type Client struct {

    // Verbose controls how much logging from the client is printed. The caller
    // should set it only before using the client, and treat it as read-only after
    // that.
    Verbose bool
    // Logger is the logger used by the client. It defaults to a standard
    // logger to os.Stderr if the client is initialized by one of the package's
    // functions. Like Verbose, it should be set only before using the client, and
    // not be modified afterwards.
    Logger *log.Logger
    // contains filtered or unexported fields
}

A Client provides access to a Perkeep server.

After use, a Client should be closed via its Close method to release idle HTTP connections or other resourcedds.

func New

func New(opts ...ClientOption) (*Client, error)

New returns a new Perkeep Client.

By default, with no options, it uses the client as configured in the environment or default configuration files.

If the client's config has some trusted certs, the server's certificate will be checked against those in the config after the TLS handshake.

func (*Client) DiscoveryDoc

func (c *Client) DiscoveryDoc(ctx context.Context) (io.Reader, error)

DiscoveryDoc returns the server's JSON discovery document. This method exists purely for the "camtool discovery" command. Clients shouldn't have to parse this themselves.

func (*Client) IsIgnoredFile

func (c *Client) IsIgnoredFile(fullpath string) bool

IsIgnoredFile returns whether the file at fullpath should be ignored by pk-put. The fullpath is checked against the ignoredFiles list, trying the following rules in this order: 1) star-suffix style matching (.e.g *.jpg). 2) Shell pattern match as done by http://golang.org/pkg/path/filepath/#Match 3) If the pattern is an absolute path to a directory, fullpath matches if it is that directory or a child of it. 4) If the pattern is a relative path, fullpath matches if it has pattern as a path component (i.e the pattern is a part of fullpath that fits exactly between two path separators).

func (c *Client) RemoveBlobs(ctx context.Context, blobs []blob.Ref) error

RemoveBlobs removes the list of blobs. An error is returned if the server failed to remove a blob. Removing a non-existent blob isn't an error.

func (*Client) SearchExistingFileSchema

func (c *Client) SearchExistingFileSchema(ctx context.Context, wholeRef ...blob.Ref) (blob.Ref, error)

SearchExistingFileSchema does a search query looking for an existing file with entire contents of wholeRef, then does a HEAD request to verify the file still exists on the server. If so, it returns that file schema's blobref.

If multiple wholeRef values are provided, any may match. This is used for searching for the file by multiple wholeRef hashes (e.g. SHA-224 and SHA-1).

It returns (zero, nil) if not found. A non-nil error is only returned if there were problems searching.

func (*Client) SearchRoot

func (c *Client) SearchRoot() (string, error)

func (*Client) Stats

func (c *Client) Stats() Stats

func (*Client) StorageGeneration

func (c *Client) StorageGeneration() (string, error)

StorageGeneration returns the server's unique ID for its storage generation, reset whenever storage is reset, moved, or partially lost.

This is a value that can be used in client cache keys to add certainty that they're talking to the same instance as previously.

If the server doesn't return such a value, the error will be ErrNoStorageGeneration.

func (*Client) SyncHandlers

func (c *Client) SyncHandlers() ([]*SyncInfo, error)

SyncHandlers returns the server's sync handlers "from" and "to" prefix URLs. If the server isn't running any sync handler, the error will be ErrNoSync.

func (*Client) UpdateShareChain

func (c *Client) UpdateShareChain(b blob.Ref, r io.Reader) error

UpdateShareChain reads the schema of b from r, and instructs the client that all blob refs found in this schema should use b as a preceding chain link, in all subsequent shared blobs fetches. If the client was not created with NewFromShareRoot, ErrNotSharing is returned.

func (*Client) UploadFile

func (c *Client) UploadFile(ctx context.Context, filename string, contents io.Reader, opts *FileUploadOptions) (blob.Ref, error)

UploadFile uploads the contents of the file, as well as a file blob with filename for these contents. If the contents or the file blob are found on the server, they're not uploaded.

Note: this method is still a work in progress, and might change to accommodate the needs of pk-put file.

func (*Client) UploadNewPermanode

func (c *Client) UploadNewPermanode(ctx context.Context) (*PutResult, error)

func (*Client) UploadPlannedPermanode

func (c *Client) UploadPlannedPermanode(ctx context.Context, key string, sigTime time.Time) (*PutResult, error)

func (*Client) UploadPublicKey

func (c *Client) UploadPublicKey(ctx context.Context) error

UploadPublicKey uploads the public key (if one is defined), so subsequent (likely synchronous) indexing of uploaded signed blobs will have access to the public key to verify it. In the normal case, the stat cache prevents this from doing anything anyway.

type ClientOption

func OptionNoExternalConfig

func OptionNoExternalConfig() ClientOption

OptionNoExternalConfig returns a Client constructor option that prevents any on-disk config files or environment variables from influencing the client. It may still use the disk for caches.

func OptionServer

func OptionServer(server string) ClientOption

OptionServer returns a Client constructor option that forces use of the provided server.

The provided server is either "host:port" (assumed http, not https) or a URL prefix, with or without a path, or a server alias from the client configuration file. A server alias should not be confused with a hostname, therefore it cannot contain any colon or period.

func OptionTransportConfig

func OptionTransportConfig(tc *TransportConfig) ClientOption

OptionTransportConfig returns a ClientOption that makes the client use the provided transport configuration options.

func OptionTrustedCert

func OptionTrustedCert(cert string) ClientOption

OptionTrustedCert returns a ClientOption that makes the client trust the provide self-signed cert signature. The value should be the 20 byte hex prefix of the SHA-256 of the cert, as printed by the perkeepd server on start-up.

If cert is empty, the option has no effect.

func OptionUseStorageClient

func OptionUseStorageClient(s blobserver.Storage) ClientOption

OptionUseStorageClient returns a Client constructor option that forces use of the provided blob storage target.

This exists mainly so all the convenience methods on Client (e.g. the Upload variants) are available against storage directly.

Use of OptionUseStorageClient is mutually exclusively with all other options, although it does imply OptionNoExternalConfig(true).

type EnumerateOpts

type EnumerateOpts struct {
    After   string        // last blobref seen; start with ones greater than this
    MaxWait time.Duration // how long to poll for (second granularity), waiting for any blob, or 0 for no limit

type FileUploadOptions

type FileUploadOptions struct {
    // FileInfo optionally specifies the FileInfo to populate the schema of the file blob.
    FileInfo os.FileInfo
    // WholeRef optionally specifies the digest of the uploaded file contents, which
    // allows UploadFile to skip computing the digest (needed to check if the contents
    // are already on the server).
    WholeRef blob.Ref
}

FileUploadOptions is optionally provided to UploadFile.

type HaveCache

type HaveCache interface {

    // The number of uploads that were requested, but perhaps
    // not actually performed if the server already had the items.
    UploadRequests ByCountAndBytes

    // The uploads which were actually sent to the blobserver
    // due to the server not having the blobs
    Uploads ByCountAndBytes
}

func (*Stats) String

func (s *Stats) String() string

type SyncInfo

type SyncInfo struct {
    From    string
    To      string
    ToIndex bool // whether this sync is from a blob storage to an index
}

type TransportConfig

type TransportConfig struct {
    // Proxy optionally specifies the Proxy for the transport. Useful with
    // pk-put for debugging even localhost requests.
    Proxy   func(*http.Request) (*url.URL, error)
    Verbose bool // Verbose enables verbose logging of HTTP requests.
}

TransportConfig contains options for how HTTP requests are made.

type UploadHandle

type UploadHandle struct {
    // BlobRef is the required blobref of the blob to upload.
    BlobRef blob.Ref

    // Contents is the blob data.
    Contents io.Reader

    // Size optionally specifies the size of Contents.
    // If <= 0, the Contents are slurped into memory to count the size.
    Size uint32

    // Vivify optionally instructs the server to create a
    // permanode for this blob. If used, the blob should be a
    // "file" schema blob. This is typically used by
    // lesser-trusted clients (such a mobile phones) which don't
    // have rights to do signing directly.
    Vivify bool

    // SkipStat indicates whether the stat check (checking whether
    // the server already has the blob) will be skipped and the
    // blob should be uploaded immediately. This is useful for
    // small blobs that the server is unlikely to already have
    // (e.g. new claims).
    SkipStat bool
}

UploadHandle contains the parameters is a request to upload a blob.

func NewUploadHandleFromString
