Extend the 'cli_suppress_notification' struct with a new field,
'normal_stop', that can be used for checking if printing normal stop
events on the CLI should be suppressed.
This patch only introduces the flag. The subsequent patch adds a user
command to turn the flag off/on.

|
Convert the suppress_notification flag for the CLI from int to bool.

The getter and setter in struct setting always receive and return values
by const reference. This is not necessary for scalar values (like bool
and int), but more importantly it makes it a bit annoying to write a
getter, you have to use a scratch static variable or something similar
that you can refer to:
const bool &
my_getter ()
{
static bool value;
value = function_returning_bool ();
return value;
}
Change the getter and setter function signatures to receive and return
value by value instead of by reference, when the underlying data type is
scalar. This means that string-based settings will still use
references, but all others will be by value. The getter above would
then be re-written as:
bool
my_getter ()
{
return function_returning_bool ();
}
This is useful for a patch later in this series that defines a boolean
setting with a getter and a setter.

There's a common pattern to call add_basic_prefix_cmd and
add_show_prefix_cmd to add matching set and show commands. Add the
add_setshow_prefix_cmd function to factor that out and use it at a few
places.

The commit 702991711a91bd47b209289562843a11e7009396 (gdb: Have setter
and getter callbacks for settings) makes it possible for a setting not
to be backed by a memory buffer but use callback functions instead to
retrieve or set the setting's value.
An assertion was not properly updated to take into account that the
m_var member (which points to a memory buffer, if used) might be nullptr
if the setting uses callback functions. If the setting is backed by a
memory buffer, the m_var has to be non nullptr, which is already checked
before the pointer is dereferenced.
This commit removes this assertion as it is not valid anymore.

GDB can notify observers when a parameter is changed.
To do that, do_set_command (in gdb/cli/cli-setshow.c) compares the new
value against the old one before updating it, and based on that notifies
observers. This looks like something like:
int valuechanged = 0;
switch (cmd->var.type ())
{
case var_integer:
{
LONGEST new_val = parse_and_eval_long (arg)
if (new_val != cmd->var.get<int> ())
{
cmd->var.get<int> (new_val);
value_changes = 1;
}
}
case var_uinteger:
case var_zuinteger:
{
unsigned int val
= parse_cli_var_uinteger (c->var->type (), &arg, true);
if (c->var->get<unsigned int> () != val)
{
c->var->set<unsigned int> (val);
option_changed = true;
}
}
case...
/* And so on for all possible var_types. */
}
This comparison is done for each possible var_type, which leads to
unnecessary logic duplication.
In this patch I propose to move all those checks in one place within the
setting setter method. This limits the code duplication and simplifies
the do_set_command implementation.
This patch also changes slightly the way a value change is detected.
Instead of comparing the user provided value against the current value
of the setting, we compare the value of the setting before and after the
set operation. This is meant to handle edge cases where trying to set
an unrecognized value would be equivalent to a noop (the actual value
remains unchanged). Doing this requires that the original value needs
to be copied before the update, which can be non trivial for
std::string.
There should be no user visible change introduced by this commit.
Tested on x86_64 GNU/Linux.

The main motivation behind this improvement is to help the
implementation of a patch Simon Marchi is preparing to fix a bug when
MI or Python try to access parameters that are inferior dependent (see
PR/28085).
This commit extends the previous ones, which introduces the setting
object to represent a static variable whose value can be set or shown
with the appropriate commands. This patch proposes that a setting can
either contain a pointer to a static variable holding a setting, or
pointers to a pair of setter and getter callback functions.
The callbacks functions can be used to retrieve or change the value with
custom logic. This is useful when the source of truth for a given
setting is not contained in the variable pointed to by the setting
instance.
Given that the callback function call is hidden within the setting
abstraction introduced earlier, none of the sites accessing the setting
needs to be updated. The registered getter or setter is used whatever
the way to access it is (through MI, Python, Guile, the "with" command
and the $_gdb_setting / $_gdb_setting_str convenience functions).
All the add_setshow_*_cmd are given a new overload that will accept the
pair of function pointers (set / get functions) instead of the pointer
to a global variable.
Tested on GNU/Linux x86_64 with no regression observed.

String-like settings (var_string, var_filename, var_optional_filename,
var_string_noescape) currently take a pointer to a `char *` storage
variable (typically global) that holds the setting's value. I'd like to
"mordernize" this by changing them to use an std::string for storage.
An obvious reason is that string operations on std::string are often
easier to write than with C strings. And they avoid having to do any
manual memory management.
Another interesting reason is that, with `char *`, nullptr and an empty
string often both have the same meaning of "no value". String settings
are initially nullptr (unless initialized otherwise). But when doing
"set foo" (where `foo` is a string setting), the setting now points to
an empty string. For example, solib_search_path is nullptr at startup,
but points to an empty string after doing "set solib-search-path". This
leads to some code that needs to check for both to check for "no value".
Or some code that converts back and forth between NULL and "" when
getting or setting the value. I find this very error-prone, because it
is very easy to forget one or the other. With std::string, we at least
know that the variable is not "NULL". There is only one way of
representing an empty string setting, that is with an empty string.
I was wondering whether the distinction between NULL and "" would be
important for some setting, but it doesn't seem so. If that ever
happens, it would be more C++-y and self-descriptive to use
optional<string> anyway.
Actually, there's one spot where this distinction mattered, it's in
init_history, for the test gdb.base/gdbinit-history.exp. init_history
sets the history filename to the default ".gdb_history" if it sees that
the setting was never set - if history_filename is nullptr. If
history_filename is an empty string, it means the setting was explicitly
cleared, so it leaves it as-is. With the change to std::string, this
distinction doesn't exist anymore. This can be fixed by moving the code
that chooses a good default value for history_filename to
_initialize_top. This is ran before -ex commands are processed, so an
-ex command can then clear that value if needed (what
gdb.base/gdbinit-history.exp tests).
Another small improvement, in my opinion is that we can now easily
give string parameters initial values, by simply initializing the global
variables, instead of xstrdup-ing it in the _initialize function.
In Python and Guile, when registering a string-like parameter, we
allocate (with new) an std::string that is owned by the param_smob (in
Guile) and the parmpy_object (in Python) objects.
This patch started by changing all relevant add_setshow_* commands to
take an `std::string *` instead of a `char **` and fixing everything
that failed to build. That includes of course all string setting
variable and their uses.
string_option_def now uses an std::string also, because there's a
connection between options and settings (see
add_setshow_cmds_for_options).
The add_path function in source.c is really complex and twisted, I'd
rather not try to change it to work on an std::string right now.
Instead, I added an overload that copies the std:string to a `char *`
and back. This means more copying, but this is not used in a hot path
at all, so I think it is acceptable.

cmd_list_element can contain a pointer to data that can be set and / or
shown. This is achieved with the void* VAR member which points to the
data that can be accessed, while the VAR_TYPE member (of type enum
var_types) indicates how to interpret the data pointed to.
With this pattern, the user of the cmd_list_element needs to know what
is the storage type associated with a given VAR_TYPES in order to do
the proper casting. No automatic safeguard is available to prevent
miss-use of the pointer. Client code typically looks something like:
switch (c->var_type)
{
case var_zuinteger:
unsigned int v = *(unsigned int*) c->var;
...
break;
case var_boolean:
bool v = *(bool *) c->var;
...
break;
...
}
This patch proposes to add an abstraction around the var_types and void*
pointer pair. The abstraction is meant to prevent the user from having
to handle the cast and verify that the data is read or written as a type
that is coherent with the setting's var_type. This is achieved by
introducing the struct setting which exposes a set of templated get /
set member functions. The template parameter is the type of the
variable that holds the referred variable.
Using those accessors allows runtime checks to be inserted in order to
ensure that the data pointed to has the expected type. For example,
instantiating the member functions with bool will yield something
similar to:
const bool &get<bool> () const
{
gdb_assert (m_var_type == var_boolean);
gdb_assert (m_var != nullptr);
return *static_cast<bool *> (m_var);
}
void set<bool> (const bool &var)
{
gdb_assert (m_var_type == var_boolean);
gdb_assert (m_var != nullptr);
*static_cast<bool *> (m_var) = var;
}
Using the new abstraction, our initial example becomes:
switch (c->var_type)
{
case var_zuinteger:
unsigned int v = c->var->get<unsigned int> ();
...
break;
case var_boolean:
bool v = c->var->get<bool> ();
...
break;
...
}
While the call site is still similar, the introduction of runtime checks
help ensure correct usage of the data.
In order to avoid turning the bulk of add_setshow_cmd_full into a
templated function, and following a suggestion from Pedro Alves, a
setting can be constructed from a pre validated type erased reference to
a variable. This is what setting::erased_args is used for.
Introducing an opaque abstraction to describe a setting will also make
it possible to use callbacks to retrieve or set the value of the setting
on the fly instead of pointing to a static chunk of memory. This will
be done added in a later commit.
Given that a cmd_list_element may or may not reference a setting, the
VAR and VAR_TYPES members of the struct are replaced with a
gdb::optional<setting> named VAR.
Few internal function signatures have been modified to take into account
this new abstraction:
-The functions value_from_setting, str_value_from_setting and
get_setshow_command_value_string used to have a 'cmd_list_element *'
parameter but only used it for the VAR and VAR_TYPE member. They now
take a 'const setting &' parameter instead.
- Similarly, the 'void *' and a 'enum var_types' parameters of
pascm_param_value and gdbpy_parameter_value have been replaced with a
'const setting &' parameter.
No user visible change is expected after this patch.
Tested on GNU/Linux x86_64, with no regression noticed.

I don't understand what the sfunc function type in
cmd_list_element::function is for. Compared to cmd_simple_func_ftype,
it has an extra cmd_list_element parameter, giving the callback access
to the cmd_list_element for the command being invoked. This allows
registering the same callback with many commands, and alter the behavior
using the cmd_list_element's context.
From the comment in cmd_list_element, it sounds like at some point it
was the callback function type for set and show functions, hence the
"s". But nowadays, it's used for many more commands that need to access
the cmd_list_element object (see add_catch_command for example).
I don't really see the point of having sfunc at all, since do_sfunc is
just a trivial shim that changes the order of the arguments. All
commands using sfunc could just as well set cmd_list_element::func to
their callback directly.
Therefore, remove the sfunc field in cmd_list_element and everything
that goes with it. Rename cmd_const_sfunc_ftype to cmd_func_ftype and
use it for cmd_list_element::func, as well as for the add_setshow
commands.

After browsing the CLI code for quite a while and trying really hard, I
reached the conclusion that I can't give a meaningful explanation of
what "sfunc" and "cfunc" functions are, in cmd_list_element. I don't
see a logic at all. That makes it very difficult to do any kind of
change. Unless somebody can make sense out of all that, I'd like to try
to retro-fit some logic in the cmd_list_element callback function code
so that we can understand what is going on, do some cleanups and add new
features.
The first change is about "cfunc". I can't figure out what the "c" in
cfunc means. It's not const, because there's already "const" in
"cmd_const_cfunc_ftype", and the previous "cmd_cfunc_ftype" had nothing
const.. It's not "cmd" or "command", because there's already "cmd" in
"cmd_const_cfunc_ftype".
The "main" command callback, cmd_list_element::func, has three
parameters, whereas cfunc has two. It is missing the cmd_list_element
parameter. So the only reason I see for cfunc to exist is to be a shim
between the three and two parameter versions. Most commands don't need
to receive the cmd_list_element object, so adding it everywhere would be
long and would just add more unnecessary boilerplate. So since this is
the "simple" version of the callback, compared to the "full", I suggest
renaming cmd_const_cfunc_ftype into cmd_simple_func_ftype, as well as
everything (like the utility functions) that goes with it.

I propose removing the context parameter from add_setshow_enum_cmd. It

The alias creation functions currently accept a name to specify the
target command. They pass this to add_alias_cmd, which needs to lookup
the target command by name.
Given that:
- We don't support creating an alias for a command before that command
exists.
- We always use add_info_alias just after creating that target command,
and therefore have access to the target command's cmd_list_element.
... change add_com_alias to accept the target command as a
cmd_list_element (other functions are done in subsequent patches). This
ensures we don't create the alias before the target command, because you
need to get the cmd_list_element from somewhere when you call the alias
creation function. And it avoids an unecessary command lookup. So it
seems better to me in every aspect.

because it's not obvious when reading code what "c->func == NULL" means.

cmd_list_element::is_command_class_help (except it doesn't give a clue
about the semantic of a NULL func value).

Previously, the prefixname field of struct cmd_list_element was manually
set for prefix commands. This seems verbose and error prone as it
required every single call to functions adding prefix commands to
specify the prefix name while the same information can be easily
generated.
Historically, this was not possible as the prefix field was null for
many commands, but this was fixed in commit
3f4d92ebdf7f848b5ccc9e8d8e8514c64fde1183 by Philippe Waroquiers, so
we can rely on the prefix field being set when generating the prefix
name.
This commit also fixes a use after free in this scenario:
* A command gets created via Python (using the gdb.Command class).
The prefix name member is dynamically allocated.
* An alias to the new command is created. The alias's prefixname is set
to point to the prefixname for the original command with a direct
assignment.
* A new command with the same name as the Python command is created.
* The object for the original Python command gets freed and its
prefixname gets freed as well.
* The alias is updated to point to the new command, but its prefixname
is not updated so it keeps pointing to the freed one.
gdb/ChangeLog:
* command.h (add_prefix_cmd): Remove the prefixname argument as
it can now be generated automatically. Update all callers.
(add_basic_prefix_cmd): Ditto.

prefix name at runtime. Update all code reading the prefix
name to use the method, and remove all code setting it.

prefixname member as it's now a method.

adds a new lookup_cmd_exact function which simplify this use case.

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.

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.

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.

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.

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.

Before this change, "help" was not showing the TUI class.
With this change:
(gdb) help
...
support -- Support facilities.
text-user-interface -- TUI is the GDB text based interface.
tracepoints -- Tracing of program execution without stopping the program.
...
(gdb) help text-user-interface
TUI is the GDB text based interface.
In TUI mode, GDB can display several text windows showing
the source file, the processor registers, the program disassembly, ...
List of commands:
+ -- Scroll window forward.
...
Note that we cannot use "tui" for the fake class command name, as "tui"
is a command.

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.

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.

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.

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.

( 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.

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".

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.

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.

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.

This removes cmd_cfunc_ftype and the non-const overload of add_cmd;
then fixes up the fallout.
For the most part this patch is straightforward. There are a few
files (go32-nat.c, windows-nat.c, and gnu-nat.c) that I could not
compile; so I made a best effort there.

This patch constifies add_info and updates all the info commands. The
bulk of this patch was written using a script; and then I did a manual
pass to fix up the remaining compilation errors.
I could not compile every changed file; in particular nto-procfs.c,
gnu-nat.c, and darwin-nat-info.c; but I at least tried to check the
correctness by inspection.
