patch: URL data as a Dstr
by place＠gobigwest.com March 29, 2008

March 29, 2008

This is part one in a series for file inputs. Parts two and three are written. Parts four and five are contemplated. Maybe a part six if I feel like it. Part three is the one that makes it at least appear to work, though I'll need help in testing at that point. HTTPS note: If https does remain a dpi, somebody will have to decide what they want to do with Capi_dpi_build_cmd() if http_query can contain NULLs.

ComplexButton crashing
by place＠gobigwest.com March 26, 2008

March 26, 2008

For you dw people... I am working on getting ComplexButton to work (image inputs), and it would segfault when I'd close the bw. In FltkComplexButtonResource::createNewWidget, the button's child is a view. When the button is destroyed, since the button is a Group, its children get destroyed. Later on, the layout is being destroyed, and it deletes TopLevel. The toplevel widget destructor calls layout->removeWidget(), which tries to iterate through the views. To make the problem go away, I added: fltkcomplexbutton.hh: ~ComplexButton() {remove_all();} but I don't know any of this code well enough to know what _should_ be going on.

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...

I've been missing the occasional message lately. I do not have any spam filtering. Does whoever admins the list have any insight?

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
