Functions ¶

func TarFromWriterTo ¶

func TarFromWriterTo(wt WriterToTar) io.ReadCloser

TarFromWriterTo is used to create a tar stream from a tar record creator. This can be used to manufacture more specific tar records which allow testing specific tar cases which may be encountered by the untar process.

Types ¶

type TarContext ¶

type TarContext struct {
	UID int
	GID int

	// ModTime sets the modtimes for all files, if nil the current time
	// is used for each file when it was written
	ModTime *time.Time

	Xattrs map[string]string
}

TarContext is used to create tar records

func (TarContext) Dir ¶

func (tc TarContext) Dir(name string, perm os.FileMode) WriterToTar

Dir returns a directory tar entry

func (TarContext) File ¶

func (tc TarContext) File(name string, content []byte, perm os.FileMode) WriterToTar

File returns a regular file tar entry using the provided bytes

func (TarContext) Link ¶

func (tc TarContext) Link(oldname, newname string) WriterToTar

WithUIDGID sets the UID and GID for tar entries

func (TarContext) WithXattrs ¶

func (tc TarContext) WithXattrs(xattrs map[string]string) TarContext

WithXattrs adds these xattrs to all files, merges with any previously added xattrs

type WriterToTar ¶

type WriterToTar interface {
	WriteTo(*tar.Writer) error
}
