From d44e5267eaefb27521e4ed2655358b0282add239 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Sat, 14 Nov 2020 19:37:03 +0100 Subject: [PATCH] diff-lib: plug minor memory leaks in do_diff_cache() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit do_diff_cache() builds a struct rev_info to hand to diff_cache() from scratch by initializing it using repo_init_revisions() and then replacing its diffopt and prune_data members. The diffopt member is initialized to a heap-allocated list of options, though. Release it using diff_setup_done() before overwriting it. The initial value of the prune_data member doesn't need to be released, but the copy created using copy_pathspec() does. Clear it after use.
