From 5dfaf49a5a651d3e8c3552bc2e833312a3671a4f Mon Sep 17 00:00:00 2001 From: Taylor Blau Date: Fri, 20 May 2022 19:17:43 -0400 Subject: pack-mtimes: support writing pack .mtimes files Now that the `.mtimes` format is defined, supplement the pack-write API to be able to conditionally write an `.mtimes` file along with a pack by setting an additional flag and passing an oidmap that contains the timestamps corresponding to each object in the pack.
