http://issues.apache.org/bugzilla/show_bug.cgi?id=43534 Summary: mod_perl and FastCGI fails on Windows Product: Apache httpd-2 Version: 2.2.6 Platform: Other OS/Version: Windows 2000 Status: NEW Keywords: PatchAvailable Severity: normal Priority: P2 Component: Other Modules AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] The changes in APR 1.2.10+ and Apache 2.2.6 caused mod_perl 2.0.3 to fail on Windows. mod_perl attempts to save stdin and stdout on entry and restore them on exit. mod_perl uses POSIX-like int file descriptors - _fileno(stdin) and _fileno(stdout) - for this. These file descriptors are not updated by setting STD_INPUT_HANDLE and STD_OUTPUT_HANDLE via SetStdHandle(). For example, SetStdHandle(STD_INPUT_HANDLE, newhand) does not change the HANDLE associated with _fileno(stdin). _fileno(stdin) still refers to the original Windows HANDLE - the pipe handle, regardless of whether it is open or has been closed. This can be seen by comparing the return value from GetStdHandle(STD_INPUT_HANDLE) to the value from _get_osfhandle(_fileno(stdin)) before and after mpm_winnt.c replaces the stdin handle. mpm_winnt currently creates a HANDLE to "NUL" as a replacement stdout when Apache is run as a Windows Service. Because a console-device HANDLE is not useable (always returns "invalid handle") when it is inherited by a detached process, this is needed for command-line too. Attached is a patch to mpm_winnt (2.2.x branch) which: 1. Creates the "NUL" stdout in the parent for both service and cmd-line execution, rather than just for service. Only single-process mode (-X) retains the original console-device stdout HANDLE. 2. Uses _dup2() in the child to replace the stdin file descriptor with the stdout file descriptor (i.e. to set stdout to "NUL" except in single-process mode). Note that this has the side-effect of closing the regular Windows HANDLE to the stdin pipe too, so it must be done after the child is done reading from the parent. 3. Sets the Windows HANDLEs (but not the file descriptors) for stdout and stderr to INVALID_HANDLE_VALUE at child_init for FastCGI modules. See APR bug 43329. This would allow current Windows FastCGI modules to work with APR 1.2.10+ without requiring APR_NO_FILE flag changes until a major Apache release, while other non-Apache APR programs could still take advantage of the APR process creation changes. This patch works with mod_fastcgi, mod_fcgid, and mod_perl on Win2k and Vista when built with either VC6 and VS8. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
