Store leaks as a new class that has a pretty descriptor and breaks out the leak information for easy inspection. Use a stable sort on leaks, sort the biggest leak to the front of the Array. Make whyAlive describe the top leaks. LzDebug.*: Use user toString methods, obey unique flag. LzFormatter: New formatting flag `=` takes the next argument as the object to be represented by the format (overriding the normal hot-linking that occurs in the debugger so you can write a custom representation for an object).

Summary: Make the memory tracer generic
New Features: Memory tracing now works (for some definition of works)
in DHTML in addition to SWF.
Bugs Fixed:
LPP-2071: '__LzDebug.whyAlive() incorrectly reports leaking arrays with SWF8'Technical Reviewer: a.bargull@intensis.de (pending)
QA Reviewer: promanik@laszlosystems.com (message://<20071216160543.EBA091EF912@hemicuda.laszlosystems.com>)
Documentation:
Debug.markObjects, findNewObjects, whyAlive now work in SWF and
DHTML. DHTML is only beta-quality, and you will get a warning
saying so, because it appears that some underlying runtimes
themselves leak DOM objects (or our usage of them causes them to
be leaked). It works reasonably well in Safari, less well in
Firefox, hangs Opera, is untested in IE (but IE has its own leak
tools).
Details:
kernel.js: Initialize the debug window early so memory tracing can
find it. Use a static style for debugger output, so that a new
CSSStyle object is not consed for every line of debugger output.
LzMemory.lzs: Make this generic (although there are still some if
($as2) bits for now, I think a unified code base is better than
splitting this into the kernels). Add some metering to see how
the background tracer is working. Add some documentation. Add
some try/catch blocks to ignore errors trying to trace native
wrapped objects in DHTML. Don't trace native wrapped object slots
that return a 'new' object each time you access them. Use
set/clearInterval instead of the old tracer movieclip to run the
background task. Fix the path evaluator to be correct and
platform-neutral. Use objectOwnProperties to find slots to trace.
Make the code to hide the debugger from the leak detector generic,
hide the debugger DOM tree. Make whyAlive output all relevant
data, so it can be invoked as a button, not just from the
debugger.
Library.lzs: switch from the platform leak detector to the generic
one.
LzRuntime: Use static style for debugger output.
laszlo-debugger.css: Define that static style.
Tests:
The following test program works for me (pressing the 3 buttons at
the appropriate times, creates a leak report):
<canvas debug="true">
<simplelayout axis="x" />
<button onclick="Debug.markObjects()">Mark</button>
<button onclick="Debug.findNewObjects()">Find New</button>
<button onclick="Debug.whyAlive()">Why Alive</button>
</canvas>
