Description

When installing a 4.1 agent, it cannot fetch its promises from the 3.1 server, as it looks for rudder-promises-generated file, while rudder_promises_generated is the generated file in 3.1

A little explanation here. While merging initial promises into techniques 4.0, we renamed rudder_promises_generated to rudder-promises-generated (#7927). Just after, we added generation of the old rudder_promises_generated back (#9234), before releasing 4.0.0.

This means that:

  • All released Rudder server generate the rudder_promises_generated file
  • 3.1 agents read the rudder_promises_generated file
  • 4.0/4.1 agents read the rudder-promises-generated

It breaks compatibility between 4.0/4.1 nodes and 3.1 servers (only when upgrading the agents).

This fix will be:

  • Make 4.0/4.1 agents use the rudder_promises_generated file
  • To allow compatibility of released 4.0 nodes (4.0.0 to 4.0.3) with 3.1, will add the generation of rudder-promises-generated to 3.1 servers too
