PHPXRef 0.7 : Drupal 6 (gatewave) : Detail view of system.install

This update used to add an index on users created column (#127941).
However, system_update_1022() does the same thing.  This update
tried to detect if 1022 had already run but failed to do so,
resulting in an "index already exists" error.

Adding the index here is never necessary.  Sites installed before
1022 will run 1022, getting the update.  Sites installed on/after 1022
got the index when the table was first created.  Therefore, this
function is now a no-op.

system_update_6005() X-Ref

Add language to url_alias table and modify indexes.

system_update_6006() X-Ref

Drop useless indices on node_counter table.

system_update_6007() X-Ref

Change the severity column in the watchdog table to the new values.

system_update_6008() X-Ref

Add info files to themes. The info and owner columns are added by
update_fix_d6_requirements() in update.php to avoid a large number
of error messages from update.php. All we need to do here is copy
description to owner and then drop description.

system_update_6009() X-Ref

The PHP filter is now a separate module.

system_update_6010() X-Ref

Add variable replacement for watchdog messages.

The variables field is NOT NULL and does not have a default value.
Existing log messages should not be translated in the new system,
so we insert 'N;' (serialize(NULL)) as the temporary default but
then remove the default value to match the schema.

system_update_6011() X-Ref

Add language support to nodes

system_update_6012() X-Ref

Add serialized field to cache tables. This is now handled directly
by update.php, so this function is a no-op.

system_update_6013() X-Ref

Rebuild cache data for theme system changes

system_update_6014() X-Ref

Record that the installer is done, so it is not
possible to run the installer on upgraded sites.

system_update_6015() X-Ref

Add the form cache table.

system_update_6016() X-Ref

Make {node}'s primary key be nid, change nid,vid to a unique key.
Add primary keys to block, filters, flood, permission, and term_relation.

system_update_6017() X-Ref

Rename settings related to user.module email notifications.

system_update_6018() X-Ref

Add HTML corrector to HTML formats or replace the old module if it was in use.

system_update_6019() X-Ref

Reconcile small differences in the previous, manually created mysql
and pgsql schemas so they are the same and can be represented by a
single schema structure.

Note that the mysql and pgsql cases make different changes.  This
is because each schema needs to be tweaked in different ways to
conform to the new schema structure.  Also, since they operate on
tables defined by many optional core modules which may not ever
have been installed, they must test each table for existence.  If
the modules are first installed after this update exists the tables
will be created from the schema structure and will start out
correct.

system_update_6020() X-Ref

Create the tables for the new menu system.

system_update_6021() X-Ref

Migrate the menu items from the old menu system to the new menu_links table.

system_update_6022() X-Ref

Update files tables to associate files to a uid by default instead of a nid.
Rename file_revisions to upload since it should only be used by the upload
module used by upload to link files to nodes.

system_update_6023() X-Ref

No description

system_update_6024() X-Ref

Add translation fields to nodes used by translation module.

system_update_6025() X-Ref

Increase the maximum length of node titles from 128 to 255.

system_update_6026() X-Ref

Display warning about new Update status module.

system_update_6027() X-Ref

Add block cache.

system_update_6028() X-Ref

Add the node load cache table.

system_update_6029() X-Ref

Enable the dblog module on sites that upgrade, since otherwise
watchdog logging will stop unexpectedly.

system_update_6030() X-Ref

Add the tables required by actions.inc.

system_update_6031() X-Ref

Ensure that installer cannot be run again after updating from Drupal 5.x to 6.x
Actually, this is already done by system_update_6014(), so this is now a no-op.

system_update_6032() X-Ref

profile_fields.name used to be nullable but is part of a unique key
and so shouldn't be.

system_update_6033() X-Ref

Change node_comment_statistics to be not autoincrement.

system_update_6034() X-Ref

Rename permission "administer access control" to "administer permissions".

system_update_6035() X-Ref

Change index on system table for better performance.

system_update_6036() X-Ref

Change the search schema and indexing.

The table data is preserved where possible in MYSQL and MYSQLi using
ALTER IGNORE. Other databases don't support that, so for them the
tables are dropped and re-created, and will need to be re-indexed
from scratch.

system_update_6037() X-Ref

Create consistent empty region for disabled blocks.

system_update_6038() X-Ref

Ensure that "Account" is not used as a Profile category.

system_update_6039() X-Ref

Rename permissions "edit foo content" to "edit any foo content".
Also update poll module permission "create polls" to "create
poll content".

system_update_6040() X-Ref

Add a weight column to the upload table.

system_update_6041() X-Ref

Change forum vocabulary not to be required by default and set the weight of the forum.module 1 higher than the taxonomy.module.

system_update_6042() X-Ref

Upgrade recolored theme stylesheets to new array structure.

system_update_6043() X-Ref

Update table indices to make them more rational and useful.

system_update_6044() X-Ref

RC1 to RC2 index cleanup.

system_update_6045() X-Ref

Update blog, book and locale module permissions.

Blog module got "edit own blog" replaced with the more granular "create
blog entries", "edit own blog entries" and "delete own blog entries"
permissions. We grant create and edit to previously privileged users, but
delete is not granted to be in line with other permission changes in Drupal 6.

Book module's "edit book pages" was upgraded to the bogus "edit book content"
in Drupal 6 RC1 instead of "edit any book content", which would be correct.

Locale module introduced "administer languages" and "translate interface"
in place of "administer locales".

Modeled after system_update_6039().

system_update_6046() X-Ref

Ensure that the file_directory_path variable is set (using the old 5.x
default, if necessary), so that the changed 6.x default won't break
existing sites.

system_update_6047() X-Ref

Fix cache mode for blocks inserted in system_install() in fresh installs of previous RC.

system_update_6048() X-Ref

Increase the size of the 'load_functions' and 'to_arg_functions' fields in table 'menu_router'.

system_update_6049() X-Ref

Replace src index on the {url_alias} table with src, language.

system_update_6050() X-Ref

Clear any menu router blobs stored in the cache table.

system_update_6051() X-Ref

Create a signature_format column.

system_update_6052() X-Ref

Add a missing index on the {menu_router} table.
