Profiling

Prepare profile.data:

zig build -Drelease-small=true && \
    perf record --call-graph=dwarf \
        zig-out/bin/turbonss-unix2db --passwd passwd --group group

Perf interactive:

perf report -i perf.data

Flame graph:

perf script | inferno-collapse-perf | inferno-flamegraph > profile.svg

For v2

These are desired for the next DB format:

• Compress strings with fsst.
• Trim first 4 bytes from the cmph headers.

Dependencies

This project uses git subtrac for managing dependencies. They work just like regular submodules, except all the refs of the submodules are in this repository. Repeat after me: all the submodules are in this repository. So if you have a copy of this repo, dependencies will not disappear.
