[tarantool-patches] Re: [PATCH v9] sql: add index_def to struct Index

Firstly, I have found some bugs:
tarantool> create table t1(a,b,c,d, primary key(a,a,a,b,c));
---
...
It is OK, but when I do this:
tarantool> create index i1 on t1(b,c,a,c)
---
...
tarantool> create index i1 on t1(b,c,a,c)
---
...
tarantool> create index i1 on t1(b,c,a,c)
---
…
No error is raised and index isn’t created.
After you find and fix this bug, add also test on this case.
Then:
CREATE TABLE t11 (s1 INT, a, constraint c1 UNIQUE(s1) on conflict replace, PRIMARY KEY(s1));
In this case creation of unique constraint c1 is omitted, but no errors or warnings are shown.
It is not a problem now, but when ALTER TABLE DROP CONSTRAINT is implemented,
it will be possible to drop c1 constraint. Eventually, user would be disappointed if tried to drop
this constraint but got an error.

Use uint32_t instead of int:
- int pk_part_count = (int) pPk->def->key_def->part_count;
+ uint32_t pk_part_count = pPk->def->key_def->part_count;

Why do you need to construct “CREATE INDEX” statement from scratch?
This function is only called from sql_create_index() - there you already have
this string:
/*
* Gather the complete text of the CREATE INDEX
* statement into the zStmt variable
*/
assert(start != NULL);
int n = (int)(parse->sLastToken.z - token->z) +
parse->sLastToken.n;
if (token->z[n - 1] == ';')
n--;

Instead of checking table on NULL in each branch and after that using assert(table != NULL),
it is better to replace that assert() with check:
- if (table == NULL)
- goto exit_create_index;
- sqlite3PrimaryKeyIndex(table);
} else {
assert(token == NULL);
assert(start == NULL);
table = parse->pNewTable;

Look, you don’t need to find max_iid: if it is parsing stage, then you can
set it to any meaningful value (since in the end of function it is going to be destroyed);
if it is executing step, you can use db->init.newTnum.
