Again, hello everyone. It has taken me a bit longer than I expected, but the current state of my repository is that it can be merged (modulo possible bugs), and further additions won't have so much impact on the rest of the system as they had until now.
The biggest visible change from the mainline is currently that I have removed most of the POSIX-like file management functions (which were non-standard anyway), and created a new library called VCL (VFS Client Library), that is far closer to root-less VFS API than POSIX functions. The client library is somewhat different from what I implemented in my bc. thesis, but I think it's better and easier to use. As always, bugs are possible, and in some cases likely. Specifically, I have not tested libposix and applications that depend on it beyond "it builds". The same can be said for any architecture other than ia32. I have not made much effort to test bdsh, since most of it should to be completely rewritten. I promise to fix any discovered problems promptly. Current TODO with respect to VFS: - implement union binding in libc - implement shell commands that can take advantage of new features - specify and implement a directory structure for interactive applications and user accounts - figure out what other changes in the system are necessary to make it really impossible for evil programs/users to do bad stuff PS.: I have not yet merged recent mainline changes, but I am working on it. -- Jirka Z.
