From fb2f3f6c29bad733723152893c5246a756e4cada Mon Sep 17 00:00:00 2001 From: Lars Hjemli Date: Sun, 7 Dec 2008 13:17:21 +0100 Subject: ui-stats: replace 'enable-stats' setting with 'max-stats' The new 'max-stats' and 'repo.max-stats' settings makes it possible to define the maximum statistics period, both globally and per repo. Hence, it is now feasible to allow statistics on repositories with a high commit frequency, like linux-2.6, by setting repo.max-stats to e.g. 'month'.
