The only work done by fork - that remains visible after an exec is registration with the proc - server, and the inheritance of various values and ports. All those - inherited values and ports are what get collected up and passed in the - file_exec RPC by an exec call. So we do the proc server registration - here, following the model of fork (see fork.c). We then collect up - the inherited values and ports from this (parent) process following - the model of exec (see hurd/hurdexec.c), modify or replace each value - that fork would (plus the specific changes demanded by ATTRP and - FILE_ACTIONS), and make the file_exec RPC on the requested executable - file with the child process's task port rather than our own.

Possible - solutions include: - * punt to plain fork + exec implementation if addopen was used - ** easy to do - ** gives up all benefits of this implementation in that case - * if addopen was used, don't do any file actions at all here; - instead, exec an installed helper program e.g.: - /libexec/spawn-helper close 3 dup2 1 2 open 0 /file 0x123 0666 exec /bin/foo foo a1 a2 - ** extra exec might be more or less overhead than fork - * could do some weird half-fork thing where the child would inherit - our vm and run some code here, but not do the full work of fork - - XXX Actually, the parent opens the executable file on behalf of - the child, and that has all the same issues. - - I am favoring the half-fork solution.
