This patch-set is a follow-up for issue #4074. Since we are using
the Tarantool error system, the SQL error system should be
removed.
https://github.com/tarantool/tarantool/issues/4074
https://github.com/tarantool/tarantool/tree/imeevma/gh-4074-diag_set-in-vdbe
Mergen Imeev (21):
sql: remove unused functions of SQL error system
sql: disable lookaside system
sql: remove SQL_OK error/status code
sql: remove SQL_PERM, SQL_WARNING, SQL_ABORT errcodes
sql: remove SQL_CANTOPEN errcode
sql: remove SQL_NOTFOUND error/status code
sql: remove SQL_LOCKED errcode
sql: remove SQL_FULL errcode
sql: remove SQL_MISUSE errcode
sql: remove SQL_RANGE errcode
sql: remove SQL_SCHEMA errcode
sql: remove SQL_TOOBIG errcode
sql: remove SQL_BUSY errcode
sql: remove SQL_CONSTRAINT errcode
sql: remove SQL_ERROR errcode
sql: remove SQL_NOMEM errcode
sql: remove SQL_IOERR errcode
sql: remove SQL_TARANTOOL_ERROR errcode
sql: remove field errMask from struct sql
sql: replace rc by is_aborted in struct Parse
sql: remove sql_log()

I’ve found two mentions of this macro in sqlInt.h:
in comment for sqlColumnsFromExprList() and
in comment for sql_analysis_load(). Remove
them as well.

Taking into consideration assert above, it could
be replaced with assert(pBuilder->nRecValid == nEq - 1);
Btw, this function doesn’t seem to be called at all:
unreachable() assert doesn’t fire. I can assume that it is
connected with stat tables.

I guess this refactoring is incorrect a bit. Here you always set
ER_SQL_BIND_VALUE. However, sqlVdbeMemSetStr() and
sql_bind_zeroblob64() already set ER_SQL_EXECUTE error
in case “string or blob is too big”. Probably, this case is not
covered by tests. Please, come up with test case on this condition.

This routine may turn out to be useful when we add
working prepared statements.

NIkita, could you please be more specific, is it an accept or a
reject? Can review comments be done in their own patches?
This is a big patch stack and I would like us to stop shuffling it
around. If it does improve things, let it get in please and do the
follow up work separately. Or at least let some of the good
patches in.

I think that we do not have the right way to check this, so
I think that we will either enable or delete this function
when the statistics table is created.

Fixed:
sql: replace rc by is_aborted in struct VDBE
Currently, the rc field of the VDBE structure is either 0 or -1.
Due to this, it is better to replace this integer field with the
boolean field is_aborted.

Fixed.
Also, I returned the sqlVdbeResetStepResult() function,
since it is now used in seqReprepare().

Hi! Thank you for review! My answer below. Also you can
there diff for patch "sql: remove SQL_RANGE errcode",
new patch "sql: remove SQL_RANGE errcode" and new patch
"sql: remove SQL_TOOBIG".

After some research, I found that this refactoring was definitely
wrong. One reason for this is that you should not set an error
here. If one of the functions sql_bind_ *() returns not 0, it
means that the error has already been set.
After another investigation, I found that one of the assertions I
made in the "sql: remove SQL_RANGE errcode" patch shows an error.
This error is caught by pcall() in tests, so I failed to find it
earlier.
I did some refactoring in the "sql: remove SQL_RANGE errcode"
patch, which solved mentioned problem.

I’d say it is rather accept. This fix touches QP and now I
can’t validate it since statistics functionality is disabled.

Is it common practice for our work-flow? I mean I see
that as a rule fixe are done and squashed with main
patches before they are pushed.

I don’t mind if those patches which I didn’t comment out
will be pushed separately. There’re not so many concerns
from my side, so I guess whole patch-set will be ready soon.
