Bug 1340717: Crash on prepare partial backup with 5.6-based
xtrabackup
The root cause of the crash is that purge_sys is not initialized
at the moment when xtrabackup trying to delete missing tablespace.
Fix for upstream Bug#16593427 "ROLLBACK OF RECOVERED TRANSACTION
CORRUPTS NON-ONLINE ADD INDEX" introduced function
trx_resurrect_table_locks which being executed before purge_sys
initialized. It loads some tablepsaces in data dictionary. Crash
happens when tablespace is missing from partial backup.
Fix is not to remove missing tablespaces from data dictionary
until purge_sys is initialized. They will be eventually removed
during subsequent operation.
Test case for this bug starts transaction and takes a backup while
transaction is still running. Upon apply-log there will be crash if
bug is present.
