Препоръчвам на всички с 4.0 и особено на тези с версии преди 4.0.15 да ъпгрейдват веднага.
Пристигнал е на ftp://mysql.online.bg/mysql/Downloads, http://mysql.online.bg еще не се е синхронизирал.
News from the ChangeLog:
Functionality added or changed:
* Write memory allocation information to error log when doing
`mysqladmin debug'. This only works on system that support the
`mallinfo()' call (like newer Linux systems).
* Added the following new server variables to allow more precise
memory allocation: `range_alloc_block_size',
`query_alloc_block_size', `query_prealloc_size',
`transaction_alloc_block_size', and `transaction_prealloc_size'.
* `mysqlbinlog' now reads options files. To make this work one must
now specify `--read-from-remote-server' when reading binary logs
from a MySQL server. (Note that using a remote server is
deprecated and may disappear in future `mysqlbinlog' versions).
* Block `SIGPIPE' also for non-threaded programs. The blocking is
moved from `mysql_init()' to `mysql_server_init()', which is
automatically called on the first call to `mysql_init()'.
* Added `--libs_r' and `--include' options to `mysql_config'.
* New ``>' prompt for `mysql'. This prompt is similar to the `'>'
and `">' prompts, but indicates that an identifier quoted with
backticks was begun on an earlier line and the closing backtick
has not yet been seen.
* Updated `mysql_install_db' to be able to use the local machine's IP
address instead of the host name when building the initial grant
tables if `skip-name-resolve' has been specified in `my.cnf'.
Using this option can be helpful on FreeBSD to avoid thread-safety
problems with the FreeBSD resolver libraries. (Thanks to Jeremy
Zawodny for the patch)
* A documentation change: added a note that when backing up a slave,
one needs to backup the `master.info' and `relay-log.info' files,
and the `SQL-LOAD*' files (which are in the `slave-load-tmpdir'
directory, which defaults to `tmpdir' if unset). All these files
will be needed when the slave resumes replication after you
restore the slave's data.
Bugs fixed:
* Fixed crash of Query Cache on queries which use same table several
times.
* Fixed core dump bug when setting an enum system variable (like
`SQL_WARNINGS') to `NULL'.
* Fixed server crash when running `FLUSH QUERY CACHE'. (Bug #988)
* Extended default timeout in clients on windows from 30 seconds to
1 year. (The timeout that was added in MySQL 4.0.15 was way too
short).
* More "out of memory" checking in range optimiser.
* Fixed and documented problem when setting and using a user
variable in the same `SELECT' statement. (Bug #1194).
* Fixed bug in overrun check for blobs with compressed tables (bug
introduced in 4.0.14). This caused MySQL to regard some correct
tables with blobs to be corrupted. (Bug #770, Bug #1304, and maybe
Bug #1295)
* `SHOW GRANTS' showed `USAGE' instead of real privileges for column
grants when no table grants was given.
* When it wanted to copy a database from the master, `LOAD DATA FROM
MASTER' dropped the corresponding database on the slave, thus
dropping tables which may not have a counterpart on the master, or
tables which may be excluded from replication using
`replicate-*-table' rules. Now `LOAD DATA FROM MASTER' does not
drop the database anymore, it drops only the tables which have a
counterpart on the master and which match the `replicate-*-table'
rules. `replicate-*-db' rules can still be used to include/exclude
a database as a whole from `LOAD DATA FROM MASTER'. A database will
also be included/excluded as a whole if there are some rules like
`replicate-wild-do-table=db1.%' or
`replicate-wild-ignore-table=db1.%', like it's already the case for
`CREATE DATABASE' and `DROP DATABASE' in replication. (Bug #1248)
* `mysqlbinlog' crashed (segmentation fault) when used with the `-h,
--host' option. (Bug #1258)
* `mysqlbinlog' crashed (segmentation fault) when used on binlog
containing only final events for `LOAD DATA'. (Bug #1340)
* Fixed compilation problem when compiling with OpenSSL 0.9.7 with
disabled old DES support (If `OPENSSL_DISABLE_OLD_DES_SUPPORT'
option was enabled).
* Slave no longer can delete temporary files for `LOAD DATA'
(`SQL_LOAD-*') belonging to other instances if these instances use
the same temporary directory. (Bug #1357)
* If `LOAD DATA INFILE' failed for a small file, the master forgot to
write a marker (a `Delete_file' event) in its binary log, so the
slave could not delete 2 files (`SQL_LOAD*.info' and
`SQL_LOAD*.data' from its `tmpdir'. (Bug #1391)
* On Windows, the slave forgot to delete a `SQL_LOAD*.info' file
from `tmpdir' after successfully replicating a `LOAD DATA INFILE'
command. (Bug #1392)
* When a connection terminates, MySQL writes `DROP TEMPORARY TABLE'
statements to the binary log for all temporary tables which the
connection had not explicitely dropped. MySQL forgot to backquote
the database and table names in the statement. (Bug #1345)
* On some 64-bit machines (some HP-UX and Solaris machines), a slave
installed with the 64-bit MySQL binary could not connect to its
master (it connected to itself instead). (Bug #1256, #1381)
* Code introduced in MySQL 4.0.15 for the slave to detect that the
master had died while writing a transaction to its binlog,
reported an error in a legal situation (when the slave I/O thread
was stopped while copying a transaction to the relay log, the
slave SQL thread would later pretend that it found an unfinished
transaction). (Bug #1475)
Additional notes:
* The Mac OS X binaries are now built on Mac OS X 10.2.6 with the
gcc-3.3 compiler.
* As HP-UX 10.20 has been discontinued by Hewlett-Packard on June 2002,
(http://www.hp.com/workstations/risc/standard/operating/hpux1020/discont.html),
we have now updated this build host to provide binaries HP-UX 11.00
instead.
* In addition to the IA32 Linux RPMs, we do now also offer RPMs for
Linux/AMD64 aka Opteron (built on SuSE Linux Enterprise Server 8)
