Usually this is EPrints::Platform::Unix Which module is used is configured by the {platform} setting in SystemSettings.pm All file and directory names are absolute and joined by the Unix file separator character '/'. =over 4 =cut package EPrints::Platform; use EPrints::SystemSettings; use strict; no strict 'refs'; my $platform = $EPrints::SystemSettings::conf->{platform}; my $real_module = "EPrints::Platform::\u$platform"; eval "use $real_module;"; ##################################################################### =item chmod( MODE, @filelist ) Change the access control on files listed in @filelist to MODE. =cut ##################################################################### sub chmod { return &{$real_module."::chmod"}( @_ ); } ##################################################################### =item chown( $uid, $gid, @filelist ) Change the user and group on files listed in @filelist to $uid and $gid. $uid and $gid are as returned by L<getpwnam> (usually numeric). =cut ##################################################################### sub chown { return &{$real_module."::chown"}( @_ ); } ##################################################################### =item getpwnam( $user ) Return the login-name, password crypt, uid and gid for user $user. =cut ##################################################################### sub getpwnam { return &{$real_module."::getpwnam"}( $_[0] ); } ##################################################################### =item getpwnam( $user ) Return the login-name, password crypt, uid and gid for user $user. =cut ##################################################################### sub getgrnam { return &{$real_module."::getgrnam"}( $_[0] ); } ##################################################################### =item test_uid() Test whether the current user is the same that is configured in SystemSettings. =cut ##################################################################### sub test_uid { return &{$real_module."::test_uid"}( @_ ); } ##################################################################### =item mkdir( $path, MODE ) Create a directory $path (including parent directories as necessary) set to mode MODE. If MODE is undefined defaults to dir_perms in SystemSettings. =cut ##################################################################### sub mkdir { return &{$real_module."::mkdir"}( @_ ); } ##################################################################### =item exec() Executes certain named tasks, which were once (and may be) handled by external binaries. This allows a per-platform solution to each task. (example is unpacking a .tar.gz file). =cut ##################################################################### sub exec { return &{$real_module."::exec"}( @_ ); } 1; =back
