From f86a23ff537258d36bf8f1876fa7a4bede6673d8 Mon Sep 17 00:00:00 2001 From: Lars Hjemli Date: Sat, 6 Dec 2008 17:38:19 +0100 Subject: Add a 'stats' page to each repo This new page, which is disabled by default, can be used to print some statistics about the number of commits per period in the repository, where period can be either weeks, months, quarters or years. The function can be activated globally by setting 'enable-stats=1' in cgitrc and disabled for individual repos by setting 'repo.enable-stats=0'.

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'.
