TODO come up with a list of options to set. 1.4 Items not on the wishlist ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This is a list of things that one might want an installer to do but that are out of scope of this WL entry: * Calibration of my.cnf parameters based on available memory, number of CPUs, etc. 2. Installer wishlist (developer POV) ------------------------------------- * Some "installshield-like" tool that's easy to use (suggestion by Webyog: NSIS) * Installation procedure source should reside in MariaDB source repository * Installation procedure source file is better to be in human-readable text format. * It should be possible to automate creation of the installer package, in a way that can be run from buildbot (e.g. the installer package build process should print messages to its stdout) * Any suggestions on how can one automatically test the installation package? (for example, we'll want to start the installer, install, check that installation succeeded, then start the server, run some commands, then uninstall. Any ways to achieve that?) 3. Other notes -------------- * MariaDB's logo is the seal. It can be found here: http://askmonty.org/wiki/index.php/MariaDB_Logo * We should make both 32-bit installer and 64-bit installer (the latter will be possible when we have 64-bit windows binaries) * At this point we don't see a need to force a reboot after the installation. * The installer should be Vista and Windows7-proof.

(TODO: should the uninstaller the datadir or leave it? (or ask the user?)) - Creates installation log, and in case of any failures presents the log to the user and requests to file it as a bug (How far we should go here depends on how complex and error-prone the final installation procedure will be). 1.2 Step 2: Upgrades from MySQL or MariaDB ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Same as above but with handling of the case where MySQL has been already installed: - offer to replace MySQL. - upgrade the data directory (todo we should sort out if anything/what is needed for this). - Uninstall MySQL - Install MariaDB. 1.3 Step 3: Configuration wizard ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - Installer should include configuration wizard that's similar to what MySQL installer does. TODO come up with a list of options to set. 1.4 Items not on the wishlist ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This is a list of things that one might want an installer to do but that are out of scope of this WL entry: * Calibration of my.cnf parameters based on available memory, number of CPUs, etc. 2. Installer wishlist (developer POV) ------------------------------------- * Some "installshield-like" tool that's easy to use (suggestion by Webyog: NSIS) * Installation procedure source should reside in MariaDB source repository * Installation procedure source file is better to be in human-readable text format. * It should be possible to automate creation of the installer package, in a way that can be run from buildbot (e.g. the installer package build process should print messages to its stdout) * Any suggestions on how can one automatically test the installation package? (for example, we'll want to start the installer, install, check that installation succeeded, then start the server, run some commands, then uninstall. Any ways to achieve that?) 3. Other notes -------------- * MariaDB's logo is the seal. It can be found here: http://askmonty.org/wiki/index.php/MariaDB_Logo * We should make both 32-bit installer and 64-bit installer (the latter will be possible when we have 64-bit windows binaries) * At this point we don't see a need to force a reboot after the installation. * The installer should be Vista and Windows7-proof.

[Maria-developers] Summary of discussion about MariaDB future and release plans
by Kristian Nielsen 13 May '10

13 May '10

Hi, With all the european MariaDB people stuck in California, there is an unexpected opportunity for extra face-to-face meetups. So today I had the opportunity to enjoy lunch at a nice sushi place in Santa Clara with Henrik, Timour, Peter, Vadim, and Sanja. Here are a couple of key points from the discussion: 1. We need to consider carefully how we handle keeping the MariaDB product stable for production use. Peter had the point that the critical thing is avoiding behaviour change. This means that if some version of MariaDB works sufficiently different that the user need to work on their application to upgrade, it is a blocker to adoption. Different in this context means different from any previous version of MariaDB, but it _also_ means any difference from MySQL! I think I can see that this is actually more important than mere bugs/regressions. If a bug slips through, we can fix it, and if we can fix it quick enough the user may even be happy with us. But if the behaviour is qualitatively different (and such difference can not easily be turned off), that is a real problem for the user. We discussed a lot around this for the subquery optimisations. This is a "scary feature", as it has the very real potential to change execution plans, occasionally for the worse. As Timour pointed out, there is for each new optimiser feature a server variable to enable/disable it. So we need to very clearly state in the release notes, under "upgrading to MariaDB x.y", that there are optimiser changes, and give the exact list of variable settings that will make the optimiser run in "MySQL 5.1 mode". For other features this is simpler. For storage engines, just disable the engine and it will have no impact. For possibly replication plugins, again don't use the plugin and there should be no difference in behaviour. But again, we need to very carefully think about this and communicate/document this. For other features again we might need to re-think this point, making sure we do not change behaviour in a non reversible way. I think this is a good observation from those with a deep knowledge of the operational side of Databases. 2. On a note related to stability, I think we need to carefully avoid the mistakes from the MySQL release model. Basically, we need to have regular releases (6-12 month cycles). This is all-important! Much more important than any single feature, however big. We must _never_ push a feature into a tree if it is not ready. Better make an empty release! So this means it is actually wrong to say that subqueries will be in MariaDB 5.3. That should not be the plan. The subqueries will be in the first release made after they are ready. Which maybe 5.3, may be something else. I think we very nearly made the same mistake with 5.2. We had a feature list, and while some of them were "rolling", we also had features that were decided in advance that they _must_ be pushed at a certain date. I strongly believe this is wrong. We should have made _all_ features rolling. Unless we are extremely careful with this, sooner or later there will be sufficient pressure that we will push unfinished stuff into a release, causing _all_ of that release to be a failure. By waiting with the unfinished feature, only that feature will "fail", and by being careful with releases, the next release will be close anyway. (Yes, "finished" cannot mean bug free. But it can mean "as good as we can reasonably make it".) 3. The final point I took from the discussion was related to version numbering. We in the MariaDB team of course know that we rock, and that we will change the world tomorrow, or at least as soon as planes will take us back to Europe :-). But the reality is that for now, we are an appendix to MySQL with MariaDB 5.1 and 5.2. It thus can be argued that this should be reflected in the version numbering, to avoid confusion. Peter made the point that he would like to see MariaDB 5.1 and 5.2 versioning be made so that it is clear that there is a base MySQL version plus some well-defined set of changes. (This is how XtraDB release numbering works). So we currently have MariaDB 5.1.44, which is equivalent to MySQL 5.1.44 plus some set of safe patches. But MariaDB 5.2.0 is actually the same, just with some additional, also safe patches. So rather than go to MariaDB 5.2, we could imagine something like this: MariaDB 5.1.44-1 Current MariaDB 5.1.44 MariaDB 5.1.44-2 Current MariaDB 5.2.0 MariaDB 5.1.44-1.1 In case we need to do a bugfix for 5.1.44-1 MariaDB 5.1.46-1 Next time we merge MySQL 5.1.46 into MariaDB -1 MariaDB 5.1.46-2 Next time we merge MySQL 5.1.46 into MariaDB -2 I need to think more before I fully make up my mind about these points one way or the other, but I think these are in any case interesting points to consider. - Kristian.
