From 883d60fa97c6397450fb129634054e0a6101baac Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Mon, 8 Jan 2007 01:59:54 +0100 Subject: [PATCH] Sanitize for_each_reflog_ent() It used to ignore the return value of the helper function; now, it expects it to return 0, and stops iteration upon non-zero return values; this value is then passed on as the return value of for_each_reflog_ent(). Further, it makes no sense to force the parsing upon the helper functions; for_each_reflog_ent() now calls the helper function with old and new sha1, the email, the timestamp & timezone, and the message.
