I have no idea, how, to fit it in our architecture.
OP_Column has no intersections with binding machinery.
Fire CK constraints for LUA spaces.
To achieve this goal, we reworked data dictionary, to store ck
constraints in separate space _ck_constraints and updated data
migration script to migrate existent data there. This also would
be useful in future to implement ALTER SPACE ADD CONSTRAINT
operation. Now we do not support CK constraint creation on
non-empty space.
Each CK has own precompiled VDBE machine that performs this
check with tuple fields mapped to it's memory with sql_bind() api.
In case of ck constraint conflict detected by this VM we abort
the transaction and return error to user.
Finally, we introduced a LUA-wrapper that provide a user-friendly
way to manage space ck constraints.
Changes in version 2:
- some path parts has been already merged in master
- dropped commits "box: fix _trigger and _ck_constraint
access check" and "sql: disallow use of TYPEOF in
Check" because they are not required and simply wrong
- code rebased on actual master
- reworked ck_constrain_def and ck_constraint structures
and methods to provide a little more consistent API
- reworked structures are used on SQL parse
- new user-friendly API
- use on_replace trigger instead before_replace trigger
to deal with already-validated tuple
- many minor review fixes
- many amazing new test

This patch introduces a new system space to persist check
constraints. Format of the space:
_ck_constraint (space id = 357)
[<constraint name> STR, <space id> UINT,
<is_deferred>BOOL, <expression string>STR]
CK constraint is local to space, so every pair <CK name, space id>
is unique (and it is PK in _ck_constraint space).
After insertion into this space, a new instance describing check
constraint is created. Check constraint holds AST of expression
representing it.
While space features check constraints, it isn't allowed to
be dropped. The :drop() space method firstly deletes all check
constraints and then removes entry from _space.
Because space alter, index alter and space truncate operations
cause space recreation, introduced RebuildCkConstrains object
that compiles new ck constraint objects, replaces and removes
existent instances atomically(when some compilation fails,
nothing is changed). In fact, in scope of this patch we don't
really need to recreate ck_constraint object in such situations
(patch space_def pointer in AST like we did it before is enough
now, but we are going to recompile VDBE that represents ck
constraint in future that can fail).
The main motivation for these changes is the ability to support
ADD CHECK CONSTRAINT operation in the future. CK constraints are
are easier to manage as self-sustained objects: such change is
managed with atomic insertion(unlike the current architecture).
Disabled xfer optimization when some space have ck constraints
because in the following patches this xfer optimisation becomes
impossible. No reason to rewrite this code.
Needed for #3691

To perform ck constraints tests before insert or update space operation,
we use precompiled VDBE machine is associated with each ck constraint,
that is executed in on_replace trigger. Each ck constraint VDBE code is
consists of
1) prologue code that maps new(or updated) tuple fields via bindings,
2) ck constraint code is generated by CK constraint AST.
In case of ck constraint error the transaction is aborted and ck
constraint error is handled as diag message.
Each ck constraint use own on_replace trigger.
Closes #3691

Title: check constraint for Lua space
The check constraint is a type of integrity constraint which
specifies a requirement that must be met by tuple before it
is inserted into space. The constraint result must be predictable.
Expression in check constraint must be <boolean value expression>
I.e. return boolean result.
Now it is possible to create ck constraints only for empty space
having format. Constraint expression is a string that defines
relations between top-level tuple fields.
Take into account that all names are converted to an uppercase
before resolve(like SQL does), use \" sign for names of fields
that were created not with SQL.
The check constraints are fired on insertion to the Lua space
together with Lua space triggers. The execution order of
ck constraints checks and space triggers follows their creation
sequence.
To create a new CK constraint for a space, use
s = box.schema.create_space('person')
_ = s:create_index('pk', {parts = {1, 'string'}})
s:format({{name='name', type='string'}, {name='age', type='integer'},
{name='experience', type='integer'}})
s:ck_constraint({'physics', '\"age\" > 14 and \"experience\" <
\"age\"'})
s:insert({"James Bond", 36, 36})
---
- error: 'Check constraint failed ''physics'': "age" > 14 and
"experience" < "age"'
...
s:insert("James Bond", 36, 16) -- success
s:insert({"Bobby", 6, 0})
---
- error: 'Check constraint failed ''physics'': "age" > 14 and
"experience" < "age"'
...
To list all ck constraints associated with space,
s:ck_constraint()
To replace ck constraint, use following syntax:
s:ck_constraint({'physics', '\"experience\" < \"age\"'}, {'physics'})
s:insert({"Bobby", 6, 0}) -- success
To drop ck constraint, use:
s:ck_constraint(nil, {'physics', '\"experience\" < \"age\"'})

Is there a ticket for adding CHECK constraint on a non-empty
space?
We need to add a general do-any-alter-by-rebuild algorithm so that
all such features work by rebuilding a table. We could optimize
these later.
*No* SQL feature is usable unless DDL related to this feature
works on a non-empty space, at least somehow.

Good.

We can’t we simply do this:
Add to ck_constraint array of used field numbers -
that’s done during ck_constraint_program_compile()
while we have struct Expr by traversing AST. Then,
we emit OP_Variable ck_field_count times, where
ck_field_count is length of array of used field numbers.
Part of code responsible for CK code generation is:
case TK_COLUMN:{
int iTab = pExpr->iTable;
int col = pExpr->iColumn;
if (iTab < 0) {
if (pParse->ckBase > 0) {
/* Generating CHECK constraints. */
return col + pParse->ckBase;
}
So we have to pass that array to parsing context.
Using that array code will look like this:
…
for (int i = 0; i < ck_field_count; ++i) {
if (ck_fields[i] == col)
return ck_fields[i];
}
assert(0);
When it’s time to run program, we go through array
and assign only fields present there:
…
for (int i = 0; i < ck_field_count; ++i) {
sql_bind_decode(&bind, ck_fields[i])
sql_bind_column(...)
}

Please make sure at least the space definition contains all the
fields necessary for information_schema, even if this patch
doesn't fill in some of the fields yet.
Does it? What's in information_schema.check_constraints? What do
other vendors store in this system space (like deferrable,
initially deferred).

I believe I understand how it works now.
What is the problem in fixing it? In scope of this patch set or a
different one is another issue.

Imagine you have stored Lua functions. Don't you want to be able
to define Lua check constraints from Lua?
Which begs a question, should _ck_constraint space contain
'language' field just in case you'd want to add this inthe future?
Looks a bit weird that you use Lua to define an SQL constraint,
doesn't it?
But overall this is pretty cool already.

Not exactly like this, but quite similar(see attachment below).
At first, the bytecode is compiled with vdbe_emit_ck_constraint
based on sqlExprIfTrue encoder. So, this code refers BY FIELDNO
to some fields in memory having the following layout:
[0 X 0 0 X X 0 0 0 0]
So we may bind only min_field_count fields, there the min_field_count
it the fieldno + 1 of the rightmost referenced field.
Actually we may use a bitmap of used fields and bind only them, but
managing such bitmap (that may not fit into uint64_t e.g. in general case)
is costly and there is no difference between binding NULL and field
while we must decode via mp_next all min_field_count tuple fields anyway.

Hello everybody,
The discussion has grown in many threads. I've gathered together
everything that we have agreed and what has been done.
Looks like we have a conception with this patch series with
@korablev now.
I'll resend whole patch a bit later.
(careful: now it is based on kshch/gh-3691-sql-flags-in-parser branch)

Re: [dev] cast 15.05.2019, 21:44
#4216
and decided that it's OK and we should live with it.
I've included the following description in the last commit:
Note: this patch changes the CK constraints execution order for
SQL. Previously check of CK constraints integrity was fired before
tuple is formed; meanwhile now they are implemented as NoSQL before
replace triggers, which are fired right before tuple insertion.
In turn, type casts are performed earlier than msgpack
serialization. You should be careful with functions that use
field types in your check constrains (like typeof()).
Consider following situation:
```
box.execute("CREATE TABLE t2(id INT primary key,
x INTEGER CHECK (x > 1));")
box.execute("INSERT INTO t2 VALUES(3, 1.1)")
```
the last operation would fail because 1.1 is silently
casted to integer 1 which is not greater than 1.

Have really similar structure:
| constraint_catalog - Name of the database containing the constraint (always the current database)
| constraint_schema - Name of the schema containing the constraint
| constraint_name - Name of the constraint
| check_clause - The check expression of the check constraint
Looks like current format of _ck_constraint comprises all of these fields.

Ok, then we are going to extend space format to make it

I agree with your position, so that I implemented this change in

I've solved this problem using smart column mask for AST-required
fields. It is a separate patch now. It's good enough, I think.

Talking "I have no idea how to implement something" is always
a bad decision. As I said earlier, you are not a text editor,
who just writes code fetched from review comments. What did you
do to investigate possibility of reusing OP_Column?
OP_Column has nothing to do with bind, but it contains all
the necessary tuple decoding, with caching of decoded fields,
and which you implemented again in ck_constraint.c with all these
column masks etc. IMO this is the reason, why SQL part of checks
still is huge. I expected, that this patchset should have almost
completely eliminated all check-hooks from SQL.
OP_Column in a nutshell takes raw tuple data, decodes to the
requested field number, remembers offsets to the decoded ones,
and returns the field. Next accesses of the same field are O(1).
Unused fields beyond max used field number are not even decoded.
This is the exact functionality we want in checks, and which you
are trying to do with the column mask.
The only problem is that OP_Column strongly depends on cursor.
You can either somehow refactor it, or split into 2 opcodes -
first fetches a tuple from a cursor, second fetches a field.
So as not to slow down OP_Column, we can make something similar
to OP_Function0 and OP_Function - OP_Function0 automatically
falls through to OP_Function. Here we can do something like:
case OP_Column:
/* take tuple data ... */
/* prepare to OP_Fetch call, fill needed registers ... */
FALLTHROUGH;
case OP_Fetch:
/* extract a column from tuple data */
break;
Column fetch has a context: array of offsets, flag if header is
parsed, raw tuple data etc. Since OP_Fetch should be able to work
without OP_Column, we need to extract that context into a struct
tuple_fetcher or something. Check compiler will call OP_Fetch for
referenced columns.
Now we need somehow to bind a tuple to the fetcher at runtime. For
that we could either
- create a fetcher on region with an existing tuple pointer and bind
it as some kind of cdata. For that you need to add a new sql_bind_*
function, which binds a raw pointer;
- or add an opcode OP_FetcherNew at compilation time, which will
create a fetcher, and take tuple data from a register, to which
we will bind tuple cdata at runtime. For that you again need to be
able to bind a pointer so as not to copy tuple data.
I think, the first way is better.
This solution solves another problem of your solution -
sql_bind_column copies data. If a CHECK constraint checks strings
or blobs, then it is expensive to copy them.
One another problem is that your solution is not scalable. You
implemented lots of machinery usable for checks only, but we will
have another place, where we need to access tuple fields without
a cursor - functional indexes. I am 99% sure, they will need the
same kind of 'fetcher' to extract fields from an existing tuple
data. It is impossible to implement all these column masks again
for each place, where we need to fetch tuple fields not from a
cursor.

======================================================
@TarantoolBot document
Title: check constraint for Lua space
The check constraint is a type of integrity constraint which
specifies a requirement that must be met by tuple before it
is inserted into space. The constraint result must be predictable.
Expression in check constraint must be <boolean value expression>
I.e. return boolean result.
Now it is possible to create ck constraints only for empty space
having format. Constraint expression is a string that defines
relations between top-level tuple fields.
Take into account that all names are converted to an uppercase
before resolve(like SQL does), use \" sign for names of fields
that were created not with SQL.
The check constraints are fired on insertion to the Lua space
together with Lua space triggers. The execution order of
ck constraints checks and space triggers follows their creation
sequence.
To create a new CK constraint for a space, use
s = box.schema.create_space('person')
_ = s:create_index('pk', {parts = {1, 'string'}})
s:format({{name='name', type='string'}, {name='age', type='integer'},
{name='experience', type='integer'}})
s:ck_constraint({'physics', '\"age\" > 14 and \"experience\" <
\"age\"'})
s:insert({"James Bond", 36, 36})
---
- error: 'Check constraint failed ''physics'': "age" > 14 and
"experience" < "age"'
...
s:insert("James Bond", 36, 16) -- success
s:insert({"Bobby", 6, 0})
---
- error: 'Check constraint failed ''physics'': "age" > 14 and
"experience" < "age"'
...
To list all ck constraints associated with space,
s:ck_constraint()
To replace ck constraint, use following syntax:

Expression in check constraint must be <boolean value expression>
I.e. return boolean result.

Describe please new order of execution: SQL triggers,
NoSQL triggers, check constraints and fk contraints.
And order between checks themselves.
Original check implementation executed check constraints
before NoSQL triggers.

Why not s:create_ck_constraint() OR s:create_check().
Let's discuss names and methods in our server chat.
So, now I won’t review code in patch since it may significantly change.
