From 6f01e802d2718e78a423d8ef16167778b8c20e68 Mon Sep 17 00:00:00 2001 From: Liz Marley Date: Wed, 18 Jan 2012 16:40:16 -0800 Subject: [PATCH 1/6] Got digest authentication working again. (It broke sometime after the 0.5 gem.) digest_auth needs the result from the first naive request in order to build the proper headers for digest authentication. --- lib/net/dav.rb | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/lib/net/dav.rb b/lib/net/dav.rb index 22d4a44..663aaba 100644 --- a/lib/net/dav.rb +++ b/lib/net/dav.rb @@ -156,8 +156,6 @@ def handle_request(req, headers, limit = MAX_REDIRECTS, &block) case @authorization when :basic req.basic_auth @user, @pass - when :digest - digest_auth(req, @user, @pass, response) end response = nil @@ -186,6 +184,8 @@ def handle_request(req, headers, limit = MAX_REDIRECTS, &block) @authorization = :basic else @authorization = :digest + # use the response from the failed request to build proper digest headers so we can try again + digest_auth(req, @user, @pass, response) end return handle_request(req, headers, limit - 1, &block) when Net::HTTPRedirection then From d1ee30298a2968aedf07e4dfc80645c0d7916638 Mon Sep 17 00:00:00 2001 From: Liz Marley Date: Fri, 20 Jan 2012 14:41:03 -0800 Subject: [PATCH 2/6] Instead of imitating github.com/drbrain/net-http-digest_auth, just use it. This improves performance because only the first request will have to try, get HTTPUnauthorized, and retry.
