2017-01-10Add constructor and destructor to demangle_parse_infoTom Tromey1-5/+1
This adds a constructor and destructor to demangle_parse_info, and then changes all the users to use them. This removes make_cleanup_cp_demangled_name_parse_free and its single use. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-type.c (typy_legacy_template_argument): Update. * cp-support.h (struct demangle_parse_info) (demangle_parse_info, ~demangle_parse_info): Declare new members. (cp_demangled_name_to_comp): Return unique_ptr. (cp_demangled_name_parse_free) (make_cleanup_cp_demangled_name_parse_free) (cp_new_demangle_parse_info): Remove. * cp-support.c (do_demangled_name_parse_free_cleanup) (make_cleanup_cp_demangled_name_parse_free): Remove. (inspect_type, cp_canonicalize_string_full) (cp_canonicalize_string): Update. (mangled_name_to_comp): Change return type. (cp_class_name_from_physname, method_name_from_physname) (cp_func_name, cp_remove_params): Update. * cp-name-parser.y (demangle_parse_info): New constructor, from cp_new_demangle_parse_info. (~demangle_parse_info): New destructor, from cp_demangled_name_parse_free. (cp_merge_demangle_parse_infos): Update. (cp_demangled_name_to_comp): Change return type.
2017-01-10Remove cleanups from execute_gdb_commandTom Tromey1-6/+4
This replaces a cleanup in execute_gdb_command with an instance of std::string. Testing showed that this originally missed a cleanup that was returned by prevent_dont_repeat. This version of the patch changes prevent_dont_repeat to return a scoped_restore rather than a cleanup. 2017-01-10 Tom Tromey <tom@tromey.com> * top.c (prevent_dont_repeat): Change return type. * python/python.c (execute_gdb_command): Use std::string. Update. * guile/guile.c (gdbscm_execute_gdb_command): Update. * command.h (prevent_dont_repeat): Change return type. * breakpoint.c (bpstat_do_actions_1): Update.
2017-01-10Add scoped_value_markTom Tromey1-44/+18
This adds a scoped_value_mark class, that records the value mark in the constructor and then calls value_free_to_mark in the destructor. It then updates various spots in gdb to use this class, rather than a cleanup. It would be better overall to replace "struct value *" with a shared_ptr, maybe eliminating the need for this class (watchpoints would perhaps need some new mechanism as well). However, that's difficult to do. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-value.c (valpy_dereference, valpy_referenced_value) (valpy_reference_value, valpy_const_value, valpy_get_address) (valpy_get_dynamic_type, valpy_lazy_string, valpy_do_cast) (valpy_getitem, valpy_call, valpy_binop_throw, valpy_negative) (valpy_absolute, valpy_richcompare_throw): Use scoped_value_mark. * dwarf2loc.c (dwarf2_loc_desc_get_symbol_read_needs): Use scoped_value_mark. * dwarf2-frame.c (execute_stack_op): Use scoped_value_mark. * value.h (scoped_value_mark): New class.
2017-01-10Use class to manage BFD reference countsTom Tromey1-2/+2
This introduces a new specialization of gdb::ref_ptr that can be used to manage BFD reference counts. Then it changes most places in gdb to use this new class, rather than explicit reference-counting or cleanups. This patch removes make_cleanup_bfd_unref. If you look you will see a couple of spots using "release" where a use of gdb_bfd_ref_ptr would be cleaner. These will be fixed in the next patch. I think this patch fixes some latent bugs. For example, it seems to me that previously objfpy_add_separate_debug_file leaked a BFD. I'm not 100% certain that the macho_symfile_read_all_oso change is correct. The existing code here is hard for me to follow. One goal of this sort of automated reference counting, though, is to make it more difficult to make logic errors; so hopefully the code is clear now. 2017-01-10 Tom Tromey <tom@tromey.com> * windows-tdep.c (windows_xfer_shared_library): Update. * windows-nat.c (windows_make_so): Update. * utils.h (make_cleanup_bfd_unref): Remove. * utils.c (do_bfd_close_cleanup, make_cleanup_bfd_unref): Remove. * symfile.h (symfile_bfd_open) (find_separate_debug_file_in_section): Return gdb_bfd_ref_ptr. * symfile.c (read_symbols, symbol_file_add) (separate_debug_file_exists): Update.

(find_separate_debug_file_by_buildid): Update.
2017-01-10Add gdb_ref_ptr.hTom Tromey1-126/+9
This adds a new gdb_ref_ptr.h, that implements a reference-counting smart pointer class, where the user of the class supplies a reference-counting policy object. This class will be used in the next patch, which changes most explicit BFD reference counts to use this new type. Meanwhile, this patch changes gdbpy_ref to be a specialization of this new class. This change required adding new nullptr_t overloads some operators in gdb_ref_ptr.h. I suspect this was needed because some Python header redefines NULL, but I'm not certain. 2017-01-10 Tom Tromey <tom@tromey.com> * common/gdb_ref_ptr.h: New file. * python/py-ref.h (struct gdbpy_ref_policy): New. (gdbpy_ref): Now a typedef.
2017-01-10Remove make_cleanup_py_decref and make_cleanup_py_xdecrefTom Tromey2-45/+0
make_cleanup_py_decref and make_cleanup_py_xdecref are now unused, so this patch removes themm. Future Python changes should use gdbpy_ref instead. 2017-01-10 Tom Tromey <tom@tromey.com> * python/python-internal.h (make_cleanup_py_decref) (make_cleanup_py_xdecref): Don't declare. * python/py-utils.c (py_decref, make_cleanup_py_decref) (py_xdecref, make_cleanup_py_xdecref): Remove.
2017-01-10Use gdbpy_ref rather than make_cleanup_py_decrefTom Tromey1-31/+28
This changes some spots in py-framefilter.c to use gdbpy_ref rather than make_cleanup_py_decref or make_cleanup_py_xdecref. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-framefilter.c (py_mi_print_variables): Use gdbpy_ref. (py_print_locals, enumerate_locals, py_print_args): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in enumerate_argsTom Tromey1-35/+21
This changes enumerate_args to use gdbpy_ref, and gets rid of many gotos. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-framefilter.c (enumerate_args): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in py-utils.cTom Tromey1-34/+15
This changes more places in py-utils.c to use gdbpy_ref. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-utils.c (unicode_to_encoded_string) (python_string_to_target_string) (python_string_to_target_python_string) (python_string_to_host_string, gdbpy_obj_to_string) (get_addr_from_python): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in pyuw_object_attribute_to_pointerTom Tromey1-3/+2
This changes pyuw_object_attribute_to_pointer to use gdbpy_ref. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-unwind.c (pyuw_object_attribute_to_pointer): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in python.cTom Tromey1-67/+53
This changes more places in python.c to use gdbpy_ref. Additionally, previously gdbpy_apply_type_printers would return EXT_LANG_RC_ERROR if a type printer returned None. However, that doesn't seem correct to me; this patch changes it to return EXT_LANG_RC_NOP in this case. 2017-01-10 Tom Tromey <tom@tromey.com> * python/python.c (eval_python_command, gdbpy_decode_line) (gdbpy_run_events, gdbpy_start_type_printers) (gdbpy_apply_type_printers): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in py-param.cTom Tromey1-10/+8

2017-01-10Use gdbpy_ref in py-inferior.cTom Tromey1-17/+6
This changes py-inferior.c to use gdbpy_ref in more places. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-inferior.c (find_thread_object, build_inferior_list): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in py_print_frameTom Tromey1-10/+4
This changes py_print_frame to use gdbpy_ref in more places. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-framefilter.c (py_print_frame): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in bpfinishpy_out_of_scopeTom Tromey1-4/+3
This changes bpfinishpy_out_of_scope to use gdbpy_ref. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-finishbreakpoint.c (bpfinishpy_out_of_scope): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in py-cmd.cTom Tromey1-51/+30
This changes py-cmd.c to use gdbpy_ref in more places. This also fixes a latent memory leak in cmdpy_completer_helper, which unnecessarily increfs the result of PyObject_CallMethodObjArgs. This is not needed because that function returns a new reference. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-cmd.c (cmdpy_completer_helper): Use gdbpy_ref. Remove extra incref. (cmdpy_completer_handle_brkchars, cmdpy_completer, cmdpy_init): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in gdbpy_breakpoint_cond_says_stopTom Tromey1-5/+3
This changes gdbpy_breakpoint_cond_says_stop to use gdbpy_ref rather than explicit reference management. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-breakpoint.c (gdbpy_breakpoint_cond_says_stop): Use gdbpy_ref.
2017-01-10Use gdbpy_ref in archpy_disassembleTom Tromey1-20/+9
This changes archpy_disassemble to use gdbpy_ref. It also fixes a latent bug where archpy_disassemble was decref'ing the results of a all to PyArg_ParseTupleAndKeywords. This is incorrect because PyArg_ParseTupleAndKeywords returns borrowed references. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-arch.c (archpy_disassemble): Use gdbpy_ref. Don't decref results of PyArg_ParseTupleAndKeywords.
2017-01-10Change python_run_simple_file to use gdbpy_refTom Tromey1-13/+5
This changes python_run_simple_file to use gdbpy_ref and unique_xmalloc_ptr. Thi fixes a latent bug in this function, where the error path previously ran the cleanups and then referred to one of the objects just freed. 2017-01-10 Tom Tromey <tom@tromey.com> * python/python.c (python_run_simple_file): Use unique_xmalloc_ptr, gdbpy_ref.
2017-01-10Use gdbpy_ref in py-prettyprint.cTom Tromey1-114/+92
This changes some spots in py-prettyprint.c to use gdbpy_ref. It also changes push_dummy_python_frame to be a class, rather than having it create a cleanup. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-prettyprint.c (print_stack_unless_memory_error) (print_string_repr, print_children): Use gdbpy_ref. (dummy_python_frame): New class. (dummy_python_frame::dummy_python_frame): Rename from push_dummy_python_frame. (py_restore_tstate): Remove.
2017-01-10Use gdbpy_ref in py_print_frameTom Tromey1-29/+12
This changes py_print_frame to use gdbpy_ref in a few spots. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-framefilter.c (py_print_frame): Use gdbpy_ref.
2017-01-10Remove ensure_python_envTom Tromey2-26/+0
All of gdb has been converted away from ensure_python_env and varobj_ensure_python_env now; so remove them. 2017-01-10 Tom Tromey <tom@tromey.com> * python/python.c (ensure_python_env, restore_python_env): Remove. * python/python-internal.h (ensure_python_env): Don't declare. * varobj.h (varobj_ensure_python_env): Don't declare. * varobj.c (varobj_ensure_python_env): Remove.
2017-01-10Change type of encoding argument to gdbpy_extract_lazy_stringTom Tromey3-12/+10
This changes gdbpy_extract_lazy_string's "encoding" argument to be a unique_xmalloc_ptr. I chose this rather than std::string because it can sometimes be NULL. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-prettyprint.c (print_string_repr, print_children): Update. * python/py-lazy-string.c (gdbpy_extract_lazy_string): Change type of "encoding". * varobj.c (varobj_value_get_print_value): Update. * python/python-internal.h (gdbpy_extract_lazy_string): Update.
2017-01-10Use gdbpy_enter in python.cTom Tromey1-45/+37
This changes the last functions in python.c to use gdbpy_enter. I split gdbpy_finish_initialization into two functions in order to avoid some "goto"s. 2017-01-10 Tom Tromey <tom@tromey.com> * python/python.c (python_command): Use gdbpy_enter, gdbpy_ref. (do_finish_initialization): New function. Use gdbpy_ref. (gdbpy_finish_initialization): Use gdbpy_enter. Call do_finish_initialization.
2017-01-10Use gdbpy_enter in py-param.cTom Tromey1-40/+35
This converts the remaining functions in py-param.c to use gdbpy_enter. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-param.c (get_set_value, get_show_value): Use gdbpy_enter, gdbpy_ref.
2017-01-10Use gdbpy_enter in fnpy_callTom Tromey1-21/+11
This changes fnpy_call to use gdbpy_enter and gdbpy_ref. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-function.c (fnpy_call): Use gdbpy_enter, gdbpy_ref.
2017-01-10Use gdbpy_enter in cmdpy_functionTom Tromey1-16/+10

2017-01-10Introduce gdbpy_enter_varobj and use itTom Tromey2-13/+19
This introduces gdbpy_enter_varobj, a subclass of gdbpy_enter; then changes one function in py-varobj.c to use it. gdbpy_enter_varobj takes a varobj as an argument, similar to varobj_ensure_python_env. 2017-01-10 Tom Tromey <tom@tromey.com> * varobj.c (gdbpy_enter_varobj): New constructor. * python/python-internal.h (gdbpy_enter_varobj): New class. * python/py-varobj.c (py_varobj_get_iterator): Use gdbpy_enter_varobj.
2017-01-10Use gdbpy_enter in py-xmethod.cTom Tromey1-91/+74
This changes the remaining functions in py-xmethod.c to use gdbpy_enter; using gdbpy_ref and unique_xmalloc_ptr as appropriate. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-xmethods.c (gdbpy_get_xmethod_result_type): Use gdbpy_enter, gdbpy_ref, unique_xmalloc_ptr. (gdbpy_invoke_xmethod): Use gdbpy_ref, gdbpy_enter. (gdbpy_get_xmethod_arg_types): Use gdbpy_ref, unique_xmalloc_ptr. (gdbpy_get_xmethod_arg_types): Use gdbpy_ref, gdbpy_enter.
2017-01-10Use gdbpy_ref in invoke_match_methodTom Tromey1-38/+12
Change invoke_match_method to use gdbpy_ref. I neglected to convert this function in my earlier series. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-xmethods.c (invoke_match_method): Use gdbpy_ref.
2017-01-10Use gdbpy_enter in gdbpy_get_matching_xmethod_workersTom Tromey1-95/+58
Change gdbpy_get_matching_xmethod_workers to use gdbpy_enter and gdbpy_ref. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-xmethods.c (gdbpy_get_matching_xmethod_workers): use gdbpy_enter, gdbpy_ref.
2017-01-10Use gdbpy_enter in python_interactive_commandTom Tromey1-1/+1
This changes python_interactive_command to use gdbpy_enter. Previously this function was leaving a dangling cleanup -- this is sort of ok in a command function, but IMO it's still better to clean up. 2017-01-10 Tom Tromey <tom@tromey.com> * python/python.c (python_interactive_command): Use gdbpy_enter.
2017-01-10Use gdbpy_enter in gdbpy_before_prompt_hookTom Tromey1-39/+33

2017-01-10Use gdbpy_enter in py-prettyprint.cTom Tromey1-30/+15
Change py-prettyprint.c to use gdbpy_enter. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-prettyprint.c (gdbpy_apply_val_pretty_printer): Use gdbpy_enter, gdbpy_ref, unique_xmalloc_ptr.
2017-01-10Introduce htab_up and use gdbpy_enter in py-framefilter.cTom Tromey1-34/+21
This introduces a new "htab_up" typedef, which is a std::unique_ptr that can call htab_delete. Then it changes some code in py-framefilter.c to use both gdbpy_enter and the new htab_up. 2017-01-10 Tom Tromey <tom@tromey.com> * utils.h (htab_deleter): New struct. (htab_up): New typedef. * python/py-framefilter.c (gdbpy_apply_frame_filter): Use gdbpy_enter, gdbpy_ref, htab_up.
2017-01-10Use gdbpy_enter in py-unwind.cTom Tromey1-39/+33
Change py-unwind.c to use gdbpy_enter. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-unwind.c (pending_frame_invalidate): Remove. (pyuw_sniffer): Use gdbpy_enter and gdbpy_ref.
