2019-11-22	getEnv(): Return std::optional	Eelco Dolstra
	This allows distinguishing between an empty value and no value.
2018-08-30	nix upgrade-nix: Handle .nix-profile being a link to .../profiles/per-user/...	Eelco Dolstra
	Also some cosmetic improvements.
2018-08-30	nix upgrade-nix: Improve error message if 'nix' is not in a profile	Eelco Dolstra
	E.g. $ nix upgrade-nix error: directory '/home/eelco/Dev/nix/inst/bin' does not appear to be part of a Nix profile instead of $ nix upgrade-nix error: '/home/eelco/Dev/nix/inst' is not a symlink
2018-08-30	Merge branch 'nix-upgrade-profile' of https://github.com/LnL7/nix	Eelco Dolstra

2018-08-30	Add simple test for nix upgrade-nix	Eelco Dolstra

2018-08-25	upgrade-nix: resolve profile symlinks	Daiderd Jordan
	The profile present in PATH is not necessarily the actual profile location. User profiles are generally added as $HOME/.nix-profile in which case the indirect profile link needs to be resolved first. /home/user/.nix-profile -> /nix/var/nix/profiles/per-user/user/profile /nix/var/nix/profiles/per-user/user/profile -> profile-15-link /nix/var/nix/profiles/per-user/user/profile-14-link -> /nix/store/hyi4kkjh3bwi2z3wfljrkfymz9904h62-user-environment /nix/var/nix/profiles/per-user/user/profile-15-link -> /nix/store/6njpl3qvihz46vj911pwx7hfcvwhifl9-user-environment To upgrade nix here we want /nix/var/nix/profiles/per-user/user/profile-16-link instead of /home/user/.nix-profile-1-link. The latter is not a gcroot and would be garbage collected, resulting in a broken profile. Fixes #2175

2018-06-12	Move EvalState from the stack to the heap	Eelco Dolstra
	EvalState contains a few counters (e.g. nrValues) that increase quickly enough that they end up being interpreted as pointers by the garbage collector. Moving it to the heap makes them invisible to the garbage collector. This reduces the max RSS doing 100 evaluations of nixos.tests.firefox.x86_64-linux.drvPath from 455 MiB to 292 MiB. Note: ideally, allocations would be much further up in the 64-bit address space to reduce the odds of an integer being misinterpreted as a pointer. Maybe we can use some linker magic to move the .bss segment to a higher address.
2018-05-30	Move evaluator-specific settings out of libstore	Eelco Dolstra

2018-01-31	Add 'nix upgrade-nix' command	Eelco Dolstra
	This command upgrades Nix to the latest stable version by installing a store path obtained from https://github.com/NixOS/nixpkgs/raw/master/nixos/modules/installer/tools/nix-fallback-paths.nix which is the same store path that the installer at https://nixos.org/nix/install.sh uses. The upgrade fails if Nix is not installed in a profile (e.g. on NixOS, or when installed outside of the Nix store).
