Fixed a couple of race conditions in the test case to ensure stable order
of events. Also removed all sleeps. Test execution time is down from 18s
to 0.15s.
On disconnect audit event is triggered after control is returned to
mysqltest client. Which means mysqltest may issue more commands
concurrently before disconnect is actually logged.
Similar problem happens with regular query execution: an event is
triggered after control is returner to the client. Which may end
up with unstable order of events in different connections.
Delayed insert rows are enqueued separately and can either be combined
into single event or go as separate events. Reduced number of inserted
rows to 1 to stabilize result.
Also backported 2b3f6ab from 10.5.
If the SET PASSWORD query doesn't have the password string,
the parsing of it can fail. It manifested first in MySQL 5.6 as
it started to hide password lines sent to the plugins.
Fixed by checking for that case.
The reason was that a couple of variables that hold number of rows that was used to calculate buffers was uint and caused an overflow.
Fixed by changing variables that could hold number of rows from uint to ulong and also added a cast for this test.
include/heap.h:
Reorder to get better alignment. Changed variables that could hold number of rows from uint to ulong
mysql-test/suite/heap/heap.result:
Added test case
mysql-test/suite/heap/heap.test:
Added test case
mysql-test/suite/plugins/t/server_audit.test:
Added sleep as we want to have disconnect logged before we try a new connect
storage/heap/ha_heap.cc:
Changed variables that could hold number of rows from uint to ulong
Limit number of rows to 4G (as most of the variables that holds rows are ulong anyway)
reset records_changed when key_stat_version is changed to not cause increments for every row changed
storage/heap/ha_heap.h:
changed records_changed to ulong as this can get big
storage/heap/hp_create.c:
Changed variables that could hold number of rows from uint to ulong
Added cast (fixed the original bug)
storage/heap/hp_delete.c:
Changed variables that could hold number of rows from uint to ulong
storage/heap/hp_open.c:
Removed not needed cast
storage/heap/hp_write.c:
Changed variables that could hold number of rows from uint to ulong
support-files/compiler_warnings.supp:
Removed extra : from supression
