The Bundle structure is immutable and will always be replaced in its entirety, with new backing memory.

type BundleSource

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

BundleSource stores a reference to the current configuration bundle It also provides a method to update this bundle. The assorted methods largely pass through to the underlying bundle, but do so through an atomic pointer so that gross go-routine reads are not vulnerable to out-of-order execution memory type bugs.

func NewBundleSource

func NewBundleSource(bundle *Bundle, callbacks ...func(*Bundle)) *BundleSource

NewBundleSource creates a new BundleSource with an initial Bundle value The callbacks will be invoked whenever the Update method is called for the BundleSource. Note, these callbacks are called immediately before this function returns.

func (bs *BundleSource) PolicyManager() policies.Manager

PolicyManager returns the policy manager constructed for this config

func (*BundleSource) StableBundle

func (bs *BundleSource) StableBundle() *Bundle

StableBundle returns a pointer to a stable Bundle. It is stable because calls to its assorted methods will always return the same result, as the underlying data structures are immutable. For instance, calling BundleSource.Orderer() and BundleSource.MSPManager() to get first the list of orderer orgs, then querying the MSP for those org definitions could result in a bug because an update might replace the underlying Bundle in between. Therefore, for operations which require consistency between the Bundle calls, the caller should first retrieve a StableBundle, then operate on it.

func (bs *BundleSource) Update(newBundle *Bundle)

Update sets a new bundle as the bundle source and calls any registered callbacks

func (*BundleSource) ValidateNew

func (bs *BundleSource) ValidateNew(resources Resources) error
