Functions ¶
func ServeStaticFile ¶
ServeStaticFile serves file from the root virtual filesystem.
Types ¶
type DownloadHandler ¶
type DownloadHandler struct { Fetcher blob.Fetcher // Search is optional. If present, it's used to map a fileref // to a wholeref, if the Fetcher is of a type that knows how // to get at a wholeref more efficiently. (e.g. blobpacked) Search *search.Handler ForceMIME string // optional // contains filtered or unexported fields }
func (*DownloadHandler) ServeFile ¶
func (dh *DownloadHandler) ServeFile(w http.ResponseWriter, r *http.Request, file blob.Ref)
func (*DownloadHandler) ServeHTTP ¶
func (dh *DownloadHandler) ServeHTTP(w http.ResponseWriter, r *http.Request)
ServeHTTP answers the following queries:
POST:
?files=sha1-foo,sha1-bar,sha1-baz
Creates a zip archive of the provided files and serves it in the response.
GET:
/<file-schema-blobref>[?inline=1]
Serves the file described by the requested file schema blobref. if inline=1 the Content-Disposition of the response is set to inline, and otherwise it set to attachment.
type FileTreeHandler ¶
func (*FileTreeHandler) ServeHTTP ¶
func (fth *FileTreeHandler) ServeHTTP(rw http.ResponseWriter, req *http.Request)
type FileTreeNode ¶
type FileTreeNode struct { // Name is the basename of the node. Name string `json:"name"` // Type is the camliType of the node. This may be "file", "directory", "symlink" // or other in the future. Type schema.CamliType `json:"type"` // BlobRef is the blob.Ref of the node. BlobRef blob.Ref `json:"blobRef"` }
FileTreeNode represents a file in a file tree. It is part of the FileTreeResponse.
type FileTreeResponse ¶
type FileTreeResponse struct { // Children is the list of children files of a directory. Children []FileTreeNode `json:"children"` }
FileTreeResponse is the JSON response for the FileTreeHandler.
type HelpHandler ¶
type HelpHandler struct {
// contains filtered or unexported fields
}
HelpHandler publishes information related to accessing the server
func (*HelpHandler) InitHandler ¶
func (hh *HelpHandler) InitHandler(hl blobserver.FindHandlerByTyper) error
func (*HelpHandler) ServeHTTP ¶
func (hh *HelpHandler) ServeHTTP(rw http.ResponseWriter, req *http.Request)
func (*HelpHandler) SetServerConfig ¶
func (hh *HelpHandler) SetServerConfig(config jsonconfig.Obj)
SetServerConfig enables the handler to receive the server config before InitHandler, which generates a client config from the server config, is called.
type ImageHandler ¶
type ImageHandler struct { Fetcher blob.Fetcher Search *search.Handler // optional Cache blobserver.Storage // optional MaxWidth, MaxHeight int Square bool ThumbMeta *ThumbMeta // optional cache index for scaled images ResizeSem *syncutil.Sem // Limit peak RAM used by concurrent image thumbnail calls. }
func (*ImageHandler) ServeHTTP ¶
func (ih *ImageHandler) ServeHTTP(rw http.ResponseWriter, req *http.Request, file blob.Ref)
type RootHandler ¶
type RootHandler struct { // Stealth determines whether we hide from non-authenticated // clients. Stealth bool OwnerName string // for display purposes only. Username string // default user for mobile setup. // URL prefixes (path or full URL) to the primary blob and // search root. BlobRoot string SearchRoot string Prefix string // root handler's prefix // JSONSignRoot is the optional path or full URL to the JSON // Signing helper. JSONSignRoot string Storage blobserver.Storage // of BlobRoot, or nil // contains filtered or unexported fields }
RootHandler handles serving the about/splash page.
func (*RootHandler) SearchHandler ¶
func (rh *RootHandler) SearchHandler() (h *search.Handler, ok bool)
func (*RootHandler) ServeHTTP ¶
func (rh *RootHandler) ServeHTTP(w http.ResponseWriter, r *http.Request)
type StatusHandler ¶
type StatusHandler struct {
// contains filtered or unexported fields
}
StatusHandler publishes server status information.
func (*StatusHandler) InitHandler ¶
func (sh *StatusHandler) InitHandler(hl blobserver.FindHandlerByTyper) error
func (*StatusHandler) ServeHTTP ¶
func (sh *StatusHandler) ServeHTTP(rw http.ResponseWriter, req *http.Request)
type SyncHandler ¶
type SyncHandler struct {
// contains filtered or unexported fields
}
The SyncHandler handles async replication in one direction between a pair storage targets, a source and target.
SyncHandler is a BlobReceiver but doesn't actually store incoming blobs; instead, it records blobs it has received and queues them for async replication soon, or whenever it can.
func NewSyncHandler ¶
func NewSyncHandler(srcName, destName string, src blobserver.Storage, dest blobReceiverEnumerator, pendingQueue sorted.KeyValue) *SyncHandler
NewSyncHandler returns a handler that will asynchronously and continuously copy blobs from src to dest, if missing on dest. Blobs waiting to be copied are stored on pendingQueue. srcName and destName are only used for status and debugging messages. N.B: blobs should be added to src with a method that notifies the blob hub, such as blobserver.Receive.
func (*SyncHandler) EnumerateBlobs ¶
func (*SyncHandler) Fetch ¶
func (sh *SyncHandler) Fetch(context.Context, blob.Ref) (file io.ReadCloser, size uint32, err error)
func (*SyncHandler) IdleWait ¶
func (sh *SyncHandler) IdleWait()
IdleWait waits until the sync handler has finished processing the currently queued blobs.
func (*SyncHandler) InitHandler ¶
func (sh *SyncHandler) InitHandler(hl blobserver.FindHandlerByTyper) error
func (*SyncHandler) ReceiveBlob ¶
func (*SyncHandler) RemoveBlobs ¶
func (*SyncHandler) ServeHTTP ¶
func (sh *SyncHandler) ServeHTTP(rw http.ResponseWriter, req *http.Request)
func (*SyncHandler) String ¶
func (sh *SyncHandler) String() string
type ThumbMeta ¶
type ThumbMeta struct {
// contains filtered or unexported fields
}
ThumbMeta is a mapping from an image's scaling parameters (encoding as an opaque "key" string) and the blobref of the thumbnail (currently its file schema blob). ThumbMeta is safe for concurrent use by multiple goroutines.
The key will be some string containing the original full-sized image's blobref, its target dimensions, and any possible transformations on it (e.g. cropping it to square).
func NewThumbMeta ¶
NewThumbMeta returns a new in-memory ThumbMeta, backed with the optional kv. If kv is nil, key/value pairs are stored in memory only.
type UIHandler ¶
type UIHandler struct { // Cache optionally specifies a cache blob server, used for // caching image thumbnails and other emphemeral data. Cache blobserver.Storage // or nil // contains filtered or unexported fields }
UIHandler handles serving the UI and discovery JSON.
func (*UIHandler) InitHandler ¶
func (ui *UIHandler) InitHandler(hl blobserver.FindHandlerByTyper) error
InitHandler goes through all the other configured handlers to discover the publisher ones, and uses them to populate ui.publishRoots.
