lock_place_prdt_page_lock(): Do not place locks on temporary tables.
Temporary tables can only be accessed from one connection, so
it does not make any sense to acquire any transactional locks on them.
This is based on commit 20ae4816bb
with some adjustments for MDEV-12353.
row_ins_sec_index_entry_low(): If a separate mini-transaction is
needed to adjust the minimum bounding rectangle (MBR) in the parent
page, we must disable redo logging if the table is a temporary table.
For temporary tables, no log is supposed to be written, because
the temporary tablespace will be reinitialized on server restart.
rtr_update_mbr_field(), rtr_merge_and_update_mbr(): Changed the return
type to void and removed unreachable code. In older versions, these
used to return a different value for temporary tables.
page_id_t: Add constexpr to most member functions.
mtr_t::log_write(): Catch log writes to invalid tablespaces
so that the test case would crash without the fix to
row_ins_sec_index_entry_low().
row_ins_sec_index_entry_low(): If a separate mini-transaction is
needed to adjust the minimum bounding rectangle (MBR) in the parent
page, we must disable redo logging if the table is a temporary table.
For temporary tables, no log is supposed to be written, because
the temporary tablespace will be reinitialized on server restart.
rtr_update_mbr_field(): Plug a memory leak.
This essentially reverts commit 4e89ec6692
and only disables InnoDB persistent statistics for tests where it is
desirable. By design, InnoDB persistent statistics will not be updated
except by ANALYZE TABLE or by STATS_AUTO_RECALC.
The internal transactions that update persistent InnoDB statistics
in background tasks (with innodb_stats_auto_recalc=ON) may cause
nondeterministic query plans or interfere with some tests that deal
with other InnoDB internals, such as the purge of transaction history.
Import operation without .cfg file fails when there is mismatch of index
between metadata table and .ibd file. Moreover, MDEV-19022 shows
that InnoDB can end up with index tree where non-leaf page has only
one child page. So it is unsafe to find the secondary index root page.
This patch does the following when importing the table without .cfg file:
1) If the metadata contains more than one index then InnoDB stops
the import operation and report the user to drop all secondary
indexes before doing import operation.
2) When the metadata contain only clustered index then InnoDB finds the
index id by reading page 0 & page 3 instead of traversing the
whole tablespace.
InnoDB should calculate the MBR for the first field of
spatial index and do the comparison with the clustered
index field MBR. Due to MDEV-25459 refactoring, InnoDB
calculate the length of the first field and fails with
too long column error.
