debuginfod-rs

An extremely fast debuginfod server, written in Rust.

[2023-12-13T08:35:11.001Z INFO  debuginfod_rs] walking 173017 RPM files (477.8 GB)
[2023-12-13T08:35:12.389Z INFO  debuginfod_rs] parsing took: 2.09 s (228.8 GB/s)
  • ⚡️ ~30x faster than the elfutils' debuginfod (only RPM metadata are parsed)
  • 🧵 multithreaded parser and web server
  • 🦋 in-memory database (~200MiB per 1TB of the indexed RPM files)
  • 📦 RPM-based only (openSUSE and Fedora/RHEL packages supported)
  • 🌐 full debuginfod Web API supported
  • 🗜 commonly used compressions supported (bzip2, gzip, xz, zstd)

Implementation details

The indexer benefits from symlinks created by rpmbuild which link each ELF executable (and shared library) and it's corresponding build-id path. Each web request first identifies an RPM file with a build-id and the corresponding ELF (or source) file is extracted on demand. Grouping of the foo-debuginfo, foo-debugsource and foo packages happens based on the source RPM file (present in the RPM file metadata).

The indexing speed heavily depends on the disk speed, where one can get up to ~100 GB/s on a modern AMD CPU (for the cached IO).

Known limitations

  • missing AsyncRead support for RPM container visitor (content is read to memory in a web response)
  • indexer does not implement elfutils' heuristics for header file requests where the file is part of a build-id, but it's actually present in a different RPM package (e.g. header files of the devel sub-packages of a library)
  • missing disk cache
  • missing support for other containers like .deb
