Member Function Documentation

_deallocateUnusedMemory()

_deallocateUnusedMemory ( )

protected

Force to deallocate no longer used memory

Definition at line 58 of file MemoryUsageTest.php.

protected

Retrieve the allowed memory usage in bytes, depending on the environment

Returns

int

Definition at line 68 of file MemoryUsageTest.php.

    {
        // Memory usage limits should not be further increased, corresponding memory leaks have to be fixed instead!
        // @todo fix memory leak and decrease limit to 1 M (in scope of MAGETWO-47693 limit was temporary increased)
