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.

Canceling pagination caused by execution command from command line aborts readline/gdb
This fixes:
$ ./gdb program -ex "set height 2" -ex "start"
...
Reading symbols from /home/pedro/gdb/tests/threads...done.
---Type <return> to continue, or q <return> to quit---^CQuit << ctrl-c triggers a Quit
*type something*
readline: readline_callback_read_char() called with no handler!
Aborted
$
Usually, if an error propagates all the way to the top level, we'll
re-enable stdin, in case the command that was running was a
synchronous command. That's done in the event loop's actual loop
(event-loop.c:start_event_loop). However, if a foreground execution
command is run before the event loop starts and throws, nothing is
presently reenabling stdin, which leaves sync_execution set.
When we do start the event loop, because sync_execution is still
(mistakenly) set, display_gdb_prompt removes the readline input
callback, even though stdin is registered in the event loop. Any
input from here on results in readline aborting.
Such commands are run through catch_command_errors,
catch_command_errors_const, so add the tweak there.

gdb/17347 - Regression: GDB stopped on run with attached process
Doing:
gdb --pid=PID -ex run
Results in GDB getting a SIGTTIN, and thus ending stopped. That's
usually indicative of a missing target_terminal_ours call.
E.g., from the PR:
$ sleep 1h & p=$!; sleep 0.1; gdb -batch sleep $p -ex run
[1] 28263
[1] Killed sleep 1h
[2]+ Stopped gdb -batch sleep $p -ex run
The workaround is doing:
gdb -ex "attach $PID" -ex "run"
instead of
gdb [-p] $PID -ex "run"
With the former, gdb waits for the attach command to complete before
moving on to the "run" command, because the interpreter is in sync
mode at this point, within execute_command. But for the latter,
attach_command is called directly from captured_main, and thus misses
that waiting. IOW, "run" is running before the attach continuation
has run, before the program stops and attach completes. The broken
terminal settings are just one symptom of that. Any command that
queries or requires input results in the same.
The fix is to wait in catch_command_errors (which is specific to
main.c nowadays), just like we wait in execute_command.

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.

Remove init_cli_cmds
I noticed that init_cli_cmds only installs a command, and so doesn't
need to be handled specially. This patch merges it into
_initialize_cli_cmds.
The help text is constructed dynamically, which is sometimes an
indication that special treatment is needed; but in this case it is
just to insert the value of "gdbinit", which is created at
compile-time and not modified; so this doesn't affect the result.
This version also removes the "gdbinit" global. There's no need for
it, as GDBINIT can be used instead. Note, though, that the help text
in question must still be dynamically constructed, in order to be
i18n-friendly.

Eliminate catch_errors
If you want to use catch_errors with a function with parameters, then
currently you have to manually write a "capture" struct wrapping the
arguments and marshall/unmarshall that.
https://sourceware.org/ml/gdb-patches/2017-09/msg00834.html proposed
adjusting catch_errors to use gdb::function_view, which would allow
passing lambdas with automatic captures. However, it seems like using
TRY/CATCH directly instead ends up producing clearer and easier to
debug code. This is what this commit does.
Note that removing catch_errors exposes further cleanup opportunities
around no longer having to follow catch_errors callback type, and also
removes a few cleanups.
I didn't do anything to save/restore current_uiout because I think
that should be the responsibility of the code that changes
current_uiout in the first place.
(Another approach could be to make catch_errors a variadic template
like:
template<typename Function, typename... Args>
int catch_errors (const char *errstring, return_mask mask,
Function &&func, Args... args);
and then with:
extern void function_with_args (int, int);
extern void function_with_no_args ();
calls to the above functions would be wrapped like this:
catch_errors ("some error happened", RETURN_MASK_ERROR,
function_with_args, arg1, arg2);
catch_errors ("some error happened", RETURN_MASK_ERROR,
function_with_no_args);
but I'm thinking that that doesn't improve much if at all either.)

Make each UI have its own interpreter list, top level interpreter,
current interpreter, etc. The "interpreter_async" global is not

Replace the sync_execution global with a new enum prompt_state tristate
When sync_execution (a boolean) is true, it means we're running a
foreground command -- we hide the prompt stop listening to input, give
the inferior the terminal, then go to the event loop waiting for the
target to stop.
With multiple independent UIs, we need to track whether each UI is
synchronously blocked waiting for the target. IOW, if you do
"continue" in one console, that console stops accepting commands, but
you should still be free to type other commands in the others
consoles.
Just simply making sync_execution be per-UI alone not sufficient,
because of this in fetch_inferior_event:
/* If the inferior was in sync execution mode, and now isn't,
restore the prompt (a synchronous execution command has finished,
and we're ready for input). */
if (current_ui->async && was_sync && !sync_execution)
observer_notify_sync_execution_done ();
We'd have to record at entry the "was_sync" state for each UI, not
just of the current UI.
This patch instead replaces the sync_execution flag by a per-UI
tristate flag indicating the command line prompt state:
enum prompt_state
{
/* The command line is blocked simulating synchronous execution.
This is used to implement the foreground execution commands
('run', 'continue', etc.). We won't display the prompt and
accept further commands until the execution is actually over. */
PROMPT_BLOCKED,
/* The command finished; display the prompt before returning back to
the top level. */
PROMPT_NEEDED,
/* We've displayed the prompt already, ready for input. */
PROMPTED,
;
I think the end result is _much_ clearer than the current code, and,
it addresses the original motivation too.

Eliminate catch_errors
If you want to use catch_errors with a function with parameters, then
currently you have to manually write a "capture" struct wrapping the
arguments and marshall/unmarshall that.
https://sourceware.org/ml/gdb-patches/2017-09/msg00834.html proposed
adjusting catch_errors to use gdb::function_view, which would allow
passing lambdas with automatic captures. However, it seems like using
TRY/CATCH directly instead ends up producing clearer and easier to
debug code. This is what this commit does.
Note that removing catch_errors exposes further cleanup opportunities
around no longer having to follow catch_errors callback type, and also
removes a few cleanups.
I didn't do anything to save/restore current_uiout because I think
that should be the responsibility of the code that changes
current_uiout in the first place.
(Another approach could be to make catch_errors a variadic template
like:
template<typename Function, typename... Args>
int catch_errors (const char *errstring, return_mask mask,
Function &&func, Args... args);
and then with:
extern void function_with_args (int, int);
extern void function_with_no_args ();
calls to the above functions would be wrapped like this:
catch_errors ("some error happened", RETURN_MASK_ERROR,
function_with_args, arg1, arg2);
catch_errors ("some error happened", RETURN_MASK_ERROR,
function_with_no_args);
but I'm thinking that that doesn't improve much if at all either.)

Make stdin be per UI
This commit makes each UI have its own "stdin" stream pointer. This
is used to determine whether the "from_tty" argument to
execute_command, etc. should be true.
Related, this commit makes input_from_terminal_p take an UI parameter,
and then avoids the gdb_has_a_terminal in it. gdb_has_a_terminal only
returns info on gdb's own main/primary terminal (the real stdin).
However, the places that call input_from_terminal_p really want to
know is whether the command came from an interactive tty. This patch
thus renames input_from_terminal_p to input_interactive_p for clarity,
and then makes input_interactive_p check for "set interactive" itself,
along with ISATTY, instead of calling gdb_has_a_terminal. Actually,
quit_force wants to call input_interactive_p _after_ stdin is closed,
we can't call ISATTY that late. So instead we save the result of
ISATTY in a field of the UI.

Usually, if an error propagates all the way to the top level, we'll

(event-loop.c:start_event_loop). However, if a foreground execution
command is run before the event loop starts and throws, nothing is
presently reenabling stdin, which leaves sync_execution set.
When we do start the event loop, because sync_execution is still
(mistakenly) set, display_gdb_prompt removes the readline input
callback, even though stdin is registered in the event loop. Any
input from here on results in readline aborting.
Such commands are run through catch_command_errors,

Replace the sync_execution global with a new enum prompt_state tristate
When sync_execution (a boolean) is true, it means we're running a
foreground command -- we hide the prompt stop listening to input, give
the inferior the terminal, then go to the event loop waiting for the
target to stop.
With multiple independent UIs, we need to track whether each UI is

you should still be free to type other commands in the others

Just simply making sync_execution be per-UI alone not sufficient,
because of this in fetch_inferior_event:
/* If the inferior was in sync execution mode, and now isn't,

if (current_ui->async && was_sync && !sync_execution)
observer_notify_sync_execution_done ();
We'd have to record at entry the "was_sync" state for each UI, not
just of the current UI.
This patch instead replaces the sync_execution flag by a per-UI
tristate flag indicating the command line prompt state:
enum prompt_state
{
/* The command line is blocked simulating synchronous execution.

PROMPT_BLOCKED,
/* The command finished; display the prompt before returning back to
the top level. */
PROMPT_NEEDED,
/* We've displayed the prompt already, ready for input. */
PROMPTED,

I think the end result is _much_ clearer than the current code, and,
it addresses the original motivation too.

gdb/17347 - Regression: GDB stopped on run with attached process
Doing:
gdb --pid=PID -ex run
Results in GDB getting a SIGTTIN, and thus ending stopped. That's
usually indicative of a missing target_terminal_ours call.
E.g., from the PR:
$ sleep 1h & p=$!; sleep 0.1; gdb -batch sleep $p -ex run
[1] 28263
[1] Killed sleep 1h
[2]+ Stopped gdb -batch sleep $p -ex run
The workaround is doing:
gdb -ex "attach $PID" -ex "run"
instead of
gdb [-p] $PID -ex "run"
With the former, gdb waits for the attach command to complete before
moving on to the "run" command, because the interpreter is in sync
mode at this point, within execute_command. But for the latter,
attach_command is called directly from captured_main, and thus misses
that waiting. IOW, "run" is running before the attach continuation
has run, before the program stops and attach completes. The broken
terminal settings are just one symptom of that. Any command that
queries or requires input results in the same.
The fix is to wait in catch_command_errors (which is specific to
main.c nowadays), just like we wait in execute_command.

catch (const gdb_exception &e)

Split TRY_CATCH into TRY + CATCH
This patch splits the TRY_CATCH macro into three, so that we go from
this:
~~~
volatile gdb_exception ex;
TRY_CATCH (ex, RETURN_MASK_ERROR)
{
}
if (ex.reason < 0)
{
}
~~~
to this:
~~~
TRY
{
}
CATCH (ex, RETURN_MASK_ERROR)
{
}
END_CATCH
~~~
Thus, we'll be getting rid of the local volatile exception object, and
declaring the caught exception in the catch block.
This allows reimplementing TRY/CATCH in terms of C++ exceptions when
building in C++ mode, while still allowing to build GDB in C mode
(using setjmp/longjmp), as a transition step.
TBC, after this patch, is it _not_ valid to have code between the TRY
and the CATCH blocks, like:
TRY
{
}
// some code here.
CATCH (ex, RETURN_MASK_ERROR)
{
}
END_CATCH
Just like it isn't valid to do that with C++'s native try/catch.
By switching to creating the exception object inside the CATCH block
scope, we can get rid of all the explicitly allocated volatile
exception objects all over the tree, and map the CATCH block more
directly to C++'s catch blocks.
The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was
done with a script, rerun from scratch at every rebase, no manual
editing involved. After the mechanical conversion, a few places
needed manual intervention, to fix preexisting cases where we were
using the exception object outside of the TRY_CATCH block, and cases
where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH
after this patch]. The result was folded into this patch so that GDB
still builds at each incremental step.
END_CATCH is necessary for two reasons:
First, because we name the exception object in the CATCH block, which
requires creating a scope, which in turn must be closed somewhere.
Declaring the exception variable in the initializer field of a for
block, like:
#define CATCH(EXCEPTION, mask) \
for (struct gdb_exception EXCEPTION; \
exceptions_state_mc_catch (&EXCEPTION, MASK); \
EXCEPTION = exception_none)
would avoid needing END_CATCH, but alas, in C mode, we build with C90,
which doesn't allow mixed declarations and code.
Second, because when TRY/CATCH are wired to real C++ try/catch, as
long as we need to handle cleanup chains, even if there's no CATCH
block that wants to catch the exception, we need for stop at every
frame in the unwind chain and run cleanups, then rethrow. That will
be done in END_CATCH.
After we require C++, we'll still need TRY/CATCH/END_CATCH until
cleanups are completely phased out -- TRY/CATCH in C++ mode will
save/restore the current cleanup chain, like in C mode, and END_CATCH
catches otherwise uncaugh exceptions, runs cleanups and rethrows, so
that C++ cleanups and exceptions can coexist.
IMO, this still makes the TRY/CATCH code look a bit more like a
newcomer would expect, so IMO worth it even if we weren't considering
C++.

Add support for the readnever concept
The purpose of this concept is to turn the load of debugging
information off, either globally (via the '--readnever' option), or
objfile-specific. The implementation proposed here is an extension of
the patch distributed with Fedora GDB; looking at the Fedora patch
itself and the history, one can see some reasons why it was never
resubmitted:
- The patch appears to have been introduced as a workaround, at
least initially;
- The patch is far from perfect, as it simply shunts the load of
DWARF debugging information, without really worrying about the
other debug format.
- Who really does non-symbolic debugging anyways?
One use of this feature is when a user simply wants to do the
following sequence: attach, dump core, detach. Loading the debugging
information in this case is an unnecessary cause of delay.
This patch expands the version shipped with Fedora GDB in order to
make the feature available for all the debuginfo backends, not only
for DWARF. It also implements a per-objfile flag which can be
activated by using the "-readnever" command when using the
'add-symbol-file' or 'symbol-file' commands.
It's also worth mentioning that this patch tests whether GDB correctly
fails to initialize if both '--readnow' and '--readnever' options are
passed.
Tested on the BuildBot.

Fix struct, union, and enum nesting in C++
In C, an enum or structure defined inside other structure has global
scope just like it had been defined outside the struct in the first
place. However, in C++, such a nested structure is given a name that
is nested inside the structure. This patch moves such affected
structures/enums out to global scope, so that code using them works
the same in C++ as it works today in C.

gdb: Fix build breakage with GCC 4.1 and --disable-nls
Ref: https://sourceware.org/ml/gdb-patches/2016-09/msg00203.html
The std::{min,max} patch caused build failures when configuring GDB
with with --disable-nls and using GCC 4.1.
The reason is this bit in common/gdb_locale.h:
#ifdef ENABLE_NLS
...
#else
# define gettext(Msgid) (Msgid)
...
#endif
This causes problems if the <libintl.h> header is first included at
any point after "gdb_locale.h".
Specifically, the gettext&co declarations in libintl.h:
extern char *gettext (__const char *__msgid)
__THROW __attribute_format_arg__ (1);
end up broken after preprocessing:
extern char *(__const char *__msgid)
throw () __attribute__ ((__format_arg__ (1)));
After the std::min/std::max change to include <algorithm>, this now
happens with at least the GCC 4.1 copy of <algorithm>, which includes
<libintl.h> via <bits/stl_algobase.h>, <iosfwd>, and
<bits/c++locale.h>.
The fix is to simply remove the troublesome *gettext and *textdomain
macros, leaving only the _ and N_ ones.
gdb/ChangeLog:
2016-09-19 Pedro Alves <palves@redhat.com>
* common/gdb_locale.h [!ENABLE_NLS] (gettext, dgettext, dcgettext,
textdomain, bindtextdomain): Delete macros.
* main.c (captured_main) [!ENABLE_NLS]: Skip bintextdomain and
textdomain calls.

Add support for the readnever concept
The purpose of this concept is to turn the load of debugging
information off, either globally (via the '--readnever' option), or
objfile-specific. The implementation proposed here is an extension of
the patch distributed with Fedora GDB; looking at the Fedora patch
itself and the history, one can see some reasons why it was never
resubmitted:
- The patch appears to have been introduced as a workaround, at
least initially;
- The patch is far from perfect, as it simply shunts the load of
DWARF debugging information, without really worrying about the
other debug format.
- Who really does non-symbolic debugging anyways?
One use of this feature is when a user simply wants to do the
following sequence: attach, dump core, detach. Loading the debugging
information in this case is an unnecessary cause of delay.
This patch expands the version shipped with Fedora GDB in order to
make the feature available for all the debuginfo backends, not only
for DWARF. It also implements a per-objfile flag which can be
activated by using the "-readnever" command when using the
'add-symbol-file' or 'symbol-file' commands.
It's also worth mentioning that this patch tests whether GDB correctly
fails to initialize if both '--readnow' and '--readnever' options are
passed.
Tested on the BuildBot.

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

Add support for the readnever concept
The purpose of this concept is to turn the load of debugging
information off, either globally (via the '--readnever' option), or
objfile-specific. The implementation proposed here is an extension of
the patch distributed with Fedora GDB; looking at the Fedora patch
itself and the history, one can see some reasons why it was never
resubmitted:
- The patch appears to have been introduced as a workaround, at
least initially;
- The patch is far from perfect, as it simply shunts the load of
DWARF debugging information, without really worrying about the
other debug format.
- Who really does non-symbolic debugging anyways?
One use of this feature is when a user simply wants to do the
following sequence: attach, dump core, detach. Loading the debugging
information in this case is an unnecessary cause of delay.
This patch expands the version shipped with Fedora GDB in order to
make the feature available for all the debuginfo backends, not only
for DWARF. It also implements a per-objfile flag which can be
activated by using the "-readnever" command when using the
'add-symbol-file' or 'symbol-file' commands.
It's also worth mentioning that this patch tests whether GDB correctly
fails to initialize if both '--readnow' and '--readnever' options are
passed.
Tested on the BuildBot.

Fix regression: cannot start with LD_PRELOAD=libSegFault.so (PR gdb/18653#c7)
At https://sourceware.org/bugzilla/show_bug.cgi?id=18653#c7, Andrew
reports that the fix for PR gdb/18653 made GDB useless if you preload
libSegFault.so, because GDB internal-errors on startup:
$ LD_PRELOAD=libSegFault.so gdb
src/gdb/common/signals-state-save-restore.c:64: internal-error: unexpected signal handler
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Aborted (core dumped)
$
The internal error comes from the code saving the signal dispositions
inherited from gdb's parent:

This commit downgrades the internal error to a warning. You'll get
instead:
~~~
$ LD_PRELOAD=libSegFault.so gdb
warning: Found custom handler for signal 11 (Segmentation fault) preinstalled.
Some signal dispositions inherited from the environment (SIG_DFL/SIG_IGN)
won't be propagated to spawned programs.

This also moves the location where save_original_signals_state is
called a bit further below (to after option processing), so that "-q"
disables the warning:
~~~

New testcase included.
gdb/ChangeLog:
2018-01-05 Pedro Alves <palves@redhat.com>
PR gdb/18653
* common/signals-state-save-restore.c

find a custom handler preinstalled, instead of internal erroring.
But only warn if !quiet.

* main.c (captured_main_1): Move save_original_signals_state call
after option handling, and pass QUIET.

Add new command to create extra console/mi UIs
With all the previous plumbing in place, it's now easy to add a
command that actually creates a new console/mi UI.
The intended use case is to make it possible and easy for MI frontends
to provide a fully featured GDB console to users, with readline
support, command line editing, history, etc., just like if gdb was
started on the command line. Currently MI frontends have to try to
implement all of that theirselves and make use of "-interpreter-exec
console ...", which is far from perfect. If you ever tried Eclipse's
gdb console window, you'll know what I mean...
Instead of trying to multiplex console through MI, this command let's
just leverage all the built in readline/editing support already inside
gdb.
The plan is for the MI frontend to start GDB in regular console mode,
running inside a terminal emulator widget embedded in Eclipse (which
already exists, for supporting the shell widget; other frontends have
similar widgets), and then tell GDB to run a full MI interpreter on an
specified input/output device, independent of the console.
My original prototype planned to do things the other way around --
start GDB in MI mode, and then start an extra CLI console on separate
tty. I handed over that prototype to Marc Khouzam @ Eclipse CDT, and
after experimentation and discussion, we ended up concluding that
starting GDB in CLI mode instead was both easier and actually also
supported an interesting use case -- connect an Eclipse frontend to a
GDB that is already running outside Eclipse.
The current usage is "new-ui <interpreter> <tty>".
E.g., on a terminal run this scriplet:
$ cat gdb-client
#!/bin/bash
reset
tty
tail -f /dev/null
$ gdb-client
/dev/pts/15
Now run gdb on another terminal, and tell it to start a MI interpreter
on the tty of the other terminal:
...
(gdb) new-ui mi /dev/pts/15
New UI allocated
Now back to the the gdb-client terminal, we'll get an MI prompt, ready
for MI input:
/dev/pts/15
=thread-group-added,id="i1"
(gdb)
You can also start a new UI running a CLI, with:
(gdb) new-ui console /dev/pts/15
Though note that this console won't support readline command editing.
It works as if "set editing off" was entered.

Remove some text from --version output
I happened to notice recently that "gdb --version" says:
GNU gdb (GDB) 8.0.50.20170911-git
Copyright (C) 2017 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>
This is free software: you are free to change and redistribute it.
There is NO WARRANTY, to the extent permitted by law. Type "show copying"
and "show warranty" for details.
This GDB was configured as "x86_64-pc-linux-gnu".
Type "show configuration" for configuration details.
For bug reporting instructions, please see:
<http://www.gnu.org/software/gdb/bugs/>.
Find the GDB manual and other documentation resources online at:
<http://www.gnu.org/software/gdb/documentation/>.
For help, type "help".
Type "apropos word" to search for commands related to "word".
This is a bit on the wordy side, but also references interactive
commands, which I think doesn't really make sense for --version.
This patch removes some text from --version, while leaving it in the
"show version" output. It also adds a newline between the URLs and
the "For help, ..." text, because I thought that was easier to read.
Finally, it indents one of the URLs, since that was simpler to read,
but not the other URL, because the current format is specified by the
GNU coding standards section on "--version".
Now the --version output looks like:
GNU gdb (GDB) 8.1.50.20180511-git

Eliminate catch_errors
If you want to use catch_errors with a function with parameters, then
currently you have to manually write a "capture" struct wrapping the
arguments and marshall/unmarshall that.
https://sourceware.org/ml/gdb-patches/2017-09/msg00834.html proposed
adjusting catch_errors to use gdb::function_view, which would allow
passing lambdas with automatic captures. However, it seems like using
TRY/CATCH directly instead ends up producing clearer and easier to
debug code. This is what this commit does.
Note that removing catch_errors exposes further cleanup opportunities
around no longer having to follow catch_errors callback type, and also
removes a few cleanups.
I didn't do anything to save/restore current_uiout because I think
that should be the responsibility of the code that changes
current_uiout in the first place.
(Another approach could be to make catch_errors a variadic template
like:
template<typename Function, typename... Args>
int catch_errors (const char *errstring, return_mask mask,
Function &&func, Args... args);
and then with:
extern void function_with_args (int, int);
extern void function_with_no_args ();
calls to the above functions would be wrapped like this:
catch_errors ("some error happened", RETURN_MASK_ERROR,
function_with_args, arg1, arg2);
catch_errors ("some error happened", RETURN_MASK_ERROR,
function_with_no_args);
but I'm thinking that that doesn't improve much if at all either.)

Add support for the readnever concept
The purpose of this concept is to turn the load of debugging
information off, either globally (via the '--readnever' option), or
objfile-specific. The implementation proposed here is an extension of
the patch distributed with Fedora GDB; looking at the Fedora patch
itself and the history, one can see some reasons why it was never
resubmitted:
- The patch appears to have been introduced as a workaround, at
least initially;
- The patch is far from perfect, as it simply shunts the load of
DWARF debugging information, without really worrying about the
other debug format.
- Who really does non-symbolic debugging anyways?
One use of this feature is when a user simply wants to do the
following sequence: attach, dump core, detach. Loading the debugging
information in this case is an unnecessary cause of delay.
This patch expands the version shipped with Fedora GDB in order to
make the feature available for all the debuginfo backends, not only
for DWARF. It also implements a per-objfile flag which can be
activated by using the "-readnever" command when using the
'add-symbol-file' or 'symbol-file' commands.
It's also worth mentioning that this patch tests whether GDB correctly
fails to initialize if both '--readnow' and '--readnever' options are
passed.
Tested on the BuildBot.
