Store path length limit?

[dhess]

What's the technical reason for the 211-character store path length limit?

nix/src/libstore/path.cc

Line 9 in 7c90552

if (name.size() > 211)

I'm using npmlock2nix to package a React app, and I'm running into this limitation:

error: store path 'w0p04i8klrmla412sxk0539dpx45c408-qpl7imy79n9sd9a2h6s7armj9vqaal70-rk74xqfkqgc282lxhym3vwd9ww35iv7n-9sp1q8q5p3r6h2qm4g74ycp1f7b44zv7-9ikdajp8imc685n5vmiib3f9lny2ygz0-0xnc8c7z7rzxp1hf0vfdjwhhvwd19q3b-helper-builder-binary-assignment-operator-visitor-7.14.5.tgz' has a name longer than 211 characters

The 211-character limit is motivated in this commit 693e68e.

Wow, I'm surprised ext4's limit is so short.

In any case, I will close this as it seems unlikely to change. I'll take it up with the npmlock2nix maintainers.
