Description

The CREATE TABLE statements in wp-admin/includes/schema.php don't use IF NOT EXISTS so they create lots of SQL errors every time you update the network.

Can you describe the rest of the error? For what query is it failing, what's the backtrace and when exactly does it occur?

These statements do not use IF NOT EXISTS because they go through dbDelta(), which handles various DB upgrades (new indexes, new or changed fields, new tables). These are not SQL statements that are directly and unconditionally run.

Replying to nacin:

Can you describe the rest of the error? For what query is it failing, what's the backtrace and when exactly does it occur?

These statements do not use IF NOT EXISTS because they go through dbDelta(), which handles various DB upgrades (new indexes, new or changed fields, new tables). These are not SQL statements that are directly and unconditionally run.

I can confirm this error.

When upgrading our multisite install from v3.4.2 to v3.5.1, we encountered a lof of these errors too.

The errors occurred when performing the network upgrade (/wp-admin/network/upgrade.php), and they occurred for each and every blog on the install that was upgraded (in our case 37 blogs).

In other words, every time a sub blog's database was upgraded (by hitting /wp-admin/upgrade.php?step=upgrade_db), it generated the following database errors:

WordPress database error Table 'wp_users' already exists for query CREATE TABLE wp_users (\n  ID bigint(20) unsigned NOT NULL auto_increment,\n  user_login varchar(60) NOT NULL default '',\n  user_pass varchar(64) NOT NULL default '',\n  user_nicename varchar(50) NOT NULL default '',\n  user_email varchar(100) NOT NULL default '',\n  user_url varchar(100) NOT NULL default '',\n  user_registered datetime NOT NULL default '0000-00-00 00:00:00',\n  user_activation_key varchar(60) NOT NULL default '',\n  user_status int(11) NOT NULL default '0',\n  display_name varchar(250) NOT NULL default '',\n  spam tinyint(2) NOT NULL default '0',\n  deleted tinyint(2) NOT NULL default '0',\n  PRIMARY KEY  (ID),\n  KEY user_login_key (user_login),\n  KEY user_nicename (user_nicename)\n) DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci made by wp_upgrade, make_db_current_silent, dbDelta

So it looks like each sub-blog database upgrade caused the multisite installation's global tables to be created even though they already existed.

Our multisite install was originally a WPMU install which has been upgraded to multisite in 3.0 and upgraded to each version since then.

For multisite installs that have 1000 of blogs, this would cause (8 x 1000 = 8000) MySQL CREATE TABLE errors.

It seems strange that dbDelta isn't detecting that those global multisite tables already exist.

WordPress 3.5.2, Multi Site.

  • Version set to 3.0.1

Adding some more background info -- I've been investigating this as we're getting ready to upgrade a MU-era install from 3.1.4 to 3.6.1 and we're encountering the same warnings.

It looks like this has actually been an issue since 3.0.1 due to the logic fliespl describes in #22791. Warnings were triggered during upgrades of non-root blogs as the CREATE TABLE statements for global tables (wp_users and wp_usermeta at the time) hung around due to the continue statement on line 1538 of wp-admin/includes/upgrade.php.

We just didn't notice anything until 3.5 as that's when checks before error_log'ing were removed in WP_DB::print_error().

In 3.3 it got a bit worse due to logic changes in make_db_current* in wp-admin/includes/upgrade.php -- the calls to dbDelta started including the MS global tables at that time.

I'd love to add some unit tests as proof but dbDelta is tricky to test as it's written. I can confirm that 22134-b.patch fixes the issue.

Any chance this could get looked at? We have 1495 sites over 29 networks (and growing) and the unneccessary CREATE statements / warnings are adding 10+ minutes to the upgrade procedure.

We don't actually have to bother with the DESCRIBE as we'll never be creating these tables outside the context of is_main_site().
