dw::Table valgrind-friendliness
by onepoint＠starurchin.org March 2, 2008

March 2, 2008

Dillo has been neglecting its valgrind cleanliness recently and it turns out the culprit is dw::Table, which resizes its internal vectors without initialising any new values that appear. If you valgrind dillo and immediately close the splash window, valgrind reports 121 "Conditional jump or move depends on uninitialised value" errors! This patch reduces that number to 2!

Fixed a mistake in the CSS-box-model PNG image (style-box-model.png).
by jcid＠dillo.org March 2, 2008

March 2, 2008

Hi, I just committed this fix. The wrong documentation image mislead me a lot while working on the redraw problems. Now it's accurate (CSS box model in namespacedw_1_1core_1_1style.html). -- Cheers Jorge.-

patch: multipart/form-data encoding for form submission
by place＠gobigwest.com March 2, 2008

March 2, 2008

Currently, dillo always submits forms using url encoding regardless of the encoding specified by the form. Wikipedia, for example, specifies multipart/form-data because the user may submit huge blocks of text in languages where url encoding will be very inefficient. - This patch always uses the same boundary, but a different one REALLY should be used for every form submission. At the least, the string should be scrambled up somehow. - It adds a URL_MultipartEnc flag. - For the Content-type header, I pull the boundary out of URL_DATA because I didn't want to clutter up the URL with a field for something not commonly used. ----------------------------------------------------------- For multipart/form-data, a submission goes like: [headers] Content-type: multipart/form-data; boundary="[boundary]" --[boundary] Content-Disposition: form-data; name="[name1]" [value1] --[boundary] Content-Disposition: form-data; name="[name2]" [value2] --[boundary] ...and eventually... Content-Disposition: form-data; name="[namen]" [valuen] --[boundary]--

What shall we do with the buggy RFC?
by onepoint＠starurchin.org March 1, 2008

March 1, 2008

Dillo is buggy because RFC2396 is buggy! An outrageous claim, I know, but hear me out! The problem appears when resolving a relative URI reference such as "?foo=bar" relative to a URI such as "http://a.b.c/e/f". Dillo resolves this to "http://a.b.c/e?foo=bar" ie. it loses the last path component. This is clearly wrong, and it breaks pages such as http://www.guardian.co.uk/business/gallery/2008/jan/18/1?picture=332092597 (trying clicking on the big picture - you won't get the next one in the gallery). Clearly Dillo should only lose the last path component of the base URI when the path of the relative is non-empty. Nevertheless, this broken behaviour *is* RFC compliant! If we study the 7 steps in "5.2. Resolving Relative References to Absolute Form" of RFC2396 we see a problem in step 6, which begins: a) All but the last segment of the base URI's path component is copied to the buffer. In other words, any characters after the last (right-most) slash character, if any, are excluded. So we are instructed to lose the last path component in all cases. Unfortunately we get to step 6 if the URI reference is "?foo=bar". Hence the breakage. Patch attached. Jeremy Henty

[patch] redraw optimization now including tables
by Johannes.Hofmann＠gmx.de Feb. 29, 2008

Feb. 29, 2008

Hello, below is an improved version of the redraw optimization. It now also covers table based pages - at least to some point. The challenge is to make the already commited optimization work recursively. Other than I originally thought topLevel is always a Textblock. Table based pages simply consist of a Textblock with a huge Table as child widget. Textblock now needs to avoid redrawing the child area when the table size increases. The redrawing is left to the Table-code, which then can be optimized. Please test carefully and report any anomalies you find. Regards, Johannes
