It has been +tested with sshfs to provide a virtual filesystem in Linux. Many users have +asked for this feature. We hope that it serves them well! See the +docs/frontends/FTP-and-SFTP.txt document to get started. + +*** support for non-ASCII character encodings + +Tahoe-LAFS now correctly handles filenames containing non-ASCII characters on +all supported platforms: + - when reading files in from the local filesystem (such as when you run "tahoe + backup" to back up your local files to a Tahoe-LAFS grid); + - when writing files out to the local filesystem (such as when you run "tahoe + cp -r" to recursively copy files out of a Tahoe-LAFS grid); + - when displaying filenames to the terminal (such as when you run "tahoe ls"), + subject to limitations of the terminal and locale; + - when parsing command-line arguments, except on Windows. + +*** Servers of Happiness + +Tahoe-LAFS now measures a file during upload to see how well distributed it is +across multiple servers. It aborts the upload if the pieces of the file are +not sufficiently well-distributed. This behavior is controlled by a +configuration parameter called "servers of happiness". With default settings +Tahoe-LAFS generates 10 shares for each file, such that any 3 of those shares +are sufficient to recover the file. The default value of "servers of +happiness" is 7, which means that Tahoe-LAFS will guarantee that there are at +least 7 servers holding some of the shares, such that any 3 of those servers +can completely recover your file. The new upload code also distributes the +shares better than the previous version in some cases and takes better +advantage of pre-existing shares (when a file has already been previously +uploaded). See the docs/architecture.txt document [3] for details. -In the case where Tahoe encounters a filename which cannot be decoded using the -system encoding, an error will be returned and the operation will fail. Under -Linux, this typically happens when the filesystem contains filenames encoded -with another encoding, for instance latin1, than the system locale, for -instance UTF-8. In such case, you'll need to fix your system with tools such -as 'convmv' before using Tahoe CLI. +** Bugfixes -All CLI commands have been improved to support non-ASCII parameters such as -filenames and aliases on all supported Operating Systems. + - Premature abort of upload if some shares were already present and some + servers fail.
