Making a Release of MetPX-sr3c

Release Targets:

  • hpc: intel and powerpc
  • launchpad: whatever platforms it builds for (ARM would be cool.)
  • upload packages to github, which acts as central node for release notifications.
  • See Build for instructions on local building.

Pre-Rrelease QA/Validation

Finalize the changes:

  • update debian/changelog appropriately for the release.
  • in debian/changelog, Set the version on the first line correctly. This version will determine the label on the built packages, regardless of git tag. (perhaps use dch on debian/ubuntu system.)
  • Compile once with -DSR_DEBUG_LOGS to verify that no msg_log calls have errors (compiler will report)
  • make trust_but_verify examine results, which include a valgrind run.

Once that is clean, proceed to the Pre-Release Porting:

Pre-Release Porting

Development is mostly done on new operating systems. The most important platforms for deployment, however, are pretty old.

Prior to doing a full release, should install on all platforms and run tests. on Github, these tests are done by Actions automatically, so one just has to review results for ubuntu 20.04, 22.04, and 24.04. However one must run the tests manually on the following platforms:

for each of:

  • redhat8
  • redhat9
  • ubuntu18

do:

Release Process

To note changes:

  • install package so that it is used for flow tests on at least one platform.
  • find redhat8 (with local disk) and run make test_shim
  • on redhat8, edit Makefile to add -DINTERCEPT_SYSCALL to CFLAGS.
  • find ubuntu18 (with local disk) and run make test_shim.
  • dch, and touch up your points if need be.
  • when ready to release, edit UNRELEASED to an appropriate status, usually unstable.
  • git commit #what you need to commit...
  • git tag <release> -m <release>
  • git push
  • git push origin <release>
  • go to Launchpad, and import source here.
  • go to launchpad, find the recipe and Request Build here.
  • go to an hpc account (on an intel node) * mkdir ~/Sarracenia; cd ~/Sarracenia * git clone https://github.com/MetPX/sarrac metpx-sr3c * edit Makefile to add -DINTERCEPT_SYSCALL to CFLAGS. * cd metpx-sr3c * make rpm_rhel7 * rpm -ivh ~/rpmbuild/RPMS/_platform_/version.rpm (if upgrading, -Uvh)
  • go to a hpc account on a powerpc node * cd Sarracenia/metpx-sr3c * make clean * make rpm_rhel7 * rpm -ivh ~/rpmbuild/RPMS/_platform_/version.rpm

The rpm build targets run rpmbuild which places the packages in a standard tree in the user account: ~/rpmbuild/RPMS/<arch>/..rpm on each arch the rpm will be created in the appropriate directory.
