| * Fix relay_old implementation of fsize_max and fnum_max.Masami Hiramatsu2009-09-091-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | With old relayfs, out_fd is used only when non-bulk mode. 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.

* PR10524: reduce massive-uprobe script modules' .data consumptionFrank Ch. Eigler2009-09-085-127/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | | The general approach is to rip out task_finder_tgt's from all over the place (including the unwindsym vmcbs, and the stap_uprobe_specs), and instead have a small handful of them: one for all unwindsyms, and one per abstract probed process (PID or NAME). These are in turn shared by all new stap_unwind_specs by index.

* bz10475.exp: Use filp_open which has a constant const char argument for test.Mark Wielaard2009-09-071-4/+3
| | | | | | | | | For some reason the do_filp_open const char *pathname argument has changed its name between different kernel versions. Luckily filp_open has a cont char *filename argument that is constant between versions (the test needs a const char* argument to do an array operation on). * testsuite/semok/bz10475.stp: Use filp_open instead of do_filp_open.
* PR10613 sys32_ustat is renamed compat_sys_ustat in 2.6.30 kernel.Mark Wielaard2009-09-072-2/+25
| | | | | | | | | | Note that the new compat_sys_ustat is asmlinkage and has a differently named argument for the user struct. * tapset/syscalls2.stp (syscall.ustat32): Add compat_sys_ustat variant.

| | | | | | | | | | | | | | | | | | | | | | | | We already use regexp for function/file blacklisting, so this just makes the section blacklisting consistent with the rest. * dwflpp.cxx (dwflpp::blacklisted_p): Use regexec instead of section==. (dwflpp::build_blacklist): Build blacklist_section too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In C++, identical functions included in multiple CUs will get merged at link time into a single instance. We need to make sure that inlines within those merged functions are not probed multiple times. * tapsets.cxx (inline_instance_info::operator<): Used for set support. (dwarf_query::handle_query_module): Clear inline_dupes on each module. (query_dwarf_inline_instance): Squash this inline instance if it's already in the inline_dupes set.
| * | PR10572: Allow duplicate function names in a CUJosh Stone2009-09-023-24/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We can't assume that a given function name will only appear once in a CU. In C++, two functions may have the same name in different classes or namespaces, or even in the same scope with overloaded parameters. Even in C, the compiler may generate multiple copies of a single function with different optimizations. We now use a multimap for function names, so we shouldn't miss any. * dwflpp.h (cu_type_cache_t, mod_cu_type_cache_t): New typedef to keep a normal map for the global_alias_cache. (cu_function_cache_t): Use a multimap for function names. * dwflpp.cxx (dwflpp::iterate_over_functions): Walk over the range of exactly-matching functions. * tapsets.cxx (query_dwarf_func): Don't abort after seeing an exact match -- there could be more to come.

| * | Provide backward-compatible unordered_map/setJosh Stone2009-09-022-20/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were defining our own stap_map with a ::type to let us use typedefs to use the new unordered_map if available, or hash_map otherwise. Since unordered_map is the future direction, I'm changing our code to use that directly. The backward-compatible version is a #define to hash_map, which has a compatible interface. While I'm at it, let's also define unordered_multimap, unordered_set, and unordered_multiset. * unordered.h: New. * dwflpp.h (stap_map): Removed. (cache typedefs): Use the unordered name now.
