[Maria-developers] Difference between 0xHHHH and X'HHHH' hex literals
by Alexander Barkov 24 Apr '14

24 Apr '14

Hello Ian, I tried to explain in https://mariadb.atlassian.net/browse/MDEV-6092 to the complainer why it's not a bug. Can you please document the difference between the two hex notations and then close as "not a bug"? Thanks.

I noticed an error in a build though: https://buildbot.askmonty.org/buildbot/builders/kvm-tarbake-jaunty-x86/buil… The "kernel" log has this: ----------------------------------------------------------------------- /dev/sda1 contains a file system with errors, check forced. /dev/sda1: Entry 'pack-names' in /home/buildbot/.bzr/repository (3415) has an incorrect filetype (was 1, should be 2). /dev/sda1: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. (i.e., without -a or -p options) ----------------------------------------------------------------------- One likely reason is a failed rsync step. This is the tarbake build; unlike most other virtual machines, this one is actually modified during a build. So it's quite possible that the rsync would go wrong if a tarbake build happened to run in the meantime. So just re-sync that particular VM, and that might solve the problem. Thanks for setting this up! - Kristian.

[Maria-developers] [GSoC] Accepted student ready to work : )
by Pablo Estrada 23 Apr '14

23 Apr '14

Hello Sergei, Elena and everyone, I'm Pablo, and I was selected as part of Google Summer of Code 2014 to work on the project "*Statistically optimize mysql-test runs by running less tests*". First of all, thank you very much for having selected me for the project. I am very excited to start reading, reviewing data and coding up. I see that Elena will be my mentor. Nice to meet you Elena : ) To begin with, I am focusing on the *Buildbot documentation*, to *(1)understand how the data is organized* inside it, and to *(2)*figure out *how to add the extra functionality* into the BuildBot. I want to get started with the data analysis, so it would be great if you could help me with the following things: 1. Sergei, you said you did a bit of research into this. Do you have your *previous results*, or *any papers* that you have read that you could suggest to me? 2. Can I get *access to the buildbot database* to look at the data? If not, can I get the E/R model, or any scheme of *how the data looks like?* - I understand that maybe the data is not just a single database. I am starting by *reading the buildbot documentation*, to understand how the stuff is organized in it. 3. *Any other information* that you consider useful for me to know? Any advice? And that's all I have for now. I'm looking forward to getting started! Regards Pablo

Hi Sergei, Alexander and all, Thank you for accepting my proposal. This was the first time I applied for GSoC, so I was kind of nervous. I was selected to work on the project *"CREATE OR REPLACE, CREATE IF NOT EXISTS and DROP IF EXISTS" *as part of GSoC'14. My end semester exams are going on right now. I will be done with my exams and projects by 29th April. I am totally excited to get started. I have built the source code already. Have learnt a few things about the source code as you must have observed in my proposal. I will continue with the documentation and source code from 1st May. Is there anything else you want me to look into? Thanks, Sriram

[Maria-developers] TokuDB disabled in Debian and Ubuntu - help me get it working?
by Otto Kekäläinen 18 Apr '14

18 Apr '14

Hello Rick, Last year I spent a lot of time packaging MariaDB 5.5 for Debian and finally this year it has landed in Ubuntu 14.04 and Debian testing. Unfortunately the Debian/Ubuntu version does not include TokuDB and I need your help to get it there. In 5.5.35 (I think) the TokuDB plugn was added to MariaDB but I had issues getting it build 100% correctly and I eventually dropped it (added build parameter -DWITHOUT_TOKUDB=true), as getting MariaDB in Debian at all was a bigger priority than getting it there with every possible plugin. The root cause seems to be that when Debian and Ubuntu packages are built in chroot environments (the build systems of Debian and Ubuntu use pbuilder/sbuilder systems, see https://en.wikipedia.org/wiki/Debian_build_toolchain#Isolated_build_environ…) the code that builds the plugin does not seem to correctly detect the CPU features. It seems to read the values from the build machine and not the inputted target values (in a cross-compile situation). There are two related issues that needs a solution: 1) Currenlty the code that checks what the architecture is (32-bit/64-bit) is the first lines of https://bazaar.launchpad.net/~maria-captains/maria/10.0/view/head:/storage/…. This works well for real and virtual machhines, but it does not seem to work in the pbuilder/sbuilder chroots, as CMAKE_SYSTEM_PROCESSOR always shows the chroot host CPU, not the cross-compile target CPU. Could you please investigate pbuilder/sbuilder and search for some solution that works for reliable target CPU checking? 2) When building TokuDB in Ubuntu (amd64) sbuilder environments something in crashes in the 'toku_os_get_processor_frequency' function. For this too, could you investigate the sbuilde chroot environment and figure out what goes on and how to fix it? Issue 2 has a bug report with the (a bit messy) debugging history documented: https://mariadb.atlassian.net/browse/MDEV-5618 Both of these issues requires learning a bit about sbuilder CPU things, so I assume it is most efficient if the same persons looks into both of these.

[Maria-developers] Ubuntu 14.04 and MariaDB
by Otto Kekäläinen 17 Apr '14

17 Apr '14

Ubuntu 14.04 was released today. >From https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes#Ubuntu_Server "MySQL Ubuntu 14.04 LTS continues to provide official support for MySQL 5.5. Three other community supported alternatives of MySQL are also included: * MariaDB 5.5 - a drop in replacement for MySQL 5.5. * Percona XtraDB Cluster 5.5 - a Galera based Active/Active MySQL solution. * MySQL 5.6 - the next release of Oracle's MySQL. Note that upgrading to MySQL 5.6 is an automatic one way process; it is possible to downgrade manually - see the upstream documentation on details of how to perform this process." I have been working on 5.5.37 today, I hope to soon get it uploaded into Debian and then via security update process into Ubuntu too. -- Check out our blog at http://seravo.fi/blog and follow @ottokekalainen

Please mention what tools/languages you think you'll be using. > Also, if I could see the data available (the history of test results), I > could write more in detail : ) Hm. Okay. Attached is the preprocessed table that I used two years ago. It lists test failures in buildbot in a given period of time. Columns are (as far as I remember): * time of the test run start * code branch that was tested * revision id that was tested - it's fake, our buildbot tables don't store revision id. I've constructed it from the set of changed files, revision number, etc. hopefully it's as unique as a real revision id * build number * platform where the tests were run * test type - basically, the set of tests to run and what protocol to use. one test may be run with different protocols * test name * test variant - or combination. certain tests may be run in many combinations Using tis file I tried to rearrange test execution order for every specific build number (using failure data from previous builds in the same table) to detect test failures as early as possible. I managed to have 90% of all test failures happening within first 10% of the tests. The goal of this project is to have something we can put back into buildbot, so that it could actually run only 10% of the tests, still having 90% probability of discovering a failure (or 20%, or 95%, whaveter). See also http://buildbot.askmonty.org/buildbot/ you can click on a link for any branch, for example, http://buildbot.askmonty.org/buildbot/grid?branch=10.0 then on any particular build, for example, http://buildbot.askmonty.org/buildbot/builders/kvm-fulltest/builds/2297 and on a stdio log for a particular test run: http://buildbot.askmonty.org/buildbot/builders/kvm-fulltest/builds/2297/ste… on these pages you'll see what a platform (builder) is, build number, test types, combinations, etc. Regards, Sergei

[Maria-developers] MariaDB release and support policies

Hello! Does MariaDB promise a 8 year release cycle for 5.5 as MySQL does? Does all of the points listed at https://lists.ubuntu.com/archives/technical-board/2014-February/001812.html apply for MariaDB as well? Can we promise Ubuntu that all MariaDB minor releases fulfill the quality requirements listed above? If so, I'll then file a micro release update permission request for Ubuntu. AFAIK as I know it is the only way to get security releases to users anyway. PS.

It sounds like what you want is some option on the slave that would cause it to ignore all GTIDs with some specific domain id, similar to how it is currently possible to filter on server id. That seems a reasonable request; such option does not exist currently though. Another option is to use the @@skip_replication variable. Set this for the sessions doing the "local" transactions. Then set replicate_events_marked_for_skip to either FILTER_ON_SLAVE or FILTER_ON_MASTER, as you like. This is specifically designed to allow to log certain transactions to the binlog but not replicate them, so it sounds like it is what you asked for. > 2) There will be some challenge in maintaining the sequence number for GTID > correctly: for global GTID purposes, we can just count commits, and skip every > local transaction commit, but, we must also initialize the sequence for every > node joining the cluster. In MySQL-5.6 this happens by copying binlog files > (only header part needed) to joining node. I wonder if same strategy works for > MGC-10, is MariaDB GTID is stored in binlog header ? Yes, the GTID is stored in the binlog header. It is also stored in a file master-bin.state. This file is read at server start to initialise the GTID sequence numbers. However, if the file is not found for any reason, the information is extracted from the last binlog file (the master-bin.state is just a cache). However, you need the whole binlog file (if master-bin.state is missing), not just the header. I am sure it must be the same for MySQL-5.6 - you need to scan to the end of the binlog file, as there may be extra GTIDs logged in the file that were not there when the header was written. Of course, just after server start, the most recent binlog file is empty, so just the header works. It sounds like you would want to just copy over the master-bin.state file. However, this whole approach sounds wrong to me. The current GTID state is a cluster-wide property, not a local property, I do not understand why you want to maintain it locally. As I understand it, Galera decides on commit order. The certification process decides for parallel transactions T1 and T2 which one will be committed before the other. The GTID sequence has to match the commit order. So the GTIDs need to be generated by Galera, at the point in the code where the commit order is decided. This Galera code then also needs to do the binlog writing, so that binlog order matches GTID order and commit order. With Galera handling GTID number allocations, I do not understand why you would need to worry about binlog headers. But maybe I have misunderstood, I do not know Galera in details. Maybe you could explain how Galera ensures matching commit order, binlog order, and GTID order? Or alternatively, explain how things work without such ensurance? > 3) Independent table (in data dictionary) or file for replication filters.

Currently we do not have this, replication filters are configuration options, and those are stored in the config file, not in dynamic tables or files. The server_id filters are set by CHANGE MASTER though, IIRC, so they are stored in master.info / relay_log.info. > 4) Dynamic binlog. Currently options are read-only. This we do not have. There has been talk of allowing it under global read lock; this might work, but it would require some work to carefully check all of the code for possible issues. There are a lot of places in the code where expensive synchronisation/locking is avoided based on the knowledge that the binlog can not be enabled or disabled on-the-fly. Hope this helps, - Kristian.

[Maria-developers] debugging MDEV-5932, wrong result set for tokudb
by Rich Prohaska 10 Apr '14

10 Apr '14

Hello, TokuDB generates an empty result set for a select with sub-select, but generated a non-empty result set for the same query when creating a new table. The result set should be the same in both cases. What is going on here? InnoDB computes an empty result set for both cases. I traced the problem to the tokudb::index_read function. The tokudb::index_read does not handle the null byte key prefix. Unfortunately, I do not understand how the null byte (byte 0) in the key handed to the ::index_read function is supposed to work. Most of the time, the value of this byte is 0. Sometimes it is set to 1. How should the storage engine work WRT this? BTW, this problem exists with TokuDB in MySQL 5.5.36, MySQL 5.6.16. I have not been able to consistently see this on MariaDB 5.5.36 for some reason. In any case, I am interested in how the handler's index_read function is supposed to process the null byte. Thanks

[Maria-developers] Buildbot machines
by Rasmus Johansson 09 Apr '14

09 Apr '14

Hi, I discussed both with Dbart and Serg last week about the situation with buildbot. Kristian and Elena also had similar discussion on IRC today. To sum it up, there seems to be two aspects to it; 1) more machines, i.e. slaves could/should be added immediately and 2) some development work could/should be done on buildbot to support some other ways of building, like automatically spinning up and down platform specific virtual machines in a public cloud somewhere whenever they are needed. I looked into alternatives for the 1) immediate need of more machines and thought. I found a pretty interesting alternative from OVH.COM, who offers dedicated servers to a very reasonable price. Here is a good example of what they can offer: https://www.ovh.com/us/dedicated-servers/infra/2014-EG-32.xml . I would be prepared to give it a try. Do you think the specs are good enough to help with the load buildbot currently has? BR, Rasmus -- Rasmus Johansson, VP Engineering MariaDB | t: +358 50 499 9589 | Skype: ratzpo

That's up to you. Sometimes I create functions with the same name, sometimes I don't. For example, tdc_acquire_share() - there are few functions with the same name, because they do exactly the same. Actually, one of tdc_acquire_share() is a real function, others are inline convenience wrappers - they eventually call the "real" one. But tdc_acquire_share_shortlived() - while also only a convenience wrapper - has a different name to emphasize that it has different semantics. But anyway, that's your patch. If you'd like to rename - go ahead. Regards, Sergei

[Maria-developers] Vision for next 10.x minor releases
by Honza Horak 08 Apr '14

08 Apr '14

Hi guys, first, congratulations for the 10.0 release, well done! Even though it can look insane, I'm already wondering about next minor releases ;) Especially if you have already some idea about 10.1 and later. Specifically, I'm wondering if these releases will still be somehow tight to MySQL's release cycle (say 10.1 will be somehow following 5.7) or if you plan totally independent release schedule like slower/faster the release cadence? In other words, since MySQL changed only minor version and MariaDB bumped the major (we all know the reason), I'm wondering if something changed in thinking about major/minor versioning -- like if the difference between 10.0 and 10.1 will still be considered the same like between say 5.3 and 5.5. I don't expect you can give us any dates, but some expectations, if 10.1 can be expected in months or rather years? If that was already discussed somewhere, please, just point me to the correct place. Thanks, Honza
