MDEV-11562 Assertion `js->state == JST_VALUE' failed in check_contains(json_engine_t*, json_engine_t*). check_contains() fixed. When an item of an array is a complex structure, it can be half-read after the end of the recursive check_contains() call. So we just manually get to it's ending.

in slow shutdown mode stop all bg threads that might generate new undo records to purge before stopping purge threads.

Sergei Golubchik authored
in slow shutdown mode purge threads really must exit only when there is nothing to purge. Restore the trx_commit_disallowed check and don't stop purge threads until all connection thread transactions are gone.

The patch for bug mdev-10882 tried to fix it by providing an implementation of the virtual method build_clone for the class Item_cache. It's turned out that it is not easy provide a valid implementation for Item_cache::build_clone(). At the same time if the condition that can be pushed into a materialized view contains a cached item this item can be substituted for a basic constant of the same value. In such a way we can avoid building proper clones for Item_cache objects when constructing pushdown conditions.

Aria supports virtual columns, but does not support indexes on virtual columns. Let's issue an appropriate error in this case.

now, when expr_str is gone, expr_item can be unambiguously renamed to expr.

otherwise we'd need to store sql_mode *per vcol* (consider CREATE INDEX...) and how SHOW CREATE TABLE would support that? Additionally, get rid of vcol::expr_str, just to make sure the string is always generated and never leaked in the original form.

* remove old 5.2+ InnoDB support for virtual columns * enable corresponding parts of the innodb-5.7 sources * copy corresponding test cases from 5.7 * copy detailed Alter_inplace_info::HA_ALTER_FLAGS flags from 5.7 - and more detailed detection of changes in fill_alter_inplace_info() * more "innodb compatibility hooks" in sql_class.cc to - create/destroy/reset a THD (used by background purge threads) - find a prelocked table by name - open a table (from a background purge thread) * different from 5.7: - new service thread "thd_destructor_proxy" to make sure all THDs are destroyed at the correct point in time during the server shutdown - proper opening/closing of tables for vcol evaluations in + FK checks (use already opened prelocked tables) + purge threads (open the table, MDLock it, add it to tdc, close when not needed) - cache open tables in vc_templ - avoid unnecessary allocations, reuse table->record[0] and table->s->default_values - not needed in 5.7, because it overcalculates: + tell the server to calculate vcols for an on-going inline ADD INDEX + calculate vcols for correct error messages * update other engines (mroonga/tokudb) accordingly
