don't allow gc's during script hooks if CAUTIOUS_SCRIPTHOOK is defined (which it is, by default.) Should help with stability until we can fix the real problems.
Use JSVAL_ macros instead of JSD_* calls in jsdValue::GetJSType method, avoiding two c++ frames per call.
move debug object counters and various constructors to jsd_xpc.cpp
add LiveEphemeral struct to reperesent a link in a PRCList of ephemeral objects.
declare jsdIEphemeral interface in objects that need it, add invalidaAll static method to jsdIProperty and jsdIValue. jsdIObject still needs work.
Large changes to improve the way we deal with our wrappers around js engine structures. jsdIScript, jsdIStackFrame, jsdIValue, and jsdIProperty interfaces now inherit from a new interface "jsdIEphemeral". This interface is used to invalidate the wrapper. Once the wrapper is invalidated, *most* methods throw NS_ERROR_NOT_AVAILABLE, some interfaces, such as jsdIScript, cache important information so that the wrapper isn't utterly useless once it has been invalidated. The boolean isValid attribute can be used to see if the wrapper is still valid.
factor debug object counters into some simple macros
add new velid assertion macros for the new ephemeral objects
add utility functions for dealing with PR_CLISTs full of ephemeral objects.
invalidate the jsdIFrame after the execution hook completes
move some c/dtors from jsd_xpc.h over here to avoid exposing debug object counters, and repeating some macros
fix incorrectly set out parameter in getValue::GetDoubleValue
declare and initialize new provate members in jsdScript, copy important script properties at jsdScript creation time, so they're around after Invalidate().
large changes to fix the following bugs:
82684, crash manually clearing breakpoint
*actually* clearing mValid in jsdScript::Invalidate fixed this one.
85636, assertions on quiting venkman
jsdService::Off now disconnects the hooks into JSD, to avoid calling back into js after that. It also processes any pending script delete events that occurred during the last GC. The code to process the gPendingScripts list has been factored out of the gc callback. Processing the dead script list allows us to properly finalize all of the jsdIScript object, which seems to clear up the "gc roots exist at shutdown" assertions. In effect, these changes get rid of *all* of the jsd related assertions on exit.
Added isOn attribute to jsdIService.
Added isValid attribute to jsdIScript. We now prefetch appropriate properties from the underlying JSDScript, so that it's available after the script is Invalidate()d
moved jsdService constructor to jsd_xpc.h
Save the runtime passed to OnForRuntime so we can use it to clear the GC Gallback in Off().
add onForRuntime() method to jsdIDebuggerService to let native code turn on the deubgger (on() can only be called from js)
register an app-start observer so we can turn on the debugger at startup if "js.debugger.autostart" pref is true.
r=peterv, bug 81840
remove jsdIContext and jsdIThreadstate interfaces
add TYPE_BOOLEAN to jsdIValue
update callback signatures to reflect the removal of jsdIContext and jsdIThreadstate
add errorHook and throwHook attributes to jsdIDebuggerService
remove jsdThreadState and jsdContext objects.
consolidate ExecutionHook and BreakpointHook callbacks
remove return value checking from all methods (xpconnect does this for us.)
