D.6.34. Alterações na distribuição 3.21.2

  • The range optimiser is coded, but only 85% tested. It can be enabled with --new, but it crashes core a lot yet...

  • More portable. Should compile on AIX and alpha-digital. At least the isam library should be relatively 64-bit clean.

  • New isamchk which can detect and fix more problems.

  • New options for isamlog.

  • Using new version of Automake.

  • Many small portability changes (from the AIX and alpha-digital port) Better checking of pthread(s) library.

  • czech error messages by .

  • Decreased size of some buffers to get fewer problems on systems with little memory. Also added more checks to handle ``out of memory'' problems.

  • mysqladmin: you can now do mysqladmin kill 5,6,7,8 to kill multiple threads.

  • When the maximum connection limit is reached, one extra connection by a user with the process_acl privilege is granted.

  • Added -O backlog=# option to mysqld.

  • Increased maximum packet size from 512K to 1024K for client.

  • Almost all of the function code is now tested in the internal test suite.

  • ALTER TABLE now returns warnings from field conversions.

  • Port changed to 3306 (got it reserved from ISI).

  • Added a fix for Visual FoxBase so that any schema name from a table specification is automatically removed.

  • New function ASCII().

  • Removed function BETWEEN(a,b,c). Use the standard SQL syntax instead: expr BETWEEN expr AND expr.

  • MySQL no longer has to use an extra temporary table when sorting on functions or SUM() functions.

  • Fixed bug that you couldn't use tbl_name.field_name in UPDATE.

  • Fixed SELECT DISTINCT when using 'hidden group'. For example: 

    mysql> SELECT DISTINCT MOD(some_field,10) FROM test
    ->        GROUP BY some_field;

    Note: some_field is normally in the SELECT part. Standard SQL should require it.
