NAME
Dpkg::Path - some common path handling functions
DESCRIPTION
It provides some functions to handle various path.
FUNCTIONS
- 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().
- $cmdpath = find_command($command)
-
Return the path of the command if defined and available on an absolute or relative path or on the $PATH, undef otherwise.
- $control_file = get_control_path($pkg, $filetype)
-
Return the path of the control file of type $filetype for the given package.
- @control_files = get_control_path($pkg)
-
Return the path of all available control files for the given package.
- $file = find_build_file($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 ("$basename"). If none of the files exists, then it returns undef.
- @files = find_build_file($basename)
-
Return the available variants of the given file. Returns an empty list if none of the files exists.
