Bugs Fixed

Due to incorrect usage of posix_fadvise() hints, Percona XtraBackup discarded read-ahead buffers which resulted in higher I/O rate on the backup stage. Bug fixed #1093385.

Spurious trailing data blocks that would normally be ignored by InnoDB could lead to an assertion failure on the backup stage. Bug fixed #1177201.

A spurious warning message could cause issues with third-party wrapper scripts. Bug fixed #1271956.

xbcrypt could fail with the xbcrypt:xb_crypt_read_chunk: unable to read chunk iv size at offset error under some circumstances. Bug fixed #1273196.

xbstream could sometimes hang when extracting a broken or incomplete input stream. Bug fixed #1273207.

Preparing backups of MySQL or Percona Server 5.6 could raise an assertion failure in Percona XtraBackup. Bug fixed #1273468.

The downtime is decreased when the innobackupex --safe-slave-backup option is used to backup a replication slave. The SQL thread is now started before a temporary copy of redo log is streamed into the final location. Bug fixed #1284778.

Disabled the “binary version check” functionality in the VersionCheck module due to security concerns. Bug fixed #1285166.

Other bugs fixed: #1284078.
