From 49050a043bf767d370e7288cb6cca0ca21f13404 Mon Sep 17 00:00:00 2001 From: Siddharth Asthana Date: Tue, 20 Dec 2022 11:31:12 +0530 Subject: [PATCH] cat-file: add mailmap support to -s option MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Even though the cat-file command with `-s` option does not complain when `--use-mailmap` option is given, the latter option is ignored. Compute the size of the object after replacing the idents and report it instead. In order to make `-s` option honour the mailmap mechanism we have to read the contents of the commit/tag object. Make use of the call to `oid_object_info_extended()` to get the contents of the object and store in `buf`. `buf` is later freed in the function.
