ReleasingSoftware

From KDE Community Wiki

This page documents the steps to release software packages developed by the KDE community. This guide applies to all software which is not part of a bigger bundle like Frameworks, Plasma and "KDE Applications", which have specific release cycles and release managers.

Sanity Checklist

Stuff your project should have before beta or final release:

Branching

Before you create a release, branch it off of master. The name should be "$MAJOR.$MINOR" or similar, i.e. "1.2". This branch will be called "stable branch" in the text below. Push the branch to the remote repository. 

git checkout -b 1.2
git push --set-upstream origin 1.2

You can also branch after making a tar using releaseme's branchme.rb script

Whenever you make a new stable branch you must e-mail kde-i18n-doc to ask for translations to also be branched and repo-metadata to be updated.

When your product is covered on KDE's CI build.kde.org, once you have created a new branch you need to update the build metadata and trigger some jobs, so build.kde.org can catch up. For that follow this workflow.

Freezing

To prevent regressions early before a release, it is suggested to announce and enforce a "feature-freeze". From this point on, no new features should be introduced to the stable branch.

Before a release, you'll need to give translators a notification about the upcoming new version. Update kde:sysadmin/repo-metadata (read the README.md first), set the "stable i18n branch" to the stable branch. Then write an email about one month before the release or so to the translators at on KDE i18n-doc <[email protected]> . At this point, do not do any changes to translated strings, i.e. consider your branch to be "string-frozen". If you do need a string changed, ask the translators for a string-freeze exception.

Note: The master branch and other feature branches will always be unfrozen, and any kind of strings or features can be changed/added.

Versioning in source code and libraries

When you are ready to do a release, make sure the current HEAD in the stable branch has the correct version string set in its source code as well as the SOVERSION etc., to reflect what you want to release.

A good suggestion is to have something like this in your top-level CMakeLists.txt: 

cmake_policy(SET CMP0048 NEW)
project(kgraphviewer VERSION "2.4.0")

ecm_setup_version(${PROJECT_VERSION}
    VARIABLE_PREFIX KGRAPHVIEWER
    SOVERSION ${PROJECT_VERSION_MAJOR}
    VERSION_HEADER "${CMAKE_CURRENT_BINARY_DIR}/config-kgraphviewer.h"
)

#usage somewhere in cmake for a library:
set_target_properties(kgraphviewerlib PROPERTIES VERSION ${PROJECT_VERSION} SOVERSION ${KGRAPHVIEWER_SOVERSION} OUTPUT_NAME kgraphviewer )

The config-kgraphviewer.h looks like this: 

/* config-kgraphviewer.h.  Generated by cmake from config.-kgraphviewer.h.cmake */

#ifndef CONFIG_KGRAPHVIEWER_H
#define CONFIG_KGRAPHVIEWER_H

#include <kdeversion.h>

#define KGRAPHVIEWER_MAJOR_VERSION @KGRAPHVIEWER_VERSION_MAJOR@
#define KGRAPHVIEWER_MINOR_VERSION @KGRAPHVIEWER_VERSION_MINOR@
#define KGRAPHVIEWER_PATCH_VERSION @KGRAPHVIEWER_VERSION_PATCH@

#define KGRAPHVIEWER_VERSION_STR "@KGRAPHVIEWER_VERSION_MAJOR@.@KGRAPHVIEWER_VERSION_MINOR@.@KGRAPHVIEWER_VERSION_PATCH@"

#define KGRAPHVIEWER_VERSION KDE_MAKE_VERSION(@KGRAPHVIEWER_VERSION_MAJOR@, @KGRAPHVIEWER_VERSION_MINOR@, @KGRAPHVIEWER_VERSION_PATCH@)

#endif // CONFIG_KGRAPHVIEWER_H

Then you can include the generated config-kgraphviewer.h in e.g. your main.cpp and use the KGRAPHVIEWER_VERSION_STR define and similar. You can also install this file (useful for libraries to do feature-detection based on the version number).

NOTE: Don't forget to also increase the version number in master, after you branched off. I.e. as soon as you created a "1.2" branch, ensure master's source code uses a version string such as "1.2.80" which is analogous to 1.3 Alpha 1. "1.2.90" would be 1.3 Beta 1.

Creating a Tarball

The kde:releaseme scripts help with that.

First check you have a working gpg2 install and a key set up which can do the digital signature: 

echo test > test.text; gpg2 --armor --detach-sign -o test.text.sig test.text

If that works create the tar: 

./tarme.rb --version 0.1 --origin stable myapp

This will create myapp-0.1.tar.xz and its digital signature myapp-0.1.tar.xz.sig

--origin can also be trunk. It will use the Git branch set in trunk_kf5 or stable_kf5 in the i18n.json file in your project's repo_metadata

Uploading the Tar

Read readme: ftp://upload.kde.org/README Upload: ftp://upload.kde.org/ 

 $ echo put myapp-0.1.tar.xz | ftp ftp://upload.kde.org/incoming/
 $ echo put myapp-0.1.tar.xz.sig | ftp ftp://upload.kde.org/incoming/

File a sysadmin ticket: https://go.kde.org/u/systickets

Tagging

When you publish your tar you should also push the signed tag to the Git repo. 

./tagme.rb --version 0.1

This uses git running gpg to tag, you may need to set with (see https://help.github.com/articles/telling-git-about-your-gpg-key/) 

 git config --global user.signingkey

test with 

 git init; echo asdf > asdf; git add asdf; git commit -a -m 'commit'; git tag -s -m 'Tagging #{options[:version]}' v123 HEAD

Updating bugzilla

The new version should be added to the list of available versions to the component/product. If you don't have enough permissions, create a sysadmin ticket for that, or ask this a part of the ticket created for the tarballs (see #Uploading_the_Tar)

Announcing the Release

You can create a changelog using releaseme's logme script.

Once the sysadmins moved the tarball, you can announce the release. First, write a detailed blog post on a site that is aggregated on planet.kde.org. Then send a mail to [email protected] and your project's mailing list(s). The mail can be short and link to the longer announcement blog post.

You should include the full fingerprint to the GPG key used to sign the tar and tags in your announce e-mail. (Don't put it on a wiki.) Upload your key to openPGP key servers using gpg2 --send-keys <fingerprint>
