[Maria-developers] 10.0 is now on github
by Sergei Golubchik 02 Mar '15

02 Mar '15

Hi, Olivier, Kentoku. Since when we've moved 10.1 development to git (about a year ago), the plan always was to move other trees to git too. So, last month we've moved all our development to git, 5.5 and 10.0 trees are now on github, in the https://github.com/MariaDB/server repository. I still keep launchpad trees, lp:maria/10.0, in particular, to be able to merge 10.0-connect, 10.0-spider, and 10.0-mroonga. When needed, I merge these trees to lp:maria/10.0, and then merge from lp:maria/10.0 to a 10.0 branch in the git repository. But it would be great if you could also move the development to git and github. The easiest and safest approach would be as follows: 1. you tell me when to do it. 2. I do the last merge of your lp tree to 10.0 and then to git and push it to github. 3. you fork https://github.com/MariaDB/server under your github account and then you can create your branch and do anything you want there. 4. tell me the url of your forked tree and I'll configure buildbot to build it. this way you don't need to export your changes from bzr to git (which takes few hours) - I'll do it (it'll be a couple of minutes for me, because I've already run git-remote-bzr many times, and it has all the data cached). And the history will be safer, as we can be sure that all already exported commits won't be re-exported the second time. So, just tell me when you're ready :) By the way, if you haven't pushed anything since 10.0.17 - that is, there's nothing to merge - you skip the first two steps and fork https://github.com/MariaDB/server right away. Good luck! Regards, Sergei

[Maria-developers] [MDEV-7586] Merged derived tables/VIEWs increment created_tmp_tables
by Vicențiu Ciorbaru 25 Feb '15

25 Feb '15

Hi Sergey! As discussed on the mdev page, I've implemented the fix for incrementing the created_tmp_tables variable. I've attached the patch for review. The changes in the patch are explained within the mdev page. commit 53d78644b793f7b667e71863ccd0b1ba54c894f3 Author: Vicențiu Ciorbaru <cvicentiu(a)gmail.com> Date: Sun Feb 22 03:40:17 2015 +0200 MDEV-7586: Merged derived tables/VIEWs increment created_tmp_tables Temporary table count fix. The number of temporary tables was increased when the table is not actually created. (when do_not_open was passed as TRUE to create_tmp_table). Another issue fixed is that create_tmp_table was called incorrectly in create_result_table, having keep_row_order passed for the do_not_open parameter and keep_row_order always set to false. diff --git a/mysql-test/r/tmp_table_count-7586.result b/mysql-test/r/tmp_table_count-7586.result new file mode 100644 index 0000000..0c526e0 --- /dev/null +++ b/mysql-test/r/tmp_table_count-7586.result @@ -0,0 +1,83 @@ +create table t2 (a int);

[Maria-developers] auth_socket/unix_socket auth plugin naming incompatibility with Percona Server
by John Leach 23 Feb '15

23 Feb '15

Hi, I just tested a switch from Percona Server 5.6 to MariaDB 10.0.16 and hit a problem with socket authentication. I had it set up to auth root using the auth_socket plugin, but when I switched to MariaDB I could no longer login as root. I get this error from the client: ERROR 1524 (HY000): Plugin 'auth_socket' is not loaded Anyway, after I bunch of investigation, I found that the plugin used to expose itself as socket_peercred but was renamed due to a conflict and Percona and MariaDB chose different names to fix it. Percona renamed it to auth_socket, matching the actual library filename auth_socket.so and MariaDB chose unix_socket, but keeping the filename auth_socket.so: https://github.com/MariaDB/server/commit/b8b7b4eb6bef26d05257272be02674ae55… https://github.com/percona/percona-server/commit/91a2afcbcba8af28d2f10f8083… This isn't great, but it's made worse because the plugin is successfully loaded in both cases (because the filename is auth_socket.so) and no errors are reported in the logs, but the plugin just exposes itself internally using a different name so reports that auth_socket isn't loaded in MariaDB. I fixed it by starting mysql with skip-grant-tables and running: update mysql.user set plugin='unix_socket' where plugin='auth_socket'; but that alone doesn't work, because MariaDB doesn't know that unix_socket is provided by auth_socket.so: ERROR 1524 (HY000): Plugin 'unix_socket' is not loaded So I then added this to the config file, which fixed it: plugin-load=unix_socket=auth_socket.so Any thoughts on what to do here? Can the plugin be made to recognise both names, so other users don't end up in this situation? I presume there would need to be both auth_socket.so and unix_socket.so. I also presume Percona would need to provide the same, to help those moving from MariaDB to Percona. Thanks, John. -- https://www.brightbox.com
