* Added table option variable to the SQL patch files, so now upgrading a non-standard schema won't leave your database horribly corrupted.
* Added sql.php, for sourcing SQL files with MediaWiki variable substitution.
* Disable MySQL's strict mode at session start for MySQL 4.1+, to avoid the various problems that occur when it is on.

--- Experimental table definitions for MySQL 4.1 and 5.0 with
--- content-holding fields switched to explicit binary charset.
---
--- Binary is used instead of UTF-8 or UCS-2 so that all of
--- Unicode may be used as UTF-8 (MySQL still does not allow
--- use of characters outside the BMP in UTF-8 and has no UTF-16
--- support).
---
--- This should provide compatibility with our current MySQL 4.0
--- behavior (safe for full UTF-8, but ugly sorting) on newer
--- versions of MySQL server, without the conversion surprises
--- you get from piggybacking on "Latin-1" fields.
---
--- UTF-8 is used for the searchindex fields, as the fulltext index
--- doesn't seem to like the binary encoding.
---
--- Not fully tested, may have surprises!
---
--- TODO: Test various fields
-
--- ------------------------------------------------------------
-
--- SQL to create the initial tables for the MediaWiki database.
--- This is read and executed by the install script; you should
--- not have to run it by itself unless doing a manual install.
-
---
--- General notes:
---
--- If possible, create tables as InnoDB to benefit from the
--- superior resiliency against crashes and ability to read
--- during writes (and write during reads!)
---
--- Only the 'searchindex' table requires MyISAM due to the
--- requirement for fulltext index support, which is missing
--- from InnoDB.
---
---
--- The MySQL table backend for MediaWiki currently uses
--- 14-character CHAR or VARCHAR fields to store timestamps.
--- The format is YYYYMMDDHHMMSS, which is derived from the
--- text format of MySQL's TIMESTAMP fields.
---
--- Historically TIMESTAMP fields were used, but abandoned
--- in early 2002 after a lot of trouble with the fields
--- auto-updating.
---
--- The Postgres backend uses DATETIME fields for timestamps,
--- and we will migrate the MySQL definitions at some point as
--- well.
---
---
--- The /*$wgDBprefix*/ comments in this and other files are
--- replaced with the defined table prefix by the installer
--- and updater scripts. If you are installing or running
--- updates manually, you will need to manually insert the
--- table prefix if any when running these scripts.
---
-
-
---
--- The user table contains basic account information,
--- authentication keys, etc.
---
--- Some multi-wiki sites may share a single central user table
--- between separate wikis using the $wgSharedDB setting.
---
--- Note that when a external authentication plugin is used,
--- user table entries still need to be created to store
--- preferences and to key tracking information in the other
--- tables.

--- SQL to create the initial tables for the MediaWiki database.
--- This is read and executed by the install script; you should
--- not have to run it by itself unless doing a manual install.
-
---
--- General notes:
---
--- If possible, create tables as InnoDB to benefit from the
--- superior resiliency against crashes and ability to read
--- during writes (and write during reads!)
---
--- Only the 'searchindex' table requires MyISAM due to the
--- requirement for fulltext index support, which is missing
--- from InnoDB.
---
---
--- The MySQL table backend for MediaWiki currently uses
--- 14-character CHAR or VARCHAR fields to store timestamps.
--- The format is YYYYMMDDHHMMSS, which is derived from the
--- text format of MySQL's TIMESTAMP fields.
---
--- Historically TIMESTAMP fields were used, but abandoned
--- in early 2002 after a lot of trouble with the fields
--- auto-updating.
---
--- The Postgres backend uses DATETIME fields for timestamps,
--- and we will migrate the MySQL definitions at some point as
--- well.
---
---
--- The /*$wgDBprefix*/ comments in this and other files are
--- replaced with the defined table prefix by the installer
--- and updater scripts. If you are installing or running
--- updates manually, you will need to manually insert the
--- table prefix if any when running these scripts.

---
--- The user table contains basic account information,
--- authentication keys, etc.
---
--- Some multi-wiki sites may share a single central user table
--- between separate wikis using the $wgSharedDB setting.

--- user table entries still need to be created to store
--- preferences and to key tracking information in the other
--- tables.
