With the introduction of debuginfod ([1]), providing debug symbols to developers has been greatly simplified. Initial support for spawning a debuginfod server is already available as part of poky.
However, this relies on debuginfod scraping the debug packages for their build IDs. This is not only inefficient (as all packages need to be extracted again), but it also does not scale well when covering a large number of builds. To mitigate this, we are currently working on an approach to extract the metadata needed to provide debug symbols as part of the bitbake build. This metadata includes the mapping of the GNU build ID to the package holding the debug symbol. The metadata will be treated as another build artifact and can be consumed by a daemon implementing the debuginfod HTTP API to serve debug symbol file requests from the package feed produced by the bitbake build. Initially, we considered implementing the generation of debug metadata directly as part of emit_pkgdata() in package.bbclass (disabled by default). However, we discarded this idea as introducing a configuration option would increase maintenance effort for a feature that would potentially only be enabled in very few builds. Instead, we opted to extend package.bbclass to expose the minimal information needed to reliably identify debug symbol files, which can then be consumed by a packaging hook. Is this extension something that is viable to be merged? We are considering open-sourcing the other parts needed to implement the setup described above, but as those parts are still in the prototyping phase, it will require some more time.
