Functions

func ChangeSourceString added in v0.106.0 

func ChangeSourceString(changeSource ChangeSource) string

func ChangeTypeString added in v0.106.0 

func ChangeTypeString(changeType ChangeType) string

func FindIndices 

func FindIndices(root string) ([]string, error)

FindIndices searches the specified root directory for index files, returning their relative directory paths while skipping hidden folders.

func IndexExists 

func IndexExists(baseAbs string) (bool, error)

func ListRemote added in v0.106.0 

func ListRemote(ctx context.Context, client apigen.ClientWithResponsesInterface, loc *uri.URI, objects chan<- apigen.ObjectStats, includeDirs bool) error

ListRemote - Lists objects from a remote uri and inserts them into the objects channel

func WalkS3 added in v1.26.0 

func WalkS3(root string, callbackFunc func(p string, info fs.FileInfo, err error) error) error

WalkS3 - walk like an Egyptian... ¯\_(ツ)¯\_ This walker function simulates the way object listing is performed by S3. Contrary to how a standard FS walk function behaves, S3 does not take into consideration the directory hierarchy. Instead, object paths include the entire path relative to the root and as a result the directory or "path separator" is also taken into account when providing the listing in a lexicographical order.

	Source ChangeSource
	Path   string
	Type   ChangeType
}

func DiffLocalWithHead added in v0.106.0 

func DiffLocalWithHead(left <-chan apigen.ObjectStats, rightPath string, includeDirs, includePOSIXPermissions bool) (Changes, error)

DiffLocalWithHead Checks changes between a local directory and the head it is pointing to. The diff check assumes the remote is an immutable set so any changes found resulted from changes in the local directory left is an object channel which contains results from a remote source. rightPath is the local directory to diff with
