See the Tcl DTrace wiki page for details: + + http://wiki.tcl.tk/19923 + + This provider was written by Daniel Steffen and is currently available + by downloading and compiling the Tcl source with the --enable-dtrace + option to configure. + + Since the DTrace Tcl provider could be developed a little further, there is + a chance that it has changed slightly by the time you are reading this, + causing these scripts to either break or behave oddly. Firstly, check for + newer versions of the DTraceToolkit; if it hasn't been updated and you need + to use these scripts immediately, then updating them shouldn't take + too long. The following was the state of the provider when these scripts + were written - check for changes and update the scripts accordingly, + + provider tcl { + probe proc-entry(procname, argc, argv); + probe proc-return(procname, retcode); + probe proc-result(procname, retcode, retval, retobj); + probe proc-args(procname, args, ...); + probe cmd-entry(cmdname, argc, argv); + probe cmd-return(cmdname, retval); + probe cmd-args(procname, args, ...); + probe inst-start(instname, depth, stackobj); + probe inst-done(instname, depth, stackobj); + probe obj-create(object); + probe obj-free(object); + proobe tcl-probe(strings, ...); + }; + + Update: it looks like two new probes have recently been added to the + provider: proc-info and cmd-info. I'll need to update these scripts to + make use of these new probes. + |
