+=head1 NAME
+
+FS::upgrade_journal - Object methods for upgrade_journal records
+
+=head1 SYNOPSIS
+
+  use FS::upgrade_journal;
+
+  $record = new FS::upgrade_journal \%hash;
+  $record = new FS::upgrade_journal { 'column' => 'value' };
+
+  $error = $record->insert;
+
+  # Typical use case
+  my $upgrade = 'rename_all_customers_to_Bob';
+  if ( ! FS::upgrade_journal->is_done($upgrade) ) {
+    ... # do the upgrade, then, if it succeeds
+    FS::upgrade_journal->set_done($upgrade);
+  }
+
+=head1 DESCRIPTION
+
+An FS::upgrade_journal object records an upgrade procedure that was run 
+on the database.  FS::upgrade_journal inherits from FS::Record.  The 
+following fields are currently supported:
+
+=over 4
+
+=item upgradenum - primary key
+
+=item _date - unix timestamp when the upgrade was run
+
+=item upgrade - string identifier for the upgrade procedure; must match /^\w+$/
+
+=item status - either 'done' or 'failed'
+
+=item statustext - any other message that needs to be recorded
+
+=back
+
+=head1 METHODS
+
+=over 4
+
+=item new HASHREF
+
+Creates a new upgrade record.  To add it to the database, see L<"insert">.
+
+Note that this stores the hash reference, not a distinct copy of the hash it
+points to.  You can ask the object for a copy with the I<hash> method.
+
+=cut
+
+# the new method can be inherited from FS::Record, if a table method is defined
+
+sub table { 'upgrade_journal'; }
+
+=item insert
+
+Adds this record to the database.  If there is an error, returns the error,
+otherwise returns false.
+
+=cut
+
+# the insert method can be inherited from FS::Record
+
+sub delete  { die "upgrade_journal records can't be deleted" }
+sub replace { die "upgrade_journal records can't be modified" }
+
+=item check
+
+Checks all fields to make sure this is a valid example.  If there is
+an error, returns the error, otherwise returns false.  Called by the insert
+and replace methods.
+
+=cut
+
+# the check method should currently be supplied - FS::Record contains some
+# data checking routines
+
+sub check {
+  my $self = shift;
+
+  if ( !$self->_date ) {
+    $self->_date(time);
+  }
+
+  my $error = 
+    $self->ut_numbern('upgradenum')
+    || $self->ut_number('_date')
+    || $self->ut_alpha('upgrade')
+    || $self->ut_text('status')
+    || $self->ut_textn('statustext')
+  ;
+  return $error if $error;
+
+  $self->SUPER::check;
+}

+
+=head1 CLASS METHODS
+
+=over 4
+
+=item is_done UPGRADE
+
+Returns the upgrade entry with identifier UPGRADE and status 'done', if 
+there is one.  This is an easy way to check whether an upgrade has been done.
+
+=cut
+
+sub is_done {
+  my ($class, $upgrade) = @_;
+  qsearch('upgrade_journal', { 'status' => 'done', 'upgrade' => $upgrade })
+}
+
+=item set_done UPGRADE
+
+Creates and inserts an upgrade entry with the current time, status 'done', 
+and identifier UPGRADE.  Dies on error.
+
+=cut
+
+sub set_done {
+  my ($class, $upgrade) = @_;
+  my $new = $class->new({ 'status' => 'done', 'upgrade' => $upgrade });
+  my $error = $new->insert;
+  die $error if $error;
+  $new;
+}
+
+
+=head1 BUGS
+
+Despite how it looks, this is not currently suitable for use as a mutex.
