They both returned the late static bound class, not the context
class. This meant that eg "constant('self::FOO')" was actually
returning what "constant('static::FOO')" should have done.
In addition, we often want the Class*, not its name, so
change them to return Class*. The remaining places that then
read the name from the Class* should be fixed to use the Class*
directly (in a later diff).
Finally, noticed that while "defined()" was recently fixed to
support "static::", "constant()" was not. Pulled out a common
function to find the correct Class*.
Replace "collection" with "collections" in various file names since
we typically use the plural form in conversation and documentation.
Add set() and removeAt() methods needed for collection interfaces. Also
add the KeyedIterable and KeyedIterator interfaces.
Add __construct() methods for collections
This diff eliminates setOpEqual() and appendOpEqual() from Variant, and
it also removes several methods from ObjectData: o_assign_op(), o_argval(),
setDummy(), init(), cloneDynamic(), o_setPublicWithRef(), o_i_set(),
getRedeclaredParent(), and o_propForIteration().
This diff also makes several methods in ObjectData non-virtual: destruct(),
o_toIterArray(), and o_getDynamicProperties(). To achieve this, some of the
logic from Instance was moved to ObjectData.
Finally, this diff gets rid of "hhvm/externals_stubs.cpp" and
"runtime/eval/eval.cpp".
This diff removes LVariableTable, RVariableTable, and getHphpBinaryType().
It also consolidates some of the include logic that was spread across
multiple files.
SharedMap was the last dependency on ZendArray. For its localCache,
use a TypedValue[] array indexed by SharedVariant.getIndex(), and
for escalate(mutableIteration), escalate to an HphpArray instead of
a ZendArray.
This diff suppresses the output of C++ for the "pure" classes defined in
system/classes, and it rips out all the uses of MethodCallPackage (except
for the i_* and ifa_* helpers, which we can go after separately).
Also cleans up a bunch of "if (hhvm)" and "#ifdef HHVM" checks in builtin_functions.cpp,
systemlib.cpp, object_data.cpp, and class_info.cpp (and the corresponding .h files).
Note that this does not completely remove the generated C++ files. We
still generate code for the PHP files in "system/globals" and we still
generate the g_class_map (because the VM needs g_class_map at startup
when it creates Class's for the extensions). We also still have the
dynamic_func_table/dynamic_class_table stuff, MethodCallPackage, and
the i_* and ifa_* helpers to support invoke_builtin() (which is still
used by the compiler).
This change is mostly for FB internal organizational reasons.
Building is not effected beyond the fact that the target now
lands in hphp/hhvm/hhvm rather than src/hhvm/hhvm.
