I was learning from @jdelong and he said that you should use
double quotes for local includes and angle brackets for library
includes. I asked why our code was the way it was, and he said he wanted
to clean it up. I beat him to it :)
Conflicts:
hphp/runtime/base/server/admin_request_handler.cpp
hphp/runtime/vm/named_entity.h
Make the targetcache the one true home for constants,
so we dont need to (also) insert them all into
VMExecutionContext::m_constants (which is now gone).
By also making "non-volatile" constants persistent, we save
initializing most of them at all in RepoAuthoritative mode.
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*.
We only used it to get the values of certain class constants,
and to define the ObjectStaticCallbacks for every class.
We can put the class constants directly into the class_map
(we should have done that before for perf reasons), and then
the only remaining use of ObjectStaticCallbacks is to proxy
the Class* for each builtin class. So just use the Class*
directly.
Once this is in, Im just a small step away from eliminating
make -C hphp/system - so Im leaving a lot of dead code here.
Its going to be easier to delete it en masse, rather than
try to pick and chose now.
It was only used to fold SimpleFunctionCall nodes. Ive setup enough
of the runtime that we can call invoke (which goes through hhvm's
normal Func dispatch), and then removed it.
This basically targetted symbols.php, and Globals, but ended up
killing a lot more. I could keep adding more and more, but
this seems like a good point to stop and continue with
another diff.
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.
