grahamcofborg

Guidelines

1. make sure you've reviewed the code before you trigger it on a PR that isn't your own
2. be gentle, preferably don't run mass rebuilds / massive builds like chromium on it

Commands

The comment parser is line-based, so comments can be interleaved with instructions.

1. To trigger the bot, the line must start with a case insensitive version of @GrahamcOfBorg.
2. To use multiple commands, insert a bit of whitespace and then your new command.

Commands:

test (added: 2017-11-24)

@grahamcofborg test list of tests

This will run nix-build ./nixos/release.nix -A tests.list -A tests.of -A tests.attrs in the nixpkgs checkout. Note: this will only run on x86_64-linux machines.

eval

@grahamcofborg eval

Note: Every PR automatically evaluates when it is opened and when the commits change. There is no reason to run eval on a PR unless the evaluation has failed for weird reasons, or because master was broken before.

build

@grahamcofborg build list of attrs

This will run nix-build ./default.nix -A list -A of -A attrs in the nixpkgs checkout.

---

Multiple Commands:

@grahamcofborg build list of attrs
@grahamcofborg eval

or even:

@grahamcofborg build list of attrs @grahamcofborg eval

This will also work:

looks good to me!
@grahamcofborg build list of attrs

And this is fine:

@grahamcofborg build list of attrs
looks good to me!

This is will build list, of, attrs, looks, good, to, me!:

@grahamcofborg build list of attrs looks good to me!

How does OfBorg call nix-build?

Builds are run like:

HOME=/homeless-shelter NIX_PATH=nixpkgs=$(pwd) nix-build ./default.nix --no-out-link --keep-going -A hello --option restrict-eval true --option build-timeout 1800 --argstr system thesystem --show-trace

How does OfBorg call nix-instantiate?

NixOS evals are run like:

HOME=/homeless-shelter NIX_PATH=nixpkgs=$(pwd) nix-instantiate ./nixos/release.nix -A manual --option restrict-eval true --option build-timeout 1800 --argstr system thesystem --show-trace

Nixpkgs evals are run like:

HOME=/homeless-shelter NIX_PATH=nixpkgs=$(pwd) nix-instantiate ./pkgs/top-level/release.nix -A manual --option restrict-eval true --option build-timeout 1800 --argstr system thesystem --show-trace

---

Running a builder

nix-shell ./shell.nix
$ cd ofborg
$ cargo build

cargo build

then copy example.config.json to config.json and edit its vars. Set nix.remote to an empty string if you're not using the daemon.

Run

./target/debug/builder ./config.json
