get_extension_funcs () is not supported

[alex-mashin]

Under HHVM 3.10 and 3.10.1 and probably under several previous versions an attemp to call get_extension_funcs ('(extension)') causes a fatal error:

Fatal error: f_get_extension_funcs is not supported: extensions are built differently in (path to file).php on line ...

This breaks at least one extension: luasandbox (see https://phabricator.wikimedia.org/T115779).

This is present for like always. You can track it down to HHVM 2.x. So this is not about an updated hhvm version, it's about code that changed in luasandbox I assume.

@sgolemon attached a TODO to the function

hhvm/hphp/runtime/ext/std/ext_std_options.cpp

Line 246 in a994278

static Array HHVM_FUNCTION(get_extension_funcs,

[alex-mashin]

So, there is a way to build luasanbox under HHVM 3.11 (and earlier versions, I suppose): just add some parametres to cmake . (see https://phabricator.wikimedia.org/T115779#1892540).

Whether this remains a bug than needs fixing, since there is still an incompability with PHP, I don't know.

This should be fairly easy to implement, just capture the functions as they get registered.
