| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2008-06-06 David Smith <dsmith@redhat.com> * tapsets.cxx (enum utrace_derived_probe_flags): Redefined in terms of probe types instead of utrace events. (utrace_var_expanding_copy_visitor::visit_target_symbol): Uses new utrace_derived_probes_flags values. (utrace_builder::build): Handles new probe types and new utrace_derived_probes_flags values. (utrace_derived_probe_group::emit_probe_decl): Updated to handle new utrace_derived_probe_flags values. (utrace_derived_probe_group::emit_module_decls): Ditto. Also correctly handles 'begin' events correctly by installing a quiesce handler (instead of running the probe directly). (register_standard_tapsets): Registers updated utrace probe types. 2008-06-06 David Smith <dsmith@redhat.com> * task_finder.c: Added some debug logic. Use '-DDEBUG_TASK_FINDER' to enable. (stap_utrace_attach): Renamed from '__stp_utrace_attach'. (__stp_utrace_attach_match_filename): Calls callback with notification that this is a process or thread event.

| | | | | | | | 2008-06-03 David Smith <dsmith@redhat.com> * tapsets.cxx: Added several string tokens that are used instead of hard-coded strings. (register_standard_tapsets): Uses new string tokens.

| | | | | | | | | | | | | | | | | | | | | | | 2008-05-28 David Smith <dsmith@redhat.com> * tapsets.cxx (utrace_derived_probe_group::emit_probe_decl): Instead of adding clone handlers, just call the probes directly. (utrace_derived_probe_group::emit_module_decls): For syscall probes, on exec detach the parent's utrace engine from the child. 2008-05-28 David Smith <dsmith@redhat.com> * task_finder.c (__stp_utrace_attach_match_filename): Added register_p parameter, which is passed on to the callback. Only adds death notification if register_p is 1. If register_p is 0, removes death notification. (__stp_utrace_attach_match_tsk): Moved code from __stp_utrace_task_finder_report_clone that handles the details of grabbing a task's path. (__stp_utrace_task_finder_report_clone): Calls new __stp_utrace_attach_match_tsk(). (__stp_utrace_task_finder_report_exec): Notifies upper layer that it might need to detach from newly exec'ed process.`
* Minor improvement to multi-threaded support.David Smith2008-05-281-2/+5
| | | | | | | | | | | | | | | | | | | 2008-05-21 David Smith <dsmith@redhat.com> * tapsets.cxx (utrace_derived_probe_group::emit_module_decls): Added new 'event_flag' parameter to task_finder callback. Only calls probe handlers if we received the correct event. 2008-05-21 David Smith <dsmith@redhat.com> * task_finder.c (__stp_utrace_attach_match_filename): Added event_flag parameter of event to pass to callback. (__stp_utrace_task_finder_target_death): Ditto. (__stp_utrace_task_finder_report_clone): Calls __stp_utrace_attach_match_filename() with new argument. (__stp_utrace_task_finder_report_exec): Ditto. (stap_start_task_finder): Calls callback with an invalid event_flag since this callback call isn't related to an event.
