In order to curb event queue growth when a client for whatever reason isn't acking the events we send out, we implement a mechanism for detecting such "clogging", and proactively kick subscriptions which are adding too many events to the queue. If the client hasn't sent an ack for ~s30, any subscription that accrues more than 50 unacked %facts gets closed to prevent further buildup. Upon reconnecting, the client will see %kick for the relevant subscriptions and can open a new subscription as appropriate. Includes a simple test for this behavior, and updates /app/dbug to be able to display the newly tracked statistics. |

Urbit
Urbit is a personal server stack built from scratch. It has an identity layer (Azimuth), virtual machine (Vere), and operating system (Arvo).
A running Urbit "ship" is designed to operate with other ships peer-to-peer. Urbit is a general-purpose, peer-to-peer computer and network.
This repository contains:
- The Arvo OS
- herb, a tool for Unix control of an Urbit ship
- Source code for Landscape's web interface
- Source code for the vere virtual machine.
For more on the identity layer, see Azimuth. To manage your Urbit identity, use Bridge.
Install
To install and run Urbit, please follow the instructions at urbit.org/using/install. You'll be on the live network in a few minutes.
If you're interested in Urbit development, keep reading.
Development
Urbit uses Nix to manage builds. On Linux and macOS you can install Nix via:
curl -L https://nixos.org/nix/install | sh
The Makefile in the project's root directory contains useful phony targets for building, installing, testing, and so on. You can use it to avoid dealing with Nix explicitly.
To build the Urbit virtual machine binary, for example, use:
make build
The test suite can similarly be run via a simple:
make test
Note that some of the Makefile targets need access to pills tracked via git LFS, so you'll also need to have those available locally:
git lfs install
git lfs pull
