From bfa2e2b0fa93b6059fba0581b52d6d60a53b5a4a Mon Sep 17 00:00:00 2001 From: Randall Meyer Date: Wed, 15 Feb 2023 14:17:00 -0800 Subject: new flag: --connect-to Allows user to override DNS for the initial config request. This is accomplished using a custom DialContext overring the hostname used to Dial to. This allows for TLS certificate validation to still happen(optionally) while connecting to TLS secured resources. Also, - allows for optional enforcement of certificate verification - stamp built git version into binary and adds a --version option - adds a user-agent to all outgoing request - exit(1) on failures for easier shell error detection --- utilities/transport.go | 46 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 utilities/transport.go (limited to 'utilities/transport.go') diff --git a/utilities/transport.go b/utilities/transport.go new file mode 100644 index 0000000..2d70989 --- /dev/null +++ b/utilities/transport.go @@ -0,0 +1,46 @@ +/* + * This file is part of Go Responsiveness. + * + * Go Responsiveness is free software: you can redistribute it and/or modify it under + * the terms of the GNU General Public License as published by the Free Software Foundation, + * either version 2 of the License, or (at your option) any later version. + * Go Responsiveness is distributed in the hope that it will be useful, but WITHOUT ANY + * WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A + * PARTICULAR PURPOSE.
