By default, get_from_cache() returns a deep copy of the data structures stored in L1 cache (aka "safe mode"). For extremely big and/or complex data structures (like MARC framework hash-of-hashes-of-hashes returned by GetMarcStructure() ), deep-cloning is currently sub-optimal; this patch addresses that particular issue. It also provides an ability to intermix "safe" and "unsafe" cache feches, in such way that they don't interfere with each other (i.e., eliminating the risk involved with "unsafe" calls possibly compromising further "safe" calls). Test plan: 1) apply patch 2) flush L2 cache if necessary (restart memcached daemon) 3) profile GetMarcStructure() calls before / after patch, e.g. by running some script which calls it often (like catalogue search w/ XSLT processing turned on, etc.) - GetMarcStructure() should be faster than before, in all possible circumstances (eg. 18 msec per call -> 10 msec p/call) 4) after testing, before returning to the master branch, flush L2 cache again (restart memcached daemon) - otherwise all system preferences returned from L2 cache would be suffixed with '-CF0' Signed-off-by: Jonathan Druart <jonathan.dru...@bugs.koha-community.org> -- You are receiving this mail because: You are watching all bug changes. _______________________________________________ Koha-bugs mailing list Koha-bugs@lists.koha-community.org http://lists.koha-community.org/cgi-bin/mailman/listinfo/koha-bugs website : http://www.koha-community.org/ git : http://git.koha-community.org/ bugs : http://bugs.koha-community.org/
