As our experience has been considered by the maintainer of lua-Harness
and the issues we faced are finally fixed in mainline repo, we should
bump lua-Harness suite up to c4451fe0.

Part of tarantool/tarantool#5970
Part of tarantool/tarantool#4473

---
Changes in v2:
  - Fixed comments as per review by Igor Munkin <imun@tarantool.org>
  - Backported two more fixes from trunk
  - Disabled 241-standalone.t as it is facing some issues to run 
    properly on FreeBSD (for more information see
    tarantool/tarantool#6231)

Backports conversion to Test.Assertion patch[1] from lua-Harness suite

As a result out of this change out-of-source testing is broken, but the
previous assertion using package.path as a second argument worked fine.
Because of that, this commit includes fix, that was made by this patch[2]
in mainline lua-Harness.

In scope of this patch[1] from lua-Harness assertion module tap.lua is
renamed to test_assertion.lua to avoid name collision with Tarantool
tap builtin module.

In scope of the commit 45ed138dcb9228d8ac5b8d82331ddd20a0bfada1
('test: set USERNAME env var for lua-Harness suite') the environment
of the testing process is tweaked via CMake, since both LOGNAME and
USERNAME environment variables might be missing.

Actually, POSIX standard states that every user must have HOME
environment variable set. It allows to use this in the corresponding
assertion instead of LOGNAME and USERNAME without additional
environment setup.

As a result this patch[1] from lua-Harness suite supersedes the
mentioned commit, and CMake hack can be dropped.

The patch[1] from lua-Harness suite fixes the same issue commit
837688590919fcf8de47ef90479fd2a640c8fddc ('test: adjust lua-Harness
suite to CMake machinery') does except the single difference:
`get_lua_binary_name()` is called `_retrieved_progname()`. As a result
of this patch the function is renamed to follow the original naming.

The patch[1] from lua-Harness suite is quite similar to commit
d11c5bbc08a118b11167c5d455d4024607dab662 ('test: adjust lua-Harness
tests that use dofile'), with the one difference (except the naming):
`make_specific_checks()` provides the particular behaviour to run the
tests for out-of-source build, however `_dofile()` allows user to
overload this function considering his purposes. If user leave
`_dofile()` untouched, it defaults to `dofile()` Lua standard library
function.

It's worth to mention, that LuaJIT testing machinery has been using
such approach since commit 734cc0f1d508429c2c3c46bd1860398db0051060
('test: adapt PUC-Rio suite for out-of-source build') and `_dofile()`
behaviour for running tests when out of source build is used is
already defined in luajit-test-init.lua.

The patch[1] from lua-Harness fixes the same issue commit
789820aac7cecc3b5ae394aadc12a5ec25b68121('test: fix directory detection
in lua-Harness suite') does, but it also works on Windows, so the
mentioned commit can be supreseded by that patch.

The patch[1] from lua-Harness suite adds some specific checks to
lua-Harness tests, so they are compatible with Tarantool now.

Considering this, commit d4e12d7ac28e3bc857d30971dd77deec66a67297('test:
disable LuaJIT CLI tests in lua-Harness suite'), which disabled
tarantool cli tests, can be superseded.

As a result, the introduced assertion for Tarantool error message fails
on MacOS, since getopt_long(3) yields the error message without single
quotes wrapping the flag. Hence, this commit also includes fix for that
from patch[2] in the trunk.

This patch backports several small commits from lua-Harness suite:
- follow ravi 1.0-beta4[1]
- refactor with near[2]
- follow LuaJIT[3]
- fix when no debug[4]
- check if luac exists[5]
- https[6]
- more assert[7]

Tarantool interactive mode misbehaviour has been found on FreeBSD (for more info see #6231).
Hence, this particular assertion is masked for FreeBSD until the mentioned issue resolves.

Resolves #5970
Part of #4473

Max,

Thanks for the series! Please consider the comments I left for each
patch. Besides, to differ the patches for tarantool/tarantool repo from
the patches for tarantool/luajit repo, please use 'luajit' in subject
prefix when formatting the patch (consider this patch[1] as an example).

It's more convenient to share the commit that triggered Tarantool CI. In
your case this is https://github.com/tarantool/tarantool/commit/344c18d.

Minor: You can strip commit hash in the links above up to 7 symbols to

Max,

Thanks for the patch! The changes are fine, so no comments regarding
them, but please consider the nit regarding the commit message.

On 20.07.21, Maxim Kokryashkin wrote:

Please, describe the changes in details. E.g. it's worth to mention that
this patch introduces lua-Harness profile for Tarantool considering the
platform specifics. Furthermore, these changes skips all CLI-related
tests for Tarantool binary, so 241-standalone.t and 411-luajit.t can be
renamed back.

Strictly saying, no *new* checks are *added*, but the *existing* ones
are *adjusted* considering Tarantool specifics.

No, it can't. The mentioned commit is superseded by "[PATCH v2 06/10]
test: support tarantool in lua-Harness" in this series.

Minor: 7 digits are enough. This is not critical, but just odd to have
two similar links with the different number of digits, so feel free to
ignore this nit.

The changes from the latter commit is missing.

Furthermore, you've updated lua-Harness up to c4451fe, which is
backported in scope of "[PATCH v2 01/10] test: port lua-Harness to
Test.Assertion". Hence, the commit subject need to be updated too.

>

BTW, both issues are also mentioned the wrong way. The right format is
tarantool/tarantool#<issue-number> for both cases (see the previous
patches in the series for the examples).

Max,

Thanks for the patch! Please consider the comments below.

At first, commit subject exceeds 50 symbols and the message exceeds 72
symbols. Please check this patch against our guidelines[1].

On 20.07.21, Maxim Kokryashkin wrote:

The issue is mentioned the wrong way. The right format is
tarantool/tarantool#6231.

> Hence, this particular assertion is masked for FreeBSD until the mentioned issue resolves.

Strictly saying, you skipped all assertions (not only those using broken
interactive mode), not the particular one.

> 
> Resolves #5970

This patch doesn't resolve the issue, since Tarantool profile introduced
in "[PATCH v2 06/10] test: support tarantool in lua-Harness" is not used
by Tarantool CI. Hence this is only "Part of" patch.

> Part of #4473

BTW, both issues are also mentioned the wrong way. The right format is
tarantool/tarantool#<issue-number> for both cases (see the previous
patches in the series for the examples).

It's also worth to add "Relates to tarantool/tarantool#6231".

At first, please add a comment with the rationale for this change.
Furthermore, it's better to skip only assertions using interactive mode
and run other assertions related to CLI behaviour.

Thanks for the review, Igor!
Here is the new commit message with your suggestions in mind:
==========================================================
    test: port lua-Harness to Test.Assertion
    Backports conversion to Test.Assertion patch[1] from lua-Harness suite.
    As a result of this change out-of-source testing is broken, but the
    previous assertion using package.path as a second argument worked fine.
    Because of that, this commit includes fix, that was made by this patch[2]
    in mainline lua-Harness.

Thanks for the review, Igor!
Here’s the new commit message with all changes made:
===============================================
    test: support tarantool in lua-Harness
    Backports 'support Tarantool' patch[1] from lua-Harness.
    This patch introduces lua-Harness profile for Tarantool considering the
    platform specifics. Furthermore, these changes skip all CLI-related
    tests for Tarantool binary, so 241-standalone.t and 411-luajit.t can be
    renamed back.

    Part of tarantool/tarantool#5970
    Part of tarantool/tarantool#4473

Thanks for the review, Igor!
Here is the new commit message, considering your comments:
=================================================
    test: support tarantool cli in lua-Harness
 
    The patch[1] from lua-Harness suite adjusts some checks in
    lua-Harness tests, so they are compatible with Tarantool now.
 
    As a result, the introduced assertion for Tarantool error message fails
    on MacOS, since getopt_long(3) yields the error message without single
    quotes wrapping the flag. Hence, this commit also includes fix for that
    from patch[2] in the trunk.

    test: disable 241-standalone.t on FreeBSD
 
    Tarantool interactive mode misbehaviour has been found on
    FreeBSD (for more info see tarantool/tarantool#6231). Hence, this[1]
    particular assertion is masked for FreeBSD until the mentioned issue
    resolves.

Nit: Feel free to drop a comment here why this part is disabled for
FreeBSD (maybe with FIXME or XXX label).

Nit: Strictly saying the patch disables only interactive mode part with
input from the file.

Hi, Maxim!

Thanks for the patch!
LGTM except a few nits regarding to the commit message.

===================================================================
    test: use CI friendly variables in lua-Harness

    In scope of the commit 45ed138dcb9228d8ac5b8d82331ddd20a0bfada1

Typo: s/In scope/In the scope/

    ('test: set USERNAME env var for lua-Harness suite') the environment
    of the testing process is tweaked via CMake, since both LOGNAME and
    USERNAME environment variables might be missing.

    Actually, POSIX standard states that every user must have HOME
    environment variable set. It allows to use this in the corresponding

Typo? s/this/this variable/

    assertion instead of LOGNAME and USERNAME without additional
    environment setup.

    As a result this patch[1] from lua-Harness suite supersedes the
    mentioned commit, and CMake hack can be dropped.

Typo: s/CMake hack/the CMake hack/

Hi, Max!

Thanks for the patch!

LGTM, except several nitpicks regarding the commit message:
===================================================================
    test: refactor with _retrieve_progname

    The patch[1] from lua-Harness suite fixes the same issue commit

Typo: /from lua-Harness suite/from the lua-Harness suite/
Typo: /commit/as the commit/

    837688590919fcf8de47ef90479fd2a640c8fddc ('test: adjust lua-Harness
    suite to CMake machinery') does except the single difference:
    `get_lua_binary_name()` is called `_retrieved_progname()`. As a result
    of this patch the function is renamed to follow the original naming.

Hi, Maxim!

Thanks for the patch!
LGTM, except the nitpick regarding the commit message.

Side note: I suppose the same comment should be added in the Tarantool's

Hi, Maxim!

Thanks for the patch!

Please consider my comments below.

Nit: s/tarantool/Tarantool/.

|
| Backports 'support Tarantool' patch[1] from lua-Harness.

Nit: s/Tarantool/tarantool/ regarding to the original commit message.

| This patch introduces lua-Harness profile for Tarantool considering the
| platform specifics. Furthermore, these changes skip all CLI-related
| tests for Tarantool binary, so 241-standalone.t and 411-luajit.t can be
| renamed back.

I afraid, not so fast. Within these changes tests are failed in the
LuaJIT's repo with the following error:
|! unknown luaJIT command or jit.* modules not installed

Seems like LUA_PATH should be adjusted for these tests.

Thanks for the review, Sergey!
New commit message, with your comments in mind:
=================================================================
    test: port lua-Harness to Test.Assertion
 
    Backports conversion to Test.Assertion patch[1] from the
    lua-Harness suite.
 
    As a result of this change out-of-source testing is broken, but the
    previous assertion using package.path as a second argument worked fine.
    Because of that, this commit includes fix, that was made by this
    patch[2] in the mainline lua-Harness.

Thanks for the review, Sergey!
Here is the new commit message, considering your comments:
====================================================================
    test: use CI friendly variables in lua-Harness
 
    In the scope of the commit 45ed138dcb9228d8ac5b8d82331ddd20a0bfada1
    ('test: set USERNAME env var for lua-Harness suite') the environment
    of the testing process is tweaked via CMake, since both LOGNAME and
    USERNAME environment variables might be missing.
 
    Actually, POSIX standard states that every user must have HOME
    environment variable set. It allows to use this variable in
    the corresponding assertion instead of LOGNAME and USERNAME without
    additional environment setup.
 
    As a result this patch[1] from lua-Harness suite supersedes the
    mentioned commit, and the CMake hack can be dropped.

Thanks for the review, Sergey!
Here is the new commit message:
====================================================================
    test: refactor with _retrieve_progname
 
    The patch[1] from the lua-Harness suite fixes the same issue as commit
    837688590919fcf8de47ef90479fd2a640c8fddc ('test: adjust lua-Harness
    suite to CMake machinery') does except the single difference:
    `get_lua_binary_name()` is called `_retrieved_progname()`. As a result
    of this patch the function is renamed to follow the original naming.

Thanks for the review, Sergey!
Here is the new commit message, with your comment in mind:
=============================================================
    test: refactor with _dofile
 
    The patch[1] from the lua-Harness suite is quite similar to commit
    d11c5bbc08a118b11167c5d455d4024607dab662 ('test: adjust lua-Harness
    tests that use dofile'), with the one difference (except the naming):
    `make_specific_checks()` provides the particular behaviour to run the
    tests for out-of-source build, however `_dofile()` allows user to
    overload this function considering his purposes. If user leave
    `_dofile()` untouched, it defaults to `dofile()` Lua standard library
    function.
 
    It's worth to mention, that LuaJIT testing machinery has been using
    such approach since commit 734cc0f1d508429c2c3c46bd1860398db0051060
    ('test: adapt PUC-Rio suite for out-of-source build') and `_dofile()`
    behaviour for running tests when out of source build is used is
    already defined in luajit-test-init.lua.

    Part of tarantool/tarantool#5970
    Part of tarantool/tarantool#4473
=============================================================
 
As for your side note, I’ll add the requested comment to the tarantool repo along with
the luajit bump commit later on.

Here is the new commit message:
==================================================================================
    test: support Tarantool in lua-Harness
 
    Backports 'support tarantool' patch[1] from lua-Harness.
    This patch introduces lua-Harness profile for Tarantool considering the
    platform specifics. Furthermore, these changes skip all CLI-related
    tests for Tarantool binary, so 241-standalone.t and 411-luajit.t can be
    renamed back.

Hi, Maxim!

Thanks for the fixes!

My bad, didn't check it before:

When building out-of-source build and run tests, 411 test still failed,
because LUA_PATH doesn't include path to generated <jit/vmdef.lua>.

Please add path to it in the <CMakeLists.txt>.

| module 'jit.vmdef' not found:
|         no field package.preload['jit.vmdef']
|         no file './jit/vmdef.lua'

Nit: Also you may adjust those comment about required files.

Hi, Maxim!

LGTM, except a single nitpick regarding the commit message.

Max,

Thanks for the fixes! Just my two cents for the change below.

We try to box our comments up to 66 symbols. This is not a strict rule
anymore, but if you can follow this, please do. Feel free to ignore.

> +set(LUA_PATH "./?.lua\;${CMAKE_CURRENT_SOURCE_DIR}/?.lua\;${LUAJIT_SOURCE_DIR}/?.lua\;${CMAKE_BINARY_DIR}/src/?.lua")

There is LUAJIT_BINARY_DIR variable, so please use either both
LUAJIT_*_DIR or CMAKE_*_DIR/src for consistency. BTW, consider the
difference between CMAKE_*_DIR and PROJECT_*_DIR, so I'm sure you need
the latter one.

Hi! Thanks for the review, Sergey!
Here is the new commit message, considering your comments:
======================================================
    test: support tarantool cli in lua-Harness
 
    The patch[1] from the lua-Harness suite adjusts some checks in
    the lua-Harness tests, so they are compatible with Tarantool now.
 
    As a result, the introduced assertion for Tarantool error message fails
    on MacOS, since getopt_long(3) yields the error message without single
    quotes wrapping the flag. Hence, this commit also includes the fix for
    that from the patch[2] in the trunk.

Here is the diff, which adds a comment explaining the reason why the

    Tarantool interactive mode misbehaviour has been found on

    particular assertion is masked for FreeBSD until the mentioned issue
    resolves.

Max,

Surprisingly, I haven't given LGTM for this one, and that's reasonable
(luckily). The test still fails on FreeBSD[1] since there are others
tests with interactive mode. I've fixed the remaining issue, so your
patch[2] looks the following way:

    test: disable interactive mode assertions on BSD

    Tarantool interactive mode misbehaviour has been found on
    FreeBSD (for more info see tarantool/tarantool#6231). Hence, all
    assertions using interactive mode are skipped on FreeBSD until the
    mentioned issue is resolved.

    Resolves tarantool/tarantool#5970
    Part of tarantool/tarantool#4473
    Relates to tarantool/tarantool#6231

CI is green now[3], so LGTM for this one and I'll push your patchset to
the trunk in a jiffy.

I also changed "Part of tarantool/tarantool#5970" back to "Resolves
tarantool/tarantool#5970". I'll move Tarantool profile integration to a
separate issue, so we can close this one.

Max,

I've checked the patchset into all long-term branches in
tarantool/luajit and bumped a new version in 1.10, 2.7, 2.8 and master.
