[Relfs-devel] Query-FS - alternative core for RelFS (and more) in Common Lisp

[Michael R. <fb0...@ra...>]

		Hello.
	I have updated a ton of things in Query-FS project recently and today I
uploaded a "closed" Query-FS source snapshot + dependencies to
common-lisp.net . See http://mtn-host.prjek.net/projects/cl-fuse/ for
details of installation - you need SBCL and GCC to be installed (and tar
and gzip are hard to avoid on Unix-like systems).
	The idea behind Query-FS is layering, creating DSLs and using Lisp for
DSLs. There are many layers in creating an FS that can run SQL SELECT's
over files. In Query-FS there are two-layered Common Lisp FUSE bindings
(you don't need to understand their inner workings even for developing
Query-FS), management of the non-core code (plugins and queries),
plugins - parsers of DSLs for queries and queries themselves.
	My idea is that large files should not be stored on QueryFS itself,
they should be stored on a dedicated filesystem and QueryFS should just
provide symlinks. I also guess that it is better to have separate
indexers (maybe even using inotify+periodical scrubbing).
	Among other things, there is possibility SQL queries that return
filesystem objects.
	
	Does anyone want to try this out? I am ready to help with installation.
Does anyone think that it is a good foundation for replacing RelFS? Does
anyone have any suggestion for further changes (what plugins should do,
what DSL should be etc)? Should this be mentioned on relfs.sf.net?

	Thanks, good bye
