MDEV-27233 Server hangs when using --init-file which loads Spider and creates a Spider table
Spider waits until the server initialization is complete
(i.e., mysqld_server_started == 1) before creating the Spider system
tables like mysql.spider_XX. Spider also wait until the tables are
created before instantiating ha_spider.
This results in dead lock when Spider is loaded and a non-system
Spider table is created by --in-file because queries passed by
--in-file are executed during the server initialization
(i.e., mysqld_server_started == 0).
In the first place, there seems to be no need for Spider to wait until
the server initialization is completed before creating the system
tables. Thus, we simply remove that synchronization.
fil_name_process(): If the recovery of a tablespace was deferred,
do invoke fil_ibd_load() even though the name in recv_spaces is
not changing. This allows us to recover from a situation where
there are many FILE_RENAME records, renaming a tablespace back
and forth, and a FILE_MODIFY record that had been written by
fil_names_clear().
MDEV-28920 Rescheduling of innodb_stats_func() missing
Fixed tpool timer implementation on POSIX.
Prior to this patch, under some specific rare circumstances (concurrency
related), timer callback execution might be skipped.
When attempting to recover a database with an incorrect encryption key,
the unencrypted page contents should be expected to differ from what
was written before recovery. Let us suppress some more messages.
This caused intermittent failures, depending on when the latest
log checkpoint was triggered.
