The "tahoe backup" command has been improved to skip over unreadable objects
(like device files, named pipes, and files with permissions that prevent the
command from reading their contents), instead of throwing an exception and
terminating the backup process. It also skips over symlinks, because these
cannot be represented faithfully in the Tahoe-side filesystem. A warning
message will be emitted each time something is skipped. (#729, #850, #641)
*** "create-node" command added, "create-client" now implies --no-storage
The basic idea behind Tahoe's client+server and client-only processes is that
you are creating a general-purpose Tahoe "node" process, which has several
components activated (or not). Storage service is one of these optional
components, as is the Helper, FTP server, and SFTP server. (Client/webapi
functionality is nominally on this list, but it is always active: a future
release will make it optional). The special-purpose servers remain separate
(introducer, key-generator, stats-gatherer).
So now "tahoe create-node" will create a Tahoe node process, and after
creation you can edit its tahoe.cfg to enable or disable the desired
services. It is a more general-purpose replacement for "tahoe create-client".
The default configuration has storage service enabled. For convenience, the
"--no-storage" argument makes a tahoe.cfg file that disables storage service.
"tahoe create-client" has been changed to create a Tahoe node without a
storage service. It is equivalent to "tahoe create-node --no-storage". This
helps to reduce the confusion surrounding the use of a command with "client"
in its name to create a storage *server*. Use "tahoe create-client" to create
a purely client-side node. If you want to offer storage to the grid, use
"tahoe create-node" instead.
In the future, other services will be added to the node, and they will be
controlled through options in tahoe.cfg . The most important of these
services may get additional --enable-XYZ or --disable-XYZ arguments to "tahoe
create-node".

The webapi acquired a new "t=mkdir-with-children" command, to create and The webapi acquired a new "t=mkdir-with-children" command, to create and
populate a directory in a single call. This is significantly faster than populate a directory in a single call. This is significantly faster than
using separate "t=mkdir" and "t=set_children" operations (it uses one using separate "t=mkdir" and "t=set-children" operations (it uses one
gateway-to-grid roundtrip, instead of three or four). gateway-to-grid roundtrip, instead of three or four).
The t=set_children operation is now documented in docs/frontends/webapi.txt . The t=set-children (note the hyphen) operation is now documented in
docs/frontends/webapi.txt, and is the new preferred spelling of the old
t=set_children (with an underscore). The underscore version remains for
backwards compatibility.
Several small packaging improvements were made to facilitate the "tahoe-lafs" The tracebacks produced by errors in CLI tools should now be in plain text,
instead of HTML (which is unreadable outside of a browser). (#646)
The [storage]reserved_space configuration knob (which causes the storage
server to refuse shares when available disk space drops below a threshold)
should work on windows now, not just unix. (#637)
"tahoe cp" should now exit with status "1" if it cannot figure out a suitable
target filename, such as when you copy from a bare filecap. (#761)
"tahoe get" no longer creates a zero-length file upon error. (#121)
"tahoe ls" can now list single files. (#457)
"tahoe deep-check --repair" should tolerate repair failures now, instead of
halting traversal. (#874, #786)
