SSI
Hello OpenBSD world, Has there been/are there plan to include some SSI functionality for BSD? I've looked into Linux for this and the problem stems from the fact that the kernel has to be patched with the code to perform this functionality. The linux kernel, being a separate entity from the rest of the system, makes it difficult to keep an SSI system up to date kernel wise. BSD seems to develop the kernel and utilities as one, lending itself to easier integration of these features, perhaps? I'd be willing to donate money to the project to see functionality like this implemented! Thoughts? Is there anyone I can speak to about funding a sub project for OpenBSD SSI? Or is it not even being considered? Thanks, Brian

Re: SSI
The SSI I'm talking about would be defined as making multiple separate machines appear as one single system with one single process space, a shared root filesystem, and shared virtual IP. Shared memory doesn't seem that important, except for maybe moving a process from one machine to another.

I'd also imagine the complexity of implementing such a system would make it unattractive to OpenBSD. NFS is already horrible enough. ;P

There are research papers showing that the cost of transferring a process from machine to machine greatly exceeds the incremental increase in CPU availability. Sharing memory across a network, like threads, is almost always the wrong approach to data coherency. Sharing I/O devices across a network has mostly been accomplished, though NFS is a bad example. Synchronizing the mess is, in the general case, impossible. Basically, SSI is one of those traps (like threads, again) that might appeal to the naive but dies horribly once one really looks at the idea. Geoff Steckel

I've updated the port to include it. jakob I just wanted to let you know that I did a make update on the latest source and it worked great (macppc -current). I copied ssi to a cgi-bin directory inside my document root and added - c '/cgi-bin/*' to thttpd command line. It parses SSI statements intended for Apache just fine, with the slight nit that it expects the path to be relative to the cgi-bin when I use virtual as the include type. I just created hardlinks to the included files and that solved the problem. Thanks for the super-fast response!!! As a silly aside, thttpd saved my tunnelbroker.net account. They wanted me to put up a website to prove the tunnel belonged to me, and after hours of tweaking httpd.conf yielded only frustration, I installed thttpd and had it up and running in less than 10 minutes. -- bk
