go-github-release

HOWTO implement a feature complete release software flow over github.

Aka, s/a software factory/ma petite entreprise/.

Made with the power of go, built with unix philsophy, it provides concerns-centric lightweight tools that can benefit to any project of any language, Issue #15

maintain a changelog, with changelog
maintain a README, with emd
bump your package, with gump
create github release, with gh-api-cli
produce debian packages, with go-bin-deb
produce rpm packages, with go-bin-rpm
produce windows installers, with go-msi
produce chocolatey repository on bintray
produce debian repository over bintray
produce rpm repository over bintray

head first

You might want to setup, or prepare, the required softwares on your computer.

a github account

Not everything you will read does require a github account, although, this guide uses it to demonstrate a real world example, thus, get one if you did not already signed up.

a bintray account

Specifically for the deployment of your artifacts on a repository, it has oss support, you can sign up with your github account.

windows users

Install chocolatey https://chocolatey.org/install
Add this repository

$ choco source add -n=mh-cbon -s="https://api.bintray.com/nuget/mh-cbon/choco"

Install a software

$ choco install <software> -y
$ refreshenv

debian users

Add this repository

$ sudo add-apt-repository 'deb https://dl.bintray.com/mh-cbon/deb unstable main'

Update the metadata

$ sudo apt-get -qq update

Install a software

$ sudo apt-get install --allow-unauthenticated <sofware>

rpm users

Add this repository

$ sudo curl -s -L https://bintray.com/mh-cbon/rpm/rpm > /etc/yum.repos.d/mh-cbon.repo

Install a software

$ sudo dnf install <sofware> -y

a dummy project

To illustrate this guide, let s create a dummy application, written in go, might be any language.

$ mkdir $GOPATH/src/github.com/USER/dummy
$ cd $GOPATH/src/github.com/USER/dummy
$ git init

$ cat <<EOT > src/README.md
# dummy

Says hello when invoked on the command line

## Usage

`` `sh
hello - 0.0.1

Say hello.
`` `
EOT

$ git add README.md
$ git commit README.md -m "init: add README"

$ cat <<EOT > src/main.go
// Package hello is a command line program to say hello.
package main

import (
	"fmt"
)

func main() {
	fmt.Println("Hello")
}
EOT

$ git add main.go
$ git commit main.go -m "init: add main"

$ go run main.go
hello

# create teh repo in your github account
$ xdg-open https://github.com/new

# push
$ git remote add origin [email protected]:USER/dummy.git
$ git push --set-upstream origin master

At that point you do have a,

a git repository with a first commit
a git remote pointing to your github repository
a github repository

maintaining a changelog

wikipedia

A changelog is a log or record of all or all notable changes made to a project. The project is often a website or software project, and the changelog usually includes records of changes such as bug fixes, new features, etc. Some open source projects include a changelog as one of the top level files in their distribution.

A changelog has historically included all changes made to a project. The "Keep a CHANGELOG" site instead advocates that a changelog not include all changes, but that it should instead contain "a curated, chronologically ordered list of notable changes for each version of a project" and should not be a "dump" of a git log "because this helps nobody".[1]

If you read the wikipedia link, you may have noticed that a CHANGELOG is not defined by a file format, instead, it is a practice to communicate to the community of users.

Now the problem is presents this way for us: in the wonderful world of software factory, multiple tool, from multiple different vendors, with multiple different opinions, about this or that /wahtever/, all desperately invite or enforce you to produce a changelog file in their own incompatible format, in the best case. In the worst case it is simply ignored.

To solve that situation, changelog was written:

it provides one format to rule them all
it integrates seemlessly into a software factory process
it simplifies and helps the developer to maintain the CHANGELOG file

In practice

For a new repository the CHANGELOG file must be initialized,

$ changelog init
changelog file created

$ ls -al change.log
-rw-rw-r-- ... change.log

# This is a pending change log.
$ cat change.log
UNRELEASED

  * init: add main
  * init: add README

  - USER <email>

-- USER <email>; Tue, 21 Jun 2016 11:41:13 +0200

# Add and commit this file to your repository
$ git add change.log
$ git commit change.log -m "init: changelog"

changelog generates a change.log file, for each tags (or versions) existing in the repository, it creates a new version with its associated commits in chronological order.

The UNRELEASED version you are seeing now, is a intermediary version containing the changes for the upcoming release.

When a new version is about to be released, changes for the next version needs to be gathered, run

$ changelog prepare
changelog file updated

$ cat change.log
UNRELEASED

  * init: changelog
  * init: add main
  * init: add README

  - USER <email>

-- USER <email>; Tue, 21 Jun 2016 11:41:13 +0200

This prepare state is here to invite to manually update, fix, re-arrange the content of the changelog before it is finalized.

It is the good moment to check your commits, identify the useless commit messages, group them around a functionnality or feature.

In this example we have various different commit messages with more or less the same meaning, also the content of those commit are truely useless to everybody, for clarity, lets rewrite it in this way

UNRELEASED

  * Initial release

  - USER <email>

-- USER <email>; Tue, 21 Jun 2016 11:41:13 +0200

Finally, let s manually create the first version before we review the steps to do that via automation,

# promote UNRELEASED changes to 0.0.1
$ changelog finalize --version=0.0.1
changelog file updated

# Verify the content
$ cat change.log
0.0.1

  * Initial release

  - USER <email>

-- USER <email>; Tue, 21 Jun 2016 11:41:13 +0200

# export the change.log file to a markdwon compatible format
$ changelog md -o CHANGELOG.md --vars='{"name":"dummy"}'

$ cat CHANGELOG.md
# Changelog - dummy

maintain a README

https://en.wikipedia.org/wiki/README

A README file contains information about other files in a directory or archive of computer software. A form of documentation, it is usually a simple plain text file called READ.ME, README.TXT, README.md (for a text file using markdown markup), README.1ST – or simply README.

The contents typically include one or more of the following:

- Configuration instructions
- Installation instructions
- Operating instructions
- A file manifest (list of files included)
- Copyright and licensing information
- Contact information for the distributor or programmer
- Known bugs[2]
- Troubleshooting[2]
- Credits and acknowledgments
- A changelog (usually for programmers)
- A news section (usually for users)

Many activities to perform to maintain a README,

Some of those such as installation instructions, contact or licensing are usually a one time setup that does not change a lot.

Other sections such as file manifest, usage, code example are likely to change as the software evolves, this is where maintenance help is needed.

To help with those concerns emd provides an engine on top of the go template package, it includes features specifically designed to help with this maintenance task.

Check the detailed documentation at emd

In practice

Create a new file README.e.md which will contain the template to generate the final README.md,

$ cat <<EOT > src/README.e.md
# {{.Name}}

{{pkgdoc}}

# {{toc 4}}

# Example

#### $ {{exec "go" "run" "main.go" | color "sh"}}
EOT

# commit this template to your repo for future update of the README
$ git add README.e.md
$ git commit main.go -m "init: add README"

# generate/commit the final README file
$ emd gen -in README.e.md -out README.md
$ git add README.md
$ git commit main.go -m "init: generate README"

That's it! The new README.md file contains,

  # hello

  Package hello is a command line program to say hello.

  # TOC
  - [Example](#example)

  # Example

  #### $ go run main.go
  ` ``sh
  Hello
  ` ``

Now it s easier to maintain the README file.

bump a package

stackoverflow

Increment the version number to a new, unique value.

In semver semantics version are expressed such as <major>.<minor>.<patch>-<prerelease>+<meta>

version numbers and the way they change convey meaning about the underlying code and what has been modified from one version to the next.

In practice changing a version number involves many side operations,

the CHANGELOG needs to be updated,
the tag needs to be created,
the remote needs to be synced,
the README might need a refresh
linters needs to run
tests needs to run
and many more

gump was written to let you automate as many tasks as possible around that central task of version bump:

bump using verbs rather than numerical values
run pre/post operations to the version bumping

It does not compete with well-known tools like make, those two softwares are similar, but different, a make user should keep using make and load it into gump.

In practice

gump provides a very limited set of features,

$ gump -h
Gump - Bump your package

Usage:
  gump prerelease [-b|--beta] [-a|--alpha] [-d|--dry] [-m <message>]
  gump patch [-d|--dry] [-m <message>]
  gump minor [-d|--dry] [-m <message>]
  gump major [-d|--dry] [-m <message>]

That s all, 4 verbs, 4 flags.

However, it provides the ability to declare a file .version.sh to define various hooks related to the action of version bumping:

PREBUMP=
  echo "before bumping, any verb"
PREPATCH=
  echo "before bumping to patch"
PREMINOR=
  echo "before bumping to minor"
PREMAJOR=
  echo "before bumping to major"

PREVERSION=
  echo "before bumping the version, any verb"
POSTVERSION=
  echo "after version bumped, any verb"

POSTMAJOR=
  echo "after version bumped to major"
POSTMINOR=
  echo "after version bumped to minor"
POSTPATCH=
  echo "after version bumped to patch"
POSTBUMP=
  echo "after bumping, any verb"

Using that file, it is now possible to define tasks to run before / after a specific kind of bump verb,

$ cat <<EOT > .version.sh
# PREBUMP runs for all kinds of bump
PREBUMP=
  # it is usefull to make sure local is in sync with remote
  git fetch --tags origin master
  git pull origin master

# PREVERSION runs for any kinds of bump, it the last pre-hook
PREVERSION=
  # use it to declare tasks that should run for any kind of bump
  go vet ./...
  go fmt ./...
  go run main.go # alike tests when you don t have tests
  # finalize the changelog
  changelog finalize --version !newversion!
  git commit change.log -m "changelog: !newversion!"
  # update the README
  emd gen -in README.e.md > README.md
  git commit README.md -m "README: !newversion!"
  # generate a markdwon version of your changelog
  changelog md -o CHANGELOG.md --vars='{"name":"dummy"}'
  git commit CHANGELOG.md -m "changelog.md: !newversion!"

# POSTVERSION runs for any kind of bumps
POSTVERSION=
  # use it to sync your local to the remote
  git push
  git push --tags
  # create a github release
  gh-api-cli create-release -n release -o USER -r dummy \
   --ver !newversion!  --draft !isprerelease! \
   -c "changelog ghrelease --version !newversion!"
EOT

$ git add .version.sh
$ git commit .version.sh -m "init: bump script"

Those are the steps to bump the project,

# gather your last changes
$ changelog prepare
changelog file updated

$ cat change.log
UNRELEASED

  * init: release automation

  - USER <email>

-- USER <email>; Tue, 21 Jun 2016 11:42:13 +0200

-- USER <email>; Tue, 21 Jun 2016 11:41:13 +0200

# update the content of the UNRELEASED version
# ....

# invoke the bumper with the next version
$ gump patch
Created new tag 0.0.2
...

That's it, the project version 0.0.1 is patch-bumped to 0.0.2

$ cat CHANGELOG.md

notes about .version.sh

It worth to note that the syntax is cross-platform, stackoverflow.

gump takes care to handle '\' EOL appropriately.

Before bumping anything, it is absolutely necessary to sync the local with your remote.

PREBUMP=
  git fetch --tags origin master
  git pull origin master

For every version to bump, its good to ensure the linters/tests/compile all passes.

PREVERSION=
  go vet ./...
  go fmt ./...
  go run main.go

use POSTVERSION to implement the setup / creation of artifacts from your computer without the help of a cloud ci. In this example, it creates a new github release in the repo github.com/USER/dummy, set it drafted if the version is a prerelease such as beta|alpha, attach an extract of the version changes to the new release.

POSTVERSION=
  gh-api-cli create-release -n release -o USER -r dummy \
   --ver !newversion!  --draft !isprerelease! \
   -c "changelog ghrelease --version !newversion!"

github releases

To work with github apis, this guide uses gh-api-cli a cross-platform command line utility

For a detailed documentation visit.

tokens

For that current guide, gh-api-cli helps to deal with github personal access tokens.

Those tokens are useful to realize api calls that requires authentification.

Later you will learn how to inject those tokens into your CI files such travis, appveyor, you name it.

Lets create a new token with the name release,

$ gh-api-cli add-auth -n release -r repo
.. provides the details

The token is stored in a json file located at ~/gh-auths.json.

You can retrieve token values with

$ TOKEN=`gh-api-cli get-auth -n release`
$ echo $TOKEN

protip

Sometimes it is useful to be able to upload assets by your own,

gh-api-cli upload-release-asset -t <gh token> -g <glob> -o <gh repo user> -r <gh repo name> --ver <version>
# or
gh-api-cli upload-release-asset -n <token name> -g <glob> -o <gh repo user> -r <gh repo name> --ver <version>

various other useful cross-platform tools

Find various small cross-platform tools to use into your scripts,

file pattern matching philea
commit files with convenience commit
improve output 666
ignore failures never-fail
run commands in parallel cct
rm with pattern matching rm-glob
create zip/tar-gz archives archive

specifically for go

fail the formating changed go-fmt-fail
one-liner go build build-them-all

packaging

This section will guide you to create platforms specific packages.

To build platforms specific packages, the corresponding OS must be run,

You can use a vagrant box, a docker image, this guide will use travis and appveyor

working with travis

Connect your github account to travis and enable your repository

xdg-open http://travis-ci.org/ # link the github account
xdg-open https://travis-ci.org/profile/USER # enable the repository

To encrypt a token, you can use an online encryptor, or the travis cli, read the doc anyway https://docs.travis-ci.com/user/encryption-keys/

To install the travis client,

$ gem install travis -v 1.8.2 --no-rdoc --no-ri

protip

travis encrypt --add -r USER/dummy GH_TOKEN=`gh-api-cli get-auth -n <auth name>`

working with appveyor

Connect your github account to appveyor and enable your repository

xdg-open https://ci.appveyor.com/
xdg-open https://ci.appveyor.com/projects/new

To encrypt a token, go to

xdg-open https://ci.appveyor.com/tools/encrypt

notes: unlike travis, appveyor let you re use the same encrypted variable in every project you enable.

For advanced setup, you might find helpful to have a local vagrant running windows, please check this link.

working with bintray

signup to bintray

xdg-open https://bintray.com/signup/oss

Open your bintray acccount, signin, then create 4 repositories:

msi
choco
deb
rpm

token

find your token at https://bintray.com/profile/edit > API KEY

protip

Delete an asset on bintray in a cross platform way

never-fail curl -X "DELETE" -u<USER>:<BTKEY> https://api.bintray.com/content/<USER>/choco/<file path>

Make sure to set this environment variable in your CI JFROG_CLI_OFFER_CONFIG=false

debian

debian wiki

A Debian package is a collection of files that allow for applications or libraries to be distributed via the Debian package management system. The aim of packaging is to allow the automation of installing, upgrading, configuring, and removing computer programs for Debian in a consistent manner.

debian binary package

A Debian Package is a file that ends in .deb and contains software for your Debian system. A .deb is also known as a binary package. This means that the program inside the package is ready to run on your system.

The guide will demonstrate the creation of debian binary package.

While this is not the holy grail of debian packaging, go-bin-deb will be help you to,

distribute your application to non developers
install / remove your application via the standard package manager
setup services, icons, folders etc

In practice

Create a deb.json file to describe the package content

$ cat <<EOT > deb.json
{
  "name": "dummy",
  "maintainer": "USER <email>",
  "description": "Say hello",
  "changelog-cmd": "changelog debian --vars='{\"name\":\"!name!\"}'",
  "homepage": "http://github.com/USER/!name!",
  "files": [
    {
      "from": "build/!arch!/!name!",
      "to": "/usr/bin",
      "base" : "build/!arch!/",
      "fperm": "0755"
    }
  ],
  "copyrights": [
    {
      "files": "*",
      "copyright": "2016 USER <email>",
      "license": "MIT",
      "file": "LICENSE"
    }
  ]
}
EOT

IE:

create a debian package with the name dummy
the license is MIT its content is available in the file LICENSE
there is only one file located at build/!arch!/dummy to copy to /usr/bin
the change list is generated with the command changelog debian --vars='{\"name\":\"dummy\"}'

Tokens you can find in the json are documented here

Detailed documentation is available at here

Using travis

Create a .travis.yml file. It will contains the instructions to

build the debian package
upload the artifacts to a github release
upload the artifacts to a bintray

Thats it!

To trigger a travis build that generates the packages, make a new version.

$ git add deb.json .travis.yml
$ git commit -m "packaging: add debian package support"

$ changelog prepare

RPM

rpm

The RPM Package Manager (RPM) is a powerful command line driven package management system capable of installing, uninstalling, verifying, querying, and updating computer software packages. Each software package consists of an archive of files along with information about the package like its version, a description, and the like. There is also a library API, permitting advanced developers to manage such transactions from programming languages such as C or Python.

Much like go-bin-deb go-bin-rpm will help to generate a package for rpm based systems.

In practice

Create an rpm.json file to describe the package content

$ cat <<EOT > rpm.json
{
  "name": "dummy",
  "summary": "Say hello",
  "description": "A command line to say hello",
  "changelog-cmd": "changelog rpm",
  "license": "LICENSE",
  "url": "https://github.com/USER/!name!",
  "files": [
    {
      "from": "build/!arch!/!name!",
      "to": "%{_bindir}/",
      "base": "build/!arch!/",
      "type": ""
    }
  ]
}
EOT

create an rpm package with the name dummy
the license is MIT its content is available in the file LICENSE
there is only one file located at build/!arch!/dummy to copy to %{_bindir} from the base path build/!arch!/ (it will create the file /usr/bin/dummy)
the change list is generated with the command changelog rpm

Using travis

Update the .travis.yml file to generate rpm packages,

windows

wikipedia

The Windows Installer XML Toolset (WiX, pronounced "wicks"), is a free software toolset that builds Windows Installer packages from XML code. It consists of a command-line environment that developers may integrate into their build processes to build MSI and MSM packages.

wix documentation

In the same spirit as go-bin-deb and go-bin-rpm, go-msi will help you to produce msi package and nuget packages.

nuget packages are useful to integrate with chocolatey

In practice

Create a file wix.json to describe the package content

$ cat <<EOT > wix.json
{
  "product": "dummy",
  "company": "USER",
  "license": "LICENSE",
  "upgrade-code": "",
  "files": {
    "guid": "",
    "items": [
      "dummy.exe"
    ]
  },
  "env": {
    "guid": "",
    "vars": [
      {
        "name": "PATH",
        "value": "[INSTALLDIR]",
        "permanent": "no",
        "system": "no",
        "action": "set",
        "part": "last"
      }
    ]
  }
}
EOT

create an msi installer containing dummy.exe
copy the file at ~~ C:\program files\dummy
add C:\program files\dummy to the PATH

Then setup GUIDs value within the wix.json file with the help of go-msi, run

$ go-msi set-guid
file updated

notes: guid s should be set once at beginning and not updated later.

Using appveyor

To perform the build of the package, create an appveyor.yml file.

Thats it!

To trigger an appveyor build that generates the packages, make a new version.

$ git add wix.json appveyor.yml
$ git commit -m "packaging: add msi package support"

$ changelog prepare
changelog file updated

$ changelog show
<check then improve the change list>

$ gump patch
.. commands output
Created new tag 0.0.5
.. commands output

Within minutes both appveyor and travis will create the packages and put all of them into the github release page

github release page

Sometimes you want to distribute only build artifacts and not the whole packages and repostiory.

$ .version.sh

POSTVERSION=
  # clean up
  666 rm-glob -r build/
  666 rm-glob -r assets/
  # build program for many OS-ARCH
  666 build-them-all build main.go -o "build/&os-&arch/&pkg" --ldflags "-X main.VERSION=!newversion!"
  # create a ZIP archive for windows
  philea -s -S -p "build/windows*/*" "666 archive create -f -o=assets/%dname.zip -C=build/%dname/ ."
  # create a TGZ archive for !windows
  philea -s -S -e windows*/** -p "build/*/**" "666 archive create -f -o=assets/%dname.tar.gz -C=build/%dname/ ."
  # create a github release
  666 gh-api-cli create-release -n release -o USER -r dummy --ver !newversion! -c "changelog ghrelease --version !newversion!" --draft !isprerelease!
  # upload assets to the release
  666 gh-api-cli upload-release-asset -n release --glob "assets/*" -o USER -r dummy --ver !newversion!
  # clean up
  666 rm-glob -r build/
  666 rm-glob -r assets/

distribution

You are all set now!

You can now add those instructions to your README,

windows

 - choco source add -n=<USER> -s="https://api.bintray.com/nuget/<USER>/choco"
 - choco install dummy -y
 - refreshenv

debian

 - sudo add-apt-repository 'deb https://dl.bintray.com/<USER>/deb unstable main'
 - sudo apt-get -qq update
 - sudo apt-get install --allow-unauthenticated -y dummy

redhat

- sudo curl -s -L https://bintray.com/<USER>/rpm/rpm > /etc/yum.repos.d/<USER>.repo
- sudo dnf install go-bin-rpm changelog rpm-build -y

protip

emd has helpers for that matter, see here.

Oops, it failed :s

For various reasons the build might fail, on bump or during the ci, in such case you are left with a project in a loosy state.

For example, you might end up with,

a git tag
a gh release
failed ci did not produce packages

The simplest solution is to simply remove traces of that broken release, fix the bump pipeline, then bump again.

$ gump patch
...
failure
....
$ VERSION=x.x.x
# revert, fix then restart
$ git tag -d $VERSION
$ git push origin :$VERSION
$ gh-api-cli rm-release -n <auth name> -o USER -r dummy --ver $VERSION
# rename last release to UNRELEASED
$ changelog rename
# apply fixes to the pipeline
$ gump patch # again

Errors reference

Reports your difficulties to this repository to help to build this index of errors reference.

The end !!

This is it, with some tools and cloud services, the releases of the software are kept up to date with a two step commands,

$ changelog prepare
$ gump <patch|minor|major>

Enjoy the reusable and modular system those tools provide you to feet your own vision, contribute and report your success.

~~ Happy coding!
