Hi all! I want to create a daemon process from within a python cgi script running on apache/win32. This daemon's lifetime is longer than that of the creating cgi script - of course, because the script starts the daemon, writes some html code to stdout and then exits. This simple task kept me busy for weeks!
What I'm doing in the script is to spawn a new process with win32process.CreateProcess() or subprocess.Popen() and then it writes html code which dynamically creates a web-page consisting of 3 frames. The frame references are pointing to the very same script which will then be executed by apache multiple times until all frames are rendered (this times bypassing the daemon creation code). The strange thing is that the script execution for rendering the last frame is delayed until the daemon process exits! I completely do not understand this. The daemon process starts and the script is executed repeatedly for all frame references but the last one, leaving the browser in a 'page loading' state. As soon as the daemon process exits, the script is executed again to generate the last frame and the page is loaded completely. When the script doesn't start the daemon, the frames are filled without any delay. Does anybody have an idea what goes wrong here? Is there any connection between a parent and a child process which has to be released before the processes can die independently? Are there any Apache-specific things to handle when spawning processes? Your help would be greatly appreciated!
