what's currently broken in dillo

by james.from.wellington＠gmail.com

I'm not sure when it started, but I'm getting this: [dpip]: [Dpip_dsh_write] Broken pipe [dpip]: [Dpip_dsh_write] Broken pipe [dpip]: [Dpip_dsh_write] Broken pipe [dpip]: [Dpip_dsh_write] Broken pipe [cookies dpi]: (pid 27897): Got DpiBye. [cookies dpi]: Cookies saved: 0. [cookies dpi]: cleanup [dpid]: terminated normally (0) with no obvious preamble. I'm running the hack-up that I sent to the list, with a new parser for dpidrc, which prevents it from timing out on the normal time-scale. Regards, James.

Problem with page positioning.

by james.from.wellington＠gmail.com

Peripheral to the original issue, preserving smooth behavour of a form across a re-render would be an interesting (possibly in a slightly hair-pull way) problem. The content of fields, cursor position, and keystrokes received during the re-render, would all have to be preserved. I'm not volunteering. Regards, James.

I do not understand your logic. Waiting for the CSS prior to rendering the page, does not forbid switching CSS off, as you described. Both features can co-exists without any conflict. My logic is that if the CSS files loads so slow as you describe (I still think it is a very, very rare case that can not rule the whole design), it is not important whether the rendering will happen twice or once - the page still will be not usable at all and you will need to disable CSS in order to get some usability at all. Notice, that nothing changes for your mentioned site, but on the normal, fast web sites, the screen flicker will be removed at all. -- http://fresh.flatassembler.net http://asm32.info John Found <johnfound at asm32.info>

If the current implementation is fine, you should not disable CSS, but you could work on these forms on the first rendered screen (without CSS) and to continue to work transparently when the page refreshes after the CSS get Forms are disabled so that you cannot enter data when there is still css to load. So I have to disable CSS if I do not want to wait ages in theese cases. BTW: What was the reason for that behaviour? > loaded. Your need to disable CSS proves exactly my theory: The first, fast, CSS-less rendering is useless at all and only provides screen flickering. So a blank screen is your preferred way to fill out forms or should I rather wait some minutes before starting to work on the page? I do not understand your logic. As you write in your other mail, some more intelligent solution might help, like wait 2 seconds and if css is not there, display what is displayable, so no flickering with good internet connection and no site problems.

But IMHO, there are some arguments for the opposite: If the page is already received (at least partially) there is very big probability that the CSS files (if they are on the same web site) will be delivered successfully and approximately in the same time range. If this time is small enough, why not to wait a little in order to get better user experience (not flickering pages). There is some network performance limit, where rendering the page twice will be slower than waiting for the CSS files and rendering once. As long as with the time the network performance increases and with the Dillo supporting more and more HTML features, the rendering speed is expected to decrease, then this wait for the CSS files probably will be implemented one day. This way IMHO, some more complex logic (and probably some heuristics) could improve the overall performance. At least, this feature deserves dillorc option. :) > I'd like to look at it but currently work on a resize/redraw bugs fills > my time. > Take your time! You are doing great work in all cases.

Before CSS, there was only one scroll offset, now there may be many (as many as different stylesheets the page has. A ridiculously large number sometimes, I *must* add). > Another question is why not to render the page only after the CSS files are > received (or the receive failed)?

Let's say you set the fail timeout to 30 seconds... Can you imagine it? Now if the page has let's say 7 stylesheets. Which compete with the main page, and dozens of images for bandwith, add the "temporary unavailable" answers, or simple fails that need a retry which some servers use to avoid bots wasting BW, or peak usage hours, etc. Then, how many do we expect before drawing? The point is: there're plenty of factors. Now, AFAIR, we've had a scroll-to-anchor-bug for a long time (another one which relates to a race condition while the canvas grows). This one looks simpler (may be the same though). I'd like to look at it but currently work on a resize/redraw bugs fills my time. -- Cheers Jorge.-

But simply commenting out the lines 307 and 308 in "nav.c" and recompiling I got the proper behaviour of the scrolling. The big question is what I have broke by this "solution"? :) Another question is why not to render the page only after the CSS files are received (or the receive failed)? Yes, it will slow down the first appearance of the page, but this first appearance is actually fairly useless for the most of the pages and only makes some flicker on the screen. -- http://fresh.flatassembler.net http://asm32.info John Found <johnfound at asm32.info>
