The "get_master_version_and_clock(...)" function in sql/slave.cc ignores
error and passes directly when queries fail, or queries succeed
but the result retrieved is empty.
The "get_master_version_and_clock(...)" function should try to reconnect master
if queries fail because of transient network problems, and fail otherwise.
The I/O thread should print a warning if the some system variables do not
exist on master (very old master)

There is an inconsistency with DROP DATABASE|TABLE|EVENT IF EXISTS and
CREATE DATABASE|TABLE|EVENT IF NOT EXISTS. DROP IF EXISTS statements are
binlogged even if either the DB, TABLE or EVENT does not exist. In
contrast, Only the CREATE EVENT IF NOT EXISTS is binlogged when the EVENT
exists.
This patch fixes the following cases for all the replication formats:
CREATE DATABASE IF NOT EXISTS.
CREATE TABLE IF NOT EXISTS,
CREATE TABLE IF NOT EXISTS ... LIKE,
CREAET TABLE IF NOT EXISTS ... SELECT.
sql/sql_insert.cc:
Part of the code was moved from the create_table_from_items to select_create::prepare.
When replication is row based, CREATE TABLE IF NOT EXISTS.. SELECT is binlogged if the table exists.

This is an alternative patch that instead of allowing RECREATE TABLE
on TRUNCATE TABLE it implements reset_auto_increment that is called
after delete_all_rows.

With ibmdb2i_create_index_option set to 1, creating an IBMDB2I table
with a primary key should produce an additional index that uses EBCDIC
hexadecimal sorting. However, this does not work. Adding indexes that
are not primary keys does work. The ibmdb2i_create_index_option should
be honoured when creating a table with a primary key.
This patch adds code to the create() function to check for the value
of the ibmdb2i_create_index_option variable and, when appropriate, to
generate a *HEX-based shadow index in DB2 for the primary key. Previously
this behavior was limited to secondary indexes.
Additionally, this patch restricts the creation of shadow indexes to
cases in which a non-*HEX sort sequence is used, as the documentation
for ibmdb2i_create_index_option describes. Previously, the shadow index
would in some cases be created even when the MySQL-specific index used
*HEX sorting, leading to redundant indexes.
Finally, the code used to generate the list of fields for indexes
and the code used to generate the SQL statement for the shadow
indexes has been refactored into individual functions.

Had attempted to disable this test on Windows only, but the nature of this bug
does not allow for this. The master.opt file is processed before anything in
in the actual test. As a result, we must use disabled.def files to ensure
these tests are skipped on the problematic platforms.
Removed Windows-only code and updated the proper disabled.def files accordingly.
Some collations were causing IBMDB2I to report
inaccurate key range estimations to the optimizer
for LIKE clauses that select substrings. This can
be seen by running EXPLAIN. This problem primarily
affects multi-byte and unicode character sets.
This patch involves substantial changes to several
modules. There are a number of problems with the
character set and collation handling. These problems
have been or are being fixed, and a comprehensive
test has been included which should provide much
better coverage than there was before. This test
is enabled only for IBM i 6.1, because that version
has support for the greatest number of collations.

storage/ibmdb2i/db2i_conversion.cc:
Bug#45803 Inaccurate estimates for partial key values with IBMDB2I
- Added support in convertFieldChars to enable records_in_range
to determine how many substitute characters were inserted and
to suppress conversion warnings.
- Fixed bug which was causing all multi-byte and Unicode fields
to be created as UTF16 (CCSID 1200) fields in DB2. The corrected
code will now create UCS2 fields as UCS2 (CCSID 13488), UTF8
fields (except for utf8_general_ci) as UTF8 (CCSID 1208), and
all other multi-byte or Unicode fields as UTF16. This will only
affect tables that are newly created through the IBMDB2I storage
engine. Existing IBMDB2I tables will retain the original CCSID
until recreated. The existing behavior is believed to be
functionally correct, but it may negatively impact performance
by causing unnecessary character conversion. Additionally, users
accessing IBMDB2I tables through DB2 should be aware that mixing
tables created before and after this change may require extra type
casts or other workarounds. For this reason, users who have
existing IBMDB2I tables using a Unicode collation other than
utf8_general_ci are encouraged to recreate their tables (e.g.
ALTER TABLE t1 ENGINE=IBMDB2I) in order to get the updated CCSIDs
associated with their DB2 tables.
- Improved error reporting for unsupported character sets by forcing
a check for the iconv conversion table at table creation time,
rather than at data access time.

Bug#45803 Inaccurate estimates for partial key values with IBMDB2I
Fix to set errno when iconv fails.
storage/ibmdb2i/db2i_rir.cc:
Bug#45803 Inaccurate estimates for partial key values with IBMDB2I
Significant improvements were made to the records_in_range code
that handles partial length string data in keys for optimizer plan
estimation. Previously, to obtain an estimate for a partial key
value, the implementation would perform any necessary character
conversion and then attempt to determine the unpadded length of
the partial key by searching for the minimum or maximum sort
character. While this algorithm was sufficient for most single-byte
character sets, it did not treat Unicode and multi-byte strings
correctly. Furthermore, due to an operating system limitation,
partial keys having UTF8 collations (ICU sort sequences in DB2)
could not be estimated with this method.
With this patch, the code no longer attempts to explicitly determine
the unpadded length of the key. Instead, the entire key is converted
(if necessary), including padding, and then passed to the operating
system for estimation. Depending on the source and target character
sets and collations, additional logic is required to correctly
handle cases in which MySQL uses unconvertible or differently
-weighted values to pad the key. The bulk of the patch exists
to implement this additional logic.
storage/ibmdb2i/ha_ibmdb2i.h:
Bug#45803 Inaccurate estimates for partial key values with IBMDB2I
The convertFieldChars declaration was updated to support additional
optional behaviors.
timeout
In STMT and MIXED modes, a statement that changes both non-transactional and
transactional tables must be written to the binary log whenever there are
changes to non-transactional tables. This means that the statement gets into the
binary log even when the changes to the transactional tables fail. In particular
, in the presence of a failure such statement is annotated with the error number
and wrapped in a begin/rollback. On the slave, while applying the statement, it
is expected the same failure and the rollback prevents the transactional changes
to be persisted.
Unfortunately, statements that fail due to concurrency issues (e.g. deadlocks,
timeouts) are logged in the same way causing the slave to stop as the statements
are applied sequentially by the SQL Thread. To fix this bug, we automatically
ignore concurrency failures on the slave. Specifically, the following failures
are ignored: ER_LOCK_WAIT_TIMEOUT, ER_LOCK_DEADLOCK and ER_XA_RBDEADLOCK.
Creating an IBMDB2I table with the macce character set
is successful, but any attempt to insert data into the
table was failing.
This was happening because the character set name "macce"

Some collations--including cp1250_czech_cs,latin2_czech_cs,
ucs2/utf8_czech_ci, ucs2/utf8_danish_ci--are not being
sorted correctly by the IBMDB2I storage engine. This
was being caused because the sort order used by DB2 is
incompatible with the order expected by MySQL.
This patch removes support for the cp1250_czech_cs and
latin2_czech_cs collations because it has been determined
that the sort order used by DB2 is incompatible with the
order expected by MySQL. Users needing a czech collation
with IBMDB2I are encouraged to use a Unicode-based collation
instead of these single-byte collations. This patch also
modifies the DB2 sort sequence used for ucs2/utf8_czech_ci
and ucs2/utf8_danish_ci collations to better match the
sorting expected by MySQL. This will only affect indexes
or tables that are newly created through the IBMDB2I storage
engine. Existing IBMDB2I tables will retain the old sort
sequence until recreated.

2. I am not able to check the correctness of this patch

So it could happen that the new test fails somewhere.
Large transactions and statements may corrupt the binary log if the size of the
cache, which is set by the max_binlog_cache_size, is not enough to store the
the changes.
In a nutshell, to fix the bug, we save the position of the next character in the
cache before starting processing a statement. If there is a problem, we simply
restore the position thus removing any effect of the statement from the cache.
Unfortunately, to avoid corrupting the binary log, we may end up loosing changes
on non-transactional tables if they do not fit in the cache. In such cases, we
store an Incident_log_event in order to stop the slave and alert users that some
changes were not logged.
Precisely, for every non-transactional changes that do not fit into the cache,
we do the following:
a) the statement is *not* logged
b) an incident event is logged after committing/rolling back the transaction,
if any. Note that if a failure happens before writing the incident event to
the binary log, the slave will not stop and the master will not have reported
any error.
c) its respective statement gives an error
For transactional changes that do not fit into the cache, we do the following:
a) the statement is *not* logged
b) its respective statement gives an error
To work properly, this patch requires two additional things. Firstly, callers to
MYSQL_BIN_LOG::write and THD::binlog_query must handle any error returned and
take the appropriate actions such as undoing the effects of a statement. We
already changed some calls in the sql_insert.cc, sql_update.cc and sql_insert.cc
modules but the remaining calls spread all over the code should be handled in
BUG#37148. Secondly, statements must be either classified as DDL or DML because
DDLs that do not get into the cache must generate an incident event since they
cannot be rolled back.

mysqlbinlog --database parameter was being ignored when processing

This patch addresses this by deploying a call to shall_skip_database

the database). All other rows events referencing the table id for the
filtered map event, will also be skipped.
client/mysqlbinlog.cc:
Added shall_skip_database call to the part of the code that handles
Table_map_log_events. It inspects the database name and decides whether

next events referencing the table id in the table map event, will also
be filtered.

Item_field::update_null_value) to suppress unwanted warnings
from Item_func_get_system_var::val_int() calls on non-numeric

In order to better support the usage of
IBMDB2I tables from within RPG programs,
the storage engine should ensure that the
RCDFMT name is consistent and predictable
for DB2 tables.
This patch appends a "RCDFMT <name>"
clause to the CREATE TABLE statement
that is passed to DB2. <name> is
generated from the original name of
the table itself. This ensures a
consistent and deterministic mapping
from the original table.
For the sake of simplicity only
the alpha-numeric characters are
preserved when generating the new
name, and these are upper-cased;
other characters are replaced with
an underscore (_). Following DB2
system identifier rules, the name
always begins with an alpha-character
and has a maximum of ten characters.
If no usable characters are found in
the table name, the name X is used.

"freeing items"
The calculation of the table map log event in the event constructor
was one byte shorter than what would be actually written. This would
lead to a mismatch between the number of bytes written and the event
end_log_pos, causing bad event alignment in the binlog (corrupted
binlog) or in the transaction cache while fixing positions
(MYSQL_BIN_LOG::write_cache). This could lead to impossible to read
binlog or even infinite loops in MYSQL_BIN_LOG::write_cache.
This patch addresses this issue by correcting the expected event
length in the Table_map_log_event constructor, when the field metadata
size exceeds 255.
sql/log_event.cc:
Added the extra byte as net_store_length imposes.
In the output from mysqlbinlog, incident log events were
represented as just a comment. Since the incident log event
represents an incident that could cause the contents of the
database to change without being logged to the binary log,
it means that if the SQL is applied to a server, it could
potentially lead to that the databases are out of sync.
In order to handle that, this patch adds the statement "RELOAD
DATABASE" to the SQL output for the incident log event. This will
require a DBA to edit the file and handle the case as apropriate
before applying the output to a server.

1. Replace waiting of SQL thread stop by waiting of SQL error on slave and stopped
SQL thread.
2. Remove debug code because it already implemented in MTR2.
Respectively, replaced "--exec diff" by "--diff_files" which is a mysqltest command to run a
non-operating system specific diff. Removed the file rpl_000015-slave.sh as it is not
necessary in the new MTR.
Turned off autocommit at the start of this test per Innobase recommendation.
Noted significant reduction in run time for this test w/ a minor increase in other tests' run-times.
In order to define the --slave-load-tmpdir, the init_relay_log_file()
was calling fn_format(MY_PACK_FILENAME) which internally was indirectly
calling strmov_overlapp() (through pack_dirname) and the following
warning message was being printed out while running in Valgrind:
"source and destination overlap in strcpy".
We fixed the issue by removing the flag MY_PACK_FILENAME as it was not
necessary. In a nutshell, with this flag the function fn_format() tried
to replace a directory by either "~", "." or "..". However, we wanted
exactly to remove such strings.
In this patch, we also refactored the functions init_relay_log_file()
and check_temp_dir(). The former was refactored to call the fn_format()
with the flag MY_SAFE_PATH along with the MY_RETURN_REAL_PATH, in order
to avoid issues with long directories and return an absolute path,
respectively. The flag MY_SAFE_UNPACK_FILENAME was removed too as it was
responsible for removing "~", "." or ".." only from the file parameter
and we wanted to remove such strings from the directory parameter in
the fn_format(). This result is stored in an rli variable, which is then
processed by the other function in order to verify if the directory exists
and if we are able to create files in it.

Mysql server crashes because unsafe statements warning is wrongly elevated to error,
which is set the error status of Diagnostics_area of the thread in THD::binlog_query().
Yet the caller believes that binary logging shouldn't touch the status, so it will
set the status also later by my_ok(), my_error() or my_message() seperately
according to the execution result of the statement or transaction.
But the status of Diagnostics_area of the thread is allowed to set only once.

It is impossible to roll back a mixed engines transaction when one of the engine is

LOAD_FILE
LOAD_FILE is not safe to replicate in STATEMENT mode, because it
depends on a file (which is loaded on master and may not exist in
slave(s)). This leads to scenarios on which the slave replicates the
statement with 'load_file' and it will try to load the file from local
file system. Given that the file may not exist in the slave filesystem
the operation will not succeed (probably returning NULL), causing
master and slave(s) to diverge. However, when using MIXED mode
replication, this can be made to work, if the statement including
LOAD_FILE is marked as unsafe, triggering a switch to ROW mode,
meaning that the contents of the file are written to binlog as row
events. Consequently, the contents from the file in the master will
reach the slave via the binlog.
This patch addresses this bug by marking the load_file function as
unsafe. When in mixed mode and when LOAD_FILE is issued, there will be
a switch to row mode. Furthermore, when in statement mode, the
LOAD_FILE will raise a warning that the statement is unsafe in that
mode.

Compiling with debug and assigning an invalid directory to --slave-load-tmpdir
was crashing the slave due to the following assertion DBUG_ASSERT(! is_set() ||
can_overwrite_status). This assertion assumes that a thread can change its
state once (i.e. ok,error, etc) before aborting, cleaning/resuming or completing
its execution unless the overwrite flag (i.e. can_overwrite_status) is true.
The Append_block_log_event::do_apply_event which is responsible for creating
temporary file(s) was not cleaning the thread state. Thus a failure while
trying to create a file in an invalid temporary directory was causing the crash.
To fix the problem we check if the temporary directory is valid before starting
the SQL Thread and reset the thread state before creating a file in
Append_block_log_event::do_apply_event.
mysql.procs_priv table itself does not get replicated.
Inserting routine privilege record into mysql.procs_priv table
is triggered by creating function/procedure statements
according to current user's privileges.
Because the current user of SQL thread has GLOBAL_ACL,
which doesn't need any check mysql.procs_priv privilege
when create/alter/execute routines.
Corresponding GLOBAL_ACL privilege user
doesn't insert routine privilege record into
mysql.procs_priv when creating a routine.
Fixed by switching the current user of SQL thread to definer user if
the definer user exists on slave.
That populates procs_priv, otherwise to keep the SQL thread
user and procs_priv remains unchanged.

The problem is issued because we set wrong start position and stop position of query string into binlog.
That two values are stored as part of head info of query string.
When we parse binlog, we first get position values then get the query string according position values.
But seems that two values are not calculated correctly after the parse of Yacc.
We don't want to touch so much of yacc because it may influence other codes.
So just add one space after 'INTO' key word when parsing.

The method to purge binary log files produces different results in some platforms.
The reason is that the purge time is calculated based on table modified time and
that can't guarantee to purge master-bin.000002 in all platforms.(eg. windows)
Use a new way that sets the time to purge binlog file 1 second after the last
modified time of master-bin.000002.

The problem is that creating a event could fail if the value of
the variable server_id didn't fit in the originator column of
the event system table. The cause is two-fold: it was possible
to set server_id to a value outside the documented range (from
0 to 2^32-1) and the originator column of the event table didn't
have enough room for values in this range.
The log tables (general_log and slow_log) also don't have a proper
column type to store the server_id and having a large server_id
value could prevent queries from being logged.
The solution is to ensure that all system tables that store the
server_id value have a proper column type (int unsigned) and that
the variable can't be set to a value that is not within the range.

The method to purge binary log files produces different results in some platforms.
The reason is that the purge time is calculated based on table modified time and
that can't guarantee to purge master-bin.000002 in all platforms.(eg. windows)
Use a new way that sets the time to purge binlog file 1 second after the last modified time of master-bin.000002.
That can be sure that the file is always deleted in any platform.

mysql-test/suite/rpl/t/rpl_rotate_logs.test:
Change 'purge time' 1 sencond after the last modified time of master-bin.000002.
The reason of the bug is in that the test makes a trick with relay log files and
did not reset fully at the end.
If mtr does not restart the test the new SQL thread tried to work with the old time
session data.
Fixed with deploying RESET slave at the clean-up.
mysql-test/suite/binlog/t/binlog_auto_increment_bug33029.test:
adding RESET slave to force active mi and rli data struct to be reset.
The slave SQL thread will deal with a fresh structures each time it restarts.
When using mixed mode the record values stored inside the storage
engine differed from the ones computed from the row event. This
happened because the prepare_record function was calling
empty_record macro causing some don't care bits to be left set.
Replacing the empty_record plus explicitly setting defaults with
restore_record to restore the record default values fixes this.
When binlog_format is STATEMENT and the statement is unsafe before,
the unsafe warning/error message was issued without checking
whether the SQL_LOG_BIN was turned on or not.
Fixed with adding a sql_log_bin_toplevel flag in THD to check
whether SQL_LOG_BIN is ON in current session whatever the current is in sp or not.

slave.
In mixed mode, if we create a temporary table and do some update which switch to ROW format,
the format will keep in ROW format until the session ends or the table is dropped explicitly.
When the session ends, the temp table is dropped automaticly at cleanup time.
but it checks only current binlog format and so skip insertion of DROP TABLE instructions into binlog.
So the temp table can't be dropped correctly at slave.
Our solution is that when closing temp tables at cleanup time we check both binlog format and binlog mode,
and we could write DROP TABLE instructions into binlog if current binlog format is ROW but in MIX mode.

If secure-file-priv was set on slave, it became unable to execute

This patch fixes the issue by ignoring this security restriction

There were so many changes into mtr (this is the new mtr coming) that I rather
copied mtr from 6.0-main here (at least this one knows how to run Maria tests).
I also fixed suite/maria tests to be accepted by the new mtr.
mysys/thr_mutex.c:
adding DBUG_PRINT here, so that we can locate where the warning is issued.
The test case relies on binlog entries for assertion. The problem is that the
binlog does not get cleaned in pushbuild between tests, resulting in extra
entries in the result file, causing the test to fail.
This fix adds a reset master at the beginning of the test, so that we get a
clean binlog file.
Some errors that cause the slave SQL thread to stop are not shown in the
Slave_SQL_Error column of "SHOW SLAVE STATUS". Instead, the error is only
in the server's error log.
That makes it difficult to analyze the error for the user. One example of an error
that stops the slave but is not shown by "SHOW SLAVE STATUS" is when @@global.init_slave
is set incorrectly (e.g., it contains something that is not valid SQL).
Three failures were not correctly reported:
1 - Failures during slave thread initialization
2 - Failures while initializing the relay log position right after
starting the slave thread.
3 - Failures while processing queries passed through the init_slave
option.
This patch fixes the issues by reporting the errors through relay-info->report.
TRUNCATE TABLE fails to replicate when stmt-based binlogging is not supported.

There is an inconsistency with DROP DATABASE IF EXISTS, DROP
TABLE IF EXISTS and DROP VIEW IF EXISTS: those are binlogged even
if the DB or TABLE does not exist, whereas DROP PROCEDURE IF
EXISTS does not. It would be nice or at least consistent if DROP
PROCEDURE/STATEMENT worked the same too.
Fixed DROP PROCEDURE|FUNCTION IF EXISTS by adding a call to
write_bin_log in mysql_execute_command. Checked also if all
documented "DROP (...) IF EXISTS" get binlogged. Left out DROP
SERVER IF EXISTS because it seems that it only gets binlogged when
using row event (see BUG#25705).
The problem is that a unfiltered user query was being passed as
the format string parameter of sql_print_warning which later
performs printf-like formatting, leading to crashes if the user
query contains formatting instructions (ie: %s). Also, it was
using THD::query as the source of the user query, but this
variable is not meaningful in some situations -- in a delayed
insert, it points to the table name.
The solution is to pass the user query as a parameter for the
format string and use the function parameter query_arg as the
source of the user query.

Path composition for the relay log file that is stored into the relay index
file was not correct for windows.
mysql-test language does not provide primitives for portable path composition.
Fixed with storing only the basename part of the external "fake" relay log into
the relay index file.
Safety of removal of the dirname part of the relaylog is provided by logics of
`setup_fake_relay_log' that places the fake file into @@datadir directory.

TRUNCATE TABLE fails to replicate when stmt-based binlogging is not supported.
There were two separate problems with the code, both of which are fixed with
this patch:
1. An error was printed by InnoDB for TRUNCATE TABLE in statement mode when
the in isolation levels READ COMMITTED and READ UNCOMMITTED since InnoDB
does permit statement-based replication for DML statements. However,
the TRUNCATE TABLE is not transactional, but is a DDL, and should therefore
be allowed to be replicated as a statement.
2. The statement was not logged in mixed mode because of the error above, but
the error was not reported to the client.
This patch fixes the problem by treating TRUNCATE TABLE a DDL, that is, it is
always logged as a statement and not reporting an error from InnoDB for TRUNCATE
TABLE.

sql/sql_base.cc:
Correcting setting of capabilities flags to make the comparison with 0

sql/sql_delete.cc:
Re-organizing code to ensure that TRUNCATE TABLE is logged in statement
format and that row format is not used unless there are rows to log (which
there are not when delete_all_rows() is called, so this has to be logged
as a statement).
Documented behaviour was broken by the patch for bug 33699
that actually is not a bug.
This fix reverts patch for bug 33699 and reverts the

The bug happened because filtering-out a STMT_END_F-flagged event so that
the transaction COMMIT finds traces of incomplete statement commit.
Such situation is only possible with ndb circular replication. The filtered-out
rows event is one that immediately preceeds the COMMIT query event.
Fixed with deploying an the rows-log-event statement commit at executing
of the transaction COMMIT event.
Resources that were allocated by other than STMT_END_F-flagged event of
the last statement are clean up prior execution of the commit logics.
mysql-test/suite/rpl_ndb/t/disabled.def:
re-enabling two tests.
sql/log_event.cc:
Adding the statement cleanup to execute at the transaction commit time.
The statement might not be ended with execution of STMT_END_F-flagged event because of
the event was filtered out by SERVER_ID rules.
Small refactoring for Rows_log_event::do_update_pos() to be split on two parts:
the statement commit that releases its execution time allocated resources, and
the relay log update.
