From 38849a8116e690071c02eba0a8ef60a031a58080 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Tue, 6 Oct 2015 15:18:34 +0200 Subject: [PATCH] sha1_file.c: add a function to release all packs On Windows, files that are in use cannot be removed or renamed. That means that we have to release pack files when we are about to, say, repack them. Let's introduce a convenient function to close all the pack files and their idx files. While at it, we consolidate the close windows/close fd/close index stanza in `free_pack_by_name()` into the `close_pack()` function that is used by the new `close_all_packs()` function to avoid repeated code.
