WordPress database error Duplicate entry

Hi @epsiloncool, so I’ve updated to 1.71.238 today and now am seeing lots of these in my PHP error log:

What should I do, please?

…and I’ve just noticed it’s not returning any searches anymore. I’ll try reverting back to the previous version.

(@epsiloncool)

Thank you very much for the fast report! It’s actually the strange problem and we didn’t detect it on the testing stage…. ??

Could you please make a simple test for me?

Please deactivate 1.71.238 and then activate it again. Then open the error_log and tell me whether there is a fresh error message at the moment of activation. The plugin is checking for all the tables and in case some tables not exist, it creates them. In this exact case I see that wpftsi_doctree was not created automatically and I think there was some error why it was not happen.

Let me know if you see some error in error_log in the moment of plugin activation.

Thanks!

(@rfischmann)

Thanks for the quick reply, @epsiloncool!

So I deactivated the plugin, updated it again to the latest version, and re-activated it.

This time, I’m not seeing any error logs and it seems to be working fine. Maybe now it did create the new DB table on activation, but didn’t do that before when I simply updated over the previous version while it was already activated?

Cheers!

(@rfischmann)

I’ve just connected to my DB using Sequel Pro and can confirm the wpftsi_doctree table was now created.

Plugin Author

(@epsiloncool)

Good that the plugin is working now, but it’s bad that the bad is disappear silently.

Could you please open your error_log again and find the datetime where you have updated the plugin for the first time? There should be an error message and I still hope to see it.

You can try try to search for “create table” or “alter column” or “alter table” sentences…

Thank you!

(@rfischmann)

Just looked at it and the first error, right after I updated the plugin, was very similar to the one I’ve pasted above @epsiloncool. Then, the error log started getting flooded by various similar entries like that until I reverted back to the previous version.

Would those DB errors really be in that same PHP error.log file or maybe in another one?

Plugin Author

(@epsiloncool)

There is only one common error_log file for all scripts and plugins. Also in WPFTS we are not recording script/db errors to somewhere else.

Okay, Rafael, I got enough information. I suspect that plugin activation while updating comes by different way than on the manual deactivation/activation. And the result is mandatory table was not created.

I am going to make more serious tests around this problem.

Thank you again!

There are a few of these.

Those MySQL queries looks near to usual, so may be it is not a problem of WPFTS plugin. For example, first query is 100% good and even can be used by other plugins. Do you see any other database-related errors from other plugins or tables?

As I know, database errors related to “Lock wait timeout exceeded” may happen when two different processes is trying to access the same database row(s). But it’s normal situation, MySQL server is the thing that is designed to solve such things silently.

However, there is a setting in database config that says to MySQL how much lock wait time is “OKAY”. It is called “innodb_lock_wait_timeout” and it is set to 50 seconds by default.

If we set it to smaller value, for example, 1 second, MySQL will recognize even small row locks as problems.

May I ask you something? Could you try to check which value is set on your MySQL?

Make this query in phpMyAdmin or somewhere else with your website database

select @@innodb_lock_wait_timeout

It should show a value in results, show it to me.

Thanks a lot!

I see, thanks @epsiloncool.

My “innodb_lock_wait_timeout” is set to 50 seconds, as you said.

Here are no other errors in my logs besides those two I’ve pasted above, which are repeating every now and then.

Thanks, I am actually still looking for a solution. The problem is: I can not repeat the problem on my dev environment nor on other my websites. But I am checking for other developer experience and making tests.

This error log message should not make problem on a basic plugin functions. Do you see some problem?

Thanks.
