From 4d01a7fa65c50e817a935396432e199b7a565f53 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Martin=20=C3=85gren?= Date: Sat, 23 Sep 2017 01:34:54 +0200 Subject: [PATCH] pack-bitmap[-write]: use `object_array_clear()`, don't leak MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Instead of setting the fields of rev->pending to 0/NULL, thereby leaking memory, call `object_array_clear(&rev->pending)`. In pack-bitmap.c, we make copies of those fields as `pending_nr` and `pending_e`. We never update the aliases and the original fields never change, so the aliases are not really needed and just make it harder than necessary to understand the code. While we're here, remove the aliases to make the code easier to follow.
