| | |/ | | | | | | | | | | | | | | | | | | * doc/langref.tex (section{Components of a SystemTap script}): Use .call/.return for the example of tracing function entry/exit. Also mention "-l" for listing probeable functions. (subsection{Embedded C functions}): Close the examples with '%}'.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The saved stdout should have the exact name of the generated module, which is better than using a recursive find to locate it. Tracepoints and @cast may generate additional .ko's which we don't want to confuse with the real deal. * stap-server (create_response): grep stdout for the module name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot of time during the installcheck was spend just sleeping. Reduce the sleep time by at least one fifth. * testsuite/systemtap.examples/*/*meta: Reduct -c "sleep" time.
| | | | * Make tracepoints.exp test more efficient by running as one giant script.Mark Wielaard2009-09-131-6/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there are lots of tracepoints in the kernel running a script for each one individually can take several minutes. So run them all in one giant script at the same time. Also increase timeout for the stap -l collection step since with an empty cache that might take more than the default 10 seconds. * testsuite/systemtap.base/tracepoints.exp: Increase default timeout. Collect all script fragments and run them as one.
| | | | * Only test highest optimization for exelib.exp test.Mark Wielaard2009-09-131-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is not much to gain from testing low and high optimized programs. So only test highest optimization level. Half test time from 200 to 100 sec. * testsuite/systemtap.exelib/exelib.exp: Set opt to list containing just -O3.
| | | | * Replace small exelib.exp testcases with one jumbo testcase.Mark Wielaard2009-09-133-1/+181
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge lib, mark, uname and ustack stp and tcl scripts into one large libmarkunamestack stp and tcl script. But keep the individual tests in case the large test fails and one wants to debug the individual steps. Takes test time for exelib.exp down from 700 seconds to 200 seconds. * testsuite/systemtap.exelib/libmarkunamestack.stp: New large stp script. * testsuite/systemtap.exelib/libmarkunamestack.tcl: New large tcl script. * testsuite/systemtap.exelib/exelib.exp: Use libmarkunamestack.
| | | | * Remove duplicate uprobe_derived_probe codeJosh Stone2009-09-111-219/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Much of uprobe_derived_probe is a straight copy of dwarf_derived_probe, and some of the comments even acknowledge this. I'm instead making this an inheritance, so the duplication can be chopped away. * tapsets.cxx (struct dwarf_derived_probe): Reorganize for inheritance. (dwarf_derived_probe::dwarf_derived_probe): Adapt to handle process. (struct uprobe_derived_probe): Inherit from dwarf_derived_probe and remove duplicate members and methods. (uprobe_derived_probe::emit_module_decls): Member name changes.

| | | | | * PR10594 cont'd: Use parent die cache for variable lookupJosh Stone2009-09-103-73/+158
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Variable lookup is usually done through the scopes from dwarf_getscopes at a particular pc. This requires an expensive traversal to find the inner-most die containing the pc. For cases where that containing die is known, e.g. at a particular function entry, we can do much better with our die_parent_cache. This may also help get more accurate variable scopes in cases where multiple dies contain a pc and the innermost isn't what we're trying to probe. For example, an inlined call chain of foo->bar->baz may all have the same entry pc, but if the probe was on function("bar"), we would want the variables in bar's scope, not baz's. * dwflpp.h (struct dwflpp): Remove pc_cached_scopes, num_cached_scopes, and cached_scopes, as they are now remembered by the caller. * dwflpp.cxx (dwflpp::getscopes): New - the DIE version uses the parent cache, and the pc version just defers to dwarf_getscopes. (dwflpp::print_locals, literal_stmt_for_local): Take a scopes vector. (dwflpp::find_variable_and_frame_base): Take a scopes vector from the caller instead of computing it every time. (dwflpp::dwarf_getscopes_cached): Removed. * tapsets.cxx (dwarf_var_expanding_visitor::getscopes): New cached lookup function which gets the scopes from the DIE if possible. (dwarf_var_expanding_visitor::visit_target_symbol): Call getscopes.

(dwflpp::cache_die_parents): New function to build the parent cache. (dwflpp::~dwflpp): Clean up the parent caches. (dwflpp::iterate_over_labels): Use the cached getscopes_die. (dwflpp::find_variable_and_frame_base): Ditto. * tapsets.cxx (dwarf_derived_probe::saveargs): Ditto. (uprobe_derived_probe::saveargs): Ditto. (dwarf_var_expanding_visitor::visit_target_symbol_context): Ditto.

However, the probe point for this synthetic probe was copied naively, so that several problems could occur: - if the original probe point contained wildcards, then each synthetic one also did, and was therefore multiply derived later - if the probe point referred to a multiply instantiated function, the synthetic one was not directly identified with it (at the dwarf_addr level) Now the synthetic probe is created more carefully, bypassing any further derivation/expansion processing steps. * tapsets.cxx (dwarf_var_expanding_visitor): Change add_probe to add_call_probe field. (visit_target_symbol_saved_return): Store only the body of the synthetic probe. (dwarf_derived_probe ctor): Create intimately related dwarf_derived_probe for synthetic probe.

However, open_oldoutfile and open_relayfs_files open files with fopen and set only percpu_tmpfile. This will cause a problem with -S option, that out_fd will be closed when the file size reaches fsize_max and new fd will be opened only on percpu_tmpfile. So, out_fd should be synchronized with percpu_tmpfile. * runtime/staprun/relay_old.c (open_oldoutfile): Set fd of output file to out_fd[cpu]. (open_relayfs_files): Ditto.
