    Current priorities

    • Look at selection crash affecting Kopete (bug #170749
    • Reply to the French Windows-using testcase-providing gentleman
    • Fix uga's image bug
    • Move blur/focus to Element.
    • onchange change
    • head/body parsing
    • Finish up/cleanup reindenting stuff in the debugger.
    • Fix namespacing of WTF
    • Backport the comment lexing fix
      • Now it's there, look at google groups again --- that bit is out of the way
      • Something is funny w/it and CSS?
    • Do the nspluginviewer exit fix
    • Finish up the FrameArray removal, as below and also for the crasher
    • Make a lot less stuff ReadOnly.
    • Disabled color for Roman
    • Accel handling?
    • Pick up the getComputedStyle stuff from WC
    • the adblock stuff is in progress, but probably should be trunk-only.
    • I also had mem-use reduction change for KJS, which had the issue of

    the global code's lack of body for rewinding. Do we ever run code in GlobalExec, though? We shouldn't...

    • There was also array iteration stuff, not sure it matters, though
    • favicon fix for Acid3 --- ask dfaure
      • Also look at history/:visited, combined with vtokarev's stuff.
    • Disabled focus stuff: bug #159682
    • Finish up the parsing fix in bug #169556 --- talk to maelcum
    • Wrap up the background-position parsing stuff
      • Needs further fix for , parsing
    • Figure out the selector crash Frank R. testcased, too.
    • Fix const stuff
    • The color inheritance stuff... Also, makes me wonder about currentColor --- that's tied in to gcs, though.
      • Spart fixed that and added currentColor parsing in trunk. So with GCS I should be able to add it to canvas.
    • KMail drag icon: http://lxr.kde.org/source/KDE/kdepim/kmail/kmheaders.cpp#2419
    • Look at the Ebay thing
    • TinyMCE online demo page error.
    • Something is wrong with abcnews.com

    Misc stuff

    nspluginviewer

    • Debug recent regressions... if I could reproduce it
    • Try to catch Seli about the SuSE/GlibEvents path. Or sic the reporters on the SuSE bugzilla.

    Canvas

    • Update for createImageData, range changes
    • Update error handling?
    • setFillColor(double r, double g, double b, double a) extension
    • Can now make width/height reflecting, with ::rewriteValue

    KJS and KJS/Frostbyte

    • Idea: split off the hash table stuff off from JSObject
      • Probably not workable since the prototype even of pure objects can have hashtable properties. Object.prototype doesn't, however, so we can bypass a lot of stuff. Properties there can only be DontEnum or default, too.
    • Try to do inline-in-ExecState scopeChainNodes again --- but can they be torn off?
      • May be store in the action? Seems illegal type-wise.
    • Debugger, again
      • Mostly works, but stepping through ifs is funny --- need to figure out why
    • Unbreak CPU guard.
    • See if we can keep track of the current function body in the parser. Use that to help track of things like presence of "arguments"
      • With this and eval operator, may be able to get rid of an explicit activation and scope chain entry...
    • Type system changes:
      • Make int32 immediates apply to int32 values --- add a notion of exact embedding
      • Add a notion of value/number dual-use in registers --- use DontMark bit to distinguish which it is
    • Idea: have a template for activation in FunctionImp, and then just memcpy, minus the params, on startup
      • still need to setup functions separately, though.
      • seems slower, actually
    • Idea, part 2: use the above to setup immediates in the same place as registers. This can simplify the IR a lot and shrink the loop considerably. Also means there is no longer architecture differences in 32-bit and 64-bit needs at the IR level, and the IR gets smaller.
      • Of course, recursion more expensive. But worth a try?
    • BUG: need to flush lazy local copies at function call (or do I do it already?)
    • Alternative/conflict with below: if using a single stack for parameter passing/direct calls, we want to always do stack allocation and then do a deferred tearoff when needed --- this may actually be visible based on refcount of the scope chain, except when manually done.
      • That's actually done, but I am not sure of how to best combine it with other stuff
    • Do segmented/nonmoveable stack allocation --- just have a list of pieces, and work on them one at a time. Older ones can be recycled. This means we never have to refetch the locals array.Also avoids the WARNING WARNING WARNING part.
    • Do deferred tearoffs.
    • eval operator/eval tearoffs
      • tearoffs done.
      • With eval operator, if I keep track of lexical depth, may be able to directly route to global object, etc. Needs thought.
    • Fix const
    • obscure sequencing thing
      • seems like an another regression on the TC though --- exception precision?
    • merge in the API, etc., from trunk
    • Do the List performance changes
    • Do IR dialectes for 32- and 64-bit -- e.g. PointerCell
      • Also probably double-allocator for 32-bit.
    • Do a review pass over API to make sure not BC leaks.
    • Double-check global handling, synchronize with JSC
    • Consider using packed immediate/register bits. The key observation is that locals are read from an array, too, so we could do something like:
      arg0 = argsType[(fullOp >> 16) & 1][offsetVal];
    
    • Crazy idea: when going to proper CFG construction, do we even have to linearize?

    KHTML - Short-term stuff

    • Don't forget the clip:rect(auto, 123, ...) stuff
    • Don't forget the leak fixes
      • consult with Maciej and Micha
    • There was a change in getElementsByClassName case behavior
    • Do floating-point font size computation
      • Or rather e-mail it to kfm-devel
    • Fix the damn image-load-event-thing in iframes
    • Go through the canvas testcase again
    • Fix noscript on DOM ops. Should it just display:none? I guess I should check HTML5
    • Important, don't know how to fix: bug #163359
    • Need to debug various editors
    • bug #162745 -- for CSS, we need to strip whitespace from URLs. Ditto for object, I'd think. Perhaps completeURL should do it.
    • For objects, empty URLs should probably embed still -- but when? CompleteURL on empty seems like a culprit for the self-embed bugs.
    • Inherit params
    • bug #161196 --- option value --- should be super-quick
    • JS Redirects
    • Iframe stuff
    • Fix the paranoia affecting(?) flickr(?) upload bug #126974
    • The XHTML parser mode
    • Check the XML parser -- QXML workaround might not be needed, weird whitespace handling and recovery stuff
    • Check the implicit node stuff. Only the form one seems correct to me, and that can be done w/o wasting a bit at top-level.
    • the libthai thing
    • bug #104358
    • XHR:
    • bug #103250 --- KWallet and pages with textareas.

    khtmlImLoad

    • Allan's foreign loader patch
    • Scale animation provider for GIF --- bug #162614
    • Animation stoping
    • Better pre-blend cache?
    • FredrikH performance goodness?

    KHTML - Long term stuff

    Other long term stuff

    • Async loading of nspluginviewer somehow?

    Other kdelibs stuff

    • Figure out why the maxProcess stuff in kio_http doesn't seem to work.
