This is the 3rd minor release in the
v0.10.2-beta which only includes bug-fixes, this release also includes some refactoring to the main
lnd package that allows
lnd to more easily be embedded as a normal struct (by importing the package) on other Go projects.
Verifying the Release
In order to verify the release, you’ll need to have
gpg2 installed on your system. Once you’ve obtained a copy (and hopefully verified that as well), you’ll first need to import the keys that have signed this release if you haven’t done so already:
curl https://keybase.io/roasbeef/pgp_keys.asc | gpg --import
Once you have the required PGP keys, you can verify the release (assuming
manifest-v0.10.3-beta.rc1.txt.sig are in the current directory) with:
gpg --verify manifest-v0.10.3-beta.rc1.txt.sig
You should see the following if the verification was successful:
gpg: assuming signed data in 'manifest-v0.10.3-beta.rc1.txt' gpg: Signature made Mon Jun 29 17:11:22 2020 PDT gpg: using RSA key 4AB7F8DA6FAEBB3B70B1F903BC13F65E2DC84465 gpg: Good signature from "Olaoluwa Osuntokun <email@example.com>" [ultimate]
That will verify the signature of the manifest file, which ensures integrity and authenticity of the archive you’ve downloaded locally containing the binaries. Next, depending on your operating system, you should then re-compute the
sha256 hash of the archive with
shasum -a 256 <filename>, compare it with the corresponding one in the manifest file, and ensure they match exactly.
Verifying the Release Binaries
Our release binaries are fully reproducible. Third parties are able to verify that the release binaries were produced properly without having to trust the release manager(s). See our reproducible builds guide for how this can be achieved. The release binaries are compiled with
go1.13.12, which is required by verifiers to arrive at the same ones. They include the following build tags:
watchtowerrpc. Note that these are already included in the release script, so they do not need to be provided.
make release command can be used to ensure one rebuilds with all the same flags used for the release. If one wishes to build for only a single platform, then
make release sys=<OS-ARCH> tag=<tag> can be used.
Finally, you can also verify the tag itself with the following command:
git verify-tag v0.10.3-beta.rc1
Building the Contained Release
Users are able to rebuild the target release themselves without having to fetch any of the dependencies. In order to do so, assuming that
lnd-source-v0.10.3-beta.tar.gz are in the current directory, follow these steps:
tar -xvzf vendor.tar.gz tar -xvzf lnd-source-v0.10.3-beta.tar.gz GO111MODULE=on go install -v -mod=vendor -ldflags "-X github.com/lightningnetwork/lnd/build.Commit=v0.10.3-beta" ./cmd/lnd GO111MODULE=on go install -v -mod=vendor -ldflags "-X github.com/lightningnetwork/lnd/build.Commit=v0.10.3-beta" ./cmd/lncli
-mod=vendor flag tells the
go build command that it doesn’t need to fetch the dependencies, and instead, they’re all enclosed in the local vendor directory.
Additionally, it’s now possible to use the enclosed
release.sh script to bundle a release for a specific system like so:
make release sys="linux-arm64 darwin-amd64"
⚡️⚡️⚡️ OK, now to the rest of the release notes! ⚡️⚡️⚡️
lnd Package Refactoring
In prior releases, we’ve started to refactor the way
lnd is initialized and started to make it easier to emebdd
lnd in other Go applications. The primary consumer of these APIs so far has been our mobile bindings for
lnd. In this release we continue the process to further abstract the
lnd package with a series of PRs that remove a number of global variables, allow external sub-server registration, and external logging hooks.
