From 31c029b146388dbe1eb34498cb1ecdbeeb1b00e6 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Mat=C4=9Bj=20Cepl?= Date: Mon, 13 Oct 2025 09:09:34 +0200 Subject: [PATCH 1/2] fix(spec): correct assertion for metatable with __metatable=nil MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A test case in `spec/inspect_spec.lua` was failing when run with LuaJIT on aarch64. The test checks the behavior of `inspect` on tables with metatables that have the `__metatable` field set. The failure occurred for the case where `__metatable` was set to `nil`. The `inspect` function correctly hides the metatable in this scenario, as `getmetatable` returns `nil`. However, the test was expecting the metatable to be displayed, and with incorrect content, causing the assertion to fail. This commit corrects the failing assertion to expect the correct output from `inspect`, which is an empty table string `'{}'`. This aligns the test with the documented behavior of Lua's `getmetatable` and the current implementation of the library.
