I hadn't looked at that specifically. Let's see... To avoid duplicating the big case statement, I'd want to make a char *Html_get_input_value(input) { switch (input->type) { ... } return value; } if (ENC_MULTIPART) { for (each input in the form) { value = Html_get_input_value(input); dStr_append(data, name); dStr_append(data, value); } ...boundary... etc. ... } But for a file input, it could have embedded nulls, so make Html_get_input_value() return a Dstr* instead. Okay. But for an image input, thanks to clickpos, I'd have to make it return a list of name/value pairs. Maybe that's not too bad, but it does put me in a bit of a "stupid HTML and its stupid special cases!" mood. Random thought: I wonder whether url->data gets eradicated after sending somehow, or if copies of it stick around in copies of the url on, I don't know, the nav stack or whatever. If there are copies floating around, that'll be no fun if they were each to contain a big file input in their data. > PS: I usually manually delete the CC of my replies to you, thinking > that you'll get it from dillo-dev. Do you want the extra copy? I know someone who, when cc:ed, tends to say "I read the list" :)

Have you tried something like?: </pseudocode> Html_submit_form2() ... if (ENC_MULTIPART) { append every single "name" "value" pair into a Dstr do { make boundary } while (strstr(Dstr, boundary) || maxtries); } ... encode as usual. </pseudocode> If yes, why does it fail? -- Cheers Jorge.- PS: I usually manually delete the CC of my replies to you, thinking that you'll get it from dillo-dev.

I'm not proud of this code, but special cases were getting in the way of attempts at cleanup.

So the partial optimization seems to > be working. Yes, the patch only tries to avoid redraws that change nothing on the screen. For complex tables that get rearranged all the time while loading, there is still a lot of redraws. However there is certainly room for improvement. For the fun of it, you can comment out the lines in table.hh where redrawY gets reset. That saves a lot of redraws at the cost of some anomalies... > > > The challenge is to make the already commited optimization work > > recursively. > > Do you want me to commit this new patch, or to keep the already > committed one? > > > > Other than I originally thought topLevel is always a > > Textblock.

If the resizing does not change anything that is actually drawn by the Textblock (like real text), it does not need to request a redraw. > > From a distance it looks like a conditionalRedraw() may be the needed call > (I don't know well what expose means). I mean if this conditional redraw > sees that nothing has changed in the specified area, it can simply return, > otherwise redraw. Yes, that's the idea of the new virtual method resizeDrawImpl(). Each widget can remember what has already been drawn and what might have changed because of resizes and then draw only the necessary parts. It depends on each widget how careful it is. Tables have the unfortunate property of changing their layout all over when new cells are added thereby requiring complete redraws. > > > > The redrawing is left > > to the Table-code, which then can be optimized. > > Please test carefully and report any anomalies you find. > > I haven't found any anomalies. :-) Excellent.

AFAIU textblock draws by lines and as the first line is a huge table it requests a redraw of it. I don't know yet why textblock is requesting a redraw; I assume that as the table size changed, textblock gets notified and as it doesn't know better it asks the child widgets for a full redraw. From a distance it looks like a conditionalRedraw() may be the needed call (I don't know well what expose means). I mean if this conditional redraw sees that nothing has changed in the specified area, it can simply return, otherwise redraw. > The redrawing is left > to the Table-code, which then can be optimized. > Please test carefully and report any anomalies you find.
