Overview ¶
Package core implements the IpfsNode object and related methods.
Packages underneath core/ provide a (relatively) stable, low-level API to carry out most IPFS-related tasks. For more details on the other interfaces and how core/... fits into the bigger IPFS picture, see:

Constants ¶
const IpnsValidatorTag = "ipns"
Variables ¶
var DefaultBootstrapConfig = BootstrapConfig{
MinPeerThreshold: 4,
Period: 30 * time.Second,
ConnectionTimeout: (30 * time.Second) / 3,
}
DefaultBootstrapConfig specifies default sane parameters for bootstrapping.
var ErrNoNamesys = errors.New(
"core/resolve: no Namesys on IpfsNode - can't resolve ipns entry")
ErrNoNamesys is an explicit error for when an IPFS node doesn't (yet) have a name system
var ErrNotEnoughBootstrapPeers = errors.New("not enough bootstrap peers to bootstrap")
ErrNotEnoughBootstrapPeers signals that we do not have enough bootstrap peers to bootstrap correctly.
Functions ¶
func Bootstrap ¶
func Bootstrap(n *IpfsNode, cfg BootstrapConfig) (io.Closer, error)
Bootstrap kicks off IpfsNode bootstrapping. This function will periodically check the number of open connections and -- if there are too few -- initiate connections to well-known bootstrap peers. It also kicks off subsystem bootstrapping (i.e. routing).
func Resolve ¶ added in v0.3.2
func Resolve(ctx context.Context, nsys namesys.NameSystem, r *path.Resolver, p path.Path) (node.Node, error)
Resolve resolves the given path by parsing out protocol-specific entries (e.g. /ipns/<node-key>) and then going through the /ipfs/ entries and returning the final node.
func ResolveToCid ¶ added in v0.4.5
func ResolveToCid(ctx context.Context, n *IpfsNode, p path.Path) (*cid.Cid, error)
ResolveToKey resolves a path to a key.
It first checks if the path is already in the form of just a key (<key> or /ipfs/<key>) and returns immediately if so. Otherwise, it falls back onto Resolve to perform resolution of the dagnode being referenced.
Types ¶
type BootstrapConfig ¶
type BootstrapConfig struct {
// MinPeerThreshold governs whether to bootstrap more connections. If the
// node has less open connections than this number, it will open connections
// to the bootstrap nodes. From there, the routing system should be able
// to use the connections to the bootstrap nodes to connect to even more
// peers. Routing systems like the IpfsDHT do so in their own Bootstrap
// process, which issues random queries to find more peers.
MinPeerThreshold int
// Period governs the periodic interval at which the node will
// attempt to bootstrap. The bootstrap process is not very expensive, so
// this threshold can afford to be small (<=30s).
Period time.Duration
// ConnectionTimeout determines how long to wait for a bootstrap
// connection attempt before cancelling it.
ConnectionTimeout time.Duration
// BootstrapPeers is a function that returns a set of bootstrap peers
// for the bootstrap process to use. This makes it possible for clients
// to control the peers the process uses at any moment.
BootstrapPeers func() []pstore.PeerInfo
}
BootstrapConfig specifies parameters used in an IpfsNode's network bootstrapping process.
func BootstrapConfigWithPeers ¶
func BootstrapConfigWithPeers(pis []pstore.PeerInfo) BootstrapConfig
type BuildCfg ¶ added in v0.3.8
type BuildCfg struct {
// If online is set, the node will have networking enabled
Online bool
// ExtraOpts is a map of extra options used to configure the ipfs nodes creation
ExtraOpts map[string]bool
// If permament then node should run more expensive processes
// that will improve performance in long run
Permament bool
// If NilRepo is set, a repo backed by a nil datastore will be constructed
NilRepo bool
Routing RoutingOption
Host HostOption
Repo repo.Repo
}
type DiscoveryOption ¶ added in v0.3.2
type DiscoveryOption func(context.Context, p2phost.Host) (discovery.Service, error)
type HostOption ¶
type HostOption func(ctx context.Context, id peer.ID, ps pstore.Peerstore, bwr metrics.Reporter, fs []*net.IPNet, tpt smux.Transport) (p2phost.Host, error)
var DefaultHostOption HostOption = constructPeerHost
type IpfsNode ¶
type IpfsNode struct {
// Self
Identity peer.ID // the local node's identity
Repo repo.Repo
// Local node
Pinning pin.Pinner // the pinning manager
Mounts Mounts // current mount state, if any.
PrivateKey ic.PrivKey // the local node's private Key
// Services
Peerstore pstore.Peerstore // storage for other Peer instances
Blockstore bstore.GCBlockstore // the block store (lower level)
Blocks bserv.BlockService // the block service, get/add blocks.
DAG merkledag.DAGService // the merkle dag service, get/add objects.
Resolver *path.Resolver // the path resolution system
Reporter metrics.Reporter
Discovery discovery.Service
FilesRoot *mfs.Root
// Online
PeerHost p2phost.Host // the network host (server+client)
Bootstrapper io.Closer // the periodic bootstrapper
Routing routing.IpfsRouting // the routing system. recommend ipfs-dht
Exchange exchange.Interface // the block exchange + strategy (bitswap)
Namesys namesys.NameSystem // the name system, resolves paths to hashes
Diagnostics *diag.Diagnostics // the diagnostics service
Ping *ping.PingService
Reprovider *rp.Reprovider // the value reprovider system
IpnsRepub *ipnsrp.Republisher
Floodsub *floodsub.PubSub
// contains filtered or unexported fields
}
IpfsNode is IPFS Core module. It represents an IPFS instance.
func (*IpfsNode) Close ¶ added in v0.3.6
func (n *IpfsNode) Close() error
Close calls Close() on the Process object
func (*IpfsNode) Context ¶ added in v0.3.6
func (n *IpfsNode) Context() context.Context
Context returns the IpfsNode context
func (*IpfsNode) GetKey ¶ added in v0.4.5
func (n *IpfsNode) GetKey(name string) (ic.PrivKey, error)
func (*IpfsNode) HandlePeerFound ¶ added in v0.3.2
func (n *IpfsNode) HandlePeerFound(p pstore.PeerInfo)
func (*IpfsNode) LoadPrivateKey ¶
func (n *IpfsNode) LoadPrivateKey() error
func (*IpfsNode) OnlineMode ¶
func (n *IpfsNode) OnlineMode() bool
func (*IpfsNode) Process ¶ added in v0.3.6
func (n *IpfsNode) Process() goprocess.Process
Process returns the Process object
func (*IpfsNode) SetupOfflineRouting ¶
func (n *IpfsNode) SetupOfflineRouting() error
SetupOfflineRouting loads the local nodes private key and uses it to instantiate a routing system in offline mode. This is primarily used for offline ipns modifications.
type Mounts ¶
type Mounts struct {
Ipfs mount.Mount
Ipns mount.Mount
}
Mounts defines what the node's mount state is. This should perhaps be moved to the daemon or mount. It's here because it needs to be accessible across daemon requests.
type RoutingOption ¶
type RoutingOption func(context.Context, p2phost.Host, repo.Datastore) (routing.IpfsRouting, error)
var DHTClientOption RoutingOption = constructClientDHTRouting
var DHTOption RoutingOption = constructDHTRouting
var NilRouterOption RoutingOption = nilrouting.ConstructNilRouting
