             Summary: PageSnapshot can contain wrong pageId tag when not dirty 
page is recycling
                 Key: IGNITE-9303
                 URL: https://issues.apache.org/jira/browse/IGNITE-9303
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.6
            Reporter: Aleksey Plekhanov


When page is recycling (for example in {{BPlusTree.Remove#freePage()}} -> 
{{DataStructure#recyclePage()}}) tag of {{pageId}} is modified, but original 
{{pageId}} is passed to {{writeUnlock()}} method and this passed {{pageId}} is 
stored to PageSnapshot WAL record.
This bug may lead to errors in WAL applying during crash recovery.

Reproducer (ignite-indexing module must be in classpath):

{code:java}
public class WalFailReproducer extends AbstractWalDeltaConsistencyTest {
    /** {@inheritDoc} */
    @Override protected boolean checkPagesOnCheckpoint() {
        return true;
    }

    /**
     *
     */
    public final void testPutRemoveCacheDestroy() throws Exception {
        CacheConfiguration<Integer, Integer> ccfg = new 
CacheConfiguration<>("cache0");
        ccfg.setIndexedTypes(Integer.class, Integer.class);

        IgniteEx ignite = startGrid(0);

        ignite.cluster().active(true);

        IgniteCache<Integer, Integer> cache0 = ignite.getOrCreateCache(ccfg);

        for (int i = 0; i < 5_000; i++)
            cache0.put(i, i);

        forceCheckpoint();

        for (int i = 1_000; i < 4_000; i++)
            cache0.remove(i);

        forceCheckpoint();

        stopAllGrids();
    }
}

{code}
