From daa22cacba823c8ad35d522252d8d1783823049f Mon Sep 17 00:00:00 2001 From: Ahmet Alp Balkan Date: Thu, 11 Jun 2015 15:30:18 -0700 Subject: [PATCH] storage/driver/azure: Update vendored Azure SDK This change refreshes the updated version of Azure SDK for Go that has the latest changes. I manually vendored the new SDK (github.com/Azure/azure-sdk-for-go) and I removed `management/` `core/` packages manually simply because they're not used here and they have a fork of `net/http` and `crypto/tls` for a particular reason. It was introducing a 44k SLOC change otherwise... This also undoes the `include_azure` flag (actually Steven removed the driver from imports but forgot to add the build flag apparently, so the flag wasn't really including azure. :smile: ). This also must be obsolete now. Fixes #620, #175.
