* Signal-based file switching support for relay/ring buffer.Masami Hiramatsu2009-09-163-22/+97
| | | | | | | | | | * runtime/staprun/relay.c (switch_outfile): New function for file switching. (reader_thread): Don't assign empty_handler to SIGUSR2, and switch output file when receiving signal(SIGUSR2) on ppoll. (switchfile_handler): Send SIGUSR2 signal to reader threads for file switching. (init_relayfs): Assign switchfile_handler to SIGUSR2. * staprun.1.in: Add FILE SWITCHING BY SIGNAL section.

| * Make labels -l .label test independent of list output order.Mark Wielaard2009-09-161-2/+9
| | | | | | | | | | * testsuite/systemtap.base/labels.exp (-l .label): List all output lines individually in expect regex.
| * Clean up dwflpp::translate_location workaround for DW_AT_data_member_location.Mark Wielaard2009-09-163-53/+11
| | | | | | | | | | | | | | | | | | | | | | Do the same workaround as loc2c-test.c does. Just treat a constant member location offset as a DW_OP_plus_uconst and call c_translate_location for it. Also Remove c_translate_add_offset. * dwflpp.cxx (dwflpp::translate_location): Check elfutils version and only do workaround for elfutils < 0.142. * loc2c.h (c_translate_add_offset): Removed. * loc2c.c (c_translate_add_offset): Likewise.
| * Clean up loc2c-test workaround for constant DW_AT_data_member_location.Roland McGrath2009-09-161-27/+17
| | | | | | | | | | | | * loc2c-test.c (handle_variable): Skip the workaround for elfutils 0.142. When doing it, use a synthetic location expression. Never use c_translate_add_offset, which is broken.
| * Remove function comparison from label iterationJosh Stone2009-09-153-33/+37
| | | | | | | | | | | | | | | | | | | | | | We already have filtered functions and inlines, so just iterate in each of those to look for labels. * dwflpp.cxx (dwflpp::iterate_over_labels): Assume that the die we're looking at is already a matching function, and don't descend into inlined functions in this body. * tapsets.cxx (query_srcfile_label): Iterate through inlines too. (query_cu): Iterate over functions and inlines instead of the CU.

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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.
