Re: cvs commit: httpd-2.0 STATUS

[Jean-Jacques Clar]

Loading a process in its own address space require that all of the modules that it has direct dependencies on, have also to be loaded in that same address space. This is an expensive process, especially when it comes to CGIs that are loaded to serve their content and then unloaded. A marshaling layer exist between the protected address space and the kernel to ensure that loaded applications cannot corrupt kernel memory. The performance hits of isolating a process is not negligible. Process running in OS address space are also easier to debug using our internal debugger then having the same process running in its own address space.   in two worlds: performance and usability >>> [EMAIL PROTECTED] 6/22/2004 8:34:54 PM >>> Uh, then may I follow up with another stupid, obvious question, if using another address space insulates the parent application and, in some cases, the server from a crash resulting from an unstable module, why do they all use the same address space on novell?  Does this compromise a security measure in the case of a module fail or crash?
