From 1577dc0f7c1326ce59e1e97fad8a0b1e8c826203 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Thu, 29 Aug 2019 21:06:22 +0200 Subject: tree: simplify parse_tree_indirect() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reduce code duplication by turning parse_tree_indirect() into a wrapper of repo_peel_to_type(). This avoids a segfault when handling a broken tag where ->tagged is NULL. The new version also checks the return value of parse_object() that was ignored by the old one.
