This package is available on Ubuntu -systems as "python-fuse". It is only known to work with ubuntu -package version "2.5-5build1". The latest ubuntu package (version -"1:0.2-pre3-3") appears to not work currently. - -Unfortunately this package appears poorly maintained (notice the wildy -different version strings and changing API semantics), so if you know -of a good replacement pythonic fuse interface, please let tahoe-dev know -about it! - - -Configuration: - -Currently tahoe-fuse.py uses the same ~/.tahoe/private/root_dir.cap -file (which is also the CLI default). This is not configurable yet. -Place a directory cap in this file. (Hint: If you can run "tahoe ls" -and see a directory listing, this file is properly configured.) - - -Commandline: - -The usage is "tahoe-fuse.py ". The mount point needs to -be an existing directory which should be empty. (If it's not empty -the contents will be safe, but unavailable while the tahoe-fuse.py -process is mounted there.) - - -Usage: - -To use the interface, use other programs to poke around the -mountpoint. You should be able to see the same contents as you would -by using the CLI or WUI for the same directory cap. - - -Runtime Behavior Notes: - -Read-only: -Only reading a tahoe grid is supported, which is reflected in -the permission modes. With Tahoe 0.7.0, write access should be easier -to implement, but is not yet present. - -In-Memory File Caching: -Currently requesting a particular file for read causes the entire file to -be retrieved into tahoe-fuse.py memory before the read operation returns! -This caching is reused for subsequent reads. Beware large files. -When transitioning to a finer-grained fuse api, this caching should be -replaced with straight-forward calls to the wapi. In my opinion, the -Tahoe node should do all the caching tricks, so that extensions such as -tahoe-fuse.py can be simple and thin. - -Backgrounding Behavior: -When using the 2.5-5build1 ubuntu package, and no other arguments -besides a mountpoint to tahoe-fuse.py, the process should remain in -the foreground and print debug information. Other python-fuse -versions appear to alter this behavior and may fork the process to -the background and obscure the log output. Bonus points to whomever -discovers the fate of these poor log messages in this case. - -"Investigative Logging": -This prototype is designed to aide in further fuse development, so -currently *every* fuse interface call figures out the process from -which the file system request originates, then it figures out that -processes commandline (this uses the /proc file system). This is handy -for interactive inspection of what kinds of behavior invokes which -file system operations, but may not work for you. To disable this -inspection, edit the source and comment out all of the "@debugcall" -[FIXME: double check python ref name] method decorators by inserting a -'#' so it looks like "#@debugcall" (without quotes). - -Not-to-spec: -The current version was not implemented according to any spec and -makes quite a few dubious "guesses" for what data to pass the fuse -interface. You may see bizarre values, which may potentialy confuse -any processes visiting the files under the mount point. - -Serial, blocking operations: -Most fuse operations result in one or more http calls to the WAPI. -These are serial and blocking (at least for the tested python-fuse -version 2.5-5build1), so access to this file system is quite -inefficient. - - -Good luck! diff --git a/contrib/fuse/impl_a/tahoe_fuse.py b/contrib/fuse/impl_a/tahoe_fuse.py deleted file mode 100644 index a3e15927..00000000 --- a/contrib/fuse/impl_a/tahoe_fuse.py +++ /dev/null @@ -1,476 +0,0 @@ -#! /usr/bin/env python -''' -Tahoe thin-client fuse module. - -See the accompanying README for configuration/usage details. - -Goals: - -- Delegate to Tahoe webapi as much as possible. -- Thin rather than clever.
