- Add JS1.5 getter/setter support in all its glory:
* getter function SN() {return ++x} at top-level or as a closure binds an SN
property getter than returns the incremented value of x. Likewise for
setter function SN(y) {return y = x}.
* getters and setters may be defined in an object literal:
o = {p getter:function() {return ++this.x},
p setter:function(y){return this.x = y},
x:42};
* getter= and setter= operators (compound tokens) may be used to bind getter
and setter properties dynamically:
o = new Object;
o.p getter= function() {return ++this.x};
o.p setter= function(y){return this.x = y};
o.x = 42;
Waldemar is concerned that this form will collide semantically with JS2, so
I am not committing to keeping it in JS1.5. I'd like to check my code in
ASAP so shaver can use it, and I'd also like to see this form get used (or
not) during Mozilla betas. Caveat emptor, and if you find this "dynamic"
or "imperative" form necessary and hard to substitute, please let me know.
If this proves important to users, then I think JS1.5 should keep it.
- Cleaned up property flags (in a binary-incompatible fashion -- who cares?) by
eliminating JSPROP_ASSIGNHACK and JSPROP_TINYIDHACK.
- Added JS_DONT_PRETTY_PRINT flag to be ORed with the indent argument to the
several JS_Decompile*() API calls. This avoids any newlines or identation in
the decompiled string.
- Improved and extended (for getter/setter non-reservation) scanner lookahead
by using a circular (power-of-2 sized) token buffer.
- Fix ECMA Edition 3 deviation where function f(){function g(){}} bound f.g by
mistake (it should arrange to make a closure named g in activations of f, but
it should not bind a property of function f).

- js_DecompileValueGenerator had rusted due to bytecode/source-note changes,
or maybe parts of it never worked right. Anyway, it now does not induce a
crashing underflow in the decompiler. As part of this fix, it now takes a
checkStack flag telling whether to look for the jsval v argument on the JS
stack. The calls from ImportProperty, js_SetProperty, and js_DeleteProperty
pass in v a jsval for the property id, which should not be sought after on
the stack (it might happen to be there due to o['p'] = 2, but we want to
decompile o["p"], not "p").
- js_DecompileValueGenerator would load a generating pc even if the value v
did not match the pc's corresponding stack item! Oops. This lead to less
than idea diagnostics.
- js_DecompileValueGenerator was also not mapping JSOP_TRAP to the real op at
a sufficiently early and univeral point in its control flow.
- Fix PopOff to assert and check for stack underflow in the decompiler, and
beef up PushOff too (it asserted, but did not check).
- js_ReportIsNotFunction now avoids JS_InternString by indexing directly into
cx->runtime->atomState.typeAtoms with the result of JS_TypeOfValue.
- Removed unnecessary local GC root reserved by non-zero trailing member of
obj_eval's JSFunctionSpec initializer.

to define an unbound global variable used to enumerate an empty object, when
the standard says no variable should be defined.
- Clean up minor nits, make comment style match prevailing, tighten up for..in
element-indexing special case comments.
- Fix js_Invoke to take CONSTRUCT and INTERNAL flags arg instead of a construct
boolean arg and the JSStackFrame internalCall mis-located boolean non-arg.
Use these flags correctly in all calls (previous version failed to set the
bogus frame.internalCall around js_Invoke calls from jsfun.c and jsstr.c).

+ elimination of most dependencies on NSPR
+ JS1.4 feature additions and accumulated bug fixes
More details are in last week's mozilla status report.

and development branches, including but
not limited to:
- 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.
