Improve performance of product category rewrites (disabled product & categories and product_use_categories)
Description (*)
- I fixed issues when it was set not to use „Categories Path for Product URLs” (product_use_categories) in configuration (Catalog → Catalog → Search Engine Optimizations) and yet they can be found in URL Rewrite Management (commit bfe932992f8498a1edbb9221a989f7da98f5c06e)
- I added field in configuration to set whether or not to generate rewrites for disabled categories and products (commit 9163a4d468ab93f42024c3677c251f1e5825a97a)

Excellent work @MarcinNowakMacopedia, thanks for contributing!
However, that is a lot of complex code changes to review with not many notes as to what bugs it fixes, what behaviors possibly changed, etc..
I did see the commit messages but a detailed description of the bugs, how to reproduce them, why your PR fixes the problems, what testing you've performed to ensure there are no regressions and some of the raw SQL before and after would really help us to review this and get it accepted much more readily.
We've been testing this PR in our development environment and the results are quite promising. We didn't see any issues arising from it and plan on deploying this into production soon. Thank you!
The most significant gains come from fixing the bug related to the catalog/seo/product_use_categories option. If people are using canonical urls for products then it's not really doing anything in terms of SEO (please correct me if I'm wrong). It's nice to have the product's URL matching the hierarchy during navigation but it's a trade-off we can accept to improve performance.
We have 99 store views with ~900 categories and ~20000 products. A single store view used to take us as much as 120 seconds to refresh and with this patch, ignoring disabled products/categories as well as disabling category-product urls, it can take between 15 to 25 seconds per store. This means we can reindex our entire store in 30 to 40 minutes.
It took quite some time but we finally started using this patch recently. We didn't make a full reindex yet but everything is working as it should for newer and updated products and categories.
In general I would propose this PR to be merged into the mainline OpenMage LTS.
The only change I would recommend, thinking of a wider audience, is to display a message, when switching product_use_categories from No to Yes, that reindexing URL Rewrites is recommended. I was even thinking that the original intention of still generating URLs was for a quicker transition and not actually an oversight (arguable but possible).
Reporting back with an issue we found using this PR. When the option to remove URLs of disabled products and categories is enabled, if you have a bunch of products that were disabled and enable them via a mass action the URLs will not be generated.

Reporting back with an issue we found using this PR. When the option to remove URLs of disabled products and categories is enabled, if you have a bunch of products that were disabled and enable them via a mass action the URLs will not be generated.
Mage_Catalog_Model_Indexer_Url didn't support mass action events. I have added this. Please check if it works now.
Sorry for my late answer. I hope it is still helpful.
Anyone want to test this on their staging environments and report back? I currently don't have a production-size instance to test with.
@colinmollenhour We've been using this PR for almost a year minus the changes that happened after my last message in October 2021. Even without the most recent changes that solve a couple of problems I reported, we have not encountered any breaking issues in our shop.
Currently, we only disabled Use Categories Path for Product URLs and kept generating the rewrites for disabled products/categories (due to the issue I previously reported with mass actions). I will create a task for my team to track the latest changes and report back ASAP.
We have 101 store views, ~32000 products and ~2500 categories (enabled and disabled). This has been an excellent patch for us.
@colinmollenhour I added Mage_Adminhtml_Model_System_Config_Backend_Seo to change the index status of categories and products after changing create_url_for_disabled in configuration. Additionally, I modified Mage_Adminhtml_Model_System_Config_Backend_Seo_Product to change product indexer status, after changing product_use_categories. https://github.com/OpenMage/magento-lts/pull/1405/commits/e33773c8c1e295271457c66bb14cf682b53f4d5b
@MarcinNowakMacopedia Are you able to look at my PR https://github.com/macopedia/magento-lts/pull/8? I am not able to push directly to your branch.
I'll close and reopen this PR since it's not "editable" by admins we can't fix anything in order to finish it.
