Elfshaker: GiB – 100 MiB, with 1s access time
Author here. No architecture specific processing currently. Most of the magic happens in zstandard (hat tip to this amazing project).
Please see our new applicability section which explains the result in a bit more detail:
https://github.com/elfshaker/elfshaker/blob/1bedd4eacd3ddd83...
In manyclangs (which uses elfshaker for storage) we arrange that the object code has stable addresses when you do insertions/deletions, which means you don't need such a filter. But today I learned about such filters, so thanks for sharing your question!
One of the authors here, thanks for the feedback. We've tried to improve it here: https://github.com/elfshaker/elfshaker/pull/59
Same here. There is a usage guide, which helped a tiny bit: https://github.com/elfshaker/elfshaker/blob/main/docs/users/...
Honestly, I sort of looked at it for conventional backup strategy...as in, i wonder if it could work as a replacement for tar-zipping up a directory, etc. But, not sure if the use cases is appropriate.
We've just added an applicability section, which explains a bit more what we do. We don't have any ELF specific heuristics.
https://github.com/elfshaker/elfshaker#applicability
In summary, for manyclangs, we compile with -ffunction-sections and -fdata-sections, and store the resulting object files. These are fairly robust to insertions and deletions, since the addresses are section relative, so the damage of any addresses changing is contained within the sections. A somewhat surprising thing is that this works well enough when building many revisions of clang/llvm -- as you go from commit to commit, many commits have bit identical object files, even though the build system often wants to rebuild them because some input has changed.
elfshaker packs use a heuristic of sorting all unique objects by size, before concatenating them and storing them with zstandard. This gives us an amortized cost-per-commit of something like 40kiB after compression with zstandard.
