Merged lp:maria/maria-10.0-galera up to revision 3879.
Added a new functions to handler API to forcefully abort_transaction,
producing fake_trx_id, get_checkpoint and set_checkpoint for XA. These
were added for future possiblity to add more storage engines that
could use galera replication.
Allow "rpm -q --whatprovides mysql-server" to return more than one row.
(all rows should be identical though)
support-files/rpm/server-prein.sh:
don't use "head -1" or "uniq" to avoid introducing new dependencies.
"sed" is already used in this script.
before running mysql_install_db check for the existence
of $datadir/mysql, not simply $datadir ($datadir might be mounted on
a separate device - exists, but empty)
cmake/cpack_rpm.cmake:
* mark all cnf files with %config(noreplace)
* add the forgotten postun script
sql/sys_vars.cc:
0 for a string variable means "no default. But datadir has the default value.
support-files/rpm/server-postin.sh:
* use mysqld --help to determine the correct datadir in the presence of my.cnf files
(better than my_print_defaults, because it considers the correct group set).
* Only create users, and chown/chmod if it's a fresh install, not an upgrade.
* only run mysql_install_db if datadir does not exist
