func (*Repository) UpdateCatalog 

func (r *Repository) UpdateCatalog(ctx context.Context, c *HostCatalog, version uint32, fieldMask []string, _ ...Option) (*HostCatalog, *hostplugin.Plugin, int, error)

UpdateCatalog updates the repository entry for c.PublicId with the values in c for the fields listed in fieldMask. It returns a new HostCatalog containing the updated values and a count of the number of records updated. c is not changed.

c must contain a valid PublicId. c.Name, c.Description, and c.Attributes can be updated; if c.Secrets is present, its contents are sent to the plugin (along with any other changes, see below) before the update is sent to the database.

An attribute of c will be set to NULL in the database if the attribute in c is the zero value and it is included in fieldMask. Note that this does not apply to c.Attributes - a null c.Attributes is a no-op for modifications. Rather, if fields need to be reset, its field in c.Attributes should individually set to null.

Updates are sent to OnUpdateCatalog with a full copy of both the current catalog, and the state of the new catalog should it be updated, along with any secrets included in the new request. This request may alter the returned persisted state. Update of the record in the database is aborted if this call fails.

func (*Repository) UpdateSet 

func (r *Repository) UpdateSet(ctx context.Context, scopeId string, s *HostSet, version uint32, fieldMask []string, opt ...Option) (*HostSet, []*Host, *hostplugin.Plugin, int, error)

UpdateSet updates the repository for host set entry s with the values populated, for the fields listed in fieldMask. It returns a new HostSet containing the updated values, the hosts in the set, and a count of the number of records updated. s is not changed.

s must contain a valid PublicId and CatalogId. Name, Description, Attributes, and PreferredEndpoints can be updated. Name must be unique among all sets associated with a single catalog.

An attribute of s will be set to NULL in the database if the attribute in s is the zero value and it is included in fieldMask. Note that this does not apply to s.Attributes - a null s.Attributes is a no-op for modifications. Rather, if fields need to be reset, its field in c.Attributes should individually set to null.

Updates are sent to OnUpdateSet with a full copy of both the current set, the state of the new set should it be updated, along with its parent host catalog and persisted state (can include secrets). This is a stateless call and does not affect the final record written, but some plugins may perform some actions on this call. Update of the record in the database is aborted if this call fails.
