Description
typical case is: user clears cache on node A, but cache is not cleared on node B.
Ideal solution would be intra-cluster communication.
Ad interim solution is to warn user that he should run the same script on all nodes in the cluster.
Proof-of-concept code:
function clearItems( $cacheEntries, $cli, $name )
{
if ( !$name )
$name = 'All cache';
$name = $cli->stylize( 'emphasize', $name );
$cli->output( 'Clearing ' . $name . ': ' );
checkPaths( $cacheEntries, false );
$i = 0;
foreach ( $cacheEntries as $cacheEntry )
{
if ( $i > 0 )
$cli->output( ', ', false );
$cli->output( $cli->stylize( 'emphasize', $cacheEntry['name'] ), false );
eZCache::clearItem( $cacheEntry );
if ( !isset( $cacheEntry['is-clustered'] ) || !$cacheEntry['is-clustered'] ) {
$cl = eZClusterFileHandler::instance();
if ( $cl->requiresPurge() )
{
$cli->output("\nNB: this cache is not clustered. You'd better run the script on all nodes");
}
}
++$i;
}
$cli->output();
}
