* In SqlBagOStuff, ignore errors due to a read-only database, per my comments on CR r42796. Same for LocalisationCache.
* Merged SqlBagOStuff and MediaWikiBagOStuff, that proved to be an awkward and unnecessary generalisation. Use the standard quoting wrapper functions instead of $db->query().
* Implemented atomic incr() and decr() functions for SqlBagOStuff.
* Made incr() and decr() generally work roughly the same as it does in memcached, respecting negative steps instead of ignoring such operations. This allows decr() to be implemented in terms of incr().
* Per bug 11533, in MessageCache.php, don't retry 20 times on a cache failure, that's really memcached-specific and won't be useful for other cache types. It's not really very useful for memcached either.
* Moved MySQL-specific implementations of wasDeadlock() and wasErrorReissuable() to DatabaseMysql.
* Briefly tested page views with $wgReadOnly=read_only=1, fixed an error from Article::viewUpdates(). A CentralAuth fix will be in a subsequent commit.
Also make it abstract in DatabaseBase so all subclasses have to implement some human readable name
(also make getSoftwareLink abstract for the same reason) Every current Database class already implements both.
Notably, this will switch conditional() in MySQL from using IF() to
using CASE, like all other DBMSes. Documentation suggests this works
back to 4.0. If it's a problem, it's a matter of a few lines to
override it in DatabaseMysql.php.
Also, some extra explanatory comments have been added to a number of
methods in DatabaseBase.
Specifically freeResult(), selectDB(), close(), and ping(), as suggested
by Tim on code review for r51918. Where these were overridden by stubs
in subclasses, I deleted the stubs.
All other databases were changed to extend DatabaseBase instead of
Database. Database was kept as an alias for DatabaseMysql for
compatibility. Existing explicit references to Database that I could
find were changed to DatabaseMysql for the sake of clarity.
Should cause no functional changes.
* removing the indexName() hack and with it the /*i*/ stuff from tables.sql
* undoing renames of formerly implicitly named indices
* three indices have to be called different in SQLite because of naming conflicts, adding a patch to updaters.inc that does that
* Made the upgrader work with SQLite
* Implemented missing schema info functionality in DatabaseSqlite
* Merged the SQLite and MySQL schemas into the one file with the help of some replaceVars() hacks.
* Moved all primary key definitions to the field definition, moved all indexes to CREATE INDEX statements, for best SQLite compatibility.
* Made all autoincrement fields primary keys, as required by SQLite.
* Removed meaningless buzzword from the category table comment
* tables.sql: s/'0'/0/
* In SQLite the index names have DB scope. Renamed archive.usertext_timestamp, user_newtalk.user_id, user_newtalk.user_ip
* SQLite does not support UPDATE with LIMIT by default. Removed all instances I could find.
* Made query errors work in the installer.
* Fixed DatabaseSqlite::lastErrno(), made SQLITE_SCHEMA errors automatically reissue the query as suggested on sqlite-users. Otherwise upgrade breaks.
* Removed miscellaneous status information from getServerVersion(), that's not the place to put it
* Don't call quickUserCan('edit') unless section edit is enabled
* In DatabasePostgres and DatabaseSqlite: throw an exception on connection error
* In DatabasePostgres: don't send an invalid connection string whenever one of the fields is empty. Use quoting.
* In Database: make the captured PHP error prettier
* Display a descriptive error message when the user navigates to index.php with PHP 4, not a parse error. Check to see if the *.php5 extension works, using file_get_contents().
* The default port number for PostgreSQL is 5432, not blank.
* Better default for $wgDBname
or Database::newFromParams() explicitly at the moment. While that's already bad (breaking PG support etc), I'd rather see those get fixed before we go introducing differences between Database and DatabaseMySql.
* Wrote a tool to check the integrity of the autoloader class list, fixed some issues that came up.
* Start the autoloader before LocalSettings.php, so that when an extension writer thinks an inefficient one-file special page extension is the way to go, they don't have to use explicit includes to make the class inheritance work. Should continue to work with $IP set in LocalSettings.php as long as $IP is set before extensions are included.
