Making a release of WebKit/GTK+

This document describes the steps toward making a release. To understand release strategy and timing please see ​https://trac.webkit.org/wiki/WebKitGTKStableReleases

1. The last commit before release

• Update the NEWS file using the same format as the previous entry.
  • Identify the commit id of the previous release (NEWS file is normally changed only when releasing, so you could get the commit id of the previous release by looking at NEWS history)
  • Summarize major changes briefly in a style similar to other entries in NEWS.
  • You can use ​gtk-release-notes script.
    • Copy the script to Tools/Scripts and run it giving the commit id of the previous release.
    • It returns a list of bugs fixed since the given revision that might be related to the GTK port and the list fo people who fixed every bug.
  • Take special care to note any additions in the API. The following command will show each patch that has changed a public header file since the given version:

    $ find Source/WebKit/gtk/webkit/ -name "webkit*.h" ! -name '*private.h' | xargs git log -p <commit-id-of-previous-release>.. --
    

• Update configure.ac:
  • The public version is controlled by the lines:

    m4_define([webkit_major_version], [1])
    m4_define([webkit_minor_version], [7])
    m4_define([webkit_micro_version], [5])
    

  • The ​libtool library version is controlled by the line: LIBWEBKITGTK_VERSION=12:0:12
  • The user-agent version should be updated from Source/WebCore/Configurations/Version.xcconfig. It's controlled by the lines:

    m4_define([webkit_user_agent_major_version], [535])
    m4_define([webkit_user_agent_minor_version], [20])
    

2. Run final tests before release

• Run make distcheck with the ​patched version of gnumake.
  • Running "make distcheck" should result in no warnings or errors and show:

    ==================================================
    webkit-X.Y.Z archives ready for distribution:
    webkit-X.Y.Z.tar.gz
    ==================================================
    

• Check that the bots are not horribly broken and run the layout tests locally and see that they are in reasonably good health

3. Make the release

• make distcheck should have created tarball in the build directory. Upload it to petibonum.igalia.com.
• Update the website to add the annoucement and download link
• Tag the release using the command:

  svn cp http://svn.webkit.org/repository/webkit/trunk/  http://svn.webkit.org/repository/webkit/releases/WebKitGTK/webkit-[release version]
  

4. After the release

• Update the API documentation (FIXME: how?)
• Send a message to announce the new release to ​webkit-gtk@lists.webkit.org with CC: ​gnome-announce-list@gnome.org. You can use previous announcements as a template.
• If this release is part of a Gnome release, update the WebKitGTK+ entry of the current modueset in jhbuild repository
• Update the IRC topic message
