| 2011-07-06 | * In the ‘?’ operator, allow attribute paths. For instance, you can | Eelco Dolstra | 4 | -24/+47 | |
| write ‘attrs ? a.b’ to test whether ‘attrs’ has an attribute ‘a’ containing an attribute ‘b’. This is more convenient than ‘attrs ? a && attrs.a ? b’. Slight change in the semantics: it's no longer an error if the left-hand side of ‘?’ is not an attribute set. In that case it just returns false. So, ‘null ? foo’ no longer throws an error. | |||||
| 2011-02-10 | * Don't allocate a big initial GC address space on machines with | Eelco Dolstra | 1 | -11/+24 | |
| little RAM. Even if the memory isn't actually used, it can cause problems with the overcommit heuristics in the kernel. So use a VM space of 25% of RAM, up to 384 MB. | |||||
| 2011-02-09 | * Don't call GC_expand_hp unless we're actually using the garbage | Eelco Dolstra | 1 | -0/+18 | |
| collector. | |||||
| 2011-02-09 | Use $BDW_GC_LIBS instead of a custom variable. | Ludovic Courtès | 1 | -1/+1 | |
| 2011-01-14 | * builtins.substring: if "start" is beyond the end of the string, | Eelco Dolstra | 1 | -1/+1 | |
| return the empty string. | |||||
| 2010-11-25 | * DrvInfo contains pointers to expressions, so DrvInfos should be | Eelco Dolstra | 1 | -0/+4 | |
| traced by the garbage collector. Otherwise "nix-env -u" can crash randomly. | |||||
| 2010-10-28 | * new(UseGC) is inexplicably slower than GC_MALLOC, so prefer the | Eelco Dolstra | 1 | -4/+4 | |
| latter. | |||||
| 2010-10-28 | * Handle out of memory condition. | Eelco Dolstra | 1 | -5/+5 | |
| 2010-10-24 | * When allocating an attribute set, reserve enough space for all | Eelco Dolstra | 3 | -25/+18 | |
| elements. This prevents the vector from having to resize itself. | |||||
| 2010-10-24 | * Keep attribute sets in sorted order to speed up attribute lookups. | Eelco Dolstra | 9 | -139/+172 | |
| * Simplify the representation of attributes in the AST. * Change the behaviour of listToAttrs() in case of duplicate names. | |||||
| 2010-10-24 | * Don't create thunks for variable lookups (if possible). This | Eelco Dolstra | 3 | -23/+60 | |
| significantly reduces the number of values allocated (e.g. from 8.7m to 4.9m for the Bittorrent test). | |||||
| 2010-10-24 | * Store attribute sets as a vector instead of a map (i.e. a red-black | Eelco Dolstra | 7 | -90/+129 | |
| 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). | |||||
| 2010-10-23 | * Fix compiling without Boehm. | Eelco Dolstra | 1 | -10/+8 | |
| * Fix the stats. | |||||
| 2010-10-23 | * Optimise string constants by putting them in the symbol table. | Eelco Dolstra | 4 | -39/+55 | |
| 2010-10-23 | * Make Value smaller by not storing redundant PrimOp info. | Eelco Dolstra | 2 | -25/+44 | |
| * Clear pointers in Values after overwriting them to make sure that no objects are kept alive unnecessarily. | |||||
| 2010-10-23 | * Remove allocValues(). | Eelco Dolstra | 3 | -34/+12 | |
| 2010-10-22 | * In environments, store pointers to values rather than values. This | Eelco Dolstra | 2 | -35/+25 | |
| improves GC effectiveness a bit more (because a live value doesn't keep other values in the environment plus the parent environments alive), and removes the need for copy nodes. | |||||
| 2010-10-22 | * Store Value nodes outside of attribute sets. I.e., Attr now stores | Eelco Dolstra | 12 | -116/+135 | |
| 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. | |||||
| 2010-10-22 | * Make building against the Boehm GC a configure option. | Eelco Dolstra | 3 | -7/+25 | |
| 2010-10-20 | * Keep some more stats. | Eelco Dolstra | 2 | -0/+12 | |
| 2010-10-20 | * Use the Boehm garbage collector to reclaim unused memory in the Nix | Eelco Dolstra | 3 | -11/+20 | |
| expression evaluator. | |||||
| 2010-10-04 | * Make sure that config.h is included before the system headers, | Eelco Dolstra | 7 | -18/+16 | |
| 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 | * If std::tr1::unordered_set is unavailable, use std::set. | Eelco Dolstra | 1 | -0/+9 | |
| 2010-10-04 | * Hack needed for GCC 4.3.2 on OpenSolaris. | Eelco Dolstra | 1 | -1/+1 | |
| 2010-08-27 | * Oops - "null" was displayed as "true". | Eelco Dolstra | 1 | -1/+1 | |
| 2010-08-02 | * Optimisation in the // operator: if one of the sets is empty, return | Eelco Dolstra | 1 | -6/+8 | |
| the other set. | |||||
| 2010-08-02 | * intersectAttrs: optimise for the case where the second set is larger | Eelco Dolstra | 1 | -7/+7 | |
| than the first set. (That's usually the case with callPackage.) | |||||
| 2010-06-10 | * builtins.toXML: propagate the string context. This is a regression | Eelco Dolstra | 3 | -5/+12 | |
| from the old ATerm-based evaluator. | |||||
| 2010-06-02 | (no commit message) | Eelco Dolstra | 1 | -0/+1 | |
| 2010-06-01 | * Turn build errors during evaluation into EvalErrors. | Eelco Dolstra | 2 | -1/+6 | |
| 2010-05-18 | * The << operator on values should be const. | Eelco Dolstra | 3 | -3/+3 | |
| 2010-05-15 | * Restore the __overrides feature that was lost somewhere in the | Eelco Dolstra | 2 | -3/+21 | |
| fast-eval branch. | |||||
| 2010-05-12 | * Print attributes in sorted order. | Eelco Dolstra | 1 | -2/+7 | |
| 2010-05-12 | * Implemented tryEval, the last missing primop in the fast-eval | Eelco Dolstra | 1 | -12/+6 | |
| branch. Also added a test for tryEval. | |||||
| 2010-05-07 | (no commit message) | Eelco Dolstra | 1 | -0/+2 | |
| 2010-05-07 | * Sync with the trunk. | Eelco Dolstra | 3 | -21/+45 | |
| 2010-05-07 | * Store position info for inherited attributes. | Eelco Dolstra | 4 | -25/+29 | |
| 2010-05-07 | * Updated addErrorContext. | Eelco Dolstra | 1 | -6/+7 | |
| 2010-05-07 | * Keep track of the source positions of attributes. | Eelco Dolstra | 7 | -76/+107 | |
| 2010-05-06 | * Store attribute positions in the AST and report duplicate attribute | Eelco Dolstra | 5 | -54/+53 | |
| errors with position info. * For all positions, use the position of the first character of the first token, rather than the last character of the first token plus one. | |||||
| 2010-04-23 | * Don't need the test program anymore. | Eelco Dolstra | 2 | -135/+0 | |
| 2010-04-22 | * Simplify the implementation of `with'. This gives a 7% speedup in | Eelco Dolstra | 4 | -30/+15 | |
| evaluating the NixOS system configuration. | |||||
| 2010-04-22 | * Check for duplicate attribute names / function arguments. `make | Eelco Dolstra | 2 | -44/+48 | |
| check' now succeeds :-) * An attribute set such as `{ foo = { enable = true; }; foo.port = 23; }' now parses. It was previously rejected, but I'm too lazy to implement the check. (The only reason to reject it is that the reverse, `{ foo.port = 23; foo = { enable = true; }; }', is rejected, which is kind of ugly.) | |||||
| 2010-04-22 | * String equality tests should take the context into account. All the | Eelco Dolstra | 2 | -4/+12 | |
| evaluation test cases now succeed. | |||||
| 2010-04-21 | * Fix the interpretation of ''\<character> in indented strings. | Eelco Dolstra | 1 | -1/+1 | |
| 2010-04-21 | * Fixed builtins.genericClosure. | Eelco Dolstra | 3 | -26/+62 | |
| 2010-04-21 | * Store user environment manifests as a Nix expression in | Eelco Dolstra | 5 | -40/+38 | |
| $out/manifest.nix rather than as an ATerm. (Hm, I thought I committed this two days ago...) | |||||
| 2010-04-19 | * Drop the dependency on the ATerm library. | Eelco Dolstra | 1 | -4/+2 | |
| 2010-04-19 | * Don't use the ATerm library for parsing/printing .drv files. | Eelco Dolstra | 1 | -1/+1 | |
| 2010-04-19 | * Added parsing of manifests in ATerm format. | Eelco Dolstra | 2 | -6/+15 | |
