Errata and comments

by bogus＠does.not.exist.com

Hi, Errata: -./autogen.sh -make +./autogen.sh +./configure +make Comments: In the old laptop (Pentium I, 233Mhz) scrolling is much better with the patch. This is, without patch, the CPU is hogged by pressing the scroll arrow and holding it down. It even keeps scrolling after releasing the button (keyb buffer). The patched version uses near 80% of the CPU (not 100%) and stops when releasing. In the same laptop, the over-link-quick-switch-from-arrow-to-hand (i.e. Get a directory listing and move the mouse across the links steadily) rises CPU usage to near 60%. Thre's a bug somewhere... -- Cheers Jorge.-

New CVS repository and patches

by bogus＠does.not.exist.com

Hi There! Once again, thanks for the patches and keep them flowing. The new CVS repository is up and updated with the patches: e.g. (with "-cur" terminated directories being the working directories) alias dcvs='cvs -z3 -djcid@auriga.wearlab.de:/sfhome/cvs/dillo' dcvs co dillo2 dcvs co dw2 cp -r dillo2 dillo2-cur cp -r dw2 dw2-cur ln -s dw2-cur dw-testbed find dw2-cur -name CVS -exec rm \{\} \; find dillo2-cur -name CVS -exec rm \{\} \; cd dw2-cur ./autogen.sh make cd ../dillo2-cur ./autogen.sh make Here follow my comments on the patches. Please test this CVS code and send feedback: > [Johannes wrote] > * the namespace "signal" in dw-testbed/lout/signal.hh conflicts with > the declaration in /usr/include/sys/signal.h: > __sighandler_t *signal (int, __sighandler_t *); > I renamed the namespace to loutsignal. Johannes: please send me the patch for this. > [Vincent wrote (va_list issue)] > Sure, though i'm not at all sure this is the correct way to fix this > issue. Vincent: AFAIS, the problem is looping without the va_copy, so the patch is OK.

Alexander: as strndup is a GNU extension, and we have kept the code as portable as possible, I just added the wrapper for it based on the patch. With regard to Perl, I'd like to get rid of that dependence either with bash (if possible) or C. BTW, if Sebastian agrees it may also be a good idea to use Dlib in dw2. That way those problems could be layered down... > [Johannes wrote] > here is a new version of dillo-fltk scroll performance > improvements.

I also have a running glpuzzle. The CPU, hogs when scrolling on vanilla but not with the scrolling patch, and entities work. I also don't experience CPU-hogs from the over-link-quick-switch-from arrow-to-hand test. Maybe this is related to something not installed or not configured in your machine... (This system has: x11proto-gl-dev, freeglut3, freeglut3-dev, libxft2, libxft2-dev, libgl1-mesa-{dev,dri,glx} among others that I don't know whether relevant or not! ;).

This number is a good candidate. ---------------- Side Note to all: Have you right-clicked over the search button? :-) -- Cheers Jorge.-

It seems to depend on how large the textblock is that I move over. Commenting out Textblock::motionNotifyImpl() made no difference, and I don't know the upstream code well enough yet to chase down the problem efficiently...
