Shea Levy b0c5c2ac34 import derivation: cleanup 
Before this there was a bug where a `find` was being called on a
not-yet-sorted set. The code was just a mess before anyway, so I cleaned
it up while fixing it.

Eelco Dolstra 8299aaf079 Disable vacuuming the DB after garbage collection 
Especially in WAL mode on a highly loaded machine, this is not a good
idea because it results in a WAL file of approximately the same size
ad the database, which apparently cannot be deleted while anybody is
accessing it.

Eelco Dolstra a3e5c99d66 nix-daemon: Call exit(), not _exit() 
This was preventing destructors from running. In particular, it was
preventing the deletion of the temproot file for each worker
process. It may also have been responsible for the excessive WAL
growth on Hydra (due to the SQLite database not being closed
properly).

Apparently broken by accident in
8e9140cfde.

Shea Levy 997defa166 Add functors (callable attribute sets). 
With this, attribute sets with a `__functor` attribute can be applied
just like normal functions. This can be used to attach arbitrary
metadata to a function without callers needing to treat it specially.

Shea Levy 6062b12160 Fix build on gcc < 4.7 2014-10-20 12:15:50 -04:00
Shea Levy f040159f77 Revert "Drop support for pre-c++11 compilers." 
The breakage this fixed can be worked around without removing support.

This reverts commit 84a13dc576.

Eelco Dolstra ecc2c8f464 Improve printing of ASTs 2014-10-20 09:13:21 +02:00
Shea Levy 84a13dc576 Drop support for pre-c++11 compilers. 
In particular, gcc 4.6's std::exception::~exception has an exception
specification in c++0x mode, which requires us to use that deprecated
feature in nix (and led to breakage after some recent changes that were
valid c++11).

nix already uses several c++11 features and gcc 4.7 has been around for
over 2 years.

Eelco Dolstra 6bb4c0b712 mkList: Scrub better 
Clearing v.app.right was not enough, because the length field of a
list only takes 32 bits, so the most significant 32 bits of v.app.left
(a.k.a. v.thunk.env) would remain. This could cause Boehm GC to
interpret it as a valid pointer.

This change reduces maximum RSS for evaluating the ‘tested’ job in
nixos/release-small.nix from 1.33 GiB to 0.80 GiB, and runtime by
about 8%.

Eelco Dolstra 022618c794 Handle cycles when printing a value 
So this no longer crashes with a stack overflow:

  nix-instantiate -E --eval 'let as = { x = as; }; in as'

Instead it prints:

  { x = { x = <CYCLE>; }; }
