Subject: [Tarantool-patches] [PATCH luajit v3 0/3] fix math.min/max inconsistencies
Date: Fri, 12 Nov 2021 01:58:20 +0300	[thread overview]
Message-ID: <cover.1636671272.git.m.kokryashkin@tarantool.org> (raw)

math.min()/math.max() could produce different results when compiled.
Previously, these functions did not check for the number of arguments,
which in some situations led to incorrect behavior.

Changes in v2:
- Squashed the commit containing the test with the commit containing the fix
- Added more informative description for the most of the changes

GitHub branch:
https://github.com/tarantool/luajit/tree/fckxorg/gh-6163-min-max

CI:
https://github.com/tarantool/tarantool/tree/fckxorg/gh-6163-min-max
