FTR, we would not *drop* MySQL support. Worst case scenario, we'd place them in partner, much like we did with sun-java.

One thing to note, the primary motivator for this proposal isn't about moving to a more "open source friendly" application. We have genuine security concerns/issues with how MySQL handles and publishes their security updates. We can't simply update supported prior Ubuntu releases to newer MySQL versions, so we have to backport patches. Their lack of information and access to the bugs addressed makes it *very* time consuming and difficult for our security and SRU teams to do this. If we can resolve these issues, then MySQL's future in main looks much brighter. -Robbie -- Robbie Williamson <robbie(a)ubuntu.com> robbiew[irc.freenode.net] "Don't make me angry...you wouldn't like me when I'm angry." -Bruce Banner

[Maria-discuss] New KB Question: millisecond part is trimmed away when saving Java Date obj by hibernate
by Daniel Bartholomew 14 Feb '12

14 Feb '12

A new question has been posted in the Knowledgebase: http://kb.askmonty.org/en/millisecond-part-is-trimmed-away-when-saving-java… ---------------------------------------- Hi, I recently upgraded my MySQL DB to MariaDB for millisecond support. I can see the millisecond part in my upgraded database. And I tested the millisecond support by inserting a row to a table of my db. It functions well. But when I use hibernate to save a java.util.Date obj into database, millisecond part is trimmed and in MariaDB date obj is saved as: 2012-02-13 18:40:55.000. Do I need to set up something to activate millisecond support? Or I need to config hibernate for millisecond support? Thanks a lot! ---------------------------------------- Thanks. -- Daniel Bartholomew MariaDB - http://mariadb.org Monty Program - http://montyprogram.com AskMonty Knowledgebase - http://kb.askmonty.org

I predict it will be the opposite. Once distros and people start switching to MariaDB, other projects will be testing on MariaDB by default, and compatibility with MySQL will then become problematic.

Hi everyone, I'm mariadb's port maintainer for FreeBSD, and I'd like to get it compile before pushing the 5.2.10 update... Seems to be the same problem than under OSX: (with openpam) https://lists.launchpad.net/maria-discuss/msg00506.html Under FreeBSD 9.0RC3 (and 8.2) amd64: libtool: compile: cc -DHAVE_CONFIG_H -I. -I. -I../../include -I../../include -I/usr/local/include -DMYSQL_DYNAMIC_PLUGIN -O2 -pipe -fno-strict-aliasing -MT auth_pam_la-auth_pam.lo -MD -MP -MF .deps/auth_pam_la-auth_pam.Tpo -c auth_pam.c -fPIC -DPIC -o .libs/auth_pam_la-auth_pam.o auth_pam.c:107: error: 'pam_info' redeclared as different kind of symbol /usr/include/security/openpam.h:102: error: previous declaration of 'pam_info' was here *** Error code 1 1 error *** Error code 1 1 error *** Error code 1 1 error *** Error code 1 Sergei Golubchik wrote 'Fixed' in the referenced mail, but I don't know if it's fixed by removing pam support for OSX or ? (did not find any difference in bzr branch 5.2) Should I disable pam support for FreeBSD or is there any patch I could include in the port for 5.2.10 ?

[Maria-discuss] MariaDB 5.3.3-rc now available
by Daniel Bartholomew 21 Dec '11

21 Dec '11

The MariaDB project would like to announce the availability of MariaDB 5.3.3-rc, the latest addition to our growing lineup of supported software. MariaDB 5.3.3-rc is the first Release Candidate release in the 5.3 series. We hope to follow it up soon with a stable (GA) 5.3 release. == MariaDB 5.3.3-rc Release Notes, Changelog, Downloads =============== The release notes for MariaDB 5.3.3-rc are available from: http://kb.askmonty.org/en/mariadb-533-release-notes A complete changelog for this beta is available from: http://kb.askmonty.org/en/mariadb-533-changelog Sources, binaries and packages can be downloaded from: http://downloads.askmonty.org/mariadb/5.3.3/ Debian and Ubuntu packages (now including Ubuntu 11.10 "Oneiric") are available from our mirrored apt repositories. A sources.list generator can be found at: http://downloads.askmonty.org/mariadb/repositories/ == About MariaDB 5.3.3-rc ============================================= In MariaDB 5.3.3-rc there are a couple of changes compared to previous 5.3 releases: === Performance: Several optimizer features introduced in MariaDB 5.3 have been thoroughly tested, and switched on by default in 5.3.3. These include: * Subquery materialization (materialization=on) http://kb.askmonty.org/en/non-semi-join-subquery-optimizations * Semi-join optimizations (semijoin=on,firstmatch=on,loosescan=on) http://kb.askmonty.org/en/semi-join-subquery-optimizations * Derived table optimization (derived_merge=on,derived_with_keys=on) (Documentation is being worked on) * Index Condition Pushdown (index_condition_pushdown=on) http://kb.askmonty.org/en/index-condition-pushdown * Nested loop join will use its Block-based variant more aggressively http://kb.askmonty.org/en/block-based-join-algorithms * Block-based join for OUTER JOINs (outer_join_with_cache=on) * Block-based join for semi-joins (semijoin_with_cache=on) * Linked join buffers (more aggressive buffering of multi-way joins) (@@join_cache_level==2) Also, DISTINCT and GROUP BY clauses are now removed from subqueries when possible. This allows for more efficient query plans. (backported from MySQL 5.6) === Usability: EXPLAIN output has been improved in MariaDB 5.3.3 to be easier to understand: * The select_type column now shows MATERIALIZED for subqueries that are executed with Materialization (it used to show SUBQUERY, which made it hard to distinguish materialized subqueries from other kinds subqueries). * For a Duplicate Elimination strategy, Start temporary is now shown at the first table from the subquery. See also: http://kb.askmonty.org/en/explain === GIS Operations: GIS precise operations were added in MariaDB 5.3.3 (Documentation for this is still being worked on). == About MariaDB 5.3 ================================================== The MariaDB 5.3 series introduces many new features, includes MariaDB 5.2, and is based on MariaDB 5.1 & MySQL 5.1. Some highlights of new features in MariaDB 5.3 include: - subquery optimizations that finally make subqueries usable - many optimizer changes, including Classic Hash Join, Batched Key Access, a new implementation of Multi-Range-Read optimizations as well as Index Condition Pushdown - NoSQL-style interfaces via the HandlerSocket plugin as well as dynamic columns - group commit in XtraDB when the binary log is enabled - Microsoft Windows performance improvements These are just some of the highlights, and for a more complete list of changes, please read the What is MariaDB 5.3 page: http://kb.askmonty.org/en/what-is-mariadb-53 == User Feedback plugin =============================================== MariaDB 5.3 includes a User Feedback plugin. This plugin is disabled by default. If enabled, it submits anonymous basic MariaDB usage information. This information will be used by the developers to track trends in MariaDB usage to better guide development efforts. If you would like to help make MariaDB better, please add --plugin-load=feedback.so to your my.cnf file! On Windows, add "feedback=ON" to your my.ini file, or click the checkbox during the installation of the MSI package.
