Dear list,
I only recently upgraded to Emacs 24 (since Debian Testing only recently
did that). I'm generally positive about the changes, but there's one thing
that irks me a bit, namely the new handling of I/O with inferior GDB
processes.
As I'm sure you're aware, Emacs 23 handled I/O with the debugged program
in the same buffer and with GDB itself, while Emacs 24 now handles it in a
separate buffer. I have two problems with this:
* It uses an extra window when debugging, where I'd rather use that space
for other things.
* It switches to that buffer whenever a program being debugged in the
background decides to print something. Since I often have a server
process running in GDB in the background that outputs log messages with
a few millihertz or so, it springs up randomly every now and then.
I solved the latter problem with a simple modification to the
gdb-inferior-filter function, but I'm still working on a solution to the
former problem. It seems to me that I could simply remove the following
three lines from gdb-init-1:
(gdb-get-buffer-create 'gdb-inferior-io)
(gdb-clear-inferior-io)
(gdb-inferior-io--init-proc (get-process "gdb-inferior"))
I feel like this is likely to have unintended side-effects, however. Is it
safe doing that, or will it confuse the communication with GDB somehow, or
something?
If there's no problem with this, I'll make a more proper patch of it with
customization later and submit it.
Thanks for reading!
