| 2010-04-16 | * _combineChannels shouldn't be an integer. | Eelco Dolstra | |
| 2010-04-16 | * Improve sharing a bit. | Eelco Dolstra | |
| 2010-04-16 | * Remove some redundant tests. | Eelco Dolstra | |
| 2010-04-16 | * In an nested `with' where the inner with is a variable (`with ...; | Eelco Dolstra | |
| with someVar; ...'), the contents of the variable would be clobbered. (The attributes in the outer `with' were added to the variable.) | |||
| 2010-04-15 | * Store lists as lists of pointers to values rather than as lists of | Eelco Dolstra | |
| 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. | |||
| 2010-04-14 | * Better stats. | Eelco Dolstra | |
| 2010-04-14 | * Implemented inherit. | Eelco Dolstra | |
| 2010-04-14 | * Fix builtins. | Eelco Dolstra | |
| 2010-04-14 | * Refactoring: move variable uses to a separate class. | Eelco Dolstra | |
| 2010-04-14 | * Implemented withs. | Eelco Dolstra | |
| 2010-04-14 | * After parsing, compute level/displacement pairs for each variable | Eelco Dolstra | |
| use site, allowing environments to be stores as vectors of values rather than maps. This should speed up evaluation and reduce the number of allocations. | |||
| 2010-04-14 | * Remove more obsolete code. | Eelco Dolstra | |
| 2010-04-14 | * Get nix-env to compile again. | Eelco Dolstra | |
| 2010-04-14 | * Change the semantics of "with" so that inner "withs" take | Eelco Dolstra | |
| precedence, i.e. `with {x=1;}; with {x=2;}; x' evaluates to 2'. This has a simpler implementation and seems more natural. There doesn't seem to be any code in Nixpkgs or NixOS that relies on the old behaviour. | |||
| 2010-04-13 | * Use std::tr1::unordered_set instead of std::set for the symbol | Eelco Dolstra | |
| table. This gives a 10% speed increase on `nix-instantiate /etc/nixos/nixos -A system --readonly-mode'. | |||
| 2010-04-13 | * Evaluate lets directly (i.e. without desugaring to `rec { attrs...; | Eelco Dolstra | |
| <let-body> = e; }.<let-body>). This prevents the unnecessary allocation of an attribute set. | |||
| 2010-04-13 | * Use a symbol table to represent identifiers and attribute names | Eelco Dolstra | |
| 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. | |||
| 2010-04-12 | * Finished the ATerm-less parser. | Eelco Dolstra | |
| 2010-04-12 | * Remove some obsolete functions. | Eelco Dolstra | |
| 2010-04-12 | * Indented strings. | Eelco Dolstra | |
| 2010-04-12 | * More missing constructs. | Eelco Dolstra | |
| 2010-04-12 | * Don't use ATerms for the abstract syntax trees anymore. Not | Eelco Dolstra | |
| finished yet. | |||
| 2010-04-12 | * Don't use ATerms to represent integers in the lexer. | Eelco Dolstra | |
| 2010-04-12 | * Hack to support builderDefs expressions. | Eelco Dolstra | |
| 2010-04-12 | * Doh. | Eelco Dolstra | |
| 2010-04-12 | (no commit message) | Eelco Dolstra | |
| 2010-04-09 | * Keep more statistics about stack space usage. | Eelco Dolstra | |
| * Reduce stack space usage. | |||
| 2010-04-08 | * Remove a lot of dead code. | Eelco Dolstra | |
| 2010-04-08 | * Fix blackholing. If evaluation fails due to an assertion failure, | Eelco Dolstra | |
| then the blackhole has to be removed to ensure that repeated evaluation of the same value gives an assertion failure again rather than an "infinite recursion" error. | |||
| 2010-04-07 | * Update autoCallFunction() and findAlongAttrPath(). | Eelco Dolstra | |
| 2010-04-07 | * expr-to-xml -> value-to-xml. | Eelco Dolstra | |
| 2010-04-07 | * Implemented the primops necessary for generating the NixOS manual. | Eelco Dolstra | |
| 2010-04-06 | * In eval(), don't use the target value `v' as a temporary. | Eelco Dolstra | |
| Overwriting `v' breaks when the expression evaluation to an assertion failure or throw. | |||
| 2010-04-01 | * Removed the `~' operator. | Eelco Dolstra | |
| 2010-04-01 | * Quick hack to make coerceToString work more or less correctly on | Eelco Dolstra | |
| nested lists. `nix-instantiate' can now evaluate the NixOS system derivation attribute correctly (in 2.1s on my laptop vs. 6.2s for the trunk). | |||
| 2010-04-01 | * Improve sharing. | Eelco Dolstra | |
| 2010-04-01 | * Functions are incomparable. | Eelco Dolstra | |
| 2010-04-01 | * Make `derivation' lazy again for performance. It also turns out | Eelco Dolstra | |
| 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. | |||
| 2010-03-31 | * Fixed the trace primop and path comparison. | Eelco Dolstra | |
| * Removed exprToString and stringToExpr because there is no ATerm representation to work on anymore (and exposing the internals of the evaluator like this is not a good idea anyway). | |||
| 2010-03-31 | * Handle string contexts. `nix-instantiate' can now correctly compute | Eelco Dolstra | |
| the `firefoxWrapper' attribute in Nixpkgs, and it's about 3 times faster than the trunk :-) | |||
| 2010-03-31 | * Get nix-env to compile. | Eelco Dolstra | |
| 2010-03-31 | * Cache parse trees to prevent repeated parsing of imported Nix | Eelco Dolstra | |
| expressions. | |||
| 2010-03-31 | * Implemented derivations. | Eelco Dolstra | |
| 2010-03-31 | * Implemented `rec { inherit ...; }'. | Eelco Dolstra | |
| 2010-03-31 | * Compare nulls. | Eelco Dolstra | |
| 2010-03-30 | * More primops. | Eelco Dolstra | |
| 2010-03-30 | * More operators / primops. | Eelco Dolstra | |
| 2010-03-30 | * More primops. | Eelco Dolstra | |
| 2010-03-30 | * More primops. | Eelco Dolstra | |
| 2010-03-30 | * Implemented `map'. | Eelco Dolstra | |
