build.hashers.apenwarr

Special meaning of keys?

No, but they must have an associated file name.

This hasher is like the build.hashers.mtime hasher but it not only keeps track of the modification time, but also the inode, file size, owner and group, etc. More details can be found at the article mtime comparison considered harmful.

Usage

local Hasher = require "build.hashers.apenwarr" (Posix_File_System, File_Of_Key)
local hasher = Hasher.create(posix_file_system)

• Posix_File_System must be the POSIX file system structure to use.
• File_Of_Key must be a function that will be called like File_Of_Key(key). It must return the filename of the file associated with the key, or nil if the key has no filename.
• posix_file_system must be the Posix_File_System instance to use.

Notes

Same note from the mtime rebuilder about file-less keys applies here.
