C.1.1. Changes in MySQL 5.1.40

The InnoDB Plugin is included in source and binary distributions,
except RHEL3, RHEL4, SuSE 9 (x86, x86_64, ia64), and generic Linux
RPM packages. It also does not work for FreeBSD 6 and HP-UX or for
Linux on S/390, PowerPC and generic ia64.

For further details on the InnoDB Plugin see

http://dev.mysql.com/doc/refman/5.1/en/news-5-1-38.html


Bugs fixed:

* Incompatible Change: In binary installations of MySQL, the
supplied binary-configure script would start and configure
MySQL, even when request help on the command with the --help
command-line option. The --help, if provided, will no longer
start and install the server.
(Bug#30954: http://bugs.mysql.com/30954)

* Partitioning: When reorganizing partitions, not all affected
subpartitions were removed prior to renaming. One way in which
the issue was visible was that attempting to reorganize two
partitions into a single partition having the same name as one
of the original partitions could lead to a crash of the
server. (Bug#47029: http://bugs.mysql.com/47029)
See also Bug#45961: http://bugs.mysql.com/45961,
Bug#43729: http://bugs.mysql.com/43729.

* Partitioning: An online or fast ALTER TABLE of a partitioned
table could leave behind temporary files in the database
directory. (Bug#46483: http://bugs.mysql.com/46483)

* Partitioning: When performing an INSERT ... SELECT into a
partitioned table, read_buffer_size bytes of memory were
allocated for every partition in the target table, resulting
in consumption of large amounts of memory when the table had
many partitions (more than 100).
This fix changes the method used to estimate the buffer size
required for each partition and limits the total buffer size
to a maximum of approximately 10 times read_buffer_size.
(Bug#45840: http://bugs.mysql.com/45840)

* Partitioning: Inserting negative values into an AUTO_INCREMENT
column of a partitioned table could lead to apparently
unrelated errors or a crash of the server.
(Bug#45823: http://bugs.mysql.com/45823)

* Partitioning: Unnecessary calls were made in the server code
for performing bulk inserts on partitions for which no inserts
needed to be made. (Bug#35845: http://bugs.mysql.com/35845)
See also Bug#35843: http://bugs.mysql.com/35843.

* Replication: Performing ALTER TABLE ... DISABLE KEYS on a
slave table caused row-based replication to fail.
(Bug#47312: http://bugs.mysql.com/47312)

* Replication: BEGIN statements were not included in the output
of mysqlbinlog. (Bug#46998: http://bugs.mysql.com/46998)

* Replication: When using row-based replication, importing a
dump made with mysqldump and replicating a row with an
AUTO_INCREMENT column set to 0, with NO_AUTO_VALUE_ON_ZERO
active on the master, the row was inserted successfully on the
master; however any setting for NO_AUTO_VALUE_ON_ZERO was
ignored on the slave. When the AUTO_INCREMENT column was
incremented, this caused replication to fail on the slave due
to a duplicate key error. In some cases it could also cause
the slave to crash. (Bug#45999: http://bugs.mysql.com/45999)

* Replication: Concurrent transactions that inserted rows into a
table with an AUTO_INCREMENT column could break
statement-based or mixed-format replication error 1062
Duplicate entry '...' for key 'PRIMARY' on the slave. This was
especially likely to happen when one of the transactions
activated a trigger that inserted rows into the table with the
AUTO_INCREMENT column, although other conditions could also
cause the issue to manifest.
(Bug#45677: http://bugs.mysql.com/45677)

* Replication: By default, all statements executed by the
mysql_upgrade program on the master are written to the binary
log, then replicated to the slave. In some cases, this can
result in problems; for example, it attempted to alter log
tables on replicated databases (this failed due to logging
being enabled).
As part of this fix, a new mysql_upgrade option --write-binlog
is added. Its inverse, --skip-write-binlog, can be used to
disable binary logging while the upgrade is in progress.
(Bug#43579: http://bugs.mysql.com/43579)

* Replication: On the master, if a binary log event is larger
than max_allowed_packet, the error message
ER_MASTER_FATAL_ERROR_READING_BINLOG is sent to a slave when
it requests a dump from the master, thus leading the I/O
thread to stop. On a slave, the I/O thread stops when
receiving a packet larger than max_allowed_packet.
In both cases, however, there was no Last_IO_Error reported,
which made it difficult to determine why the slave had stopped
in such cases. Now, Last_IO_Error is reported when
max_allowed_packet is exceeded, and provides the reason for
which the slave I/O thread stopped.

* API: The fix for Bug#24507: http://bugs.mysql.com/24507 could
lead in some cases to client application failures due to a
race condition. Now the server waits for the "dummy" thread to
return before exiting, thus making sure that only one thread
can initialize the POSIX threads library.
(Bug#42850: http://bugs.mysql.com/42850)

* The pthread_cond_wait() implementations for Windows could
deadlock in some rare circumstances.
(Bug#47768: http://bugs.mysql.com/47768)

* Solaris binary packages now are compiled with -g0 rather than
-g. (Bug#47137: http://bugs.mysql.com/47137)

* EXPLAIN caused a server crash for certain valid queries.
(Bug#47106: http://bugs.mysql.com/47106)

* The configure option --without-server did not work.
(Bug#46980: http://bugs.mysql.com/46980)

* Failed multiple-table DELETE statements could raise an
assertion. (Bug#46958: http://bugs.mysql.com/46958)

* When creating a new instance on Windows using mysqld-nt and
the --install parameter, the value of the service would be set
incorrectly, resulting in a failure to start the configured
service. (Bug#46917: http://bugs.mysql.com/46917)

* The server crashed when re-using outer column references in
correlated subqueries when the enclosing query used a temp
table. (Bug#46791: http://bugs.mysql.com/46791)

* Assertion failure could result from repeated execution of a
stored procedure containing an incorrect query with a
subselect. (Bug#46629: http://bugs.mysql.com/46629)

* The server ignored the setting of sync_frm for CREATE TABLE
... LIKE. (Bug#46591: http://bugs.mysql.com/46591)

* An attempt to create a table with the same name as an existing
view could cause a server crash.
(Bug#46384: http://bugs.mysql.com/46384)

* A parser problem prevented properly stripping backquotes from
an argument to a user-defined function (UDF). If the UDF was
in an ORDER BY clause, its name would not be properly resolved
against an alias with the same name in the select list.
(Bug#46259: http://bugs.mysql.com/46259)

* Certain SELECT statements containing DISTINCT, GROUP BY, and
HAVING clauses could hang in an infinite loop.
(Bug#46159: http://bugs.mysql.com/46159)

* CREATE TEMPORARY TABLE failed for InnoDB tables on systems
with case-insensitive file systems when lower_case_table_names
= 2 and the pathname of the temporary file directory contained
uppercase characters. (Bug#45638: http://bugs.mysql.com/45638)

* Appending values to an ENUM or SET definition is a metadata
change for which ALTER TABLE need not rebuild the table, but
it was being rebuilt anyway.
(Bug#45567: http://bugs.mysql.com/45567)

* The socket system variable was unavailable on Windows.
(Bug#45498: http://bugs.mysql.com/45498)

* When re-installing MySQL on Windows on a server that has a
data directory from a previous MySQL installation, the
installer would fail to identify the existence of the
installation and the password configured for the root user.
(Bug#45200: http://bugs.mysql.com/45200)

* Client flags were incorrectly initialized for the embedded
server, causing several tests in the jp test suite to fail.
(Bug#45159: http://bugs.mysql.com/45159)

* SELECT ... WHERE ... IN (NULL, ...) was executed using a full
table scan, even if the same query without the NULL used an
efficient range scan. (Bug#44139: http://bugs.mysql.com/44139)
See also Bug#18360: http://bugs.mysql.com/18360.

* LOAD DATA INFILE statements were written to the binary log in
such a way that parsing problems could occur when re-executing
the statement from the log.
(Bug#43746: http://bugs.mysql.com/43746)

* Selecting from the process list in the embedded server caused
a crash. (Bug#43733: http://bugs.mysql.com/43733)

* Attempts to enable large_pages with a shared memory segment
larger than 4GB caused a server crash.
(Bug#43606: http://bugs.mysql.com/43606)

* A test for stack growth failed on some platforms, leading to
server crashes. (Bug#42213: http://bugs.mysql.com/42213)

* The mysql-stress-test.pl test script was missing from the
noinstall packages on Windows.
(Bug#41546: http://bugs.mysql.com/41546)

* Privileges for SHOW CREATE VIEW were not being checked
correctly. (Bug#35996: http://bugs.mysql.com/35996)

* Different invocations of CHECKSUM TABLE could return different
results for a table containing columns with spatial data
types. (Bug#35570: http://bugs.mysql.com/35570)

* myisamchk performed parameter value casting at startup that
generated unnecessary warning messages.
(Bug#33785: http://bugs.mysql.com/33785)

* When building MySQL on Windows from source, the
WITH_BERKELEY_STORAGE_ENGINE option would fail to configure
BDB support correctly.
