From d36f3b0ab48aced7668974530549004b4f16075f Mon Sep 17 00:00:00 2001 From: Patrik Nyblom Date: Fri, 13 Aug 2010 15:59:33 +0200 Subject: Remove binary overhead counter from ets objects As the overhead counter got larger and never really was needed in ets objects, I removed them. A few stray comments of XXX:PaN type from halfword dev removed in the process. --- erts/emulator/beam/erl_db_hash.c | 14 ++++++++++---- 1 file changed, 10 insertions(+), 4 deletions(-) (limited to 'erts/emulator/beam/erl_db_hash.c') diff --git a/erts/emulator/beam/erl_db_hash.c b/erts/emulator/beam/erl_db_hash.c index 08117bb6e5..5abd2e50fa 100644 --- a/erts/emulator/beam/erl_db_hash.c +++ b/erts/emulator/beam/erl_db_hash.c @@ -2745,6 +2745,7 @@ static void db_finalize_dbterm_hash(DbUpdateHandle* handle) ASSERT(&oldp->dbterm == handle->dbterm); if (handle->mustResize) { + ErlOffHeap tmp_offheap; Eterm* top; Eterm copy; DbTerm* newDbTerm; @@ -2755,14 +2756,15 @@ static void db_finalize_dbterm_hash(DbUpdateHandle* handle) newDbTerm = &newp->dbterm; newDbTerm->size = handle->new_size; - newDbTerm->off_heap.first = NULL; - newDbTerm->off_heap.overhead = 0; + tmp_offheap.first = NULL; + tmp_offheap.overhead = 0; /* make a flat copy */ top = DBTERM_BUF(newDbTerm); copy = copy_struct(make_tuple(handle->dbterm->tpl), handle->new_size, - &top, &newDbTerm->off_heap); + &top, &tmp_offheap); + newDbTerm->first_oh = tmp_offheap.first; DBTERM_SET_TPL(newDbTerm,tuple_val(copy)); WUNLOCK_HASH(lck); @@ -2805,7 +2807,11 @@ void db_foreach_offheap_hash(DbTable *tbl, for (i = 0; i < nactive; i++) { list = BUCKET(tb,i); while(list != 0) { - (*func)(&(list->dbterm.off_heap), arg); + ErlOffHeap tmp_offheap; + tmp_offheap.first = list->dbterm.first_oh; + tmp_offheap.overhead = 0; + (*func)(&tmp_offheap, arg); + list->dbterm.first_oh = tmp_offheap.first; list = list->next; } } -- cgit v1.2.3
