Has anybody had trouble with GWM losing > applications? It seems like the DEC implementation of Xlib is broken. We do not have DEC windows Xlib, so I just linked GWM with the MIT Xlib on a vaxstation, and I cannot reproduce the problem (I got the DEC SM and dxcalendar iconified and de-iconified). (PS: DEC seems to do very strange things with the Xlib, especially they seem to have included a "malloc" in the xlib !!! Anyone from DEC can comment?) This kind of problems may appear with GWM since it is an ICCCM compliant WM, and DEC didn't bother with ICCCM in DEC windows. For instance, GWM had problems with the BULL Xlib implementation since it always set the "window-group" hint to a garbage value... hard on WM! So: either: - run GWM on another machine - link it with the MIT Xlib - or send me a VAX (not pmax) binary of gwm compiled with '-g' and DEC Xlib so that I can have a look at the problem Colas NAHABOO -- colas@mirsa.inria.fr BULL Research FRANCE -- Koala Project -- GWM X11 Window Manager

Anyone from DEC can comment?) It turns out that the default malloc wastes huge amounts of space when you allocate memory that is a power of two bytes. It adds in the size of the header and then rounds up to the next power of two, thereby wasting almost half the bucket. Not surprisingly, lots of programs allocate things in powers of two! Our new malloc makes programs take considerably less space. Why didn't we just replace the system malloc? Don't ask... >This kind of problems may appear with GWM since it is an ICCCM compliant WM, >and DEC didn't bother with ICCCM in DEC windows. Geez! The ICCCM came out after DECwindows! We try to be responsive to standards but we're not psychic, you know. -paul asente asente@decwrl.dec.com decwrl!asente
