First of all, there is very poor documentation about this subject on the web. Even the Zend-docs are outdated. This doesn't make it easier. But anyway, I have a real problem, which I can't fix... I hope one of you know what to do about it:
most of the code works, it loads a script, runs it, and it stops when I want it to. Now I want to register functions on the fly. This is the part where it goes wrong.
I run a:
zend_register_functions(NULL, add_func_array, CG(function_table), MODULE_PERSISTENT);
two times, some cycles after the zend_execute_file is called (more exact: it is done on user-request), every time with an other function-name. Now I can call both functions from PHP, that works. But now when I close my application, it crashes. Glibc gives me an error that a pointer is tried to free'd twice. Here the GDB output:
#0 0x0000002a95e009b9 in raise () from /lib/tls/libc.so.6 #1 0x0000002a95e01fff in abort () from /lib/tls/libc.so.6 #2 0x0000002a95e3be7b in mallopt () from /lib/tls/libc.so.6 #3 0x0000002a95e39a22 in free () from /lib/tls/libc.so.6 #4 0x0000002a9760d1c0 in _efree () from /usr/lib/libphp5.so #5 0x0000002a97619e36 in destroy_op_array () from /usr/lib/libphp5.so #6 0x0000002a97619beb in destroy_zend_function () from /usr/lib/libphp5.so #7 0x0000002a97619bf9 in zend_function_dtor () from /usr/lib/libphp5.so #8 0x0000002a97627c2f in zend_hash_destroy () from /usr/lib/libphp5.so #9 0x0000002a97620be3 in zend_shutdown () from /usr/lib/libphp5.s
I tried almost everything, and I am running out of ideas.. is this a bug, or is it not allowed to add functions on the fly to the same hash-table, or...
Of course I tried many many scenarios to isolate the problem. It works all pretty and nice, as long as I register all the functions BEFORE running zend_execute_file. I want to add functions after that time. Nowhere in the source I can see such restriction, and I see no reason why it should not work.. I hope you guys can help me.
Oh, one more note: I am running 64-bit linux, maybe that has something to do with it..
Tnx for your time,
