Eelco Dolstra 2bd0fcc966 Use libnix as a prefix for all Nix libraries 
In particular "libutil" was always a problem because it collides with
Glibc's libutil.  Even if we install into $(libdir)/nix, the linker
sometimes got confused (e.g. if a program links against libstore but
not libutil, then ld would report undefined symbols in libstore
because it was looking at Glibc's libutil).

Eelco Dolstra c1f3a1a89b Disallow undefined symbols in dynamic libraries by default 
This encourages that each library declares its own dependencies
properly.

Eelco Dolstra 5a1114ecdb Drop the dependency on libgc in libmain 
Instead, libexpr now depends on libgc.  This means commands like
nix-store that don't do any evaluation no longer require libgc.

Eelco Dolstra 90b5e69284 Support quoted attribute names in -A 
This is requires if you have attribute names with dots in them.  So
you can now say:

  $ nix-instantiate '<nixos>' -A 'config.systemd.units."postgresql.service".text' --eval-only

Fixes #151.

Eelco Dolstra a478e8a7bb Remove nix-setuid-helper 
AFAIK, nobody uses it, it's not maintained, and it has no tests.
 2013-11-14 11:57:37 +01:00
Eelco Dolstra 89e6781cc5 Make function calls show up in stack traces again 
Note that adding --show-trace prevents functions calls from being
tail-recursive, so an expression that evaluates without --show-trace
may fail with a stack overflow if --show-trace is given.

Eelco Dolstra c897bac549 Make function calls tail-recursive 2013-11-12 11:32:23 +00:00
Eelco Dolstra 273322c773 Make ifs and asserts tail-recursive 
The local Value object prevented g++ from making a tail call.  Not
clear why.  In any case, not using a temporary makes g++ do the tail
call.

Eelco Dolstra dec2f19502 Fix a segfault in genericClosure 
It kept temporary data in STL containers that were not scanned by
Boehm GC, so Nix programs using genericClosure could randomly crash if
the garbage collector kicked in at a bad time.

Also make it a bit more efficient by copying points to values rather
than values.

Eelco Dolstra ea6bf0c21f Slightly optimize listToAttrs 2013-10-28 07:34:44 +01:00
Eelco Dolstra 5bc41d78ff Rename "attribute sets" to "sets" 
We don't have any other kind of sets so calling them attribute sets is
unnecessarily verbose.

Eelco Dolstra 69befd33a9 Remove unnecessary call to forceStringNoCtx 2013-10-24 03:08:34 +02:00
Eelco Dolstra 05d02f798f Add a typeOf primop 
We already have some primops for determining the type of a value, such
as isString, but they're incomplete: for instance, there is no isPath.
Rather than adding more isBla functions, the generic typeOf function
returns a string representing the type of the argument (e.g. "int").

Eelco Dolstra fe95650487 Memoize evalFile() lookups under both the original and resolved name 
Previously we only used the resolved name, causing repeated resolution
(e.g. /dir to /dir/default.nix).

Eelco Dolstra c086183843 For auto roots, show the intermediate link 
I.e. "nix-store -q --roots" will now show (for example)

rather than

  /nix/var/nix/gcroots/auto/53222qsppi12s2hkap8dm2lg8xhhyk6v

Eelco Dolstra 792fd51f41 Fold two stack trace messages in derivations 
Combined with the previous changes, stack traces involving derivations
are now much less verbose, since something like

  while evaluating the builtin function `getAttr':
  while evaluating the builtin function `derivationStrict':
  while instantiating the derivation named `gtk+-2.24.20' at `/home/eelco/Dev/nixpkgs/pkgs/development/libraries/gtk+/2.x.nix:11:3':
  while evaluating the derivation attribute `propagatedNativeBuildInputs' at `/home/eelco/Dev/nixpkgs/pkgs/stdenv/generic/default.nix:78:17':
  while evaluating the attribute `outPath' at `/nix/store/212ngf4ph63mp6p1np2bapkfikpakfv7-nix-1.6/share/nix/corepkgs/derivation.nix:18:9':
  ...

now reads

  while evaluating the attribute `propagatedNativeBuildInputs' of the derivation `gtk+-2.24.20' at `/home/eelco/Dev/nixpkgs/pkgs/development/libraries/gtk+/2.x.nix:11:3':
  ...
 2013-10-17 11:57:25 +02:00
Eelco Dolstra f440558acc Don't show <nix/derivation.nix> in stack traces 
Messages like

  while evaluating the attribute `outPath' at `/nix/store/212ngf4ph63mp6p1np2bapkfikpakfv7-nix-1.6/share/nix/corepkgs/derivation.nix:18:9':

are redundant, because Nix already shows that it's evaluating a derivation:

  while instantiating the derivation named `firefox-24.0' at `/home/eelco/Dev/nixpkgs/pkgs/applications/networking/browsers/firefox/default.nix:131:5':
  while evaluating the derivation attribute `nativeBuildInputs' at `/home/eelco/Dev/nixpkgs/pkgs/stdenv/generic/default.nix:76:17':

Eelco Dolstra b8034e5581 Ensure proper type checking/coercion of "${expr}" 
Now we only rewrite "${expr}" to expr if expr is a string literal.

Eelco Dolstra d6a7aa8f48 Revert the behaviour of antiquoted paths to pre-Nix 1.6 
Commit 159e621d1a accidentally changed
the behaviour of antiquoted paths, e.g.

  "${/foo}/bar"

used to evaluate to "/nix/store/<hash>-foo/bar" (where /foo gets
copied to the store), but in Nix 1.6 it evaluates to "/foo/bar".  This
is inconsistent, since

  " ${/foo}/bar"

evaluates to " /nix/store/<hash>-foo/bar".  So revert to the old
behaviour.

Eelco Dolstra a737f51fd9 Retry all SQLite operations 
To deal with SQLITE_PROTOCOL, we also need to retry read-only
operations.

Eelco Dolstra ff02f5336c Fix a race in registerFailedPath() 
Registering the path as failed can fail if another process does the
same thing after the call to hasPathFailed().  This is extremely
unlikely though.

Eelco Dolstra 4bd5282573 Convenience macros for retrying a SQLite transaction 2013-10-16 14:46:35 +02:00
Eelco Dolstra bce14d0f61 Don't wrap read-only queries in a transaction 
There is no risk of getting an inconsistent result here: if the ID
returned by queryValidPathId() is deleted from the database
concurrently, subsequent queries involving that ID will simply fail
(since IDs are never reused).
