PHP 4.0 Bug #4576: script output stops after session_start()

From: olivier.sessink@guest.pk.wau.nl Operating system: win NT 4.00.1381, IIS 4.0 PHP version: 4.0.0 Release PHP Bug Type: Session related Bug description: script output stops after session_start() Using the ISAPI module (php 4.0.0) we can't get sessions working. The php4 on Debian Linux is 100% stable but the win32 version seems to be still buggy. First a documentation problem: the errorlog reported it couldn't save the session files. It turns out the session path needs to be on the same drive as the documentroot. ( c:\tmp\ as session save path doesn't work when the documentroot is on f:, only after creating f:\tmp\ we saw session files created). The config file reads (the c:\ is the session.save_path is NOT USED, it places the files in f:\tmp2\ !!!!!): [Session] session.save_handler = files ;handler used to store/retrieve data session.save_path = c:\tmp2\ ; argument passed to save_handler ; in the case of files, this is the ; path where data files are stored session.use_cookies = 1 ; whether to use cookies session.name = PHPSESSID ; name of the session ; is used as cookie name session.auto_start = 0 ; initialize session on request startup session.cookie_lifetime = 0 ; lifetime in seconds of cookie ; or if 0, until browser is restarted session.cookie_path = / ; the path the cookie is valid for session.cookie_domain = fbt.eitn.wau.nl ; the domain the cookie is valid for session.serialize_handler = php ; handler used to serialize data ; php is the standard serializer of PHP session.gc_probability = 1 ; percentual probability that the ; 'garbage collection' process is started ; on every session initialization session.gc_maxlifetime = 1440 ; after this number of seconds, stored ; data will be seen as 'garbage' and ; cleaned up by the gc process session.referer_check = 0 ; check HTTP Referer to invalidate ; externally stored URLs containing ids session.entropy_length = 0 ; how many bytes to read from the file session.entropy_file = ; specified here to create the session id ; session.entropy_length = 16 ; session.entropy_file = /dev/urandom session.cache_limiter = nocache ; set to {nocache,private,public} to ; determine HTTP caching aspects session.cache_expire = 180 ; document expires after n minutes But all output after session_start() is gone (the cookie is send, but that's about it), and session files are created but are empty. The eventlog shows: The HTTP server encountered an unhandled exception while processing the ISAPI Application ' php4isapi!HttpExtensionProc + 0x394 wam!SE_TABLE::ReleaseExtension(class HSE_BASE *) + 0x526 wam!SE_TABLE::ReleaseExtension(class HSE_BASE *) + 0x1313 wam!SE_TABLE::ReleaseExtension(class HSE_BASE *) + 0x11A8 w3svc!IIS_SERVER_INSTANCE::QueryServerSize(void)const + 0xC8 w3svc!PARAM_LIST::CanonList(void) + 0x2BE8 w3svc!HTTP_REQ_BASE::BuildURLMovedResponse(class BUFFER *,class STR *,unsigned long,int) + 0x377E w3svc!HTTP_REQ_BASE::BuildURLMovedResponse(class BUFFER *,class STR *,unsigned long,int) + 0x36EE w3svc!HTTP_REQ_BASE::TestConnection(void) + 0xA42 w3svc!ScanForTerminator(char const *) + 0x386 w3svc!HTTP_REQ_BASE::CheckForBasicAuthenticationHeader(char *) + 0x30FC w3svc!HTTP_REQ_BASE::CheckForBasicAuthenticationHeader(char *) + 0x3094 ISATQ!_AtqPostCompletionStatus@8 + 0x645 ISATQ!_AtqPostCompletionStatus@8 + 0x862 KERNEL32!lstrcmpiW + 0xBE '. Changing the handler to 'mm' didn't work as well, we didn't even got a cookie anymore. Using the php.exe also doesn't work. It does work in a dos box, but using a handler for .php4 being 'c:\php\php.exe %s %s' it returns no output and finally causes a timeout error on the server. Is the '%s %s' still needed? any help is very much appreciated bye, Olivier Sessink
