Carlos O'Donell 87701a58e2 strcoll: Remove incorrect STRDIFF-based optimization (Bug 18589). ... The optimization introduced in commit f13c2a8dff, causes regressions in sorting for languages that have digraphs that change sort order, like cs_CZ which sorts ch between h and i. My analysis shows the fast-forwarding optimization in STRCOLL advances through a digraph while possibly stopping in the middle which results in a subsequent skipping of the digraph and incorrect sorting. The optimization is incorrect as implemented and because of that I'm removing it for 2.23, and I will also commit this fix for 2.22 where it was originally introduced. This patch reverts the optimization, introduces a new bug-strcoll2.c regression test that tests both cs_CZ.UTF-8 and da_DK.ISO-8859-1 and ensures they sort one digraph each correctly. The optimization can't be applied without regressing this test. Checked on x86_64, bug-strcoll2.c fails without this patch and passes after. This will also get a fix on 2.22 which has the same bug.		2015-10-08 16:41:45 -04:00
