Hi everyone! I ventured into writing my first PHP extension and did pretty well so far following the existing documentation and example code inside the php source.
However, I hit an odd bug in my code that I can't quite explain. I'm obviously missing something and I hope someone here can point me in the right direction :) I'd like to set up a request global hashtable. For now I'm running ALLOC_HASHTABLE() and zend_hash_init() inside PHP_GINIT_FUNCTION. I then have a user function that's supposed to add entries to that hashtable and another user function that reads entries from the hashtable. I tested with code passed directly on the command line (using php -r) and that works just like I would expect it too. The value gets written to the hashtable and I can read it afterwards from the other function. I also verified it's the same value that I first stored, so from what I can tell the basic functionality is good. When I take the same testcode and write it into a file, and then run php on that file, execution aborts trying to allocate almost 2GB of memory when trying to store the value in the hashtable (using zend_hash_update()). I can see PHP_GINIT_FUNCTION being executed in that case as well so I'd assume the hashtable is setup just fine. Yet something is different. What's the difference between " php -r '' " and "php test.php" in that regard? I uploaded my current state of the extension to github in case someone would like to take a closer look at the code: https://github.com/pprkut/autoload-psr Thanks in advance! Grs, Heinz
