#41024 [Asn->Fbk]: FastCGI ISAPI DLL does not flush pipe handles on close

ID: 41024 Updated by: dmitry@php.net Reported By: barborak at basikgroup dot com -Status: Assigned +Status: Feedback Bug Type: CGI related Operating System: Windows XP Pro PHP Version: 6CVS-2007-04-08 (CVS) Assigned To: dmitry New Comment: How is it related to PHP? PHP team doesn't support this ISAPI module. Previous Comments: ------------------------------------------------------------------------ [2007-04-08 18:01:06] barborak at basikgroup dot com Description: ------------ Using the FastCGI ISAPI DLL with IIS 5 on Windows XP Professional to support dynamic servers written in Perl and using the FCGI Perl module works pretty well but there is an intermittent problem where the results are not completely written to the client. That is, a FastCGI request is handled correctly by the Perl program and a complete response is sent to the FastCGI ISAPI DLL (as I confirmed with a logging version of this DLL) but the complete response does not make it to the browser. I am no Windows guru, but I believe the problem is because the handle between the FastCGI ISAPI DLL and IIS is closed without first being flushed. By adding a call to FlushFileBuffers before the call to CloseHandle in OS_Close of fastcgi-isapi/libfcgi/os_win32.c, I no longer see this intermittent problem. If you are interested in this patch, I have posted it here: http://www.basikgroup.com/temp/fastcgi_isapi_flush_patch.txt Thanks, Mike ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41024&edit=1
