Bugs Fixed¶
-
When using skip-innodb_doublewrite in my.cnf, a parallel doublewrite buffer is still created. Bugs fixed #3411.
-
During a binlogging replication event, if the master crashes after the multi-threaded slave has begun copying to the slave’s relay log and before the process has completed, a STOP SLAVE on the slave takes longer than expected. Bug fixed #5824.
-
If pam_krb5 is configured to allow the user to change their password, and the password expired, the server crashed after receiving the new password. Bug fixed #6023.
Other bugs fixed: #5859, #5910, #5966, #4784, #5216, #5327, #5584, #5642, #5659, #5754, #5761, #5797, #5875, #5933, #5941, #5997, #6050, #6052, #3345, and #5585
