* libdwfl: Add dwfl_core_file_attach and dwfl_linux_proc_attach.Mark Wielaard2013-12-311-0/+10
| | | | | | | | | | | | | | Rewrite __libdwfl_attach_state_for_pid and __libdwfl_attach_state_for_core as public functions and don't call them from dwfl_linux_proc_report and dwfl_core_file_report anymore. This lets the user attach state explicitly independ from how the dwfl modules have been reported. Since attaching state is an explicit action now the error can be returned directly and we don't need to keep track of process_attach_error. dwfl_linux_proc_attach lets the user can tell libdwfl whether caller takes care of ptrace attaching and stopping the threads under inspection, or whether the callback needs to take care of that and detaching again.

(dwfl_core_file_report): Move raw segments reporting lower. New variable r_debug_info, pass it to dwfl_segment_report_module. Call clear_r_debug_info in the end. Return sum of LISTED and SNIFFED. * dwfl_module_build_id.c (check_notes): Move into __libdwfl_find_elf_build_id. (__libdwfl_find_build_id): Rename to ... (__libdwfl_find_elf_build_id): ... here. Add parameters build_id_bits, build_id_elfaddr and build_id_len. Verify MOD vs. ELF. (__libdwfl_find_elf_build_id) (check_notes): Remove parameters mod and set, rename data_vaddr to data_elfaddr. Do not call found_build_id. (__libdwfl_find_elf_build_id): Update the check_notes caller, do not adjust its data_elfaddr parameter. (__libdwfl_find_build_id): New wrapper of __libdwfl_find_elf_build_id. * dwfl_segment_report_module.c (dwfl_segment_report_module): New parameter r_debug_info. New variable name_is_final. Adjust addresses according to R_DEBUG_INFO->MODULE. Check conflicts against DWFL. Do not overwrite NAME by SONAME if NAME_IS_FINAL. * libdwflP.h (__libdwfl_find_elf_build_id): New declaration. (struct r_debug_info_module, struct r_debug_info): New definitions. (dwfl_segment_report_module, dwfl_link_map_report): Add parameter r_debug_info. * link_map.c: Include fcntl.h. (report_r_debug): Add parameter r_debug_info, describe it in the function comment. Delete dwfl_addrmodule call and its dependent code. Verify build-id before calling dwfl_report_elf, also supply executable_for_core to it. Store r_debug_info->module info when appropriate. (dwfl_link_map_report): Add parameter r_debug_info. New variable in_ok. Try to read IN from EXECUTABLE_FOR_CORE. Update report_r_debug caller parameters. tests/ 2013-05-30 Jan Kratochvil <[email protected]> * Makefile.am (EXTRA_DIST): Add test-core-lib.so.bz2, test-core.core.bz2 and test-core.exec.bz2. * run-addrname-test.sh: New test for these files. * run-unstrip-n.sh: Update expected output.

* libdwfl: Use actual file names in parse_opt failure cases.Mark Wielaard2013-02-101-3/+7
| | | | | | | | | When handling ARGP_KEY_SUCCESS the failure handling code would use 'arg' as failure string. But 'arg' would be NULL in such cases leading to failure messages like: "cannot open '(null)': No such file or directory". Use opt->e and opt->core explicitly to show file names that caused failure.
