Re: [Maria-developers] Windows installer kick-off

Hi All, one thing we need to know is that windows users a lot of the times are beginners. In addition to that the installer needs to be able to: 1. create the default user 2. Choose the location of the data files (not just innoDB but for the other storage engines) 3. Ability to install multiple servers based on port 4. Tell the user to reboot the computer after installation. I found sometimes after a fresh install of mysql on windows it doesnt say that but the server behaves erratic until the time one has to restart the computer.

A newcomer does not know enough to either sensibly decide on storage engine, or sql_mode. So we should pick what is sensible, and that's InnoDB with sql_mode=TRADITIONAL. As I noted, this is already what the Sun/MySQL Windows wizard defaults to, unless you specify that you don't want transactions. Now the latter is something I don't care for asking, because people really don't appreciate the implications of the question. Furthermore, it would be great to have MariaDB be ACID compliant "out of the box", on all platforms. And it'd be nice if the config on Windows would be (at least broadly) the same as on *nix. > I don't think it makes sense to offer the user to specify options like > query_cache_size - there's hardly anybody who could come up with a > meaningful > value at install time.

for developing the *SERVER *(in the wide sense), XP is fine. But the * INSTALLER* will have to take UAC and PCA into account. That requires testing on Vista, 2008 or Win7.

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.

HIGH-LEVEL SPECIFICATION: Not a spec so far but a list of points to consider: 1. Installer wishlist (user POV) -------------------------------- >From the user point of view: 1.1 Step 1: simple installer ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ An installer package that - Presents the user with GPL licence - Prompts the user for "essential" configuration options: * Install directory - Data directory (see email from Peter Laursen on maria-developers@ dated 14-10-2009 about data directory, Vista and UAC) * root password * default character set * [possibly] sql_mode setting. - Checks if the target installation directory, TCP port, or named pipe are busy. If they are, offers to either change these parameters or abort the installation (that is: no support for any kind of upgrades at this point) - Copies installation files to appropriate destination - Registers mysqld a service - Generates appropriate my.cnf file - Sets up SQL root user with the specified password - Adds start menu items - to start the server manually (with --console) (note: starting server manually requires write access to datadir, which not all users will have. what to do?) - to start mysql client - to edit the my.cnf file. - Registers MariaDB to start as a service with the specified parameters. - Registers MariaDB as installed software, sets up uninstaller. (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] Merging MySQL 5.1.39 into MariaDB
by Kristian Nielsen 16 Oct '09

16 Oct '09

I have completed a merge of MySQL 5.1.39 into MariaDB. The merge is pushed into lp:~maria-captains/maria/mariadb-5.1-knielsen for testing. Note that pushing the merge into main is currently blocked by a regression introduced in MySQL 5.1.39 by the patch for Bug#45261. I mailed the MySQL developers about this: http://lists.mysql.com/internals/37377 Due to this regression, the new TIME_MS column in INFORMATION_SCHEMA.PROCESSLIST in MariaDB is broken, as seen in test failures like main.create. Hopefully the MySQL developers can help on how to resolve this. The issue is a bit complex, concerning truncation issues with DECIMAL types. - Kristian.
