2008-08-25 * Strip off the `.nix' suffix from the attribute name for files inEelco Dolstra5-6/+27
~/.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.
2008-08-14 Fixing an obvious typo in override code. I do not know whether it works ↵Michael Raskin1-1/+1
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 Dolstra2-2/+25
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 Dolstra7-18/+37
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 Dolstra5-46/+74
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 Dolstra7-135/+165
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 Dolstra1-4/+0
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 Dolstra5-70/+18
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 * `nix-env --set': support --dry-run.Eelco Dolstra1-3/+10
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 * 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 * Make nix-env --dry-run print the paths to be substituted correctlyEelco Dolstra10-180/+211
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.
2008-07-18 * Allow read-only access to the store (e.g., non-root users on NixOSEelco Dolstra1-5/+9
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 Dolstra1-3/+4
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.
2008-07-11 * Generalised the dependencyClosure primop to builtins.genericClosure,Eelco Dolstra1-137/+55
which is hopefully more useful. * New primops: length, mul, div.
2008-07-01 * Export the nix-env derivation name parsing and version comparisonEelco Dolstra5-37/+54
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.
2008-06-18 (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.
2008-06-14 * 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
2008-06-13 * 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
2008-06-09 * Merged the no-bdb branch (-r10900:HEADEelco Dolstra17-691/+786
https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
2008-06-04 First attempt to update Nix SDF grammar to match the actual bison grammarSander van der Burg1-2/+4
2008-05-21 * GCC 4.3.0 (Fedora 9) compatibility fixes. Reported by Gour andEelco Dolstra11-3/+18
Armijn Hemel.
2008-04-09 * sockaddr_un doesn't allow path names of more than 108 characters.Eelco Dolstra2-6/+26
This isn't usually a problem, except that it causes tests to fail when performed in a directory with a very long path name. So chdir to the socket directory and use a relative path name.
2008-03-27 * Use /tmp/nix-build-<drvpath>-<counter> instead ofEelco Dolstra3-8/+17
/tmp/nix-<pid>-<counter> for temporary build directories. This increases purity a bit: many packages store the temporary build path in their output, causing (generally unimportant) binary differences.
2008-03-20 * Disable the don't-run-as-root sanity check because it breaks RPMEelco Dolstra1-0/+2
builds (which are done as root...).
2008-03-20 * Note that the SDF grammar isn't used.Eelco Dolstra1-0/+3
2008-03-01 * A transaction is unnecessary since the path cannot beEelco Dolstra1-8/+3
garbage-collected (it's a temporary root).
2008-02-21 * checkVarDefs: don't check in closed terms, which don't haveEelco Dolstra1-1/+5
undefined variables by definition. This matters for the implementation of "with", which does a call to checkVarDefs to see if the body of the with has no undefined variables. (It can't be checked at parse time because you don't know which variables are in the "with" attribute set.) If we check closed terms, then we check not just the with body but also the substituted terms, which are typically very large. This is the cause of the poor nix-env performance on Nixpkgs lately. It didn't happen earlier because "with" wasn't used very often in the past. This fix improves nix-env performance roughly 60x on current Nixpkgs. nix-env -qa is down from 29.3s to 0.5s on my laptop, and nix-env -qa --out-path is down from 229s to 3.39s. Not bad for a 1-line fix :-)
2008-02-05 * Fix the parsing ofEelco Dolstra1-1/+5
'' '${foo}' '' where the antiquote should work as expected, instead of giving the string "'${foo}'".
2008-01-29 * nix-store --dump-db / --load-db to dump/load the Nix DB.Eelco Dolstra8-137/+117
* nix-store --register-validity: option to supply the content hash of each path. * Removed compatibility with Nix <= 0.7 stores.
