These changes should not be done, IMO. Most of our
tests are diff based, and therefore it is ok to write
a statement just to print it. It is not only simpler, but
also allows to print the actual value, if it didn't match
the expected value.
For example, if n_workers becomes not 0, we would see its
actual value in the diff. When we use assert(), we won't
see anything except an error message 'assertion failed'.
I propose to allow writing non-functional statements in
test/ dir.

I'm used to the language that has "smart" assertions that show
content compared by asserts. Like pytest -
https://docs.pytest.org/en/3.0.1/assert.html
Example:
def test_function():
> assert f() == 4
E assert 3 == 4
E + where 3 = f()
> I propose to allow writing non-functional statements in
> test/ dir.
removed previously added asserts

You can't simply drop "self" argument. See [1]. I assume that a change
that doesn't break behaviour is "function(_, cmd)".

Sergey,
Thanks for the patch! I started with this one, since it's simple and I
can point the general issues related to the fix.
I see the following approach to fix the errors and warning found by
luacheck in *Lua sources*:
* If the fix is obvious and simple -- please do it.
* If the warning/erro fix leads to code complication or reduce
readability (e.g. empty if branch) -- let's add an inline ignore
comment, since it unlikely to be fixed and just burdens .luacheckrc.
* If none of the above -- add the corresponding rule to .luacheckrc.
I left inline comments for your patch and added the fix I made for
tarantoolctl at the end. Please consider them.

Minor: I looked at the code nearby and it looks like this initialization
can be moved below, since udir is unused prior it (consider the changes
below).

Side-note: I see you reverted this change, but the fix proposed by Oleg
is a good one. I guess we can apply it here.

I tried to fix the issues by myself and dumped my step-by-step activity
below. At first let's see what luacheck reports for tarantoolctl source:
| $ luacheck --codes extra/dist/tarantoolctl.in | tail -1
| Total: 35 warnings / 0 errors in 1 file
| $ luacheck --codes extra/dist/tarantoolctl.in | \
| grep -vP '^(Total:|Checking|$)' | cut -f 6 -d ' ' | sort | uniq -c
| 1 (W112)
| 5 (W113)
| 1 (W122)
| 2 (W211)

According to the list of warnings[1] W113 is reported when accessing an
undefined global variable is detected. At the same time W112 is reported
when mutating an undefined global variable is detected. Considering
output these are well known Tarantool globals: box and _TARANTOOL. Let's
suppress them (now with CLI option and globally in .luacheckrc further):
| $ luacheck --codes extra/dist/tarantoolctl.in --globals box --globals _TARANTOOL | \
| grep -vP '^(Total:|Checking|$)' | cut -f 6 -d ' ' | sort | uniq -c

| 4 (W213)
| 3 (W311)
| 2 (W411)
| 13 (W431)
| 1 (W542)
Well, 6 false-positive warnings are suppressed, 29 others left. Let's
see the remaining ones:

| Total: 29 warnings / 0 errors in 1 file
Considering your patch you've already fixed all W211[unused local
variable], W212[unused argument] (considering the fix proposed by Oleg)
and W213[unused loop variable] warnings. The fixes are obvious and
good. Furthermore, you've successfully fixed all W311[value assigned to
a local variable is unused] warnings (but I fixed one of them in a
slightly different way below).
If I didn't miss anything, only the following warnings are left:
| $ luacheck --codes extra/dist/tarantoolctl.in --globals box --globals _TARANTOOL | \
| grep -vP '^(Total:|Checking|$)' | cut -f 6 -d ' ' | sort | uniq -c
| 1 (W122)
| 1 (W411)
| 13 (W431)
| 1 (W542)
* extra/dist/tarantoolctl.in:136:22: (W411) variable 'msg' was previously defined on line 130
Both msg values are well-localized, so I guess we can simply rename
both occurences (consider the changes below).
* extra/dist/tarantoolctl.in:865:59: (W542) empty if branch
This warning is also false-positive, since the way the branches are
organized makes code clearer. Thereby this warning looks unlikely to
be fixed, so I added an inline suppression.
The remaining errors (read-only arg table modification and upvalue
shadowing) can be placed to .luacheckrc to be fixed in future, since
fixes seem to be non-trivial and some of them introduce changes to
function contracts/behaviour.
Omitting few lines to be added to .luacheckrc, here are my changes:

To: tarantool-patches; +Cc: o.piskunov
From: Sergey Bronnikov <sergeyb@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

Hi Sergey, thank you for the patch. As I understood from the comments there are no actual issues blocked in the exclusions for which the new issue should be created and commented into the code, if so, then LGTM.

1. So you disabled that warning for tests, right? Then why still many
statements in the test/ dir are replaced with assertions in one of the
previous commits?

2. In tap tests there is no print of every line's statement.
So if there is a warning about an unused statement in a tap
test, it should be ok to remove/fix it.

3. Please, add test/var too. When tests are run, they leave lots
of lua files in there, which are copied from ignored folders, but
they become not ignored in test/var.

4. Shouldn't that disable 212 and 122 for all lua files? If so,
then why still 122 is mentioned in the lists below? (Not counting
tarantoolctl.in, it does not have .lua suffix).

5. I see that you added some folders to 'exclude_files'. Why is it still
needed to add files from these folders here?

My original goal was following: fix dangerous warnings and supress other
of them per file. I followed this strategy and then discovered that E011
cannot be supressed. In case of errors you should fix them or disable
checking at all for highlighted files/directories. So this is a reason
why some exclusions contains single file and some of them contains file
mask. I decided to keep it as is because more specific supressions are
more convenient to fix when.

Enabled app-tap directory back and keep only test/app-tap/lua/serializer_test.lua
due to error E011: test/app-tap/lua/serializer_test.lua:254:18: (E011) expected expression near 'М'
No idea how to fix it.

I still think, that if a whole folder was ignored in exclude_files, then
it does not make sense to add individual files from this folder again.
Anyway we won't be able to maintain warning ignorance for these files,
because they are just invisible for luacheck.
But I will leave it to a second reviewer. Igor wanted to take a look too.

Do we really need the separate stage for this job ? As we agreed with A. Turenko before, we create stages only for jobs that needs additional steps w/o next steps wont work and which can be used in the next stage for more than single job.
Anyway separate stage will add depends for the rest of the jobs, which can be blocked because of any issue with luacheck, like it can be luacheck cloning either its depends installations:
Installing http://rocks.tarantool.org/luacheck-scm-1.rockspec

This target is common wide along all the jobs and if ENABLE_DIST define is not adding changes for them may be just need add the comment the purpose on its adding.

This target is common wide along all the jobs and may be it better to move the installation to the target ‘luacheck’ which only needs it.

I think the answer is "yes". The arguments are:
- it is a best practice in industry to split CI/CD pipeline for several
stages. In canonical example they are: build, test, deploy.
- build, static analysis, unit testing, module testing are successive
steps in finding bugs. Each step requires different amount of efforts to
debug in case of failure. No reasons to perform unit testing when compiler
warns about non-initialized variables and no reasons to perform complex
functional testing when unit tests failed.
We have future plans to add clang-analyzer and more strict warnings in
compilers and 'static_analysis' stage will be a good place for these
tasks on pipeline.

Actually right that canonical way is good, but do we really need it. Is
it actually better than have the faster way to find the issues? I mean
that out gitlab-ci is using for now not for the automate production, but
for the fast developers testing — it means that they use it not to check
the final code, but to develop it and run it a lot of times during it. I can
absolutely agree that we need CI/CD process and we can start create
it here, but it should be the other separate pipeline from branches
testings. So my suggestion is to left the branch testing flat to be fast,
and add your change just for releases branches testings. By the way
gitlab-ci is too weak for CI/CD processes — much better to use Jenkins
either other CI/CD tools which can use pipelines in parallel instead of
gitlab-ci which can’t do it.
