| 2011-01-14 | Remove useless <config.h> inclusion from public header. | Ludovic Courtès | |
| 2010-11-25 | * DrvInfo contains pointers to expressions, so DrvInfos should be | Eelco Dolstra | |
| traced by the garbage collector. Otherwise "nix-env -u" can crash randomly. | |||
| 2010-10-29 | * Merge the GC branch. | Eelco Dolstra | |
| 2010-10-29 | * Document Boehm GC support. | Eelco Dolstra | |
| 2010-10-29 | * Use pkgconfig to locate the Boehm GC (as suggested by Ludo), if | Eelco Dolstra | |
| --enable-gc is given. | |||
| 2010-10-29 | * Set libgc's initial heap size to 384 MiB to prevent garbage | Eelco Dolstra | |
| collection in most cases (and therefore its performance overhead). | |||
| 2010-10-28 | * new(UseGC) is inexplicably slower than GC_MALLOC, so prefer the | Eelco Dolstra | |
| latter. | |||
| 2010-10-28 | * Handle out of memory condition. | Eelco Dolstra | |
| 2010-10-26 | * Install config.h. | Eelco Dolstra | |
| 2010-10-24 | * We need Bison 2.4 now. | Eelco Dolstra | |
| 2010-10-24 | * When allocating an attribute set, reserve enough space for all | Eelco Dolstra | |
| 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 | |
| * 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 | |
| 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 | |
| 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 | |
| * Fix the stats. | |||
| 2010-10-23 | * Regression test for listToAttr's behaviour if an attribute name | Eelco Dolstra | |
| occurs multiple times. | |||
| 2010-10-23 | * Optimise string constants by putting them in the symbol table. | Eelco Dolstra | |
| 2010-10-23 | * Make Value smaller by not storing redundant PrimOp info. | Eelco Dolstra | |
| * Clear pointers in Values after overwriting them to make sure that no objects are kept alive unnecessarily. | |||
| 2010-10-23 | * Remove allocValues(). | Eelco Dolstra | |
| 2010-10-22 | * In environments, store pointers to values rather than values. This | Eelco Dolstra | |
| 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 | * Regression test for __overrides. | Eelco Dolstra | |
| 2010-10-22 | * Store Value nodes outside of attribute sets. I.e., Attr now stores | Eelco Dolstra | |
| 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 | |
| 2010-10-20 | * Keep some more stats. | Eelco Dolstra | |
| 2010-10-20 | * Use the Boehm garbage collector to reclaim unused memory in the Nix | Eelco Dolstra | |
| expression evaluator. | |||
| 2010-10-20 | * Evaluator garbage collection branch. | Eelco Dolstra | |
| 2010-10-06 | nix manual: fix 'install' -> 'uninstall' in garbage collection section of ↵ | Rob Vermaas | |
| introduction | |||
| 2010-10-04 | * In the referrers test, lower the nesting depth from 2500 to 1000 to | Eelco Dolstra | |
| prevent hitting a stack overflow bug in the garbage collector. | |||
| 2010-10-04 | * Make sure that config.h is included before the system headers, | Eelco Dolstra | |
| 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 | |
| 2010-10-04 | * "type -P" isn't portable. | Eelco Dolstra | |
| 2010-10-04 | * In printMsg(), ignore failing writes to stderr if we're in an | Eelco Dolstra | |
| exception handler, otherwise throw an exception. We need to ignore write errors in exception handlers to ensure that cleanup code runs to completion if the other side of stderr has been closed unexpectedly. | |||
| 2010-10-04 | * Hack needed for GCC 4.3.2 on OpenSolaris. | Eelco Dolstra | |
| 2010-09-14 | * Doh. Remove debug message. | Eelco Dolstra | |
| 2010-08-27 | * Oops - "null" was displayed as "true". | Eelco Dolstra | |
| 2010-08-24 | * nix-build: pass --cores. | Eelco Dolstra | |
| 2010-08-17 | * Bump the version number. | Eelco Dolstra | |
| 2010-08-17 | * rpmBuild already includes the disk image in the output name. | Eelco Dolstra | |
| 2010-08-17 | * Update date. | Eelco Dolstra | |
| 2010-08-17 | * Document --cores in the manual. | Eelco Dolstra | |
| 2010-08-16 | * Typo. | Eelco Dolstra | |
| 2010-08-16 | * Remove the "tarball" jobset argument. | Eelco Dolstra | |
| 2010-08-16 | * Nix 0.16 release notes. | Eelco Dolstra | |
| 2010-08-12 | * Urgh, this was supposed to go in the trunk... | Eelco Dolstra | |
| 2010-08-12 | * Make --cores work when building through the Nix daemon. | Eelco Dolstra | |
| 2010-08-04 | * Remove "auto" and "guess" as synonyms for 0 in the handling of | Eelco Dolstra | |
| build-cores and --cores. They're superfluous and just complicate the parsing. | |||
| 2010-08-04 | * Set the default system filter to "*". This ensures that (for | Eelco Dolstra | |
| instance) "nix-env -i wine" works on x86_64-linux, even though Wine is built on i686-linux. In the event that there are multiple matching derivations, prefer those built for the current system. | |||
| 2010-08-02 | * Optimisation in the // operator: if one of the sets is empty, return | Eelco Dolstra | |
| the other set. | |||
| 2010-08-02 | * intersectAttrs: optimise for the case where the second set is larger | Eelco Dolstra | |
| than the first set. (That's usually the case with callPackage.) | |||
| 2010-07-21 | * Don't barf if the source NAR for a patch has disappeared. | Eelco Dolstra | |
