Hi guys, i found a bug at query cache and sent a patch to solve it https://mariadb.atlassian.net/browse/MDEV-6781 https://github.com/rspadim/server/commit/5a5e47bf4141ebc3584ed365173dde87b7… there's a pull request at 10.1 github (that's only a line removing a +1 at database name length) please review the patch that was only found cause i'm using qc_info plugin from mdev-4682 thanks :) -- Roberto Spadim

[Maria-developers] OQGRAPH/others engine and query cache
by Roberto Spadim 24 Sep '14

24 Sep '14

Hi guys i was checking OQGRAPH limitations with query cache it can't use query cache cause we don't know when data base change, that's ok right? i think that's ok too some others engines have this 'problem' too the first answer is, since oqgraph can't know when data table changes, we can't cache oqgraph tables... i think that's right BUT... query cache 'save' table used in query cache, for example: select * from oq_graph this will include "select * from oq_graph" at query cache using table 'oq_graph' instead of only using 'oq_graph' we could include 'oq_graph' AND 'data_table' even when we 'only' use oq_graph at FROM part this is more interesting than turning query cache off to oq_graph, and this remove the problem of "the data table don't tell oqgraph when we need to invalidate query cache" and that's right! but since data_table changed it will invalidate all queries using it, including oq_graph queries =) check if i'm not wrong, i can try a patch with it if we don't have others query cache related problems (for example query cache don't support tables outside query) -- Roberto Spadim SPAEmpresarial Eng.

[Maria-developers] More upgrades needed for work-amd64-valgrind
by Sergey Petrunia 24 Sep '14

24 Sep '14

Hello Jani, Thanks for getting git to work for work-amd64-valgrind host. I am looking at http://buildbot.askmonty.org/buildbot/grid?branch=10.1 and see that "git update" step succeeds. However, the next step fails: http://buildbot.askmonty.org/buildbot/builders/work-amd64-valgrind/builds/6… it is probably because of cmake being too old. Could you please update cmake on work-amd64-valgrind, also? BR Sergei -- Sergei Petrunia, Software Developer MariaDB | Skype: sergefp | Blog: http://s.petrunia.net/blog

Re: [Maria-developers] [Maria-discuss] MariaDB encryption
by Jonas Oreland 23 Sep '14

Hi again, > What is the type of license of your code? I asked internally about license, and it seems like we releasing dual gpl2/apache licensed code. > I would like to know, which interfaces from maria-DB you are using. I don't 100% understand the question. We didn't write any actual encryption code, but used the one provided in openssl. Other than that, we didn't really "use interfaces", but rather added/modified functionality/interfaces here and there.

[Maria-developers] Switching on use of components in Jira
by Rasmus Johansson 23 Sep '14

23 Sep '14

Hello all, I will later today switch on the usage of Components in Jira. Components are a way of grouping issues inside a project. The idea is to map every issue in Jira, being it a bug or a new feature to a component which describes to what area of MariaDB the issue belongs. For example a bug in Aria would be marked with the component "Storage Engine - Aria". Currently there are 37 components defined in Jira that should cover many areas, but I'm sure there are a few missing. There is one generic to which you can assign issues that doesn't fall into any other category, called OTHER. I'll include the list of components here in the end of this email. * What do you need to do? * The Component field will be a mandatory field when closing an issue. Therefore if a component (or several components) haven't been specified earlier for an issue, you'll have to choose at least one when closing an issue. The field has autocompletion so if you start typing for example "Galera" you'll be presented with the alternatives "Galera", "Galera Arbitrator garbd", and "Galera SST". If you don't find a suitable component then choose the component called "OTHER". * What is the benefit of using components? * It's a way of organizing issues inside a project, so that you easily can pull out all issues related to a certain area of MariaDB, e.g. if I wanted to know all bug fixes for replication I would click on the Replication component and get a list. There is the possibility to set up automatic assignees based on components and components can be used in filters and reports throughout Jira. I hope this won't be a burden. All feedback is of course welcome. BR, Rasmus * Components in the MariaDB Server project in JIRA * Data Definition - Alter Table Data Definition - Procedure Data Definition - Temporary Data Manipulation - Insert Delayed Data Manipulation - Subquery Dynamic Columns Events Full-text Search Galera Galera Arbitrator garbd Galera SST GIS Locale Settings OTHER Platform Debian Platform FreeBSD Platform Power Platform Windows Plugin - Audit Plugins Query Cache Replication Show Profile sql_error_log SSL Storage Engine - Aria Storage Engine - Cassandra Storage Engine - Connect Storage Engine - InnoDB Storage Engine - OQGRAPH Storage Engine - Spider Storage Engine - XtraDB Storage Enging - TokuDB Time zones Triggers Views XML Functions

[Maria-developers] Close some MDEV
by Roberto Spadim 22 Sep '14

22 Sep '14

Hi guys, could close these mdev: 1)MDEV-4599 (it will be implemented at mdev-4584) 2)MDEV-4581 (it will be implemented at mdev-4682) Please check this mdev-4682 too, i sent a patch via github, there's an option that should be implemented at compile time to turn stats on/off i didn't checked how to implement it yet, if anyone could help me :) it must set a macro #define QUERY_CACHE_QC_INFO_PLUGIN 1 at "configure" time, maybe via cmake gui or something like it maybe i should change QUERY_CACHE_QC_INFO_PLUGIN to QUERY_CACHE_INCLUDE_STATS to easier understand of macro definitions, help is wellcome here -- Roberto Spadim
