The control variable win_resized must be cleared before responding to
it.
Otherwise there is a small window where another SIGWINCH might occur in
between the handling of an earlier SIGWINCH and the clearing of
win_resized, at which point win_resized would be set (again) by the
signal handler. Shortly thereafter we would clear win_resized even
though we only handled the earlier SIGWINCH but not the latest one.
This chain of events is all avoided if we clear win_resized first.
gdb/ChangeLog:
* tui/tui-win.c (tui_async_resize_screen): Clear win_resized
first before resizing the window.
* tui.c (tui_enable): Likewise.

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++.

If the user:
#1 - disables the TUI
#2 - resizes the terminal
#3 - and then re-enables the TUI
the next wgetch() returns KEY_RESIZE. This indicates to the ncurses
client that ncurses detected that the terminal has been resized. We
don't handle KEY_RESIZE anywhere, so it gets passed on to readline
which interprets it as a multibyte character, and then the end result
is that the first key press after enabling the TUI is misinterpreted.
We shouldn't really need to handle KEY_RESIZE (and not all ncurses
implementations have that). We have our own SIGWINCH handler, and,
when we re-enable the TUI, we explicitly detect terminal resizes and
resize all windows. The reason ncurses currently does detects a
resize is that something within tui_enable forces a refresh/display of
some window before we get to do the actual resizing. Setting a break
on ncurses' 'resizeterm' function helps find the culprit(s):
(top-gdb) bt

That is, tui_enable calls tui_set_key_mode before we've resized all
windows, and that refreshes a window as side effect.
And if we're already debugging something (there's a frame), then we'll
instead show a window from within tui_show_frame_info:

* tui/tui.c (tui_enable): Resize windows before anything
might show a window.

This patch fixes a pair of TUI issues related to screen resizing:
1. In tui_handle_resize_during_io(), when the TUI screen gets resized,
we fail to update GDB's idea about the height of the output window.
You can see this bug by doing:
a. Enter TUI mode.
b. "show height"
c. Resize the terminal.
d. "show height"
And observe that despite resizing the terminal, the reported height
remains unchanged. Note that a similar issue exists in the CLI.
The fix for this is simple: call tui_update_gdb_sizes() after performing
a resize, so that the "height" variable remains consistent with the
height of TUI's output window.
2. In tui_enable(), the call to tui_update_gdb_sizes() may clobber
readline's idea of the actual screen dimensions, and a subsequent
pending resize will use bogus terminal dimensions.
You can see this bug by doing:
a. Enter TUI mode.
b. Exit TUI mode.
c. Resize the terminal.
d. Enter TUI mode.
e. Press a key to resize the screen.
And observe that the terminal gets incorrectly resized to the wrong
dimensions. To fix this issue, we should oppurtunistically resize the
screen in tui_enable(). That way we eliminate the possibility of a
pending resize triggering right after we call tui_update_gdb_sizes().
gdb/ChangeLog:
* tui/tui-io.c (tui_handle_resize_during_io): Call
tui_update_gdb_sizes() after resizing the screen.
* tui/tui.c (tui_enable): Resize the terminal before
calling tui_update_gdb_sizes().

Older versions of ncurses' newterm can't take NULL for their ofp and ifp

that is the case.
This patch explicitly passes stdout/stdin to the call to newterm to
avoid segfaulting with older ncurses.

I noticed that with:

The next key the user types is silently eaten.
The problem is that we're throwing an exception while in a readline

PR tui/16138 is about failure to initialize curses resulting in GDB
exiting instead of throwing an error. E.g.:
$ TERM=foo gdb
(gdb) layout asm
Error opening terminal: foo.
$
The problem is that we're calling initscr to initialize the screen.
As mentioned in
http://pubs.opengroup.org/onlinepubs/7908799/xcurses/initscr.html:
If errors occur, initscr() writes an appropriate error message to
standard error and exits.
^^^^^
Instead, we should use newterm:
"A program that needs an indication of error conditions, so it can
continue to run in a line-oriented mode if the terminal cannot support
a screen-oriented program, would also use this function."
After the patch:
$ TERM=foo gdb -q -nx
(gdb) layout asm
Cannot enable the TUI: error opening terminal [TERM=foo]
(gdb)
And then PR tui/17519 is about GDB not validating whether the terminal
has the necessary capabilities when enabling the TUI. If one tries to
enable the TUI with TERM=dumb (and e.g., from a shell within emacs),
GDB ends up with a clear screen, the cursor is placed at the
bottom/right corner of the screen, there's no prompt, typing shows no
echo, and there's no indication of what's going on. c-x,a gets you
out of the TUI, but it's completely non-obvious.
After the patch, we get:
$ TERM=dumb gdb -q -nx
(gdb) layout asm
Cannot enable the TUI: terminal doesn't support cursor addressing [TERM=dumb]
(gdb)
While at it, I've moved all the tui_allowed_p validation to
tui_enable, and expanded the error messages. Previously we'd get:
$ gdb -q -nx -i=mi
(gdb)
layout asm
&"layout asm\n"
&"TUI mode not allowed\n"
^error,msg="TUI mode not allowed"
and:
$ gdb -q -nx -ex "layout asm" > foo
TUI mode not allowed
While now we get:
$ gdb -q -nx -i=mi
(gdb)
layout asm
&"layout asm\n"
&"Cannot enable the TUI when the interpreter is 'mi'\n"
^error,msg="Cannot enable the TUI when the interpreter is 'mi'"
(gdb)
and:
$ gdb -q -nx -ex "layout asm" > foo
Cannot enable the TUI when output is not a terminal

The TUI terminal state becomes corrupted (e.g. key sequences such as
Alt_F and Alt_B no longer work) when one attaches to an inferior process
(via "run" or "attach") from within TUI. This terminal corruption
remains until you switch out of TUI mode.
This happens because the terminal state is not properly saved when
switching to and out from TUI mode. Although the functions tui_enable()
and tui_disable() both call the function target_terminal_save_ours() to
save the terminal state, this function is a no-op unless GDB has already
attached to an inferior process. This is because only the "native"
target has a useful implementation of target_terminal_save_ours()
(namely child_terminal_save_ours()) and we only have the "native" target
in our target vector if GDB has already attached to an inferior process.
So without an inferior process, switching to and from TUI mode does not
actually save the terminal state. Therefore when you attach to an
inferior process from within TUI mode, the proper terminal state is not
restored (after swapping from the inferior's terminal back to the GDB
terminal).
To fix this we just have to ensure that the terminal state is always
being properly saved when switching from and to TUI mode. To achieve
this, this patch removes the polymorphic function
target_terminal_save_ours() and replaces it with a regular function
gdb_save_tty_state() that always saves the terminal state.
Tested on x86_64-unknown-linux-gnu by running "make check", no new
regressions.
