From 114afdaaf740b6a7c46b439d07f9f94158fc2dde Mon Sep 17 00:00:00 2001 From: Doug Coleman Date: Mon, 10 Nov 2014 19:03:50 -0800 Subject: [PATCH] forestdb.lib: Fix resource usage and cleanup. Reenable some snapshot tests but they expose bugs in forestdb, I think. --- extra/forestdb/lib/lib-tests.factor | 106 +++++++++------------------- extra/forestdb/lib/lib.factor | 64 ++++++++++------- 2 files changed, 73 insertions(+), 97 deletions(-) diff --git a/extra/forestdb/lib/lib-tests.factor b/extra/forestdb/lib/lib-tests.factor index 536105b188..44315172b8 100644 --- a/extra/forestdb/lib/lib-tests.factor +++ b/extra/forestdb/lib/lib-tests.factor @@ -2,62 +2,13 @@ !
