* 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 17:55:38 +00:00			`#include <string>`

replace most Pos objects/ptrs with indexes into a position table Pos objects are somewhat wasteful as they duplicate the origin file name and input type for each object. on files that produce more than one Pos when parsed this a sizeable waste of memory (one pointer per Pos). the same goes for ptr<Pos> on 64 bit machines: parsing enough source to require 8 bytes to locate a position would need at least 8GB of input and 64GB of expression memory. it's not likely that we'll hit that any time soon, so we can use a uint32_t index to locate positions instead. 2022-03-04 18:31:59 +00:00			`Value & v, std::ostream & out, PathSet & context, const PosIdx pos);`
toXML: display errors position - This change applies to builtins.toXML and inner workings - Proof of concept: ```nix let e = builtins.toXML e; in e ``` - Before: ``` $ nix-instantiate --eval poc.nix error: infinite recursion encountered ``` - After: ``` $ nix-instantiate --eval poc.nix error: infinite recursion encountered at /data/github/kamadorueda/nix/poc.nix:1:9: 1\| let e = builtins.toXML e; in e \| ``` 2021-11-14 01:29:31 +00:00
