Misc tips

buildbot user style to make the pulsing pills bearable

@keyframes pulse_animation {
  0% { transform:scale(.9) }
  50% { transform:scale(1) }
  to { transform:scale(.9) }
}

.pulse {
    animation-duration: 10s !important;
}

FIXME: someone should PR this, now that we have the ability to patch buildbot

run all lix vm tests locally

tests=$(
    nix eval --json --impure \
        --apply '
            let f = n: t:
                if __isAttrs t
                then (if t.type or "" == "derivation"
                    then (if t.system == __currentSystem
                            then [ n ]
                            else [])
                    else __concatMap (m: f "${n}.${m}" t.${m}) (__attrNames t))
                else [];
            in f ".#hydraJobs.tests"
        ' \
        .#hydraJobs.tests \
        | jq -r '.[]'
)

nix build --no-link -L ${tests[@]}

check out current patchset of a cl by git alias

put this in a gitconfig that can configure aliases:

[alias]
	cocl = !\
	 ps=$(\
	   ssh $(git config remote.origin.gerriturl) \
	     gerrit query --format=json --current-patch-set $1 \
        | jq -sr .[0].currentPatchSet.ref \
	 ) && git fetch origin $ps && git checkout FETCH_HEAD && true

then run as git cocl <cl-number>. needs a git config remote.origin.gerriturl gerrit.lix.systems, or some other url that ssh can connect to. (could've extracted it from the remote url but we didn't want to do that much shell)

git stuff

git-revise

git-revise is a cool tool for splitting and shuffling commits in-memory without breaking your working tree. it's great.

It also has some broken stuff with respect to gerrit commit-msg hooks. However, this can be fixed (this is opt-in because some commit-msg hooks make unsound assumptions but the gerrit one should be fine):

# allow gerrit git hooks to run on git-revise
[revise "run-hooks"]
        commit-msg = true

Making git clean clean the stuff that isn't removed by make clean

If you don't want to use git clean -x to remove all git-ignored stuff, but want to remove things that are generated in Lix's build process but aren't removed by make clean, apply this patch: no-ignore-not-cleaned.patch
