From: Aryeh Gregor Date: Wed, 1 May 2019 13:56:41 +0000 (+0300) Subject: Make LocalisationCache a service X-Git-Tag: 1.34.0-rc.0~21^2 X-Git-Url: https://git.heureux-cyclage.org/?p=lhc%2Fweb%2Fwiklou.git;a=commitdiff_plain;h=fadd3277f73c8922cea2443a7e6566f54726fbbc Make LocalisationCache a service This removes Language::$dataCache without deprecation, because 1) I don't know of a way to properly simulate it in the new paradigm, and 2) I found no direct access to the member outside of the Language and LanguageTest classes. An earlier version of this patch (e4468a1d6b6) had to be reverted because of a massive slowdown on test runs. Based on some local testing, this should fix the problem. Running all tests in languages is slowed down by only around 20% instead of a factor of five, and memory usage is actually reduced greatly (~350 MB -> ~200 MB). The slowdown is still not great, but I assume it's par for the course for converting things to services and is acceptable. If not, I can try to optimize further.
