedback is welcome!
