* Better sdt.exp test cleanup.David Smith2009-06-011-1/+2
| | | | * testsuite/systemtap.base/sdt.exp: Better cleanup.

* PR10190: Suppress warnings for optional kprobesJosh Stone2009-05-221-1/+14
| | | | | | When a kernel.function or kprobe.function fails in registration, we usually print a WARNING and move on. With this patch, kprobes that have the optional '?' flag will not print any WARNING.
* PR10177: init/kill time in sleepy context onlyJosh Stone2009-05-201-29/+0
| | | | | | | | | | | | Previously, _stp_init_time and _stp_kill_time were being called from begin/end/error probes, which will run with preemption disabled. The BUG reported on RT kernels showed that cpufreq_unregister_notifier can end up sleeping, which violates our preemption block. This patch moves the init/kill into systemtap_module_init/exit, where it is safe to sleep. The code maintains a new predicate with the define STAP_NEED_GETTIMEOFDAY, so we don't still incur any timer overhead if it's not used.
* PR10091 fixes.David Smith2009-05-181-30/+141
| | | | | | | | * runtime/itrace.c (usr_itrace_report_signal): Add a workaround for ppc-specific problem. * testsuite/systemtap.base/itrace.exp: Improved tests. Improved test completeness. Will also no longer give fails for systems that don't support single or block step (will give xfails instead).
* flightrec3.exp uses cpus as array, so rename skipped.exp cpus var to nr_cpus.Mark Wielaard2009-05-151-3/+3
| | | | | | | Works around a make installcheck issue that resulted in skipped.exp failing because of "ERROR: can't set "cpus": variable is array" * testsuite/systemtap.base/skipped.exp: Renamed cpus variable to nr_cpus.
* Set explicit longer, 60 second, timeout for alternatives.exp.Mark Wielaard2009-05-151-2/+3
| | | | | | | | In an make installcheck run this is the first script that goes through the full kernel debuginfo which might take a bit. * testsuite/systemtap.base/alternatives.exp: Set timeout to 60, verbose log EOF or TIMEOUT when they occur.

* PR10102: tolerate the failure related to optional probeWenji Huang2009-05-051-1/+9
| | | | | | | | | This patch will make stap silently accept the failure related to optional probe. It puts try/catch around find_and_build which can cover most probe types. The specific treatment for dwarf_derived_probe in commit ed82b7c902d6a2e26452ec51c9cdb9665dbf9e97 is reverted.
* Revert "Fix kprobes.exp."Ananth N Mavinakayanahalli2009-05-051-6/+1

* Fix kprobes.exp.Ananth N Mavinakayanahalli2009-05-041-1/+6
| | | | Patch from Prerna Saxena.
* Fix funtion -> function typo in alternatives.exp.Mark Wielaard2009-05-021-1/+1
| | | | * testsuite/systemtap.base/alternatives.exp (local1_script): Fix typo.
* PR10007: Avoid probing syscall entry points in the testsuite.Ananth N Mavinakayanahalli2009-04-306-20/+20
| | | | While there, fix minor issues with the s390x syscall tapset.
* Use sockaddr instead of timeval in @cast testJosh Stone2009-04-292-11/+15
| | | | | | | | Using timeval had problems on big-endian multi-arch platforms (ppc64), because the user tv_sec used in the @cast didn't match the kernel tv_sec used to provide a pointer. Hopefully reading from a sockaddr should be more robust, as that type doesn't appear to need any compat wrappers for multi-archs.
* PR 6930: fix flightrec2.exp to handle filesize correctlyMasami Hiramatsu2009-04-282-11/+10
| | | | | | | * testsuite/systemtap.base/flightrec2.exp: Use stat instead of ls for checking file size. * testsuite/systemtap.base/flightrec2.stp: Increase timer interval for some architecture on which the minimum interval is more than 1 ms (e.g. xen)
* PR10102: tolerate mismatched optional probeWenji Huang2009-04-272-0/+15
| | | | | | * elaborate.cxx: Early return for mismatched optional probe. * testsuite/systemtap.base/optionalprobe.exp: New test case. * testsuite/systemtap.base/optionalprobe.stp: Ditto.
* Don't terminate when a dwarfless kprobe failsJosh Stone2009-04-241-9/+23
| | | | | | | | | | All of our other kprobe types will let the script continue after a registration failure, as per PR6749. The dwarfless kprobes should be no exception. Also, the way they were exiting was causing an unclean shutdown, so I added tests to badkprobe.exp to make sure that cleanup is always allowed to run.
* Tweak kprobes test caseWenji Huang2009-04-232-1/+6

| | | | * testsuite/systemtap.base/strftime.exp: New test case for strftime.
* PR 6930: Add testcases for on-file flight recorderMasami Hiramatsu2009-04-223-0/+117
| | | | | | * testsuite/systemtap.base/flightrec1.exp: New test case for background mode. * testsuite/systemtap.base/flightrec2.exp: New test case for file switching. * testsuite/systemtap.base/flightrec2.stp: Test script for file switching.
* Refine the @cast-with-header syntaxJosh Stone2009-04-211-2/+2
| | | | | | | The special syntax to generate a module for type information is now: - "kernel<path/to/header.h>" to use the kernel's build environment - "<path/to/header.h>" to use no special build environment, and so use gcc's default parameters only (for user mode).
* Set MAXSTRINGLEN to 133 for uprobes_ustack.exp test on 64 bit.Mark Wielaard2009-04-211-1/+4
| | | | | | | | Needs extra space since on 64bit the last ubacktrace string is 7 entries * (16 hex + 2 for 0x + 1 space) = 133 chars. Default MAXSTRINGLEN is 128 chars. * testsuite/systemtap.base/uprobes_ustack.exp: Add -DMAXSTRINGLEN.

(utrace_var_expanding_visitor::visit_target_symbol_context): In a syscall.return probe, you can't access $syscall. So use visit_target_symbol_cached() to cache the value for use here. * testsuite/systemtap.base/utrace_syscall_args.stp: Test use of $syscall in syscall.return probes.
