2010-11-25* DrvInfo contains pointers to expressions, so DrvInfos should beEelco Dolstra
traced by the garbage collector. Otherwise "nix-env -u" can crash randomly.
2010-10-22* Store Value nodes outside of attribute sets. I.e., Attr now storesEelco 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.
2010-10-04* 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.
2010-04-21* Store user environment manifests as a Nix expression inEelco Dolstra
$out/manifest.nix rather than as an ATerm. (Hm, I thought I committed this two days ago...)
2010-04-19* Added parsing of manifests in ATerm format.Eelco Dolstra
2010-04-07* Update autoCallFunction() and findAlongAttrPath().Eelco Dolstra
2010-03-31* Implemented derivations.Eelco Dolstra
2009-06-30* Support integers and lists of strings in meta fields. This isEelco Dolstra
useful for fields like meta.maintainers, meta.priority (which can be a proper integer now) and even meta.license (if there are multiple licenses).
2007-05-01* nix-env -i: instead of breaking package ties by version, break themEelco Dolstra
by priority and version install. That is, if there are multiple packages with the same name, then pick the package with the highest priority, and only use the version if there are multiple packages with the same priority. This makes it possible to mark specific versions/variant in Nixpkgs more or less desirable than others. A typical example would be a beta version of some package (e.g., "gcc-4.2.0rc1") which should not be installed even though it is the highest version, except when it is explicitly selected (e.g., "nix-env -i gcc-4.2.0rc1"). * Idem for nix-env -u, only the semantics are a bit trickier since we also need to take into account the priority of the currently installed package (we never upgrade to a lower priority, unless --always is given).
2007-02-02* nix-env now maintains meta info (from the `meta' derivationEelco Dolstra
attribute) about installed packages in user environments. Thus, an operation like `nix-env -q --description' shows useful information not only on available packages but also on installed packages. * nix-env now passes the entire manifest as an argument to the Nix expression of the user environment builder (not just a list of paths), so that in particular the user environment builder has access to the meta attributes. * New operation `--set-flag' in nix-env to change meta info of installed packages. This will be useful to pass per-package policies to the user environment builder (e.g., how to resolve collision or whether to disable a package (NIX-80)) or upgrade policies in nix-env (e.g., that a package should be "masked", that is, left untouched by upgrade actions). Example: $ nix-env --set-flag enabled false ghc-6.4
2006-09-04* Use a proper namespace.Eelco Dolstra
* Optimise header file usage a bit. * Compile the parser as C++.
2006-07-28* `nix-instantiate ... --arg NAME VALUE': allow arguments to be passedEelco Dolstra
to functions from the command line. * nix-build: started removing backticks.
2006-07-26* Refactoring: get the selection path stuff out of getDerivations()Eelco Dolstra
and put it into a separate function findAlongAttrPath().
2006-07-25* Applied rbroek's patch from the branch atEelco Dolstra
https://svn.cs.uu.nl:12443/repos/trace/buildfarm-control/trunk/ext/nix/, with some modifications. This allows `nix-env -qa' to show the attribute path that can be used to unambiguously install a package using `nix-env -i -A'. Example: $ nix-env -f top-level/all-packages.nix -qaA subversion xorg-server subversionWithJava subversion-1.2.3 subversion subversion-1.3.2 subversion14 subversion-1.4.0pre-rc1 xorg.xorgserver xorg-server-1.1.0
2006-05-02* Huge reduction in memory use (2/3 or so on large nix-env -qasEelco Dolstra
operations): share ATermMaps between DrvInfos.
2006-03-10* `nix-env -qa --description' shows human-readable descriptions ofEelco Dolstra
packages (provided that they have a `meta.description' attribute). E.g., $ ./src/nix-env/nix-env -qa --description gcc gcc-4.0.2 GNU Compiler Collection, 4.0.x (cross-compiler for sparc-linux) gcc-4.0.2 GNU Compiler Collection, 4.0.x (cross-compiler for mips-linux) gcc-4.0.2 GNU Compiler Collection, 4.0.x (cross-compiler for arm-linux) gcc-4.0.2 GNU Compiler Collection, 4.0.x
2006-02-10* In nix-instantiate, allow us to specify a "path" to theEelco Dolstra
derivation(s) we're interested, e.g., $ nix-instantiate ./all-packages.nix --attr xlibs.libX11 List elements can also be selected: $ nix-instantiate ./build-for-release.nix --attr 0.subversion This allows a non-ambiguous specification of a derivation. Of course, this should also be added to nix-env and nix-build.
2006-02-08* Refactoring: move derivation evaluation to libexpr.Eelco Dolstra
