-# gerrit-queue
-
-This daemon automatically rebases and submits changesets from a Gerrit
-instance, ensuring they still pass CI.
-
-In a usual gerrit setup with a linear master history, different developers
-await CI feedback on a rebased changeset, then one clicks submit, and
-effectively makes everybody else rebase again. `gerrit-queue` is meant to
-remove these races to master.
-
-Developers can set the `Autosubmit` label to `+1` on all changesets in a series,
-and if all preconditions on are met ("submittable" in gerrit speech, this
-usually means passing CI and passing Code Review), `gerrit-queue` takes care of
-rebasing and submitting it to master
-
-## How it works
-Gerrit only knows about Changesets (and some relations to other changesets),
-but usually developers think in terms of multiple changesets.
-
-### Fetching changesets
-`gerrit-queue` fetches all changesets from gerrit, and tries to identify these
-chains of changesets. We call them `Series`. All changesets need to have strict
-parent/child relationships to be detected (so if only half of the stack gets
-rebased by the Gerrit Web interface, these are considered individual series.
-
-Series are sorted by the number of changesets in them. This ensures longer
-series are merged faster, and less rebases are triggered. In the future, this
-might be extended to other metrics.
-
-### Submitting changesets
-The submitqueue has a Trigger() function, which gets periodically executed.
-
-It can keep a reference to one single serie across multiple runs. This is
-necessary if it previously rebased one serie to current HEAD and needs to wait
-some time until CI feedback is there. If it wouldn't keep that state, it would
-pick another series (with +1 from CI) and trigger a rebase on that one, so
-depending on CI run times and trigger intervals, if not keepig this information
-it'd end up rebasing all unrebased changesets on the same HEAD, and then just
-pick one, instead of waiting for the one to finish.
-
-The Trigger() function first instructs the gerrit client to fetch changesets
-and assemble series.
-If there is a `wipSerie` from a previous run, we check if it can still be found
-in the newly assembled list of series (it still needs to contain the same
-number of series. Commit IDs may differ, because the code doesn't reassemble a
-`wipSerie` after scheduling a rebase.
-If the `wipSerie` could be refreshed, we update the pointer with the newly
-assembled series. If we couldn't find it, we drop it.
-
-Now, we enter the main for loop. The first half of the loop checks various
-conditions of the current `wipSerie`, and if successful, does the submit
-("Submit phase"), the second half will pick a suitable new `wipSerie`, and
-potentially do a rebase ("Pick phase").
-
-#### Submit phase
-We check if there is an existing `wipSerie`. If there isn't, we immediately go to
-the "pick" phase.
-
-The `wipSerie` still needs to be rebased on `HEAD` (otherwise, the submit queue
-advanced outside of gerrit), and should not fail CI (logical merge conflict) -
-otherwise we discard it, and continue with the picking phase.
-
-If the `wipSerie` still contains a changeset awaiting CI feedback, we `return`
-from the `Trigger()` function (and go back to sleep).
-
-If the changeset is "submittable" in gerrit speech, and has the necessary
-submit queue tag set, we submit it.
-
-#### Pick phase
-The pick phase finds a new `wipSerie`. It'll first try to find one that already
-is rebased on the current `HEAD` (so the loop can just continue, and the next
-submit phase simply submit), and otherwise fall back to a not-yet-rebased
-serie. Because the rebase mandates waiting for CI, the code `return`s the
-`Trigger()` function, so it'll be called again after waiting some time.
