> _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.
