ChangeLog

+
+0.2:
+
+    * New FS implementations:
+        * S3FS:    access remote files stored in Amazon S3
+        * RPCFS:   access remote files using a simple XML-RPC protocol
+        * SFTPFS:  access remote files on a SFTP server
+        * WrapFS:  filesystem that wraps an FS object and transparently
+                   modifies its contents (think encryption, compression, ...)
+    * Ability to expose FS objects to the outside world:
+        * expose.fuse:    expose an FS object using FUSE
+        * expose.xmlrpc:  expose an FS object a simple XML-RPC protocol
+        * expose.sftp:    expose an FS object SFTP
+        * expose.django_storage:  convert FS object to Django Storage object
+    * fs.remote:  utilities for implementing FS classes that interface
+                  with a remote filesystem
+    * Extended attribute support (getxattr/setxattr/delxattr/listxattrs)
+    * Renamed "fs.helpers" to "fs.path", and renamed to contained functions
+      to match those offered by os.path
+

NOTES.txt

-
-Rename 'helpers' module to 'path' since it's basically an imitation of os.path.
-Minify the contained functions:
-   - make normpath() do more e.g. collapse backrefs
-   - remove resolvepath() as it just confuses the issue
-   - resourcename() -> basename() in line with os.path notation
-   - remove isabsolutepath(), it wasn't used
-
-Put error class definitions in separate submodule 'errors'
-   - less redundancy (e.g. no more `raise UnsupportedError("UNSUPPORTED")`)
-   - deeper exception heirachy (e.g. `ParentDirectoryMissingError`)
-This is designed to allow me to be more optimistic; rather than checking all
-preconditions before trying an action, I can just let it fail and branch on
-the exception.  Important for reducing the number of accesses to a remote FS.
-
-Remove the notion of hidden files from the base FS class.
-   - has lead to several bugs with copying/moving directories
-   - it's not the filesystem's business to decide what files I want to see
-   - moved the logic into a separate wrapper class "HideDotFiles"
-
-Remove xattr support from base FS class, making it a separate interface.
-   - has lead to several bugs with copying/moving files and directories
-   - now defined in fs.xattrs module
-   - SimulateXAttr wrapper class contains the same logic
-   - removexattr() -> delxattr() in line with python's get/set/del tradition
-
-Operational changes to the base methods:
-   - don't require makedir() to support the "mode" argument, since this only
-     makes sense for OS-level files.
-   - when copy() is given an existing directory as destination, raise an error
-     rather than copying into the directory (explicit is better than implicit)
-
-Split up the test definitions a little:
-   - use a separate FSTestCases mixin rather than subclassing TestOSFS
-   - path helpers testcases in their own module
-   - zipfs in its own module since it's different to all the others
-   - s3fs in its own module since it's very slow and costs money to test
