    Misc stuff

    nspluginviewer

    • Debug recent regressions
    • FP flash 10 workaround
    • Fix exitting on host exit, double-check some more

    to make sure no process leaks

    KJS and KJS/Frostbyte

    • Value for global code, used in domts at least
      • Regression SunSpider?
      • Performance eval?
    • return-within-finally
      • Needs testing.
    • Debugger, again
      • Mostly works, but stepping through ifs is funny --- need to figure out why
    • Unbreak CPU guard.
    • 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.
    • 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.
    • Easy one: custom StringImp::toString that takes care of object and prototype checking, etc. to avoid the extra lookup.
    • 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.
    • Solaris stack support for ade
    • Check bug #108538
    • 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

    • Do floating-point font size computation
    • 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.
