Issue with op_array moving

Hi all, I am writing an extension that does performance monitoring. I guess somewhat like xdebug but a bit different. The user can specify the functions / methods they care about and I will time the execution of those things. I do this by hooking zend_execute. My hook is: void rrdmon_execute (zend_op_array *op_array TSRMLS_DC) { ... } After a php file has loaded ((op_array->function_name == NULL) && op_array->filename)) I check through the list of functions the user wants to monitor. I check to see if the thing they want to hook is a class or a normal function and then do something like this: HashTable *ftbl = EG(function_table); zend_function *func; if (is_a_class_method) { zend_class_entry **ce; if (zend_hash_find (CG(class_table), classnm, classnmlen, (void **)&ce) == FAILURE) {

    return;

} ftbl = &((*ce)->function_table); } if (zend_hash_find (ftbl, funcnm, funcnmlen, (void **)&func) == FAILURE) { return; } func->op_array.reserved[0] = pointer_to_my_stuff; I dont actually use reserved[0] I do it properly getting the next offset but this was for illustrative purposes only. Then in my rrdmon_execute I do something like: if (op_array->reserved[0]) { ... do stuff ...; } This all works well, until I tried this with a class that had a namespace. The method is Symfony\Component\HttpKernel\Controller\ControllerResolver::getController. It finds the class name (everything pre the ::) in CG(class_table) and it finds the function (getController) in that class's function table, but unlike every other class and function I have tested this with, the op_array that I put my stuff into isn't the one being executed. That is, func->op_array isn't the op_array that ends up getting passed to rrdmon_execute(). This seems to only be an issue with namespaces. Symfony does a bunch of weird caching stuff so the class gets loaded out of a cache file but at this level, that shouldn't matter. So please, can someone who knows Zend's guts a bit better tell me if I am doing something wrong (this has worked just fine for several months up until I decided to time that stuff in Symfony which is the first time I have encountered namespaces) or if the op_array somehow gets moved around or how I should deal with namespaces for these purposes? Any help greatly appreciated. --Jim Edmunds.
