Gateway timeout when doing bulk reset for +500 users

While doing a bulk password reset of +500 users I got a Gateway timeout. This is of course due to the settings of the hosting provider. However, I have now no means of determining which users did get a password reset and which did not.

I had logging switched on, no log was however written; I checked in the source code and it should have written it to the bulk-password-reset directory in the wordpress uploads folder.

So here are some tips:

• Fix logging
• Make the process resumable – you should be able to use one of the standard wordpress tables to maintain a last-processed-user counter.

As by standard, wordpress does not have a “last-changed-date” in the wp_users table, so I can’t tell which passwords were reset. All I can do now is sent out a manual mailing to all subscribers requesting them to manually reset their password.
