word neologism, not two words.
- Use consistent neighboring terseness ("error" rather than "err" in intercaps
identifiers).
- Don't leave pointers in JSErrorReport to freed memory if bailing on OOM in
jscntxt.c:js_ExpandErrorArguments.
- Hanging indentation, code fusion via continue, and other misc. cleanups.
Fixed bug #317398, for loop without condition wasn't decompiling the body
correctly since the first statement in that body was getting eaten by
mistake when trying to consume the condition expression.
call, and experimented with copying the original JSErrorReport into
private data. Much of this to support a toString method for exception
objects.
It's not polished, but I wanted to get toString available quickly.
the compile-error reporting mechanism,
providing a way to associate exceptions
(very likely SyntaxError exceptions)
with compile-time errors.
(Hopefully this is temporary, as I'd
prefer one central place in the
error-reporting process to put the
js_ErrorToException call.)
Also changed the error reporter in js.c
to only ignore error reports marked with
the JSREPORT_EXCEPTION advisory flag when
the error occurs during javascript execution.
If it's at the toplevel compilation
level, then the error is still reported
(and the exception discarded.)
The api is feeling slightly dirtier, but
it still seems like the best
compromise...
enum JSErrNum, and changed a uintN
errorNumber declaration to JSErrNum.
It'd be nice to change the uintN
errorNumber field in JSErrorReport to
JSErrNum, but it's not clear that
JSErrNum is or should be exposed in the
API. Any C esthetes want to offer their
opinions?
It made my debugger slightly happier.

development branch:
- Preliminary exception handling per
ECMA proposal; try, multiple
catchblocks, and finally. Catchblocks
are of the form catch (v) or
catch(v:<guard>), where guard is an
optional boolean expression that is
evaluated to determine whether the
exception is to be caught by that block.
- ECMA-proposed 'in' operator; "'foo' in
o" or "4 in o" asks if o has property
foo or element 4.
- Added a new set of defines in
jsconfig.h for js 1.4
features-in-progress. (in, instanceof,
exception handling.) Default build
version is now 1.4. Fixed a few
conditional features that had become
broken.
- Progress towards porting to FreeBSD
and Alpha; casts of NaN and friends to
int are a little more localized. Not
there yet...
- New config files to compile on more
OSes; various fixes to improve
portability.

cast until after the double in question has been determined to be
finite, not NaN, etc. This may make the code a little more XP for
platforms like BSD and Alpha Linux that don't like casting strange

+ Changed the way JS wrapper functions for Java instance methods are constructed.
Previously, these were computed the first time that an instance method was
accessed for a particular JavaObject and cached in the native, private portion
of that JavaObject. However, the required call to JS_AddRoot() causes an root
to appear as a link in a cyclical graph, leading to uncollectible objects, i.e.
the JavaObject has a root pointer to the function object and the function has
a parent that points back to the JavaObject. Now, we compute the functions
at the time a class is reflected and use JS_CloneFunctionObject() each time
a JS wrapper function is needed, which is slower, but avoids this GC problem.
return the same Java object, both for efficiency and so that the '=='
operator works as expected in Java when comparing two JSObjects.
However, it is not possible to hold a reference to a Java object without
inhibiting GC of that object, at least not in a way that is portable
to all vendor's JVMs, i.e. a weak reference. So, for now, JSObject identity
is broken.
- Revise exception handling runtime info (now called trynotes a la srcnotes)
for more efficient loop control under JSOP_THROW. Avoid all uses of catch
and throw while at it, to make C++ lusers happy.
- Combine JSStackFrame.exception with rval, and rename
JSStackFrame.exceptPending to be ...throwing.
- Optimize JS_TypeOfValue a bit.
- Name, control flow, whitespace, etc. cleanup.
all element access expressions to strings, e.g. so that obj["3"] and
obj[3] refer to the same property for a JavaArray object.
= Return false when using 'delete' operator on JavaArray objects.
means that we had to switch from using NSPR hash tables to a private version.
The new jsj_hash.c file is derived from plhash.c, but it provides for an additional
argument to be passed to the hash key comparison function. This capability
is used to pass in the JNIEnv pointer.
On shutdown, LiveConnect now removes all references to Java objects and classes,
so that the JVM might be able to GC them.
command' hack - the resolver defined by js.c would get called to look
up 'assign' - and on Irix systems, it would find the 'assign' command
in the current path, and decide to define a function called 'assign'
in the global object that would run the assign command. Then when an
attempt was made to assign a property to the global object, the assign
command would get run, and unexpected behavior followed.
