Release 1.10.1 (2015-06-15)
'''''''''''''''''''''''''''
User Interface / Configuration Changes
--------------------------------------
The "``tahoe cp``" CLI command's ``--recursive`` option is now more predictable,
but behaves slightly differently than before. See below for details. Tickets
`#712`_, `#2329`_.
The SFTP server can now use public-key authentication (instead of only
password-based auth). Public keys are configured through an "account file",
just like passwords. See docs/frontends/FTP-and-SFTP for examples of the
format. `#1411`_
The Tahoe node can now be configured to disable automatic IP-address
detection. Using "AUTO" in tahoe.cfg [node]tub.location= (which is now the
default) triggers autodetection. Omit "AUTO" to disable autodetection. "AUTO"
can be combined with static addresses to e.g. use both a stable
UPnP-configured tunneled address and a DHCP-assigned dynamic (local subnet
only) address. See `configuration.rst`_ for details. `#754`_
The web-based user interface ("WUI") Directory and Welcome pages have been
redesigned, with improved CSS for narrow windows and more-accessible icons
(using distinctive shapes instead of just colors). `#1931`_ `#1961`_ `#1966`_
`#1972`_ `#1901`_

"tahoe cp" changes
------------------
The many ``cp``-like tools in the Unix world (POSIX ``/bin/cp``, the ``scp``
provided by SSH, ``rsync``) all behave slightly differently in unusual
circumstances, especially when copying whole directories into a target that
may or may not already exist. The most common difference is whether the user
is referring to the source directory as a whole, or to its contents. For
example, should "``cp -r foodir bardir``" create a new directory named
"``bardir/foodir``"? Or should it behave more like "``cp -r foodir/* bardir``"?
Some tools use the presence of a trailing slash to indicate which behavior
you want. Others ignore trailing slashes.
"``tahoe cp``" is no exception to having exceptional cases. This release fixes
some bad behavior and attempts to establish a consistent rationale for its
behavior. The new rule is:
- If the thing being copied is a directory, and it has a name (e.g. it's not
a raw Tahoe-LAFS directorycap), then you are referring to the directory
itself.
- If the thing being copied is an unnamed directory (e.g. raw dircap or
alias), then you are referring to the contents.
- Trailing slashes do not affect the behavior of the copy (although putting
a trailing slash on a file-like target is an error).
- The "``-r``" (``--recursive``) flag does not affect the behavior of the
copy (although omitting ``-r`` when the source is a directory is an error).
- If the target refers to something that does not yet exist:
- and if the source is a single file, then create a new file;
- otherwise, create a directory.
There are two main cases where the behavior of Tahoe-LAFS v1.10.1 differs
from that of the previous v1.10.0 release:
- "``cp DIRCAP/file.txt ./local/missing``" , where "``./local``" is a
directory but "``./local/missing``" does not exist. The implication is
that you want Tahoe to create a new file named "``./local/missing``" and
fill it with the contents of the Tahoe-side ``DIRCAP/file.txt``. In
v1.10.0, a plain "``cp``" would do just this, but "``cp -r``" would do
"``mkdir ./local/missing``" and then create a file named
"``./local/missing/file.txt``". In v1.10.1, both "``cp``" and "``cp -r``"
create a file named "``./local/missing``".
- "``cp -r PARENTCAP/dir ./local/missing``", where ``PARENTCAP/dir/``
contains "``file.txt``", and again "``./local``" is a directory but
"``./local/missing``" does not exist. In both v1.10.0 and v1.10.1, this
first does "``mkdir ./local/missing``". In v1.10.0, it would then copy
the contents of the source directory into the new directory, resulting
in "``./local/missing/file.txt``". In v1.10.1, following the new rule
of "a named directory source refers to the directory itself", the tool
creates "``./local/missing/dir/file.txt``".
Compatibility and Dependency Updates
------------------------------------
Windows now requires Python 2.7. Unix/OS-X platforms can still use either
Python 2.6 or 2.7, however this is probably the last release that will
support 2.6 (it is no longer receiving security updates, and most OS
distributions have switched to 2.7). Tahoe-LAFS now has the following
dependencies:
- Twisted >= 13.0.0
- Nevow >= 0.11.1
- foolscap >= 0.8.0
- service-identity
- characteristic >= 14.0.0
- pyasn1 >= 0.1.4
- pyasn1-modules >= 0.0.5
On Windows, if pywin32 is not installed then the dependencies on Twisted
and Nevow become:
- Twisted >= 11.1.0, <= 12.1.0
- Nevow >= 0.9.33, <= 0.10
On all platforms, if pyOpenSSL >= 0.14 is installed, then it will be used,
but if not then only pyOpenSSL >= 0.13, <= 0.13.1 will be built when directly
invoking `setup.py build` or `setup.py install`.
We strongly advise OS packagers to take the option of making a tahoe-lafs
package depend on pyOpenSSL >= 0.14. In order for that to work, the following
additional Python dependencies are needed:
- cryptography
- cffi >= 0.8
- six >= 1.4.1
- enum34
- pycparser
as well as libffi (for Debian/Ubuntu, the name of the needed OS package is
`libffi6`).
Tahoe-LAFS is now compatible with Setuptools version 8 and Pip version 6 or
later, which should fix execution on Ubuntu 15.04 (it now tolerates PEP440
semantics in dependency specifications). `#2354`_ `#2242`_
Tahoe-LAFS now depends upon foolscap-0.8.0, which creates better private keys
and certificates than previous versions. To benefit from the improvements
(2048-bit RSA keys and SHA256-based certificates), you must re-generate your
Tahoe nodes (which changes their TubIDs and FURLs). `#2400`_

Packaging
---------
A preliminary OS-X package, named "``tahoe-lafs-VERSION-osx.pkg``", is now
being generated. It is a standard double-clickable installer, which creates
``/Applications/tahoe.app`` that embeds a complete runtime tree. However
launching the ``.app`` only brings up a notice on how to run tahoe from the
command line. A future release may turn this into a fully-fledged application
launcher. `#182`_ `#2393`_ `#2323`_
Preliminary Docker support was added. Tahoe container images may be available
on DockerHub. `PR#165`_ `#2419`_ `#2421`_
Old and obsolete Debian packaging tools have been removed. `#2282`_
