Recipe to compare VPP API changes between different releases
Use this recipe to generate the list of API changes between versions of VPP:
- Install the baseline version of VPP packages
export RELEASE=".stable.1801" export UBUNTU="xenial" sudo rm /etc/apt/sources.list.d/99fd.io.list echo "deb [trusted=yes] https://nexus.fd.io/content/repositories/fd.io$RELEASE.ubuntu.$UBUNTU.main/ ./" | sudo tee -a /etc/apt/sources.list.d/99fd.io.list sudo apt-get update sudo apt-get install -y vpp vpp-lib vpp-plugins
- Edit /etc/vpp/startup.conf to enable writing the api table to /tmp/api-table.<release>
api-trace { ## This stanza controls binary API tracing. Unless there is a very strong reason, ## please leave this feature enabled. on ## Additional parameters: ## ## To set the number of binary API trace records in the circular buffer, configure nitems ## ## nitems <nnn> ## ## To save the api message table decode tables, configure a filename. Results in /tmp/<filename> ## Very handy for understanding api message changes between versions, identifying missing ## plugins, and so forth. ## save-api-table api-table.1801 }
- Restart VPP
sudo service vpp restart
- Verify the API table has been saved
ls -l /tmp/api-table.1801
- Uninstall the baseline VPP packages
sudo apt-get remove -y --purge vpp vpp-lib vpp-plugins
- Install the current VPP release
export RELEASE=".stable.1804" export UBUNTU="xenial" sudo rm /etc/apt/sources.list.d/99fd.io.list echo "deb [trusted=yes] https://nexus.fd.io/content/repositories/fd.io$RELEASE.ubuntu.$UBUNTU.main/ ./" | sudo tee -a /etc/apt/sources.list.d/99fd.io.list sudo apt-get update sudo apt-get install -y vpp vpp-lib vpp-plugin
- Dump the API table comparison
vppctl show api dump file /tmp/api-table.1801 compare
- Uninstall the current VPP packages
sudo apt-get remove -y --purge vpp vpp-lib vpp-plugins
