[[https://one.ubuntu.com/|Ubuntu One]] is a suite of online services from [[http://canonical.com/|Canonical]]. The service enables users to store and sync files online and between computers and share files and folders with others using file synchronization. Unlike the traditional storage application and service, what sets Ubuntu One apart is additional features like the integration with other services. Ubuntu One offers integration with Evolution for syncing contacts and with Tomboy for notes due to the access to the local CouchDB instance. Further possibilities include the capability of editing the contacts, as well as the Tomboy notes, online via the Ubuntu One Web interface. <<BR>> |

| -------------------------------------- = Technical details = * ''Details as viewed by an outsider. Blame sladen for E&OE and for the insistence on using cute names.'' As of 2009-06-08, these are: * '''Storage''': remote storage Because of the fuzzy nature of the "Ubuntu One" branding and because of the long-winded names of the components; this document uses unique, generic names to ''succinctly'' describe each of the components and layers. You can find a table mapping these simple names to download packages and URLs at the bottom. (See the "storagefs" section for just how long-winded and inconvenient these actual names can get). "Ubunet" appears to be the name of the whole project/development team, as can be found in Launchpad (in addition to a "control tower" team group). == "Storage" == This provides 2GB-10GB of remotely accessible disk space stored on Amazon S3. Rather than using an existing protocol (eg. FTP, SFTP, NFS, Webdav) access to this remote disk space is via a not-invented-here communication protocol called "u1storage". The system is intented to be for ''mirroring'' of content, then keeping each of those mirrors synchronised. It is possible to share a directory view (called a "Share") between multiple near-instantaneous users and multiple near-instantaneous connections. There is a delay because a file must be completely uploaded before the changes can start to be shared. The heavy duty backend storage is ultimately out-sourced to [[http://aws.amazon.com/s3/|Amazon S3]] (Amazon Simple Storage Service). At a high-level, ''Storage'' has been compared to [[http://www.getdropbox.com/install?os=lnx|Dropbox]]. In June 2009, Mandriva have produced something similar called [[http://www2.mandriva.com/mdvbackup/|mdvbackup]], (branded as "Mandriva Click'n'Backup"). ''A previous, possibly unused(?), codename for this facility appears to have been "Hammertime".'' === updown === This is a HTTP/web-browser interface to view files held in the storage service. It allows viewing of files, and uploading and downloading. Collections of files (Shares) held by the user are displayed under "My Files". It is universal and cross-platform. An advantage is that it allows direct "cherry picking" of individual files, without waiting for synchronisation first. (Long term personal hunch; I suspect people will just poll/screenscape the updown interface, a la GmailFS). Going via the browser appears to be "closest to bare metal" interface. It apparently does not use the "u1storage" protocol for access, so is probably talking straight to Amazon S3. There is one implementation, which is proprietary. Little is known, but an instance of it runs at https://www.ubuntuone.com/files/ (subscribers only). === u1storage === This protocol is built on top of Google [[http://code.google.com/apis/protocolbuffers/docs/overview.html|Protocol Buffers]] (a sort of fast binary XMLish schema language). This abstraction is to allow extension of the `u1storage` protocol with breaking compatibility. The intention of the protocol is to enabling synchronisation by mirroring of content. The protocol itself uses SHA-1 hashes as identifiers for directory objects and their contents (files). Requests are always initiated from the client end. The first versions does not support any kind of delta-optimisation and each object (file) must be sent in its entirety. Currently there is only one implementation, it written in Python and called `python-u1storage` (AGPLv3+copyright assignment required). The `.proto` descriptions (AGPLv3+assignment) can be used as starting points for other language implementations. ==== storagefsd ==== This is the fuzzy term for a monolithic(?) deamon running on the server `fs-1.ubuntuone.com` (174.129.241.144, currently an Amazon EC2 virtual machine instance). It accepts incoming SSL/TLS wrapped `u1storage` connections on port 443. Note that although port 443 (HTTPS) is used to allow passage through firewalls, the protocol has nothing to do with HTTP. Storagefsd sends a client connected via the u1storage protocol unsolicited updates of any hash reference that have been updated, so that the other end can re-download the changed objects. Currently there is one implementation, which is proprietary. This links to `python-u1storage`. That implemetnation is started by `/etc/init.d/ubuntuoneapiserver` which probably executes something like `/usr/bin/env python .../canonical/ubuntuone/storage/server/server.py`. <small>(Doesn't exactly trip off the tongue...).</small> It seems to save the partially uploaded files to a temporary directory; then presumably indexes/moves them off to Amazon S3 where the real storage is. ==== u1sync-agent ==== This is a per-user daemon run on each desktop computer and has no user interface. It runs in the background and exposes a DBus API interface. The agent does the actual work of deciding what to sychronise in which direction and handles doing so. Automatic resumption and partial uploading/downloading is supported, these files will be visible as `filename.partial` until the transfer has completed, when they are required to the proper filename. By default, one fold called `~/Ubuntu One/` is automatically created and configured for mirroring. Changes to this fold (and any others added) are watched using inotifiy. Synchronisation meta-data about which directories are being mirrored and what their is stored in `~/.cache/ubuntuone`. When remote content has changed, the agent acts on the incoming unsolicated notification sent by storagefs and starts downloading. Authenication is via OAuth. Passwords are securely stored via the `gnome-keyring` service. There is one implementation, written in Python (GPLv3), this may also be referred to as ''chicharra''. It is started by `/usr/share/dbus-1/services/com.ubuntuone.SyncDaemon.service` and exposes its DBus interface under `com.ubuntuone.SyncDaemon`. Logs files are kept in `~/.cache/ubuntuone/log/syncdaemon.log`. ===== gnome-u1sync-applet ===== Tray icon to control the behaviour of the a running `u1sync-agent` instance, by communicating over the DBus interface. Provides a constant status update on "what's happening". There is one implementation, which is written in Python (GPL+copyright assignment hassle status unknown). ===== u1sync-tool ===== Command line utility to control the behaviour of a running `u1sync-agent` instance. The tool does not perform any actions directly, but sends messages to the running agent. There is one implementation, which is written in Python (GPLv3). ===== libnautilus-u1sync ===== An extension (plugin) for the default GNOME file-browser called Nautilus to adds a status icon/button. This can send connection and disconnection requests to a running `u1sync-agent` instance. Additions directories (Shares) can be nominated for sharing using a new right-click context menu. There are two implementations. One currently being shipped, written in Python (GPLv3), and one written in C (GPLv3) under development as of 2009-06-08. ==== u1ftp ==== This is a command line and test utility tool more akin to `bzr branch/push` or `git clone/push` (version control systems). It is ''incompatible'' with the rest of the u1sync-agent infrastructure. Synchronisation metadata is stored in a hidden directory at the root folder of each share named `$dir/.ubuntuone-sync`. Apparently, this utility has concepts borrowed from Amazon's [[http://s3.amazonaws.com/ServEdge_pub/s3sync/README.txt|s3sync]] tool. There is one implementation, which is written in Python (GPLv3). ==== fuse-u1storage ==== Apparently there was a FUSE (Filesystem in User Space) implementation, but it was "a disaster", so probably got canned. No details on whether this worked via mirroring, or simply exposing/mounting the remote filesystem locally. There are zero current implementations. == Name mappings == || '''This document''' || '''Canonical name''' || '''Bugs''' || '''Source''' || || updown || updown || [[https://bugs.launchpad.net/ubunet/+bugs|ubunet]] || ??, n/a || || storagefsd || ubuntuoneapiserver || [[https://bugs.launchpad.net/ubunet/+bugs|ubunet]] || Python, n/a || || u1storage || ubuntuone-storage-protocol || [[https://bugs.launchpad.net/ubuntuone-storage-protocol/+bugs|ubuntone-storage-protocol]] || Python, AGPLv3 [[http://bazaar.launchpad.net/~ubuntuone-control-tower/ubuntuone-storage-protocol/trunk/changes|u-s-p/trunk]] || || u1sync-agent || ubuntuone-syncdaemon || [[https://bugs.launchpad.net/ubuntuone-client/+bugs|ubuntone-client]] || Python, GPLv3 || || u1sync-tool || u1sdtool || [[https://bugs.launchpad.net/ubuntuone-client/+bugs|ubuntone-client]] || Python, GPLv3 || || gnome-u1sync-applet || ubuntuone-client-applet || [[https://bugs.launchpad.net/ubuntuone-client/+bugs|ubuntone-client]] || Python, GPLv3 || || libnautilus-u1sync || ubuntuone-nautilus || [[https://bugs.launchpad.net/ubuntuone-client/+bugs|ubuntone-client]] || Python/C, GPLv3 || || u1ftp || u1sync || [[https://bugs.launchpad.net/ubuntuone-client/+bugs|ubuntone-client]] || Python, GPLv3 || || fuse-u1storage || ?? || ?? || ??, n/a || |
