New Features
- Percona XtraBackuphas now been rebased onMySQL5.6.17.
- Percona XtraBackuppackage is now available forUbuntu14.04.
Bugs Fixed
- Percona XtraBackupcouldn’t be built withBison3.0. 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 remoteInnoDBtablespace got
CREATE
d orALTER
ed during the backup, an attempt to prepare such a backup later would lead toPercona XtraBackupcrash. 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 thePercona XtraDB Clusterserver 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 theInnoDBdata dictionary, introduced inMySQL5.6.16, wasn’t recognized byPercona XtraBackupwhich lead to “
InnoDB: in InnoDB data dictionary has unknown flags 50.
” warnings. Fixed by rebasingPercona XtraBackuponMySQL5.6.17. Bug fixed#1302882.
