  • PromoteResourceShareCreatedFromPolicy's featureSet state machine (CREATED_FROM_POLICY -> PROMOTING_TO_STANDARD -> STANDARD) is not modeled; every share created here is already STANDARD so this hasn't caused observed drift, but if CREATED_FROM_POLICY share creation is ever added, this needs revisiting.
  • permissionSummaryObject/permissionDetailObject emit a resourceRegionScope field that does not exist on the real ResourceSharePermissionSummary/ResourceSharePermissionDetail SDK types (harmless: the restjson1 deserializer ignores unrecognized fields, confirmed by reading deserializers.go). Not removed since it's a no-op field, not a bug -- kept as a deferred note rather than a gap since nothing is missing or wrong from the client's perspective.

func (h *Handler) Restore(ctx context.Context, data []byte) error

Restore implements persistence.Persistable by delegating to the backend.

func (*Handler) RouteMatcher 

func (h *Handler) RouteMatcher() service.Matcher

RouteMatcher returns a function that matches RAM API requests. All path-based matches are gated on the SigV4 service name to prevent routing conflicts with other services that share similar REST paths.

func (*Handler) Snapshot 

func (h *Handler) Snapshot(ctx context.Context) []byte

Snapshot implements persistence.Persistable by delegating to the backend.

type InMemoryBackend 

type InMemoryBackend struct {
	// contains filtered or unexported fields
}

InMemoryBackend is an in-memory store for AWS RAM resources.

func NewInMemoryBackend 

func NewInMemoryBackend(accountID, region string) *InMemoryBackend

NewInMemoryBackend creates a new in-memory RAM backend seeded with AWS-managed permissions.

func (*InMemoryBackend) AcceptResourceShareInvitation 

func (b *InMemoryBackend) AcceptResourceShareInvitation(
	invitationARN string,
) (*ResourceShareInvitation, error)

func (*InMemoryBackend) AddInvitationInternal 

func (b *InMemoryBackend) AddInvitationInternal(inv *ResourceShareInvitation)

AddInvitationInternal adds a pre-built invitation for testing or seeding.

func (*InMemoryBackend) AddPermissionInternal 

func (b *InMemoryBackend) AddPermissionInternal(p *Permission)

AddPermissionInternal inserts a permission directly, bypassing validation. Useful for seeding test state.

func (*InMemoryBackend) AddResourceShareInternal 

func (b *InMemoryBackend) AddResourceShareInternal(rs *ResourceShare)

AddResourceShareInternal inserts a resource share directly, bypassing validation. Useful for seeding test state.

func (*InMemoryBackend) AssociateResourceShare 

func (b *InMemoryBackend) AssociateResourceShare(
	shareARN string,
	principals, resourceARNs []string,
) ([]*ResourceShareAssociation, error)

AssociateResourceShare associates principals or resource ARNs with a resource share. Entities already ASSOCIATED are silently skipped (idempotent), matching AWS behavior. An entity with an existing DISASSOCIATED row (produced by a prior DisassociateResourceShare) is reactivated in place -- a real re-association, since AWS keeps a single row per (share, entity) pair and transitions its status rather than accumulating duplicates. Returns deep copies of the associations that changed state so callers cannot mutate backend state.

func (*InMemoryBackend) AssociateResourceSharePermission 

func (b *InMemoryBackend) AssociateResourceSharePermission(
	shareARN, permissionARN string,
	replace bool,
	permissionVersion *int32,
) error

AssociateResourceSharePermission associates a managed permission with a resource share.

func (*InMemoryBackend) AutoAssociateDefaultPermissions added in v1.2.0 

func (b *InMemoryBackend) AutoAssociateDefaultPermissions(shareARN string) error

AutoAssociateDefaultPermissions attaches the AWS-managed default permission for every resource type present in the share's active resource associations that does not already have an associated permission. Mirrors real AWS: CreateResourceShare and AssociateResourceShare automatically associate the default managed permission for each resource type included in the share when no explicit permission covers that type yet (CreateResourceShare's caller-supplied permissionArns skip this; the handler only calls this when none were supplied. AssociateResourceShare never accepts permissionArns at all, so real AWS always runs this step for it). Idempotent: calling it again after nothing changed is a no-op.

func (*InMemoryBackend) CreateInvitation 

func (b *InMemoryBackend) CreateInvitation(
	shareARN, shareNm, senderAcctID, receiverAcctID string,
) *ResourceShareInvitation

CreateInvitation creates a pending invitation for a resource share. This is a helper for the mock that mirrors what AWS does when AssociateResourceShare is called with principals.

func (*InMemoryBackend) CreatePermission 

func (b *InMemoryBackend) CreatePermission(
	name, resourceType, policyTemplate string,
	tags map[string]string,
) (*Permission, error)

CreatePermission creates a new customer-managed RAM permission.

func (*InMemoryBackend) CreatePermissionVersion 

func (b *InMemoryBackend) CreatePermissionVersion(
	permissionARN, policyTemplate string,
) (*Permission, error)

CreatePermissionVersion creates a new version of an existing customer-managed RAM permission.

func (*InMemoryBackend) CreateResourceShare 

func (b *InMemoryBackend) CreateResourceShare(
	name string,
	allowExternalPrincipals bool,
	tags map[string]string,
	principals, resourceARNs []string,
) (*ResourceShare, error)

CreateResourceShare creates a new resource share.

func (*InMemoryBackend) DeletePermission 

func (b *InMemoryBackend) DeletePermission(permissionARN string) error

DeletePermission soft-deletes a customer-managed RAM permission and removes it from all shares. AWS-managed permissions cannot be deleted.

func (*InMemoryBackend) DeletePermissionVersion 

func (b *InMemoryBackend) DeletePermissionVersion(
	permissionARN string,
	permissionVersion int32,
) error

DeletePermissionVersion deletes a specific version of a customer-managed RAM permission. The default version cannot be deleted. If the latest version is deleted, LatestVersion is updated to the next-highest remaining version.

func (*InMemoryBackend) DeleteResourceShare 

func (b *InMemoryBackend) DeleteResourceShare(shareARN string) error

DeleteResourceShare deletes a resource share and removes it from the store. Associations for the share are disassociated before the share is removed so that ListResources / ListPrincipals no longer return them.

func (*InMemoryBackend) DisassociateResourceShare 

func (b *InMemoryBackend) DisassociateResourceShare(
	shareARN string,
	principals, resourceARNs []string,
) ([]*ResourceShareAssociation, error)

DisassociateResourceShare marks principals or resource ARNs on a resource share as DISASSOCIATED. Rows are kept in place (soft-deleted), matching the same pattern DeleteResourceShare uses for every association on a deleted share -- this lets GetResourceShareAssociations(associationStatus=DISASSOCIATED) see the history, and lets a later AssociateResourceShare reactivate the row instead of accumulating duplicates (see reactivateOrCreateLocked). Only currently-ASSOCIATED rows are affected; disassociating an entity that is not currently associated is a no-op for that entity.

func (*InMemoryBackend) DisassociateResourceSharePermission 

func (b *InMemoryBackend) DisassociateResourceSharePermission(
	shareARN, permissionARN string,
) error

DisassociateResourceSharePermission removes a managed permission from a resource share. Real AWS refuses the request while any resource of the permission's resource type is still actively attached to the share, per the documented rule: you can remove a managed permission from a resource share only if there are currently no resources of the relevant resource type currently attached to the resource share.

func (*InMemoryBackend) GetPermission 

func (b *InMemoryBackend) GetPermission(
	permissionARN string,
	permissionVersion *int32,
) (*Permission, *PermissionVersion, error)

GetPermission returns the details of a RAM permission, optionally at a specific version.

func (*InMemoryBackend) GetResourcePolicies 

func (b *InMemoryBackend) GetResourcePolicies(resourceARNs []string) []string

GetResourcePolicies returns resource-based policy documents for shared resources. Only ARNs that are actively associated with a resource share receive a policy entry; ARNs not in any share are omitted, matching real AWS behaviour.

func (*InMemoryBackend) GetResourceShare 

func (b *InMemoryBackend) GetResourceShare(shareARN string) (*ResourceShare, error)

GetResourceShare returns a resource share by ARN.

func (*InMemoryBackend) GetResourceShareAssociations 

func (b *InMemoryBackend) GetResourceShareAssociations(
	associationType string,
	shareARNs []string,
) []*ResourceShareAssociation

GetResourceShareAssociations returns associations for the given resource share ARNs and type.

func (*InMemoryBackend) GetResourceShareInvitations 

func (b *InMemoryBackend) GetResourceShareInvitations(
	invitationARNs, shareARNs []string,
) []*ResourceShareInvitation

GetResourceShareInvitations returns invitations filtered by ARN or resource share ARN, sorted by creation time (oldest first) for deterministic output.

func (*InMemoryBackend) ListPendingInvitationResources 

func (b *InMemoryBackend) ListPendingInvitationResources(
	invitationARN string,
) ([]*ResourceShareAssociation, error)

ListPendingInvitationResources returns the resource associations for the resource share associated with the given invitation, filtered to resources that are in an active state.

func (*InMemoryBackend) ListPermissionAssociations 

func (b *InMemoryBackend) ListPermissionAssociations(
	permissionARN string,
) []SharePermissionAssociation

ListPermissionAssociations returns all share-permission associations filtered optionally by permissionARN, sorted by share ARN + permission ARN.

func (*InMemoryBackend) ListPermissionVersions 

func (b *InMemoryBackend) ListPermissionVersions(
	permissionARN string,
) ([]*PermissionVersion, error)

ListPermissionVersions returns all versions of a permission, sorted ascending by version number.

func (*InMemoryBackend) ListPermissions 

func (b *InMemoryBackend) ListPermissions(resourceType string) []*Permission

ListPermissions returns all non-deleted customer-managed permissions, optionally filtered by resource type, sorted by ARN.

func (*InMemoryBackend) ListPrincipals 

func (b *InMemoryBackend) ListPrincipals(
	resourceOwner, shareARN string,
) []*ResourceShareAssociation

ListPrincipals returns principal associations for shares, filtered by resourceOwner ("SELF" or "OTHER-ACCOUNTS") and share ARN. Sorted by associated entity.

func (*InMemoryBackend) ListReplacePermissionAssociationsWork added in v1.2.0 

func (b *InMemoryBackend) ListReplacePermissionAssociationsWork(
	workIDs []string, status string,
) []*ReplacePermissionAssociationsWork

ListReplacePermissionAssociationsWork returns recorded ReplacePermissionAssociations background work items, optionally filtered by work ID and/or status, sorted newest-first.

func (*InMemoryBackend) ListResourceSharePermissions 

func (b *InMemoryBackend) ListResourceSharePermissions(shareARN string) []*ResourceSharePermissionDetail

ListResourceSharePermissions returns the permissions associated with a resource share, each paired with the version actually associated with that share (which may differ from the permission's current default version), sorted by ARN for deterministic output.

func (*InMemoryBackend) ListResourceShares 

func (b *InMemoryBackend) ListResourceShares(resourceOwner, status string) []*ResourceShare

ListResourceShares returns resource shares matching the given owner and optional status filter. resourceOwner must be "SELF" or "OTHER-ACCOUNTS".

  • "SELF": shares owned by this account (not deleted, optionally filtered by status).
  • "OTHER-ACCOUNTS": shares owned by another account where this account is a PRINCIPAL.

Pass status="" to return all matching shares, or e.g. "ACTIVE" to filter by status.

func (*InMemoryBackend) ListResources 

func (b *InMemoryBackend) ListResources(
	resourceOwner, shareARN, resourceType string,
) []*ResourceShareAssociation

ListResources returns resources (resource-type associations) for shares, filtered by resourceOwner ("SELF" or "OTHER-ACCOUNTS"), share ARN, and resource type.

func (*InMemoryBackend) ListTagsForResource 

func (b *InMemoryBackend) ListTagsForResource(shareARN string) (map[string]string, error)

ListTagsForResource returns tags for a resource share identified by ARN.

func (*InMemoryBackend) PromotePermissionCreatedFromPolicy 

func (b *InMemoryBackend) PromotePermissionCreatedFromPolicy(
	permissionARN string, name string,
) (*Permission, error)

PromotePermissionCreatedFromPolicy promotes a CREATED_FROM_POLICY permission to a CUSTOMER_MANAGED permission with the given name.

func (*InMemoryBackend) PromoteResourceShareCreatedFromPolicy 

func (b *InMemoryBackend) PromoteResourceShareCreatedFromPolicy(
	shareARN string,
) (*ResourceShare, error)

PromoteResourceShareCreatedFromPolicy promotes a resource share to standard feature set. In this mock, it simply returns the existing share unchanged.

func (*InMemoryBackend) Region 

func (b *InMemoryBackend) Region() string

Region returns the AWS region this backend is configured for.

func (*InMemoryBackend) RejectResourceShareInvitation 

func (b *InMemoryBackend) RejectResourceShareInvitation(

func (*InMemoryBackend) ReplacePermissionAssociations 

func (b *InMemoryBackend) ReplacePermissionAssociations(
	fromPermissionARN, toPermissionARN string,
	fromPermissionVersion *int32,
) (*ReplacePermissionAssociationsWork, error)

ReplacePermissionAssociations replaces all associations using fromPermissionARN with toPermissionARN across all resource shares. If fromPermissionVersion is non-nil, only shares currently pinned to that specific version are replaced (matching AWS's documented per-version filtering); otherwise every share using fromPermissionARN at any version is replaced. The replacement always associates toPermissionARN's current default version, matching real AWS.

This mock performs the swap synchronously, so the returned work item's Status is always the terminal COMPLETED state -- there is no separate async completion step to model. Returns the work item for ListReplacePermissionAssociationsWork lookups.

func (*InMemoryBackend) Reset 

func (b *InMemoryBackend) Reset()

Reset clears all in-memory state from the backend and re-seeds built-in permissions. It is used by the POST /_gopherstack/reset endpoint for CI pipelines and rapid local development.

func (*InMemoryBackend) Restore 

func (b *InMemoryBackend) Restore(ctx context.Context, data []byte) error

Restore loads backend state from a JSON snapshot. It implements persistence.Persistable.

func (*InMemoryBackend) SetDefaultPermissionVersion 

func (b *InMemoryBackend) SetDefaultPermissionVersion(
	permissionARN string,
	version int32,
) (*Permission, error)

SetDefaultPermissionVersion updates the default version of a customer-managed permission.

func (*InMemoryBackend) Snapshot 

func (b *InMemoryBackend) Snapshot(ctx context.Context) []byte

Snapshot serialises the backend state to JSON. It implements persistence.Persistable.

func (*InMemoryBackend) TagResource 

func (b *InMemoryBackend) TagResource(shareARN string, kv map[string]string) error

TagResource adds or updates tags on a resource share identified by ARN.

func (*InMemoryBackend) UntagResource

) (*ResourceShare, error)

UpdateResourceShare updates an existing resource share. If name is changed, all matching associations are updated to reflect the new name.

type Permission 

type Permission struct {
	CreationTime          time.Time                    `json:"creationTime"`
	LastUpdatedTime       time.Time                    `json:"lastUpdatedTime"`

type ReplacePermissionAssociationsWork added in v1.2.0 

type ReplacePermissionAssociationsWork struct {
	CreationTime          time.Time
	LastUpdatedTime       time.Time
	ID                    string
	FromPermissionARN     string
	ToPermissionARN       string
	Status                string
	StatusMessage         string
	FromPermissionVersion int32
	ToPermissionVersion   int32
}

ReplacePermissionAssociationsWork tracks the background task created by a ReplacePermissionAssociations call, retrievable via ListReplacePermissionAssociationsWork. This mock performs the underlying association swap synchronously, so a work item's Status is always terminal (COMPLETED) by the time it is stored -- there is no separate async completion step to model.

type ResourceShare 

type ResourceShare struct {
	LastUpdatedTime         time.Time         `json:"lastUpdatedTime"`
	CreationTime            time.Time         `json:"creationTime"`

type ResourceSharePermissionDetail 

type ResourceSharePermissionDetail struct {
	Permission *Permission
	Version    int32
}

ResourceSharePermissionDetail pairs a managed permission with the specific version that is associated with a particular resource share. AWS tracks the associated version per (share, permission) pair -- AssociateResourceSharePermission can pin a non-default version -- so this must be reported per share rather than assumed to be the permission's current default version.

type SharePermissionAssociation 

type SharePermissionAssociation struct {
	ShareARN      string
	PermissionARN string
	Version       int32
}

SharePermissionAssociation represents a share-permission link for ListPermissionAssociations.
