brpc apache release guide step by step
Overview: divided into the following steps
- Preparation: including generating the key required for signature, creating github release branch and tag, modifying the version file, etc
- Publish software package: including making source tarball, signing, uploading to the designated location and verifying
- Vote: including voting in mail group
- Release announcement: including updating brpc website, sending announcement emails, posting WeChat official account announcements, merging the release branche into the master branch
1. Install GPG
Download the installation package from GnuPG official website. The commands of GnuPG version 1.x and version 2.x are slightly different. The following instructions take the
GnuPG-2.3.1 version (OSX) as an example.
After the installation is complete, execute the following command to check the version number.
2. Create key
After the installation is complete, execute the following command to create a key.
Complete the key creation according to the prompts. Note that the mailbox should use the Apache email address, and the
Real Name can use Apache ID or GitHub ID:
gpg (GnuPG) 2.3.1; Copyright (C) 2021 Free Software Foundation, Inc. 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 (2) DSA and Elgamal (3) DSA (sign only) (4) RSA (sign only) (9) ECC (sign and encrypt) *default* (10) ECC (sign only) (14) Existing key from card Your selection? 1 RSA keys may be between 1024 and 4096 bits long. What keysize do you want? (3072) 4096 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 Key does not expire at all Is this correct? (y/N) y GnuPG needs to construct a user ID to identify your key. Real name: LorinLee Email address: firstname.lastname@example.org Comment: lorinlee's key You selected this USER-ID: "LorinLee (lorinlee's key) <email@example.com>" Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O You need a Passphrase to protect your secret key. # Input password 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. gpg: key 92E18A11B6585834 marked as ultimately trusted gpg: revocation certificate stored as '/Users/lilei/.gnupg/openpgp-revocs.d/C30F211F071894258497F46392E18A11B6585834.rev' public and secret key created and signed. pub rsa4096 2021-10-17 [SC] C30F211F071894258497F46392E18A11B6585834 uid LorinLee (lorinlee's key) <firstname.lastname@example.org> sub rsa4096 2021-10-17 [E]
3. Check the generated key
gpg: checking the trustdb gpg: marginals needed: 3 completes needed: 1 trust model: pgp gpg: depth: 0 valid: 2 signed: 0 trust: 0-, 0q, 0n, 0m, 0f, 2u /Users/lilei/.gnupg/pubring.kbx ---------------------------------- pub rsa4096 2021-10-17 [SC] C30F211F071894258497F46392E18A11B6585834 uid [ultimate] LorinLee (lorinlee's key) <email@example.com> sub rsa4096 2021-10-17 [E]
C30F211F071894258497F46392E18A11B6585834 is the public key.
4. Publish the public key to server
Execute the following command:
gpg --keyserver hkp://pgp.mit.edu --send-key C30F211F071894258497F46392E18A11B6585834
5. Generate fingerprint and upload to apache user profile
Since the public key server has no verifying mechanism, anyone can upload the public key in your name, so there is no way to guarantee the reliability of the public key on the server. Usually, you can publish a public key fingerprint on your website and let others check the downloaded public key.
Execute the following command to view the fingerprint.
gpg --fingerprint lorinlee # user id
/Users/lilei/.gnupg/pubring.kbx ---------------------------------- pub rsa4096 2021-10-17 [SC] C30F 211F 0718 9425 8497 F463 92E1 8A11 B658 5834 uid [ultimate] LorinLee (lorinlee's key) <firstname.lastname@example.org> sub rsa4096 2021-10-17 [E]
Paste the above fingerprint
C30F 211F 0718 9425 8497 F463 92E1 8A11 B658 5834 into the
OpenPGP Public Key Primary Fingerprint: field of your Apache user information on https://id.apache.org.
Prepare release package
1. Create release branch
If you are releasing a new MINOR version, like
1.0.0, you need to create a new branch
release-1.0 from master.
If you are releasing a new PATCH version from existing MINOR version, like
1.0.1, you only need to modify the existing
release-1.0 branch and add the content to be released.
The code modification during the release process are performed on the release branch (such as
release-1.0). After the release is complete, please merge the release branch back into the master branch.
2. Update version in source code
Update RELEASE_VERSION file
RELEASE_VERSION file in the project root directory, update the version number, and submit it to the code repository. For example, the
1.0.0 version of the file is:
Update CMakeLists.txt file
CMakeLists.txt file in the project root directory, update the version number, and submit it to the code repository. For example:
Update /package/rpm/brpc.spec file
/package/rpm/brpc.spec file in the project root directory, update the version number, and submit it to the code repository. For example:
3. Create releasing tag
push the release branch to tag, For example:
git clone -b release-1.0 email@example.com:apache/brpc.git ~/brpc cd ~/brpc git tag -a 1.0.0 -m "release 1.0.0" git push origin --tags
4. Create releasing package
git archive --format=tar 1.0.0 --prefix=apache-brpc-1.0.0-incubating-src/ | gzip > apache-brpc-1.0.0-incubating-src.tar.gz
5. Generate GPG signature
gpg -u firstname.lastname@example.org --armor --output apache-brpc-1.0.0-incubating-src.tar.gz.asc --detach-sign apache-brpc-1.0.0-incubating-src.tar.gz gpg --verify apache-brpc-1.0.0-incubating-src.tar.gz.asc apache-brpc-1.0.0-incubating-src.tar.gz
6. Generate SHA512 sum
sha512sum apache-brpc-1.0.0-incubating-src.tar.gz > apache-brpc-1.0.0-incubating-src.tar.gz.sha512 sha512sum --check apache-brpc-1.0.0-incubating-src.tar.gz.sha512
Publish to Apache SVN repository
1. checkout dist/dev/brpc directory
If there is no local working directory, create a local working directory first. Clone the Apache SVN repository, username needs to use your own Apache LDAP username:
mkdir -p ~/brpc_svn/dev/ cd ~/brpc_svn/dev/ svn --username=lorinlee co https://dist.apache.org/repos/dist/dev/incubator/brpc/ cd ~/brpc_svn/dev/brpc
2. Add GPG public key
A new release manager must add the key into KEYS file for the first time.
(gpg --list-sigs lorinlee && gpg -a --export lorinlee) >> KEYS
3. Add the releasing package to SVN directory
mkdir -p ~/brpc_svn/dev/brpc/1.0.0 cd ~/brpc_svn/dev/brpc/1.0.0 cp ~/brpc/apache-brpc-1.0.0-incubating-src.tar.gz ~/brpc_svn/dev/brpc/1.0.0 cp ~/brpc/apache-brpc-1.0.0-incubating-src.tar.gz.asc ~/brpc_svn/dev/brpc/1.0.0 cp ~/brpc/apache-brpc-1.0.0-incubating-src.tar.gz.sha512 ~/brpc_svn/dev/brpc/1.0.0
4. Submit SVN
Return to the parent directory and use the Apache LDAP account to submit SVN
cd ~/brpc_svn/dev/brpc svn add * svn --username=lorinlee commit -m "release 1.0.0"
1. Verify SHA512 sum
sha512sum --check apache-brpc-1.0.0-incubating-src.tar.gz.sha512
2. Verify GPG signature
First import the publisher’s public key. Import KEYS from the svn repository to the local. (The person who releases the version does not need to import it again. The person who verify needs to import it.)
curl https://dist.apache.org/repos/dist/dev/incubator/brpc/KEYS >> KEYS gpg --import KEYS
Trust the signature of publisher, execute the following command using the publisher’s user name
gpg --edit-key lorinlee
gpg (GnuPG) 2.3.1; Copyright (C) 2021 Free Software Foundation, Inc. This is free software: you are free to change and redistribute it. There is NO WARRANTY, to the extent permitted by law. Secret key is available. gpg> trust 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 gpg> save
Then verify the GPG signature:
gpg --verify apache-brpc-1.0.0-incubating-src.tar.gz.asc apache-brpc-1.0.0-incubating-src.tar.gz
3. Check release content
1. Compare the difference of between the source code package and github tag
curl -Lo tag-1.0.0.tar.gz https://github.com/apache/brpc/archive/refs/tags/1.0.0.tar.gz tar xvzf tag-1.0.0.tar.gz tar xvzf apache-brpc-1.0.0-incubating-src.tar.gz diff -r brpc-1.0.0 apache-brpc-1.0.0-incubating-src
2. Check file content
- Check whether the source code package contains unnecessary files, which makes the tarball too large
- LICENSE and NOTICE files exist
- The year in the NOTICE file is correct
- Only text files exist, no binary files exist
- All files have an ASF license at the beginning
- Source code can be compiled correctly, and the unit test can pass
- Check whether there are redundant files or folders, such as empty folders
- Check for third-party dependency licenses:
- Third party dependency license compatibility
- All licenses of third-party dependency are declared in the LICENSE file
- The complete version of the dependency license is in the license directory
- If third-party dependency have the Apache license and have NOTICE files, these NOTICE files also need to be added to the releasing NOTICE file
