Bug description:PHP temp files not deleted when also using a CGI script
Description:
------------
This bug is very specific to Windows. When executing a generic file upload
using PHP, if at anytime while the file is being uploaded Apache then runs
a CGI script like PERL or a C program, and the upload ends while the CGI
script is still running, the uploaded file(s) in the temp directory will
remain behind forever.
In order to avoid this the âphp_do_open_temporary_fileâ routine will
have to not use the âVCWD_OPEN_MODEâ routine to open the temp file. A
generic Windows âopenâ call allows child processes to inherit their
handles. The temp file would need to be opened with a âCreateFileâ
call to open the file and specify the pSecurityAttributes option with
bInheritHandle set to FALSE so that a child process will not inherit the
open file handle. The rub is this call uses a non-compatible handle so
everyone who uses this handle has to be modified as well.
Test script:
---------------
Write or use any simple PHP upload program. Next use CGI program below --
it doesn't need to do anything except take time. So start the PHP upload,
then start the CGI program below from a webpage. Make sure the PHP upload
completes before the script ends.
#include <windows.h>
void main(){
Sleep(2*60*1000); // sleep 2 minutes
}
Expected result:
----------------
The file should be uploaded and the temp file in the temp directory should
not be present when done. It should be moved to the destination directory.
Actual result:
--------------
The temp file remains forever in the temp directory, though the file is
copied correctly to the destination directory.
