Apache Publishing Guide

This article takes the release of 1.0.3 Apache version as an example. If it is a non-Apache version, please refer to the detailed information https://incubator.apache.org/guides/releasemanagement.html

Understand the content and process of Apache's release. Source Release is the focus of Apache’s attention and is also a required content for release; Binary Release is optional. Please refer to the following link to find more ASF release guidelines:

Both apache's maven and SVN repositories use GPG signatures to verify the legitimacy of material files

1 Tool preparation

:::caution Note Required when this publisher is publishing for the first time :::

Mainly include the preparation of the signature tool GnuPG, Maven repository certification

1.1 Install GPG

(Take the Window system as an example, if the git client has been installed, gpg may already exist, and there is no need to install it again)

Download the binary installation package (GnuPG binary releases) at GnuPG official website. The latest version is Gpg4win-3.1.16 2021-06-11 After downloading, please complete the installation operation first Note: The commands of GnuPG 1.x version and 2.x version are slightly different. The following description takes 2.2.28 as an example After installation, the gpg command is added to the system environment variables and is available

#Check the version, it should be 2.x
$ gpg --version

1.2. Generate key with gpg

Note the following points:

The mailbox used should be apache mailbox
It is best to use pinyin or English for the name, otherwise garbled characters will appear

According to the prompt, generate the key

$ gpg --full-gen-key
gpg (GnuPG) 2.2.28; Copyright (C) 2021 g10 Code GmbH
This is free software: you are free to change and redistribute it.
There is NO WARRANTY, to the extent permitted by law.

Please select what kind of key you want:
   (1) RSA and RSA (default)
   (2) DSA and Elgamal
   (3) DSA (sign only)
   (4) RSA (sign only)
  (14) Existing key from card
Your selection? 1 #here enter 1
RSA keys may be between 1024 and 4096 bits long.
What keysize do you want? (3072) 4096 #Enter 4096 here
Requested keysize is 4096 bits
Please specify how long the key should be valid.
         0 = key does not expire
      <n> = key expires in n days
      <n>w = key expires in n weeks
      <n>m = key expires in n months
      <n>y = key expires in n years
Key is valid for? (0) 0 #here enter 0
Key does not expire at all
Is this correct? (y/N) y #Enter y here

GnuPG needs to construct a user ID to identify your key.

Real name: mingXiao #Enter Pinying or English name here
Email address: xiaoming@apache.org #Enter the email address of apache here
Comment: for apache release create at 20211110 #Enter some comments here, can be empty
You selected this USER-ID:
    "mingXiao (for apache release create at 20211110) <xiaoming@apache.org>"

Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O #Enter O here
We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.

# At this time, a dialog box will pop up, asking you to enter the key for this gpg. you need to remember that it will be used in subsequent steps.
┌─────────────────────────────────────────────────────┐
│ Please enter this passphrase to protect your new key│
│                                                     │
│ Passphrase: _______ no less than 8 digits _________ │
│ Repeat: ___________________________________________ │
│ <OK> <Cancel>                                       │
└─────────────────────────────────────────────────────┘
#After entering the secret key, a certain random action needs to be performed to generate encrypted prime numbers. After creation, the following information will be output
gpg: key 1AE82584584EE68E marked as ultimately trusted
gpg: revocation certificate stored as'C:/Users/xxx/AppData/Roaming/gnupg/openpgp-revocs.d\E7A9B12D1AC2D8CF857AF5851AE82584584EE68E.rev'
public and secret key created and signed.

pub rsa4096 2021-11-10 [SC]
      E7A9B12D1AC2D8CF857AF5851AE82584584EE68E
uid mingXiao (for apache release create at 20211110) <xiaoming@apache.org>
sub rsa4096 2021-11-10 [E]

1.3. Upload the generated key to the public server

$ gpg --keyid-format SHORT --list-keys
pub rsa4096/584EE68E 2021-11-10 [SC] #584EE68E is the key id
      E7A9B12D1AC2D8CF857AF5851AE82584584EE68E
uid [ultimate] mingXiao (for apache release create at 20211110) <xiaoming@apache.org>
sub rsa4096/399AA54F 2021-11-10 [E]

# Send public key to keyserver via key id
$ gpg --keyserver keyserver.ubuntu.com --send-key 584EE68E
# Among them, keyserver.ubuntu.com is the selected keyserver, it is recommended to use this, because the Apache Nexus verification uses this keyserver

1.4. Check whether the key is created successfully

Verify whether it is synchronized to the public network. It takes about a minute to find out. If it is not successful, you can upload and retry several times

# method one
$ gpg --keyserver keyserver.ubuntu.com --recv-keys 584EE68E #584EE68E is the corresponding key id

#Results are as follows
gpg: key 1AE82584584EE68E: "mingXiao (for apache release create at 20211110) <xiaoming@apache.org>" not changed
gpg: Total number processed: 1
gpg: unchanged: 1

# method two
Go directly to https://keyserver.ubuntu.com/ and enter the username mingXiao to search the query results

1.5 Add the gpg public key

This step requires the use of SVN, please download and install the SVN client first, Apache uses svn to host the project’s published content

Uniffle DEV branch https://dist.apache.org/repos/dist/dev/incubator/uniffle
Uniffle Release branch https://dist.apache.org/repos/dist/release/incubator/uniffle

1.5.1 Add public key to KEYS in dev branch

Used to release RC version

$ mkdir -p uniffle_svn/dev
$ cd uniffle_svn/dev

$ svn co https://dist.apache.org/repos/dist/dev/incubator/uniffle
# This step is relatively slow, and all versions will be copied. If the network is broken, use svn cleanup to delete the lock and re-execute it, and the upload will be resumed.
$ cd uniffle_svn/dev/uniffle

# Append the KEY you generated to the file KEYS, it is best to check if it is correct after appending
$ (gpg --list-sigs YOUR_NAME@apache.org && gpg --export --armor YOUR_NAME@apache.org) >> KEYS
# If there is a KEYS file before, it is not needed
$ svn add KEYS
#Submit to SVN
$ svn ci -m "add gpg key for YOUR_NAME"

1.5.2 Add public key to KEYS in release branch

Used to release the official version


$ mkdir -p uniffle_svn/release
$ cd uniffle_svn/release

$ svn co https://dist.apache.org/repos/dist/release/incubator/uniffle
# This step is relatively slow, and all versions will be copied. If the network is broken, use svn cleanup to delete the lock and re-execute it, and the upload will be resumed.

$ cd uniffle
# Append the KEY you generated to the file KEYS, it is best to check if it is correct after appending
$ (gpg --list-sigs YOUR_NAME@apache.org && gpg --export --armor YOUR_NAME@apache.org) >> KEYS
# If there is a KEYS file before, it is not needed
$ svn add KEYS
#Submit to SVN
$ svn ci -m "add gpg key for YOUR_NAME"

2 Publish staging artifacts

2.1 Set environment variables

export RELEASE_RC_NO=${RC NO, eg: 1, 2 ,3};
export ASF_USERNAME=${YOUR ASF USERNAME};
export ASF_PASSWORD=${YOUR ASF PASSWORD};
export RELEASE_VERSION=${release version, eg:0.8.0}

2.2 Create a tag

We should prepare a new branch, modify and ensure the version of pom, and add a tag

git checkout branch-${RELEASE_VERSION}
git tag v${RELEASE_VERSION}-rc${RELEASE_RC_NO}
git push origin v${RELEASE_VERSION}-rc${RELEASE_RC_NO}

2.3 Publish the Apache SVN repository

$ ./release/publish_to_svn.sh

2.4 Publishing maven artifacts

2.4.1 Upload the artifacts

$  ./release/publish_maven_artifacts.sh

2.4.2 Stage the release for a vote

Now you must close the staging repository(https://repository.apache.org/#stagingRepositories) to indicate to Nexus that the build is done and to make the artifacts available. Follow the steps in Closing the Staged Repository, later in this document. This will allow your community to vote on the staged artifacts. Refer: https://central.sonatype.org/publish/release/#locate-and-examine-your-staging-repository
