From: Sergey Bronnikov <sergeyb at tarantool.org>
>From the beginning we haven't use static analysis for Lua source code and
therefore now we have about 32k warnings and errors produced by luacheck. Sure
these issues are not real bugs but fixing them will make source code better and
clear. Aim to fix all of them at once looks insane and perhaps it is not worth
it.
Summary of static analysis:
There were no errors found by luacheck in production source code (src/),
many warnings were fixed in previous commits and non-interested warnings were
supressed using luacheck config.
Lua source code in test/ directory contains both errors and warnings and there
are a lot of them. Some of these warnings were fixed by previous commits and
most part of warnings and errors supressed in luacheck config. Regarding
errors: all found errors belongs to a single error class - "Syntax error"
(E011). All of them have a single root cause - at the of testscases we write
conditions without assignments and it is confuses luacheck. Usually such
conditions used together with asserts, but in our tests we uses reference outputs
instead of asserts.
How-to check:
$ tarantoolctl rocks install luacheck
$ .rocks/bin/luacheck --codes --config .luacheckrc .
Closes #4681
