Use "#pragma once" to prevent repeated header file inclusion 2012-07-18 20:59:03 +02:00			`#pragma once`
* Refactoring: get the selection path stuff out of getDerivations() and put it into a separate function findAlongAttrPath(). 2006-07-26 17:05:15 +02:00
* Make sure that config.h is included before the system headers, because it defines _FILE_OFFSET_BITS. Without this, on OpenSolaris the system headers define it to be 32, and then the 32-bit stat() ends up being called with a 64-bit "struct stat", or vice versa. This also ensures that we get 64-bit file sizes everywhere. * Remove the redundant call to stat() in parseExprFromFile(). The file cannot be a symlink because that's the exit condition of the loop before. 2010-10-04 19:55:38 +02:00			`#include "eval.hh"`

Work on Values instead of Exprs This prevents some duplicate evaluation in nix-env and nix-instantiate. Also, when traversing ~/.nix-defexpr, only read regular files with the extension .nix. Previously it was reading files like .../channels/binary-caches/<name>. The only reason this didn't cause problems is pure luck (namely, <name> shadows an actual Nix expression, the binary-caches files happen to be syntactically valid Nix expressions, and we iterate over the directory contents in just the right order). 2013-09-03 15:17:51 +02:00			`Value * findAlongAttrPath(EvalState & state, const string & attrPath,`
