`Foolscap <https://github.com/warner/foolscap/>`_
|
||
|
|
an RPC/RMI (Remote Procedure Call / Remote Method Invocation) protocol for use with Twisted
|
||
|
|
|
||
|
|
storage server
|
||
|
|
a Tahoe-LAFS process configured to offer storage and reachable over the network for store and retrieve operations
|
||
|
|
|
||
|
|
storage service
|
||
|
|
a Python object held in memory in the storage server which provides the implementation of the storage protocol
|
||
|
|
|
||
|
|
introducer
|
||
|
|
a Tahoe-LAFS process at a known location configured to re-publish announcements about the location of storage servers
|
||
|
|
|
||
|
|
:ref:`fURLs <fURLs>`
|
||
|
|
a self-authenticating URL-like string which can be used to locate a remote object using the Foolscap protocol
|
||
|
|
(the storage service is an example of such an object)
|
||
|
|
|
||
|
|
:ref:`NURLs <NURLs>`
|
||
|
|
a self-authenticating URL-like string almost exactly like a fURL but without being tied to Foolscap
|
||
|
|
|
||
|
|
swissnum
|
||
|
|
a short random string which is part of a fURL/NURL and which acts as a shared secret to authorize clients to use a storage service
|
||
|
|
|
||
|
|
lease
|
||
|
|
state associated with a share informing a storage server of the duration of storage desired by a client
|
||
|
|
|
||
|
|
share
|
||
|
|
a single unit of client-provided arbitrary data to be stored by a storage server
|
||
|
|
(in practice, one of the outputs of applying ZFEC encoding to some ciphertext with some additional metadata attached)
|
||
|
|
|
||
|
|
bucket
|
||
|
|
a group of one or more immutable shares held by a storage server and having a common storage index
|
||
|
|
|
||
|
|
slot
|
||
|
|
a group of one or more mutable shares held by a storage server and having a common storage index
|
||
|
|
(sometimes "slot" is considered a synonym for "storage index of a slot")
|
||
|
|
|
||
|
|
storage index
|
||
|
|
a 16 byte string which can address a slot or a bucket
|
||
|
|
(in practice, derived by hashing the encryption key associated with contents of that slot or bucket)
|
||
|
|
|
||
|
|
write enabler
|
||
|
|
a short secret string which storage servers require to be presented before allowing mutation of any mutable share
|
||
|
|
|
||
|
|
lease renew secret
|
||
|
|
a short secret string which storage servers required to be presented before allowing a particular lease to be renewed
