func NewPathFilter

func NewPathFilter(allowedPrefixes []string, allowedPaths []string, disallowedPrefixes []string, disallowedPaths []string) PathFilter

NewPathFilter factory function for a tree-based PathFilter `nil` and empty arrays are treated in a different way. The PathFilter will not perform checks associated with a `nil` array, examples:

  • `allowedPrefixes` & `allowedPaths` are nil -> all paths are allowed (unless included in `disallowedX` arrays)
  • `allowedPrefixes` & `allowedPaths` are both empty -> no paths are allowed, regardless of what is inside `disallowedX` arrays
  • `allowedPrefixes` is nil, `allowedPaths` is not nil. -> only paths specified in `allowedPaths` are allowed (unless included in `disallowedX` arrays)

type UpsertFileCommand struct {
	Path               string
	MimeType           string

	// Contents of an existing file won't be modified if cmd.Contents is nil
