This marks the second public release of poold, and the first minor release after the initial public release. This release contains no new features. Instead, this release packages a number of important bug fixes related to account management, and worst-case order execution cost estimation.

Verifying the Release

In order to verify the release, you'll need to have gpg or 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-v0.3.3-alpha.txt and manifest-v0.3.3-alpha.txt.sig are in the current directory) with:

gpg --verify manifest-v0.3.3-alpha.txt.sig

You should see the following if the verification was successful:

gpg: assuming signed data in 'manifest-v0.3.3-alpha.txt'
gpg: Signature made Thu Nov 12 16:31:37 2020 PST
gpg:                using RSA key 60A1FA7DA5BFF08BDCBBE7903BBD59E99B280306
gpg: Good signature from "Olaoluwa Osuntokun <laolu32@gmail.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 go1.15.3, which is required by verifiers to arrive at the same ones.

The 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:

The signature on the tag itself can be verified with:

git verify-tag v0.3.3-alpha

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 vendor.tar.gz and poold-source-v0.3.3-alpha.tar.gz are in the current directory, follow these steps:

tar -xvzf vendor.tar.gz
tar -xvzf lnd-source-v0.3.3-alpha.tar.gz
GO111MODULE=on go install -v -mod=vendor ./cmd/poold
GO111MODULE=on go install -v -mod=vendor ./cmd/pool

The -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"

Release Notes

CLI Commands

The pool orders list command will now default to only showing active orders.

Documentation

The docs have been updated to show the proper name of the config file for poold.

Account Management & Order Handling

An edge case has been fixed that would otherwise cause an account to partially apply an update. We'll now ensure that we obtain all signatures from the auctioneer before we commit the new state to disk.

We'll now properly round up the min channel amt to the nearest unit, eliminating an cryptic error message that would reject orders at times.

Dust values resulting from an account deposit or withdrawal are now filtered out sooner in the process. This eliminates a class of limbo accounts that could result otherwise.

Deposits that include a nested P2WKH input are now properly handled.

An estimation error that would allow a trader to place an order larger than its account balance (which ofc would never be able to be executed) has been fixed.
