@ixv recently uncovered a bug (#2180) in Ford that caused certain rebuilds to crash. @Fang- and I believe this change should fix the bug, and we have confirmed that the reproduction that used to fail about two thirds of the time now has not failed at all in the ten or so times we've run it since then. @Fang- is still running more tests to confirm the fix with more certainty. It turned out the cause was that (depending on the rebuild order, which is unspecified and should not need to be specified), Ford could enqueue a provisional sub-build to be run but then, later in the same +gather call, discover that the sub-build was in fact an orphan and delete it from builds.state accordingly. Then when Ford tried to run the sub-build, it would have already been deleted from the state, so Ford would crash when trying to process its result in +reduce. The fix was to make sure that when we discover a provisional sub-build is orphaned, dequeue it from candidate-builds and next-builds to make sure we don't try to run it. I'm about 95% sure this fix completely solves the bug. |

Urbit
A personal server operating function.
The Urbit address space, Azimuth, is now live on the Ethereum blockchain. You can find it at
0x223c067f8cf28ae173ee5cafea60ca44c335fecb
orazimuth.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
