From c431bf3b0a740a8cec93a8ad721af48ede171e29 Mon Sep 17 00:00:00 2001 From: martinsumner Date: Fri, 21 Oct 2016 11:38:30 +0100 Subject: [PATCH] Broken snapshot test The test confirming that deleting sft files wer eheld open whilst snapshots were registered was actually broken. This test has now been fixed, as well as the logic in registring snapshots which had used ledger_sqn mistakenly rather than manifest_sqn. --- src/leveled_pclerk.erl | 4 ++-- src/leveled_penciller.erl | 4 ++-- src/leveled_sft.erl | 24 ++++++++++++++++-------- test/end_to_end/basic_SUITE.erl | 30 ++++++++++++++++++++---------- 4 files changed, 40 insertions(+), 22 deletions(-) diff --git a/src/leveled_pclerk.erl b/src/leveled_pclerk.erl index e008ea0..b9d7164 100644 --- a/src/leveled_pclerk.erl +++ b/src/leveled_pclerk.erl @@ -118,8 +118,8 @@ handle_call({manifest_change, confirm, Closing}, From, State) -> io:format("Prompted confirmation of manifest change~n"), gen_server:reply(From, ok), WI = State#state.work_item, - mark_for_delete(WI#penciller_work.unreferenced_files, - State#state.owner), + ok = mark_for_delete(WI#penciller_work.unreferenced_files, + State#state.owner), {noreply, State#state{work_item=null, change_pending=false}, ?MIN_TIMEOUT} diff --git a/src/leveled_penciller.erl b/src/leveled_penciller.erl index 1c69eee..3267421 100644 --- a/src/leveled_penciller.erl +++ b/src/leveled_penciller.erl @@ -490,7 +490,7 @@ handle_call(work_for_clerk, From, State) -> handle_call(get_startup_sqn, _From, State) -> {reply, State#state.ledger_sqn, State};
