For every file "lib/debug/.build-id/<build-id>.debug" in every store path ending in -debug in a release, this command creates an S3 key "debuginfo/<build-id>" specifying the location of the NAR that contains the debug info file for that build ID. Thus, https://cache.nixos.org/debuginfo allows debug info files to be looked up by build ID. This allows debug info files to be fetched automatically by dwarffs [1]. One minor issue is that in theory, multiple store paths could provide debug info files for a particular build ID. So then when we garbage collect a store path from the binary cache, we migth invalidate a debug info link even though there are non-GC'ed store paths that provide the file. Ah well. I could have used HTTP redirects, but they're kind of a pain to configure with S3. [1] https://github.com/edolstra/dwarffs |
