Example 1 with PageCacheConfig

use of org.neo4j.test.rule.PageCacheConfig in project neo4j by neo4j.

the class GBPTreeTest method skipFlushingPageFileOnCloseWhenPageFileMarkForDeletion.

@Test

    var tracer = new DefaultPageCacheTracer();
    PageCacheConfig config = config().withTracer(tracer);
    long initialPins = tracer.pins();

        GBPTree<MutableLong, MutableLong> tree = index(pageCache).with(RecoveryCleanupWorkCollector.ignore()).with(tracer).build()) {
        List<PagedFile> pagedFiles = pageCache.listExistingMappings();
        assertThat(pagedFiles).hasSize(1);
        long flushesBefore = tracer.flushes();
        PagedFile indexPageFile = pagedFiles.get(0);
        indexPageFile.setDeleteOnClose(true);
        tree.close();
        assertEquals(flushesBefore, tracer.flushes());
        assertEquals(tracer.pins(), tracer.unpins());
        assertThat(tracer.pins()).isGreaterThan(initialPins);
