dillo_port1.3: segfault someplace on reload of news.google.com
by rogerx.oss＠gmail.com Aug. 5, 2011

Aug. 5, 2011

I've got a segfault using dillo_port1.3 by continuously hitting the Reload button with the following url: http://www.google.com/search?aq=f&hl=en&gl=us&tbm=nws&btnmeta_news_search=1… After about three or four taps, dillo disappears and I don't see anything within the debug output from the startx window. (Using DWM and manually starting startx within a terminal here.) I don't think I've compiled with -g, -ggdb, etc... but here's what I've got so far. I'll try to bit-bang this a little bit more tomorrow when I get time if nobody else gets this. My guess so far, when running within GDB, reload button works continuously without crashing until I start clicking before the page finishes reloading, then segfault. So, scanning gdb bt, this looks like it might get into fltk-1.3 buttons. This is all I've got so far: Connecting to 74.125.127.103 a_Nav_expect_done: reload!

style attr parsing surprise
by corvid＠lavabit.com Aug. 3, 2011

Aug. 3, 2011

CSS complained about "no values" for padding, and it turned out to be something like <element style="padding: 10px 15px"> Html_get_attr2() is removing the '\n' completely. It turns out that we're doing the right thing (whereas I expected it to be replaced by a ' ') because the style attr is %StyleSheet, which is CDATA, and we are instructed to "Ignore line feeds" for CDATA. But I'm writing this down anyway because it surprised me, and it's good to save this away in the list archives (which may well have a few variations on this already from years past). (Or is it coming to be time to admit defeat for html4 and start looking in the shocking endless immensity that is html5 when it comes to such matters?)

[patch]: map Ctrl-Shift-Tab instead of Shift-Tab to Left-Tab
by onepoint＠starurchin.org Aug. 3, 2011

Aug. 3, 2011

I know that you can do this by editing the keysrc but I think that by default Dillo should copy Firefox by using Ctrl-Tab and Ctrl-Shift-Tab to navigate among tabs and freeing Tab and Shift-Tab to navigate around the page. Patch attached. Comments? Should I push? Regards, Jeremy Henty

We have dillo-3.0 scheduled for release in August. (BTW, fltk-1.3 already made it into squeeze). Thanks for the update. -- Cheers Jorge.-

Questions about beta testing
by waltdnes＠waltdnes.org Aug. 3, 2011

Aug. 3, 2011

Hi all; I joined the list recently. It's been a long time since I last ran beta software consistently. Ironically, it was the Phoenix browser beta (later to become Firebird, and then Firefox). I was unhappy about how bloated the major browser had become, and I wanted a lightweight browser. It looks like I've come full circle. Iam not a C programmer. I'm a "power user" instead. I remember about extracting the tarball, going into its directory and then executing... ./configure --with-various-options && make && make install ...but that's about all. Like the subject says, I have some questions 1) I assume that all files that go into /usr/whatever in a normal install under a package manager, will end up in /usr/local/whatever if I build from the tarball. Is that correct? 2) How do I uninstall the program? Or can I simply install new versions over top of old ones? 3) Can I assume that the configure defaults are the reverse of the options? E.g. if the "configure" file has... --enable-ssl Enable ssl, https (ALPHA CODE) --enable-ipv6 Build with support for IPv6 --disable-cookies Don't compile support for cookies --disable-png Disable support for PNG images ...then are the defaults --disable-ssl --disable-ipv6 --enable-cookies --enable-png ? Which one is the default here? Hopefully the "enable" version. --disable-dependency-tracking speeds up one-time build --enable-dependency-tracking do not reject slow dependency extractors 4) I run Gentoo linux, in 64-bit mode on an Intel i3. The first 4 statements in my /etc/make.conf are... CFLAGS="-O2 -march=native -mfpmath=sse -fomit-frame-pointer -pipe" CXXFLAGS="${CFLAGS}" CHOST="x86_64-pc-linux-gnu" MAKEOPTS="-j1" I believe that CFLAGS and CXXFLAGS are read directly by gcc. Is CHOST used outside of Gentoo's package-management? And how do I pass MAKEOPTS to make? Yes, I know that "-j1" slows down the build process slightly. But the final binary is just as fast. And the first time you waste a couple of hours on mysterious failures during the build process, you lose all the time you "saved" with a higher "-j" value. I see it every so often on the Gentoo mailing list. Here is what I'm looking at to automate the build process... #!/bin/bash export CFLAGS="-O2 -march=native -mfpmath=sse -fomit-frame-pointer -pipe" export CXXFLAGS="${CFLAGS}" ./configure --enable-ssl && make && make install Any comments? -- Walter Dnes <waltdnes(a)waltdnes.org>

changing cursor, open() calls
by corvid＠lavabit.com Aug. 3, 2011

Aug. 3, 2011

I was running dillo under strace, and whenever the cursor moves over a link, out comes: open("/home/corvid/.icons/default/cursors/hand2", O_RDONLY) = -1 ENOENT (No such file or directory) open("/home/corvid/.icons/default/index.theme", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/share/icons/default/cursors/hand2", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/share/icons/default/index.theme", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/share/pixmaps/default/cursors/hand2", O_RDONLY) = -1 ENOENT (No such file or directory) open("/usr/share/pixmaps/default/index.theme", O_RDONLY) = -1 ENOENT (No such file or directory) ..and looks for an xterm cursor when over a Fl_Input, and then looks for things like open("/usr/share/X11/locale/compose.dir", O_RDONLY) = 4 open("/usr/share/X11/locale/iso8859-1/Compose", O_RDONLY) = 4 ..now and then when dealing with the toolbar or its tooltips or something. Maybe FLTK has a deep reason for this, but I would have expected it to make up its mind when it first needed all of this during execution.

style bug, perhaps
by corvid＠lavabit.com Aug. 3, 2011

Aug. 3, 2011

I reload the following, and the link border around the first image disappears. If the problem's in the style attr copying/comparison/etc., I'm failing to see it. I can see that the style has border type of none and border width of 0. I started to try to watch ":link img, :visited img {border: 1px solid}" get applied, but... <html> <body> <a href="whatever.html"> <img src="whatever.jpg"> </a> <button type='submit' name='button'"> <img src="something.jpg" alt="Search"> </button> </body> </html> BTW, Jeremy's valgrind logs have an interesting variety of 1.3 bugs for us now.

Images Not Updating (Using Cache on Page Reload)
by rogerx.oss＠gmail.com Aug. 1, 2011

Aug. 1, 2011

I just noticed, dillo_port1.3 using fltk-1.3 is not refreshing/reloading images when page Reload is pressed. The images I noticed not reloading are found on my weather forecast page: http://forecast.weather.gov/MapClick.php?zoneid=AKZ222 (... thinking, this might be more in depth such as the images being embedded in javascript or something which mitigates this issue.) -- Roger http://rogerx.freeshell.org/

What's pending in dillo-3.0 for a release
by jcid＠dillo.org Aug. 1, 2011

Aug. 1, 2011

Hi there, Fltk-1.3 is out there, and we've worked our pending issues list. What's still pending? BTW, I'm working on a focus bug (recently discovered): loading [1], and scrolling down with the down arrow key, makes the rendering area lose focus (taken by the selection list when it becomes visible), and mouse-clicking doesn't recover it.
