What happened to CatalogIndex module?

[kiatng]

There is no table associated to CatalogIndex in the db. And it seems the following always returns false:

magento-lts/app/code/core/Mage/CatalogIndex/Model/Aggregation.php

Lines 45 to 48 in 875661e

	protected function _isEnabled()
	{
	return Mage::app()->useCache(self::CACHE_FLAG_NAME);
	}

So, $data is always null here:

magento-lts/app/code/core/Mage/Catalog/Model/Layer/Filter/Attribute.php

Lines 111 to 113 in 875661e

	$data = $this->getLayer()->getAggregator()->getCacheData($key);
	if ($data === null) {

Is the CatalogIndex module dead?

I can't give you an answer. Is it a feature that has worked in the past? If so, then we have to check where we lost it on the way.

[fballiano]

what table are you searching for, so I'll check some old projects I have

[kiatng]

The tables are defined in the config.xml and created in the sql directory but in the latest version it's completely missing.

[fballiano]

@kiatng it is something that should stop us from releasing?

[kiatng]

No. I now think we should remove the module , may be in the next branch.

[sreichel]

@kiatng not tested ... is it possbly used with (non-)flat tables?

[kiatng]

I have both Use Flat Catalog Category and Use Flat Catalog Product set to No. No evidence that that CatalogIndex is used.

[fballiano]

I've enable both flat catalog and add some "die" to some catalogIndex files, it seems nothing from that module is run

[fballiano]

I've also removed all PHP files from that module, nothing seem to break in reindex phase, with or without flat.

[sreichel]

Mhh ... did you test it with active cart/catalog rules? My last idea where it could be used ...

[fballiano]

tested with catalog/cart rules, can't find any broken reindex. I'll do a PR on the next branch.

Note for future self, this is also related to #2758
