Steps for Mapnik Releases

Prepare

Testing

  • Ensure all tests pass (make test)
  • Test Mapnik with INPUT_PLUGINS='' and ensure tests pass for what functionality is available
  • Test with ./configure WARNING_CXXFLAGS="-Wextra" to ensure all problematic warnings are solved or triaged.

Bundled fonts and scons

OPTIONAL: Consider updating Scons-local to latest release: The last SCons update was 2.5.0.

wget http://prdownloads.sourceforge.net/scons/scons-local-2.5.0.zip
rm -rf scons
unzip -o scons-local-*.zip -d scons/
rm scons-local-*.zip

OPTIONAL: Consider updating DeJaVu Fonts: The last version updated was 2.37

cd fonts
git rm -r dejavu-fonts-ttf-
wget http://sourceforge.net/projects/dejavu/files/dejavu/2.37/dejavu-fonts-ttf-2.37.tar.bz2
tar xvf dejavu-fonts-ttf-2.37.tar.bz2
git add dejavu-fonts-ttf-2.37

Make sure to update font paths in demo/c++/rundemo.cpp and benchmark/data/roads.xml

Release candidate

OPTIONAL: If it has been > 3 months since the last official release, consider first promoting a release candidate first:

git tag -a v3.0.0-rc1 -m 'Release Candidate 1 for Mapnik v3.0.0'
git push origin v3.0.0-rc1

Pre-tag updates

make uninstall && ./configure && make
MAPNIK_VERSION=`./utils/mapnik-config/mapnik-config --version`
git commit -a -m "setting up for mapnik v${MAPNIK_VERSION} release [skip ci]" 
git push
  • Update CHANGELOG with the git hash of latest commit using the output of:
git describe # take hash after 'g'
  • Then, push change:
git commit -a -m "update CHANGELOG for mapnik v${MAPNIK_VERSION} release [skip ci]"
git push

Tagging

We use annotated tags below instead of lightweight tags

MAPNIK_VERSION=`mapnik-config --version`
git tag --annotate "v${MAPNIK_VERSION}" -m "tagging v${MAPNIK_VERSION}"
git push origin v${MAPNIK_VERSION}
  • Create and upload clean tarball:

Before running this you'll need:

  • Your mapnik clone needs to be on a tag checkout (either master after tagging or with a tag checked out explicitly) such that git describe gives a clean tag (no trailing -gGITSHA).
  • An environment variable called GITHUB_TOKEN_MAPNIK_PUBLIC_REPO set with a token with public_repo scope.
  • The submodules up to date
make release
  • Test the uploaded tarball:
make test-release

If the make test-release build works then go to https://github.com/mapnik/mapnik/releases, find the latest draft release created by make release and publish it publically.

Post tag updates

  • If there are new styling or datasource options, create a new mapnik-reference entry for the release: https://github.com/mapnik/mapnik-reference

  • Update master branches entries in CHANGELOG from the new release (if relevant, e.g. if you are tagging and releasing a stable release not from the master branch). For example, to sync up master CHANGELOG with v3.0.x branch:

git checkout master
git checkout --patch v3.0.x CHANGELOG.md
git commit -v
git push origin master 

If this was a major release and a stable series is likely, now branch it, for example a 2.1.0 release would warrant an immediate 2.1.x branch for a stable series of bugfix releases.

cd ${MAPNIK_SOURCES}
git branch 2.1.x
git checkout 2.1.x
git push origin 2.1.x
git checkout master

Now bump versions again:

make uninstall && ./configure && make install
MAPNIK_VERSION=`mapnik-config --version`
git ci include/mapnik/version.hpp -m "now working on mapnik v${MAPNIK_VERSION} [skip ci]"
git push

Now also repeat the above for any stable branches created.

Finally, create new github milestones for the newly created future release #s.

And create new launchpad PPA for the target release(s) and series at https://launchpad.net/~mapnik, then add these release PPA's to the list that gets build nightly: https://github.com/mapnik/mapnik-packaging/blob/master/debian-nightlies/nightly-build.sh#L22-40

Update Mapnik.org

  • Update the download page(pages/downloads.html)
  • Write new blog post with updated release links and links to changelog
  • Push python api docs and update docs/index.markdown

Packaging

  1. Submit pull request for homebrew formula
  1. Package binaries for Ubuntu Linux (PPA)
  1. Upload Mac/Win binary packages to the s3 bucket: http://mapnik.s3.amazonaws.com/dist/

TODO - currently do not have bandwidth or set process for this. For Mac: In the past @springmeyer created mac easy installer but just recommending homebrew is better now (since they support binaries/bottles). For Windows: https://github.com/mapbox/windows-builds is used to create SDK's but we've not yet formalized document how these can be used (those they are viable).
