<div>Hello,</div>
<div> </div>
<div>You need to patch Twisted to use sftp with Tahoe-LAFS</div>
<div> </div>
<div>You can follow instructions in chapter "Dependencies" in file docs / frontends / FTP-and-SFTP.txt [1]</div>
<div> </div>
<div>Regards</div>
<div>Frederic</div>

Tahoe-LAFS v1.7.<br><br>The current version passes our comprehensive test suite on many<br>platforms (see the Buildbot [1] especially the "Supported Platforms"<br>section).<br><br>This is officially Tahoe-LAFS v1.7.0â!<br>
<br>The plan is that this version will become v1.7.0 final except for<br>improving the documentation and packaging, and fixing any critical<br>bugs that turn up.<br><br>Tahoe-LAFS v1.7 is going to be a major new release, adding important<br>
features and continuing our strong tradition of reliability and<br>compatibility.<br><br><br>WHAT'S NEW<br><br>There are three major new features (not counting various small<br>bugfixes and improvements): SFTP support, support for non-ASCII<br>
character encodings, and Servers of Happiness.<br><br>* SFTP support<br><br>Your Tahoe-LAFS gateway now acts like a full-fledged SFTP server. It<br>has been tested with sshfs to provide a virtual filesystem in Linux.<br>Many users have asked for this feature. We hope that it serves them<br>
well! See the FTP-and-SFTP.txt document [2] to get started.<br><br>* support for non-ASCII character encodings<br><br>Tahoe-LAFS now correctly handles filenames containing non-ASCII<br>characters on all supported platforms:<br>
<br> - when reading files in from the local filesystem (such as when you<br>run "tahoe backup" to back up your local files to a Tahoe-LAFS grid);<br> - when writing files out to the local filesystem (such as when you<br>
run "tahoe cp -r" to recursively copy files out of a Tahoe-LAFS grid);<br> - when displaying filenames to the terminal (such as when you run<br>"tahoe ls"), subject to limitations of the terminal and locale;<br>
- when parsing command-line arguments, except on Windows (to be fixed<br>on Windows in a future release)<br><br>* Servers of Happiness<br><br>Tahoe-LAFS now measures during immutable file upload to see how well<br>distributed it is across multiple servers. It aborts the upload if the<br>
pieces of the file are not sufficiently well-distributed.<br><br>This behavior is controlled by a configuration parameter called<br>"servers of happiness". With the default settings for its erasure<br>coding, Tahoe-LAFS generates 10 shares for each file, such that any 3<br>
of those shares are sufficient to recover the file. The default value<br>of "servers of happiness" is 7, which means that Tahoe-LAFS will<br>guarantee that there are at least 7 servers holding<br>some of the shares, such that any 3 of those servers can completely<br>
recover your file.<br><br>The new upload code also distributes the shares better than the<br>previous version in some cases and takes better advantage of<br>pre-existing shares (when a file has already been previously<br>
uploaded). See the architecture.txt document [3] for details.<br><br><br>HOW TO GET STARTED<br><br>Follow the instructions in the quickstart.html document [4].<br><br><br>CAVEATS<br><br>Do not be too disappointed if you discover the following performance issue.<br>
<br>While this release makes it possible to use Tahoe-LAFS as a mostly<br>POSIX-compliant filesystem (thanks to FUSE and sshfs), it will have<br>very bad performance for some cases which have good performance on<br>your traditional local filesystem. In particular it is bad at making<br>
small changes to large files (it actually stores the new file contents<br>every time you write to the file and re-uploads the entire file every<br>time you close it after having written to it). On the other hand it<br>has some nice scalability and load-balancing characteristics compared<br>
to traditional POSIX filesystems—you will be able to easily add tens<br>or hundreds of computers to your distributed, shared Tahoe-LAFS<br>filesystem and it will take advantage of them in a nice distributed<br>pattern without going noticeably slower than if you had a single<br>
Tahoe-LAFS server.<br><br>So, you should not assume that the POSIX emulation of Tahoe-LAFS v1.7<br>will perform sufficiently well at a particular use case or load<br>pattern until you've tried it, but if you do try it and it does<br>
perform acceptably well then you can feel confident that it will<br>continue to perform that well as you scale out your filesystem.<br><br>Improving the performance in some dimensions is one of the goals of<br>the Google Summer of Code Project which will result in Tahoe-LAFS v1.8<br>
this Fall (northern hemisphere).<br><br><br>COMPATIBILITY<br><br>This release continues the tradition of full backward-compatibility.<br>Use it without fear.<br><br><br>ENJOY!<br><br>We think Tahoe-LAFS is a really cool hack with great potential. That's<br>
why we spend our time on it as a labor of love. We hope you find good<br>uses for it.<br><br><br>Regards,<br><br>Zooko, release manager of v1.7<br><br>[1] <a href="http://tahoe-lafs.org/buildbot/" target="_blank">http://tahoe-lafs.org/buildbot/</a><br>
