NAME ^

Setup - Specification for setup module

VERSION ^

version 1.0.4

SPECIFICATION VERSION ^

1.0

SPECIFICATION ^

This is a specification for setup modules. Setup modules are normal Perl modules that live under the Setup:: namespace and contain setup functions. Setup functions are normal Perl subroutines, typically named with setup_ prefix (like setup_file, setup_unix_user, etc.) They are typically used for, well, setting up stuffs, like software installation, system setup, or configuration management.

Setup functions MUST have metadata, as specified in Rinci specification.

Setup function MUST use Log::Any for logging.

Setup functions MUST support transactions, as described in Rinci::Transaction.

Since setup functions might be used in unsetup (uninstallation) of software months or even years after setup (installation), their interface should be stable. During setup, undo actions are recorded in transaction database and might be used years later.

Setup function should log something like this in the check_state phase when in dry-run mode, to give messages to user:

 my $tx_action = $args{-tx_action};
 my $dry_run   = $args{-dry_run};
 if ($tx_action eq 'check_state') {
     ...
     $log->infof("(DRY) Trashing %s ...", $path);
     return [200, "Path $path should be trashed", undef, {undo_actions=>\@u}];
 }

Setup function should log something like this when about to perform action in fix_state phase:

 # example 1: trashing a file
 $log->infof("Trashing %s ...", $path);
 $trash->trash($path);

 # example 2: creating a user
 $log->infof("Adding user %s ...", $user);
 $res = add_user(user=>$user, ...);
