From ea3bfa5e6e507406211f215f231e5791a04bcfc3 Mon Sep 17 00:00:00 2001 From: jochen Date: Tue, 27 Oct 2026 21:02:49 +0100 Subject: [PATCH] Grant every node the keys a provider elsewhere serves from, and give the composition check frombus's new reads, pinning mesh-sdk cebc651 (issue 1126) mesh-grants declares each module's served settings (catalogue.ServedSettings), so the user list grants every other node's agent those keys of mesh-config_resolved alone: shanks then settles what novox's mailu serves. The assigner's check of every node reads no build, archive or served value: it composes as before. --- .../cmd/mesh-delivery-assigner/world.go | 14 ++++++++++++++ modules/mesh-delivery-assigner/go.mod | 2 +- modules/mesh-delivery-assigner/go.sum | 2 ++ modules/mesh-grants/go.mod | 2 +- modules/mesh-grants/go.sum | 2 ++ modules/mesh-grants/grants_test.go | 13 +++++++++++++ modules/mesh-grants/internal/grants/records.go | 2 ++ 7 files changed, 35 insertions(+), 2 deletions(-) diff --git a/modules/mesh-delivery-assigner/cmd/mesh-delivery-assigner/world.go b/modules/mesh-delivery-assigner/cmd/mesh-delivery-assigner/world.go index f0d2949..6ebbe6a 100644 --- a/modules/mesh-delivery-assigner/cmd/mesh-delivery-assigner/world.go +++ b/modules/mesh-delivery-assigner/cmd/mesh-delivery-assigner/world.go @@ -368,6 +368,20 @@ func (worldReader) Credentials(context.Context, string, []compose.CredentialKey, return nil, nil, nil } +// Build, Archive and Served are read only for a node composing itself (frombus.Scope without Every): the check of every +// node composes from the manifests the indexer read, reads no build and no archive, and reads no config value. +func (worldReader) Build(context.Context, string, string) (*delivery.BuilderBuild, error) { + return nil, nil +} + +func (worldReader) Archive(_ context.Context, url, _ string) ([]byte, error) { + return nil, fmt.Errorf("the composition check reads no archive (%s)", url) +} + +func (worldReader) Served(context.Context, string, string, []string) (map[string]any, error) { + return nil, nil +} + // change is a candidate's change for the composition check, or why the composition waits for it. func (w *world) change(ctx context.Context, manifests getter, c delivery.Candidate, trunk map[string]delivery.Module) (assign.Change, string) { ch := assign.Change{Group: c.Group, Heads: c.HeadsHash, Manifests: map[string]catalogue.Manifest{}, Unreadable: map[string]string{}, diff --git a/modules/mesh-delivery-assigner/go.mod b/modules/mesh-delivery-assigner/go.mod index 73e5df7..5685a33 100644 --- a/modules/mesh-delivery-assigner/go.mod +++ b/modules/mesh-delivery-assigner/go.mod @@ -3,7 +3,7 @@ module mesh-delivery-assigner go 1.26.0 require ( -
