| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous implementation was error-prone, because allowed returning empty tokens (mimiced strsep()), which is fine if there is a NULL semantic. Unfortunately SystemTap doesn't provide it in scripts and has only blank string (""), therefore testing against it was misleading. The solution is to return only non-empty tokens (mimic strtok()). * tapset/string.stp: Fix tokenize. * testsuite/systemtap.string/tokenize.stp: Improve and add case with more than one delimiter in the delim string. * testsuite/systemtap.string/tokenize.exp: Ditto. * stapfuncs.3stap.in: Update tokenize description. * doc/langref.tex: Ditto.

| | | | | | | | | | | | | | | | | | | | | | | | | | The original logic was a little confused. It could end up searching the separate debuginfo twice instead of falling back to the main elf file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The testcase now uses noinline, an empty asm statement and a volatile variable to prevent the function getting inlined, being totally unrolled or the recursive call being replaced with an inner-iteration. This does defeat part of the testcase though, which was testing unwinding through an optimized recursive function. But it seems the best we can do. * testsuite/systemtap.exelib/exelib.exp: Add -O3 to the mix. * testsuite/systemtap.exelib/uprobes_exe.c: Use volatile bar and mark main_func noinline. * testsuite/systemtap.exelib/uprobes_lib.c: Use volatile foo and mark lib_func noinline.

| * | PR10260: Clean up all resources after init errorsJosh Stone2009-06-101-0/+8
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | When anything in systemtap_module_init fails, and we return non-zero, then the module load is aborted. The normal module unload path (systemtap_module_exit) is not even attempted, so we need to make sure that all partially-allocated resources are returned. Our timer callbacks for the gettimeofday subsystem are a classic example of this error. If we don't unregister the timers before aborting init, they will later be called and cause a kernel fault. We also were neglecting to free the percpu context. A memory leak is less harmful, but that's fixed now too.
| * Fix condition propagation across aliasesJosh Stone2009-06-093-5/+40
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | The result of sdt's private @cast expansion was not being used, and it's not really needed anyway. The global cast visitor is registered to run as a post-processing step on ALL functions and probes, and so it will pick up and expand sdt's casts too.
