Functions

func CopyToTempDir 

func CopyToTempDir(localPath string, includePath string) (tempDir string, err error)

func Sync 

func Sync(sourceRepository Repository, sourcePath string, destRepository Repository, destPath string) error

Sync destRepository/destPath to match sourceRepository/sourcePath

- If file exists in source, but not in dest, it will copy from source to dest - If file exists in both but different content, it will copy from source to dest - If file exists in dest but not in source, it will delete in dest

Types

type CachedRepository 

type CachedRepository struct {
	// contains filtered or unexported fields
}

CachedRepository wraps another repository, caching a prefix in a local directory.

SyncCache() syncs cachePrefix locally, which you must call before doing any reads. It is not done automatically so you can control output to the user about syncing.

If a read hits a path starting with cachePrefix, it will use the local cached version.

Repository represents a blob store

TODO: this interface needs trimming. A lot of things exist on this interface for the shared library with Python, but perhaps we could detatch that API from this. For example, this API could provide a GetPath with reader, then the shared API could add extracting from tarball on top of that.
