Types

type ActiveRemoteRequests

type ActiveRemoteRequests struct {
	sync.Mutex
	// The string key is an mxc:// URL
	MXCToResult map[string]*RemoteRequestResult
}

ActiveRemoteRequests is a lockable map of media URIs requested from remote homeservers It is used for ensuring multiple requests for the same file do not clobber each other.

type ActiveThumbnailGeneration

type ActiveThumbnailGeneration struct {
	sync.Mutex
	// The string key is a thumbnail file path
	PathToResult map[string]*ThumbnailGenerationResult
}

ActiveThumbnailGeneration is a lockable map of file paths being thumbnailed It is used to ensure thumbnails are only generated once.

type Base64Hash string

Base64Hash is a base64 URLEncoding string representation of a SHA-256 hash sum

}

MediaMetadata is metadata associated with a media file

type Path

type Path string

Path is an absolute or relative UNIX filesystem path

type RemoteRequestResult

type RemoteRequestResult struct {
	// Condition used for the requester to signal the result to all other routines waiting on this condition
	Cond *sync.Cond
	// MediaMetadata of the requested file to avoid querying the database for every waiting routine
	MediaMetadata *MediaMetadata
	// An error, nil in case of no error.
	Error error
}

RemoteRequestResult is used for broadcasting the result of a request for a remote file to routines waiting on the condition

type RequestMethod

type RequestMethod string

RequestMethod is an HTTP request method i.e. GET, POST, etc

type ThumbnailGenerationResult

type ThumbnailGenerationResult struct {
	// Condition used for the generator to signal the result to all other routines waiting on this condition
	Cond *sync.Cond
	// Resulting error from the generation attempt
	Err error
}

ThumbnailGenerationResult is used for broadcasting the result of thumbnail generation to routines waiting on the condition

type ThumbnailMetadata

type ThumbnailMetadata struct {
	MediaMetadata *MediaMetadata
	ThumbnailSize ThumbnailSize
}

ThumbnailMetadata contains the metadata about an individual thumbnail
