2008-08-14 * Added an experimental feature suggested by Andres: ellipses ("...")Eelco Dolstra14-23/+57
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 Dolstra2-1/+2
when upgrading Nix.
2008-08-14 * @-patterns as in Haskell. For instance, in a function definitionEelco Dolstra10-46/+106
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 Dolstra1-5/+8
2008-08-14 * Refactoring: combine functions that take an attribute set andEelco Dolstra12-145/+181
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 Dolstra4-16/+17
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 Dolstra13-104/+22
2008-08-06 Updates to nix-reduce-buildMichael Raskin1-26/+50
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 Dolstra2-162/+22
* Updated the release notes.
2008-08-05 * Better error checking of the data from the substituters.Eelco Dolstra1-21/+16
2008-08-04 * Use optimistic profile locking for nix-env operations like `-i' andEelco Dolstra1-138/+163
`-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 Dolstra2-0/+2
2008-08-04 * `nix-env --set': support --dry-run.Eelco Dolstra1-3/+10
2008-08-04 * nix-build: `--dry-run' flag.Eelco Dolstra1-0/+9
2008-08-04 * `nix-store --realise': print what paths will be built/downloaded,Eelco Dolstra4-37/+50
just like nix-env. * `nix-store --realise': --dry-run option.
2008-08-04 * Doh.Eelco Dolstra2-0/+3
2008-08-04 * build.cc: only use a substituter if it returns info for a path.Eelco Dolstra3-51/+57
2008-08-04 * Always show what paths we're going to build/download (as inEelco Dolstra1-9/+7
--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 Dolstra4-5/+15
downloads.
2008-08-04 * querySubstitutablePathInfo: work properly when run via the daemon.Eelco Dolstra7-16/+49
* --dry-run: print the paths that we don't know how to build/substitute.
2008-08-02 Updates to nix-reduce-build: only realize fixed derivations if user asks so, ↵Michael Raskin1-1/+32
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 Dolstra14-263/+329
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 Dolstra1-3/+10
coerced to a string.
2008-07-23 * A quick hack to make nix-prefetch-url support mirror:// URLs. ItEelco Dolstra1-0/+22
requires that $NIXPKGS_ALL points at a Nixpkgs tree.
2008-07-23 * Make sure that copy-from-other-stores.pl is built.Eelco Dolstra1-1/+2
2008-07-18 * Fix the tests.Eelco Dolstra1-0/+6
2008-07-18 * Allow read-only access to the store (e.g., non-root users on NixOSEelco Dolstra2-6/+11
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 Dolstra3-12/+20
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 Dolstra2-1/+84
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 Dolstra5-139/+442
which is hopefully more useful. * New primops: length, mul, div.
2008-07-01 * Export the nix-env derivation name parsing and version comparisonEelco Dolstra9-37/+103
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 Dolstra1-1/+1
2008-06-18 (no commit message)Eelco Dolstra1-1/+1
2008-06-18 * --max-freed: support values >= 4 GB.Eelco Dolstra4-3/+12
2008-06-18 * Garbage collector: option `--max-freed' to stop after at least NEelco Dolstra6-12/+47
bytes have been freed, `--max-links' to stop when the Nix store directory has fewer than N hard links (the latter being important for very large Nix stores on filesystems with a 32000 subdirectories limit).
2008-06-18 * `nix-store --optimise': handle files with >= 32000 hard links.Eelco Dolstra1-6/+31
(There can easily be more than 32000 occurrences of the empty file.)
2008-06-18 * Some refactoring: put the GC options / results in separate structs.Eelco Dolstra15-166/+252
* The garbage collector now also prints the number of blocks freed.
2008-06-17 * Use bzip2 1.0.5.Eelco Dolstra1-3/+3
2008-06-15 * Test instrumentation.Eelco Dolstra1-0/+1
2008-06-14 * nix-worker: clean up the temporary root for the worker processes Eelco Dolstra3-9/+13
in /nix/var/nix/temproots.
2008-06-14 * Note.Eelco Dolstra1-1/+5
2008-06-14 Also trying to build derivers in case we cannot get substitutersMichael Raskin1-1/+9
2008-06-14 Added local best-effort builds (i.e. one failure does not ruin all packages ↵Michael Raskin2-3/+17
you would like to see built)
2008-06-13 * Garbage collector: don't do a complete topological sort of the NixEelco Dolstra2-74/+87
store under the reference relation, since that means that the garbage collector will need a long time to start deleting paths. Instead just delete the referrers of a path first.
2008-06-13 * Print some progress info during the early GC stages.Eelco Dolstra2-1/+9
2008-06-13 Stupid error in scriptMichael Raskin1-1/+1
2008-06-13 OK, I will believe that fix does no worse..Michael Raskin1-1/+1
2008-06-12 Updated help textMichael Raskin1-6/+15
2008-06-12 Added verbosity for nix-reduce-buildMichael Raskin1-0/+3
2008-06-11 * Updated some URLs.Eelco Dolstra4-17/+19
