safe_process puts its children (mysqld, in this case) into a separate
process group, to be able to kill it all at once.
buildslave kills mtr's process group when it loses connection to
the master.
result? buildslave kills mtr and safe_process, but leaves stale
mysqld processes in their own process groups.
fix: put safe_process itself into a separate process group, then
buildslave won't kill it and safe_process will kill mysqld'd
and itself when it will notice that the parent mtr no longer exists.
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.
mtr can crash occasionally.
This happens when mtr sends to a child mtr process (or vice-versa) a packet,
that gets truncated or, perhaps, split in two.
Then the other side cannot deserialize it and fails as above.
This makes it clear that the error code has nothing to do with errno.
mysql-test/include/mtr_warnings.sql:
Fixed suppression for new slave error messages
mysql-test/lib/My/Test.pm:
Use 'send' instead of 'print' to avoid errors about "wrong class ... back attempt"
mysql-test/lib/v1/mtr_report.pl:
Fixed suppression for new slave error messages
mysql-test/mysql-test-run.pl:
Fixed suppression for new slave error messages
Removed warning from perl 5.16.2 about arrays
mysql-test/r/flush_read_lock.result:
Fixed suppression for new slave error messages
sql/rpl_reporting.cc:
Instead of writing "Errcode" to the log for Slave errors, use "Internal MariaDB error code"
mysys/errors.c:
revert upstream's fix. use a much simpler one
mysys/my_write.c:
revert upstream's fix. use a simpler one
sql/item_xmlfunc.cc:
useless, but ok
sql/mysqld.cc:
simplify upstream's fix
storage/heap/hp_delete.c:
remove upstream's fix.
we'll use a much less expensive approach.
and small collateral changes
mysql-test/lib/My/Test.pm:
somehow with "print" we get truncated writes sometimes
mysql-test/suite/perfschema/r/digest_table_full.result:
md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/perfschema/r/dml_handler.result:
host table is not ported over yet
mysql-test/suite/perfschema/r/information_schema.result:
host table is not ported over yet
mysql-test/suite/perfschema/r/nesting.result:
this differs, because we don't rewrite general log queries, and multi-statement
packets are logged as a one entry. this result file is identical to what mysql-5.6.5
produces with the --log-raw option.
mysql-test/suite/perfschema/r/relaylog.result:
MariaDB modifies the binlog index file directly, while MySQL 5.6 has a feature "crash-safe binlog index" and modifies a special "crash-safe" shadow copy of the index file and then moves it over. That's why this test shows "NONE" index file writes in MySQL and "MANY" in MariaDB.
mysql-test/suite/perfschema/r/server_init.result:
MariaDB initializes the "manager" resources from the "manager" thread, and starts this thread only when --flush-time is not 0. MySQL 5.6 initializes "manager" resources unconditionally on server startup.
mysql-test/suite/perfschema/r/stage_mdl_global.result:
this differs, because MariaDB disables query cache when query_cache_size=0. MySQL does not
do that, and this causes useless mutex locks and waits.
mysql-test/suite/perfschema/r/statement_digest.result:
md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/perfschema/r/statement_digest_consumers.result:
md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/perfschema/r/statement_digest_long_query.result:
md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/rpl/r/rpl_mixed_drop_create_temp_table.result:
will be updated to match 5.6 when alfranio.correia@oracle.com-20110512172919-c1b5kmum4h52g0ni and anders.song@greatopensource.com-20110105052107-zoab0bsf5a6xxk2y are merged
mysql-test/suite/rpl/r/rpl_non_direct_mixed_mixing_engines.result:
will be updated to match 5.6 when anders.song@greatopensource.com-20110105052107-zoab0bsf5a6xxk2y is merged
mysql-test/README.suites:
removed. it was turned into a manual, eventually
mysql-test/include/default_mysqld.cnf:
use normal environment variables instead of magic @OPT.vardir
mysql-test/lib/My/ConfigFactory.pm:
use normal environment variables instead of magic @OPT.vardir
mysql-test/mysql-test-run.pl:
initialize environment variables before parsing the first my.cnf template - it may refer to them
mysql-test/suite/sphinx/my.cnf:
use normal environment variables instead of magic @OPT.vardir
mysql-test-run auto-disables all optional plugins.
mysql-test/include/default_client.cnf:
no @OPT.plugindir anymore
mysql-test/include/default_mysqld.cnf:
don't disable plugins manually - mtr can do it better
mysql-test/suite/innodb/t/innodb_bug47167.test:
mtr now uses suite-dir as an include path
mysql-test/suite/innodb/t/innodb_file_format.test:
mtr now uses suite-dir as an include path
mysql-test/t/partition_binlog.test:
this test uses partitions
storage/example/mysql-test/mtr/t/source.result:
update results. as mysqltest includes the correct overlayed include
storage/innobase/handler/ha_innodb.cc:
the assert is wrong
storage/innobase/handler/handler0alter.cc:
for NEWDATE key_type says unsigned, thus col->prtype says unsigned,
but field->flags says signed. Use the same flag for value retrieval
that was used for value storage.
