From 345878a7fbdf093158cf22251f51263099648770 Mon Sep 17 00:00:00 2001 From: Yi Wu Date: Tue, 30 May 2017 22:16:32 -0700 Subject: [PATCH] update blob_db_test Summary: Re-enable blob_db_test with some update: * Commented out delay at the end of GC tests. Will update the logic later with sync point to properly trigger GC. * Added some helper functions. Also update make files to include blob_dump tool.
