- Fix most of bug 13163 (see TODO for rest). This entails adding a version-string argument to nsIScriptContext::EvaluateString and passing it around lots of places in content sinks.
- Fix leaks and confusion about mSecurityManager and mNameSpaceManager in nsJSEnvironment.cpp. These still need to move from nsJSContext to nsGlobalWindow or thereabouts, jband and vidur are looking at that.
- Added comments and expanded tabs in nsJSEnvironment.cpp, esp. to EvaluateString. Also changed various nsresult vars to be named rv. Also restored brace/style conformity to nsJSProtocolHandler.cpp.
- Factored CompileFunction from AddScriptEventListener to pave the way for brutal sharing of compiled JS event handlers via JS_CloneFunctionObject.
- Lots of nsCOMPtr uses added. I'm using one for mNameSpaceManager. Hold mSecurityManager as a service explicitly, on the other hand (awaiting scc's fix to allow comptrs for services), and release in nsJSContext's dtor (fixing a leak). These two managers should be moved to the window object -- TODO item below.
- Hold JSRuntimeService along with JSRuntime for live of nsJSEnvironment, fix for shaver.
- Fix window.setTimeout etc. so the filename and line number of the timeout expr is propagated. This meant factoring nsJSUtils.cpp code.
- Fix all content sinks to use the same, and up-to-date JavaScript version parsing (whether for script type or for old language attribute); also fix SplitMimeType clones to strip whitespace.
- With waterson, fix bug in brutal-sharing version of XUL content sink: script src= should not evaluate the inline content of its tag.
