Subject: objectcache: Use newAccelerator() fallback instead of try/catch
X-Git-Tag: 1.31.0-rc.0~10286^2
X-Git-Url: http://git.cyclocoop.org//%22%22.str_replace%28%27%22%27%2C?a=commitdiff_plain;h=f1223f90fd4b3891bcd18fe621e998c4190c8b9b;p=lhc%2Fweb%2Fwiklou.git

objectcache: Use newAccelerator() fallback instead of try/catch

Also remove confusing use of $wgMemc in LoadMonitorMySQL which
should always be the same as wfGetMainCache().
