Stuff Michael Meeks is doing

SUSE rock-star Michael Matz made my whole month with his three line gdb patch to make debugging un-instrumented x86 binaries work again; nice.
Gave up on hoping that Gnome would serve my blog sanely - apparently asking for it is a denial of service attack. Duplicated it at http://www.go-oo.org/~michael/blog/index.atom.

To further confirm Michael Matz is my hero - I did a comparison of OO.o debugging. OO.o is interesting because the debuginfo package you need is 275Mb small - but of course, you actually need rather more than that: the glib debuginfo package and various other pieces. Here is the trace before the patch:

(gdb) bt
#0  0xffffe430 in __kernel_vsyscall ()
#1  0xb6eb21d7 in *__GI___poll (fds=0x8641990, nfds=6, timeout=599) at ../sysdeps/unix/sysv/linux/poll.c:87
#2  0xb554f6f2 in ?? () from /usr/lib/libglib-2.0.so.0
#3  0x08641990 in ?? ()
#4  0x00000006 in ?? ()
#5  0x00000257 in ?? ()
#6  0x08641990 in ?? ()
#7  0x00000006 in ?? ()
#8  0x00000000 in ?? ()

And afterwards:

(gdb) bt
#0  0xffffe430 in __kernel_vsyscall ()
#1  0xb6eb21d7 in *__GI___poll (fds=0x8641990, nfds=6, timeout=599) at ../sysdeps/unix/sysv/linux/poll.c:87

Save your download bandwidth quota (and the planet too) by grabbing a new gdb for your OpenSUSE 11.0 from here.

Discovered & filed a juicy gcc -Os crasher. Lunch - Tina and children visiting, good to meet her. Back to work, mail to chew. Finally got around to writing up some of my thoughts on how to make the OO.o Community Council more relevant, representative and frankly interesting to people, that Louis asked for; posted for discussion, though missing the drawings. Call with Kelli.

I encourage linking back (of course) to help people decide for themselves, in context, in the battle for ideas, and I love fixes / improvements / corrections by private mail.

In case it's not painfully obvious: the reflections reflected here are my own; mine, all mine ! and don't reflect the views of Collabora, SUSE, Novell, The Document Foundation, Spaghetti Hurlers (International), or anyone else.
