Windows 2000 / IIS 5.0 / isapi ------------------------------------------------------------------------ [2003-01-02 05:44:19] thies@php.net OCI(in_call) is a thread-local variable. so it's only global the the current thread. ------------------------------------------------------------------------ [2002-12-23 07:59:47] vivanov at tmsoft-ltd dot kiev dot ua I have same problem with "OCI8 Recursive call". This error happens when PHP works as !ISAPI module! (not CGI) under IIS. I just analyzed source and think I found where bug is. In case of ISAPI module functions of this extension (and OCI8 calls) can be called _simultaneously_ (not recursive but parallel) from different threads. conclusion: following manner of using flag 'in_call' is erroneous: ---- ext/oci8.c ----- #define CALL_OCI(call) \ { \ if (OCI(in_call)) { \ php_error(E_WARNING, "OCI8 Recursive call!\n"); \ exit(-1); \ } else { \ OCI(in_call)=1; \ call; \ OCI(in_call)=0; \ } \ } #define CALL_OCI_RETURN(retcode,call) \ // ... similar code I propose two alternatives: 1) remove away this checks 2) use some synchonization mechanizm instead >as i don't use windows myself there's >nothing i can do to.... If need, I can provide help -- P.S. sorry about poor english... My native lang. is C/C++ ;) ------------------------------------------------------------------------ [2002-10-28 08:39:42] thies@php.net as i don't use windows myself there's nothing i can do to help you. maybe try to find someone on php-db who has this setup working. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
