NAME

Ubic::AccessGuard - class which guards simple service operations

VERSION

version 1.38_01

SYNOPSIS

    use Ubic::AccessGuard;

    $guard = Ubic::AccessGuard->new($service); # change effective uid and effective gid to $service->user and $service->group
    undef $guard; # change them back

DESCRIPTION

Ubic::AccessGuard sets effective uid to specified service's user id if neccesary, and restore it back on destruction.

It's usage is limited, because when effective uid is not equal to real uid, perl automatically turns on tainted mode. Because of this, only tainted-safe code should be called when AccessGuard is active. Ubic doesn't start services under this guard, but uses it when acquiring locks and writing service status files.

METHODS

new($service)

Construct new access guard object.

User will be changed into user apporpriate for running $service. It will be changed back on guard's desctruction.
