New Features
- Percona XtraBackup has now been rebased on MySQL 5.6.17.
- Percona XtraBackup package is now available for Ubuntu 14.04.
Bugs Fixed
- Percona XtraBackup couldn’t be built with Bison 3.0. Bug fixed #1262439.
- The xtrabackup binaries now recognize a new
my.cnf
option,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 andulimit
settings. Bug fixed #1183793. - If a remote InnoDB tablespace got
CREATE
d orALTER
ed during the backup, an attempt to prepare such a backup later would lead to Percona XtraBackup crash. Bug fixed #1291299. - Code in both
innobackupex
andxtrabackup
, that was supposed to make sure no child processes are left running in caseinnobackupex
got killed or failed with an error, relied on the fact theSIGTERM
andSIGINT
signals were not blocked by thextrabackup
process. However, bothSIGTERM
andSIGINT
might be blocked by the process that had invokedinnobackupex
, 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 replacingSIGTERM
in innobackupex andSIGINT
in xtrabackup auto-termination withSIGKILL
. 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.
