Bug 24786 – WebKitDownload sometimes suggests peculiar filenames

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Christian Dywan]

WebKitDownload provides a "suggested filename". This works often enough but sometimes it suggests something like "jdk-6u13-windows-i586-p.exe&File=jdk-6u13-windows-i586-p.exe" which is obviously not ideal.
Another phenomenon seems to be URI encoded spaces, ie. %20, which is also not useful.

I think we should try to catch these cases.

Better handling of the URI that is to be downloaded to figure out a

name suggestion.

KURL has all we need =). We can even use the KURL the request itself holds in the future, when we have a proper WebKitNetworkRequest implementation committed =).

Looks good to me. Maybe you can briefly say in the changelog how is it better than before (no query, reference, escaping, etc).

Mmm, aren't you unrefing the network request twice now? Once in the request_download function, and once in the functions called that.

Xan's right, I'm not sure why I didn't get any crashers while testing, though I don't remember how/if I tested doing the actual downloads.

I guess you want to lose the g_debug. Looks good otherwise.
