Urbit is a personal server for self-sovereign personal & networked
|
|
computing. Nock, a functional combinator, is built into Hoon, a system
|
|
programming language, used to implement Arvo, a deterministic operating
|
|
system, that communicates over Ames, a decentralized, encrypted P2P network.
|
|
|
|
|
|
This app helps you boot and manage Urbit instances on your Umbrel. It provides a simple management GUI, start and stop operations, and passes your +code through the interface.

releaseNotes: >-
|
|
The big ticket items for this vere release include the epoch system,
|
|
support for persistent nock caching, informal pings and MDNS local
|
|
routing. The epoch system is functional immediately after upgrading to
|
|
vere-v3.0, the other features are reliant on the 411k release slated for
|
|
~2024.3.18.
|
|
|
|
|
|
This release is not backwards compatible with vere-v2.12 and earlier. A
|
|
ship cannot be downgraded after upgrading to vere-v3.0.
|
|
|
|
|
|
Epoch System:
|
|
|
|
|
|
The epoch system cuts the previously uniform event log into “epochs”
|
|
associated with a specific runtime version. The epochs are represented
|
|
as directories in the file system. Here is an example of epochs under
|
|
the Foundation galaxy ~deg that has been running the vere-v3.0
|
|
pre-release for a while:
|
|
|
|
|
|
bash ls ./deg/.urb/log/ 0i0 0i95419173 0i98550959 0i99182407 0i99543593
|
|
data.mdb lock.mdb
|
|
|
|
|
|
Each epoch folder is identified by an event number and includes a
|
|
snapshot and a part of the event log. If the snapshot of a ship gets
|
|
corrupted the ship may have to replay; the epoch system makes this
|
|
process more pleasant since the ship no longer has to replay the entire
|
|
event log. A replay can be initiated from the latest valid epoch,
|
|
significantly speeding up the process.
|
|
|
|
|
|
The latest snapshot for a ship is situated in the latest epoch,
|
|
0i99543593 in the above case. All other epochs are safe to relocate
|
|
elsewhere or even delete.
|
|
|
|
|
|
The default behavior for the epoch system is to create a new epoch every
|
|
time the vere runtime version changes. A user may also manually create a
|
|
new epoch by using the urbit roll command.
|
|
|
|
|
|
The urbit chop command now deletes all epochs except for the last two.
