Bug Fixes

  • Fixed InnoDB I/O code so that the interrupted system calls are restarted if they are interrupted by a signal. InnoDB I/O code was not fully conforming to the standard on POSIX systems, causing a crash with an assertion failure when receiving a signal on pwrite(). Bug Fixed: LaunchPad: #764395 / MySQL bug #60788 (A. Kopytov)
  • The maximum value for innodb_use_purge_threads has been corrected to 32 (maximum number of parallel threads in a parallelized operation). The innodb_purge_thread patch accepted a value up to 64 for the innodb_use_purge_thread variable, leading to an assertion failure for greater than the actual maximum. Bug Fixed: #755017 (L. Biveinis)
