From eff6ac721e6a88857d1adea05f703989f5e70839 Mon Sep 17 00:00:00 2001 From: David Smith Date: Fri, 6 Jun 2008 08:43:59 -0500 Subject: Changed/renamed utrace probes. 2008-06-06 David Smith * 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 * 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. (__stp_utrace_attach_match_tsk): Ditto. (__stp_utrace_task_finder_report_clone): Ditto. (__stp_utrace_task_finder_report_exec): Ditto. (stap_utrace_task_finder_report_death): Ditto. (stap_start_task_finder): Ditto. (stap_stop_task_finder): Added debug logic. 2008-06-06 David Smith * systemtap.base/utrace_p4.exp: Updated for utrace probe changes. * systemtap.base/utrace_p5.exp: Ditto. --- testsuite/systemtap.base/utrace_p4.exp | 27 ++++++++++++++++++--------- 1 file changed, 18 insertions(+), 9 deletions(-) (limited to 'testsuite/systemtap.base/utrace_p4.exp') diff --git a/testsuite/systemtap.base/utrace_p4.exp b/testsuite/systemtap.base/utrace_p4.exp index eb6ea685..5544ee55 100644 --- a/testsuite/systemtap.base/utrace_p4.exp +++ b/testsuite/systemtap.base/utrace_p4.exp @@ -49,11 +49,12 @@ proc stap_compile { TEST_NAME compile script args } { # Initialize variables set utrace_support_found 0 -set clone_script {"probe process(\"/bin/ls\").clone { print(\"ls clone\") }"} -set death_script {"probe process(\"/bin/ls\").death { print(\"ls death\") }"} +set begin_script {"probe process(\"/bin/ls\").begin { print(\"ls begin\") }"} +set end_script {"probe process(\"/bin/ls\").end { print(\"ls end\") }"} set syscall_script {"probe process(\"/bin/ls\").syscall { printf(\"|%d\", \$syscall) }"} set syscall_return_script {"probe process(\"/bin/ls\").syscall.return { printf(\"|%d\", \$syscall) }"} -set exec_script {"probe process(\"/bin/ls\").exec { print(\"ls exec\") }"} +set thread_begin_script {"probe process(\"/bin/ls\").thread.begin { print(\"ls thread.begin\") }"} +set thread_end_script {"probe process(\"/bin/ls\").thread.end { print(\"ls thread.end\") }"} # Try to find utrace_attach symbol in /proc/kallsyms set path "/proc/kallsyms" @@ -69,16 +70,16 @@ set TEST_NAME "UTRACE_P4_01" if {$utrace_support_found == 0} { untested "$TEST_NAME : no kernel utrace support found" } else { - # Try compiling a clone script - stap_compile $TEST_NAME 1 $clone_script + # Try compiling a begin script + stap_compile $TEST_NAME 1 $begin_script } set TEST_NAME "UTRACE_P4_02" if {$utrace_support_found == 0} { untested "$TEST_NAME : no kernel utrace support found" } else { - # Try compiling a death script - stap_compile $TEST_NAME 1 $death_script + # Try compiling a end script + stap_compile $TEST_NAME 1 $end_script } set TEST_NAME "UTRACE_P4_03" @@ -101,6 +102,14 @@ set TEST_NAME "UTRACE_P4_05" if {$utrace_support_found == 0} { untested "$TEST_NAME : no kernel utrace support found" } else { - # Try compiling an exec script - stap_compile $TEST_NAME 1 $exec_script + # Try compiling an thread.begin script + stap_compile $TEST_NAME 1 $thread_begin_script +} + +set TEST_NAME "UTRACE_P4_06" +if {$utrace_support_found == 0} { + untested "$TEST_NAME : no kernel utrace support found" +} else { + # Try compiling an thread.end script + stap_compile $TEST_NAME 1 $thread_end_script } -- cgit
