Sergei Zimmerman adbd08399c {libexpr,libcmd}: Make debugger significantly faster ... The underlying issue is that debugger code path was calling PosTable::operator[] in each eval method. This has become incredibly expensive since 5d9fdab3de. While we are it it, I've reworked the code to not use std::shared_ptr where it really isn't necessary. As I've documented in previous commits, this is actually more a workaround for recursive header dependencies now and is only necessary in `error.hh` code. Some ad-hoc benchmarking: After this commit: ``` Benchmark 1: nix eval nixpkgs#hello --impure --ignore-try --no-eval-cache --debugger Time (mean ± σ): 784.2 ms ± 7.1 ms [User: 561.4 ms, System: 147.7 ms] Range (min … max): 773.5 ms … 792.6 ms 10 runs ``` On master 3604c7c51: ``` Benchmark 1: nix eval nixpkgs#hello --impure --ignore-try --no-eval-cache --debugger Time (mean ± σ): 22.914 s ± 0.178 s [User: 18.524 s, System: 4.151 s] Range (min … max): 22.738 s … 23.290 s 10 runs ```		2025-03-13 16:24:30 +00:00
