USDT probes are statically defined trace points that have nearly zero disabled-probe effect, i.e. we can put them in hot paths. The use case for these is both similar and dissimilar to Rust tracing: We still need better logging and a better structured rust-tracing looking thing, but probes allow for quite easy programmable interactive tracing in production, which we also care a lot about. This CL comes with a perfunctory trace point in libstore/file-transfer.cc for reading data out of the curl buffer. This was mostly thrown in there so that I could see what the buffer sizes of this were, and maybe be able to instrument the perf of the curl usages in Lix in the future.

Lix
Lix is an implementation of Nix, a powerful package management system for Linux and other Unix systems that makes package management reliable and reproducible.

Installation
On Linux and macOS the easiest way to install Lix is to run the following shell command (as a user other than root):
$ curl -sSf -L https://install.lix.systems/lix | sh -s -- install
For systems that already have a Nix implementation installed, such as NixOS systems, read our install page
Building And Developing
See our Hacking guide in our manual for instruction on how to set up a development environment and build Lix from source.
