Subject: [Tarantool-patches] [PATCH luajit v3 22/29] test: disable PUC-Rio test for fast function name
Date: Tue, 13 Apr 2021 16:27:22 +0300	[thread overview]
Message-ID: <521301d79ff90b6dd9b7a5bc345f84a31540c1a3.1618320000.git.skaplun@tarantool.org> (raw)
In-Reply-To: <cover.1618320000.git.skaplun@tarantool.org>

When LuaJIT tries to detect function's name for error message, it
determines the bytecode position first, via `debug_framepc()`. For
tailcall there is no creation of additional Lua frame, so the current
frame is a C protected frame (at the moment of the error throwing).
`debug_framepc()` can't determine bytecode position for non-Lua frames,
so the fast function name is not detected.

This patch disables the test that checks the name of built-in functions
reported in error in tail call.
