when generating new name.
If find_uniq_filename returns an error, then this error is not
being propagated upwards, and execution does not report error to
the user (although a entry in the error log is generated).
Additionally, some more errors were ignored in new_file_impl:
- when writing the rotate event
- when reopening the index and binary log file
This patch addresses this by propagating the error up in the
execution stack. Furthermore, when rotation of the binary log
fails, an incident event is written, because there may be a
chance that some changes for a given statement, were not properly
logged. For example, in SBR, LOAD DATA INFILE statement requires
more than one event to be logged, should rotation fail while
logging part of the LOAD DATA events, then the logged data would
become inconsistent with the data in the storage engine.
mysql-test/include/restart_mysqld.inc:
Refactored restart_mysqld so that it is not hardcoded for
mysqld.1, but rather for the current server.
mysql-test/suite/binlog/t/binlog_index.test:
The error on open of index and binary log on new_file_impl
is now caught. Thence the user will get an error message.
We need to accomodate this change in the test case for the
failing FLUSH LOGS.
mysql-test/suite/rpl/t/rpl_binlog_errors-master.opt:
Sets max_binlog_size to 4096.
mysql-test/suite/rpl/t/rpl_binlog_errors.test:
Added some test cases for asserting that the error is found
and reported.
sql/handler.cc:
Catching error now returned by unlog (in ha_commit_trans) and

sql/log.cc:
Propagating errors from new_file_impl upwards. The errors that
new_file_impl catches now are:
- error on generate_new_name
- error on writing the rotate event
- error when opening the index or the binary log file.
sql/log.h:
Changing declaration of:
- rotate_and_purge
- new_file
- new_file_without_locking
- new_file_impl

Changes to catch the return from rotate_and_purge.
sql/slave.cc:
Changes to catch the return values for new_file and rotate_relay_log.
sql/slave.h:
Changes to rotate_relay_log declaration (now returns int
instead of void).
sql/sql_load.cc:
In SBR, some logging of LOAD DATA events goes through
IO_CACHE_CALLBACK invocation at mf_iocache.c:_my_b_get. The
IO_CACHE implementation is ignoring the return value for from
these callbacks (pre_read and post_read), so we need to find out
at the end of the execution if the error is set or not in THD.
sql/sql_parse.cc:
Catching the rotate_relay_log and rotate_and_purge return values.
Semantic change in reload_acl_and_cache so that we report errors
in binlog interactions through the write_to_binlog output parameter.
If there was any failure while rotating the binary log, we should
then report the error to the client when handling SQLCOMM_FLUSH.
Improved error handling such that queries against Information_Schema.Tables won't
fail if a Federated table is unable to connect to remote host.
sql/sql_show.cc:
If Handler::Info() fails, save error text in TABLE COMMENTS column, clear error.
When using BINLOG statement to execute rows log events, session variables
foreign_key_checks and unique_checks are changed temporarily. As each rows
log event has their own special session environment and its own
foreign_key_checks and unique_checks can be different from current session
which executing the BINLOG statement. But these variables are not restored
correctly after BINLOG statement. This problem will cause that the following
statements fail or generate unexpected data.
In this patch, code is added to backup and restore these two variables.
So BINLOG statement will not affect current session's variables again.

win x86 debug_max
The windows MTR run exhibited a different test execution
ordering (due to the fact that in these platforms MTR is invoked
with --parallel > 1). This uncovered a bug in the aforementioned
test case, which is triggered by the following conditions:
1. server is not restarted between two different tests;
2. the test before binlog.binlog_row_failure_mixing_engines
issues flush logs;
3. binlog.binlog_row_failure_mixing_engines uses binlog
positions to limit the output of show_binlog_events;
4. binlog.binlog_row_failure_mixing_engines does not state which
binlog file to use, thence it uses a wrong binlog file with
the correct position.
There are two possible fixes: 1. make sure that the test start
from a clean slate - binlog wise; 2. in addition to the position,
also state the binary log file before sourcing
show_binlog_events.inc .
We go for fix#1, ie, deploy a RESET MASTER before the test is
actually started.

After dropping and recreating the database specified along with --one-database
option at command line, mysql client keeps filtering the statements even after
the execution of a 'USE' command on the same database.
--one-database option enables the filtering of statements when the current
database is not the one specified at the command line. However, when the same
database is dropped and recreated the variable (current_db) that holds the
inital database name gets altered. This bug exploits the fact that current_db
initially gets set to null value (0) when a 'use db_name' follows the recreation
of same database db_name (speficied at the command line) and hence skip_updates
gets set to 1, which inturn triggers the further filtering of statements.
Fixed by making get_current_db() a no-op function when one_database is set,
and hence, under that condition current_db will not get altered.
Note, however the value of current_db can change when we execute 'connect'
command with a differnet database to reconnect to the server, in which case,
the behavior of --one-database will be formulated using this new database.
client/mysql.cc:
Bug #54899 : --one-database option cannot handle DROP/CREATE DATABASE commands
Added an if statement at the beginnning of get_current_db() , which makes it
a no-op function if one-database option is specified, and hence current_db
remains unchanged.
Changed the help message for one-database option to a more appropriate message
as specified in mysql documentation.
mysql-test/r/mysql.result:
Added a test case for bug#54899 and some more test cases to
check other one-database option related behaviors.
mysql-test/t/mysql.test:
Added a test case for bug#54899 and some more test cases to

It does work in general, the problem here was that the test name

If mysqltest dies, mtr waits to see if mysqld dies too within 100ms
But in that case, it should not care about expected crash
Fix: jump past the code that checks the expect file
OPTIMIZE TABLE recreates the whole table. That is why the counter gets reset.
Making the next autoinc column persistent is a separate issue from resetting
the value after an OPTIMIZE TABLE. We already have a check for ALTER TABLE
and CREATE INDEX to preserve the value on table recreate. We should be able to
add an additional check for OPTIMIZE TABLE to preserve the next value.

In case of low memory sort buffer QUICK_INDEX_MERGE_SELECT creates
temporary file where is stores row ids which meet QUICK_SELECT ranges
except of clustered pk range, clustered range is processed separately.
In init_read_record we check if temporary file is used and choose
appropriate record access method. It does not take into account that
temporary file contains partial result in case of QUICK_INDEX_MERGE_SELECT
with clustered pk range.
The fix is always to use rr_quick if QUICK_INDEX_MERGE_SELECT
with clustered pk range is used.

Problem: When GET_FORMAT() is called two times from the upper
level function (e.g. LEAST in the bug report), on the second
call "res= args[0]->val_str(...)" and str point to the same
String object.
1. Fix: changing the order from
- get val_str into tmp_value then convert to str
to
- get val_str into str then convert to tmp_value
The new order is more correct: the purpose of "str" parameter
is exactly to call val_str() for arguments.
The purpose of String class members (like tmp_value) is to do further
actions on the result.
Doing it in the other way around give unexpected surprises.
2. Using str_value instead of str to do padding, for the same reason.

There was a missed corner case in the partitioning
handler, which caused the next_insert_id to be changed
in the second level handlers (i.e the hander of a partition),
which caused this debug assertion.
The solution was to always ensure that only the partitioning
level generates auto_increment values, since if it was done
within a partition, it may fail to match the partition
function.
mysql-test/suite/parts/inc/partition_auto_increment.inc:
Added tests

mysql-test/suite/parts/r/partition_auto_increment_myisam.result:
updated results
sql/ha_partition.cc:
In <engine>::write_row the auto_inc value is generated
through handler::update_auto_increment (which calls <engine>::get_auto_increment() if needed).
If:
* INSERT_ID was set to 0
* it was updated to 0 by 'INSERT ... ON DUPLICATE KEY UPDATE' and changed partitions for the row
Then it would try to generate a auto_increment value in the
<engine for a specific partition>::write_row, which will
trigger the assert.
So the solution is to prevent this by,
in ha_partition::write_row set auto_inc_field_not_null and
add MODE_NO_AUTO_VALUE_ON_ZERO
in ha_partition::update_row (when changing partition) temporary
set table->next_number_field to NULL which calling the
partitions ::write_row().
