             Summary: _TSPEC is not populated on de-serialization of type 
classes
                 Key: THRIFT-3874
                 URL: https://issues.apache.org/jira/browse/THRIFT-3874
             Project: Thrift
          Issue Type: Bug
          Components: PHP - Compiler
    Affects Versions: 0.9.3
            Reporter: Aleksandr Kavun


When type class which was serialized and deserialized by internal PHP functions 
(for example, if data was stored to memcache and then retrieved) is used in 
requests, thrift_extension gives an 'Attempt to send non-Thrift object as a 
T_STRUCT' error.

This is because thrift_extension binary_serialize() function is tries to access 
to the $_TSPEC static property of object to determine it's target structure. 
Static $_TSPEC array for generated PHP classes is populated in __construct(). 
But when objects are deserialized, __construct() isn't called, instead of that 
PHP calls __wakeup() function. So type class should be instantiated once before 
sending it via Thrift.

The solution is to move code that populates $_TSPEC out of constructor to the 
generic function, and call this function both in __construct() and __wakeup() 
functions.
