Hook actionCartUpdateQuantityBefore replaced by obsolete hook actionBeforeCartUpdateQty

[psyray]

Describe the bug

During module installation with the new actionCartUpdateQuantityBefore hook, this one is replaced by the obsolete actionBeforeCartUpdateQty which was commented in the cart class.
So the new hook actionCartUpdateQuantityBefore is never called.

This is caused by 2 bad behaviours during the hook registering of the module install :

• the alias contained in the hook_alias table
• the call to the deprecated getRetroHookName method during hook register

To Reproduce

Steps to reproduce the behavior:

1. Install a module with the actionCartUpdateQuantityBefore hook position
2. Hook position is replaced by actionBeforeCartUpdateQty during module installation

Fix

• Delete the alias record in the hook_alias table
  

OR

• Uncomment this line

OR

• Stop using the getRetroHookName method

Don't know what's the correct fix to use to provide a PR

Hi @psyray,

Thanks for your report.
I manage to reproduce the issue with PS1.7.5.1 & PS1.7.4.4.
In my module, I used the actionCartUpdateQuantityBefore hook.
mymodule.zip
In the BO => Design => Positions => the actionbeforecartupdateqty is used.

I’ll add this to the debug roadmap so that it’s fixed. If you have already fixed it on your end or if you think you can do it, please do send us a pull request!
Thanks!

I can't decide what's the good fix because I don't know your strategy about removing deprecated function.

For me the best fix is to remove the call to the getRetroHookName function at this line.
This could prevent another bug.

The more quickly is to uncomment this line.

You need to decide.

I believe this one is fixed by this PR: #12578
