[patch]: html.cc: change Html_add_input() to HtmlForm::add_input()
by onepoint＠starurchin.org May 29, 2008

May 29, 2008

This changes the Html_add_input() function to an HtmlForm::add_input() method. As before I'm submitting this as a "change diff" + "move diff" to make it easier to review. Reviewers please tell me if it makes things harder instead! Regards, Jeremy Henty

[patch]: html.cc: change Html_make_multipart_boundary() to DilloHtmlForm::make_multipart_boundary()
by onepoint＠starurchin.org May 28, 2008

May 28, 2008

More of the same. I'll hold off sending any more patches until these three have been reviewed. (Especially since I just remembered Jorge will probably want to camelCase the method names. D'oh!) Regards, Jeremy Henty

[patch]: html.cc: rename Html_build_query_data() to DilloHtmlForm::build_query_data()
by onepoint＠starurchin.org May 28, 2008

May 28, 2008

Does what it says on the tin! There's no "move diff" for this one due to declaration order dependencies. I expect the move will happen after the functions that access DilloHtmlInput internals are converted to DilloHtmlInput methods. Regards, Jeremy Henty

html.cc: convert Html_*_reset functions to methods
by onepoint＠starurchin.org May 28, 2008

May 28, 2008

This changes Html_reset_form() to DilloHtmlForm::reset() and Html_reset_input() to DilloHtmlInput::reset() . It's part of the plan to move code that accesses DilloHtmlForm and DilloHtmlInput internals into methods and make the internals private. The patch is in two parts: the first makes the changes and the second moves the new methods to the right place in the file. If I roll the changes and the move into one then "diff" gets confused and creates an unreadable monster of a patch. I'd recommend feeding the two attachments to patch separately; it might do the right thing given the whole message in one go, but then again it might not. Comments are welcome. There are several other functions in html.cc that are really just methods in disguise and are future targets for the same treatment as Html_reset_form() and Html_reset_input() get here. Regards, Jeremy Henty

html.cc: small tweak for consistency and debugging
by onepoint＠starurchin.org May 27, 2008

May 27, 2008

This renames a local variable from "size" to "nf". This is consistent with the names of similar local variables elsewhere in the file and also ensures that the _MSG statement will compile if debugging is enabled. Jeremy Henty

Re: (working) prototype of charset decoding in cache.c

I've made a second review over the code, and it doesn't look that bad to me. This is, the decoding in cache, even the stuffed cache-entry; if it can be isolated/tidied in the future better. The part that looks inconvenient to me is the charset choosing dialog. I'd prefer Dillo do this automatically. There's no need to try to recognize every charset in the world, but just a few "most used" ones like koi8-r. BTW, UTF-8 has become the preferred solution. The idea is that we can leave space for a expandable function just in case. BTW, there's an improved version of the data guesser in the ftp dpi. Please send me a koi8-r encoded page to test (or just let me know how to find it with google :). IIRC you sent me an explanation message on what this patch was for and remaining issues. I can't find it :(. Please resend it to me. > > There are plenty of issues. Going in order through the diff: > > - *_get_content_type().

The problem with "unknown as text" is that some HTTP servers send downloadable files as text. It is quite practical in this case to get a download dialog from dillo, intead of a binary rendering (especially for newbies). That's why the current data guesser is conservative. The data guesser can be improved. e.g. taking ASCCI control characters as a strong indication of a binary, and their absence as a text hint.

Consistency should be our goal/horizon/friend/helper. :-) -- Cheers Jorge.-

[patch]: html.cc: DilloHtmlForm::getCurrentInput()
by onepoint＠starurchin.org May 27, 2008

May 27, 2008

This refactors DilloHtmlForm code into a new "inline DilloHtmlInput *getCurrentInput()" method. It's just like the earlier patch that created DilloHtml::getCurrentForm() . Comments are welcome, although I hope it is uncontroversial. Regards, Jeremy Henty

an experiment in widget coloring
by corvid＠lavabit.com May 27, 2008

May 27, 2008

I saw a page that reminded me that the matter of when to have light text vs. dark text on widgets was not decided. earlier discussion: http://lists.auriga.wearlab.de/pipermail/dillo-dev/2008-February/003760.html trimmed-down bit of the page I saw: <form> <table bgcolor="#F8C473"> <tr><td> <input type="submit" value="I can hardly see the text"> </table> </form>

[patch]: html.cc cleanup: DilloHtml::currentForm()
by onepoint＠starurchin.org May 26, 2008

May 26, 2008

This patch adds a DilloHtml::currentForm() method and uses it to refactor wherever possible. This reduces the number of instances of the "foo->size() - 1" idiom in html.cc from 23 to 13! Regards, Jeremy Henty

[patch] dw2 memory reduction
by Johannes.Hofmann＠gmx.de May 26, 2008

May 26, 2008

Hi, attached is patch to reduce the memory usage of dw2: * Styles are now reused if they are equal. This brings down the number of Style objects on the mysql page from around 180000 to 23000 and reduces memory usage by about 25M at the cost of an additional HashTable. Maybe the hash table should be part of fltkplatform as the hash tables for Color and Font? There would be even more sharing of styles possible, if x_link would not be part of style. On the other hand about 3M for styles on the huge mysql page is pretty ok. * Size of struct Word is reduced by 4 integers by using shorts. I know that this is questionable, but I think in the case of struct Word that can be allocated a lot it is worth the hassle. Please check whether my assumption that space lengths and word lengths can be stored in shorts are valid in general. * SimpleVector no longer preallocates memory if it's not necessary. This actually saves some megabytes here! With these changes memory usage on the mysql page is 179M here. Cheers, Johannes
