[tarantool-patches] [PATCH v2 0/3] sql: clean-up in case constraint creation failed

[imeevma@tarantool.org]

This patch makes VDBE run destructors before halting in case
constraint creation failed. This is done using new opcode
OP_Error, which allows to set an error and do a jump without
halting VDBE.

https://github.com/tarantool/tarantool/issues/4183
https://github.com/tarantool/tarantool/tree/imeevma/gh-4183-clean-up-when-constraint-creation-failed

Changes in v2:
1) Opcode OP_Error was renamed to OP_SetDiag
2) Now OP_SetDiag is used for diag_set() for all VDBE errors. This
functionality has been removed from OP_Halt.
3) Fixed error with broken destructors for constraints.

Mergen Imeev (3):
  sql: add OP_SetDiag opcode in VDBE
  sql: clean-up in case constraint creation failed
  sql: Fix destructors for constraints
