Hi! Thanks for the fixes! See my comments below,
fixes at the end of the email, and on the branch
(it is np/gh-3914-fix-create-index-v2).

Nothing functional. Just syntax sugar and API consistency. Otherwise
your statement, that we have a tree of structures with terminal nodes,
is false. For other nodes you have _table/index/fk etc suffix, but
drop is just 'entity'. For me it looks odd. The same for rename_entity.

Strictly speaking, your hierarchy of structures is even not a tree -
in your code create_table_def and create_view_def store alter_entity_def,
but do not initialize nor use it.

Additionally, for not named constraints you do not call
alter_entity_def_init nor even create_constraint_def_init - you just
memset all the structure. So your tree in fact is really corrupted and
ill, sorry.

Talking of duplication - each wrapper around drop_entity and
rename_entity would take 11 simple lines:

     struct drop_<term>_def {
             struct drop_entity_def base;
     }

     static inline void
     drop_<term>_def_init(struct drop_<term>_def *def,
                          struct SrcList *parent_name, struct Token *name,
                          bool if_exist)
     {
             drop_entity_def_init(&def->base, parent_name, name, if_exist,
                                  ENTITY_TYPE_<term>);
     }

For compiler it is nothing - functions are inlined, for binary file
as well. For code and naming consistency it is a big deal. IMO. But
probably I should stop teaching here - you can leave it as is in terms
of list entities or listen to my objectives. Anyway you are likely to be a
single maintainer of all of this for a long time.

The only place, where create_constraint_def_init can not be replaced with
a next level term, is a rule "cconsname_parse ::= CONSTRAINT nm(X).". But
you did not answer below why do you need it here.

I see, that you nullify them, but you did not answer my questions. Why
can not you postpone that nullification until a next word is met -
UNIQUE, PK, FK, CK etc? It would allow you to fold
create_constraint_def_init and always use a term def.

What is more, you initialize named constraints twice - first you
nullify them in cconsname_start with memset, and then call
create_constraint_def_init.

I did my own investigation of this matter, and managed to remove
cconsname_start rule, as well as double init. After that I have
cconsname_parse followed by many term constraint rules, and I tried to
figure out why can't we just inline cconsname into terms ccons and
tcons and remove create_constraint_def_init from public. Especially
taking into account that it is not many changes thanks to that:
https://github.com/tarantool/tarantool/issues/3820.

It means, that we could inline 'CONSTRAINT nm(X)' in 8 places only:

     1) "ccons ::= PRIMARY KEY"
     2) "ccons ::= UNIQUE"
     3) "ccons ::= check_constraint_def"
     4) "ccons ::= REFERENCES"

      + the same for tcons.

But then I realized, that cconsname helps us to keep the name
optional. To solve that we need to somehow save nm(X) result until
a terminal constraint is reached, or nullify it. I think, that we
could add struct Token constraint_name to union of alter entities in
struct Parse, and fetch it from there in terminal constraint
definitions (PK, UNIQUE, CK, FK). It is possible, because in such
a case this union's memory is not occupied by create_constraint_def
until term. It will allow us to remove create_constraint_def_init
from public usage. And to close the issue 3820 alongside.

This is what I wanted to hear from you.



Besides, I have some lowlevel comments on the code.

1) Usually we do not pass structures by value, even such small
as struct Token.

2) You've moved struct Token into parse_def.h, but kept its
routines in sqlite3Int.h. Please, move them too. And please,
rebase - 'sqlite3' has already been replaced with 'sql'.

3) Since now and after point 2 we have internal and long functions
in parse_def, I think it is time to introduce parse_def.c and hide
them here.
