NAME
Dpkg::Path - some common path handling functions
DESCRIPTION
It provides some functions to handle various path.
METHODS
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 defined and available on an absolute or relative
path or on the $PATH, undef otherwise.
my $control_file = get_control_path($pkg, $filetype)
Return the path of the control file of type $filetype for the given package.
my @control_files = get_control_path($pkg)
Return the path of all available control files for the given package.
my $file = find_build_file($basename)
Selects the right variant of the given file: the arch-specific variant
("$basename.$arch") has priority over the OS-specific variant ("$basename.$os")
which has priority over the default variant ("$basename"). If none of the files
exists, then it returns undef.
my @files = find_build_file($basename)
Return the available variants of the given file. Returns an empty list if none of
the files exists.
