Eelco DolstraandGitHub a7fb7d3cde Merge pull request #2303 from volth/patch-4 
parser.y: fix assoc of -> and < > <= >=
 2018-07-23 11:38:15 +02:00
volthandGitHub deaa6e9a34 parser.y: right-associativity of -> 2018-07-23 07:28:48 +00:00
volthandGitHub 85fe4a819c parser.y: fix assoc of -> and < > <= >= 
The parser allowed senseless `a > b > c` but disallowed `a -> b -> c` which seems valid
It might be a typo

volthandGitHub e2b114cfe1 prim_foldlStrict: call forceValue() before value is copied 
forceValue() were called after a value is copied effectively forcing only one of the copies keeping another copy not evaluated.
This resulted in its evaluation of the same lazy value more than once (the number of hits is not big though)

Eelco Dolstra 455d1f01d0 Don't scan for roots in dynamic libraries 
This reduces the risk of object liveness misdetection. For example,
Glibc has an internal variable "mp_" that often points to a Boehm
object, keeping it alive unnecessarily. Since we don't store any
actual roots in global variables, we can just disable data segment
scanning.

With this, the max RSS doing 100 evaluations of
nixos.tests.firefox.x86_64-linux.drvPath went from 718 MiB to 455 MiB.

Ben Gamari 7f560b81ea json-to-value: Use strtol instead of strtoi 
NixInt is long, so strtoi is too restrictive.

 2018-05-24 15:00:39 +02:00
Eelco Dolstra 4bb8741b98 Make Env self-describing 
If the Env denotes a 'with', then values[0] may be an Expr* cast to a
Value*. For code that generically traverses Values/Envs, it's useful
to know this.

Eelco Dolstra 9fd7cf98db Memoise checkSourcePath()

Eelco Dolstra f3c85f9eb3 Revert "Throw a specific error for incomplete parse errors." 
This reverts commit 6498adb002. We don't
actually use IncompleteParseError in 'nix repl'.

Eelco Dolstra a91c4ca01f In restricted eval mode, allow access to the closure of store paths 
E.g. this makes

  nix eval --restrict-eval -I /nix/store/foo '(builtins.readFile "/nix/store/foo/symlink/bla")'

(where /nix/store/foo/symlink is a symlink to another path in the
closure of /nix/store/foo) succeed.

This fixes a regression in Hydra compared to Nix 1.x (where there were
no restrictions at all on access to the Nix store).

Tuomas Tynkkynen af86132e1a libexpr: Make unsafeGetAttrPos not crash on noPos 
Currently e.g. `builtins.unsafeGetAttrPos "abort" builtins` will
eventually segfault because pos->file is an unset Symbol.
