Backward compatibility has been lost on Magento\Catalog\Model\ProductRepository class

[davidmolinacano]

Summary

I've a module that have a ProductRepository class which extends from the core Magento\Catalog\Model\ProductRepository class. We were calling the parent::__construct passing the Magento\Catalog\Controller\Adminhtml\Product\Initialization\Helper class which was required before Magento 2.4.7 as the 2nd parameter of the constructor, but now it has been removed and the second parameter must be Magento\Catalog\Api\Data\ProductSearchResultsInterfaceFactory class instead, thus losing the backward compatibility.

Examples

(Tested on Magento 2.4.3 after having removed the initialization helper from the parent::__construct)

Proposed solution

My proposal is to restore the Magento\Catalog\Controller\Adminhtml\Product\Initialization\Helper class as the second parameter. Although it's unused as you stated on the changelog, in my opinion it's required to guarantee the backward compatibility.

This bug can be reproduced by installing our module (version 0.13.13) on a Magento 2.4.7 and then executing a bin/magento setup:di:compile

Release note

Issue was caused by #37868, which actually fixed a bug by removing the dependency. Not sure if it will be easy to keep this fix and not break backwards compatibility.
The class is also not marked with @api, which means BC can be broken (even though we should really try to avoid it as much as we can)

Just my 2 cents, others are free to give their own opinions though 🙂

[davidmolinacano]

Thank you very much for the explanation @hostep ! Unfortunately, if this fix cannot be reverted we would need a proper solution for our specific case, because we must keep BC in our module since most of our customers are still using versions lower than 2.4.7, but a few of them are currently using the 2.4.7 too. If someone has any proposal about this issue, I'll be glad to hear it (well, in this case to read it).

[hostep]

So doofinder/doofinder-magento2@f9da4d2 is not fixing it?

We did use a solution like this in the past to be compatible with various magento versions with constructors that don't take the same amount of arguments: #30684 (comment)
It's a bit ugly, but it works and doesn't cause issues.

[davidmolinacano]

Unfortunately it didn't work as expected. Even with this fix, the setup:di:compile was still complaining about this. But thank you very much for pointing it, just in case.

[ihor-sviziev]

@davidmolinacano We can't just add back this parameter since it was already removed in 2.4.7. Just adding it back in 2.4.8 will cause backward incompatible change again. I think we should provide some workaround for this issue for you.

I guess the correct fix would be adding some if statement and compare magento version.

Unfortunately it didn't work as expected. Even with this fix, the setup:di:compile was still complaining about this.

Could you please provide some details which exception do you have? Also, would be great to get output from running a CLI command with the -vvv flag (verbose mode)

Of course, I'm pasting here the results of the command (Tested on Magento 2.4.7 and PHP 8.2):

Even forcing the if with false (just in case) it only takes into account the first statement and ignore the second one:

[sofia-doofinder]

Hello @ihor-sviziev, do you have any news about it? Could you test it, we are really block due to we can't put a if statement to differentiate the version...

[ihor-sviziev]

@sofia-doofinder, sorry, no updates
As to me, it looks like a bug in the Magento class validation.
I haven't had such issues.
As workaround, you can do not override constructor and get needed dependencies from object manager. I think that's the only option then unless it's fixed

The workaround example you can see in #38669 (comment)

[TuVanDev]

@davidmolinacano @sofia-doofinder @hostep @ihor-sviziev The approach of checking the current Magento version and serving the appropriate arguments of the parent method is working as expected.

I have reviewed the corresponding commit on the Doofinder repository and tested it in my own environment. During testing, I encountered the following error:

setup:di:compile

You may observe that the error message has changed. The issue was resolved by placing the $productMetadataInterface param before the optional params.

I have submitted a pull request to the Doofinder repository to fix this issue. doofinder/doofinder-magento2#317

@davidmolinacano This is my first time hearing about the Doofinder search feature, and it looks great. Keep up the good work!
There is an unused property, stockRegistry, in the Doofinder\Feed\Model\ProductRepository class. I recommend removing it to optimize your class.

[sofia-doofinder]

Hello @TuVanDev I'm checking you PR but it didn't work, as @davidmolinacano said the if seems not work at all...

I'm using your branch, and I'm using magento 2.4.3, when I run the comman setup:di:compile I got the following error:

Interception cache generation... 6/9 [==================>---------]  66% 26 secs 480.0 MiBErrors during compilation:
        Doofinder\Feed\Model\ProductRepository
                Incompatible argument type: Required type: \Magento\Catalog\Controller\Adminhtml\Product\Initialization\Helper. Actual type: \Magento\Catalog\Api\Data\ProductSearchResultsInterfaceFactory; File:

  Error during compilation  
                            

So it is saying that expect as required type \Magento\Catalog\Controller\Adminhtml\Product\Initialization\Helper, however is getting \Magento\Catalog\Api\Data\ProductSearchResultsInterfaceFactory

So it looks like is trying to load the if statment instead of access by the else, becuase is the first statment where is ignored the initializationHelper. So, looks like the if (version_compare($productMetadataInterface->getVersion(), '2.4.7', '>=')) return true, what can't be due to I'm using 2.4.3

The weired thing is that if I change the if to if (false) it still access by the first clausule beucase I receive the same error:

seems that the if is not workingn as expected because always tries to load the first statment....

[ihor-sviziev]

@TuVanDev @sofia-doofinder Can you try removing constructor override and try something like this instead?
#30684 (comment)

[sofia-doofinder]

thank you @ihor-sviziev I'm going to check

[TuVanDev]

Hi @sofia-doofinder , thanks for letting me know. I have reviewed the interception generation code and discovered that the ConstructorIntegrity validator class compares arguments between the current class and the parent class when a call parent::__construct() occurs.

• https://github.com/magento/magento2/blob/2.4.7/lib/internal/Magento/Framework/Code/Validator/ConstructorIntegrity.php#L88
• https://github.com/magento/magento2/blob/2.4.7/lib/internal/Magento/Framework/Code/Validator/ConstructorIntegrity.php#L85

As a result, the if else statements within the __construct() method were never reached while the ConstructorIntegrity class was validating class constructors.
Therefore, I have implemented @hostep 's solution, which involves removing the __construct() method and instantiating the necessary instances. I submitted another pull request to doofinder/doofinder-magento2 repository.

I have another solution, which is to rebuild your ProductRepository class based on the Magento\Catalog\Model\ProductRepository class without actually extending it. However, this approach has a drawback as it would involve manually implementing any changes made to the Magento\Catalog\Model\ProductRepository class into your own class whenever that file is updated.
