Functions

func AreEtagsSame added in v1.0.14 

func AreEtagsSame(e1, e2 string) bool

AreEtagsSame compares 2 etags by ignoring quotes

func EvaluateMatchPreconditions added in v1.0.18 

func EvaluateMatchPreconditions(etag string, ifMatch, ifNoneMatch *string) error

EvaluateObjectPutPreconditions evaluates if-match and if-none-match preconditions for object PUT(PutObject, CompleteMultipartUpload) actions

func EvaluatePreconditions added in v1.0.18 

func EvaluatePreconditions(etag string, modTime time.Time, preconditions PreConditions) error

EvaluatePreconditions takes the object ETag, the last modified time and evaluates the read preconditions: - if-match, - if-none-match - if-modified-since - if-unmodified-since if-match and if-none-match are ETag comparisions if-modified-since and if-unmodified-since are last modifed time comparisons

func GenerateEtag added in v1.0.14 

func GenerateEtag(h hash.Hash) string

GenerateEtag generates a new quoted etag from the provided hash.Hash

func GetMultipartMD5 

func GetMultipartMD5(parts []types.CompletedPart) string

func IsValidDirectoryName added in v1.0.19 

func IsValidDirectoryName(name string) bool

IsValidDirectoryName returns true if the string is a valid name for a directory

func MkdirAll 

func MkdirAll(path string, uid, gid int, doChown bool, dirPerm fs.FileMode) error

MkdirAll is similar to os.MkdirAll but it will return ErrObjectParentIsFile when appropriate MkdirAll creates a directory named path, along with any necessary parents, and returns nil, or else returns an error. The permission bits perm (before umask) are used for all directories that MkdirAll creates. Any newly created directory is set to provided uid/gid ownership. If path is already a directory, MkdirAll does nothing and returns nil. Any directory created will be set to provided uid/gid ownership if doChown is true.

func MoveFile added in v1.0.13 

func MoveFile(source, destination string, perm os.FileMode) error

ParseObjectRange parses input range header and returns startoffset, length, isValid and error. If no endoffset specified, then length is set to the object size for invalid inputs, it returns no error, but isValid=false `InvalidRange` error is returnd, only if startoffset is greater than the object size

func ParseObjectTags added in v1.0.12 

func ParseObjectTags(tagging string) (map[string]string, error)

ParseObjectTags parses the url encoded input string into map[string]string with unescaped key/value pair

func TrimEtag added in v1.0.11 

func TrimEtag(etag *string) *string

func WalkDir added in v1.2.0 

func WalkDir(fsys fs.FS, root string, fn WalkDirFunc) error

WalkDir walks the file tree rooted at root, calling fn for each file or directory in the tree, including root.

All errors that arise visiting files and directories are filtered by fn: see the fs.WalkDirFunc documentation for details.

The files are walked in lexical order, which makes the output deterministic but requires WalkDir to read an entire directory into memory before proceeding to walk that directory.

WalkDir does not follow symbolic links found in directories, but if root itself is a symbolic link, its target will be walked.

	IfUnmodeSince *time.Time
}

type WalkDirFunc added in v1.2.0 

type WalkDirFunc func(path string, d fs.DirEntry, err error) error

WalkDirFunc is the type of the function called by WalkDir to visit each file or directory.

The path argument contains the argument to WalkDir as a prefix. That is, if WalkDir is called with root argument "dir" and finds a file named "a" in that directory, the walk function will be called with argument "dir/a".

The d argument is the [DirEntry] for the named path.

The error result returned by the function controls how WalkDir continues. If the function returns the special value [SkipDir], WalkDir skips the current directory (path if d.IsDir() is true, otherwise path's parent directory). If the function returns the special value [SkipAll], WalkDir skips all remaining files and directories. Otherwise, if the function returns a non-nil error, WalkDir stops entirely and returns that error.

The err argument reports an error related to path, signaling that WalkDir will not walk into that directory. The function can decide how to handle that error; as described earlier, returning the error will cause WalkDir to stop walking the entire tree.

WalkDir calls the function with a non-nil err argument in two cases.

First, if the initial [Stat] on the root directory fails, WalkDir calls the function with path set to root, d set to nil, and err set to the error from fs.Stat.

Second, if a directory's ReadDir method (see [ReadDirFile]) fails, WalkDir calls the function with path set to the directory's path, d set to an [DirEntry] describing the directory, and err set to the error from ReadDir. In this second case, the function is called twice with the path of the directory: the first call is before the directory read is attempted and has err set to nil, giving the function a chance to return [SkipDir] or [SkipAll] and avoid the ReadDir entirely. The second call is after a failed ReadDir and reports the error from ReadDir. (If ReadDir succeeds, there is no second call.)

The differences between WalkDirFunc compared to path/filepath.WalkFunc are:

  • The second argument has type [DirEntry] instead of [FileInfo].
  • The function is called before reading a directory, to allow [SkipDir] or [SkipAll] to bypass the directory read entirely or skip all remaining files and directories respectively.
  • If a directory read fails, the function is called a second time for that directory to report the error.

type WalkResults 

type WalkResults struct {
	CommonPrefixes []types.CommonPrefix
	Objects        []s3response.Object
	Truncated      bool
	NextMarker     string
}

func Walk 

func Walk(ctx context.Context, fileSystem fs.FS, prefix, delimiter, marker string, max int32, getObj GetObjFunc, skipdirs []string) (WalkResults, error)

	NextMarker          string
	NextVersionIdMarker string
}

func WalkVersions(ctx context.Context, fileSystem fs.FS, prefix, delimiter, keyMarker, versionIdMarker string, max int, getObj GetVersionsFunc, skipdirs []string) (WalkVersioningResults, error)
