Do not send queries on secondary UIs This is a follow-up to https://sourceware.org/ml/gdb-patches/2017-02/msg00261.html This patch restricts queries to the main UI, which allows to avoid two different problems. The first one is that GDB is issuing queries on secondary MI channels for which a TTY is allocated. The second one is that GDB is not able to handle queries on two (CLI) UIs simultaneously. Restricting queries to the main UI allows to bypass these two problems. More details on how/why these two problems happen: 1. Queries on secondary MI UI The current criterion to decide if we should query the user is whether the input stream is a TTY. The original way to start GDB in MI mode from a front-end was to create a subprocess with pipes to its stdin/stdout. In this case, the input was considered non-interactive and queries were auto-answered. Now that front-ends can create the MI channel as a separate UI connected to a dedicated TTY, GDB now considers this input stream as interactive and sends queries to it. By restricting queries to the main UI, we make sure we never query on the secondary MI UI. 2. Simultaneous queries As Pedro stated it, when you have two queries on two different CLI UIs at the same time, you end up with the following pseudo stack: #0 gdb_readline_wrapper #1 defaulted_query // for UI #2 #2 handle_command #3 execute_command ("handle SIGTRAP" .... #4 stdin_event_handler // input on UI #2 #5 gdb_do_one_event #7 gdb_readline_wrapper #8 defaulted_query // for UI #1 #9 handle_command #10 execute_command ("handle SIGINT" .... #11 stdin_event_handler // input on UI #1 #12 gdb_do_one_event #13 gdb_readline_wrapper trying to answer the query on UI #1 will therefore answer for UI #2. By restricting the queries to the main UI, we ensure that there will never be more than one pending query, since you can't have two queries on a UI at the same time. I added a snippet to gdb.base/new-ui.exp to verify that we get a query on the main UI, but that we don't on the secondary one (or, more precisely, that it gets auto-answered). gdb/ChangeLog: * utils.c (defaulted_query): Don't query on secondary UIs. gdb/testsuite/ChangeLog: * gdb.base/new-ui.exp (do_test): Test queries behavior on main and extra UIs.

Eliminate interp::quiet_p This commit removes interp::quiet_p / interp_quiet_p / interp_set_quiet, because AFAICS, it doesn't really do anything. interp_quiet is only ever checked inside interp_set nowadays: if (!first_time && !interp_quiet_p (interp)) { xsnprintf (buffer, sizeof (buffer), "Switching to interpreter \"%.24s\".\n", interp->name); current_uiout->text (buffer); } I did a bit of archaelogy, and found that back in 4a8f6654 (2003), it was also called in another place, to decide whether to print the CLI prompt. AFAICS, that condition is always false today, making that if/then block always dead code. If we remove that code, then there are no interp_quiet_p uses left in the tree, so we can remove it all. There are two paths that lead to interp_set calls: #1 - When installing the top level interpreter. In this case, FIRST_TIME is true. #2 - In interpreter_exec_cmd. In this case, the interpreter is always set quiet before interp_set is called. Grepping a gdb.log of an x86_64 GNU/Linux run for "Switching to interpreter" (before this patch) doesn't find any hits. I suspect the intention of this message was to support something like a "set interpreter ..." command that would change the interpreter permanently. But there's no such command.

C++-fy struct interp/cli_interp/tui_interp/mi_interp - The interp->data field disappears, since we can put data in the interpreter directly now. The "init" method remains in place, but it now returns void. - A few places check if the interpreter method is NULL before calling it, and also check whether the method returns true/false. For some of those methods, all current implementations always return true. In those cases, this commit makes the C++-fied method return void instead and cleans up the callers.

The result is that this sequence of commands crashes GDB: -gdb-set logging on -gdb-set logging redirect on Program received signal SIGSEGV, Segmentation fault. 0x00000000008dd7bc in gdb_flush (file=0x2a097f0) at /home/pedro/gdb/mygit/cxx-convertion/src/gdb/ui-file.c:95 194 file->to_flush (file); (top-gdb) bt #0 0x00000000008dd7bc in gdb_flush(ui_file*) (file=0x2a097f0) at /home/pedro/gdb/mygit/cxx-convertion/src/gdb/ui-file.c:95 #1 0x00000000007b5f34 in gdb_wait_for_event(int) (block=0) at /home/pedro/gdb/mygit/cxx-convertion/src/gdb/event-loop.c:752 #2 0x00000000007b52b6 in gdb_do_one_event() () at /home/pedro/gdb/mygit/cxx-convertion/src/gdb/event-loop.c:322 #3 0x00000000007b5362 in start_event_loop() () at /home/pedro/gdb/mygit/cxx-convertion/src/gdb/event-loop.c:371 #4 0x000000000082704a in captured_command_loop(void*) (data=0x0) at /home/pedro/gdb/mygit/cxx-convertion/src/gdb/main.c:325 #5 0x00000000007b8d7c in catch_errors(int (*)(void*), void*, char*, return_mask) (func=0x827008 <captured_command_loop(void*)>, func_args=0x0, errstring=0x11dee51 "", mask=RETURN_MASK_ALL) at /home/pedro/gdb/mygit/cxx-convertion/src/gdb/exceptions.c:236 #6 0x000000000082839b in captured_main(void*) (data=0x7fffffffd820) at /home/pedro/gdb/mygit/cxx-convertion/src/gdb/main.c:1148 During symbol reading, cannot get low and high bounds for subprogram DIE at 24065. #7 0x00000000008283c4 in gdb_main(captured_main_args*) (args=0x7fffffffd820) at /home/pedro/gdb/mygit/cxx-convertion/src/gdb/main.c:1158 #8 0x0000000000412d4d in main(int, char**) (argc=4, argv=0x7fffffffd928) at /home/pedro/gdb/mygit/cxx-convertion/src/gdb/gdb.c:32 The handling of redirect on the fly is not really a use case we need to handle, IMO.

Move "tee" building down to interpreter::set_logging_proc This patch gets rid of this hack in mi_set_logging: /* The tee created already is based on gdb_stdout, which for MI is a console and so we end up in an infinite loop of console writing to ui_file writing to console etc. So discard the existing tee (it hasn't been used yet, and MI won't ever use it), and create one based on raw_stdout instead. */ By pushing down responsibility for the tee creation to the interpreter. I.e., pushing the CLI bits out of handle_redirections down to the CLI interpreter's set_logging_proc method. This fixes a few leaks that I spotted, and then confirmed with "valgrind --leak-check=full": [...] ==21429== 56 (32 direct, 24 indirect) bytes in 1 blocks are definitely lost in loss record 30,243 of 34,980 ==21429== at 0x4C29216: operator new(unsigned long) (vg_replace_malloc.c:334) ==21429== by 0x62D9A9: mi_set_logging(interp*, int, ui_file*, ui_file*) (mi-interp.c:1395) ==21429== by 0x810B8A: current_interp_set_logging(int, ui_file*, ui_file*) (interps.c:360) ==21429== by 0x61C537: handle_redirections(int) (cli-logging.c:162) ==21429== by 0x61C6EC: set_logging_on(char*, int) (cli-logging.c:190) ==21429== by 0x6163BE: do_cfunc(cmd_list_element*, char*, int) (cli-decode.c:105) ==21429== by 0x6193C1: cmd_func(cmd_list_element*, char*, int) (cli-decode.c:1913) ==21429== by 0x8DB790: execute_command(char*, int) (top.c:674) ==21429== by 0x632AE6: mi_execute_cli_command(char const*, int, char const*) (mi-main.c:2343) ==21429== by 0x6329BA: mi_cmd_execute(mi_parse*) (mi-main.c:2306) ==21429== by 0x631E19: captured_mi_execute_command(ui_out*, mi_parse*) (mi-main.c:1998) ==21429== by 0x632389: mi_execute_command(char const*, int) (mi-main.c:2163) ==21429== [...] ==26635== 24 bytes in 1 blocks are definitely lost in loss record 20,740 of 34,995 ==26635== at 0x4C29216: operator new(unsigned long) (vg_replace_malloc.c:334) ==26635== by 0x61C355: handle_redirections(int) (cli-logging.c:131) ==26635== by 0x61C6EC: set_logging_on(char*, int) (cli-logging.c:190) ==26635== by 0x6163BE: do_cfunc(cmd_list_element*, char*, int) (cli-decode.c:105) ==26635== by 0x6193C1: cmd_func(cmd_list_element*, char*, int) (cli-decode.c:1913) ==26635== by 0x8DB7BC: execute_command(char*, int) (top.c:674) ==26635== by 0x7B9132: command_handler(char*) (event-top.c:590) ==26635== by 0x7B94F7: command_line_handler(char*) (event-top.c:780) ==26635== by 0x7B8ABB: gdb_rl_callback_handler(char*) (event-top.c:213) ==26635== by 0x933CE9: rl_callback_read_char (callback.c:220) ==26635== by 0x7B89ED: gdb_rl_callback_read_char_wrapper_noexcept() (event-top.c:175) ==26635== by 0x7B8A49: gdb_rl_callback_read_char_wrapper(void*) (event-top.c:192) One is fixed by transfering ownership of the log file to the tee.

Eliminate make_cleanup_ui_file_delete / make ui_file a class hierarchy This patch starts from the desire to eliminate make_cleanup_ui_file_delete, but then goes beyond. It makes ui_file & friends a real C++ class hierarchy, and switches temporary ui_file-like objects to stack-based allocation. - mem_fileopen -> string_file mem_fileopen is replaced with a new string_file class that is treated as a value class created on the stack. This alone eliminates most make_cleanup_ui_file_delete calls, and, simplifies code a whole lot (diffstat shows around 1k loc dropped.) string_file's internal buffer is a std::string, thus the "string" in the name. This simplifies the implementation much, compared to mem_fileopen, which managed growing its internal buffer manually. - ui_file_as_string, ui_file_strdup, ui_file_obsavestring all gone The new string_file class has a string() method that provides direct writable access to the internal std::string buffer. This replaced ui_file_as_string, which forced a copy of the same data the stream had inside. With direct access via a writable reference, we can instead move the string out of the string_stream, avoiding deep string copying. Related, ui_file_xstrdup calls are replaced with xstrdup'ping the stream's string, and ui_file_obsavestring is replaced by obstack_copy0. With all those out of the way, getting rid of the weird ui_file_put mechanism was possible. - New ui_file::printf, ui_file::puts, etc. methods These simplify / clarify client code. I considered splitting client-code changes, like these, e.g.: - stb = mem_fileopen (); - fprintf_unfiltered (stb, "%s%s%s", - _("The valid values are:\n"), - regdesc, - _("The default is \"std\".")); + string_file stb; + stb.printf ("%s%s%s", + _("The valid values are:\n"), + regdesc, + _("The default is \"std\".")); In two steps, with the first step leaving fprintf_unfiltered (etc.) calls in place, and only afterwards do a pass to change all those to call stb.printf etc.. I didn't do that split, because (when I tried), it turned out to be pointless make-work: the first pass would have to touch the fprintf_unfiltered line anyway, to replace "stb" with "&stb". - gdb_fopen replaced with stack-based objects This avoids the need for cleanups or unique_ptr's. I.e., this: struct ui_file *file = gdb_fopen (filename, "w"); if (filename == NULL) perror_with_name (filename); cleanups = make_cleanup_ui_file_delete (file); // use file. do_cleanups (cleanups); is replaced with this: stdio_file file; if (!file.open (filename, "w")) perror_with_name (filename); // use file. - odd contorsions in null_file_write / null_file_fputs around when to call to_fputs / to_write eliminated. - Global null_stream object A few places that were allocating a ui_file in order to print to "nowhere" are adjusted to instead refer to a new 'null_stream' global stream. - TUI's tui_sfileopen eliminated. TUI's ui_file much simplified The TUI's ui_file was serving a dual purpose. It supported being used as string buffer, and supported being backed by a stdio FILE. The string buffer part is gone, replaced by using of string_file. The 'FILE *' support is now much simplified, by making the TUI's ui_file inherit from stdio_file. gdb/ChangeLog: 2017-02-02 Pedro Alves <palves@redhat.com> * ada-lang.c (type_as_string): Use string_file. * ada-valprint.c (ada_print_floating): Use string_file. * ada-varobj.c (ada_varobj_scalar_image) (ada_varobj_get_value_image): Use string_file. * aix-thread.c (aix_thread_extra_thread_info): Use string_file. * arm-tdep.c (_initialize_arm_tdep): Use string_printf. * breakpoint.c (update_inserted_breakpoint_locations) (insert_breakpoint_locations, reattach_breakpoints) (print_breakpoint_location, print_one_detail_ranged_breakpoint) (print_it_watchpoint): Use string_file.

Add back gdb_pretty_print_insn ui_file_rewind is a ui_file method that only really works with mem buffer files, and is a nop on other ui_file types. It'd be desirable to eliminate it from the base ui_file interface, and move it to the "mem_fileopen" subclass of ui_file instead. A following patch does just that. Unfortunately, there are a couple references to ui_file_rewind inside gdb_disassembler::pretty_print_insn that were made harder to eliminate with the recent addition of the gdb_disassembler wrapper. Before the gdb_disassembler wrapper was added, in commit e47ad6c0bd7aa3 ("Refactor disassembly code"), gdb_pretty_print_insn used to be passed a ui_file pointer as argument, and it was simple to adjust that pointer be a "mem_fileopen" ui_file pointer instead, since there's only one gdb_pretty_print_insn caller. That commit made gdb_pretty_print_insn be a method of gdb_disassembler, and removed the method's ui_file parameter at the same time, replaced by referencing the gdb_disassembler's stream instead. The trouble is that a gdb_disassembler can be instantiated with a pointer any kind of ui_file. Casting the gdb_disassembler's stream to a mem_fileopen ui_file inside gdb_disassembler::pretty_print_insn in order to call the reset method would be gross hack. The fix here is to: - make gdb_disassembler::pretty_print_insn a be free function again instead of a method of gdb_disassembler. I.e., bring back gdb_pretty_print_insn. - but, don't add back the ui_file * parameter. Instead, move the mem_fileopen allocation inside. That is a better interface, given that the ui_file is only ever used as temporary scratch buffer as an implementation detail of gdb_pretty_print_insn. The function's real "where to send output" parameter is the ui_out pointer. (A following patch will add back buffer reuse across invocations differently). - don't add back a disassemble_info pointer either. That used to be necessary for this bit: err = m_di.read_memory_func (pc, &data, 1, &m_di); if (err != 0) m_di.memory_error_func (err, pc, &m_di); ... but AFAIK, it's not really necessary. We can replace those three lines with a call to read_code. This seems to fix a regression even, because before commit d8b49cf0c891d0 ("Don't throw exception in dis_asm_memory_error"), that memory_error_func call would throw an error/exception, but now it only records the error in the gdb_disassembler's m_err_memaddr field. (read_code throws on error.) With all these, gdb_pretty_print_insn is completely layered on top of gdb_disassembler only using the latter's public API. gdb/ChangeLog: 2017-02-02 Pedro Alves <palves@redhat.com> * disasm.c (gdb_disassembler::pretty_print_insn): Rename to...

Big-endian targets: Don't ignore offset into DW_OP_implicit_value When a variable's location is expressed as DW_OP_implicit_value, but the given value is longer than needed, which bytes should be used? GDB's current logic was introduced with a patch from 2011 and uses the "least significant" bytes: https://sourceware.org/ml/gdb-patches/2011-08/msg00123.html Now consider a sub-value from such a location at a given offset, accessed through DW_OP_implicit_pointer. Which bytes should be used for that? The patch above *always* uses the last bytes on big-endian targets, ignoring the offset. E.g., given the code snippet const char foo[] = "Hello, world!"; const char *a = &foo[0]; const char *b = &foo[7]; assume that `foo' is described as DW_OP_implicit_value and `a' and `b' each as DW_OP_implicit_pointer into that value. Then with current GDB `*a' and `*b' yield the same result -- the string's zero terminator. This patch basically reverts the portion of the patch above that deals with DW_OP_implicit_value. This fixes the offset handling and also goes back to dropping the last instead of the first bytes on big-endian targets if the implicit value is longer than needed. The latter aspect of the change probably doesn't matter for actual programs, but simplifies the logic. The patch also cleans up the original code a bit and adds appropriate test cases. gdb/testsuite/ChangeLog: * gdb.dwarf2/dw2-op-stack-value.exp: Adjust expected result of taking a 2-byte value out of a 4-byte DWARF implicit value on big-endian targets. * gdb.dwarf2/nonvar-access.exp: Add more comments to existing logic.

And if the implicit value is longer than needed, extract the first bytes instead of the "least significant" ones.

Big-endian hosts: Fix "set architecture cris" The all-architectures-1.exp test case currently yields 66 FAILs on s390x, because the "set architecture" command fails each time when attempting to switch to "cris", "crisv32", or "cris:common_v10_v32". Actually, the command would succeed if the endianness had been set to "little" before. Instead, the test case sets the endianness to "auto", which results in "big" on s390x. So on x86_64: (gdb) set endian auto The target endianness is set automatically (currently little endian) (gdb) set architecture cris warning: A handler for the OS ABI "AIX" is not built into this configuration of GDB. Attempting to continue with the default cris settings. The target architecture is assumed to be cris But on s390x: (gdb) set endian auto The target endianness is set automatically (currently big endian) (gdb) set architecture cris Architecture `cris' not recognized. See also the test results for s390x and ppc64be: https://sourceware.org/ml/gdb-testers/2016-q4/msg05150.html https://sourceware.org/ml/gdb-testers/2016-q4/msg05713.html Indeed, cris_gdbarch_init in cris-tdep.c returns a failure unless the user-specified endianness is "little". Other architectures usually ignore the user-specified endianness and return a valid gdbarch anyhow, even if they can not really cope with the given endianness. This patch removes the check in cris-tdep.c and forces little-endian byte order instead. gdb/ChangeLog: * cris-tdep.c (cris_gdbarch_init): Remove check for info.byte_order and force it to BFD_ENDIAN_LITTLE.

Fix crash when loading a core with unexpected register section size When loading a core without an executable like so: $ gdb --core core for example often the gdbarch won't contain the iterate_over_regset_sections method. For example on ARM. This will generate a call to get_core_register_section with a NULL regset like at corelow.c:628 get_core_register_section (regcache, NULL, ".reg", 0, 0, "general-purpose", 1); However a check for REGSET_VARIABLE_SIZE in get_core_register_section assumes that regset is != NULL thus leading to a crash with this backtrace: (gdb) bt #0 0x000000000065907b in get_core_register_section (regcache=regcache@entry=0x2c26260, regset=regset@entry=0x0, name=name@entry=0xdbf7b2 ".reg", min_size=min_size@entry=0, which=which@entry=0, human_name=human_name@entry=0xdbac28 "general-purpose", required=1) at ../../gdb/corelow.c:542 #1 0x0000000000659b70 in get_core_registers (ops=<optimized out>, regcache=0x2c26260, regno=<optimized out>) at ../../gdb/corelow.c:628 #2 0x000000000076e5fb in target_fetch_registers (regcache=regcache@entry=0x2c26260, regno=regno@entry=15) at ../../gdb/target.c:3590 Note that commit: f962539ad23759 ("Warn if core file register section is larger than expected") introduced this issue. Thus releases > 7.8.2 are affected. Also, this would have been caught by gdb.base/corefile.exp but the problem is that this triggers only if the core dump is missing some data so that it's not recognized as a linux core dump, or it's not a linux core dump and the core file register section is larger than expected. So if you just create a core and read it on linux with ARM the osabi is detected properly and iterate_over_regset_sections is present and so the problem is not triggered. Thus creating a linux test for this with a crafted core that meets the problem requirements is non-trivial. This patch fixes this crash by adding a check for regset existence before running the condition. gdb/ChangeLog: * corelow.c (get_core_register_section): Check for regset existence before checking for REGSET_VARIABLE_SIZE.

Don't throw exception in dis_asm_memory_error Hi, GDB calls some APIs from opcodes to do disassembly and provide some call backs. This model makes troubles on C++ exception unwinding, because GDB is a C++ program, and opcodes is still compiled as C. As we can see, frame #10 and #12 are C++, while #frame 11 is C, #10 0x0000000000544228 in memory_error (err=TARGET_XFER_E_IO, memaddr=<optimized out>) at ../../binutils-gdb/gdb/corefile.c:237 #11 0x00000000006b0a54 in print_insn_aarch64 (pc=0, info=0xffffffffeeb0) at ../../binutils-gdb/opcodes/aarch64-dis.c:3185 #12 0x0000000000553590 in gdb_pretty_print_insn (gdbarch=gdbarch@entry=0xbbceb0, uiout=uiout@entry=0xbc73d0, di=di@entry=0xffffffffeeb0, insn=0xffffffffed40, insn@entry=0xffffffffed90, flags=flags@entry=0, C++ exception unwinder can't go across frame #11 unless it has unwind table. However, C program on many architectures doesn't have it in default. As a result, GDB aborts, which is described in PR 20939. This is not the first time we see this kind of problem. We've had a commit 89525768cd086a0798a504c81fdf7ebcd4c904e1 "Propagate GDB/C++ exceptions across readline using sj/lj-based TRY/CATCH". We can fix the disassembly bug in a similar way, this is the option one. Since opcodes is built with gdb, we fix this problem in a different way as we did for the same issue with readline. Instead of throwing exception in dis_asm_memory_error, we record the failed memory address, and throw exception when GDB returns from opcodes disassemblers. gdb: 2017-01-26 Yao Qi <yao.qi@linaro.org> Pedro Alves <palves@redhat.com> PR gdb/20939 * disasm.c (gdb_disassembler::dis_asm_memory_error): Don't call memory_error, save memaddr instead.

Refactor disassembly code This patch addes class gdb_disassembler, and refactor code to use it. The gdb_disassembler object is saved in disassember_info.application_data. However, disassember_info.application_data is already used by gdb for arm, mips spu, and scm-disasm. In arm and mips, .application_data is gdbarch, but we can still get gdbarch from gdb_disassember. The use of application_data in spu is a little bit complicated. It creates its own disassemble_info, and save spu_dis_asm_data in .application_data. This will overwrite the pointer to gdb_disassembler, so we need to find another place to save spu_dis_asm_data. I extend disassemble_info, and put "id" there. gdb: 2017-01-26 Pedro Alves <palves@redhat.com> Yao Qi <yao.qi@linaro.org> * arm-tdep.c: Include "disasm.h".

GDB 7.12.1 released.
Fix Py_DECREF being executed without holding the GIL When the gdbpy_ref objects get destroyed, they call Py_DECREF to decrement the reference counter of the python object they hold a reference to. Any time we call into the Python API, we should be holding the GIL. The gdbpy_enter object does that for us in an RAII-fashion. However, if gdbpy_enter is declared after a gdbpy_ref object in a function, gdbpy_enter's destructor will be called (and the GIL will be released) before gdbpy_ref's destructor is called. Therefore, we will end up calling Py_DECREF without holding the GIL. This became obvious with Python 3.6, where memory management functions have asserts to make sure that the GIL is held. This was exposed by tests py-as-string.exp, py-function.exp and py-xmethods. For example: (gdb) p $_as_string(enum_valid) Fatal Python error: Python memory allocator called without holding the GIL Current thread 0x00007f7f7b21c780 (most recent call first): [1] 18678 abort (core dumped) ./gdb -nx testsuite/outputs/gdb.python/py-as-string/py-as-string #0 0x00007ffff618bc37 in raise () from /lib/x86_64-linux-gnu/libc.so.6 #1 0x00007ffff618f028 in abort () from /lib/x86_64-linux-gnu/libc.so.6 #2 0x00007ffff6b104d6 in Py_FatalError (msg=msg@entry=0x7ffff6ba15b8 "Python memory allocator called without holding the GIL") at Python/pylifecycle.c:1457 #3 0x00007ffff6a37a68 in _PyMem_DebugCheckGIL () at Objects/obmalloc.c:1972 #4 0x00007ffff6a3804e in _PyMem_DebugFree (ctx=0x7ffff6e65290 <_PyMem_Debug+48>, ptr=0x24f8830) at Objects/obmalloc.c:1994 #5 0x00007ffff6a38e1d in PyMem_Free (ptr=<optimized out>) at Objects/obmalloc.c:442 #6 0x00007ffff6b866c6 in _PyFaulthandler_Fini () at ./Modules/faulthandler.c:1369 #7 0x00007ffff6b104bd in Py_FatalError (msg=msg@entry=0x7ffff6ba15b8 "Python memory allocator called without holding the GIL") at Python/pylifecycle.c:1431 #8 0x00007ffff6a37a68 in _PyMem_DebugCheckGIL () at Objects/obmalloc.c:1972 #9 0x00007ffff6a3804e in _PyMem_DebugFree (ctx=0x7ffff6e652c0 <_PyMem_Debug+96>, ptr=0x7ffff46b6040) at Objects/obmalloc.c:1994 #10 0x00007ffff6a38f55 in PyObject_Free (ptr=<optimized out>) at Objects/obmalloc.c:503 #11 0x00007ffff6a5f27e in unicode_dealloc (unicode=unicode@entry=0x7ffff46b6040) at Objects/unicodeobject.c:1794 #12 0x00007ffff6a352a9 in _Py_Dealloc (op=0x7ffff46b6040) at Objects/object.c:1786 #13 0x000000000063f28b in gdb_Py_DECREF (op=0x7ffff46b6040) at /home/emaisin/src/binutils-gdb/gdb/python/python-internal.h:192 #14 0x000000000063fa33 in gdbpy_ref_policy::decref (ptr=0x7ffff46b6040) at /home/emaisin/src/binutils-gdb/gdb/python/py-ref.h:35 #15 0x000000000063fa77 in gdb::ref_ptr<_object, gdbpy_ref_policy>::~ref_ptr (this=0x7fffffffcdf0, __in_chrg=<optimized out>) at /home/emaisin/src/binutils-gdb/gdb/common/gdb_ref_ptr.h:91 #16 0x000000000064d8b8 in fnpy_call (gdbarch=0x2b50010, language=0x115d2c0 <c_language_defn>, cookie=0x7ffff46b7468, argc=1, argv=0x7fffffffcf48) at /home/emaisin/src/binutils-gdb/gdb/python/py-function.c:145 The fix is to place the gdbpy_enter first in the function.

Fix python-interactive with Python 3.6 New in v2: - Define PyMem_RawMalloc as PyMem_Malloc for Python < 3.4 and use PyMem_RawMalloc in the code. Since Python 3.4, the callback installed in PyOS_ReadlineFunctionPointer should return a value allocated with PyMem_RawMalloc instead of PyMem_Malloc. The reason is that PyMem_Malloc must be called with the Python Global Interpreter Lock (GIL) held, which is not the case in the context where this function is called. PyMem_RawMalloc was introduced for cases like this. In Python 3.6, it looks like they added an assert to verify that PyMem_Malloc was not called without the GIL. The consequence is that typing anything in the python-interactive mode of gdb crashes the process. The same behavior was observed with the official package on Arch Linux as well as with a manual Python build on Ubuntu 14.04. This is what is shown with a debug build of Python 3.6 (the error with a non-debug build is far less clear): (gdb) pi >>> print(1) Fatal Python error: Python memory allocator called without holding the GIL Current thread 0x00007f1459af8780 (most recent call first): [1] 21326 abort ./gdb and the backtrace: #0 0x00007ffff618bc37 in raise () from /lib/x86_64-linux-gnu/libc.so.6 #1 0x00007ffff618f028 in abort () from /lib/x86_64-linux-gnu/libc.so.6 #2 0x00007ffff6b104d6 in Py_FatalError (msg=msg@entry=0x7ffff6ba15b8 "Python memory allocator called without holding the GIL") at Python/pylifecycle.c:1457 #3 0x00007ffff6a37a68 in _PyMem_DebugCheckGIL () at Objects/obmalloc.c:1972 #4 0x00007ffff6a3804e in _PyMem_DebugFree (ctx=0x7ffff6e65290 <_PyMem_Debug+48>, ptr=0x24f8830) at Objects/obmalloc.c:1994 #5 0x00007ffff6a38e1d in PyMem_Free (ptr=<optimized out>) at Objects/obmalloc.c:442 #6 0x00007ffff6b866c6 in _PyFaulthandler_Fini () at ./Modules/faulthandler.c:1369 #7 0x00007ffff6b104bd in Py_FatalError (msg=msg@entry=0x7ffff6ba15b8 "Python memory allocator called without holding the GIL") at Python/pylifecycle.c:1431 #8 0x00007ffff6a37a68 in _PyMem_DebugCheckGIL () at Objects/obmalloc.c:1972 #9 0x00007ffff6a37aa3 in _PyMem_DebugMalloc (ctx=0x7ffff6e65290 <_PyMem_Debug+48>, nbytes=5) at Objects/obmalloc.c:1980 #10 0x00007ffff6a38d91 in PyMem_Malloc (size=<optimized out>) at Objects/obmalloc.c:418 #11 0x000000000064dbe2 in gdbpy_readline_wrapper (sys_stdin=0x7ffff6514640 <_IO_2_1_stdin_>, sys_stdout=0x7ffff6514400 <_IO_2_1_stdout_>, prompt=0x7ffff4d4f7d0 ">>> ") at /home/emaisin/src/binutils-gdb/gdb/python/py-gdb-readline.c:75 The documentation is very clear about it [1] and it was also mentioned in the "What's New In Python 3.4" page [2].

Add command to erase all flash memory regions Changes in v4: - Replaced phex call with hex_string. Changes in v3: - Addressed comments by Pedro. - Output of memory region size now in hex format. - Misc formatting fixups. - Addressed Simon's comments on formatting. - Adjusted command text in the manual entry. - Fixed up ChangeLog. - Renamed flash_erase_all_command to flash_erase_command. Changes in v2: - Added NEWS entry. - Fixed long lines. - Address printing with paddress. Years ago we contributed flash programming patches upstream. The following patch is a leftover one that complements that functionality by adding a new command to erase all reported flash memory blocks. The command is most useful when we're dealing with flash-enabled targets (mostly bare-metal) and we need to reset the board for some reason. The wiping out of flash memory regions should help the target come up with a known clean state from which the user can load a new image and resume debugging. It is convenient enough to do this from the debugger, and there is also an MI command to expose this functionality to the IDE's. gdb/doc/ChangeLog: 2017-01-20 Mike Wrighton <mike_wrighton@codesourcery.com> Luis Machado <lgustavo@codesourcery.com> * gdb.texinfo (-target-flash-erase): New MI command description.

Use class to manage BFD reference counts 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.

Change event code to use gdbpy_ref This changes the event code in the Python layer to use gdbpy_ref, simplifying the logic in many places. It also changes evpy_emit_event not to steal a reference to its argument. This is simpler to do now that gdbpy_ref is in use; it's also a reasonable cleanup in its own right. While doing this I realized that evpy_emit_event should not be calling gdbpy_print_stack (all the outermost callers do this if needed), so I removed this as well. 2017-01-10 Tom Tromey <tom@tromey.com> * python/py-threadevent.c (create_thread_event_object): Use gdbpy_ref. * python/py-stopevent.c (create_stop_event_object): Simplify.
