This release is the current GA (Generally Available) stable release in the 2.1 series. Percona XtraBackup is an open source, free MySQL hot backup software that performs non-blocking backups for InnoDB and XtraDB databases. Percona XtraBackup is an open source, free MySQL hot backup software that performs non-blocking backups for InnoDB and XtraDB databases.
- Percona XtraBackup has now been rebased on MySQL 5.6.17.
- Percona XtraBackup package is now available for Ubuntu 14.04.
- Percona XtraBackup couldn’t be built with Bison 3.0. Bug fixed #1262439.
- The xtrabackup binaries now recognize a new
open_files_limit. The effect is the same as for the server: it changes the maximum number of file descriptors available to the xtrabackup process. The actual limit depends on the platform and
ulimitsettings. Bug fixed #1183793.
- If a remote InnoDB tablespace got
ALTERed during the backup, an attempt to prepare such a backup later would lead to Percona XtraBackup crash. Bug fixed #1291299.
- Code in both
xtrabackup, that was supposed to make sure no child processes are left running in case
innobackupexgot killed or failed with an error, relied on the fact the
SIGINTsignals were not blocked by the
xtrabackupprocess. However, both
SIGINTmight be blocked by the process that had invoked
innobackupex, for example, by the Percona XtraDB Cluster server processes doing an SST, in which case they were also blocked by the xtrabackup process, since the signal mask is inherited by child processes. Fixed by replacing
SIGTERMin innobackupex and
SIGINTin xtrabackup auto-termination with
SIGKILL. Bug fixed #1294782.
- A new table flag in the InnoDB data dictionary, introduced in MySQL 5.6.16, wasn’t recognized by Percona XtraBackup which lead to “
InnoDB: in InnoDB data dictionary has unknown flags 50.” warnings. Fixed by rebasing Percona XtraBackup on MySQL 5.6.17. Bug fixed #1302882.
