Convert observers to C++
This converts observers from using a special source-generating script
to be plain C++. This version of the patch takes advantage of C++11
by using std::function and variadic templates; incorporates Pedro's
patches; and renames the header file to "observable.h" (this change
eliminates the need for a clean rebuild).
Note that Pedro's patches used a template lambda in tui-hooks.c, but
this failed to compile on some buildbot instances (presumably due to
differing C++ versions); I replaced this with an ordinary template
function.
Regression tested on the buildbot.

Associate dummy_frame with ptid
This patch is to add ptid into dummy_frame and extend frame_id to
dummy_frame_id (which has a ptid field). With this change, GDB uses
dummy_frame_id (thread ptid and frame_id) to find the dummy frames.
Currently, dummy frames are looked up by frame_id, which isn't
accurate in non-stop or multi-process mode. The test case
gdb.multi/dummy-frame-restore.exp shows the problem and this patch can
fix it.
Test dummy-frame-restore.exp makes two inferiors stop at
different functions, say, inferior 1 stops at f1 while inferior 2
stops at f2. Set a breakpoint to a function, do the inferior call
in two inferiors, and GDB has two dummy frames of the same frame_id.
When the inferior call is finished, GDB will look up a dummy frame
from its stack/list and restore the inferior's regcache. Two
inferiors are finished in different orders, the inferiors' states are
restored differently, which is wrong. Running dummy-frame-restore.exp
under un-patched GDB, we'll get two fails:
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 2
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 1
With this patch applied, GDB will choose the correct dummy_frame to
restore for a given inferior, because ptid is considered when looking up
dummy frames. Two fails above are fixed.
Regression tested on x86_64-linux, both native and gdbserver.

Associate dummy_frame with ptid
This patch is to add ptid into dummy_frame and extend frame_id to
dummy_frame_id (which has a ptid field). With this change, GDB uses
dummy_frame_id (thread ptid and frame_id) to find the dummy frames.
Currently, dummy frames are looked up by frame_id, which isn't
accurate in non-stop or multi-process mode. The test case
gdb.multi/dummy-frame-restore.exp shows the problem and this patch can
fix it.
Test dummy-frame-restore.exp makes two inferiors stop at
different functions, say, inferior 1 stops at f1 while inferior 2
stops at f2. Set a breakpoint to a function, do the inferior call
in two inferiors, and GDB has two dummy frames of the same frame_id.
When the inferior call is finished, GDB will look up a dummy frame
from its stack/list and restore the inferior's regcache. Two
inferiors are finished in different orders, the inferiors' states are
restored differently, which is wrong. Running dummy-frame-restore.exp
under un-patched GDB, we'll get two fails:
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 2
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 1
With this patch applied, GDB will choose the correct dummy_frame to
restore for a given inferior, because ptid is considered when looking up
dummy frames. Two fails above are fixed.
Regression tested on x86_64-linux, both native and gdbserver.

Add some more casts (1/2)
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...

Per-inferior/Inferior-qualified thread IDs
This commit changes GDB to track thread numbers per-inferior. Then,
if you're debugging multiple inferiors, GDB displays
"inferior-num.thread-num" instead of just "thread-num" whenever it
needs to display a thread:
(gdb) info inferiors
Num Description Executable
1 process 6022 /home/pedro/gdb/tests/threads
* 2 process 6037 /home/pedro/gdb/tests/threads
(gdb) info threads
Id Target Id Frame
1.1 Thread 0x7ffff7fc2740 (LWP 6022) "threads" (running)
1.2 Thread 0x7ffff77c0700 (LWP 6028) "threads" (running)
1.3 Thread 0x7ffff7fc2740 (LWP 6032) "threads" (running)
2.1 Thread 0x7ffff7fc1700 (LWP 6037) "threads" (running)
2.2 Thread 0x7ffff77c0700 (LWP 6038) "threads" (running)
* 2.3 Thread 0x7ffff7fc2740 (LWP 6039) "threads" (running)
(gdb)
...
(gdb) thread 1.1
[Switching to thread 1.1 (Thread 0x7ffff7fc2740 (LWP 8155))]
(gdb)
...
etc.
You can still use "thread NUM", in which case GDB infers you're
referring to thread NUM of the current inferior.
The $_thread convenience var and Python's InferiorThread.num attribute
are remapped to the new per-inferior thread number. It's a backward
compatibility break, but since it only matters when debugging multiple
inferiors, I think it's worth doing.
Because MI thread IDs need to be a single integer, we keep giving
threads a global identifier, _in addition_ to the per-inferior number,
and make MI always refer to the global thread IDs. IOW, nothing
changes from a MI frontend's perspective.
Similarly, since Python's Breakpoint.thread and Guile's
breakpoint-thread/set-breakpoint-thread breakpoint methods need to
work with integers, those are adjusted to work with global thread IDs
too. Follow up patches will provide convenient means to access
threads' global IDs.
To avoid potencially confusing users (which also avoids updating much
of the testsuite), if there's only one inferior and its ID is "1",
IOW, the user hasn't done anything multi-process/inferior related,
then the "INF." part of thread IDs is not shown. E.g,.:
(gdb) info inferiors
Num Description Executable
* 1 process 15275 /home/pedro/gdb/tests/threads
(gdb) info threads
Id Target Id Frame
* 1 Thread 0x7ffff7fc1740 (LWP 15275) "threads" main () at threads.c:40
(gdb) add-inferior
Added inferior 2
(gdb) info threads
Id Target Id Frame
* 1.1 Thread 0x7ffff7fc1740 (LWP 15275) "threads" main () at threads.c:40
(gdb)
No regressions on x86_64 Fedora 20.

Associate dummy_frame with ptid
This patch is to add ptid into dummy_frame and extend frame_id to
dummy_frame_id (which has a ptid field). With this change, GDB uses
dummy_frame_id (thread ptid and frame_id) to find the dummy frames.
Currently, dummy frames are looked up by frame_id, which isn't
accurate in non-stop or multi-process mode. The test case
gdb.multi/dummy-frame-restore.exp shows the problem and this patch can
fix it.
Test dummy-frame-restore.exp makes two inferiors stop at
different functions, say, inferior 1 stops at f1 while inferior 2
stops at f2. Set a breakpoint to a function, do the inferior call
in two inferiors, and GDB has two dummy frames of the same frame_id.
When the inferior call is finished, GDB will look up a dummy frame
from its stack/list and restore the inferior's regcache. Two
inferiors are finished in different orders, the inferiors' states are
restored differently, which is wrong. Running dummy-frame-restore.exp
under un-patched GDB, we'll get two fails:
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 2
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 1
With this patch applied, GDB will choose the correct dummy_frame to
restore for a given inferior, because ptid is considered when looking up
dummy frames. Two fails above are fixed.
Regression tested on x86_64-linux, both native and gdbserver.

Associate dummy_frame with ptid
This patch is to add ptid into dummy_frame and extend frame_id to
dummy_frame_id (which has a ptid field). With this change, GDB uses
dummy_frame_id (thread ptid and frame_id) to find the dummy frames.
Currently, dummy frames are looked up by frame_id, which isn't
accurate in non-stop or multi-process mode. The test case
gdb.multi/dummy-frame-restore.exp shows the problem and this patch can
fix it.
Test dummy-frame-restore.exp makes two inferiors stop at
different functions, say, inferior 1 stops at f1 while inferior 2
stops at f2. Set a breakpoint to a function, do the inferior call
in two inferiors, and GDB has two dummy frames of the same frame_id.
When the inferior call is finished, GDB will look up a dummy frame
from its stack/list and restore the inferior's regcache. Two
inferiors are finished in different orders, the inferiors' states are
restored differently, which is wrong. Running dummy-frame-restore.exp
under un-patched GDB, we'll get two fails:
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 2
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 1
With this patch applied, GDB will choose the correct dummy_frame to
restore for a given inferior, because ptid is considered when looking up
dummy frames. Two fails above are fixed.
Regression tested on x86_64-linux, both native and gdbserver.

dummy_frame_id (which has a ptid field). With this change, GDB uses
dummy_frame_id (thread ptid and frame_id) to find the dummy frames.
Currently, dummy frames are looked up by frame_id, which isn't
accurate in non-stop or multi-process mode. The test case
gdb.multi/dummy-frame-restore.exp shows the problem and this patch can
fix it.
Test dummy-frame-restore.exp makes two inferiors stop at
different functions, say, inferior 1 stops at f1 while inferior 2
stops at f2. Set a breakpoint to a function, do the inferior call
in two inferiors, and GDB has two dummy frames of the same frame_id.
When the inferior call is finished, GDB will look up a dummy frame
from its stack/list and restore the inferior's regcache. Two
inferiors are finished in different orders, the inferiors' states are
restored differently, which is wrong. Running dummy-frame-restore.exp
under un-patched GDB, we'll get two fails:
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 2
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 1
With this patch applied, GDB will choose the correct dummy_frame to
restore for a given inferior, because ptid is considered when looking up
dummy frames. Two fails above are fixed.
Regression tested on x86_64-linux, both native and gdbserver.

Associate dummy_frame with ptid
This patch is to add ptid into dummy_frame and extend frame_id to
dummy_frame_id (which has a ptid field). With this change, GDB uses
dummy_frame_id (thread ptid and frame_id) to find the dummy frames.
Currently, dummy frames are looked up by frame_id, which isn't
accurate in non-stop or multi-process mode. The test case
gdb.multi/dummy-frame-restore.exp shows the problem and this patch can
fix it.
Test dummy-frame-restore.exp makes two inferiors stop at
different functions, say, inferior 1 stops at f1 while inferior 2
stops at f2. Set a breakpoint to a function, do the inferior call
in two inferiors, and GDB has two dummy frames of the same frame_id.
When the inferior call is finished, GDB will look up a dummy frame
from its stack/list and restore the inferior's regcache. Two
inferiors are finished in different orders, the inferiors' states are
restored differently, which is wrong. Running dummy-frame-restore.exp
under un-patched GDB, we'll get two fails:
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 2
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 1
With this patch applied, GDB will choose the correct dummy_frame to
restore for a given inferior, because ptid is considered when looking up
dummy frames. Two fails above are fixed.
Regression tested on x86_64-linux, both native and gdbserver.

Replace some xmalloc-family functions with XNEW-family ones
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.

Associate dummy_frame with ptid
This patch is to add ptid into dummy_frame and extend frame_id to
dummy_frame_id (which has a ptid field). With this change, GDB uses
dummy_frame_id (thread ptid and frame_id) to find the dummy frames.
Currently, dummy frames are looked up by frame_id, which isn't
accurate in non-stop or multi-process mode. The test case
gdb.multi/dummy-frame-restore.exp shows the problem and this patch can
fix it.
Test dummy-frame-restore.exp makes two inferiors stop at
different functions, say, inferior 1 stops at f1 while inferior 2
stops at f2. Set a breakpoint to a function, do the inferior call
in two inferiors, and GDB has two dummy frames of the same frame_id.
When the inferior call is finished, GDB will look up a dummy frame
from its stack/list and restore the inferior's regcache. Two
inferiors are finished in different orders, the inferiors' states are
restored differently, which is wrong. Running dummy-frame-restore.exp
under un-patched GDB, we'll get two fails:
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 2
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 1
With this patch applied, GDB will choose the correct dummy_frame to
restore for a given inferior, because ptid is considered when looking up
dummy frames. Two fails above are fixed.
Regression tested on x86_64-linux, both native and gdbserver.

Add some more casts (1/2)
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...

Add some more casts (1/2)
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...

Associate dummy_frame with ptid
This patch is to add ptid into dummy_frame and extend frame_id to
dummy_frame_id (which has a ptid field). With this change, GDB uses
dummy_frame_id (thread ptid and frame_id) to find the dummy frames.
Currently, dummy frames are looked up by frame_id, which isn't
accurate in non-stop or multi-process mode. The test case
gdb.multi/dummy-frame-restore.exp shows the problem and this patch can
fix it.
Test dummy-frame-restore.exp makes two inferiors stop at
different functions, say, inferior 1 stops at f1 while inferior 2
stops at f2. Set a breakpoint to a function, do the inferior call
in two inferiors, and GDB has two dummy frames of the same frame_id.
When the inferior call is finished, GDB will look up a dummy frame
from its stack/list and restore the inferior's regcache. Two
inferiors are finished in different orders, the inferiors' states are
restored differently, which is wrong. Running dummy-frame-restore.exp
under un-patched GDB, we'll get two fails:
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 2
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 1
With this patch applied, GDB will choose the correct dummy_frame to
restore for a given inferior, because ptid is considered when looking up
dummy frames. Two fails above are fixed.
Regression tested on x86_64-linux, both native and gdbserver.

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.

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.

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.

Convert observers to C++
This converts observers from using a special source-generating script
to be plain C++. This version of the patch takes advantage of C++11
by using std::function and variadic templates; incorporates Pedro's
patches; and renames the header file to "observable.h" (this change
eliminates the need for a clean rebuild).
Note that Pedro's patches used a template lambda in tui-hooks.c, but
this failed to compile on some buildbot instances (presumably due to
differing C++ versions); I replaced this with an ordinary template
function.
Regression tested on the buildbot.
