Eelco Dolstra 12de0466fe Add trace to build errors during import-from-derivation
Example:

error: builder for '/nix/store/9ysqfidhipyzfiy54mh77iqn29j6cpsb-failing.drv' failed with exit code 1;
       last 1 log lines:
       > FAIL
       For full logs, run 'nix log /nix/store/9ysqfidhipyzfiy54mh77iqn29j6cpsb-failing.drv'.

       … while importing '/nix/store/pfp4a4bjh642ylxyipncqs03z6kkgfvy-failing'

Eelco Dolstra c03f41055d Add traces to errors while updating flake lock file
Example:

$ nix build --show-trace
error: unable to download 'https://api.github.com/repos/NixOS/nixpkgs/commits/no-such-branch': HTTP error 422 ('')

       response body:

       {
         "message": "No commit found for SHA: no-such-branch",
         "documentation_url": "https://docs.github.com/rest/reference/repos#get-a-commit"
       }

       … while fetching the input 'github:NixOS/nixpkgs/no-such-branch'

       … while updating the flake input 'nixpkgs'

       … while updating the lock file of flake 'git+file:///home/eelco/Dev/nix'

Eelco Dolstra 8d4268d190 Improve error formatting
Changes:

* The divider lines are gone. These were in practice a bit confusing,
  in particular with --show-trace or --keep-going, since then there
  were multiple lines, suggesting a start/end which wasn't the case.

* Instead, multi-line error messages are now indented to align with
  the prefix (e.g. "error: ").

* The 'description' field is gone since we weren't really using it.

* 'hint' is renamed to 'msg' since it really wasn't a hint.

* The error is now printed *before* the location info.

* The 'name' field is no longer printed since most of the time it
  wasn't very useful since it was just the name of the exception (like
  EvalError). Ideally in the future this would be a unique, easily
  googleable error ID (like rustc).

* "trace:" is now just "…". This assumes error contexts start with
  something like "while doing X".

Example before:

  error: --- AssertionError ---------------------------------------------------------------------------------------- nix
  at: (7:7) in file: /home/eelco/Dev/nixpkgs/pkgs/applications/misc/hello/default.nix

       6|
       7|   x = assert false; 1;
        |       ^
       8|

  assertion 'false' failed
  ----------------------------------------------------- show-trace -----------------------------------------------------
  trace: while evaluating the attribute 'x' of the derivation 'hello-2.10'
  at: (192:11) in file: /home/eelco/Dev/nixpkgs/pkgs/stdenv/generic/make-derivation.nix

     191|         // (lib.optionalAttrs (!(attrs ? name) && attrs ? pname && attrs ? version)) {
     192|           name = "${attrs.pname}-${attrs.version}";
        |           ^
     193|         } // (lib.optionalAttrs (stdenv.hostPlatform != stdenv.buildPlatform && !dontAddHostSuffix && (attrs ? name || (attrs ? pname && attrs ? version)))) {

Example after:

Danila Fedorin 93f1678ec6 Allow Flake inputs to accept boolean and integer attributes
I believe that this makes it possible to do things like
Git inputs with submodules, but it also likely applies
to other input types from libfetchers.

Matthew Bauer d4870462f8 Cast variants fully for libc++10
libc++10 seems to be stricter on what it allows in variant conversion.
I'm not sure what the rules are here, but this is the minimal change
needed to get through the compilation errors.

Replace Value type setters with mk* functions
Move clearValue inside Value

mkInt instead of setInt

mkBool instead of setBool

mkString instead of setString

mkPath instead of setPath

mkNull instead of setNull

mkAttrs instead of setAttrs

mkList instead of setList*

mkBlackhole instead of setBlackhole

mkPrimOp instead of setPrimOp

mkPrimOpApp instead of setPrimOpApp

mkExternal instead of setExternal

mkFloat instead of setFloat

Add note that the static mk* function should be removed eventually

regnat bab1cda0e6 Use the hash modulo in the derivation outputs
Rather than storing the derivation outputs as `drvPath!outputName` internally,
store them as `drvHashModulo!outputName` (or `outputHash!outputName` for
fixed-output derivations).

This makes the storage slightly more opaque, but enables an earlier
cutoff in cases where a fixed-output dependency changes (but keeps the
same output hash) − same as what we already do for input-addressed
derivations.
