- added join cache indication in EXPLAIN (Extra column).
- prefer filesort over full scan over
index for ORDER BY (because it's faster).
- when switching from REF to RANGE because
RANGE uses longer key turn off sort on
the head table only as the resulting
RANGE access is a candidate for join cache
and we don't want to disable it by sorting
on the first table only.
- Make the range-et-al optimizer produce E(#table records after table
condition is applied),
- Make the join optimizer use this value,
- Add "filtered" column to EXPLAIN EXTENDED to show
fraction of records left after table condition is applied
- Adjust test results, add comments
- Added show status variable "compression" for checking that compression is turned on.
- Updated show status variable "have_openssl" to be set to DISABLED if server supports ssl but it's not turned on to accept incoming ssl connections.
- Setup server to accept ssl connections from clients ig that is supported by server
- New tests
- ssl - Run with ssl turned on
- ssl_compress - Run with ssl and compression turned on
- compress - Run with compression turned in
- Updated test
- openssl_1, rpl_openssl1 - Changed to run if server supports ssl
