Hello,

This patchset introduces Clang formatter rules and applies
them to the src/box/ sources (except for sql/). Diff
consists of about 6.000 insertions which is about 5% of
code base.

Is also adds new rules to cmake:
  - make format-set, to apply Clang formatter
  - make format-check, to check if current format is OK

Finally it adds a new job to gitlab CI's first stage which
fails of Clang format is not OK.

I've prepared corresponding changes for other release
branches and intend to commit all changes together.

Issue https://github.com/tarantool/tarantool/issues/4297
Branch https://github.com/tarantool/tarantool/tree/kyukhin/gh-4297-clang-format-master
CI https://gitlab.com/tarantool/tarantool/-/pipelines/209689550

Kirill Yukhin (5):
  clang-format: guard various declarations
  Add .clang-format for src/box/
  build: add clang-format rules
  gitlab-ci: add code style check
  Apply Clang formatter

Disable clang-formatter for:
- iproto_constants.c
- constants in vy_log.c
- key comparator definitions.
- for field_def's types compatibility

Hi! Thanks for the patch!

I will repeat here what I said in the chat.

На русском, чтоб понятнее получилось.

Тикет был создан, когда команда состояла из стажеров более, чем
на половину. Большая часть из них засылала патчи как будто сдавали
задачки в универе за час до дедлайна. Без стиля кода вообще. Тогда
у патчей было комментариев по 50 штук, большая часть которых -
проблемы со стилем.

Но во-первых, это были далеко не все проблемы. Огромное количество
замечаний было по мелким багам, отсутствию тестов или их бесполезности,
по проблемам с английским, когда текст комментариев был нечитаем, и тд.
Потому даже если бы этот патч появился тогда, теперь я понимаю, что
он бы помог не сильно.

Во-вторых, по поводу аргумента, что это отнимает время ревьюера. Каждый
коммент бросить в письмо отнимает пару секунд, буквально. Авто-форс
стиля не сэкономит времени нисколько. 0 минут на патч он сэкономит. Даже
для самого ужасного патча.

Сейчас качество патчей возросло значительно. По мере роста
опыта стажеров, и когда ушли самые заядлые нарушители. Потому кол-во
стилистических проблем измеряется единицами.

В-третьих, этот патч на форматирование вносит большое количество весьма
и весьма спорных изменений. После которых объективно код читать сложнее,
физически. Смотри далее несколько комментов по самым дебильным местам.
Если ты этим надеешься исправить наши редкие споры про стиль некоторых
выражений, то это не поможет. Теперь мы будем спорить, где надо воткнуть
уродливый коммент для игнора форматтера, чтобы он не сделал код еще хуже.

В-четвертых, это говно придется влить во все ветки, так как иначе будет
невозможно патчи пропушивать вниз по версиям. Так что это испортит
историю еще сиьнее.

В-пятых, это не будет единичное изменение истории. Некоторые
места были сделаны с выравниванием для упрощения изменения и чтения.
Форматтер все эти места херит. См далее комменты. 9 штук.

Подпункт пятого замечания - что будешь делать, когда снова прибежит
какой-нибудь любитель плюсов, и скажет, что надо сделать длину строки 120
символов? Или если решим еще какую-нибудь хрень поменять вроде пробелов
приведениях типов? Снова будет патч на косари строк, чтоб все это
обновить?

Суммируя, патч очень плох, и не делает лучше вообще ничего. Я не понимаю,
зачем это льется.

1. VCLOCK_MAX не используется здесь. Все эти комменты у заголовков бесполезны и
даже иногда вредны. В 99% случаев они вообще устарели, и к реальности отношения
не имеют. Просто удали это, пока эти строки меняешь. Патч может и 6к изменений, но
это не значит, что можно их не смотреть.

2. И что здесь в лучшую сторону изменилось? Что до, что после, выглядит одинаково. И оба
варианта вполне по стилю нашему. Но только теперь надо как-то понимать, что первое не
подходит, иначе будет ебошить CI. Это пиздец как неудобно.

6. Из этого изменения становится очевидно, что вся эта ересь
не ограничится одной порчей истории гита. Это будет повторяться.

Предыдущая версия была специально выровнена с запасом, чтобы можно
было добавлять новые имена, и знать, что они не будут вылезать за
существующие имена. Теперь же если добавить имя на один символ
длиннее, чем APPLIER_FETCHED_SNAPSHOT, то форматтер перехуярит весь
енум, похерив историю снова.

такого кода мне иначе придется очки скоро покупать.

9. Это for-цикл. Он не должен как тело функции форматироваться.

Далее я смотрел только бегло, и там еще дохрена таких же
бесполезных изменений.

* Vladislav Shpilevoy <v.shpilevoy@tarantool.org> [20/10/31 12:00]:

Автоматический форматтер нужен.

Нужно оставить в прошлом уже эту историю с обсуждением стиля
патчей - это просто не стоит того чтобы тратить на это время.

Так работает экосистема сегодня многих новых языков, и это
экономит время.
В python есть black, в go есть go fmt.

Можно начать с того чтобы предложить людям способ подключить
автоформатирование к редактору и добиться того что все новые патчи
соответствуют автоформату.

I won't discuss any of the points, since they all were discussed multiple
times and we all agreed to give it a try.

I've increased penalty for breaking on assignement and now this looks much
better.

This is a fix for breaking the rule of 80 cols. But this hunk reveals significant
flaw in current formatter (even in master branch): it tries to keep function
with its arguements on the same line and only after that done it checks everything
else. It'd be greate to be able to set penalty (low) for breaking on param list
and make the change like this:
-	if (tuple_field_u32(tuple, BOX_PRIV_FIELD_ID, &(priv->grantor_id)) != 0 ||
-	    tuple_field_u32(tuple, BOX_PRIV_FIELD_UID, &(priv->grantee_id)) != 0)
+	if (tuple_field_u32(tuple, BOX_PRIV_FIELD_ID,
+			    &(priv->grantor_id)) != 0 ||
+	    tuple_field_u32(tuple, BOX_PRIV_FIELD_UID,
+			    &(priv->grantee_id)) != 0)
Which reads better for me.

I am not sure. Anyway I think this is not a blocker for having fully automated

This is just yet another place which should be accompanied with
/* clang format [off|on] */. Done.

Formatter want's to align all param lines with first param.
I am not sure, I can fix it.

Unfortunatelly, formatter doesn't care about type of statements.
What is even worse, is that its knobs doesn't allow to discriminate
between logical and non-logical operators.
I can make it nice:
 	return strnindex(coll_icu_case_first_strs + 1, str, len,
-			 coll_icu_case_first_MAX - 1) + 1;
+			 coll_icu_case_first_MAX - 1) +
+	       1;
BUT. The patch will increase by 20% since our practice it to
put logical operators at the end of line, and all those places
will be `fixed` by formatter. E.g.:
-       if (priv_def_create_from_tuple(&priv, tuple) != 0 ||
-           grant_or_revoke(&priv) != 0)
+       if (priv_def_create_from_tuple(&priv, tuple) != 0
+           || grant_or_revoke(&priv) != 0)

After all, having p.3 and p.8 unresolved I guess we cannot proceed
without changes to formatter.

Ok. I will review the whole patch, every single line. Don't push
it beforehand then.

4. On Mac the command is called clang-format. And I don't want to mess with
the paths to make it called clang-format-11. Please, look for the executable
properly and use 'clang-format --version' to detect the version, and fail if
it is less than 11 (in case you want not less than 11).

And while we are here, I ask you to provide more info in the comments why
did you choose version 11, and not an older version, as minimal supported.

Currently I don't see a single word not in the commit message nor in the
comments.

See 268 comments below.

Many of them are about the same problems, but still I skipped a lot more due
to the diff being too huge (even though you easily could split it into parts).

In total: the formatter turns the code into shit. You probably would see that,
if you opened your own patch before sending it. From what I saw, you didn't
look at it. Maybe looked at a couple of diff hunks in the beginning.

As a proof, to those who read it, I propose to look at these comments: 20, 51,
79, 111, 152, 153, 164, 259. It is not all of them, but just a few. Proving that
Kirill does not care. This whole patch is just ticking of the boxes in the
planning table, not related to making things actually better for us.

Also I stick to the points I left in the previous review, on which you didn't
respond properly except that "it is discussed" somewhere without any artefacts
of course. It just proves you have nothing to say.

Besides, I understand, that you don't care and already decided to push it, without
listening to anyone. So I will repeat: if you commit it like this - I quit. At
least for month, or until the end of the quarter. I won't review shit, I won't do
shit, won't answer in the chats. Or more than for quarter, if I will like spending
free time on something except tarantool. Otherwise you don't hear me, it seems.
Maybe that will work.

1. The previous formatting was fine, and now it looks worse. Why did it
wrap the arguments so early? And why did it add 14 chars on the lines
with "strlen()" and "0,". I would understand +1 tab, but 14 chars (1 tab
and 6 spaces) looks ridiculous. It looks not confirming to our style at all,
and is just ugly.

3. We don't declare return type on the same line as a function name. If
there are such places, they violate the style, and probably are just old
code.

20. The formatter clearly has failed its job here, twice.

Firstly, if 'if' has {}, 'else' also should have {}.

Secondly, the comment is misaligned as fuck. And the formatter
didn't do anything.

38. We never write enum names in one line. It is harder to
read, harder to comment, and leads to unnecessary git history
rewrite each time when a new value is added.

function name. In new code. Also function body is always
on a separate line, with {} having their own lines.

57. I already said it for a few places, and will repeat here - the alignment
was correct beforehand. Now addition of any function with name longer than
process1_route will change this whole array, making the diff bigger and
ruining the history.

80. This is one of the ugliest things I saw in this patch.
This whole hunk. Did you actually look at it? I mean in the file.
Not at the diff. It looks like some automatically generated code
not intended to be read by a human.

81. The formatting is wrong. Function names should be on separate
line from return type. Also we don't use +1 tab inside macros.

196. The formatting is inconsistent. Functions vy_worker_f and vy_scheduler_f
stayed not formatted. It seems the formatter does not know what to do with
va_list argument.

205. Extra indentation of \ was used to avoid unnecessary changes
when new longer lines are added. So as not to re-aign all the other
lines. Now you ruined it.

Now it not only will change when a new line is added, but also the
entire block now is misaligned in some lines. Mostly due to the
formatter not being able to format operator ?.

In my previous e-mail I've explicitly stated that current formatter
is not suitable for us. Quote:

Please, see what does it mean here [1].

Ok, lets play quotes. Here is yours:

	I am not sure. Anyway I think this is not a blocker for having fully automated
	code formatting.

Talking of this quote:

	After all, having p.3 and p.8 unresolved I guess we cannot proceed
	without changes to formatter.

It is not the same as saying that we won't use the formatter. You just said,
you will try to fix review points 3 and 8. Which were not even the worst.
Which leads to the point you are ok with the other issues. Tons of
other issues, as I found in the detailed review. And I am not ok with these
issues.

You understood completely correct. To the moment we cannot use Clang formatter
since it has unresolvable flaws (in p.3 and p.8). But that doesn't mean we
won't use one of code checkers if found them suitable or if Clang formatter
will become better.
Thanks for sharing your `not ok`, all wyou contributions seems very valuable,
however this doesn't seem to be a blocker.
