| | * Move testcase itrace3's warning into expectJosh Stone2009-04-011-1/+1
| | | | | | | | | | | | | | | | | | As it was, the ATTENTION was causing expect mismatches even when the test worked fine. The warning is served just as well from the expect script before starting the test.
| | * Add insn.block testcase to itrace.exp in testsuiteMaynard Johnson2009-04-011-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier today, I posted a runtime patch for the insn.block probe point. Once that patch is committed, the insn.block probe can be safely tested on any architecture. The attached patch adds such a testcase to the testsuite. Regards, -Maynard
| | * Fix for insn probe: Call arch_has_*_step() prior to calling utrace_controlMaynard Johnson2009-04-011-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The attached patch is version 2 for the problem I reported earlier today. Frank, is this more what you had in mind? With this patch, there's no need for the user to look at the system log. Error messages are sent to stderr: ERROR: insn probe init: arch does not support block step mode ERROR: probe process("/test").function("doit1@/test.c:22").return registration error (rc -1) -Maynard

| | * Fix runtime/itrace.c to call arch_has_*_step() prior to calling utrace_controlMaynard Johnson2009-04-011-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As Roland pointed out in his Mar 31 reply to a posting of mine (subject: Re: Testing insn.block probe point uncovers possible utrace bug), utrace_control() documents that the caller must ensure that arch_has_single_step and arch_has_block_step are defined before trying to use those step modes. The attached patch addresses that issue. I've tested this patch on x86_64 arch, and a block step test runs successfully, since block step is supported on that arch. Testing on ppc64 arch, the test fails as expected (since block step is not supported on ppc64 yet) with: "ERROR: callback for <pid> failed: 1" which is sent to stdderr and "usr_itrace_init: arch does not support block step mode" which is sent to the system log. This isn't the most user-friendly way of surfacing an error. Perhaps the stap runtime could have a set of defined return codes that would be mapped to strings so the user can get an idea of what the error is without looking in the system log. But that's a side issue, of course. Regards, -Maynard
| | * PR10016: Purge stap of all pgrp and system() usageJosh Stone2009-04-014-81/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We hereby no longer try to manipulate process groups in any way. We don't set a private process group, and we never kill() our entire group either. Instead of using system(), we now have a stap_system() which saves the child PID, so when we get a terminating signal we can pass it along to the child. Signals sent through the TTY have always worked, since the TTY sends it to the entire pgrp. However, if we're running as part of a wrapper script or GUI, which may not have a separate process group for stap, we still would like to allow "kill -TERM $STAPPID" to terminate stap nicely. There's still a short window of failure in the time that staprun is active, because we can't kill a setuid process from a user process. Once staprun drops privileges and execs to stapio though, everything should work fine.
