“An Overview of the Hash Equivalence & PR Services” by Paul Barker

This talk will give an overview of the Yocto Project’s Hash Equivalence Service (hashserv) and PR Service (prserv). The use cases for these tools will be explored and a demo of each will be given. The new features added to these services since the initial dunfell release in April 2020 will then be discussed, highlighting the read-only modes and the support for connecting to an upstream service. The new features will be demonstrated and the new use cases which these features enable will be presented. Finally, possible future developments will be discussed. This talk will be appropriate for attendees familiar with bitbake but with no prior knowledge of these services. It will also be useful to those with experience using these services who are unfamiliar with the new features added since the dunfell release.
