printstack() being present
When Bug#47391 was fixed, no assumption was made that support
for Solaris 8 was needed. Solaris 8 lacks printstack(), and
the build breaks because of this.
This patch adds a test for the presence of printstack() to
configure.in for 5.0, and uses HAVE_PRINTSTACK to make
decisions rather than the __sun define.
The 'rpl_get_master_version_and_clock' test verifies if the slave I/O
thread tries to reconnect to master when it tries to get the values of
the UNIX_TIMESTAMP, SERVER_ID from master under network disconnection.
So the master server is restarted for making the transient network
disconnection, during the period the COM_REGISTER_SLAVE failures are
produced in server log file when the slave I/O thread tries to
register on master.
To fix the problem, suppress COM_REGISTER_SLAVE failures in server log
file by mtr suppression, because they are expected.
MySQL's hash functions MD5 and SHA relied on the somewhat slow
sprintf function to convert the digests to hex representations.
This patch replaces the sprintf with a specific and inline hex
conversion function.

Bug #45856 can't switch from binlog_format=row to mix with open tmp tbl
If binlog_format=MIXED, there are open temporary tables, an unsafe statement
is executed, and the user issues 'SET @@session.binlog_format = STATEMENT',
then subsequent DML statements will be written in row format despite
binlog_format=STATEMENT. Because the binlog format can't be reset to
statement based by 'reset_current_stmt_binlog_row_based' function.
If binlog_format=ROW, there are open temporary tables, and an unsafe statement
is executed, then the statement 'SET @@session.binlog_format = MIXED' generates
the error:
"Cannot switch out of the row-based binary log format when the session has open
temporary tables"
However, it is safe to switch to MIXED mode because events in row format are allowed.
To fix the above two problems, generate ER_TEMP_TABLE_PREVENTS_SWITCH_OUT_OF_RBR
and forbid switching from MIXED or ROW to STATEMENT when there are open temp
tables and we are logging in row format. There is no error in any other case.
When replicating from 4.1 master to 5.0 slave START SLAVE UNTIL can stop too late.
The necessary in calculating of the beginning of an event the event's length
did not correspond to the master's genuine information at the event's execution time.
That piece of info was changed at the event's relay-logging due to binlog_version<4 event
conversion by IO thread.
Fixed with storing the master genuine Query_log_event size into a new status
variable at relay-logging of the event. The stored info is extacted at the event
execution and participate further to caclulate the correct start position of the event
in the until-pos stopping routine.
The new status variable's algorithm will be only active when the event comes
from the master of version < 5.0 (binlog_version < 4).

In RBR, DDL statement will change binlog format to non row-based
format before it is binlogged, but the binlog format was not be
restored, and then manipulating a temporary table can not reset binlog
format to row-based format rightly. So that the manipulated statement
is binlogged with statement-based format.
To fix the problem, restore the state of binlog format after the DDL
statement is binlogged.
cant find record
Some engines return data for the record. Despite the fact that
the null bit is set for some fields, their old value may still in
the row. This can happen when unpacking an AI from the binlog on
top of a previous record in which a field is set to NULL, which
previously contained a value. Ultimately, this may cause the
comparison of records to fail when the slave is doing an index or
range scan.
We fix this by deploying a call to reset() for each field that is
set to null while unpacking a row from the binary log.
Furthermore, we also add mixed mode test case to cover the
scenario where updating and setting a field to null through a
Query event and later searching it through a rows event will
succeed.
Finally, we also change the reset() method, from Field_bit class,
so that it takes into account bits stored among the null bits and
not only the ones stored in the record.
check_access() returning false for a database does not
guarantee that the access is granted to it.
This wrong condition in filling the INFORMATION_SCHEMA
tables causes extra tables to be returned to the user
even if he has no rights to see them.
Fixed by correcting the condition.
Resetting the master before stopping the slave was generating the message
"[ERROR] Slave I/O: Got fatal error 1236 from master when reading data from
binary log: 'could not find next log', Error_code: 1236". In consequence,
the test case was failing because the message had not been suppressed.
To circumvent the failure, we rewrote the test stopping the slave before
resetting the master. We prefer this alternative rather than suppressing
the message.
Several items said to be deprecated in the 4.1 manual

warnings when these items are used, and warns the user
that the items will be removed in MySQL 5.6.

The test case injects an error in the server by deleting the
temporary file that it uses during the load data statement
execution. The error consisted of closing, deleting and setting
the file descriptor to -1 right before calling mysql_file_write.
Although, this error injection seems to work OK in Unix like
environments, in Windows, this would cause the server to hit an
assertion in 'my_get_open_flags':
DBUG_ASSERT(fd >= MY_FILE_MIN && fd < (int)my_file_limit)
We fix this by changing the error injection to just call the
macro my_delete_allow_opened, instead of the close + delete + set
fd=-1. The macro deletes the file and is platform
independent. Additionally, this required some changes to how the
assertion is handled in the test case to make it cope with this
change.

BUG#44840 - ndbapi compiler warning - type qualifier ignored for function return type
- Remove the "const"
- NOTE! This is an ABI incompatible change for some C++ compilers, NdbApi applications
using any of the four changed functions may need a recompile if it's using dynamic linking.
It is well-known that due to concurrency issues, a slave can become
inconsistent when a transaction contains updates to both transaction and
non-transactional tables in statement and mixed modes.
In a nutshell, the current code-base tries to preserve causality among the
statements by writing non-transactional statements to the txn-cache which
is flushed upon commit. However, modifications done to non-transactional
tables on behalf of a transaction become immediately visible to other
connections but may not immediately get into the binary log and therefore
consistency may be broken.
In general, it is impossible to automatically detect causality/dependency
among statements by just analyzing the statements sent to the server. This
happen because dependency may be hidden in the application code and it is
necessary to know a priori all the statements processed in the context of
a transaction such as in a procedure. Moreover, even for the few cases that
we could automatically address in the server, the computation effort
required could make the approach infeasible.
So, in this patch we introduce the option
- "--binlog-direct-non-transactional-updates" that can be used to bypass
the current behavior in order to write directly to binary log statements
that change non-transactional tables.
The test case was failing because it contained instructions
to close/reopen files, when they were in use. This raises
problems in windows. Example of such instruction:
---exec echo "failure" > $MYSQLD_SLAVE_DATADIR/$file
The test also contains commands that are not platform
agnostic. Example:
--exec cat $MYSQLD_SLAVE_DATADIR/master.backup > \
$MYSQLD_SLAVE_DATADIR/master.info
We fix this by just truncating the necessary file and write
"failure" into it (ie, without closing the file). The
platform specific instruction is removed from the test
case as it seems redundant.
