Examples are: translators were data is located in a local file (like zipfs, tarfs, rarfs, ...), single file translators (that do content filtering, output of a command, etc), network based filesystems (ftpfs, httpfs, ...), proxy filesystems (like hostmux, usermux, etc..) -- It's possible to specialize the basic translator library and implement new translator classes. This is done using CLOS. -- There is a tree-translator class that makes the managing of a node tree very easy, doing all the work for us, through a simple directory API and implementing the directory callbacks for us. -- There is a simple example (something like zipfs) translator that can expose the directories and file contents of a ZIP file. -- More translator examples include: - - /dev/null translator. - - /dev/zero translator. - - translator that creates a symlink node. - - tmpfs like translator. - - a translator that does proxying between clients and the underlying translator returning all data in upper-case. - - a translator that watches for changes in a file describing the file system structure. - - an IRC translator. - - a categorizer translator: creates a virtual directory containing files listed in a file, each file is categorized with a script. For example, a script can output the music author (in an mp3 file) and then all files will be categorized by author. -- Translator options (manipulated through fsysopts) have a simple and easy to use API. -- All the Mach port manipulation API is available. -- It's possible to send and receive messages. Simple example: -<pre> - (let* ((spec-mixed (make-message-spec :fields '(:string :integer :char :string :integer :real))) - (msg-mixed (make-message :spec spec-mixed)) - (port (port-allocate :right-receive))) - (send-message msg-mixed :remote port :data (list "abc" 42 #\b "cba" 314 3.14)) - (receive-message msg-mixed :source port) ; This returns T on success. - (get-message msg-mixed))) ; Returns '("abc" 42 #\b "cba" 314 3.14) -</pre> -- New message types (like :string, :integer) can be implemented, providing a powerful extension mechanism. -- Creation of symlinks and symlink path resolution. -- Creation of character/block devices, fifos and sockets. -- Patch that opens stdin + stdout to /dev/null. -- Project has been separated into 5 ASDF installable systems: - - hurd-common - - mach - - hurd - - hurd-translator - - tree-translator -- Test cases are now written. - - -### What needs to be done - -- Fix fsys-getroot (block happens in trivfs based translators, when they do RPC's to me when I call fsys_getroot to them) and fetch-root (for passive translators). -- Make the library multithreaded (blocked by the pthread conversion project and the unavailable thread support in CLISP) -- Use the socket stubs? -- More documentation - - -### Project dependencies - -- CLISP -- [CFFI](http://common-lisp.net/project/cffi/) (apt-get installable) -- [Flexi streams](http://www.weitz.de/flexi-streams/) (apt-get installable) -- [Trivial garbage](http://www.cliki.net/trivial-garbage) (not in debian repositories) -- [cl-zip](http://common-lisp.net/project/zip/) (only needed for the zip translator) -- [cl-irc](http://common-lisp.net/project/cl-irc/) (for the irc translator) - - -## To do - -### Documentation -- Manually Bootstrapping a Translator - -### Translation -- Translate the Hurd website to Portuguese? - -## Completed tasks - -### Patches -- http://alioth.debian.org/tracker/index.php?group_id=30628&atid=410472 - - libsvg patch accepted. -- Adapted glibc patch (http://www.schwinge.homeip.net/~thomas/tmp/glibc-patches/0009-2007-07-22-version-of-init-first.c_vs._GCC_4.1.patch.patch) - - http://opensvn.csie.org/leic/hurd/patches/glibc-init-first.patch -- Patch to remove some GNUMach IPC warnings and minor cleanup: - - http://opensvn.csie.org/leic/hurd/patches/gnumach-ipc-warnings.patch -- Website patches that correct some encountered typos: - - http://opensvn.csie.org/leic/hurd/patches/hurd-talk-typo.patch - -### Documentation read - -- GNU/Hurd User's Guide, an introduction to the important concepts and software of the GNU system, written for new users, AKA "GNUbies." -- Towards a New Strategy of OS Design, an architectural overview by Thomas Bushnell, BSG. -- The Hurd, a presentation by Marcus Brinkmann. -- The Hurd Hacking Guide. -- The GNU Mach Reference Manual -- The GNU Hurd Reference Manual -- The Unofficial GNU Mach IPC beginner's guide -- Mach IPC without MIG -- CFFI User's Manual - -### Before selection - -- Uptime program in C and Lisp using CFFI. -- Hello translator. - -## Misc - -### Lisp implementations that run on Hurd - -- Clisp -- ECL -- ? |
