742a8046de Store short strings in Values 
The vast majority of strings are < 16 bytes, and so can be stored
directly in a Value. This saves a heap allocation and an indirection.

nix-shell: Use bashInteractive from <nixpkgs> 
This adds about 0.1s to nix-shell runtime in the case where
bashInteractive already exists.

getDerivations(): Filter out packages with bad derivation names 
In particular, this disallows attribute names containing dots or
starting with dots. Hydra already disallowed these. This affects the
following packages in Nixpkgs master:

  2048-in-terminal
  2bwm
  389-ds-base
  90secondportraits
  lispPackages.3bmd
  lispPackages.hu.dwim.asdf
  lispPackages.hu.dwim.def

Closes #1342.

Revert "Get rid of unicode quotes (#1140)" 
This reverts commit f78126bfd6. There
really is no need for such a massive change...

41633f9f73 Improved logging abstraction 
This also gets rid of --log-type, since the nested log type isn't
useful in a multi-threaded situation, and nobody cares about the
"pretty" log type.

b83801f8b3 Optimize small lists 
The value pointers of lists with 1 or 2 elements are now stored in the
list value itself. In particular, this makes the "concatMap (x: if
cond then [(f x)] else [])" idiom cheaper.

or (in XML mode)

70f75be199 getDerivation(): Don't always quietly ignore assertion failure 
Ignoring assertion failures makes some sense for nix-env -qa, but not
for nix-instantiate/nix-build or hydra-eval-jobs.

f491ae97d4 * Inline some functions and get rid of the indirection through 
EvalState::eval().  This gives a 12% speedup on ‘nix-instantiate
  /etc/nixos/nixos/ -A system --readonly-mode’ (from 1.01s to 0.89s).

e0b7fb8f27 * Keep attribute sets in sorted order to speed up attribute lookups. 
* Simplify the representation of attributes in the AST.
* Change the behaviour of listToAttrs() in case of duplicate names.

Eelco Dolstra
0b305c534f * Store attribute sets as a vector instead of a map (i.e. a red-black 
tree).  This saves a lot of memory.  The vector should be sorted so
  that names can be looked up using binary search, but this is not the
  case yet.  (Surprisingly, looking up attributes using linear search
  doesn't have a big impact on performance.)

  Memory consumption for

    $ nix-instantiate /etc/nixos/nixos/tests -A bittorrent.test --readonly-mode

  on x86_64-linux with GC enabled is now 185 MiB (compared to 946
  MiB on the trunk).

41c45a9b31 * Store Value nodes outside of attribute sets. I.e., Attr now stores 
a pointer to a Value, rather than the Value directly.  This improves
  the effectiveness of garbage collection a lot: if the Value is
  stored inside the set directly, then any live pointer to the Value
  causes all other attributes in the set to be live as well.

02c1dac909 * In an nested with' where the inner with is a variable (with ...; 
with someVar; ...'), the contents of the variable would be
  clobbered.  (The attributes in the outer `with' were added to the
  variable.)
 2010-04-16 13:44:02 +00:00
Eelco Dolstra
04c4bd3624 * Store lists as lists of pointers to values rather than as lists of 
values.  This improves sharing and gives another speed up.
  Evaluation of the NixOS system attribute is now almost 7 times
  faster than the old evaluator.
 2010-04-15 00:37:36 +00:00

ac1e8f40d4 * Use a symbol table to represent identifiers and attribute names 
efficiently.  The symbol table ensures that there is only one copy
  of each symbol, thus allowing symbols to be compared efficiently
  using a pointer equality test.
