Description Gustavo Noronha (kov) 2009-05-18 06:28:06 PDT
Currently WebKitGTK+ is limited to using identity as content encoding. We are unable to take advantage of compression, for faster transfer rates, for instance. See https://bugs.webkit.org/show_bug.cgi?id=25854 and http://bugzilla.gnome.org/show_bug.cgi?id=522772 for more information.

OK, since real Content-Encoding support is probably not coming until GNOME 2.30, and we're continuing to trip over sites that use "Content-Encoding: gzip" even though we send "Accept-Encoding: identity" (notably archive.org), maybe a gross hack is in order... what we'd do is, check from gotHeadersCallback if the response includes "Content-Encoding: gzip"; if so, disconnect from content-sniffed and got-chunk and connect to got-body. Wait until the got-body handler is called, unzip the body data all at once, call soup_content_sniffer_sniff() if necessary, and then belatedly emit all the webkit "signals". This would break incremental rendering of the data, but it would only be getting used on broken sites anyway.

I have been thinking the same. Are you planning to write such a patch, or should I try to secure some time to get it done?
Comment 7 Dan Winship 2009-10-21 11:04:57 PDT
i was not planning to write it myself
Comment 8 Dan Winship 2009-10-23 05:17:54 PDT

I just wanted to let you know in case you didn't see it in the gnome bug posted in the first message that support for proper content encoding should be released soon with libsoup-2.28.2.  There is also a patch there that supposedly enables these features for webkit.

Created attachment 44968 [details]
patch to use SoupContentDecoder

(note that while this claims to require libsoup >= 2.28.2, i haven't actually updated the gnome-2-28 branch yet, so you'll want to test against master. that will be fixed before this gets committed of course.)

The patch needs an #ifdef SOUP_TYPE_CONTENT_DECODER because otherwise it fails with current releases.

We decided to not handle this, and assume people mostly know what they're doing when using development releases. 2.29.4 will have it.
