Until now, clients of Jael have had to store the first-seen rift if they want to reliably detect breaches. Otherwise, they would get a false positive if they heard an old message about a breach (eg if you kick azimuth-tracker). Clay and Gall did this correctly, but Ames did not. Jael already maintains this state, so I added a notification to the existing subscription that happens whenever it notices a breach (a diff or full where the new rift is greater than the old one). Because this is an issue on the live network, I wrote state adapters for Gall and Clay. The Gall one just removes the rift from our state, but the Clay one is much more involved because we have to upgrade instances of the clad monad that are possibly in progress. Specifically, since more input is possible than before, we must wrap any in-progress instances of the monad in a function that handles the potential new input from Jael. This temporarily preservers a copy of the old kernel, but only until the current commit/merge/update has completed. The real solution for Clay is to factor out those IO-heavy instances to userspace tapp/async/imp/threads, and if an upgrade happens in the middle, you should simply restart them. Fixes #1852 |

Urbit
A personal server operating function.
The Urbit address space, Azimuth, is now live on the Ethereum blockchain. You can find it at
0x223c067f8cf28ae173ee5cafea60ca44c335fecborazimuth.eth. Owners of Azimuth points (galaxies, stars, or planets) can view or manage them using Bridge, and can also use them to boot Arvo, the Urbit OS.
Install
To install and run Urbit, please follow the instructions at urbit.org/docs/getting-started/. 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 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 Urbit, 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
