The is actually the behavior that we don't want on NetWare. Running CGI's or utilities like RotateLogs in a separate address space is very painful and requires overhead and a performance hit that we don't want. On NetWare we need to default to the current address space. BTW, an address space on NetWare is, for the most part, very different than on other platforms. 90% of what is running on the box, is running in the same address space. When we implemented the CGIMapExtension directive to associate a CGI extension with an executible (NetWare doesn't have a shell like BASH to handle the associations) there is an optional parameter called "detach" which allows the user to specify wheither the associated executible should be run in the current address space or a separate address space. The default is the current address space.

It's actually a major bump. Jeff eventually needs to backport the use of a different cmdtype for piped loggers in order to fix an outstanding PR and NetWare still needs to create piped logger processes as expected and recover from a historical lack of information provided to APR about whether or not the child process should run within the same address space of the parent. Surely there is some way to make this happen? What if the default in APR is to run in a separate address space*, and in places in Apache where on NetWare the child process should run in the same address space there is a call to the proper procattr manipulator to override the default so that the child runs in the same address space? (and ignore any APR_ENOTIMPL retcode from that procattr manipulator so that no ifdef NETWARE is needed around the call) This at least avoids adding a field to the end of the cgi structure allocated by Apache and passed to modules implementing the optional function, which (at the moment) a minority of people think requires a major bump. *sounds natural to me; that also means that the default is the same on all platforms -- run child in different address space
