Raw Blame History

Release X.Y (202?-??-??)

  • A new function builtins.readFileType is available. It is similar to builtins.readDir but acts on a single file or directory.

  • The builtins.readDir function has been optimized when encountering not-yet-known file types from POSIX's readdir. In such cases the type of each file is/was discovered by making multiple syscalls. This change makes these operations lazy such that these lookups will only be performed if the attribute is used. This optimization affects a minority of filesystems and operating systems.
