* Relax the type-matching in the cmd_parse13 testJosh Stone2009-07-301-1/+1
| | | | | Dwarf probes are now printing their $target variables in -L, so we need to handle more than just stap types in the regular expression.

* PR10427 Multiple tracepoints OK!Mark Wielaard2009-07-221-1/+3
| | | | | * testsuite/systemtap.base/tracepoints.stp: Only print once, when enough hits, or at the begin probe.
* Use the query paradigm for resolving sdt probesJosh Stone2009-07-212-377/+384
| | | | | | | | | | | | | | | | There was a bad assumption in the probe_table initialization that the dwflpp->module would be immediately valid. We should not assume that dwflpp only has one module, or that any module is necessarily in focus. Instead, I've created an sdt_query class which will call an iterate_over_modules like the other dwarf probe types. For now this means just a single module, but it will also open the door to iterating over all linked libraries too, for example. * dwflpp.cxx (dwflpp::setup_user): don't "save mod!" anymore * tapsets.cxx (probe_table -> sdt_query): convert to a query-style class, and also take over the task of iterating over the probes. (dwarf_builder::build): leave the iteration to sdt_query
* Remove unused 'sess' from dwarf_query ctorJosh Stone2009-07-211-6/+4

| | | | systemtap.spec (post,preun): Call rmmod uprobes.
* Save module when dwflpp setup_user.Mark Wielaard2009-07-211-0/+1
| | | | * dwflpp.cxx (setup_user): Set module to mod.
* PR10424: Consider each tracepoint header separatelyJosh Stone2009-07-205-52/+83
| | | | | | | | | | | | | | | | With the current monolithic tracepoint query module, a failure in any of the discovered tracepoint headers means that you can't use any of the others either. This patch creates a separate query module for each header so they can pass or fail independently. * buildrun.cxx (make_tracequery): take a single header name instead of globbing for everything we can find. * hash.cxx (find_tracequery_hash): name the header file we're hashing. * tapsets.cxx (tracepoint_query::handle_query_func): make sure we don't duplicate tracepoints found through different headers. (tracepoint_builder::get_tracequery_module): get a header's module (tracepoint_builder::init_dw): glob for all tracepoint headers, and feed all their modules into dwflpp.
* Make sure that non-existent files still affect hashingJosh Stone2009-07-201-6/+6
| | | | | | | The fact that a file _doesn't_ exist is significant, so adding such a file to a computed hash should still influence the output. * hash.cxx (hash::add_file): add bogus stat info for non-existent files
* Allow dwflpp to take a vector of module namesJosh Stone2009-07-202-21/+38
| | | | | | | | | This will be used to load tracepoint modules as a bunch of little query modules into a single dwflpp. * dwflpp.cxx (setup_user): take a vector instead of a single module (dwflpp::dwflpp): form a vector in the singular case, and add a variant that takes and passes through a vector of modules.
* Return hash module values directly as stringsJosh Stone2009-07-204-20/+19
| | | | | | | | * session.h (systemtap_session): remove tracequery_path * hash.cxx (find_tracequery_hash, find_typequery_hash): return strings * tapsets.cxx (dwarf_cast_expanding_visitor::filter_special_modules): get the hashed path from the return value instead of a parameter (tracepoint_builder::init_dw): ditto, and don't stuff it in session

* Fixed PR 10386 by removing the need to convert a pid to a task.David Smith2009-07-204-18/+6
| | | | | | | | | * runtime/itrace.c (usr_itrace_init): Changed prototype to take a task_struct instead of a pid. * tapset-itrace.cxx (emit_module_decls): Updated usr_itrace_init() call. * runtime/autoconf-find-task-pid.c: Removed, since only user_itrace_init() was using it. * buildrun.cxx (compile_pass): Removed autoconf-find-task-pid.c test.
* * tapsets.cxx (dwarf_builder::probe_table::convert_probe):Stan Cox2009-07-202-59/+54
| | | | | | First check kprobe and utrace (did we arrive via stap?) then check if probe arg matches mark("NAME") * sdt.h (STAP_PROBE?_): Use STAP_GUARD for stap check, not gettid.
