A mesh-wide provision a machine could answer itself was bound to the local provider, with the
seat's holder and any pin consulted only for a provider on another machine. With every machine
still running its own resolver, each bound its resolver configuration to itself while the mesh's
one resolver was held and pinned elsewhere.
The catalogue moves daemon.json's live-restore and the reload from resolv-conf to the docker
module, so no module writes another software's configuration. The test composes docker beside
the resolver modules and refuses resolv-conf writing the runtime's file.
A registered replay asked now outranked newer asks of its module, and a plan
took any later outcome as its answer. A replay is now refused while the module
is asked anywhere, a plan module asked under an id is answered by that id
alone, and a rebuild of a commit asks what the module follows. An ask handed
back after a restart no longer reads as dead; a cancel that meets a start is
withdrawn; pause holds for an ask fetched as it lands; kill removes containers
before and after the build ends and says whether its outcome went out; a
holder may say only its own machine is paused.
The holder's verbs were served and found by nothing; it now answers discovery
with its machine's four, as a runtime announces a seat's verb, so the console
finds <node>/node-build-agent.kill. A cancel publishes no outcome, so a build
waited for also looks at the cancelled set. A plan that stopped at its first
machine is retried by sending that machine the module again, unless a newer
plan holds it.
Nothing showed what waited for a build machine, and an ask could not be
dropped without leaving the plan that made it waiting for ever. New verbs:
queue, cancel, clear, rebuild, replay, kill, pause, resume, and plans retry.
Every ask a person drops is recorded failed through the same take-in as a
failed build; a plan keeps the id it asked each module under and matches
its outcome by it. replay is a dry run unless registered, and registering
an older commit than one registered since needs --older (hq issue 207).
A plan waiting on a seat paused on every holder says so and is not late;
a failed plan can be retried, and a rebuild joins the plan holding the
module instead of running beside it.
A queued ask could only be waited out and a running build only ended by
stopping the machine, which redelivered it elsewhere. The holder now serves
current, kill, pause and resume on its own machine's subjects; a kill ends
the build's process group and labelled containers and settles the ask as
failed, killed by hand; pause is kept in the workspace across a restart and
said on the bus. The controller writes cancelled ids to a cancelled set the
holder reads on taking an ask, closing the race a delete alone leaves.
With one machine first a module is sent twice, and the tier gate asked every
machine for a report after the second send: the first machine's report, made
between the two, read as stale and the plan waited for ever (hq issue 256).
Also round a plan's wait to the second, not the minute, so it is not 0s.
A first machine that does not report within the bound now stops the
module's rollout, naming it. The first machine is the first by name heard
from lately; reports are judged by what the store says was last sent. A
plan that ends says what it built and never sent, and a failed send's
error is kept in the plan's note.
Grants first could hold back the very declaration that lets the controller
issue them. The holder now goes first, then buckets and memberships, then
the rest; a membership that fails holds back only its own machine, and an
announcement whose send stopped at its grants is asked again. Whether the
holder must go first is read from a digest of the user list it was last
sent, not its whole declaration. Migration renumbered to 0058.
The catalogue's upgrade announcement sent every machine one after another
without waiting for any to apply, beside the plan that now sends one
machine first. A module an open plan has not finished sending is the
plan's to roll out.
A merge planned without looking at open plans, so two plans worked the
same modules and a stuck plan stayed open for ever. The newer plan folds
in what older plans of the same repository and branch had not built or
sent, and closes them as superseded. A person can close a stuck plan by
id with `plans close <id>`.
A plan sent every machine running a module at once, ignoring the module's
upgrade policy. Unless the policy says together, the first machine by name
is sent, recorded in the plan, and the rest follow only once its report
after the send says it applied; a failed first machine stops the plan.
A module's new state reached every machine before the permissions to use
it, which came only with a later push. Memberships and buckets now go
before declarations, the machine holding mesh-broker goes first when its
user list must change, and a grant that fails sends nothing and is an
error so the rollout is retried.
A merge adding a module the mesh has not registered rebuilt every module
built from the repository. A path under a directory known to hold modules
belongs to that module when its module.json is among the changed files.
The store's garbage-collect marks only from manifests, and archives were
published as bare blobs, so the first real collection would delete every
archive the mesh keeps. PublishArchive now puts a deterministic OCI holder
manifest (empty config, one layer) beside each archive; the sweep holds every
kept archive before it lets anything go, which backfills existing bare blobs,
and lets go of an archive holder-first. A forgotten module no longer keeps its
five recent builds (ADR 0189). `collection [--json]` reports kept archives
held/unheld and what may be let go, so the dry run can be lifted on evidence.
The postgres-backed test still expected a module that declares no broker
secret to be a bus user, and failed on main since #270; it skips without a
database, so the change's own run did not see it.
A consumer made with the server's default replays everything a stream that
keeps history holds: the controller's EVENTS consumer, re-made that way,
replayed a week of merges and builds one at a time and held every new one
behind them. FromNow makes it start at the end; broker consumer-reset
re-makes a stuck one from now, refusing a work queue. hq issue 244.
ADR 0214 / to-be 43: a node seat whose holder keeps nightly restore points of what every module on
the machine declares. A contribution of kind backup may name its module's own directories, filled
per module when placed. The catalogue check refuses a store provider that contributes no backup;
parsing does not, so the providers already running stay readable.
A dry run of an unreviewed branch was heard by the daemon like any build, registered, and its
definition reached a machine (novox/hq issue 240). The mark now travels with the build and the
daemon records, registers and plans nothing for it.
Every assigned module was composed as a bus user, though only one declaring
a broker secret can ever be issued an account; the rest were named on every
status, plan and push as credentials never minted (137 now), burying the
real gaps. Their durable consumers are now derived from what the runtime
carries, so nothing they hear changes. The composed file is unchanged:
those users had no password and were already left out. Fixes hq issue 195.
- mesh-dns-resolver: a mesh seat delivering wildcard-resolution, so every node's resolver
configuration resolves to its one holder; node-dns-resolver kept until nothing claims it.
- ${bound:<provision>:address}: the providing machine's private address, for the one consumer
that cannot use a name — a machine's resolver configuration.
- zone: a module declares the zone it answers and the listen that answers it; the controller
settles it per node, refuses duplicates and shadowing, and hands the resolver .Zones to forward.
- node-hosts-file: a node seat whose holder owns /etc/hosts, with entries/add/remove.
The resolver tests follow the catalogue: no runtime dns (containers copy the machine's resolvers),
live-restore held by resolv-conf, resolv.conf naming the resolver by address then a public one.
Each contribution grain was a manifest field and a renderer of its own; a module now contributes
to any seat with a kind that seat receives, the holder places it with
${contribution:<seat>:<kind>}, and the contribution depends on the seat. node-hotkeys is the
first new seat to receive (triggers); the display session receives window-manager config.
A module that needs code after waking wrote into the service manager's sleep units; it now
contributes shell code for a named moment, which derives a dependency on node-power.
The environment and shell contributions were written nowhere on a node without their holder;
they now derive a dependency on node-environment, node-login-shell or node-display-server, met
and refused as ADR 0207's are. Two modules declaring one package, path or unit made the node
unresolvable after the assignment was recorded; that is refused first now, because no later
assignment can complete it.
status reported no unmet dependency on any node once systemd, pacman and docker
were assigned to all four (to-be 42), which is the condition ADR 0207 set for the
switch. A dependency no catalogue module could meet stays a report before and
after the switch, as assign already said it: there is no remedy to name.
assign and unassign say only what they changed on their node; push <node>
lists that node's, push to many counts each and points at status. The
once-per-change log is the serving controller's alone: a one-shot command
starts with no memory, so it logged every node on every call.
