** Moved the responsibility for calling setupSchemaVars() on install to the DatabaseInstaller subclass. This allows it to be called after setupDatabase() has completed, as required by Oracle and PostgreSQL.
** Fixed OracleInstaller::getConnection() so that it respects $this->useSysDBA correctly.
** In OracleInstaller, added some more variables to the list of schema vars, which are needed by user.sql and tables.sql
** In SearchOracle, specify the database name when calling ctx_ddl.sync_index(). This fixes a fatal error in the createMainpage step, caused by the schema name not being equal to the current user.
* In oracle/tables.sql, fixed a couple of indexes with missing table prefixes.
* Improved debugging output in DatabaseInstaller::getConnection() and Installer::createMainpage().
* In DatabaseBase::selectDB(), set $this->mDBname correctly, as in DatabaseMysql.
* Fixed a bug causing the engine and charset settings to not be properly preserved when adding new tables on upgrade.
* Fixed total breakage of SQLite upgrade, by reusing the administrative connection to the SQLite database instead of creating a new one when wfGetDB() is called. Added LBFactory_Single to support this.
* Introduced a "schema variable" concept to DatabaseBase to avoid the use of globals for communication between the installer and the Database. Removed a lot of old global variable names from Database::replaceVars(), most were only added on a whim and were never used.
* Introduced DatabaseInstaller::getSchemaVars(), to allow schema variables to be supplied by the DatabaseInstaller child classes.
* Removed messages config-mysql-egine-mismatch [sic] and config-mysql-charset-mismatch. In the old installer it was possible for users to request a certain character set for an upgrade, but in the new installer the question is never asked. So these warnings were shown whenever a non-default character set or engine was used in the old database.
* In MysqlInstaller::preUpgrade(), fixed the incorrect strings used to identify the MySQL character sets: mysql5 instead of utf8 and mysql5-binary instead of binary.
* On install, initialise the site_stats table, using code copied from the old installer. Unlike the old installer, use SiteStats to increment the user count when the initial user is added.
* Fixed several instances of inappropriate call-by-reference.
* Replaced call_user_func_array() with call_user_func() where possible, it is shorter and simpler.
* Moved the caching boilerplate for DatabaseInstaller::getConnection() to the base class, and have the derived classes override an uncached function openConnection() instead. Updates r80892.
* In MysqlInstaller::getLocalSettings(), escape PHP strings correctly with LocalSettingsGenerator::escapePhpString().
* Reduce timeout for checks in dirIsExecutable() to 3 seconds, so that it doesn't take 30s to run when apache is in single-threaded mode for debugging.
* MySQL and SQLite have been tested and they appear to work. PostgreSQL upgrade is totally broken, apparently it was like that before I started. The Oracle code is untested.
* Added associated files for tooltip display
* Added associated css rules for tooltip display
* Updated installer's help system in (most?) places to display help as tooltips instead of show/hide system
* Beginnings of visual changes (e.g., less boxes, more color)
* Modified several of the installer's widget display methods
* Added a couple new i18n values
* Fixed small bug in installer logic:
- Password validation on new users was being executed even if there wasn't a $user object
* added Main Page creation within install
* added MEDIAWIKI_INSTALL constant; some scripts still use it
* started OracleUpgrader scripts for upgrade from 1.16
* fixed some not null defaults that comply with mysql data type default on not null fields
* FKs made defferable
* Add Status::getWikiTextArray() to allow different ways of formating a bunch of status messages (e.g. CLI output)
* Clean up messages in CliInstaller, use more i18n
* Use warning messages from Status return object in CLI installer
* Make Installer::isCompiled static so we don't have to create an object just to see that we can't use it.
* Add Installer::addInstallStepFollowing so we don't have MySQLInstaller mucking in its parent's data
* This is not complete yet, and should not be used outside of testing. Using it on a production database may ruin everything. This is the reason for the second entry point of new-index.php. You've been warned.
* Known issues are at [[mw:New-installer_issues]]. Please add new items to the list if you find them.
