removeIdle: *** [unknown] This should not happen! *** Aborted
by place＠gobigwest.com March 26, 2008

March 26, 2008

I think I mentioned this problem some time ago, but playing with ComplexButton makes it much worse (when meta charset causes a repush). The backtrace shows that it's unhappy because IdleFunc doesn't have an equals(). To make the problem go away, I changed the remove in FltkPlatform::removeIdle() to a removeRef, but, again, I don't know this code well enough to know what should be going on. #0 0x40344c81 in kill () from /lib/libc.so.6 #1 0x401b04a1 in pthread_kill () from /lib/libpthread.so.0 #2 0x401b087b in raise () from /lib/libpthread.so.0 #3 0x403448f8 in raise () from /lib/libc.so.6 #4 0x40345f00 in abort () from /lib/libc.so.6 #5 0x0809e054 in misc::assertNotReached () at misc.hh:67 #6 0x080ad6f1 in object::Object::equals (this=0x81ab118, other=0x81ab118) at object.cc:49 #7 0x080aa182 in container::untyped::List::remove0 (this=0x81c1b90, element=0x81ab118, compare=true, doNotDeleteAtAll=false) at container.cc:254 #8 0x080891c7 in container::untyped::List::remove (this=0x81c1b90, element=0x81ab118) at ../lout/container.hh:169 #9 0x080891eb in container::typed::List<dw::fltk::FltkPlatform::IdleFunc>::remo ve (this=0x81c1960, element=0x81ab118) at ../lout/container.hh:376 #10 0x08086968 in dw::fltk::FltkPlatform::removeIdle (this=0x81c1b68, idleId=1) at fltkplatform.cc:319 #11 0x0809feaa in ~Layout (this=0x81c1bf8) at layout.cc:117

I see the convenience and clarity of passing two parameters instead of three, but on the other hand, keeping APIs reduced to a functional minimum, helps to remember and to choose the right function call. There may be a point I don't yet see... -- Cheers Jorge.-

https plugin status
by Christian.Kellermann＠nefkom.net March 24, 2008

March 24, 2008

Dear list, is the https plugin supposed to work? Whenever I select a https URL dpid gets started but nothing happens whatsoever. I do have SSL enabled and all. I am aware that there is some work needed and that https support is considered as very basic. But what is supposed to be working atm? It is easier to fix bugs if you know what it should look like...

multiple-scan images consume a lot of CPU
by Johannes.Hofmann＠gmx.de March 20, 2008

March 20, 2008

Hi, I really like the multiple-scan image feature added to dillo recently, but it uses quite some CPU and makes it drag slow when going back and forth on pages with a lot of images. So as the "TODO" comment in jpeg.c already suggests, we need some way to switch off multiple-scan when the image is readily available either from cache, from disk, or from a fast network connection. I think some sort of rate limiting would be best that restricts rescans to - say - once a second. What do you think? Cheers, Johannes

[patch] further reduce redraws from resizing tables
by Johannes.Hofmann＠gmx.de March 18, 2008

March 18, 2008

Hi, below is another patch to reduce the redraws caused by resizing tables. A new method Layout::queueDrawExcept(), that requests the drawing of a rectangle except another rectangle is added. It is then used in widget.cc to redraw the area that was previously occupied by a widget, but is no longer occupied after a resize or move. This makes it possible to redraw less when a table resizes. All in all it should reduce the flicker a bit when loading table based pages.
