* Remove last of $wgDBuser-specific settings like timezone, datestyle and search_path. This is all handled by open() :D
* Only set search_path if the schema exists (rather than just set to some random string), fall back to 'public' otherwise
* Only call setupUser() if we need to _CreateDBAccount, otherwise it returns immediately and confuses you (no functional change)
* Implement selectDB() for Postgres, basically call open() with a new DB name
* Try to fix setupDatabase() for this "user must be owner of relation" error I'm getting when the $wgDBuser exists (have tried with roles granted && no roles granted). I get no errors at all when
* NOTE: this commit removes any semblence of tsearch compatibility with pre-8.3 PostgreSQL
* Make new-installer work against PostgreSQL
* Remove SearchPostgres.php's call to pg_fetch_result. I think this is the only one outside of the vestigtial old installer code.
** 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.
* Add user creation form like MySQL
* Fix canCreateAccounts() check
* Fix ts2 setup callback
* Still needs schema creation and other misc. stuff from lines ~370-530 of DatabasePostgres
* Ported canCreateAccounts() check
* Moved creation of new user to setupUser()
* Moved DB creation (still needs schema stuff) to setupDatabase() where it belongs
* Added ts2 setup
TODO:
* UI for non-admin account (like MysqlInstaller::getSettingsForm) and maybe move ts2 and other "optional" settings there
* Schema creation/setup
* Set up and use function for renaming tables
* Use $conn instead of $this when it is called for
* remove protection from commitChanges so the installer can use it
* Move setup_database() from DatabasePostgres to PostgresInstaller
** Add install step after interwiki for the COMMIT
** Put the table creation test (should we abstract this?) in setupDatabase()
** The leftover stuff in initial_setup() also belongs in setupDatabase(), I think?
* 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
