From 7a380deff74ac20e1fec7c6a92f186b0c1adbfe3 Mon Sep 17 00:00:00 2001 From: Yi Wu Date: Wed, 14 Jun 2017 13:08:54 -0700 Subject: [PATCH] Update blob_db_test Summary: I'm trying to improve unit test of blob db. I'm rewriting blob db test. In this patch: * Rewrite tests of basic put/write/delete operations. * Add disable_background_tasks to BlobDBOptionsImpl to allow me not running any background job for basic unit tests. * Move DestroyBlobDB out from BlobDBImpl to be a standalone function. * Remove all garbage collection related tests. Will rewrite them in following patch. * Disabled compression test since it is failing. Will fix in a followup patch.
