| | | | | | | | | | | | | | | | This only happened if there was a lot of cruft in the testsuite dir since expect wasn't "draining" the output of the spawned ls command for some reason. Work around it by just using tcl file globs to match. * testsuite/systemtap.base/strftime.exp: Test with glob and file exists.

* Fix condition propagation across aliasesJosh Stone2009-06-092-0/+31
| | | | | | | | | | When an instance of an alias has a condition, that condition gets propagated to each of the locations that the alias defines. However, the copy of the location list was not a deep copy, and so all other instances of the alias would also incorrectly receive the condition. This patch makes the location list copy a little deeper, and adds a test case which demonstrates the issue.

* 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

* 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.

* 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.

* 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.
