Release steps#

Below, a list of steps that should be done in order to publish a new release is given. All necessary commits which have no ticket of their own may refer to #563.

Merge phase#

Major changes to the SUMO trunk should end about two weeks before the release date. This refers especially to merges of project branches into the trunk. It is also a good idea to inform the developers of dependent software (Veins, VSimRTI, flow etc.) at this stage. - send out mail to sumo-dev informing about the upcoming release so that 'contributed'-authors can check their stuff for compatibility

Freeze phase (Release day - 7)#

  • check the sources
    • compile, try to remove warnings and commit the patches
    • run tools/build_config/checkStyle.py and commit changed files
    • check the calendar to update copyright statements
    • check whether the TraCI version needs to be incremented and rebuild TraCI constants in python (tools/traci/rebuildConstants.py)
    • check whether the network version needs to be incremented and update the value in NWFrame::MAJOR_VERSION. netconvert tests need to be updated afterwards.
    • update author information
  • check the regular tests
    • put special attention to the tests which serve as examples, see tests/examples.txt!
    • Win64 and gcc4_64 should have no failing tests, the other platforms are less important
    • If there are failing tests, which are not flagged as known bugs, save them after careful checking or open a ticket and assign a known bug.
    • recheck/rebuild the test networks (if necessary due to netconvert changes)
    • check for orphaned tests by running tools/devel/orphaned_tests.py tests and patch testsuites to add them back in
    • check the tests again
  • check the documentation
    • update the ChangeLog
    • generate options documentation and xsd schemata for configuration files using tools/build_config/rebuildConfigDocsAndXsd.py
  • check the internal tests (same procedure as above), especially the (to be) published scenarios
  • GitHub
    • add new milestone if necessary
    • check all remaining tickets and assign them to later milestones or to persons.
  • scenarios (optional)
    • prepare scenarios for release if the previous version does not run with the current release or significant changes were made to the scenarios
  • update submodules by running git submodule update --remote and committing the changes if necessary

The trunk is now frozen. All commits which do not refer to an open ticket for the upcoming release need to be made to a separate branch. The freeze phase should not last longer than one week. The goal is to fix all scenarios and have all failing tests fixed, which are not assigned to a later milestone.

Release day - 1#

All scenarios should be fixed by now.

  • start and save a new version draft in Zenodo (using the sumo@dlr.de user), in order to reserve a DOI. Don't Publish it yet, and don't upload a file to it!
    • update the version doi in CITATION.cff and in the README badge to this new reserved one
  • patch the version information using tools/build_config/updateReleaseInfo.py 0.13.7 and double check changes
    • in src/config.h.cmake, also the HAVE_VERSION_H macro should be disabled
    • in CMakeLists.txt
    • in mkdocs.yml in the extra: section at the end to update the download links
    • in sumo.metainfo.xml for correct flatpak info
    • in CITATION.cff
    • commit the changes
  • recheck whether submodules changed by doing git submodule update --remote and committing the changes after careful inspection
  • check the documentation
    • update the ChangeLog again and include version and release date
  • If it is the first release of the year, create a new Eclipse release at https://projects.eclipse.org/projects/automotive.sumo (after login there should be a "Create Release" button)
    • add an IP Log to the release
    • send an email to the PMC at automotive-pmc@eclipse.org asking for review (include links to the release and the IP log)
  • check presence of RPMs on https://build.opensuse.org/package/show/science:dlr/sumo_nightly
  • add a new version tag
> git tag -a v0_13_7 -m "tagging release 0.13.7, refs #563"
> git push --tags

Release day#

The nightly build should have generated all releasable packages. If not, delay the release. (The complete documentation, tests and source distribution build can be achieved via "make dist".) The following things need to be there:

If everything is fine:

  • make a new folder in S:\Releases
  • make new sumo.dlr.de-release
    • copy the folder from S:\Releases to the releases dir scp -r /media/S/Releases/x.y.z delphi@ts-sim-front-ba.intra.dlr.de:docs/releases
  • update the eclipse.dev/sumo website
    • modify the version number (Version) and the DOI number (DOI) in config.yaml in the Default Parameters section
    • generate the static files cd src && hugo -d ../ and commit them
  • make new sourceforge-release
    • make a new release within the sumo package (named "version x.y.z")
    • add files to the release
    • change default download attributes
  • finish the Zenodo version draft, by uploading the release .tar.gz source, and publishing it
  • create a new entry in elib
  • update files at the opensuse build service
  • update the ubuntu ppa (see https://askubuntu.com/questions/642632/how-to-bump-the-version-of-a-package-available-in-another-users-ppa)
    • this assumes you have the devscripts package as well as all sumo dependencies installed
      • if you try this on Windows Linux Subsystem you will also need to do sudo update-alternatives --set fakeroot /usr/bin/fakeroot-tcp
    • unzip the special source release sumo_1.21.0+dfsg1.orig.tar.gz
    • copy the debian dir one level up
    • modify the changelog, using dch (enter an email address which has write access to the ppa and a valid gpg key)
    • run dpkg-buildpackage -S in the sumo dir and dput -f ppa:sumo/stable sumo_1.21.0+dfsg1_source.changes one level up
  • update the flatpak (update version number and commit hash)
  • start a pull request against winget
  • update the Homebrew Formula
  • do a remote login to the M1 Mac and upload the wheels to PyPI using twine upload clangMacOS_M1/sumo/dist_native/* clangMacOS_M1/sumo/wheelhouse/*
  • scenarios (optional)
  • inform the users about the new release
  • close the milestone (retargeting open tickets needs to be done manually for now)
  • add the latest version to the "software version identifier" statement in Wikidata (this will update the Wikipedia articles about SUMO), making sure to select the latest version as "preferred rank" and setting the previous one to "normal rank".

After-release cleanup#

The trunk is now open for changes again.

  • re-enable HAVE_VERSION_H in src/config.h.cmake
  • rename version to "git" in CMakeLists.txt
  • insert a new empty "Git Main" section at the top of the ChangeLog
  • commit changes
  • drink your favorite beverage
