Not 100% sure if it is the same issue, but I can crash dillo by going to the bookmark page and then keep Ctrl-r pressed so that it reloads continiously. After a while I get a segmentation fault, but no proper stack unfortunately. Cheers, Johannes

The point is we have massive changes in the DPI area, not in dillo. If you trigger it while browsing HTTP, DPI is out of the equation. If it happens with HTTPS, DPI participates. I'd expect you not being able to trigger the bug by using the file dpi, but if you can with plain HTTP it's a surprise. -- Cheers Jorge.-

I dont't know any trigger yet. I just browse pages and occasionally the problem happens. There isn't any specific page either.

If you isolate a way to reproduce the bug, we may ask other *BSD users to test, and I'd have a hint of the code path. -- Cheers Jorge.-

EAGAIN loop in IO_read

by furaisanjin＠gmail.com

Hi all. This might be FreeBSD specific issue but I have EAGAIN loop in IO_read. I don't know anything yet why this happens but at some point read function keeps returning EAGAIN in IO_read and nothing is read. Do you have any idea how to investigate this further? I think this happens after DPI big change. Regards, furaisanjin

I have updated the scrolling patch, but came to the conclusion, that it is not a good idea - at least not in the way I did it originally: I have made the scrollbars part of the UI and ripped out the code that deals with scrollbar widths in layout.cc. But then I thought about frames, and there we potentially need scrollbars for every frame. So for now will leave things as they are and focus on fixing real bugs. Cheers, Johannes

The buffer size constraint and atomicity transfer hope (left to the OS) were removed. DPIP implementation handles it internally now. I was planning to work on the view source dpi a bit and at least advance it until the dpi gets the whole file so you can do the funny part. I can't but feel a bit guilty by the work you have put on it only to discover the framework was not up to the task. The DPIP framework grew by extending it to each new dpi needs, and there were constraints. This rewrite was necessary to make it more reliable in the concept, and not ad-hoc to the task. BTW, I still have to turn https into a server dpi to remove the dialog-storm bug, and to give a look into the cookies dpi to make it distinguish among different instances of dillo. View source is the first on the list, so if I were you I'd keep working on the scrolling patch and wait until Jorge commits. :) Or at your own choice let him finish the whole view source thing! -- Cheers Jorge.-

Dear Dillo developers, could anyone be so kind and build a Dillo package (with ssl enabled) and a FLTK2 package for the new Ubuntu version 9.10 Karmic Koala? Many thanks in advance, Alexander Voigt

For now I can just confirm that it works nice on DragonFly :-) Do you think it would be a good time now, to look into the view source dpi thing again? Cheers, Johannes

[patch]: fix the default <th> style to match <td>

Thanks, Johannes PS: There may be more glitches in the default user-agent style. Please report any strangeness.
