Fatal error when parsing shared library files

[bobbingwide]

The original logic in oikai_pseudo_reflect() would use Reflection function logic against the actual class, method or function if it was already loaded

We also tested if docblock comments were actually available. WP Engine's code stripped them.

When parsing an updated shared library file this logic led to a Fatal error due to differences between the actual file being parsed and the file that had been loaded. In our case the file we were parsing was libs/bobbfunc.php ( part of oik ) which is shared by oik-bwtrace. The version loaded by oik-bwtrace was older so the start and end line numbers for the functions were different.

Solution

In addition to testing if docblock comments are available, check if shared libraries have been loaded.
If they have then don't trust the code that's already been loaded. It may not match the code we want to parse.

This was mostly fixed by the changes to in b02269b with the function oikai_using_libs()
