With the following C++ code:
int bar() { return 0;}
int bar(int) { return 0; }
GDB behaves as:
(gdb) list bar
file: "overload.cc", line number: 1
file: "overload.cc", line number: 2
It would be better for GDB to list the actual code around those two
locations, not just print the location. Like:
(gdb) list bar
file: "overload.cc", line number: 1
1 int bar() { return 0;}
2 int bar(int) { return 0; }
file: "overload.cc", line number: 2
1 int bar() { return 0;}
2 int bar(int) { return 0; }
That's what this this commit implements.
Tested on x86-64 GNU/Linux.

This introduces gdb_argv, a class wrapping an "argv" pointer; that is,
a pointer to a NULL-terminated array of char*, where both the array

instead.

Now, GDB is able to dynamically create i386-linux target descriptions
from features, instead of using pre-generated target descriptions. These
pre-generated target descriptions are no longer used by GDB (note that
they are still used by GDBserver).
This patch add a new maint command "maint check xml-descriptions" to test
dynamically generated tdesc are identical to these generated from xml files.

One of the most annoying (to me) things about GDB's completion is when
you have overloads in your program, and you want to set a breakpoint
in one of them:
void function(int); // set breakpoint here.
void function(long);
(gdb) b -f func[TAB]
(gdb) b -f function( # ok, gdb completed as much as possible.
(gdb) b -f function([TAB] # show me the overloads, please.
<_all_ symbols in the program are shown...>
E.g., when debugging GDB, that'd be:
(gdb) b -f function([TAB]
(anonymous namespace)::get_global()::global pt_insn_get_offset@plt scm_new_port_table_entry
asprintf pt_pkt_alloc_decoder scm_new_port_table_entry@plt
asprintf@plt pt_pkt_alloc_decoder@plt scm_out_of_range
bt_ctf_get_char_array pt_pkt_sync_forward scm_out_of_range@plt
bt_ctf_get_char_array@plt pt_pkt_sync_forward@plt scm_putc
bt_ctf_get_uint64 pwrite scm_putc@plt
bt_ctf_get_uint64@plt pwrite@plt scm_reverse_x
bt_ctf_iter_read_event PyErr_Restore scm_reverse_x@plt
bt_ctf_iter_read_event@plt PyErr_Restore@plt scm_set_port_filename_x
<snip...>
Now that's a load of completely useless completions.
The reason GDB offers those is that the completer relies on readline
figuring out the completion word point in the input line based on the
language's word break characters, which include "(". So readline
tells the completer to complete on "", the string that is after '('.
Likewise, if you type "function(i[TAB]" to try to complete to "int",
you're out of luck. GDB shows you all the symbols in the program that
start with "i"... This makes sense for the expression completer, as
what you'd want to type is e.g., a global variable, say:
(gdb) print function(i[TAB]
but, it makes no sense when specifying a function name for a
breakpoint location.
To get around that limitation, users need to quote the function name,
like:
(gdb) b -f 'function([TAB]
function(int) function(long)
(gdb) b 'function(i[TAB]
(gdb) b 'function(int)' # now completes correctly!
Note that the quoting is only necessary for completion. Creating the
breakpoint does not require the quoting:
(gdb) b -f function(int) [RET]
Breakpoint 1 at ....
This patch removes this limitation.
(
Actually, it's a necessary patch, though not sufficient. That'll
start working correctly by the end of the series. With this patch, if try it,
you'll see:
(gdb) b -f function(i[TAB]
(gdb) b -f function
i.e., gdb strips everything after the "(". That's caused by some code
in symtab.c that'll be eliminated further down the series. These
patches are all unfortunately interrelated, which is also the reason
new tests only appear much later in the series.
But let's ignore that reality for the remainder of the description.
)
So... this patch gets rid of the need for quoting.
It does that by adding a way for a completer to control the exact
completion word point that readline should start the completion
request for, instead of letting readline try to figure it out using
the current language's word break chars array, and often failing.
In the case above, we want the completer to figure out that it's
completing a function name that starts with "function(i". It now
does.
It took me a while to figure out a way to ask readline to "use this
exact word point", and for a while I feared that it'd be impossible
with current readline (and having to rely on master readline for core
functionality is something I'd like to avoid very much). Eventually,
after several different attempts, I came up with what is described in
the comment above gdb_custom_word_point_brkchars in the patch.
With this patch, the handle_brkchars phase of the explicit location
completer advances the expected word point as it parses the input line
left to right, until it figures out exactly what we're completing,
instead of expecting readline to break the string using the word break
characters, and then having the completer heuristically fix up a bad
decision by parsing the input string backwards. This allows correctly
knowning that we're completing a symbol name after -function, complete
functions without quoting, etc.
Later, we'll make use of this same mechanims to implement a proper
linespec completer that avoids need for quoting too.

The linespec/locations/completer testcase added later in the series
tests every completion with both TAB completion and the "complete"
command. This exposed problems in the "complete" command, around
determining the completion word point.
First, the complete command has a too-simple approximation of what
readline's TAB-completion code does to find the completion word point.
Unfortunately, readline doesn't expose the functionality it uses
internally, so to fix this this patch copies over the relevant code,
and adjusts it a bit to better fit the use cases we need it for.
(Specifically, our version avoids relying on the
rl_word_break_characters, etc. globals, and instead takes those as
arguments.)
A following patch will want to use this function for TAB-completion
too, but the "complete" command was a good excuse to split this to a
separate patch.
Then, notice how the complete_command does not call into the completer
for the command being completed to determine the right set of word
break characters. It always uses the default set. That is fixed by
having the "complete" command call into complete_line_internal for a
full handle_brkchars phase, just TAB-completion.

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. This will be exercised in the new tests added
later on in the series.

This removes make_cleanup_delete_event_location and instead changes
the various location functions to return an event_location_up, a new
unique_ptr typedef.
This is largely straightforward, but be sure to examine the
init_breakpoint_sal change. I believe the code I deleted there is
dead, because "location != NULL" can never be true in that branch; but
you should double-check.

gdb/ChangeLog:
Update copyright year range in all GDB files.

This patch finalizes the C++ conversion of the ui-out subsystem, by
turning the ui_out and ui_out_impl structures into a single class
hierarchy. ui_out functions are turned into virtual methods of that new
class, so as a result there are a lot of call sites to update.
In the previous version of the patchset, there were separate ui_out and
ui_out_impl classes, but it wasn't really useful and added boilerplate.
In this version there is simply an ui_out base class that is
extended for CLI, TUI and MI.
It's a bit hard to maintain a ChangeLog for such a big patch, I did my
best but I'm sure there are some missing or outdated info in there...

This patch changes some code in cli-cmds.c to use std::string rather
than dyn-string, removing some cleanups. Since this was the last use
of dyn-string in gdb, this patch also removes
make_cleanup_dyn_string_delete.

* utils.h (make_cleanup_dyn_string_delete): Remove declaration.
* utils.c: Don't include dyn-string.h.

* cli/cli-cmds.c: Include <string>. Don't include dyn-string.h.
(argv_to_string): Rename. Change return type to std::string.

This fixes PR gdb/20604. The bug here is that passing an invalid
expression to "quit" -- e.g., "quit()" -- causes gdb to enter a
non-functioning state.
The immediate problem is that quit_force resets the terminal before
evaluating the expression. However, it seemed to me that it doesn't
really make sense to pass the quit_force argument to kill_or_detach
(which passes it to to_detach), first because conflating the exit
status for "quit" and the signal to pass when detaching doesn't make
sense, and second because to_detach implementations generally only
accept a constant here, while "quit" accepts an expression. So, I
removed that.
As an aside, I think the "detach SIGNO" functionality is not
documented.
Built and regtested on x86-64 Fedora 24.

commit makes us re-set only locations of the current program space.
If we loaded symbols to a program space (e.g., "file" command or some
shared library was loaded), GDB must run through all breakpoints and
determine if any new locations need to be added to the breakpoint.
However, there's no reason to recreate locations for _other_ program
spaces, as those haven't changed.
Similarly, when we create a new inferior, through e.g., a fork, GDB
must run through all breakpoints and determine if any new locations
need to be added to the breakpoint. There's no reason to destroy the
locations of the parent inferior and other inferiors. We know those
won't change.
In addition to being inneficient, resetting breakpoints of inferiors
that are currently running is problematic, because:
- some targets can't read memory while the inferior is running.
- the inferior might exit while we're re-setting its breakpoints,
which may confuse prologue skipping.
I went through all the places where we call breakpoint_re_set, and it
seems to me that all can be changed to only re-set locations of the
current program space.
The patch that reversed threads order in "info threads" etc. happened
to make gdb.threads/fork-plus-thread.exp expose this problem when
testing on x86/-m32. The problem was latent and masked out by chance
by the code-cache:
https://sourceware.org/ml/gdb-patches/2016-01/msg00213.html
Tested on x86-64 F20, native (-m64/-m32) and extended-remote
gdbserver.
Fixes the regression discussed in the url above with --target_board=unix/-m32:
-FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: inferior 1 exited
+PASS: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: inferior 1 exited
-FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: no threads left (timeout)
-FAIL: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: only inferior 1 left (the program exited)
+PASS: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: no threads left
+PASS: gdb.threads/fork-plus-threads.exp: detach-on-fork=off: only inferior 1 left

gdb/ChangeLog:
Update year range in copyright notice of all files.

Reference the 'listsize' setting in the help text for the 'list' command
to help users find this setting.
gdb/ChangeLog:
* cli/cli-cmds.c (_initialize_cli_cmds): Extend help text for
'list' command.

When a a user uses 'list +' to list forward through a source file they
eventually reach the end of the source file. Subsequent uses of 'list
+' result in an error message like this, that let the user know they are
at the end of the source file:
Line number XXX out of range; FILENAME has YYY lines.
Compare this to the current behaviour of 'list -' which lists backwards
through a source file. When the user reaches the beginning of the
source file, subsequent uses of 'list -' result in the command silently
returning. This can be confusing if the previous uses of 'list -' have
scrolled off the users display, the user receives no reminder that the
have already seen the start of the file.
After this commit a use of 'list -' when the user has already seen the
start of a file will receive the following error:
Already at the start of FILENAME.
gdb/ChangeLog:
* cli/cli-cmds.c (list_command): Add an error when trying to use
'-' to scan read off the start of the source file.
gdb/testsuite/ChangeLog:
* gdb.base/list.exp (test_list_forward): Add end of file error
test.
(test_repeat_list_command): Add end of file error test.
(test_list_backwards): Add beginning of file error test.

There is an inconsistency with the handling of the special +/- arguments
to the list command.
For the very first time that list is used (after the inferior has
changed locations) then only the first character of the argument string
is checked, so 'list +BLAH' will operate as 'list +' and 'list -----FOO'
will operate as 'list -'. This compares to each subsequent use of list,
where the whole argument string is checked, so 'list +BLAH' will try to
list lines of code around the function '+BLAH'.
This commit unifies the behaviour so that the whole argument string is
checked, in order to list the next 10, or previous 10 lines from a file
only 'list +' and 'list -' are now valid.
gdb/ChangeLog:
* cli/cli-cmds.c (list_command): Check that the argument string is
a single character, either '+' or '-'.
gdb/testsuite/ChangeLog:
* gdb.base/list.exp (test_list_invalid_args): New function,
defined, and called.

Note: I needed to split this patch in two, otherwise it's too big for
the mailing list.
This patch adds explicit casts to situations where a void pointer is
assigned to a pointer to the "real" type. Building in C++ mode requires
those assignments to use an explicit cast. This includes, for example:
- callback arguments (cleanups, comparison functions, ...)
- data attached to some object (objfile, program space, etc) in the form
of a void pointer
- "user data" passed to some function
This patch comes from the commit "(mostly) auto-generated patch to insert
casts needed for C++", taken from Pedro's C++ branch.
Only files built on x86 with --enable-targets=all are modified, so the
native files for other arches will need to be dealt with separately.
I built-tested this with --enable-targets=all and reg-tested. To my
surprise, a test case (selftest.exp) had to be adjusted.
Here's the ChangeLog entry. Again, this was relatively quick to make
despite the length, thanks to David Malcom's script, although I don't
believe it's very useful information in that particular case...

Most allocation functions (if not all) return a void* pointing to the
allocated memory. In C++, we need to add an explicit cast when
assigning the result to a pointer to another type (which is the case
more often than not).
The content of this patch is taken from Pedro's branch, from commit
"(mostly) auto-generated patch to insert casts needed for C++". I
validated that the changes make sense and manually reflowed the code to
make it respect the coding style. I also found multiple places where I
could use XNEW/XNEWVEC/XRESIZEVEC/etc.
Thanks a lot to whoever did that automated script to insert casts, doing
it completely by hand would have taken a ridiculous amount of time.
Only files built on x86 with --enable-targets=all are modified. This
means that all other -nat.c files are untouched and will have to be
dealt with later by using appropiate compilers. Or maybe we can try to
build them with a regular g++ just to know where to add casts, I don't
know.
I built-tested this with --enable-targets=all and reg-tested.
Here's the changelog entry, which was not too bad to make despite the
size, thanks to David Malcom's script. I fixed some bits by hand, but
there might be some wrong parts left (hopefully not).

This patch is part of the make-gdb-buildable-in-C++ effort. The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family. This avoids adding an explicit cast, so
it keeps the code a bit more readable. Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.
I only changed calls that were obviously allocating memory for one or
multiple "objects". Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).
- xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
- xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
- xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
- xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
- xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
- obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
- obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
- alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
- alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)
Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.
I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files. For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

The "source centric" /m option to the disassemble command is often
unhelpful, e.g., in the presence of optimized code.
This patch adds a /s modifier that is better.
For one, /m only prints instructions from the originating source file,
leaving out instructions from e.g., inlined functions from other files.

This patch converts the code base to use the new struct event_location
API being introduced. This patch preserves the current functionality and
adds no new features.
The "big picture" API usage introduced by this patch may be illustrated
with a simple exmaple. Where previously developers would write:
void
my_command (char *arg, int from_tty)
{
create_breakpoint (..., arg, ...);
...
}
one now uses:
void
my_command (char *arg, int from_tty)
{
struct event_locaiton *location;
struct cleanup *back_to;
location = string_to_event_locaiton (&arg, ...);
back_to = make_cleanup_delete_event_location (location);
create_breakpoint (..., location, ...);
do_cleanups (back_to);
}
Linespec-decoding functions (now called location-decoding) such as
decode_line_full no longer skip argument pointers over processed input.
That functionality has been moved into string_to_event_location as
demonstrated above.

Pedro Alves:
The commands that enables aren't even documented in the manual.
Judging from that, I assume that only wdb users would ever really
be using the --xdb switch.
I think it's time to drop "support" for the --xdb switch too. I
looked through the commands that that exposes, the only that looked
potentially interesting was "go", but then it's just an alias
for "tbreak+jump", which can easily be done with "define go...end".
I'd rather free up the "go" name for something potentially
more interesting (either run control, or maybe even unrelated,
e.g., for golang).

This commit adds a new exception, MAX_COMPLETIONS_REACHED_ERROR, to be
thrown whenever the completer has generated too many candidates to
be useful. A new user-settable variable, "max_completions", is added
to control this behaviour. A top-level completion limit is added to
complete_line_internal, as the final check to ensure the user never
sees too many completions. An additional limit is added to
default_make_symbol_completion_list_break_on, to halt time-consuming
symbol table expansions.

have empty bodies.
User-defined commands that have empty bodies weren't being shown because
the print function returned too soon. Now, it prints the command's name
before checking if it has any body at all. This also fixes the same
problem on "show user <myemptycommand>", which wasn't being printed due
to a similar reason.
gdb/Changelog:
* cli/cli-cmds.c (show_user): Use cli_user_command_p to
decide whether we display the command on "show user".
* cli/cli-script.c (show_user_1): Only verify cmdlines after
printing command name.
* cli/cli-decode.h (cli_user_command_p): Declare new function.
* cli/cli-decode.c (cli_user_command_p): Create helper function
to verify whether cmd_list_element is a user-defined command.
gdb/testsuite/Changelog:
* gdb.base/commands.exp: Add tests to verify user-defined
commands with empty bodies.
* gdb.python/py-cmd.exp: Test that we don't show user-defined
python commands in `show user command`.
* gdb.python/scm-cmd.exp: Test that we don't show user-defined
scheme commands in `show user command`.

Currently there are many calls to help_list that pass the constant -1
as the "class" value. However, the parameter is declared as being of
type enum command_class, and uses of the constant violate this
abstraction.
This patch fixes the error everywhere it occurs in the gdb sources.
Tested by rebuilding.

I noticed that "list" behaves differently in CLI vs MI. Particularly:
$ ./gdb -nx -q ./testsuite/gdb.mi/mi-cli
Reading symbols from /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.mi/mi-cli...done.
(gdb) start
Temporary breakpoint 1 at 0x40054d: file ../../../src/gdb/testsuite/gdb.mi/basics.c, line 62.

63 callee1 (2, "A string argument.", 3.5);
64
65 do_nothing (); /* Hello, World! */
66
(gdb)
Note the list started at line 57. IOW, the program stopped at line
62, and GDB centered the list on that.
compare with:

Here the list starts at line 62, where the program was stopped.
This happens because print_stack_frame, called from both normal_stop
and mi_on_normal_stop, is the function responsible for setting the
current sal from the selected frame, overrides the PRINT_WHAT
argument, and only after that does it decide whether to center the
current sal line or not, based on the overridden value, and it will
always decide false.
(The print_stack_frame call in mi_on_normal_stop is a little different
from the call in normal_stop, in that it is an unconditional
SRC_AND_LOC call. A future patch will make those uniform.)
A previous version of this patch made MI uniform with CLI here, by
making print_stack_frame also center when MI is active. That changed
the output of a "list" command in mi-cli.exp, to expect line 57
instead of 62, as per the example above.
However, looking deeper, that list in question is the first "list"
after the program stops, and right after the stop, before the "list",
the test did "set listsize 1". Let's try the same thing with the CLI:
(gdb) start
62 callee1 (2, "A string argument.", 3.5);
(gdb) set listsize 1
(gdb) list
57 {
Huh, that's unexpected. Why the 57? It's because print_stack_frame,
called in reaction to the breakpoint stop, expecting the next "list"
to show 10 lines (the listsize at the time) around line 62, sets the
lines listed range to 57-67 (62 +/- 5). If the user changes the
listsize before "list", why would we still show that range? Looks
bogus to me.
So the fix for this whole issue should be delay trying to center the
listing to until actually listing, so that the correct listsize can be
taken into account. This makes MI and CLI uniform too, as it deletes
the center code from print_stack_frame.
A series of tests are added to list.exp to cover this. mi-cli.exp was
after all correct all along, but it now gains an additional test that
lists lines with listsize 10, to ensure the centering is consistent
with CLI's.
One related Python test changed related output -- it's a test that
prints the line number after stopping for a breakpoint, similar to the
new list.exp tests. Previously we'd print the stop line minus 5 (due
to the premature centering), now we print the stop line. I think
that's a good change.
Tested on x86_64 Fedora 20.

I have a case that could use an exception for "unsupported feature".
I found UNSUPPORTED_ERROR, but looking deeper, I think as is, reusing
it for other things would be fragile. E.g., if the Python script
sourced by source_script_from_stream triggers any other missing
functionality that would result in UNSUPPORTED_ERROR being propagated
out to source_script_from_stream, that would confuse the error for
Python not being built into GDB.
This patch thus redoes things a little. Instead of using an exception
for the "No Python" scenario, check whether Python is configured in
before actually trying to source the file. It adds a new function
instead of using #ifdef HAVE_PYTHON directly, as that is better at
avoiding bitrot, as both Python and !Python paths are visible to the
compiler this way.
Tested on Fedora 17, with and without Python.
