new/different problem in shutdown

zeev,andi i have a problem with the oci-extension - it makes heaviy usage of ref-counting and creates dependices between resouces using refcounts. so i depend on a defined shutdown order and i also depend on the complete symbol-table to be destroyed before zend_destroy_rsrc_list is called as zend_destroy_rsrc_list won't work with my dependicies. i have created a small testcase that shows my problem without using the oci extension: the problem is that if a function calles exit the argumets for that function are _not_ destroyed in the shutdown mechanism of zend - <? function any($fh) { // exit(); // exit in a function is noo good... } $fp = fopen("/tmp/1","r"); any($fp); ?> if i set a breakpoint in _file_fopen_dtor (whic is the dtor for all fopen calls) i get these call frames _not_ calling exit in any($fh); #0 _file_fopen_dtor (rsrc=0x8420554) at /home/thies/devel/php4/ext/standard/file.c:149 #1 0x08190cbb in list_entry_destructor (ptr=0x8420554) at ../../php4/Zend/zend_list.c:179 #2 0x0818e65d in zend_hash_del_key_or_index (ht=0x83ae410, arKey=0x0, nKeyLength=0, h=1, flag=1) at ../../php4/Zend/zend_hash.c:543 #3 0x08190a25 in zend_list_delete (id=1) at ../../php4/Zend/zend_list.c:57 #4 0x081a5d70 in _zval_dtor (zvalue=0x8420484, __zend_filename=0x830aa40 "../../php4/Zend/zend_execute_API.c", __zend_lineno=260) at ../../php4/Zend/zend_variables.c:80 #5 0x08193742 in _zval_ptr_dtor (zval_ptr=0x84205a0, __zend_filename=0x8316ce0 "../../php4/Zend/zend_variables.c", __zend_lineno=169) at ../../php4/Zend/zend_execute_API.c:260 #6 0x081a5fcb in _zval_ptr_dtor_wrapper (zval_ptr=0x84205a0) at ../../php4/Zend/zend_variables.c:169 #7 0x0818e789 in zend_hash_destroy (ht=0x83ae2ec) at ../../php4/Zend/zend_hash.c:572 #8 0x081934f2 in shutdown_executor () at ../../php4/Zend/zend_execute_API.c:164 #9 0x08195a70 in zend_deactivate () at ../../php4/Zend/zend.c:538 #10 0x08089af9 in php_request_shutdown (dummy=0x0) at /home/thies/devel/php4/main/main.c:692 #11 0x08085bd3 in main (argc=2, argv=0xbffff7a4) at /home/thies/devel/php4/sapi/cgi/cgi_main.c:790 #12 0x409e3450 in __libc_start_main () from /lib/libc.so.6 as you can see $fp is freed thru the call to zend_hash_destroy(&EG(symbol_table)); in shutdown_executor. but not so if i'm _calling_ exit in any($fh); #0 _file_fopen_dtor (rsrc=0x84205cc) at /home/thies/devel/php4/ext/standard/file.c:149 #1 0x08190cbb in list_entry_destructor (ptr=0x84205cc) at ../../php4/Zend/zend_list.c:179 #2 0x0818ea00 in zend_hash_apply_deleter (ht=0x83ae410, p=0x8420574) at ../../php4/Zend/zend_hash.c:627 #3 0x0818ebae in zend_hash_graceful_destroy (ht=0x83ae410) at ../../php4/Zend/zend_hash.c:678 #4 0x08190e13 in zend_destroy_rsrc_list () at ../../php4/Zend/zend_list.c:234 #5 0x08193591 in shutdown_executor () at ../../php4/Zend/zend_execute_API.c:178 #6 0x08195a70 in zend_deactivate () at ../../php4/Zend/zend.c:538 #7 0x08089af9 in php_request_shutdown (dummy=0x0) at /home/thies/devel/php4/main/main.c:692 #8 0x08085bd3 in main (argc=2, argv=0xbffff7a4) at /home/thies/devel/php4/sapi/cgi/cgi_main.c:790 #9 0x409e3450 in __libc_start_main () from /lib/libc.so.6 (gdb) r as you see the resource is cleaned thru zend_destroy_rsrc_list which won't work with dependicies. again the problem is that the arguments on the stack do _not_ get cleared if a function calls exit(). what can be done? tc
