Race condition when doing a series of "duplicates" from one product

[TheCloneMaster]

Hi,

If you have another language loaded besides English, and do a series of duplicates from one "product" record, odoo will enter a race condition that will end up on "Exception: CPU time limit exceeded."

Steps to reproduce:
Check that you have installed another language besides English.
Open a product, and do a series of "duplicate" and "save". When you do this about 8 or 10 times, you will start noticing that duplication takes more and more time to complete.
If you continue duplicating and saving, you will end up with a nice "Exception: CPU time limit exceeded."

What version ?

My intuition is that it's not a race condition but a problem related to the duplication of ir_translation records each time you do it the size double so after n runs it take 2**n. For n=10 it's 1024 time the normal time.

Hi,

I am trying this on V. 8.0...

Yes, it is related to ir_translation, I saw that later on the logs...
But why is it doing a 2**n duplication of labels?

Mario

So, is this 2**n explosion of labels translated a known issue when duplicating products? Or any record ?

thanks @rvalyi for pointing me to this bug. I actually spent time to analyse the problem and I have a pull request #3304 for issue #3272 which is similar.
My PR only prevents the unwanted duplication, not the performance issue. (But there is no more performance issue when there is no duplication)

Thanks Christophe for the Fix, and Raphaël for his constant monitoring on
issues... ;-)

I will try this out and will report back...

After resolution of #3272 I cannot reproduce this 2**n explosion. I guess it's fixed.

I confirm it seems that less translations are duplicated.
I am closing this but let us know if you can still reproduce this issue.

Thanks Christophe and mart-e,

At least for our use case, it is gone. Will do some extra testing this weekend and will report back if any other issue arises...
