We'll need to send 'frozen' scalar to memcached somehow packaged (e.g. in [ ]), to be able to distinguish if it was originally a scalar or not. And the complex structures in L2 cache will be double-frozen. But the 2nd freeze call (inside Memcached::Fast) should be very cheap - at that stage, this wouldn't be a complex data structure any more. Unless I'm very much mistaken (see comment #20 item 3) a side effect of this will be a performance gain - after this bug, fetching MARC framework with get_from_cache() will take 10 ms instead of 12.5 ms on average, even with Koha::Cache used entirely in the "safe" mode. Win-win situation ;).
Or just append some small flag to the end of each string we store in L2 and strip it on fetching (0: scalar, 1: structure frozen by Storable() freeze, 2: structure frozen by Sereal, 4: undef value etc. ;) - I don't think it will affect performance of caching very small values in any measurable way, and all that double-frozen madness could be scrached then. -- You are receiving this mail because: You are watching all bug changes.
