2024-04-23gdb: change return type of check_quit_flag to boolSimon Marchi1-1/+1
Change the return type of the check_quit_flag function to bool. Update a few related spots. Change-Id: I9d3a15d3f8651efb02c7d211f06222a592bd4184 Approved-By: Tom Tromey <tom@tromey.com>
2024-04-23gdb: move declarations of check_quit_flag and set_quit_flag to extension.hSimon Marchi1-0/+30
Move them out of defs.h, to extension.h, since the implementations are in extension.c. Change-Id: Ie7321468bd7fecc684d70b09f72c3ee8ac75d8f4 Approved-By: Tom Tromey <tom@tromey.com>
2024-04-22gdb: don't include hashtab.h in defs.hSimon Marchi1-0/+1
Nothing in defs.h actually uses this. Add some includes for some spots using things from hashtab.h. Note that if the GDB build doesn't use libxxhash, hashtab.h is included by gdbsupport/common-utils.h, so all files still see hashtab.h. It puzzled me for some time why I didn't see build failures in my build (which didn't use libxxhash) but the buildbot gave build failures (it uses libxxhash).

2024-02-27Add extension_language_ops::shutdownTom Tromey1-0/+3
Right now, Python is shut down via a final cleanup. However, it seems to me that it is better for extension languages to be shut down explicitly, after all the ordinary final cleanups are run. The main reason for this is that a subsequent patch adds another case like finalize_values; and rather than add a series of workarounds for Python shutdown, it seemed better to let these be done via final cleanups, and then have Python shutdown itself be the special case.
2024-02-20gdb: pass frames as `const frame_info_ptr &`Simon Marchi1-1/+1
We currently pass frames to function by value, as `frame_info_ptr`. This is somewhat expensive: - the size of `frame_info_ptr` is 64 bytes, which is a bit big to pass by value - the constructors and destructor link/unlink the object in the global `frame_info_ptr::frame_list` list. This is an `intrusive_list`, so it's not so bad: it's just assigning a few points, there's no memory allocation as if it was `std::list`, but still it's useless to do that over and over. As suggested by Tom Tromey, change many function signatures to accept `const frame_info_ptr &` instead of `frame_info_ptr`. Some functions reassign their `frame_info_ptr` parameter, like: void the_func (frame_info_ptr frame) { for (; frame != nullptr; frame = get_prev_frame (frame)) { ... } } I wondered what to do about them, do I leave them as-is or change them (and need to introduce a separate local variable that can be re-assigned). I opted for the later for consistency. It might not be clear why some functions take `const frame_info_ptr &` while others take `frame_info_ptr`. Also, if a function took a `frame_info_ptr` because it did re-assign its parameter, I doubt that we would think to change it to `const frame_info_ptr &` should the implementation change such that it doesn't need to take `frame_info_ptr` anymore. It seems better to have a simple rule and apply it everywhere. Change-Id: I59d10addef687d157f82ccf4d54f5dde9a963fd0 Approved-By: Andrew Burgess <aburgess@redhat.com>
2024-02-07Fix raw-frame-arguments in combination with frame-filtersHannes Domani1-0/+4
Currently, if frame-filters are active, raw-values is used instead of raw-frame-arguments to decide if a pretty-printer should be invoked for frame arguments in a backtrace. In this example, "super struct" is the output of the pretty-printer: (gdb) disable frame-filter global BasicFrameFilter (gdb) bt #0 foo (x=42, ss=super struct = {...}) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47 #1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57 If no frame-filter is active, then the raw-values print option does not affect the backtrace output: (gdb) set print raw-values on (gdb) bt #0 foo (x=42, ss=super struct = {...}) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47 #1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57 (gdb) set print raw-values off Instead, the raw-frame-arguments option disables the pretty-printer in the backtrace: (gdb) bt -raw-frame-arguments on #0 foo (x=42, ss=...) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47 #1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57 But if a frame-filter is active, the same rules don't apply. The option raw-frame-arguments is ignored, but raw-values decides if the pretty-printer is used: (gdb) enable frame-filter global BasicFrameFilter (gdb) bt #0 foo (x=42, ss=super struct = {...}) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47 #1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57 (gdb) set print raw-values on (gdb) bt #0 foo (x=42, ss=...) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47 #1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57 (gdb) set print raw-values off (gdb) bt -raw-frame-arguments on #0 foo (x=42, ss=super struct = {...}) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47 #1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57 So this adds the PRINT_RAW_FRAME_ARGUMENTS flag to frame_filter_flag, which is then used in the frame-filter to override the raw flag in enumerate_args. Then the output is the same if a frame-filter is active, the pretty-printer for backtraces is only disabled with the raw-frame-arguments option: (gdb) enable frame-filter global BasicFrameFilter (gdb) bt #0 foo (x=42, ss=super struct = {...}) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47 #1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57 (gdb) set print raw-values on (gdb) bt #0 foo (x=42, ss=super struct = {...}) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47 #1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57 (gdb) set print raw-values off (gdb) bt -raw-frame-arguments on #0 foo (x=42, ss=...) at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:47 #1 0x004016aa in main () at C:/src/repos/gdb-testsuite/gdb/testsuite/gdb.python/py-frame-args.c:57 Co-Authored-By: Andrew Burgess <aburgess@redhat.com> Approved-By: Tom Tromey <tom@tromey.com>
2024-01-12Update copyright year range in header of all files managed by GDBAndrew Burgess1-1/+1
This commit is the result of the following actions: - Running gdb/copyright.py to update all of the copyright headers to include 2024, - Manually updating a few files the copyright.py script told me to update, these files had copyright headers embedded within the file, - Regenerating gdbsupport/Makefile.in to refresh it's copyright date, - Using grep to find other files that still mentioned 2023. If these files were updated last year from 2022 to 2023 then I've updated them this year to 2024. I'm sure I've probably missed some dates. Feel free to fix them up as you spot them.
2023-11-21gdb: Replace gdb::optional with std::optionalLancelot Six1-4/+4
Since GDB now requires C++17, we don't need the internally maintained gdb::optional implementation. This patch does the following replacing: - gdb::optional -> std::optional - gdb::in_place -> std::in_place - #include "gdbsupport/gdb_optional.h" -> #include <optional> This change has mostly been done automatically. One exception is gdbsupport/thread-pool.* which did not use the gdb:: prefix as it already lives in the gdb namespace.

2023-11-14gdb: add an extension language hook for missing debug infoAndrew Burgess1-0/+62
This commit adds a new extension_language_ops hook which allows an extension to handle the case where GDB can't find a separate debug information file for a particular objfile. This commit doesn't actually implement the hook for any of GDB's extension languages, the next commit will do that. This commit just adds support for the hook to extension-priv.h and extension.[ch], and then reworks symfile-debug.c to call the hook. Right now the hook will always return its default value, which means GDB should do nothing different. As such, there should be no user visible changes after this commit. I'll give a brief description of what the hook does here so that we can understand the changes in symfile-debug.c. The next commit adds a Python implementation for this new hook, and gives a fuller description of the new functionality. Currently, when looking for separate debug information GDB tries three things, in this order: 1. Use the build-id to find the required debug information, 2. Check for .gnu_debuglink section and use that to look up the required debug information, 3. Check with debuginfod to see if it can supply the required information. The new extension_language_ops::handle_missing_debuginfo hook is called if all three steps fail to find any debug information. The hook has three possible return values: a. Nothing, no debug information is found, GDB continues without the debug information for this objfile. This matches the current behaviour of GDB, and is the default if nothing is implementing this new hook, b. Install debug information into a location that step #1 or #2 above would normally check, and then request that GDB repeats steps #1 and #2 in the hope that GDB will now find the debug information. If the debug information is still not found then GDB carries on without the debug information. If the debug information is found the GDB loads it and carries on, c. Return a filename for a file containing the required debug information. GDB loads the contents of this file and carries on. The changes in this commit mostly involve placing the core of objfile::find_and_add_separate_symbol_file into a loop which allows for steps #1 and #2 to be repeated. We take care to ensure that debuginfod is only queried once, the first time through. The assumption is that no extension is going to be able to control the replies from debuginfod, so there's no point making a second request -- and as these requests go over the network, they could potentially be slow. The warnings that find_and_add_separate_symbol_file collects are displayed only once assuming that no debug information is found. If debug information is found, even after the extension has operated, then the warnings are not shown; remember, these are warnings from GDB about failure to find any suitable debug information, so it makes sense to hide these if debug information is found.

2023-02-15Don't throw quit while handling inferior events, part IIPedro Alves1-0/+16
I noticed that if Ctrl-C was typed just while GDB is evaluating a breakpoint condition in the background, and GDB ends up reaching out to the Python interpreter, then the breakpoint condition would still fail, like: c& Continuing. (gdb) Error in testing breakpoint condition: Quit That happens because while evaluating the breakpoint condition, we enter Python, and end up calling PyErr_SetInterrupt (it's called by gdbpy_set_quit_flag, in frame #0): (top-gdb) bt #0 gdbpy_set_quit_flag (extlang=0x558c68f81900 <extension_language_python>) at ../../src/gdb/python/python.c:288 #1 0x0000558c6845f049 in set_quit_flag () at ../../src/gdb/extension.c:785 #2 0x0000558c6845ef98 in set_active_ext_lang (now_active=0x558c68f81900 <extension_language_python>) at ../../src/gdb/extension.c:743 #3 0x0000558c686d3e56 in gdbpy_enter::gdbpy_enter (this=0x7fff2b70bb90, gdbarch=0x558c6ab9eac0, language=0x0) at ../../src/gdb/python/python.c:212 #4 0x0000558c68695d49 in python_on_memory_change (inferior=0x558c6a830b00, addr=0x555555558014, len=4, data=0x558c6af8a610 "") at ../../src/gdb/python/py-inferior.c:146 #5 0x0000558c6823a071 in std::__invoke_impl<void, void (*&)(inferior*, unsigned long, long, unsigned char const*), inferior*, unsigned long, long, unsigned char const*> (__f=@0x558c6a8ecd98: 0x558c68695d01 <python_on_memory_change(inferior*, CORE_ADDR, ssize_t, bfd_byte const*)>) at /usr/include/c++/11/bits/invoke.h:61 #6 0x0000558c68237591 in std::__invoke_r<void, void (*&)(inferior*, unsigned long, long, unsigned char const*), inferior*, unsigned long, long, unsigned char const*> (__fn=@0x558c6a8ecd98: 0x558c68695d01 <python_on_memory_change(inferior*, CORE_ADDR, ssize_t, bfd_byte const*)>) at /usr/include/c++/11/bits/invoke.h:111 #7 0x0000558c68233e64 in std::_Function_handler<void (inferior*, unsigned long, long, unsigned char const*), void (*)(inferior*, unsigned long, long, unsigned char const*)>::_M_invoke(std::_Any_data const&, inferior*&&, unsigned long&&, long&&, unsigned char const*&&) (__functor=..., __args#0=@0x7fff2b70bd40: 0x558c6a830b00, __args#1=@0x7fff2b70bd38: 93824992247828, __args#2=@0x7fff2b70bd30: 4, __args#3=@0x7fff2b70bd28: 0x558c6af8a610 "") at /usr/include/c++/11/bits/std_function.h:290 #8 0x0000558c6830a96e in std::function<void (inferior*, unsigned long, long, unsigned char const*)>::operator()(inferior*, unsigned long, long, unsigned char const*) const (this=0x558c6a8ecd98, __args#0=0x558c6a830b00, __args#1=93824992247828, __args#2=4, __args#3=0x558c6af8a610 "") at /usr/include/c++/11/bits/std_function.h:590 #9 0x0000558c6830a620 in gdb::observers::observable<inferior*, unsigned long, long, unsigned char const*>::notify (this=0x558c690828c0 <gdb::observers::memory_changed>, args#0=0x558c6a830b00, args#1=93824992247828, args#2=4, args#3=0x558c6af8a610 "") at ../../src/gdb/../gdbsupport/observable.h:166 #10 0x0000558c68309d95 in write_memory_with_notification (memaddr=0x555555558014, myaddr=0x558c6af8a610 "", len=4) at ../../src/gdb/corefile.c:363 #11 0x0000558c68904224 in value_assign (toval=0x558c6afce910, fromval=0x558c6afba6c0) at ../../src/gdb/valops.c:1190 #12 0x0000558c681e3869 in expr::assign_operation::evaluate (this=0x558c6af8e150, expect_type=0x0, exp=0x558c6afcfe60, noside=EVAL_NORMAL) at ../../src/gdb/expop.h:1902 #13 0x0000558c68450c89 in expr::logical_or_operation::evaluate (this=0x558c6afab060, expect_type=0x0, exp=0x558c6afcfe60, noside=EVAL_NORMAL) at ../../src/gdb/eval.c:2330 #14 0x0000558c6844a896 in expression::evaluate (this=0x558c6afcfe60, expect_type=0x0, noside=EVAL_NORMAL) at ../../src/gdb/eval.c:110 #15 0x0000558c6844a95e in evaluate_expression (exp=0x558c6afcfe60, expect_type=0x0) at ../../src/gdb/eval.c:124 #16 0x0000558c682061ef in breakpoint_cond_eval (exp=0x558c6afcfe60) at ../../src/gdb/breakpoint.c:4971 ...

2022-06-15gdb: add extension language print_insn hookAndrew Burgess1-0/+10
This commit is setup for the next commit. In the next commit I will add a Python API to intercept the print_insn calls within GDB, each print_insn call is responsible for disassembling, and printing one instruction. After the next commit it will be possible for a user to write Python code that either wraps around the existing disassembler, or even, in extreme situations, entirely replaces the existing disassembler. This commit does not add any new Python API. What this commit does is put the extension language framework in place for a print_insn hook. There's a new callback added to 'struct extension_language_ops', which is then filled in with nullptr for Python and Guile. Finally, in the disassembler, the code is restructured so that the new extension language function ext_lang_print_insn is called before we delegate to gdbarch_print_insn. After this, the next commit can focus entirely on providing a Python implementation of the new print_insn callback. There should be no user visible change after this commit.
2022-02-14gdb: use python to colorize disassembler outputAndrew Burgess1-0/+8
This commit adds styling support to the disassembler output, as such two new commands are added to GDB: set style disassembler enabled on|off show style disassembler enabled In this commit I make use of the Python Pygments package to provide the styling. I did investigate making use of libsource-highlight, however, I found the highlighting results to be inferior to those of Pygments; only some mnemonics were highlighted, and highlighting of register names such as r9d and r8d (on x86-64) was incorrect. To enable disassembler highlighting via Pygments, I've added a new extension language hook, which is then implemented for Python. This hook is very similar to the existing hook for source code colorization. One possibly odd choice I made with the new hook is to pass a gdb.Architecture through, even though this is currently unused. The reason this argument is not used is that, currently, styling is performed identically for all architectures. However, even though the Python function used to perform styling of disassembly output is not part of any documented API, I don't want to close the door on a user overriding this function to provide architecture specific styling. To do this, the user would inevitably require access to the gdb.Architecture, and so I decided to add this field now. The styling is applied within gdb_disassembler::print_insn, to achieve this, gdb_disassembler now writes its output into a temporary buffer, styling is then applied to the contents of this buffer. Finally the gdb_disassembler buffer is copied out to its final destination stream. There's a new test to check that the disassembler output includes some escape sequences, though I don't check for specific colours; the precise colors will depend on which instructions are in the disassembler output, and, I guess, how pygments is configured. The only negative change with this commit is how we currently style addresses in GDB. Currently, when the disassembler wants to print an address, we call back into GDB, and GDB prints the address value using the `address` styling, and the symbol name using `function` styling. After this commit, if pygments is used, then all disassembler styling is done through pygments, and this include the address and symbol name parts of the disassembler output. I don't know how much of an issue this will be for people. There's already some precedent for this in GDB when we look at source styling. For example, function names in styled source listings are not styled using the `function` style, but instead, either GNU Source Highlight, or pygments gets to decide how the function name should be styled. If the Python pygments library is not present then GDB will continue to behave as it always has, the disassembler output is mostly unstyled, but the address and symbols are styled using the `address` and `function` styles, as they are today. However, if the user does `set style disassembler enabled off`, then all disassembler styling is switched off. This obviously covers the use of pygments, but also includes the minimal styling done by GDB when pygments is not available.

2021-10-19[gdb/testsuite] Reimplement gdb.gdb/python-interrupts.exp as unittestTom de Vries1-0/+6
The test-case gdb.gdb/python-interrupts.exp: - runs to captured_command_loop - sets a breakpoint at set_active_ext_lang - calls a python command - verifies the command triggers the breakpoint - sends a signal and verifies the result The test-case is fragile, because (f.i. with -flto) it cannot be guaranteed that captured_command_loop and set_active_ext_lang are available for setting breakpoints. Reimplement the test-case as unittest, using: - execute_command_to_string to capture the output - try/catch to catch the "Error while executing Python code" exception - a new hook selftests::hook_set_active_ext_lang to raise the signal Tested on x86_64-linux.

2020-03-13Change extension language pretty-printers to use value APITom Tromey1-4/+2
This changes the extension language pretty-printers to use the value API. Note that new functions were needed, for both Guile and Python. Currently both languages always wrap values by removing the values from the value chain. This makes sense to avoid strange behavior with watchpoints, and to avoid excessive memory use. However, when printing, it's important to leave the passed-in value untouched, in case pretty-printing does nothing -- that way the caller can still access it. gdb/ChangeLog 2020-03-13 Tom Tromey <tom@tromey.com> * valprint.c (do_val_print): Update. * python/python-internal.h (gdbpy_apply_val_pretty_printer): Take a struct value.

2020-01-21Allow use of Pygments to colorize source codeTom Tromey1-0/+9
While GNU Source Highlight is good, it's also difficult to build and distribute. For one thing, it needs Boost. For another, it has an unusual configuration and installation setup. Pygments, a Python library, doesn't suffer from these issues, and so I thought it would be a reasonable fallback. This patch implements this idea. GNU Source Highlight is preferred, but if it is unavailable (or fails), the extension languages are tried. This patch also implements support for Pygments. Something similar could be done for Guile, using: https://dthompson.us/projects/guile-syntax-highlight.html However, I don't know enough about Guile internals to make this happen, so I have not done it here. gdb/ChangeLog 2020-01-21 Tom Tromey <tromey@adacore.com> * source-cache.c (source_cache::ensure): Call ext_lang_colorize. * python/python.c (python_extension_ops): Update.

2019-07-29Implement 'set print frame-info|frame-arguments presence'.Philippe Waroquiers1-1/+4
New settings allow to better control what frame information is printed. 'set print frame-info' allows to override the default frame information printed when a GDB command prints a frame. The backtrace command has a new option -frame-info to override this global setting. It is now possible to have very short frame information by using the new 'set print frame-arguments presence' and 'set print frame-info short-location'. Combined with 'set print address off', a backtrace will only show the essential information to see the function call chain, e.g.: (gdb) set print address off (gdb) set print frame-arguments presence (gdb) set print frame-info short-location (gdb) bt #0 break_me () #1 call_me (...) #2 main () (gdb) This is handy in particular for big backtraces with functions having many arguments. Python frame filter printing logic has been updated to respect the new setting in non MI mode. Also, the default frame information printed was inconsistent when backtrace was printing the frame information itself, or when the python frame filtering code was printing the frame information. This patch changes the default of python frame filtering to have a consistent behaviour regarding printed frame-information, whatever the presence/activity/matches of python filters. 2019-07-29 Philippe Waroquiers <philippe.waroquiers@skynet.be> * frame.h (enum print_what): New value 'SHORT_LOCATION', update comments.

2019-07-09Rename common to gdbsupportTom Tromey1-2/+2
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty.

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
2018-11-21invoke_xmethod & array_viewPedro Alves1-17/+15
This replaces more pointer+length with gdb::array_view. This time, around invoke_xmethod, and then propagating the fallout around, which inevitably leaks to the overload resolution code. There are several places in the code that want to grab a slice of an array, by advancing the array pointer, and decreasing the length pointer. This patch introduces a pair of new gdb::array_view::slice(...) methods to make that convenient and clear.

2018-05-17Initialize py_type_printers in ext_lang_type_printersTom Tromey1-1/+1
When running gdb in the build directory without passing --data-directory, I noticed I could provoke a crash by: $ ./gdb -nx ./gdb (gdb) ptype/o struct dwarf2_per_objfile ... and then trying to "q" out at the pagination prompt. valgrind complained about an uninitialized use of py_type_printers. Initializing this member fixes the bug. I believe this bug can occur even when the gdb Python libraries are available, for example if get_type_recognizers fails. Tested by hand on x86-64 Fedora 26. No test case because it seemed difficult to guarantee failures. gdb/ChangeLog 2018-05-17 Tom Tromey <tom@tromey.com> * extension.h (struct ext_lang_type_printers) <py_type_printers>: Initialize.

2018-02-26Make "bt N" print correct number of frames when using a frame filterTom Tromey1-0/+3
PR python/16497 notes that using "bt" with a positive argument prints the wrong number of frames when a frame filter is in use. Also, in this case, the non-frame-filter path will print a message about "More stack frames" when there are more; but this is not done in the frame-filter case. The first problem is that backtrace_command_1 passes the wrong value to apply_ext_lang_frame_filter -- that function takes the final frame's number as an argument, but backtrace_command_1 passes the count, which is off by one. The solution to the second problem is to have the C stack-printing code stop at the correct number of frames and then print the message. Tested using the buildbot.

2018-01-07Remove xmethod_worker::cloneSimon Marchi1-7/+0
I think that the clone method of xmethod_worker can be removed. It is only used in find_overload_match, to clone an xmethod we want to keep. Instead, we can just std::move it out of the vector and into value_from_xmethod. value_from_xmethod creates a value that will own the xmethod_worker from that point. Other xmethod_workers left in the vector will get destroyed when the vector gets destroyed, but the chosen one will keep living inside the value struct. gdb/ChangeLog: * extension.h (struct xmethod_worker) <clone>: Remove. * python/py-xmethods.c (struct python_xmethod_worker) <clone>: Remove. (python_xmethod_worker::clone): Remove. * valops.c (find_overload_match): Use std::move instead of clone.
2018-01-07C++ify xmethod_worker, get rid of VEC(xmethod_worker_ptr)Simon Marchi1-31/+77
The initial goal of this patch was to remove the usage of VEC(xmethod_worker_ptr) and corresponding cleanups. I ended up having to C++ify the xmethod_worker code, to be able to have xmethod_workers free their data in destructors, and therefore be able to use vectors of xmethod_worker unique_ptr. The operations in extension_language_ops that act on one instance of xmethod_worker (get result type, get args type, invoke) are transformed to methods of xmethod_worker. xmethod_worker becomes an abstract base class with virtual pure methods which python_xmethod_worker implements. The only xmethod-related operation left in extension_language_ops is get_matching_xmethod_workers, which returns a list of xmethod_workers. The changes are relatively straightforward, but here are some notes on things that may raise eyebrows: - I was not really comfortable with the value_of_xmethod function. At first it looks like a simple getter, so I considered making it a method of xmethod_worker. But actually it creates a value and transfers the ownership of the xmethod_worker to it. It would be a bit weird and error-prone if calling a method on an object silently removed the ownership of the object from the caller. To reflect the behavior more accurately, I renamed it to value_from_xmethod and made it accept an rvalue-reference (so the caller knows it gives away the ownership). I noticed the backlink from xmethod_worker to its owning value was not used, so I removed it. - Some code, like get_matching_xmethod_workers, made each callee fill a new vector, which was then merged in the result vector. I think it's safe if we always pass the same vector around, and each implementation just appends to it. - The clone operation does not seem particularly useful, it is removed in the following patch. gdb/ChangeLog: * extension-priv.h (enum ext_lang_rc): Remove, move to extension.h.
