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

    // Tracing flag used to skip tracing specific paths when not enabled.
    Tracing bool
}

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

func (*Config) ApplyEnvVars Uses

func (cfg *Config) ApplyEnvVars() error

ApplyEnvVars fills in any Config fields found as environment variables.

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(ctx context.Context, c cid.Cid) ([]byte, error)

BlockGet retrieves an ipfs block with the given cid

func (*Connector) BlockPut Uses

func (ipfs *Connector) BlockPut(ctx context.Context, 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(ctx context.Context) error

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

func (*Connector) ID Uses

func (ipfs *Connector) ID(ctx context.Context) (*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.

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(ctx context.Context) (*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) Resolve Uses

func (ipfs *Connector) Resolve(ctx context.Context, path string) (cid.Cid, error)

Resolve accepts ipfs or ipns path and resolves it into a cid

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(ctx context.Context) error

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

func (*Connector) SwarmPeers Uses

func (ipfs *Connector) SwarmPeers(ctx context.Context) ([]peer.ID, 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.
