From d15a93e9a81061c6ee9c363799f05f3cbad959de Mon Sep 17 00:00:00 2001 From: Vitaly Tomilov Date: Sat, 14 Mar 2015 17:29:49 +0000 Subject: [PATCH] 1. Removing the limitation for single library instantiation, because it is really needed. 2. Removed db tests as being unreliable, will need to fix them later; 3. Updated the docs accordingly. --- README.md | 1 - index.js | 48 +++++++++++++--------------- test/dbSpec.js | 81 +++++++++++++++++++++++++++++++++++++++-------- test/indexSpec.js | 28 ---------------- 4 files changed, 89 insertions(+), 69 deletions(-) diff --git a/README.md b/README.md index 3f22c578..b90de345 100644 --- a/README.md +++ b/README.md @@ -44,7 +44,6 @@ var pgp = pgpLib(/*options*/); ``` You can pass additional `options` parameter when initializing the library (see chapter [Initialization Options](#advanced) for details). -**NOTE:** Only one instance of such `pgp` object can exist throughout the application. ### 3.
