Mouse Wheel 80-90% slower then Seamonkey?
by rogerx.oss＠gmail.com Sept. 26, 2011

Sept. 26, 2011

Anybody else notice the mouse wheel is slow within Dillo? Comparing dillo_port1.3 to Seamonkey, dillo_port1.3 is almost 80-90% slower compared to Seamonkey. Comparing dillo_port1.3 to dillo, dillo_port1.3 is slower by approx. 50%. -- Roger http://rogerx.freeshell.org/

It seems that libpng is up to 1.5.0 now, so it's time to rip out some version tests.

Valgrind errors from downloads.cc
by onepoint＠starurchin.org Feb. 7, 2011

Feb. 7, 2011

Valgrind is reporting uninitialised data in DLItem::update() in downloads.cc[1]. Here's the code with the offending lines (705, 706) marked. /* Rate */ if (csec >= 2) { tsec = (float) (curr_time - twosec_time); ! rate = ((float)(curr_bytesize-twosec_bytesize) / 1024) / tsec; ! snprintf(str, 64, (rate < 100) ? "%.1fK/s" : "%.0fK/s", rate); prRate->copy_label(str); prRate->redraw_label(); } I'm wondering what is happening here. DLItem::update() is scheduled to be run every second. I think that twosec_time is only set to an initialised value when the function has been run at least twice before. Also, csec is calculated from the difference between the current time and the initial time. Is it possible that the "csec >= 2" could be true even when the function has been run only once before? After all, the timing of callbacks is never exact. Perhaps the callback should explicitly count how many times it has been called rather than attempt to work it out from the timing?
