I'd prefer GotHeader because that's what Cache_process_queue() tests for, and thus Data doesn't become an implicit flag. > I think it's all right for me to put that Cache_process_queue(entry) inside > an entry->Data test -- at least I couldn't find anything bad happening. BTW, funny as it may seem, I don't yet know what data unref you're talking about! :-) -- Cheers Jorge.-

[patch]: simplify a_Html_form_event_handler()
by onepoint＠starurchin.org May 29, 2008

May 29, 2008

The a_Html_form_event_handler() function displays an amusing anti-pattern (which I wish I knew the name of) where it's not given enough data and has to go searching for the missing information. Specifically, it gets a pointer to the DilloHtml of the page, but not not the DilloHtmlForm that submitted it, so it has to search the form list of the DilloHtml to find the form. This patch passes the DilloHtmlForm to the handler and adds a pointer from the DilloHtmlForm to the DilloHtml , so the handler can now directly access the form and the html without messing around.

[patch]: convert Html_submit_form2() to DilloHtmlForm::buildQueryUrl()
by onepoint＠starurchin.org May 29, 2008

May 29, 2008

The function Html_submit_form2() does two jobs rolled into one: most of its code creates a url from a DilloHtmlForm and a few lines push the url to a DilloHtml . This patch takes advantage of the fact that Html_submit_form2() is only called from a_Html_form_event_handler() ; it moves the url push out into the caller and the rest of the code into a new method "DilloUrl *DilloHtmlForm::buildQueryUrl()". This separates concerns nicely: the DilloHtmlForm creates the url and a_Html_form_event_handler() pushes it to the DilloHtml . We're getting close to having a proper API for DilloHtmlForm , unfortunately some of the remaining code is very messy. I'll do the rest of the easy stuff and then summarise what's left.

Previous patches a la camelCase

In case Jorge prefers them, here are revised versions of today's patches with camelCased method names. Regards, Jeremy Henty

[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.-
