Is there a question or a request in here somewhere? If not, c.l.py.ann would be more appropriate.
If you want that code integrated into core Python, read python.org/dev and prepare a patch for SF! --Guido On 4/30/06, Heiko Wundram <[EMAIL PROTECTED]> wrote: > Hi all! > > I've implemented recvmsg and sendmsg for the socket module in my private > Python tree for communication between two forked processes, which are > essentially wrappers for proper handling of SCM_RIGHTS and SCM_CREDENTIALS > Unix-Domain-Socket messages (which are the two types of messages that are > defined on Linux). > > The main reason I need these two primitives is that I require (more or less > transparent) file/socket descriptor exchange between two forked processes, > where one process accepts a socket, and delegates processing of the socket > connection to another process of a set of processes; this is much like a > ForkingTCPServer, but with the Handler-process prestarted. > > As connection to the Unix-Domain-Socket is openly available, the receiving > process needs to check the identity of the first process; this is done using > a getsockopt(SO_PEERCRED) call, which is also handled more specifically by my > socket extension to return a socket._ucred-type structure, which wraps the > pid/uid/gid-structure returned by the corresponding getsockopt call, and also > the socket message (SCM_CREDENTIALS) which passes or sets this information > for the remote process. > > I'd love to see these two socket message primitives (of which the first, > SCM_RIGHTS, is available on pretty much any Unix derivative) included in a > Python distribution at some point in time, and as I've not got the time to > push for an inclusion in the tree (and even less time to work on other Python > patches myself) at the moment, I thought that I might just post here so that > someone interested might pick up the work I've done so far and check the > implementation for bugs, and at some stage these two functions might actually > find their way into the Python core. > > Anyway, my private Python tree (which has some other patches which aren't of > general interest, I'd think) is available at: > > http://dev.modelnine.org/hg/python > > and I can, if anyone is interested, post a current diff of socketmodule.* > against 2.4.3 to the Python bug tracker at sourceforge.
