Nikita Malyavin 25e2d0a6bb MDEV-34632 Assertion failed in handler::assert_icp_limitations ... Assertion `table->field[0]->ptr >= table->record[0] && table->field[0]->ptr <= table->record[0] + table->s->reclength' failed in handler::assert_icp_limitations. table->move_fields has some limitations: 1. It cannot be used in cascade 2. It should always have a restoring pair. Rule 1 is covered by assertions in handler::assert_icp_limitations and handler::ptr_in_record (commit 30894fe9a9). Rule 2 should be manually maintained with care. Hopefully, the rule 1 assertions may sometimes help as well. In ha_myisam::repair, both rules are broken. table->move_fields is used asymmetrically there: it is set on every param->fix_record call (i.e. in compute_vcols) but is restored only once, in the end of repair. The reason to updating field ptr's for every call is that compute_vcols can (supposedly) be called in parallel, that is, with the same table, but different records. The condition to "unmove" the pointers in ha_myisam::restore_vcos_after_repair is incorrect, when stored vcols are available, and myisam stores a VIRTUAL field if it's the only field in the table (the record cannot be of zero length). This patch solves the problem by "unmoving" the pointers symmetrically, in compute_vcols. That is, both rules will be preserved maintained.		2024-08-07 14:50:19 +02:00
