Re: [Libguestfs] [PATCH libnbd 1/2] golang: Create distribution for a proxy server

Add make-dist.sh script, creating a distribution tree for a proxy server[1]. The created tree must be served by the web server serving the libnbd module, for example: https://download.libguestfs.org/libnbd-golang The Go tools will find this URL by looking at: https://libguestfs.org/linbd

Which serve html document with the "go-import" meta tag, pointing to the server serving the module. When the module is available, we need to register the package here: https://pkg.go.dev/libguestfs.org/libnbd [1] https://golang.org/ref/mod#serving-from-proxy Signed-off-by: Nir Soffer <nsoffer(a)redhat.com&gt; --- golang/make-dist.sh | 123 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 123 insertions(+) create mode 100755 golang/make-dist.sh diff --git a/golang/make-dist.sh b/golang/make-dist.sh new file mode 100755 index 0000000..634e306 --- /dev/null +++ b/golang/make-dist.sh @@ -0,0 +1,123 @@ +#!/bin/sh -e +# nbd client library in userspace +# Copyright (C) 2021 Red Hat Inc. +# +# This library is free software; you can redistribute it and/or +# modify it under the terms of the GNU Lesser General Public +# License as published by the Free Software Foundation; either +# version 2 of the License, or (at your option) any later version. +# +# This library 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.
