2008-09-17* Garbage collector: added an option `--use-atime' to delete paths inEelco Dolstra
order of ascending last access time. This is useful in conjunction with --max-freed or --max-links to prefer deleting non-recently used garbage, which is good (especially in the build farm) since garbage may become live again. The code could easily be modified to accept other criteria for ordering garbage by changing the comparison operator used by the priority queue in collectGarbage().
2008-09-08* Doh.Eelco Dolstra
2008-09-02* When writing the user environment manifest, filter out non-stringEelco Dolstra
attributes from the meta attribute. Not doing so caused nix-env to barf on the "psi" package, which has a meta.function attribute, the textual serialisation of which causes a gigantic string to be produced --- so big that it causes nix-env to run out of memory. Note however that "meta" really only should contain strings. meta.function should be passthru.function.
2008-08-29* Extend the ATerm suppressions to 64-bit.Eelco Dolstra
2008-08-29(no commit message)Eelco Dolstra
2008-08-29Added nix-http-export.cgi to extra distributed scripts; so it can be ↵Michael Raskin
installed from releases, not only from SVN.
2008-08-27* Explicitly set PWD to prevent problems with chroot builds. InEelco Dolstra
particular, dietlibc cannot figure out the cwd because the inode of the current directory doesn't appear in .. (because getdents returns the inode of the mount point).
2008-08-27* Create a /tmp with 1777 permission in the chroot. Some buildersEelco Dolstra
need a writable /tmp (they don't respect $TMPDIR).
2008-08-26* Require that __overrides is defined as a non-recursive attributeEelco Dolstra
(which means it can only be defined via "inherit"), otherwise we get scoping bugs, since __overrides can't be recursive (or at least, it would be hard).
2008-08-25* Disable chroot builds for fixed-output derivations so that we don'tEelco Dolstra
need /etc in the chroot (in particular, /etc/resolv.conf for fetchurl). Not having /etc/resolv.conf in the chroot is a good thing, since we don't want normal derivations to download files.
2008-08-25* Evaluate attributes in sorted order for better determinism.Eelco Dolstra
2008-08-25* Minor simplification.Eelco Dolstra
2008-08-25* Doh.Eelco Dolstra
2008-08-25* Strip off the `.nix' suffix from the attribute name for files inEelco Dolstra
~/.nix-defexpr, otherwise the attribute cannot be selected with the `-A' option. Useful if you want to stick a Nix expression directly in ~/.nix-defexpr.
2008-08-22* Simplify the Valgrind suppressions using wildcards.Eelco Dolstra
2008-08-19* Some more ATerm Valgrind suppressions.Eelco Dolstra
2008-08-14Fixing an obvious typo in override code. I do not know whether it works ↵Michael Raskin
correctly after the change, but at least it ca nbe compiled now.
2008-08-14* Another experimental feature: a way to truly override attributes inEelco Dolstra
a rec. This will be very useful to allow end-user customisation of all-packages.nix, for instance globally overriding GCC or some other dependency. The // operator doesn't cut it: you could replace the "gcc" attribute, but all other attributes would continue to reference the original value due to the substitution semantics of rec. The syntax is a bit hacky but this is to allow backwards compatibility.
2008-08-14* Added an experimental feature suggested by Andres: ellipses ("...")Eelco Dolstra
in attribute set pattern matches. This allows defining a function that takes *at least* the listed attributes, while ignoring additional attributes. For instance, {stdenv, fetchurl, fuse, ...}: stdenv.mkDerivation { ... }; defines a function that requires an attribute set that contains the specified attributes but ignores others. The main advantage is that we can then write in all-packages.nix aefs = import ../bla/aefs pkgs; instead of aefs = import ../bla/aefs { inherit stdenv fetchurl fuse; }; This saves a lot of typing (not to mention not having to update all-packages.nix with purely mechanical changes). It saves as much typing as the "args: with args;" style, but has the advantage that the function arguments are properly declared (not implicit in what the body of the "with" uses).
2008-08-14* Backward compatibility check to prevent nixos-rebuild from barfingEelco Dolstra
when upgrading Nix.
2008-08-14* @-patterns as in Haskell. For instance, in a function definitionEelco Dolstra
f = args @ {x, y, z}: ...; `args' refers to the argument as a whole, which is further pattern-matched against the attribute set pattern {x, y, z}.
2008-08-14* "pattern" non-terminal.Eelco Dolstra
2008-08-14* Refactoring: combine functions that take an attribute set andEelco Dolstra
functions that take a single argument (plain lambdas) into one AST node (Function) that contains a Pattern node describing the arguments. Current patterns are single lazy arguments (VarPat) and matching against an attribute set (AttrsPat). This refactoring allows other kinds of patterns to be added easily, such as Haskell-style @-patterns, or list pattern matching.
2008-08-14* Increase the sleep periods a bit to make the test less likely toEelco Dolstra
fail on slow machines. Of course it would be better if this test wasn't timing dependent...
2008-08-11* Removed the "valid values" feature. Nobody uses it anyway.Eelco Dolstra
2008-08-06Updates to nix-reduce-buildMichael Raskin
Common code in local build package sources refactored out in a function; before building the real set of derivations needed is found (slightly slower for only one build strategy, but less garbage on output and better performance for multiple build strategies). Now you have full choice of best-effort build regardless of method (substituters or actual build), using substituters, building only fixed derivations (should get you all the downloads) and local build without even trying substituters. Some minor fix in the help text about behavior with no package sources.
2008-08-05* Moved some stuff to the Nixpkgs manual.Eelco Dolstra
* Updated the release notes.
2008-08-05* Better error checking of the data from the substituters.Eelco Dolstra
2008-08-04* Use optimistic profile locking for nix-env operations like `-i' andEelco Dolstra
`-u'. Instead of acquiring an exclusive lock on the profile for the entire duration of the operation, we just perform the operation optimistically (without an exclusive lock), and check at the end whether the profile changed while we were busy (i.e., the symlink target changed). If so, the operation is restarted. Restarting is generally cheap, since the build results are still in the Nix store. Most of the time, only the user environment has to be rebuilt.
2008-08-04* Fix the tests.Eelco Dolstra
2008-08-04* `nix-env --set': support --dry-run.Eelco Dolstra
2008-08-04* nix-build: `--dry-run' flag.Eelco Dolstra
2008-08-04* `nix-store --realise': print what paths will be built/downloaded,Eelco Dolstra
just like nix-env. * `nix-store --realise': --dry-run option.
2008-08-04* Doh.Eelco Dolstra
2008-08-04* build.cc: only use a substituter if it returns info for a path.Eelco Dolstra
2008-08-04* Always show what paths we're going to build/download (as inEelco Dolstra
--dry-run). Maybe there should be an option to turn this on/off?
2008-08-04* nix-env --dry-run: show the total size of the substituterEelco Dolstra
downloads.
2008-08-04* querySubstitutablePathInfo: work properly when run via the daemon.Eelco Dolstra
* --dry-run: print the paths that we don't know how to build/substitute.
2008-08-02Updates to nix-reduce-build: only realize fixed derivations if user asks so, ↵Michael Raskin
or only use substituters. Oh, and add possibility to use : for things like /etc/nixos/nixpkgs:-A:gnused
2008-08-02* Make nix-env --dry-run print the paths to be substituted correctlyEelco Dolstra
again. (After the previous substituter mechanism refactoring I didn't update the code that obtains the references of substitutable paths.) This required some refactoring: the substituter programs are now kept running and receive/respond to info requests via stdin/stdout.
2008-07-24* Print a better error message when a non-derivation attribute set isEelco Dolstra
coerced to a string.
2008-07-23* A quick hack to make nix-prefetch-url support mirror:// URLs. ItEelco Dolstra
requires that $NIXPKGS_ALL points at a Nixpkgs tree.
2008-07-23* Make sure that copy-from-other-stores.pl is built.Eelco Dolstra
2008-07-18* Fix the tests.Eelco Dolstra
2008-07-18* Allow read-only access to the store (e.g., non-root users on NixOSEelco Dolstra
can do operations like "nix-store -qR <path>" even without the Nix daemon).
2008-07-18* Use the copy-from-other-stores substituter by default. Of course,Eelco Dolstra
it only does something if $NIX_OTHER_STORES (not really a good name...) is set. * Do globbing on the elements of $NIX_OTHER_STORES. E.g. you could set it to /mnts/*/nix or something. * Install substituters in libexec/nix/substituters.
2008-07-12* Quick prototype of a substituter that copies paths from other NixEelco Dolstra
stores (typically remote Nix stores mounted via e.g. NFS, or the Nix store on the NixOS installation CD). Example use: $ sshfs foo@example.org:/ /mnt $ NIX_OTHER_STORES=/mnt/nix \ NIX_SUBSTITUTERS=.../copy-from-other-stores.pl \ nix-env -i foo This will be especially useful for the installation CD since it doesn't require a manifest for the CD contents.
2008-07-11* Generalised the dependencyClosure primop to builtins.genericClosure,Eelco Dolstra
which is hopefully more useful. * New primops: length, mul, div.
2008-07-01* Export the nix-env derivation name parsing and version comparisonEelco Dolstra
logic through the `parseDrvName' and `compareVersions' primops. This will allow expressions to easily check whether some dependency is a specific needed version or falls in some version range. See tests/lang/eval-okay-versions.nix for examples.
2008-06-23* `make ext-clean': remove the bzip2 build.Eelco Dolstra
