LayoutsTreeImpl retrieves in memory al records, and afterwards applies pagination.

 

Steps to Reproduce:

1. Create a site named Site1
2. Add 21 public pages for Site1.
3. Execute the the following Groovy script (replace the value of groupId with Site1 identifier):

import com.liferay.portlet.layoutsadmin.util.LayoutsTreeUtil;
import com.liferay.portal.kernel.util.PortalUtil;
import com.liferay.portal.kernel.dao.orm.FinderCacheUtil;
import com.liferay.portal.kernel.dao.orm.FinderPath;
import com.liferay.portal.service.persistence.impl.LayoutPersistenceImpl;
import com.liferay.portal.kernel.service.LayoutLocalServiceUtil;
import com.liferay.portal.kernel.bean.PortalBeanLocatorUtil;
import com.liferay.portal.kernel.service.LayoutLocalService;
import com.liferay.portal.kernel.dao.orm.FinderPath;
import com.liferay.portal.model.impl.LayoutModelImpl;
import com.liferay.portal.service.persistence.impl.LayoutPersistenceImpl;
import com.liferay.portal.model.impl.LayoutImpl;
import com.liferay.portal.kernel.cache.MultiVMPoolUtil;
import com.liferay.portal.kernel.cache.PortalCache;
import com.liferay.portal.kernel.dao.orm.FinderCache;
import com.liferay.portal.kernel.util.OrderByComparator;


long groupId = 36939L;

String nonPaginatedCacheKey = getNonPaginatedCacheKey(groupId);
String paginatedCacheKey = getPaginatedCacheKey(groupId);

PortalCache portalCacheNonPaginated = MultiVMPoolUtil.getPortalCache(FinderCache.class.getName() + "." + LayoutPersistenceImpl.FINDER_CLASS_NAME_LIST_WITHOUT_PAGINATION);
PortalCache portalCachePaginated = MultiVMPoolUtil.getPortalCache(FinderCache.class.getName() + "." + LayoutPersistenceImpl.FINDER_CLASS_NAME_LIST_WITH_PAGINATION);

portalCacheNonPaginated.remove(nonPaginatedCacheKey);
portalCachePaginated.remove(paginatedCacheKey);

LayoutsTreeUtil.getLayoutsJSON(PortalUtil.getHttpServletRequest(actionRequest), groupId, "Tree");

out.println("Uses no pagination: " + !isNullOrEmpty(portalCacheNonPaginated.get(nonPaginatedCacheKey)));

out.println("Uses pagination: " + !isNullOrEmpty(portalCachePaginated.get(paginatedCacheKey)));


String getNonPaginatedCacheKey(long groupId) {
    boolean pagination = false;
    FinderPath finderPath = new FinderPath(LayoutModelImpl.ENTITY_CACHE_ENABLED, LayoutModelImpl.FINDER_CACHE_ENABLED, LayoutImpl.class,
                                LayoutPersistenceImpl.FINDER_CLASS_NAME_LIST_WITHOUT_PAGINATION, "findByG_P_P_Head",
                                [Long.class.getName(), Boolean.class.getName(), Long.class.getName(), Boolean.class.getName()] as String[],
                                LayoutModelImpl.GROUPID_COLUMN_BITMASK | LayoutModelImpl.PRIVATELAYOUT_COLUMN_BITMASK |
                                LayoutModelImpl.PARENTLAYOUTID_COLUMN_BITMASK | LayoutModelImpl.HEAD_COLUMN_BITMASK |
                                LayoutModelImpl.PRIORITY_COLUMN_BITMASK);

    Object[] finderArgs = [groupId, false, 0L, true];
    
    String encodedArguments = finderPath.encodeArguments(finderArgs);

    return finderPath.encodeCacheKey(encodedArguments);
}

String getPaginatedCacheKey(long groupId) {
    boolean pagination = true;
    FinderPath finderPath = new FinderPath(LayoutModelImpl.ENTITY_CACHE_ENABLED, LayoutModelImpl.FINDER_CACHE_ENABLED, LayoutImpl.class,
                     LayoutPersistenceImpl.FINDER_CLASS_NAME_LIST_WITH_PAGINATION, "findByG_P_P_Head",
                     [Long.class.getName(), Boolean.class.getName(), Long.class.getName(), Boolean.class.getName(),
                     Integer.class.getName(), Integer.class.getName(), OrderByComparator.class.getName()] as String[]);

    Object[] finderArgs = finderArgs = [groupId, false, 0L, true, 0, 20, null];

    String encodedArguments = finderPath.encodeArguments(finderArgs);

    return finderPath.encodeCacheKey(encodedArguments);
}

boolean isNullOrEmpty(Collection collection) {
    return collection == null || collection.isEmpty();
}

Expected Results:

The script should indicate the following:

Uses no pagination: false
Uses pagination: true

Actual Results:

The script indicates the following:

Used no pagination: true
Used pagination: false

What the script does is the following:

1. Calls LayoutsTreeImpl
2. Checks if the cache contains a record based on pagination
3. Checks if the cache contains a record not based on pagination.
