Constants

const (
    DefaultNodeAddr           = "/ip4/127.0.0.1/tcp/5001"
    DefaultConnectSwarmsDelay = 30 * time.Second
    DefaultPinMethod          = "refs"
    DefaultIPFSRequestTimeout = 5 * time.Minute
    DefaultPinTimeout         = 24 * time.Hour
    DefaultUnpinTimeout       = 3 * time.Hour
)

Default values for Config.

Variables

var DNSTimeout = 5 * time.Second

DNSTimeout is used when resolving DNS multiaddresses in this module

type Config Uses

type Config struct {
    config.Saver

    // Host/Port for the IPFS daemon.
    NodeAddr ma.Multiaddr

    // ConnectSwarmsDelay specifies how long to wait after startup before
    // attempting to open connections from this peer's IPFS daemon to the
    // IPFS daemons of other peers.
    ConnectSwarmsDelay time.Duration

    // "pin" or "refs". "pin" uses a "pin/add" call. "refs" uses a
    // "refs -r" call followed by "pin/add". "refs" allows fetching in
    // parallel but should be used with GC disabled.
    PinMethod string

    // IPFS Daemon HTTP Client POST timeout
    IPFSRequestTimeout time.Duration

    // Pin Operation timeout
    PinTimeout time.Duration

    // Unpin Operation timeout
    UnpinTimeout time.Duration
}

Config is used to initialize a Connector and allows to customize its behaviour. It implements the config.ComponentConfig interface.

func (*Config) ConfigKey Uses

func (cfg *Config) ConfigKey() string

ConfigKey provides a human-friendly identifier for this type of Config.

func (*Config) Default Uses

func (cfg *Config) Default() error

Default sets the fields of this Config to sensible default values.

func (*Config) LoadJSON Uses

func (cfg *Config) LoadJSON(raw []byte) error

LoadJSON parses a JSON representation of this Config as generated by ToJSON.

func (*Config) ToJSON Uses

func (cfg *Config) ToJSON() (raw []byte, err error)

ToJSON generates a human-friendly JSON representation of this Config.

func (*Config) Validate Uses

func (cfg *Config) Validate() error

Validate checks that the fields of this Config have sensible values, at least in appearance.

type Connector Uses

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

Connector implements the IPFSConnector interface and provides a component which is used to perform on-demand requests against the configured IPFS daemom (such as a pin request).

func NewConnector Uses

func NewConnector(cfg *Config) (*Connector, error)

NewConnector creates the component and leaves it ready to be started

func (*Connector) BlockGet Uses

func (ipfs *Connector) BlockGet(c cid.Cid) ([]byte, error)

BlockGet retrieves an ipfs block with the given cid

func (*Connector) BlockPut Uses

func (ipfs *Connector) BlockPut(b api.NodeWithMeta) error

BlockPut triggers an ipfs block put on the given data, inserting the block into the ipfs daemon's repo.

func (*Connector) ConfigKey Uses

func (ipfs *Connector) ConfigKey(keypath string) (interface{}, error)

ConfigKey fetches the IPFS daemon configuration and retrieves the value for a given configuration key. For example, "Datastore/StorageMax" will return the value for StorageMax in the Datastore configuration object.

func (*Connector) ConnectSwarms Uses

func (ipfs *Connector) ConnectSwarms() error

ConnectSwarms requests the ipfs addresses of other peers and triggers ipfs swarm connect requests

func (*Connector) ID Uses

func (ipfs *Connector) ID() (api.IPFSID, error)

ID performs an ID request against the configured IPFS daemon. It returns the fetched information. If the request fails, or the parsing fails, it returns an error and an empty IPFSID which also contains the error message.

func (*Connector) Pin Uses

func (ipfs *Connector) Pin(ctx context.Context, hash cid.Cid, maxDepth int) error

Pin performs a pin request against the configured IPFS daemon.

func (*Connector) PinLs Uses

func (ipfs *Connector) PinLs(ctx context.Context, typeFilter string) (map[string]api.IPFSPinStatus, error)

PinLs performs a "pin ls --type typeFilter" request against the configured IPFS daemon and returns a map of cid strings and their status.

func (*Connector) PinLsCid Uses

func (ipfs *Connector) PinLsCid(ctx context.Context, hash cid.Cid) (api.IPFSPinStatus, error)

PinLsCid performs a "pin ls <hash>" request. It first tries with "type=recursive" and then, if not found, with "type=direct". It returns an api.IPFSPinStatus for that hash.

func (*Connector) RepoStat Uses

func (ipfs *Connector) RepoStat() (api.IPFSRepoStat, error)

RepoStat returns the DiskUsage and StorageMax repo/stat values from the ipfs daemon, in bytes, wrapped as an IPFSRepoStat object.

func (*Connector) SetClient Uses

func (ipfs *Connector) SetClient(c *rpc.Client)

SetClient makes the component ready to perform RPC requests.

func (*Connector) Shutdown Uses

func (ipfs *Connector) Shutdown() error

Shutdown stops any listeners and stops the component from taking any requests.

func (*Connector) SwarmPeers Uses

func (ipfs *Connector) SwarmPeers() (api.SwarmPeers, error)

SwarmPeers returns the peers currently connected to this ipfs daemon.

func (*Connector) Unpin Uses

func (ipfs *Connector) Unpin(ctx context.Context, hash cid.Cid) error

Unpin performs an unpin request against the configured IPFS daemon.
