Types

type Config added in v0.2.0

type Config struct {
	config.Saver

	// Listen parameters for the IPFS Proxy. Used by the IPFS
	// connector component.
	ProxyAddr ma.Multiaddr

	// 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

	// Maximum duration before timing out reading a full request
	ProxyReadTimeout time.Duration
	// Maximum duration before timing out reading the headers of a request
	ProxyReadHeaderTimeout time.Duration

	// Maximum duration before timing out write of the response
	ProxyWriteTimeout time.Duration

	// Server-side amount of time a Keep-Alive connection will be
	// kept idle before being reused
	ProxyIdleTimeout 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 added in v0.2.0

func (cfg *Config) ConfigKey() string

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

func (*Config) Default added in v0.2.0

func (cfg *Config) Default() error

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

func (*Config) LoadJSON added in v0.2.0

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

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

func (*Config) ToJSON added in v0.2.0

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

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

func (*Config) Validate added in v0.2.0

func (cfg *Config) Validate() error

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

type Connector

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

Connector implements the IPFSConnector interface and provides a component which does two tasks:

On one side, it proxies HTTP requests to the configured IPFS daemon. It is able to intercept these requests though, and perform extra operations on them.

On the other side, it is used to perform on-demand requests against the configured IPFS daemom (such as a pin request).

func NewConnector

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

NewConnector creates the component and leaves it ready to be started

func (*Connector) BlockGet added in v0.5.0

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

BlockGet retrieves an ipfs block with the given cid

func (*Connector) BlockPut added in v0.5.0

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

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

func (ipfs *Connector) ConnectSwarms() error

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

func (*Connector) ID

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

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

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

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 added in v0.5.0

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

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

SetClient makes the component ready to perform RPC requests.

func (*Connector) Shutdown

func (ipfs *Connector) Shutdown() error

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

func (*Connector) SwarmPeers added in v0.3.3

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

SwarmPeers returns the peers currently connected to this ipfs daemon.

func (*Connector) Unpin

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

Unpin performs an unpin request against the configured IPFS daemon.
