From ea360dd0538d03d25f512efe2f100beb3e7c2130 Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Thu, 21 Aug 2008 08:40:44 -0700 Subject: [PATCH] Make reflog query '@{1219188291}' act as '@{2008.8.19.16:24:51.-0700}' As we support seconds-since-epoch in $GIT_COMMITTER_TIME we should also support it in a reflog @{...} style notation. We can easily tell this part from @{nth} style notation by looking to see if the value is unreasonably large for an @{nth} style notation. The value 100000000 was chosen as it is already used by date.c to disambiguate yyyymmdd format from a seconds-since-epoch time value. A reflog with 100,000,000 record entries is also simply not valid. Such a reflog would require at least 7.7 GB to store just the old and new SHA-1 values. So our randomly chosen upper limit for @{nth} notation is "big enough". Signed-off-by: Shawn O.
