ECMA-357 botch where * or @b or (given valid namespace reference n) n::id
results in undefined, instead of a TypeError.
- Lazily bootstrap AnyName and AttributeName classes, instead of leaving the
former uninitialized, and initializing the latter only if QName is init'ed.
These classes, representing ECMA-357 internal types, must be initialized
in order to string conversion and default value on them to return useful
results. So this change also requires the shared qname_toString to cope
with these classes, which ape QName in having a JSXMLQName as private data.
- Revise Filtering Predicate Expressions bytecode schema to avoid bogo-script
creating in js_FilterXMLObject. With a new JSOP_ENDFILTER bytecode acting
in lieu of JSOP_POPV, but also exiting the nested js_Interpret() call, the
runtime can avoid trying to fake a JSScript for the subsequence of script
bytecode in parens in x.(e), that contains the bytecode for e plus the pop
or endfilter op.
This requires a historic reparameterization of js_Interpret to take the
starting pc! I cleaned up order of declaration, use, and useless init nits
for a few variables while messing with it.
- Based on the above change, fix the decompiler to handle filtered predicate
expressions -- that code was stubbed out till now, and I forgot to go back.
All better now, especially thanks to JSOP_ENDFILTER.
- Also while fixing filtered predicates, eliminate the useless TOK_RP parse
node above the parenthesized expression, to avoid a JSOP_GROUP bytecode.
- Fix js_GetAttributeNameObject so it doesn't take over its QName parameter's
object and rebind it to an object of class AttributeName -- instead, clone
the qn if necessary. This is important to cope with the errata, noticed a
while ago but finally recorded:
9.2.1.2 Step 2(e)(i, ii),
9.2.1.2 Step 7(e)(i),
9.2.1.3 Step 2(b)(ii)(1)(a)
All uses of a.[[Name]] for an attribute a in these sections that pass
that QName object to [[Delete]] must pass an AttributeName cloned from
a.[[Name]]. The [[Name]] internal property is always a QName instance
and never an AttributeName or AnyName instance. But [[Delete]] will
not operate on x.[[Attributes]] when given a QName by these sections,
so a child could be wrongly deleted instead of the attribute of the
same name.
This rework exposed a bug in the XML.prototype.name() impl, where it was
returning an AttributeName, not a QName, for attribute-class XML objects.
Clearly wrong -- the E4X spec makes plain early on that [[Name]] is always
a QName -- but the spec and e4x testsuite seemed to require it due to the
above-noted errata.

- Also fix longstanding bug where global regexps in precompiled scripts were
wrongly shared among threads/contexts (165201, r=shaver).
- Also fix strict-aliasing gcc warning causes (206599, r=bryner).

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.
