This is a partial step towards merging the HPHP::VM namespace
up into its parent. To keep it reviewable/mergeable I'm not doing
everything at once here, but most of the code I've touched seems
improved. I've drawn an invisible line around the jit, Unit and
its cohort (Class, Func, PreClass, etc.); we'll get back to them
soon.
Grepping around for string literals passed to o_invoke turned up these suspects. It's not a great practice. The only one that might matter to perf is the "count" invocation in ext_array.
unserialize() and call_user_func_array() were straightforward. They were
called from all over the runtime, but I renamed those implementations
and codemodded the runtime.
The is_* functions were only ever being called by the CVarRef signature,
so I deleted all the other ones (same for f_gettype). Only some of the
is_* functions were being called from the runtime, so I made inline
versions of those without the f_ prefix.
Post-hphpc, declaring builtins as inline is useless, which obviates the
need for this layer.
This doesn't fully delete the file, because I wanted to keep mindless
parts and use-your-brain parts separate. This is the mindless part. The
remaining functions in noinline.cpp are no-inline wrappers around
(a) a function that isn't defined in an extension, call_user_func_array,
and (b) calling polymorphic is_* functions, which can probably mostly go
away now. But I wanted to exercise more care around those, so they'll
come in a followup diff.
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.
