From 71f026292ba1b401237a16ab6e0fb57c36c93df5 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Thu, 1 Apr 2010 09:55:57 +0000 Subject: * Make `derivation' lazy again for performance. It also turns out that there are some places in Nixpkgs (php_configurable / composableDerivation, it seems) that call `derivation' with incorrect arguments (namely, the `name' attribute missing) but get away with it because of laziness. --- src/libexpr/eval.hh | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'src/libexpr/eval.hh') diff --git a/src/libexpr/eval.hh b/src/libexpr/eval.hh index 13ea269fc69d..34b658ce13e4 100644 --- a/src/libexpr/eval.hh +++ b/src/libexpr/eval.hh @@ -104,6 +104,14 @@ static inline void mkBool(Value & v, bool b) } +static inline void mkThunk(Value & v, Env & env, Expr expr) +{ + v.type = tThunk; + v.thunk.env = &env; + v.thunk.expr = expr; +} + + void mkString(Value & v, const char * s); void mkString(Value & v, const string & s, const PathSet & context = PathSet()); void mkPath(Value & v, const char * s); -- cgit 1.4.1
