Verify a release candidate

To verify the release, the following checklist can be used to reference:

  • Download links are valid.
  • Checksums and PGP signatures are valid.
  • Source code artifacts have correct names matching the current release.
  • LICENSE and NOTICE files are correct for the repository.
  • All files have license headers if necessary.
  • Building is OK.
note

It is NOT necessary to run all checks to cast a vote for a release candidate.

However, you should clearly state which checks you did. The release manager needs to ensure that each check was done.

Download the release package to be verified to the local environment​

Use the following command to download all artifacts, replace "${release_version}-${rc_version}" with the version ID of the version to be released:

svn co https://dist.apache.org/repos/dist/dev/kvrocks/${release_version}-${rc_version}/

Verify signature and hash​

Start the verification process, which includes but is not limited to the following content and verification methods.

Check if the release package is complete​

The package to release must check:

  • Whether to include the source code package
  • Whether to include the signature of the source code package
  • Whether to include the sha512 of the source code package
  • Check the binary package (if include), also check the contents listed above

Verify signature and hash​

GnuPG is recommended, which can install by yum install gnupg, apt-get install gnupg or brew install gnupg.

First, import public key:

curl https://downloads.apache.org/kvrocks/KEYS > KEYS # Download KEYS
gpg --import KEYS # Import KEYS to local

Then, trust the public key by entering gpg --edit-key <KEY-used-in-this-version> and finishing interactively:

Please decide how far you trust this user to correctly verify other users' keys
(by looking at passports, checking fingerprints from different sources, etc.)

  1 = I don't know or won't say
  2 = I do NOT trust
  3 = I trust marginally
  4 = I trust fully
  5 = I trust ultimately
  m = back to the main menu

Your decision? 5
Do you really want to set this key to ultimate trust? (y/N) y

Now, check signature and hash:

  1. Save below shell codes to file release-verify.sh
#!/usr/bin/env bash

YELLOW="\033[37;1m"
GREEN="\033[32;1m"
ENDCOLOR="\033[0m"

if [ "$#" -ne 1 ]; then
  echo "Usage: $0 {YOUR RELEASE TAR FILE}" >&2
  exit 1
fi

PKG=$1

if [ ! -f "$PKG" ]; then
    echo "File '$PKG' does not exist."
    exit 1
fi

#gpg --armor --output "$PKG.asc" --detach-sig $PKG
gpg --verify "$PKG.asc" $PKG

if [ $? -eq 0 ]
then
    printf $GREEN"Success to verify the gpg sign"$ENDCOLOR"\n"
else
    printf $YELLOW"Failed to verify the gpg sign"$ENDCOLOR"\n"
fi

#shasum -a 512 $PKG > "$PKG.sha512"
shasum -a 512 -c "$PKG.sha512"

if [ $? -eq 0 ]
then
    printf $GREEN"Success to verify the checksum"$ENDCOLOR"\n"
else
    printf $YELLOW"Failed to verify the checksum"$ENDCOLOR"\n"
fi
  1. verify the sign and checksum
./release-verify.sh apache-kvrocks-${release_version}-src.tar.gz

You will see the following output on success:

gpg: Signature made 五 11/11 01:04:23 2022 CST

Check the file content of the source package​

Unzip apache-kvrocks-${release_version}-src.tar.gz and check the follows:

  • LICENSE and NOTICE files are correct for the repository.
  • All files have ASF license headers if necessary.
  • Building is OK.
