mesh-grants' sealed grants and the controller's merge record each met "message size exceeds maximum" (JetStream
10054) only after the put, and a writer that retries looped on a value that can never land; an update over the
limit was even answered as a revision mismatch, which every compare-and-set writer retries.
Quick fix: cap the two values in their modules. Thorough fix, chosen because the kind was met twice and every
module writes through the SDK: the package kvlimit checks a value against its bucket's largest message (read from
its stream and kept) before the put, naming the bucket, the key, the size and the limit, and turns the bus's own
refusal into the same *TooLarge (errors.Is kvlimit.ErrTooLarge), so no writer retries it. The SDK's own writers
use it: process.State (Put, Create, CreateTTL, Update), process.AwaitedBucket, the runtime state of a bundle
(stdio KeptState, against the module state's 256 KiB) and mesh-hand-compose. A value that can outgrow its bucket
is split over keys or kept in the object store with its name in the key.
PlansHeld holds a module whose build cannot be taken in or whose plan refuses, by composeEach's rule, and composes
every other module's plan; sealedFor gives a file the stand-in its own secret's file has (baserow on ace); shipsABundle
reads a built manifest's Bundles (nats on novox).
mesh/check being carried to af66ccb8335a on 1d9de5dbb63b | from 42988a734b3d | novox/mesh-sdk#137 in group fix/provisioner-reads-every-plan
The client V3 watches the seat's plans whole to bind a provider's consumers (ADR 0373); the grant gave each machine
only its own keys, so its watch was refused and no files were placed. Quick fix, chosen in a recovery: plans join
the buckets a client reads whole (references, never secret values). Thorough fix, queued: the client fills consumers
from the seat's provision keys (ADR 0570 clause 3) and plans go back to its own machine's keys.
mesh/check checking 6e7820395952 on 42988a734b3d | novox/mesh-sdk#136 in group fix/runner-carries-no-engine-state
Second meeting of the engine-state-in-runner kind (mesh-host_acts this
morning, mesh-host_health now); thorough: the runner never carries the
engine module. One predicate, Composed, keeps the engine out of the
placed loop (no user, no process, nothing carried); CarriedByRunner is
the one test of what the runner carries. The engine's grants stay the
node account's, its state created through Records.Engine.
mesh/check checking 9379e9a96ad4 on d0625eea3d11 | novox/mesh-sdk#135 in group fix/credential-forms-one-list
Second meeting of the credential-form list kind: the provisioner client's
own copy lacked "none" and refused every plan naming it, as the
controller's had before. Thorough: one list in mesh-sdk,
catalogue.CredentialForms and IsCredentialForm; provisions' forms are now
the catalogue's constants.
mesh/check checking 83cf97b690f5 on 0c99e847a2ae | novox/mesh-sdk#134 in group fix/memberships-shape
The grants part's old build wrote its wrapper for every membership, a held-back one too, with the unpublished
composition inside; the new part never rewrites such a key, so the decoder took the held-back membership as given.
It now reads a wrapper only when its published says published or unchanged. The codec's rows join the round-trip
test (mesh-sdk is over its unit budget). Review round 1 of issue 774's fix.
The grants part wrote its own wrapper into mesh-grants_memberships while the tool runner read the value as a bare
membership: novox's tool runner served no tool. EncodeGrantsMembership writes the bare membership;
DecodeGrantsMembership and BareGrantsMembership read it, still read the old wrapper for the transition, and refuse a
value naming no node or module instead of answering an empty membership.
Issue 774 (the bus login list, L3). Quick fix: write the bare membership in the grants part alone. Thorough, chosen:
one codec in mesh-sdk both sides use, because a hand-built test fixture agreed with the mistake and hid it.
NodeHealth.Root: each such account's verdict (healthy, unhealthy with its way to root, unknown while the setuid search
runs), the module and resource declaring it. NodeHealth.Contract: the engine's statement contract, so a reader tells an
engine older than the judging. Test: a row in TestTheControlRecordsReadTheirWritersValues, read back byte-equal.
NetworkPart.Targets: the hub's machine for "hub", the machine whose tunnel address is each resolver's; empty where the
part is the machine's own. Filled by the node-engine from its tunnel's peers. Test: a row in
TestTheControlRecordsReadTheirWritersValues, read back byte-equal.
