patch 9.1.0514: Vim9: issue with comparing objects recursively Commit: https://github.com/vim/vim/commit/7b29cc97d6c1450865969d08c5538a40c304593c Author: LemonBoy <thatlemon@gmail.com> Date: Sat Jun 22 17:25:07 2024 +0200 patch 9.1.0514: Vim9: issue with comparing objects recursively Problem: Vim9: issue with comparing objects recursively (Yinzuo Jiang) Solution: only set recursive == TRUE, when called from tv_equal(), not from typeval_compare_object(), refactor code into object_equal() function (LemonBoy) The recursive flag in tv_equal should be set only when the caller is tv_equal, meaning that the comparison depth is > 1. The comparison predicates for other object types are all following this rule, except for the object one, and that may cause some weird issues like causing the max depth limit not to be initialized in some cases. closes: #15076 Signed-off-by: LemonBoy <thatlemon@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
