This is a collection of Lix plugins that showcase how to write one for
various usecases.
The first is a mTLS store plugin that enable mTLS cache URIs
(`https+mtls://`).
We enable meson build system support for this plugin but we are not
going to distribute it in the official packaging of Lix, we will
repackage each relevant plugin downstream in Nixpkgs.
These plugins have *NO* guarantee support, they are provided as useful
references and are possibly production-ready if your usecase is simple
enough.
Reference: https://github.com/NixOS/nix/pull/13030 (this change has
resemblances but our APIs are different, the tests harness is mostly
from CppNix).

With this patch, and this file I called `log.py`:
#!/usr/bin/env nix-shell
#!nix-shell -i python3 -p python3 --pure
import sys
from pprint import pprint
stack = []
timestack = []
for line in open(sys.argv[1]):
components = line.strip().split(" ", 2)
if components[0] != "function-trace":
continue
direction = components[1]
components = components[2].rsplit(" ", 2)
loc = components[0]
_at = components[1]
time = int(components[2])
if direction == "entered":
stack.append(loc)
timestack.append(time)
elif direction == "exited":
dur = time - timestack.pop()
vst = ";".join(stack)
print(f"{vst} {dur}")
stack.pop()
and:
nix-instantiate --trace-function-calls -vvvv ../nixpkgs/pkgs/top-level/release.nix -A unstable > log.matthewbauer 2>&1
./log.py ./log.matthewbauer > log.matthewbauer.folded
flamegraph.pl --title matthewbauer-post-pr log.matthewbauer.folded > log.matthewbauer.folded.svg
I can make flame graphs like: http://gsc.io/log.matthewbauer.folded.svg

Includes test cases around function call failures and tryEval. Uses
RAII so the finish is always called at the end of the function.
