Dpkg::Path − some common path handling functions
It provides some functions to handle various path.
get_pkg_root_dir($file)
This function will scan upwards the hierarchy of directory to find out the directory which contains the " DEBIAN " sub-directory and it will return its path. This directory is the root directory of a package being built.
If no DEBIAN subdirectory is found, it will return undef.
relative_to_pkg_root($file)
Returns the filename relative to get_pkg_root_dir($file).
guess_pkg_root_dir($file)
This function tries to guess the root directory of the package build tree. It will first use get_pkg_root_dir(), but it will fallback to a more imprecise check: namely it will use the parent directory that is a sub-directory of the debian directory.
It can still return undef if a file outside of the debian sub-directory is provided.
check_files_are_the_same($file1, $file2, $resolve_symlink)
This function verifies that both files are the same by checking that the device numbers and the inode numbers returned by stat()/lstat() are the same. If $resolve_symlink is true then stat() is used, otherwise lstat() is used.
canonpath($file)
This function returns a cleaned path. It simplifies double //, and remove /./ and /../ intelligently. For /../ it simplifies the path only if the previous element is not a symlink. Thus it should only be used on real filenames.
$newpath = resolve_symlink($symlink)
Return the filename of the file pointed by the symlink. The new name is canonicalized by canonpath().
my $cmdpath = find_command($command)
Return the path of the command if available on an absolute or relative path or on the $PATH, undef otherwise.
