to the JS API, for per class extra slots beyond JSSLOT_PRIVATE (or starting
there for a class that lacks JSCLASS_HAS_PRIVATE). To avoid penalizing all
instances, these slots are allocated only upon first property-owned slot
allocation, or upon first JS_SetReservedSlot.
This entailed adding getRequiredSlot and setRequiredSlot hooks to the
JSObjectOps struct, and making obj->slots self-describing, a la BSTR. It
also afforded me a chance to clean up obj->slots locking so that non-native
JSObjectOps didn't risk unlocked accesses! Now there are thread-safe hooks
for all uses of obj.
First consumer is the new, DOM-glue-unifying XPConnect, which needs two
slots per wrapped function. Hence the change to js_FunctionClass.flags'
initializer.
- Commented the heck out of JSClass and JSObjectOps function typedefs in
jspubtd.h. I hope embedders see these comments!
- Fix JS_XDRValue's default case to handle int exclusively, there is no other
possible type (and therefore no JSMSG_BAD_JVAL_TYPE error).
- Clean up tabs in select old, tab-ridden files and sections.
- s/\<fh\>/file/g for stdio FILE * canonical variable names.

- Optimize integer ++ and -- to avoid double-to-int, which is quite costly for
some compilers (ftol on Windows with MSVC).
- Optimized arguments[i] and arguments.length references to use bytecodes that
avoid creating an arguments object for the current frame. This entailed
simplifying the compiler to avoid flagging functions and scripts that set
arguments, since we have code in jsfun.c to catch such sets at runtime.
- The code generator now eliminates useless expression statements, giving a
strict warning about them.
- Rationalized jsemit.c's LookupArgOrVar to have well-defined results in *pn.
Eliminate bytecode specializations for argument and local variable gets and
sets from jsparse.c -- these precede jsemit.c's LookupArgOrVar and frustrate
it, by setting pn_slot non-negative too early.
- Code generation errors set report->filename and report->lineno, rather than
hacking "{0}, line {1}: " into the localized message.
- Bogus JSFRAME_VAROBJBUG removed, JSOPTION_VAROBJFIX is sufficient.
- Spruce up jsinterp.c macros to use JS_BEGIN/END_MACRO brackets if possible.
- Avoid calling JS_PropertyStub. The call is too costly compared to a branch
in the caller.

ECMA-262 octal literals. Old code would split 08 into 0 and 8 if JS1.2 or
other non-ECMA version, and always split 078 into 07 and 8, resulting in
missing ; syntax errors.
- Fix CheckFinalReturn to be aware of JS_HAS_EXCEPTIONS, finally (sic). Lots
of help from jag (Peter Annema, disttsc@bart.nl), thank him.
Both changes got lumped under bug 49233, and are r=jband, sr=shaver.

code review and fixes (r=chouck@geocast.com). He needs this cuz he has no
knowledge of exact number of properties before new-style enumerating them.
- Patch up jsdbgapi.c a bit -- it needs to use OBJ_GET_ATTRIBUTES and new APIs
to do a better job describing properties to a debugger.
- Add JSMSG_CANT_DESCRIBE_PROPS for bogus non-native error case in jsdbgapi.c.
- Fix "Inappropriate" => "invalid" in JSMSG_BAD_ARRAY_LENGTH message.

- 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).
