Crosscompiling Dillo2 for uClinux on Blackfin
by heisermi＠hs-albsig.de Aug. 12, 2009

Aug. 12, 2009

Hi guys, Currently I'm searching for a small footprint webbrowser to use on my blackin device. This device is driven by uClinux. The first positive I can tell you is, that I compiled fltk2 for blackfin with success. I followed the instructions on tw.myblog.yahoo.com/stevegigijoe/article<http://tw.myblog.yahoo.com/stevegigijoe/article?mid=138&prev=-1&next=137> to compile and run fltk2. My modifications can be read at https://blackfin.uclinux.org/gf/project/uclinux-dist/forum/?_forum_action=F… So now I'm facing a problem with the configure script of dillo. I had to make few changes to configure.in to recognize crosscompiled Fltk2 lib. These changes went ok but when configure checks libz, then it crashes because it can't find right version of the library. So my question is, how can I tell configure to search in my uClinux directory where the library already is persistent for use with uClinux. Best Regards from Germany, Michae

If there is a handheld style sheet available and dillo is running on a handheld, it would be a shame not to use it. I'm hoping that the page author would have the sense to supply something for type "all". > Maybe it's more practical to provide custom stylesheets (as the > current "style.css". e.g. small_screen.css, print.css) and to > allow switching among them from the "Tools" menu. > > What do you think? I think someone using handheld would want to use both the page author's handheld-specific code and a user style suitable for their device. I'll send this to the list in case anyone with experience using such devices with the web has opinions to share.

Usually if I have a window partially hidden, I don't want it raised... Apps should not try to do their own window management." fltk's Window::handle() has: #if USE_X11 case PUSH: // Unused clicks should raise the window. Windows unfortunatly // raises the window on *all* clicks so we don't bother except on X. if (shown()) XMapRaised(xdisplay, i->xid); #endif Aforementioned patch attached.

experimental patch: Re: dillo2 wrapping Chinese
by corvid＠lavabit.com Aug. 2, 2009

Aug. 2, 2009

I made yet another version of this patch the other day, and furaisanjin was kind enough to run on it a bit and ensure it's doing what we want. With the previous version, compiling without optimization, gprof showed 3-4% loss of speed on a page that's mostly English text. - I removed the strdup/free from the common case. - For nonideographic, it goes character by character instead of checking every byte. This should help for, e.g., Russian, but means some 'unnecessary' length-checking in the mostly-ASCII case. And gprof suggested the slowdown might be 3% now, although at this point, unless someone is paying you to perform a lot of careful, drudgery-filled runs, it gets hard to pick the signal out of the noise when examining the time spent in relevant functions. I tried adding in some code to bypass the ideographic call for ASCII, but 1) it made the code a little messy 2) it looked like it might be saving a few tenths of a percent 3) the compiler might perform optimizations under certain circumstances making my efforts unnecessary or counterproductive. I could definitely be talked into this one, though. I tried adding an addText() with a length argument and thought it might help by saving me the trouble of writing NULL bytes into the strings and saving the trouble of some strlen()ning in dw. I couldn't see any difference in speed, although it did make things cleaner and I would want to add it in eventually if this all makes it into the repository. There will be a duplicated ideographic() test, for instance, if a word starts with digits and ends with some Japanese characters. 1) uncommon 2) complexity This patch is really two patches because it also handles the case where whitespace numeric character references are inside a word, but I wanted to see the effects of both and they are each an excuse for the overhead of the loop. I'd split it into two pieces if committing it.

dIsspace
by corvid＠lavabit.com July 27, 2009

July 27, 2009

When are we supposed to use isspace() and when are we supposed to use dIsspace()? It appears that one is now used in the C++ code and the other in the C code, but I don't know the reason for this distinction.

exit codes
by corvid＠lavabit.com July 24, 2009

July 24, 2009

I checked what bash sees when dillo returns -1 for bad cmdline argument, and $? shows 255. It seems that out of range values turn into 255. Not that anyone will ever care beyond zero vs nonzero, but I'd like to change it to something valid. I could change it to 1...or 2...or I could use the values from sysexits.h (i.e., borrow their values as opposed to including it, since it doesn't appear to be standard). Any opinions?

Problem: Dillo2 does not recognize True Type font
by ericshliao＠gmail.com July 19, 2009

July 19, 2009

I built dillo2 for my Debian5 desktop and found that Chinese text were not correctly displayed. All Chinese glyphs are displayed in empty blocks. I found that it's because the dillo2 that I built only recognized type1 font and did not recognize truetype font. I did a small test as the stated in the following to find the cause. I know it is not normal, because people don't have such problem. I wonder if this problem can be solved by setting proper ./configure options or by modifying Makefile. If you have any idea, please help. Thanx. At first, I suspect that FLTK2 does not support multi-national language dispaly. So I wrote a small program to test it. I used: "g++ -o fltkhello1 fltkhello1.cxx -I/usr/local/include -L/local/lib -lfltk2 -lXext -lXft -lX11 -lXi -lm" to compile. The result is not not satisfying. With the help from fltk-dev mail list, I tried "fltk2-config --compile fltkhello1.cxx" and got correct result. In fact, "fltk2-config --compile fltkhello1.cxx" will execute the following command to compile: gcc -I/usr/local/include -I/usr/include/freetype2 -Wno-non-virtual-dtor -o fltkhello1 fltkhello1.cxx -L/usr/local/lib /usr/local/lib/libfltk2.a -lX11 -lXi -lXinerama -lXcursor -lXft -lpthread -lm -lXext -lsupc++ The interesting part is: my previous faulty compile command made my program only recognize type1 font (such as Bitstream Charter), and no truetype font is recognized. The problem was corrected by calling "fltk2-config --compile fltkhello1.cxx". Because in my desktop, all the Chinese glyphs are provided by truetype font, it caued FLTK2 program won't dispaly Chinese glyphs. I also add some code in Dillo 2 source code to hardcode fontname to be used to draw text, I found that only typ1 font was recognized, all truetype fonts are not recognized.

Hi, I was getting frequent https.filter.dpi with dpip_tag == NULL. Attached patch adds a check for that case. If nobody objects I'd commit this in a few days. Cheers, Johannes
