Hi Paul,
I'm merging MySQL 5.1.46 into MariaDB. But I hit a test failure in PBXT, see
below.
It is wrong result from a SELECT. Interestingly, the same SELECT in the main
test suite seems to work correctly.
The code is in
lp:~maria-captains/maria/5.1-release
Can you maybe take a look, in case it is a PBXT issue? Probably also one of
our optimiser people should take a look to see if it is a server problem. It's
a bit strange that it seems to be pbxt specific, I'm wondering if there was a
subtle change of the storage engine API introduced or something?
Test failure link and output below.
- Kristian.
