Release 6 deletes the plans: the walk half of the holder, the controller port, the carry-over of the former module and the verbs times, what-if, release, stop and retire-history go; the table holds proposed, ready, rejected, merged, held and closed; the delivery's status and view name the source revision the merge moved.

# mesh-delivery-gate
|
|
|
|
The `mesh-delivery-gate` module of the mesh catalogue: the gate of design 47. It claims the seat `mesh-delivery`, whose
|
|
name stays (ADR 0437 §11), and takes over from the module `mesh-delivery` (ADR 0437 §3, ADR 0450 §6). Its buckets are
|
|
`mesh-delivery-gate_*`.
|
|
|
|
## Files it does not know
|
|
|
|
Each directory or archive this module declares says how it treats a file it did not write (ADR 0422, ADR 0416).
|
|
|
|
- `${dir:state}`: everything in it is the program's; the mesh moves nothing out (ADR 0422 §2).
|
|
|
|
## What it keeps (ADR 0539 §17)
|
|
|
|
The gate keeps the merge's states: proposed, ready, rejected, merged, held (a merge that reached the trunk without a passing
|
|
check) and closed. It asks the operator's Approve and merges once, moving `source.main`. It asks the controller nothing, follows
|
|
no plan event and derives nothing after the merge: whether a merged change reached the machines is the view's, from
|
|
`source.main`, the wants and the haves. The seat `mesh-delivery` keeps the verbs `deliveries`, `show`, `groups`, `checks`,
|
|
`table`, `stalled` (for a merge or a check past its bound), `recheck` and `close`; `times`, `what-if`, `release`, `stop` and
|
|
`retire-history` went with the plans, so the gate stays a bundle serving the seat. A delivery an earlier owner kept in a state that
|
|
is gone is read as the state it came to (merged, closed or proposed) when the gate starts.
|
|
|
|
## When a refused or rejected merge is said (ADR 0505 §4, §5)
|
|
|
|
`stalled` is what the controller raises as a condition for the operator. The gate's own list (`show`, `deliveries`)
|
|
names every refusal and rejection at once, and the pull request is told at once; only `stalled` waits:
|
|
|
|
- a merge refused because its trunk moved, whose check the gate asked again, is stalled only once that check answered and
|
|
the merge was refused again, or twice the repository's last check time passed (at least the setting
|
|
`refusal-stall-floor-minutes`, 10). Every other refusal is stalled at once.
|
|
- a delivery that needs its author's new head (its check failed after its Approve: a conflict, a failed check, a rejected
|
|
group) is stalled only once no new head came for the setting `author-new-head-minutes` (120). Its line says
|
|
`needs: new-head` and names its author: the branch, and the session a `Pushed-by: <who@node>` line in the pull
|
|
request's description names.
|
|
|
|
## The seat's hand-over
|
|
|
|
The gate took the seat `mesh-delivery` over from the module `mesh-delivery` (ADR 0449 §4, ADR 0450 §6, ADR 0454) and carried its
|
|
deliveries, groups and pull keys once; the carry, and the reading of the controller's assignments and the node-engine's have keys
|
|
that waited for it, went with release 6. `catalogue_test.go` keeps the catalogue to one claimant of the seat.
