2014-08-01Make readDirectory() return inode / file typeEelco Dolstra
2014-06-02nix-env -qa --json: Generate valid JSON even if there are invalid meta attrsEelco Dolstra

Also fixes #261.
2014-04-15nix-env: Minor change to '--delete-generations Nd' semanticsRicardo M. Correia
The option '--delete-generations Nd' deletes all generations older than N days. However, most likely the user does not want to delete the generation that was active N days ago. For example, say that you have these 3 generations: 1: <30 days ago> 2: <15 days ago> 3: <1 hour ago> If you do --delete-generations 7d (say, as part of a cron job), most likely you still want to keep generation 2, i.e. the generation that was active 7 days ago (and for most of the past 7 days, in fact). This patch fixes this issue. Note that this also affects 'nix-collect-garbage --delete-older-than Nd'. Thanks to @roconnor for noticing the issue!
2014-03-30nix-env: Add support for --delete-generations 15dRicardo M. Correia
It will delete all generations older than the specified number of days.
2014-02-18Add a flag ‘--check’ to verify build determinismEelco Dolstra
The flag ‘--check’ to ‘nix-store -r’ or ‘nix-build’ will cause Nix to redo the build of a derivation whose output paths are already valid. If the new output differs from the original output, an error is printed. This makes it easier to test if a build is deterministic. (Obviously this cannot catch all sources of non-determinism, but it catches the most common one, namely the current time.) For example: $ nix-build '<nixpkgs>' -A patchelf ... $ nix-build '<nixpkgs>' -A patchelf --check error: derivation `/nix/store/1ipvxsdnbhl1rw6siz6x92s7sc8nwkkb-patchelf-0.6' may not be deterministic: hash mismatch in output `/nix/store/4pc1dmw5xkwmc6q3gdc9i5nbjl4dkjpp-patchelf-0.6.drv' The --check build fails if not all outputs are valid. Thus the first call to nix-build is necessary to ensure that all outputs are valid. The current outputs are left untouched: the new outputs are either put in a chroot or diverted to a different location in the store using hash rewriting.
2014-01-21Remove unused typeEelco Dolstra
2013-12-20nix-env --set-flag: Barf if a selector doesn't match any installed packageEelco Dolstra
Fixes #184.
2013-11-19Check meta values and warn about bad onesEelco Dolstra
2013-11-19Generalise meta attributesEelco Dolstra
2013-11-19nix-env -q: Add a --json flagEelco Dolstra
2013-10-24Rename "attribute sets" to "sets"Eelco Dolstra
We don't have any other kind of sets so calling them attribute sets is unnecessarily verbose.
2013-09-06Remove stray debug lineEelco Dolstra
2013-09-03nix-env -i: Add a flag ‘--remove-all’ / ‘-r’Eelco Dolstra
This is equivalent to running ‘nix-env -e '*'’ first, except that it happens in a single transaction. Thus, ‘nix-env -i pkgs...’ replaces the profile with the specified set of packages. The main motivation is to support declarative package management (similar to environment.systemPackages in NixOS). That is, if you have a specification ‘profile.nix’ like this: with import <nixpkgs> {}; [ thunderbird geeqie ... ] then after any change to ‘profile.nix’, you can run: $ nix-env -f profile.nix -ir to update the profile to match the specification. (Without the ‘-r’ flag, if you remove a package from ‘profile.nix’, it won't be removed from the actual profile.) Suggested by @zefhemel.
2013-09-03nix-env: Use wildcard match by defaultEelco Dolstra
That is, you don't need to pass '*' anymore, so nix-env -qa is equivalent to nix-env -qa '*'
2013-09-03nix-env: Load files in ~/.nix-defexpr on demandEelco Dolstra
So if you do "nix-env -qa -A nixos", then other channels won't be parsed/evaluated at all.
2013-09-03Check for name collisions in the input Nix expressionsEelco Dolstra
2013-09-03Work on Values instead of ExprsEelco Dolstra
This prevents some duplicate evaluation in nix-env and nix-instantiate. Also, when traversing ~/.nix-defexpr, only read regular files with the extension .nix. Previously it was reading files like .../channels/binary-caches/<name>. The only reason this didn't cause problems is pure luck (namely, <name> shadows an actual Nix expression, the binary-caches files happen to be syntactically valid Nix expressions, and we iterate over the directory contents in just the right order).
2013-09-03Get rid of the parse tree cacheEelco Dolstra
Since we already cache files in normal form (fileEvalCache), caching parse trees is redundant. Note that getting rid of this cache doesn't actually save much memory at the moment, because parse trees are currently not freed / GC'ed.
2013-08-26Fix typos, especially those that end up in the Nix manualIvan Kozik
2012-12-12Allow setting the profile location using $NIX_PROFILEEelco Dolstra
Fixes #69.
2012-12-03Fix the ‘--prebuilt-only’ flagEelco Dolstra
2012-12-03WhitespaceEelco Dolstra
2012-11-28nix-env -q --out-path: Support multiple outputsEelco Dolstra
We now print all output paths of a package, e.g. openssl-1.0.0i bin=/nix/store/gq2mvh0wb9l90djvsagln3aqywqmr6vl-openssl-1.0.0i-bin;man=/nix/store/7zwf5r5hsdarl3n86dasvb4chm2xzw9n-openssl-1.0.0i-man;/nix/store/cj7xvk7fjp9q887359j75pw3pzjfmqf1-openssl-1.0.0i or (in XML mode) <item attrPath="openssl" name="openssl-1.0.0i" system="x86_64-linux"> <output name="bin" path="/nix/store/gq2mvh0wb9l90djvsagln3aqywqmr6vl-openssl-1.0.0i-bin" /> <output name="man" path="/nix/store/7zwf5r5hsdarl3n86dasvb4chm2xzw9n-openssl-1.0.0i-man" /> <output name="out" path="/nix/store/cj7xvk7fjp9q887359j75pw3pzjfmqf1-openssl-1.0.0i" /> </item>
2012-10-04getDerivation(): Don't always quietly ignore assertion failureEelco Dolstra
Ignoring assertion failures makes some sense for nix-env -qa, but not for nix-instantiate/nix-build or hydra-eval-jobs.
2012-10-03When ‘--help’ is given, just run ‘man’ to show the manual pageEelco Dolstra
I.e. do what git does. I'm too lazy to keep the builtin help text up to date :-) Also add ‘--help’ to various commands that lacked it (e.g. nix-collect-garbage).
2012-10-03nix-env: Support ‘--repair’ flagEelco Dolstra
2012-09-13nix-env --delete-generations: Support --dry-run flagEelco Dolstra
Fixes #43.
2012-08-01nix-env: Ignore manifest.nix when recursing into ~/.nix-defexprEelco Dolstra
Channels are implemented using a profile now, and profiles contain a manifest.nix file. This should be ignored to prevent bogus packages from showing up in nix-env.
2012-07-30Refactor settings processingEelco Dolstra
Put all Nix configuration flags in a Settings object.
2012-07-11Replace hasSubstitutes() with querySubstitutablePaths()Eelco Dolstra
querySubstitutablePaths() takes a set of paths, so this greatly reduces daemon <-> client latency.
2012-07-11Add a function queryValidPaths()Eelco Dolstra
queryValidPaths() combines multiple calls to isValidPath() in one. This matters when using the Nix daemon because it reduces latency. For instance, on "nix-env -qas \*" it reduces execution time from 5.7s to 4.7s (which is indistinguishable from the non-daemon case).
2012-07-11nix-env: Determine which paths have substitutes in parallelEelco Dolstra
2012-06-27nix-store -r: do substitutions in parallelEelco Dolstra
I.e. when multiple non-derivation arguments are passed to ‘nix-store -r’ to be substituted, do them in parallel.
2011-12-01* Allow '<nixexpr>' syntax to be used in nix-instantiate, nix-buildEelco Dolstra
and nix-env, e.g., $ nix-env -f '<nixpkgs>' -i patchelf or $ nix-build '<nixos/tests>' -A login.test
2011-08-31* Eliminate all uses of the global variable ‘store’ from libstore.Eelco Dolstra
This should also fix: nix-instantiate: ./../boost/shared_ptr.hpp:254: T* boost::shared_ptr<T>::operator->() const [with T = nix::StoreAPI]: Assertion `px != 0' failed. which was caused by hashDerivationModulo() calling the ‘store’ object (during store upgrades) before openStore() assigned it.
2011-08-06* Add a Nix expression search path feature. Paths between angleEelco Dolstra
brackets, e.g. import <nixpkgs/pkgs/lib> are resolved by looking them up relative to the elements listed in the search path. This allows us to get rid of hacks like import "${builtins.getEnv "NIXPKGS_ALL"}/pkgs/lib" The search path can be specified through the ‘-I’ command-line flag and through the colon-separated ‘NIX_PATH’ environment variable, e.g., $ nix-build -I /etc/nixos ... If a file is not found in the search path, an error message is lazily thrown.
2011-08-06* Refactoring: move parseExprFromFile() and parseExprFromString() intoEelco Dolstra
the EvalState class.
2011-04-11* `nix-env -ub' (`--prebuilt-only') didn't really work because itEelco Dolstra
checked too soon whether substitutes are available. That is, it did so for every available package, rather than those matching installed packages. This was very slow and subject to assertion failures. So do the check much later. Idem for `nix-env -qab' and `nix-env -ib'.
2010-11-16* Sync with the trunk.Eelco Dolstra
2010-10-24* Keep attribute sets in sorted order to speed up attribute lookups.Eelco Dolstra
* Simplify the representation of attributes in the AST. * Change the behaviour of listToAttrs() in case of duplicate names.
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* Sync with the trunk.Eelco Dolstra
2010-09-14* Doh. Remove debug message.Eelco Dolstra
2010-08-04* Sync with the trunk.Eelco Dolstra
2010-08-04* Set the default system filter to "*". This ensures that (forEelco Dolstra
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.
2010-05-12* Sync with the trunk.Eelco Dolstra
2010-05-06* Store attribute positions in the AST and report duplicate attributeEelco Dolstra
errors with position info. * For all positions, use the position of the first character of the first token, rather than the last character of the first token plus one.
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...)
