Types

type ChecksumStorage added in v1.1.0

type ChecksumStorage interface {
	// Get finds checksums in DB by path
	Get(path string) (*utils.ChecksumInfo, error)
	// Update adds or updates information about checksum in DB
	Update(path string, c *utils.ChecksumInfo) error
}

ChecksumStorage is stores checksums in some (persistent) storage

type ConsoleResultReporter added in v0.9.1

type ConsoleResultReporter struct {
	Progress Progress
}

ConsoleResultReporter is implementation of ResultReporter that prints in colors to console

func (*ConsoleResultReporter) Added added in v0.9.1

func (c *ConsoleResultReporter) Added(msg string, a ...interface{})

Added is signal that something has been added (green)

func (*ConsoleResultReporter) Removed added in v0.9.1

func (c *ConsoleResultReporter) Removed(msg string, a ...interface{})

Removed is signal that something has been removed (red)

func (*ConsoleResultReporter) Warning added in v0.9.1

func (c *ConsoleResultReporter) Warning(msg string, a ...interface{})

Warning is non-fatal error message (yellow)

type Downloader

type Downloader interface {
	// Download starts new download task
	Download(url string, destination string) error
	// DownloadWithChecksum starts new download task with checksum verification
	DownloadWithChecksum(url string, destination string, expected *utils.ChecksumInfo, ignoreMismatch bool, maxTries int) error
	// GetProgress returns Progress object
	GetProgress() Progress
}

Downloader is parallel HTTP fetcher

type FileSystemPublishedStorage added in v1.1.0

type FileSystemPublishedStorage interface {
	// PublicPath returns root of public part
	PublicPath() string
}

FileSystemPublishedStorage is published storage on filesystem

type LocalPackagePool added in v1.1.0

type LocalPackagePool interface {
	// GenerateTempPath generates temporary path for download (which is fast to import into package pool later on)
	GenerateTempPath(filename string) (string, error)
	// Link generates hardlink to destination path
	Link(path, dstPath string) error
	// Symlink generates symlink to destination path
	Symlink(path, dstPath string) error
	// FullPath generates full path to the file in pool
	//
	// Please use with care: it's not supposed to be used to access files
	FullPath(path string) string
}

LocalPackagePool is implemented by PackagePools residing on the same filesystem

type PackagePool

type PackagePool interface {
	// Verify checks whether file exists in the pool and fills back checksum info
	//
	// if poolPath is empty, poolPath is generated automatically based on checksum info (if available)
	// in any case, if function returns true, it also fills back checksums with complete information about the file in the pool
	Verify(poolPath, basename string, checksums *utils.ChecksumInfo, checksumStorage ChecksumStorage) (string, bool, error)
	// Import copies file into package pool
	//
	// - srcPath is full path to source file as it is now
	// - basename is desired human-readable name (canonical filename)
	// - checksums are used to calculate file placement
	// - move indicates whether srcPath can be removed
	Import(srcPath, basename string, checksums *utils.ChecksumInfo, move bool, storage ChecksumStorage) (path string, err error)
	// LegacyPath returns legacy (pre 1.1) path to package file (relative to root)
	LegacyPath(filename string, checksums *utils.ChecksumInfo) (string, error)
	// Stat returns Unix stat(2) info
	Stat(path string) (os.FileInfo, error)
	// Open returns ReadSeekerCloser to access the file
	Open(path string) (ReadSeekerCloser, error)
	// FilepathList returns file paths of all the files in the pool
	FilepathList(progress Progress) ([]string, error)
	// Remove deletes file in package pool returns its size
	Remove(path string) (size int64, err error)
}

PackagePool is asbtraction of package pool storage.

PackagePool stores all the package files, deduplicating them.

type Progress

type Progress interface {
	// Writer interface to support progress bar ticking
	io.Writer
	// Start makes progress start its work
	Start()
	// Shutdown shuts down progress display
	Shutdown()
	// Flush returns when all queued messages are sent
	Flush()
	// InitBar starts progressbar for count bytes or count items
	InitBar(count int64, isBytes bool)
	// ShutdownBar stops progress bar and hides it
	ShutdownBar()
	// AddBar increments progress for progress bar
	AddBar(count int)
	// SetBar sets current position for progress bar
	SetBar(count int)
	// Printf does printf but in safe manner: not overwriting progress bar
	Printf(msg string, a ...interface{})
	// ColoredPrintf does printf in colored way + newline
	ColoredPrintf(msg string, a ...interface{})
	// PrintfStdErr does printf but in safe manner to stderr
	PrintfStdErr(msg string, a ...interface{})
}

Progress is a progress displaying entity, it allows progress bars & simple prints

type PublishedStorage

type PublishedStorage interface {
	// MkDir creates directory recursively under public path
	MkDir(path string) error
	// PutFile puts file into published storage at specified path
	PutFile(path string, sourceFilename string) error
	// RemoveDirs removes directory structure under public path
	RemoveDirs(path string, progress Progress) error
	// Remove removes single file under public path
	Remove(path string) error
	// LinkFromPool links package file from pool to dist's pool location
	LinkFromPool(publishedDirectory, baseName string, sourcePool PackagePool, sourcePath string, sourceChecksums utils.ChecksumInfo, force bool) error
	// Filelist returns list of files under prefix
	Filelist(prefix string) ([]string, error)
	// RenameFile renames (moves) file
	RenameFile(oldName, newName string) error
}

PublishedStorage is abstraction of filesystem storing all published repositories

type PublishedStorageProvider added in v0.7.1

type PublishedStorageProvider interface {
	// GetPublishedStorage returns PublishedStorage by name
	GetPublishedStorage(name string) PublishedStorage
}

PublishedStorageProvider is a thing that returns PublishedStorage by name

type ReadSeekerCloser added in v1.1.0

type ReadSeekerCloser interface {
	io.ReadSeeker
	io.Closer
}

ReadSeekerCloser = ReadSeeker + Closer

type RecordingResultReporter added in v0.9.1

type RecordingResultReporter struct {
	Warnings     []string
	AddedLines   []string `json:"Added"`
	RemovedLines []string `json:"Removed"`
}

RecordingResultReporter is implementation of ResultReporter that collects all messages

func (*RecordingResultReporter) Added added in v0.9.1

func (r *RecordingResultReporter) Added(msg string, a ...interface{})

Added is signal that something has been added

func (*RecordingResultReporter) Removed added in v0.9.1

func (r *RecordingResultReporter) Removed(msg string, a ...interface{})

Removed is signal that something has been removed

func (*RecordingResultReporter) Warning added in v0.9.1

func (r *RecordingResultReporter) Warning(msg string, a ...interface{})

Warning is non-fatal error message

type ResultReporter added in v0.9.1

type ResultReporter interface {
	// Warning is non-fatal error message
	Warning(msg string, a ...interface{})
	// Removed is signal that something has been removed
	Removed(msg string, a ...interface{})
	// Added is signal that something has been added
	Added(msg string, a ...interface{})
}

ResultReporter is abstraction for result reporting from complex processing functions
