  • PS-5391: RedHat-based distributions may set service configurations in a file saved in the ‘/etc/sysconfig’ directory. The init script did not read any file in that directory. We have added the ability for the init.d script to read files in the ‘etc/sysconfig’ directory.

Bugs Fixed

  • PS-6953: If the LOAD DATA process found a line with an escape character followed by UTF8 characters, then the process failed to load the line and any additional lines. This issue was a regression. (Upstream #98089)
  • PS-6945: The tokubackup process exported an incorrect API. This API mismatch prevented large file backups.
  • PS-6946: The address and thread sanitizers found memory use after free and other issues in the tokubackup software..
  • PS-7020: In Ubuntu 20.04, only python3-mysqldb is available. We converted the MTR tests to support both Python2 and Python3. The scripts require Python2.6 or newer.
  • PS-6954: In the tokudb-backup-plugin, there was a collision between -std=c++11 and -std=gnu++03.
  • PS-6899: The tests, main.events_bugs and main.events_1, failed because 2020-01-01 was considered a future time. (Upstream #98860)
  • PS-6110: The was missing from Percona-Server-5.6.46-rel86.2-Linux.x86_64.ssl101.tar.gz.
  • PS-4649: TokuDB: Documented PerconaFT, which is fractal tree indexing. This type of indexing enhances the B-tree data structure.
  • PS-6966: In Percona Server compilation, fixed clang-10 compilation issues. (Upstream #99221)
