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.
ALTERed during the backup, an attempt to prepare such a backup later would lead to Percona XtraBackup crash. Bug fixed #1291299.
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.
