2010-10-29 * Document Boehm GC support.Eelco Dolstra4-1/+40
2010-10-29 * Use pkgconfig to locate the Boehm GC (as suggested by Ludo), ifEelco Dolstra2-10/+10
--enable-gc is given.
2010-10-29 * Set libgc's initial heap size to 384 MiB to prevent garbageEelco Dolstra1-0/+12
collection in most cases (and therefore its performance overhead).
2010-10-28 * new(UseGC) is inexplicably slower than GC_MALLOC, so prefer theEelco Dolstra1-4/+4
latter.
2010-10-28 * Handle out of memory condition.Eelco Dolstra5-10/+28
2010-10-26 * Install config.h.Eelco Dolstra1-0/+2
2010-10-24 * We need Bison 2.4 now.Eelco Dolstra1-1/+2
2010-10-24 * When allocating an attribute set, reserve enough space for allEelco Dolstra4-28/+21
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 Dolstra12-147/+185
* 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). ThisEelco Dolstra3-23/+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-blackEelco Dolstra7-90/+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 Dolstra1-10/+8
* Fix the stats.
2010-10-23 * Regression test for listToAttr's behaviour if an attribute nameEelco Dolstra2-2/+3
occurs multiple times.
2010-10-23 * Optimise string constants by putting them in the symbol table.Eelco Dolstra4-39/+55
2010-10-23 * Make Value smaller by not storing redundant PrimOp info.Eelco Dolstra2-25/+44
* Clear pointers in Values after overwriting them to make sure that no objects are kept alive unnecessarily.
2010-10-23 * Remove allocValues().Eelco Dolstra4-36/+14
2010-10-22 * In environments, store pointers to values rather than values. ThisEelco Dolstra2-35/+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 * Regression test for __overrides.Eelco Dolstra2-0/+10
2010-10-22 * Store Value nodes outside of attribute sets. I.e., Attr now storesEelco Dolstra15-130/+150
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 Dolstra6-14/+42
2010-10-20 * Keep some more stats.Eelco Dolstra2-0/+12
2010-10-20 * Use the Boehm garbage collector to reclaim unused memory in the NixEelco Dolstra5-15/+29
expression evaluator.
2010-10-20 * Evaluator garbage collection branch.Eelco Dolstra0-0/+0
2010-10-06 nix manual: fix 'install' -> 'uninstall' in garbage collection section of ↵Rob Vermaas1-1/+1
introduction
2010-10-04 * In the referrers test, lower the nesting depth from 2500 to 1000 toEelco Dolstra1-1/+1
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 Dolstra12-29/+29
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 Dolstra2-0/+16
2010-10-04 * "type -P" isn't portable.Eelco Dolstra1-1/+1
2010-10-04 * In printMsg(), ignore failing writes to stderr if we're in anEelco Dolstra1-1/+10
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 Dolstra1-1/+1
2010-09-14 * Doh. Remove debug message.Eelco Dolstra1-1/+0
2010-08-27 * Oops - "null" was displayed as "true".Eelco Dolstra1-1/+1
2010-08-24 * nix-build: pass --cores.Eelco Dolstra1-1/+1
2010-08-17 * Bump the version number.Eelco Dolstra1-1/+1
2010-08-17 * rpmBuild already includes the disk image in the output name.Eelco Dolstra1-1/+1
2010-08-17 * Update date.Eelco Dolstra1-1/+2
2010-08-17 * Document --cores in the manual.Eelco Dolstra5-5/+46
2010-08-16 * Typo.Eelco Dolstra1-1/+1
2010-08-16 * Remove the "tarball" jobset argument.Eelco Dolstra1-53/+20
2010-08-16 * Nix 0.16 release notes.Eelco Dolstra1-0/+53
2010-08-12 * Urgh, this was supposed to go in the trunk...Eelco Dolstra1-3/+0
2010-08-12 * Make --cores work when building through the Nix daemon.Eelco Dolstra3-1/+7
2010-08-04 * Remove "auto" and "guess" as synonyms for 0 in the handling ofEelco Dolstra2-20/+8
build-cores and --cores. They're superfluous and just complicate the parsing.
2010-08-04 * Set the default system filter to "*". This ensures that (forEelco Dolstra1-7/+13
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, returnEelco Dolstra1-6/+8
the other set.
2010-08-02 * intersectAttrs: optimise for the case where the second set is largerEelco Dolstra1-7/+7
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 Dolstra1-1/+6
2010-07-15 src/bsdiff-4.3/Makefile.am: include the 'compat-include' directory in ↵Peter Simons1-0/+2
distribution tarballs
2010-06-25 tests/build-hook.hook.sh: prefer more portable `...` syntax over $(...) for ↵Peter Simons1-2/+2
running sub-shells The /bin/sh interpreter on Solaris doesn't understand $(...) syntax for running sub-shells. Consequently, this test fails on Solaris. To remedy the situation, the script either needs to be run by /bin/bash -- which is non-standard --, or it needs to use the ancient but portable `...` syntax.
2010-06-24 Revert "configure.ac: make flex and bison required programs"Peter Simons1-2/+2
This reverts commit 22405. Apparently, these programs aren't necessarily required when building from a release archive.
