Problem 1: main.loaddata tried to trigger an error caused by
reading files outside the vardir, by reading itself. However,
if loaddata.test is not world-readable (e.g., umask=0077),
then another error is triggered.
Fix 1: allow the other error too.
Problem 2: rpl_slave_skip and rpl_innodb_mixed_dml tried to
copy a file from mysql-test/suite/rpl/data to mysql-test/var
and then read it. That failed too if umask=0077, since the
file would not become world-readable.
Fix 2: move the files from mysql-test/suite/rpl/data to
mysql-test/std_data and update tests accordingly. Remove
the directory mysql-test/suite/rpl/data.
mysql-test/r/loaddata.result:
Updated result file.
mysql-test/std_data/rpl_bug28618.dat:
Moved this file to std_data.
mysql-test/std_data/rpl_mixed.dat:
Moved this file to std_data.
mysql-test/suite/rpl/data:
Removed directory that is now unused.
mysql-test/suite/rpl/include/rpl_mixed_dml.inc:
The rpl_mixed.dat file has been moved. Updated the test to
use the new location.
mysql-test/suite/rpl/r/rpl_innodb_mixed_dml.result:
Updated result file.
mysql-test/suite/rpl/r/rpl_slave_skip.result:
Updated result file.
mysql-test/suite/rpl/t/rpl_slave_skip.test:
The rpl_bug28618.dat file has been moved. Updated the test
to use the new location.
mysql-test/t/loaddata.test:
Allow more error messages. ER_TEXTFILE_NOT_READABLE may
happen if the file is not world-readable (which may happen,
e.g., if the user has umask=0077).
is possible):
When skipping the beginning of a transaction starting with BEGIN, the OPTION_BEGIN
flag was not set correctly, which caused the slave to not recognize that it was
inside a group. This patch sets the OPTION_BEGIN flag for BEGIN, COMMIT, ROLLBACK,
and XID events. It also adds checks if inside a group before decreasing the
slave skip counter to zero.
Begin_query_log_event was not marked that it could not end a group, which is now
corrected.
mysql-test/extra/rpl_tests/rpl_extraSlave_Col.test:
Correcting slave skip counter to get the correct behaviour.
mysql-test/suite/rpl/r/rpl_slave_skip.result:
Result change.
mysql-test/suite/rpl/t/rpl_slave_skip.test:
Adding tests to check that skipping works for transactions:
- Skipping one group with BEGIN first
- Skipping two groups with BEGIN first
- Skipping one group without BEGIN first but with AUTOCOMMIT=0
- LOAD DATA INFILE under statement-based replication
mysql-test/suite/rpl_ndb/r/rpl_ndb_extraCol.result:
Result change.
sql/log_event.cc:
Adding checks if we're in a group when the slave skip counter is 1.
In that case, we should keep going.
Adding helping member function Log_event::continue_group() denoting
that this event cannot end a group, and if the skip counter indicates
that the group ends after this event, it should not decrease the skip
counter.
Query_log_event will change the OPTION_BEGIN flag for BEGIN, COMMIT, and
ROLLBACK, even when skipping because of a positive skip count, and
Xid_log_event will also affect the OPTION_BEGIN flag, even when being
skipped.
Begin_load_query_log_event cannot end a group, so it is marked to
continue the group.
sql/log_event.h:
Adding helper function Log_event::continue_group().
sql/rpl_rli.h:
Adding Relay_log_info::get_flag() to get the value of a
replication flag.
sql/slave.cc:
Adding debug output and changing debug message.
mysql-test/suite/rpl/data/rpl_bug28618.dat:
New BitKeeper file ``mysql-test/suite/rpl/data/rpl_bug28618.dat''
mysql-test/suite/rpl/t/rpl_slave_skip-slave.opt:
New BitKeeper file ``mysql-test/suite/rpl/t/rpl_slave_skip-slave.opt''
