示例1: run
void run() {
NamespaceDetails* nsd = nsdetails( _ns );
// _id_ is at 0, so nIndexes == 1
IndexCatalog::IndexBuildBlock* a = halfAddIndex("a");
IndexCatalog::IndexBuildBlock* b = halfAddIndex("b");
IndexCatalog::IndexBuildBlock* c = halfAddIndex("c");
IndexCatalog::IndexBuildBlock* d = halfAddIndex("d");
int offset = nsd->findIndexByName( "b_1", true );
ASSERT_EQUALS(2, offset);
delete b;
ASSERT_EQUALS(2, nsd->findIndexByName( "c_1", true ) );
ASSERT_EQUALS(3, nsd->findIndexByName( "d_1", true ) );
offset = nsd->findIndexByName( "d_1", true );
delete d;
