cec23f5dda ExprOpHasAttr,ExprSelect,stripIndentation,binds,formals: delete losts objects
We are looking for *$ because it indicate that it was constructed with a new but
not release. De-referencing shallow copy so deleting as whole might create
dangling pointer that's why we move it so we delete a empty containers + the
nice perf boost.

5978ceb271 Fix building with GCC 9
Nixpkgs on aarch64-linux is currently stuck on GCC 9
(https://github.com/NixOS/nixpkgs/issues/208412) and using gcc11Stdenv
doesn't work either.

So use c++2a instead of c++20 for now. Unfortunately this means we
can't use some C++20 features for now (like std::span).

Merge pull request #5588 from tweag/balsoft/xdg
Follow XDG Base Directory standard
2023-02-10 18:05:50 +01:00

A setting to follow XDG Base Directory standard
XDG Base Directory is a standard for locations for storing various
files. Nix has a few files which seem to fit in the standard, but
currently use a custom location directly in the user's ~, polluting
it:

- ~/.nix-profile
- ~/.nix-defexpr
- ~/.nix-channels

This commit adds a config option (use-xdg-base-directories) to follow
the XDG spec and instead use the following locations:

- $XDG_STATE_HOME/nix/profile
- $XDG_STATE_HOME/nix/defexpr
- $XDG_STATE_HOME/nix/channels

If $XDG_STATE_HOME is not set, it is assumed to be ~/.local/state.

This is a nice idea that @roberth requested. If we could factor our a
generic `std::variant` impl as a follow-up it would be even better!

general.

getDefaultNixPath: actually respect {restrict,pure}-eval
Previously, getDefaultNixPath was called too early: at initialisation
time, before CLI and config have been processed, when `restrictEval` and
`pureEval` both have their default value `false`. Call it when
initialising the EvalState instead, and use `setDefault`.

153ee460c5 primop: add readFileType, optimize readDir
Allows checking directory entry type of a single file/directory.

This was added to optimize the use of `builtins.readDir` on some
filesystems and operating systems which cannot detect this information
using POSIX's `readdir`.

Previously `builtins.readDir` would eagerly use system calls to lookup
these filetypes using other interfaces; this change makes these
operations lazy in the attribute values for each file with application
of `builtins.readFileType`.

0afdf4084c Fix #7655
We had some local variables left over from the older (more
complicated) implementation of this function. They should all be unused,
but one wasn't by mistake.

Delete them all, and replace the one that was still in use as intended.

ce2f91d356 Split OutputsSpec and ExtendedOutputsSpec, use the former more
`DerivedPath::Built` and `DerivationGoal` were previously using a
regular set with the convention that the empty set means all outputs.
But it is easy to forget about this rule when processing those sets.
Using `OutputSpec` forces us to get it right.

5576d5e987 Parse string context elements properly
Prior to this change, we had a bunch of ad-hoc string manipulation code
scattered around. This made it hard to figure out what data model for
string contexts is.

Now, we still store string contexts most of the time as encoded strings
--- I was wary of the performance implications of changing that --- but
whenever we parse them we do so only through the
`NixStringContextElem::parse` method, which handles all cases. This
creates a data type that is very similar to `DerivedPath` but:

 - Represents the funky `=<drvpath>` case as properly distinct from the
   others.

 - Only encodes a single output, no wildcards and no set, for the
   "built" case.

(I would like to deprecate `=<path>`, after which we are in spitting
distance of `DerivedPath` and could maybe get away with fewer types, but
that is another topic for another day.)

da64f026dd Make clear that StorePathWithOutputs is a deprecated type
- Add a comment

- Put `OutputsSpec` in a different header (First part of #6815)

- Make a few stray uses of it in new code use `DerivedPath` instead.
