gdb: give deprecated command warning for aliases with a prefix
I noticed that deprecated aliases that have a prefix don't give a deprecated command warning. For example looking in mi/mi-main.c we see this: c = add_alias_cmd ("target-async", "mi-async", class_run, 0, &setlist); deprecate_cmd (c, "set mi-async"); c = add_alias_cmd ("target-async", "mi-async", class_run, 0, &showlist); deprecate_cmd (c, "show mi-async"); So both 'set target-async' and 'show target-async' are deprecated and should be giving a warning, however, in use we see no warning given. This is a consequence of how the code that should give this warning (deprecated_cmd_warning) performs a second command lookup in order to distinguish between aliases and real commands, and that the code that calls this (lookup_cmd_1) strips off prefix commands as it calls itself recursively. As a result when we are considering an alias like 'set target-async' we first enter lookup_cmd_1 with text = "set target-async", we spot the 'set' command prefix and then recursively call lookup_cmd_1 with text = "target-async". We spot that 'target-async' is a known alias but that it is deprecated, and so call deprecated_cmd_warning passing in the value of text, which remember is now "target-async". In deprecated_cmd_warning we again perform a command lookup starting from the top-level cmdlist, but now we're trying to find just "target-async", this fails (as this command requires the 'set' prefix, and so no warning is given. I resolved this issue by passing a command list to the function deprecated_cmd_warning, this is the list in which the command can be found. A new test is added to cover this case. However, there is an additional problem which will be addressed in a subsequent patch. Consider this GDB session: (gdb) define set xxx_yyy Type commands for definition of "set xxx_yyy". End with a line saying just "end". >echo in set xxx_yyy command\n >end (gdb) alias set qqq_aaa=set xxx_yyy (gdb) maintenance deprecate set qqq_aaa (gdb) set qqq_aaa Warning: 'qqq_aaa', an alias for the command 'xxx_yyy' is deprecated. No alternative known. in set xxx_yyy command (gdb) Notice the warning mentions 'qqq_aaa' and 'xxx_yyy', I consider this to be wrong. I think the proper warning should read: (gdb) set qqq_aaa Warning: 'set qqq_aaa', an alias for the command 'set xxx_yyy' is deprecated. No alternative known. With the 'set' prefixes added. A later patch will resolve this issue. gdb/ChangeLog: PR cli/15104 * cli/cli-decode.c (lookup_cmd_1): Pass command list to deprecated_cmd_warning.

gdb: don't warn about deprecated aliases during tab completion
Consider this gdb session, where on line #3 tab completion is used: (gdb) alias xxx_yyy_zzz=break (gdb) maint deprecate xxx_yyy_zzz (gdb) xxx_yyy_<TAB> The third line then updates to look like this: (gdb) xxx_yyy_Warning: 'xxx_yyy_zzz', an alias for the command 'break' is deprecated. No alternative known. zzz What's happened is during tab completion the alias has been resolved to the actual command being aliased, and at this stage the warning is issued. Clearly this is not what we want during tab completion. In this commit I add a new parameter to the lookup function, a boolean that indicates if the lookup is being done as part of completion. This flag is used to suppress the warning. Now we get the expected behaviour, the alias completes without any warning, but the warning is still given once the user executes the alias. gdb/ChangeLog: * cli/cli-decode.c (lookup_cmd_1): Move header comment into command.h, add extra parameter, and use this to guard giving a warning. * command.h (lookup_cmd_1): Add comment from cli/cli-decode.c, include argument names in declaration, add new argument. * completer.c (complete_line_internal_1): Remove unneeded brackets, pass extra argument to lookup_cmd_1. gdb/testsuite/ChangeLog: * gdb.base/completion.exp: Add additional tests. |

Remove "cmd_type" function
The cmd_type function only has a single caller, which is in the CLI implementation code. This patch removes the function, and moves the cmd_types enum definition from command.h to cli-decode.h, fixing an 18 year old FIXME. gdb/ChangeLog 2020-06-28 Tom Tromey <tom@tromey.com> * command.h (cmd_types): Remove. (cmd_type): Don't declare. * cli/cli-decode.h (enum cmd_types): Uncomment. No longer a typedef. * cli/cli-cmds.c (setting_cmd): Use cmd->type directly. * cli/cli-decode.c (cmd_type): Remove. |

default-args: allow to define default arguments for aliases
Currently, a user can define an alias, but cannot have default arguments for this alias. This patch modifies the 'alias' command so that default args can be provided. (gdb) h alias Define a new command that is an alias of an existing command. Usage: alias [-a] [--] ALIAS = COMMAND [DEFAULT-ARGS...] ALIAS is the name of the alias command to create. COMMAND is the command being aliased to. Options: -a Specify that ALIAS is an abbreviation of COMMAND. Abbreviations are not used in command completion.. GDB will automatically prepend the provided DEFAULT-ARGS to the list of arguments explicitly provided when using ALIAS. Use "help aliases" to list all user defined aliases and their default args. Examples: Make "spe" an alias of "set print elements": alias spe set print elements Make "elms" an alias of "elements" in the "set print" command: alias -a set print elms set print elements Make "btf" an alias of "backtrace -full -past-entry -past-main" : alias btf = backtrace -full -past-entry -past-main Make "wLapPeu" an alias of 2 nested "with": alias wLapPeu = with language pascal -- with print elements unlimited -- (gdb) The way 'default-args' is implemented makes it trivial to set default args also for GDB commands (such as "backtrace") and for GDB pre-defined aliases (such as "bt"). It was however deemed better to not allow to define default arguments for pre-defined commands and aliases, to avoid users believing that e.g. default args for "backtrace" would apply to "bt". If needed, default-args could be allowed for GDB predefined commands and aliases by adding a command 'set default-args GDB_COMMAND_OR_PREDEFINED_ALIAS [DEFAULT-ARGS...]'. * 'alias' command now has a completer that helps to complete: - ALIAS (if the user defines an alias after a prefix), - the aliased COMMAND - the possible options for the aliased COMMAND. * Help and apropos commands show the definitions of the aliases that have default arguments, e.g. (gdb) help backtrace backtrace, btf, where, bt alias btf = backtrace -full -past-entry -past-main Print backtrace of all stack frames, or innermost COUNT frames. Usage: backtrace [OPTION]... [QUALIFIER]... [COUNT | -COUNT] Options: -entry-values no|only|preferred|if-needed|both|compact|default Set printing of function arguments at function entry. ... gdb/ChangeLog 2020-06-22 Philippe Waroquiers <philippe.waroquiers@skynet.be> * cli/cli-cmds.c (lookup_cmd_for_default_args) (alias_command_completer) (make_alias_options_def_group): New functions.

Ensure class_alias is only used for user-defined aliases.
This commit finally does the (small) change that started this patch series. It ensures that the class_alias is only used for user-defined aliases. So, the few GDB pre-defined aliases that were using the 'class_alias' class are now using a real help class, typically the class of the aliased command. gdb/ChangeLog 2020-05-15 Philippe Waroquiers <philippe.waroquiers@skynet.be> * command.h (enum command_class): Improve comments, document that class_alias is for user-defined aliases, give the class name for each class, remove unused class_xdb. * cli/cli-decode.c (add_com_alias): Document THECLASS intended usage. * breakpoint.c (_initialize_breakpoint): Replace class_alias by a precise class. * infcmd.c (_initialize_infcmd): Likewise. * reverse.c (_initialize_reverse): Likewise. * stack.c (_initialize_stack): Likewise. * symfile.c (_initialize_symfile): Likewise. * tracepoint.c (_initialize_tracepoint): Likewise. gdb/testsuite/ChangeLog 2020-05-15 Philippe Waroquiers <philippe.waroquiers@skynet.be> * gdb.base/alias.exp: Verify 'help aliases' shows user defined aliases. |

Fix inconsistent output of prefix and bugs in 'show' command
cmd_show_list function implements the 'show' command. cmd_show_list output is inconsistent: it sometimes shows a prefix and sometimes does not. For example, in the below, you see that there is a prefix before each value, except for 'enabled'. (gdb) show style style address background: The "address" style background color is: none style address foreground: The "address" style foreground color is: blue style address intensity: The "address" style display intensity is: normal enabled: CLI output styling is enabled. style filename background: The "filename" style background color is: none ... There are other inconsistencies or bugs e.g. in the below we see twice insn-number-max, once with a prefix and once without prefix : last line, just before the value of instruction-history-size which is itself without prefix. (gdb) show record record btrace bts buffer-size: The record/replay bts buffer size is 65536. record btrace cpu: btrace cpu is 'auto'. record btrace pt buffer-size: The record/replay pt buffer size is 16384. record btrace replay-memory-access: Replay memory access is read-only. record full insn-number-max: Record/replay buffer limit is 200000. record full memory-query: Whether query if PREC cannot record memory change of next instruction is off. record full stop-at-limit: Whether record/replay stops when record/replay buffer becomes full is on. function-call-history-size: Number of functions to print in "record function-call-history" is 10. insn-number-max: instruction-history-size: Number of instructions to print in "record instruction-history" is 10. (gdb) Also, some values are output several times due to some aliases, so avoid outputting duplicated values by skipping all aliases. Now that the command structure has a correct 'back-pointer' from a command to its prefix command, we can simplify cmd_show_list by removing its prefix argument and at the same time fix the output inconsistencies and bugs. gdb/ChangeLog 2020-05-15 Philippe Waroquiers <philippe.waroquiers@skynet.be> * cli/cli-setshow.h (cmd_show_list): Remove prefix argument. * cli/cli-decode.c (do_show_prefix_cmd): Likewise. * command.h (cmd_show_list): Likewise. * dwarf2/index-cache.c (show_index_cache_command): Likewise. * cli/cli-setshow.c (cmd_show_list): Use the prefix to produce the output. Skip aliases. gdb/testsuite/ChangeLog 2020-05-15 Philippe Waroquiers <philippe.waroquiers@skynet.be> * gdb.base/default.exp: Update output following fixes. |

Replace most calls to help_list and cmd_show_list
Currently there are many prefix commands that do nothing but call either help_list or cmd_show_list. I happened to notice that one such call, for "set print type", used the wrong command list parameter, causing incorrect output. Rather than fix this bug in isolation, I decided to eliminate this possibility by adding two new ways to add prefix commands, which simply route the call to help_list or cmd_show_list, as appropriate. This makes it impossible for a mismatch to occur. In some cases, a bit of output was removed; however, I don't think this output in general was very useful. It seemed redundant with what's already printed by help_list. A representative example is this hunk, removed from ada-lang.c: - printf_unfiltered (_(\ -"\"set ada\" must be followed by the name of a setting.\n")); This simplified the CLI style set/show commands quite a bit, and allowed the deletion of a macro. This also cleans up some unusual code in windows-tdep.c. Tested on x86-64 Fedora 30. Note that I have no way to build the go32-nat.c change. gdb/ChangeLog 2020-04-17 Tom Tromey <tromey@adacore.com> * auto-load.c (show_auto_load_cmd): Remove.

Rename common to gdbsupport
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. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

Introduce the "with" command
( See original discussion and prototype here: https://sourceware.org/ml/gdb-patches/2019-05/msg00570.html ) (gdb) help with Temporarily set SETTING to VALUE, run COMMAND, and restore SETTING. Usage: with SETTING [VALUE] [-- COMMAND] Usage: w SETTING [VALUE] [-- COMMAND] With no COMMAND, repeats the last executed command. SETTING is any setting you can change with the "set" subcommands. E.g.: with language pascal -- print obj with print elements unlimited -- print obj As can be seen above, the "with" command is just like "set", but instead of setting the setting permanently, it sets the setting, runs a command and then restores the setting. (gdb) p g_s $1 = {a = 1, b = 2, c = 3} (gdb) with language ada -- print g_s $2 = (a => 1, b => 2, c => 3) Warning: the current language does not match this frame. (gdb) show language The current source language is "auto; currently c". (gdb) with print elements 100 -- with print object on -- print 1 $3 = 1 You can shorten things a bit though, as long as unambiguous. So this: (gdb) with print elements 100 -- with print object off -- print 1 is the same as: (gdb) w p el 100 -- w p o 0 -- p 1 Note that the patch adds a "w" alias for "with", as "w" is not currently taken: (gdb) w Ambiguous command "w": watch, wh, whatis, where, while, while-stepping, winheight, ws. Let me know if you'd prefer to reserve "w" for one of the other commands above. IMHO, this command will end up being used frequently enough that it deserves the "w" shorthand. A nice feature is that this is fully integrated with TAB-completion: (gdb) with p[TAB] pagination print prompt python (gdb) with print [TAB] address max-depth static-members array max-symbolic-offset symbol array-indexes null-stop symbol-filename asm-demangle object symbol-loading demangle pascal_static-members thread-events elements pretty type entry-values raw union frame-arguments repeats vtbl inferior-events sevenbit-strings (gdb) with print [TAB] (gdb) with print elements unlimited -- thread apply all -[TAB] -ascending -c -q -s (gdb) with print elements unlimited -- print -[TAB] -address -max-depth -repeats -vtbl -array -null-stop -static-members -array-indexes -object -symbol -elements -pretty -union The main advantage of this new command compared to command options, like the new "print -OPT", is that this command works with any setting, and, it works nicely when you want to override a setting while running a user-defined command, like: (gdb) with print pretty -- usercmd The disadvantage is that it isn't as compact or easy to type. I think of command options and this command as complementary. I think that even with this new command, it makes sense to continue developing the command options in the direction of exposing most-oft-used settings as command options. Inspired by Philippe's "/" command proposal, if no command is specified, then the last command is re-invoked, under the overridden setting: (gdb) p g_s $1 = {a = 1, b = 2, c = 3} (gdb) with language ada $2 = (a => 1, b => 2, c => 3) Warning: the current language does not match this frame. Note: "with" requires "--" to separate the setting from the command. It might be possible to do without that, but, I haven't tried it yet, and I think that this can go in without it. We can always downgrade to making "--" optional if we manage to make it work. On to the patch itself, the implementation of the command is simpler than one might expect. A few details: - I factored out a bit from pipe_command into repeat_previous directly, because otherwise I'd need to copy&paste the same code and same error message in the with command. - The parse_cli_var_uinteger / parse_cli_var_zuinteger_unlimited / do_set_command changes are necessary since we can now pass an empty string as argument. - do_show_command was split in two, as a FIXME comment suggests, but for a different reason: we need to get a string version of a "set" command's value, and we already had code for that in do_show_command. That code is now factored out to the new get_setshow_command_value_string function. - There's a new "maint with" command added too: (gdb) help maint with Like "with", but works with "maintenance set" variables. Usage: maintenance with SETTING [VALUE] [-- COMMAND] With no COMMAND, repeats the last executed command. SETTING is any setting you can change with the "maintenance set" subcommands. "with" and "maint with" share 99% of the implementation. This might be useful on its own, but it's also useful for testing, since with this, we can use the "maint set/show test-settings" settings for exercising the "with" machinery with all the command type variants (all enum var_types). This is done in the new gdb/base/with.exp testcase. The documentation bits are originally based on Philippe's docs for the "/" command, hence the attribution in the ChangeLog. gdb/ChangeLog: 2019-07-03 Pedro Alves <palves@redhat.com> * NEWS (New commands): Mention "with" and "maint with". * cli/cli-cmds.c (with_command_1, with_command_completer_1) (with_command, with_command_completer): New.

A following patch will introduce options for the "backtrace" command, based on some "set print" and "set backtrace" settings. There's one setting in particular that is a bit annoying if we want to describe the backtrace options and the settings commands using the same data structures: "set print raw frame-arguments" The problem is that space between "raw" and "frame-arguments". Calling the option "bt -raw frame-arguments" would be odd. So I'm calling the option "bt -raw-frame-arguments" instead. And for consistency, this patch renames the set/show commands to: "set print raw-frame-arguments" "show print raw-frame-arguments" I.e., dash instead of space. The old commands are left in place, but marked deprecated. We need to adjust a couple testcases, because the relevant tests use gdb_test_no_output and the old commands are no longer silent: (gdb) set print raw frame-arguments on Warning: command 'set print raw frame-arguments' is deprecated. Use 'set print raw-frame-arguments'. gdb/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * NEWS (Changed commands): Mention set/show print raw-frame-arguments, and that "set/show print raw frame-arguments" are now deprecated. * cli/cli-decode.c (add_setshow_boolean_cmd): Now returns the command. * command.h (add_setshow_boolean_cmd): Return cmd_list_element *. * stack.c (_initialize_stack): Install "set/show print raw-frame-arguments", and deprecate "set/show print raw frame-arguments". * valprint.c (_initialize_valprint): Deprecate "set/show print raw". gdb/doc/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * gdb.texinfo (Print Settings): Document "set/show print raw-frame-arguments" instead of "set/show print raw frame-arguments". gdb/testsuite/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * gdb.guile/scm-frame-args.exp: Use "set print raw-frame-arguments" instead of "set print raw frame-arguments". * gdb.python/py-frame-args.exp: Likewise. |

Add previous_saved_command_line to allow a command to repeat a previous command.
Currently, a previous command can be repeated when the user types an empty line. This is implemented in handle_line_of_input by returning saved_command_line in case an empty line has been input. If we want a command to repeat the previous command, we need to save the previous saved_command_line, as when a command runs, the saved_command_line already contains the current command line of the command being executed. As suggested by Tom, the previous_saved_command_line is made static. At the same time, saved_command_line is also made static. The support functions/variables for the repeat command logic are now all located inside top.c. gdb/ChangeLog 2019-05-31 Philippe Waroquiers <philippe.waroquiers@skynet.be> * top.h (saved_command_line): Remove declaration. * top.c (previous_saved_command_line, previous_repeat_arguments): New variables. (saved_command_line): Make static, define together with other 'repeat variables'. (dont_repeat): Clear repeat_arguments. (repeat_previous, get_saved_command_line, save_command_line): New functions. (gdb_init): Initialize saved_command_line and previous_saved_command_line. * main.c (captured_main_1): Remove saved_command_line initialization. * event-top.c (handle_line_of_input): Update to use the new 'repeat' related functions instead of direct access to saved_command_line. * command.h (repeat_previous, get_saved_command_line, save_command_line): New declarations. (dont_repeat): Add comment. |

Update copyright year range in all GDB files.
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. |

gdb: Change how frames are selected for 'frame' and 'info frame'.
The 'frame' command, and thanks to code reuse the 'info frame' and 'select-frame' commands, currently have an overloaded mechanism for selecting a frame. These commands take one or two parameters, if it's one parameter then we first try to use the parameter as an integer to select a frame by level (or depth in the stack). If that fails then we treat the parameter as an address and try to select a stack frame by stack-address. If we still have not selected a stack frame, or we initially had two parameters, then GDB allows the user to view a stack frame that is not part of the current backtrace. Internally, a new frame is created with the given stack and pc addresses, and this is shown to the user. The result of this is that a typo by the user, entering the wrong stack frame level for example, can result in a brand new frame being viewed rather than an error. The purpose of this commit is to remove this overloading, while still offering the same functionality through some new sub-commands. By making the default behaviour of 'frame' (and friends) be to select a stack frame by level index, it is hoped that enough backwards-compatibility is maintained that users will not be overly inconvenienced. The 'frame', 'select-frame', and 'info frame' commands now all take a frame specification string as an argument, this string can be any of the following: (1) An integer. This is treated as a frame level. If a frame for that level does not exist then the user gets an error. (2) A string like 'level <LEVEL>', where <LEVEL> is a frame level as in option (1) above. (3) A string like 'address <STACK-ADDRESS>', where <STACK-ADDRESS> is a stack-frame address. If there is no frame for this address then the user gets an error. (4) A string like 'function <NAME>', where <NAME> is a function name, the inner most frame for function <NAME> is selected. If there is no frame for function <NAME> then the user gets an error. (5) A string like 'view <STACK-ADDRESS>', this views a new frame with stack address <STACK-ADDRESS>. (6) A string like 'view <STACK-ADDRESS> <PC-ADDRESS>', this views a new frame with stack address <STACK-ADDRESS> and the pc <PC-ADDRESS>. This change assumes that the most common use of the commands like 'frame' is to select a frame by frame level, it is for this reason that this is the behaviour that is kept for backwards compatibility. Any of the alternative behaviours, which are assumed to be less used, now require a change in user behaviour. The MI command '-stack-select-frame' has not been changed. This ensures that we maintain backwards compatibility for existing frontends. gdb/ChangeLog: (NEWS): Mention changes to frame related commands. * cli/cli-decode.c (add_cmd_suppress_notification): New function.

Add set_repeat_arguments function
The "x", "list", and "show commands" commands have special repetition behavior: repeating the command doesn't re-run it with the same arguments This is currently implemented by modifying the passed-in argument; but that won't work properly with const arguments (and seems pretty obscure besides).

Introduce class completion_tracker & rewrite completion<->readline interaction
This patch reworks the whole completion machinery, and prepares it for later enhancements. Adds a new "completion_tracker" class that is meant to hold everything about the state of the current completion operation. This class now has the responsibility of tracking the list of completion matches, and checking whether the max completions limit has been reached. You can look at this as this patch starting out by C++fying the existing "completion_tracker" in symtab.c (it's just an htab_t typedef currently), moving it to completer.h/c, and then making it a class/generalizing/enhancing it. Unlike with the current tracking, completion_tracker now checks whether the limit has been reached on each completion match list insertion. This both simplifies the max-completions handling code (maybe_add_completion_enum is gone, for example), and is a prerequisite for follow up patches. The current completion_tracker is only used for symbol completions, and the symbol code gets at the current instance via globals. This patch cleans that up by adding a completion_tracker reference to the signature of the completion functions, and passing the tracker around everywhere necessary. Then, the patch changes how the completion match list is handed over to readline. Currently, we're using the rl_completion_entry_function readline entry point, and the patch switches to rl_attempted_completion_function. A following patch will want to let GDB itself decide the common completion prefix between all matches (what readline calls the "lowest common denominator"), instead of having readline compute it, and that's not possible with the rl_completion_entry_function entry point. Also, rl_attempted_completion_function lets GDB hand over the match list to readline as an array in one go instead of passing down matches one by one, so from that angle it's a nicer entry point anyway. Lastly, the patch catches exceptions around the readline entry points, because we can't let C++ exceptions cross readline. We handle that in the readline input entry point, but the completion entry point isn't guarded, so GDB can abort if completion throws. E.g., in current master: (gdb) b -function "fun<tab> terminate called after throwing an instance of 'gdb_exception_RETURN_MASK_ERROR' Aborted (core dumped) This patch fixes that.

Clean up "completer_handle_brkchars" callback handling
This patch cleans up "completer_handle_brkchars" callback handling: - Renames the function typedef to better match its intent: completer_ftype_void -> completer_handle_brkchars_ftype - Factors out common code in complete_line_internal handling the "handle_brkchars" callback to a separate function. - Centralizes all the "completer method" to "handle_brkchars method" mapping in a single function. gdb/ChangeLog: 2017-07-17 Pedro Alves <palves@redhat.com> * cli/cli-decode.c (set_cmd_completer_handle_brkchars): Adjust to renames. * cli/cli-decode.h (struct cmd_list_element) <completer>: Move comments to completer_ftype's declaration. <completer_handle_brkchars>: Change type to completer_handle_brkchars_ftype. * command.h (completer_ftype): Add describing comment and give names to parameters.

gdb/command.h: Include common/scoped_restore.h
command.h depends on scoped_restore: extern scoped_restore_tmpl<int> prevent_dont_repeat (void); But doesn't include the corresponding header ("common/scoped_restore.h"). We haven't noticed a problem because utils.h includes scoped_restore.h, and defs.h includes utils.h. However, a patch that makes "symtab.h" include "completer.h", exposed the issue: https://sourceware.org/ml/gdb-patches/2017-06/msg00023.html. Without this fix that would break building all .o files like this: In file included from src/gdb/completer.h:21:0, from src/gdb/symtab.h:28, from src/gdb/language.h:26, from src/gdb/frame.h:72, from src/gdb/gdbarch.h:39, from src/gdb/defs.h:636, from src/gdb/top.c:20: src/gdb/command.h:434:8: error: ‘scoped_restore_tmpl’ does not name a type extern scoped_restore_tmpl<int> prevent_dont_repeat (void); ^ Makefile:1911: recipe for target 'top.o' failed because defs.h includes gdbarch.h before it includes utils.h. gdb/ChangeLog: 2017-06-28 Pedro Alves <palves@redhat.com> * command.h: Include "common/scoped_restore.h". |

Add alias command to cmd_list_element
When we add alias command, we call add_alias_cmd and pass the alias name and command name. This implicitly requires the command and its prefix commands are already added to cmdlist. This may not be true, for example, add_com_alias ("tty", "set inferior-tty", class_alias, 0); "inferior-tty" command is added to setlist, but setlist may not be added to cmdlist (It depends on the order of related _initialize_XXX functions called) so that we can't find "set inferior-tty" from cmdlist. This patch fixes this problem by passing cmd_list_element of "inferior-tty" to add_alias_cmd, so that cmd_list_element of "inferior-tty" doesn't have to be reachable from cmdlist at that moment. gdb: 2017-05-17 Yao Qi <yao.qi@linaro.org> * cli/cli-decode.c (add_alias_cmd): New function. * command.h (add_alias_cmd): Declare. * infcmd.c (_initialize_infcmd): Don't call add_com_alias, instead call add_alias_cmd. gdb/testsuite: 2017-05-17 Simon Marchi <simon.marchi@ericsson.com> * gdb.base/set-inferior-tty.exp (test_set_inferior_tty): Add argument command. (top-level): Invoke test_set_inferior_tty. |

Update. * guile/guile.c (gdbscm_execute_gdb_command): Update. * command.h (prevent_dont_repeat): Change return type. * breakpoint.c (bpstat_do_actions_1): Update. |

Emit inferior, thread and frame selection events to all UIs
With this patch, when an inferior, thread or frame is explicitly selected by the user, notifications will appear on all CLI and MI UIs. When a GDB console is integrated in a front-end, this allows the front-end to follow a selection made by the user ont he CLI, and it informs the user about selection changes made behind the scenes by the front-end. This patch addresses PR gdb/20487. In order to communicate frame changes to the front-end, this patch adds a new field to the =thread-selected event for the selected frame. The idea is that since inferior/thread/frame can be seen as a composition, it makes sense to send them together in the same event. The vision would be to eventually send the inferior information as well, if we find that it's needed, although the "=thread-selected" event would be ill-named for that job. Front-ends need to handle this new field if they want to follow the frame selection changes that originate from the console. The format of the frame attribute is the same as what is found in the *stopped events. Here's a detailed example for each command and the events they generate: thread ------ 1. CLI command: thread 1.3 MI event: =thread-selected,id="3",frame={...} 2. MI command: -thread-select 3 CLI event: [Switching to thread 1.3 ...] 3. MI command (CLI-in-MI): thread 1.3 MI event/reply: &"thread 1.3\n" ~"#0 child_sub_function () ... =thread-selected,id="3",frame={level="0",...} ^done frame ----- 1. CLI command: frame 1 MI event: =thread-selected,id="3",frame={level="1",...} 2. MI command: -stack-select-frame 1 CLI event: #1 0x00000000004007f0 in child_function... 3. MI command (CLI-in-MI): frame 1 MI event/reply: &"frame 1\n" ~"#1 0x00000000004007f9 in ..." =thread-selected,id="3",frame={level="1"...} ^done inferior -------- Inferior selection events only go from the console to MI, since there's no way to select the inferior in pure MI. 1. CLI command: inferior 2 MI event: =thread-selected,id="3" Note that if the user selects an inferior that is not started or exited, the MI doesn't receive a notification. Since there is no threads to select, the =thread-selected event does not apply... 2. MI command (CLI-in-MI): inferior 2 MI event/reply: &"inferior 2\n" ~"[Switching to inferior 2 ...]" =thread-selected,id="4",frame={level="0"...} ^done Internal implementation detail: this patch makes it possible to suppress notifications caused by a CLI command, like what is done in mi-interp.c. This means that it's now possible to use the add_com_suppress_notification function to register a command with some event suppressed. It is used to implement the select-frame command in this patch. The function command_notifies_uscc_observer was added to extract the rather complicated logical expression from the if statement. It is also now clearer what that logic does: if the command used by the user already notifies the user_selected_context_changed observer, there is not need to notify it again. It therefore protects again emitting the event twice. No regressions, tested on ubuntu 14.04 x86 with target boards unix and native-extended-gdbserver. gdb/ChangeLog: YYYY-MM-DD Antoine Tremblay <antoine.tremblay@ericsson.com> YYYY-MM-DD Simon Marchi <simon.marchi@ericsson.com> PR gdb/20487 * NEWS: Mention new frame field of =thread-selected event. * cli/cli-decode.c (add_cmd): Initialize c->suppress_notification.

C++ keyword cleanliness, mostly auto-generated
This patch renames symbols that happen to have names which are reserved keywords in C++. Most of this was generated with Tromey's cxx-conversion.el script. Some places where later hand massaged a bit, to fix formatting, etc. And this was rebased several times meanwhile, along with re-running the script, so re-running the script from scratch probably does not result in the exact same output. I don't think that matters anyway. gdb/ 2015-02-27 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> Rename symbols whose names are reserved C++ keywords throughout. gdb/gdbserver/ 2015-02-27 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> Rename symbols whose names are reserved C++ keywords throughout. |

PR python/16699: GDB Python command completion with overriden complete vs. completer class
This PR came from a Red Hat bug that was filed recently. I checked and it still exists on HEAD, so here's a proposed fix. Although this is marked as a Python backend bug, this is really about the completion mechanism used by GDB. Since this code reminds me of my first attempt to make a good noodle, it took me quite some time to fix it in a non-intrusive way. The problem is triggered when one registers a completion method inside a class in a Python script, rather than registering the command using a completer class directly. For example, consider the following script: class MyFirstCommand(gdb.Command): def __init__(self): gdb.Command.__init__(self,'myfirstcommand',gdb.COMMAND_USER,gdb.COMPLETE_FILENAME) def invoke(self,argument,from_tty): raise gdb.GdbError('not implemented') class MySecondCommand(gdb.Command): def __init__(self): gdb.Command.__init__(self,'mysecondcommand',gdb.COMMAND_USER) def invoke(self,argument,from_tty): raise gdb.GdbError('not implemented') def complete(self,text,word): return gdb.COMPLETE_FILENAME MyFirstCommand () MySecondCommand () When one loads this into GDB and tries to complete filenames for both myfirstcommand and mysecondcommand, she gets: (gdb) myfirstcommand /hom<TAB> (gdb) myfirstcommand /home/ ^ ... (gdb) mysecondcommand /hom<TAB> (gdb) mysecondcommand /home ^ (The "^" marks the final position of the cursor after the TAB). So we see that myfirstcommand honors the COMPLETE_FILENAME class (as specified in the command creation), but mysecondcommand does not. After some investigation, I found that the problem lies with the set of word break characters that is used for each case. The set should be the same for both commands, but it is not. During the process of deciding which type of completion should be used, the code in gdb/completer.c:complete_line_internal analyses the command that requested the completion and tries to determine the type of completion wanted by checking which completion function will be called (e.g., filename_completer for filenames, location_completer for locations, etc.). This all works fine for myfirstcommand, because immediately after the command registration the Python backend already sets its completion function to filename_completer (which then causes the complete_line_internal function to choose the right set of word break chars). However, for mysecondcommand, this decision is postponed to when the completer function is evaluated, and the Python backend uses an internal completer (called cmdpy_completer). complete_line_internal doesn't know about this internal completer, and can't choose the right set of word break chars in time, which then leads to a bad decision when completing the "/hom" word. So, after a few attempts, I decided to create another callback in "struct cmd_list_element" that will be responsible for handling the case when there is an unknown completer function for complete_line_internal to work with. So far, only the Python backend uses this callback, and only when the user provides a completer method instead of registering the command directly with a completer class. I think this is the best option because it not very intrusive (all the other commands will still work normally), but especially because the whole completion code is so messy that it would be hard to fix this without having to redesign things. I have regtested this on Fedora 18 x86_64, without regressions. I also included a testcase. gdb/ChangeLog: 2014-09-03 Sergio Durigan Junior <sergiodj@redhat.com> PR python/16699 * cli/cli-decode.c (set_cmd_completer_handle_brkchars): New function.
