Ticket #534: unicode-v3.dpatch

Wed Apr  1 10:15:17 CEST 2009  francois@ctrlaltdel.ch
  * CLI: Improved handling of non-ascii filenames
  
  The patch allows users to pass non-ascii filenames to the Tahoe CLI, it stores
  aliase names as UTF-8 and fix handling of non-ascii filenames on commands like
  tahoe cp or tahoe backup.
  
  As Tahoe internal filename storage is unicode, we have to decode the parameters
  we received according to the alleged filesystem encoding which varies depending
  on the platform.
  
  On Windows and MacOS X, the filesystem make uses of unicode strings so no
  decoding should ever happen.
  
  On Linux, the filesystem stores only bytestrings we have to be interepreted
  according to the current locale configuration. This operation can fail in which
  case an error is raised.

-In Tahoe v1.3.0, passing non-ascii characters to the cli is not guaranteed to
-work, although it might work on your platform, especially if your platform
-uses utf-8 encoding.
+As of Tahoe v1.3.1, filenames containing non-ascii characters are
+supported on the commande line if your terminal is correctly configured
+for UTF-8 support. This is usually the case on moderns GNU/Linux
+distributions.
+
+If your terminal doesn't support UTF-8, you will still be able to list
+directories but non-ascii characters will be replaced by a question mark
+(?) on display.
+
+Reading from and writing to files whose name contain non-ascii
+characters is also supported when your system correctly understand them.
+Under Unix, this is usually handled by locale settings. If Tahoe cannot
+correctly decode a filename, it will raise an error. In such case,
+you'll need to correct the name of your file, possibly with help from
+tools such as convmv.

 This walks slowly through all shares, examining their leases, deciding which
 are still valid and which have expired. Once enabled, it will then remove the
 expired leases, and delete shares which no longer have any valid leases. Note
 that there is not yet a tahoe.cfg option to enable lease-deletion: the
 current code is read-only. A subsequent patch will add a tahoe.cfg knob to
 control this, as well as docs. Some other minor items included in this patch:
 
  tahoe debug dump-share has a new --leases-only flag
  storage sharefile/leaseinfo code is cleaned up
  storage web status page (/storage) has more info, more tests coverage
  space-left measurement on OS-X should be more accurate (it was off by 2048x)
