2012-07-26 Merge branch 'master' into no-manifestsEelco Dolstra11-58/+35
2012-07-25 prim_import: When importing .drvs, allocate the intermediate attrset on the ↵Shea Levy1-1/+1
heap just in case it escapes the stack frame.
2012-07-25 import: If the path is a valid .drv file, parse it and generate a derivation ↵Shea Levy1-1/+25
attrset. The generated attrset has drvPath and outPath with the right string context, type 'derivation', outputName with the right name, all with a list of outputs, and an attribute for each output. I see three uses for this (though certainly there may be more): * Using derivations generated by something besides nix-instantiate (e.g. guix) * Allowing packages provided by channels to be used in nix expressions. If a channel installed a valid deriver for each package it provides into the store, then those could be imported and used as dependencies or installed in environment.systemPackages, for example. * Enable hydra to be consistent in how it treats inputs that are outputs of another build. Right now, if an input is passed as an argument to the job, it is passed as a derivation, but if it is accessed via NIX_PATH (i.e. through the <> syntax), then it is a path that can be imported. This is problematic because the build being depended upon may have been built with non-obvious arguments passed to its jobset file. With this feature, hydra can just set the name of that input to the path to its drv file in NIX_PATH

2012-07-09 prim_import(): prefetch substitute info in parallel using queryMissing()Eelco Dolstra1-0/+6
2012-06-27 nix-store -r: do substitutions in parallelEelco Dolstra1-1/+1
I.e. when multiple non-derivation arguments are passed to ‘nix-store -r’ to be substituted, do them in parallel.
2012-04-13 Use Bison 2.5Eelco Dolstra1-0/+2
2012-03-05 Fix compilation on FreeBSDEelco Dolstra2-0/+2
http://hydra.nixos.org/build/2213576 Not sure why compilation doesn't fail on other platforms...
2012-02-09 Fix error messageEelco Dolstra1-3/+4
This fixes the error message error: file `' was not found in the Nix search path (add it using $NIX_PATH or -I)
2012-02-04 * Inline some functions and get rid of the indirection throughEelco Dolstra6-116/+93
EvalState::eval(). This gives a 12% speedup on ‘nix-instantiate /etc/nixos/nixos/ -A system --readonly-mode’ (from 1.01s to 0.89s).
2012-02-04 * Print elapsed evaluation time.Eelco Dolstra1-1/+9
2012-01-26 * Fix importing a derivation. This gave a segfault.Eelco Dolstra1-8/+23
2012-01-19 * Allow comparisons between derivations by comparing the outPathEelco Dolstra1-2/+14
attributes.
2012-01-19 * Add some debug output to print the derivation name once it's known.Eelco Dolstra1-1/+4
This makes it easier to pinpoint the source of a crash.
2012-01-07 * Don't create thunks for simple constants (integers, strings, paths)Eelco Dolstra5-133/+193
and allocate them only once. * Move Value and related functions into value.hh.
2012-01-04 * Remove dead code.Eelco Dolstra2-4/+0
2012-01-04 * Don't use dynamic_cast, it's very slow. "nix-instantiateEelco Dolstra3-24/+23
/etc/nixos/nixos -A system" spent about 10% of its time in dynamic_cast.
2012-01-03 * Drop the inefficient "Path" suffix in output attribute names.Eelco Dolstra1-3/+1
2012-01-03 * Move the implementation of the ‘derivation’ primop into a separateEelco Dolstra2-25/+3
file.
2011-12-21 * The ‘foo.drvPath’ feature was already broken in read-only mode.Eelco Dolstra1-1/+2
Since it's rarely used and fixing it is too much work right now, just document it.
2011-12-21 * Simplify the context handling logic.Eelco Dolstra1-24/+13
2011-12-16 * Sync with the trunk.Eelco Dolstra3-14/+16
2011-12-02 * Move parseHash16or32 into libutil, and use in nix-hash.Eelco Dolstra1-11/+1
2011-12-01 * Allow '<nixexpr>' syntax to be used in nix-instantiate, nix-buildEelco Dolstra2-0/+13
and nix-env, e.g., $ nix-env -f '<nixpkgs>' -i patchelf or $ nix-build '<nixos/tests>' -A login.test

2011-11-06 Embed output name into the context of the *OutPath attributes and extract it ↵Shea Levy1-2/+9
for input derivations Multiple outputs test passes!
2011-11-06 Include all outputs of derivations in the closure of explicitly-passed ↵Shea Levy1-2/+8
derivation paths This required adding a queryOutputDerivationNames function in the store API
2011-11-06 The 'insert output between = signs' approach was not helpfulShea Levy1-9/+2
2011-11-06 Merge from trunkShea Levy1-3/+6
2011-10-27 * In printValueAsXML, handle the case where a "type" attribute is notEelco Dolstra1-3/+6
a string. This happens in the NixOS option system. * Remove a bogus comparison of a unsigned integer with -1.
2011-09-16 Remove the current output metadata from the string for ↵Shea Levy1-1/+8
unsaveDiscardOutputDependency
2011-09-16 Add information about which output is active to drvPath's contextShea Levy1-4/+6
This will break things that depend on being able to just strip away an equals sign, so those have to be updated next
2011-09-16 Add an sCurrentOutput member to EvalStateShea Levy2-1/+2
2011-09-16 Add a currentOutput attribute to derivations keep track of which output is ↵Shea Levy1-1/+4
active
2011-09-14 First attempt at the output-as-derivation semanticsShea Levy1-9/+27
For each output, this adds a corresponding attribute to the derivation that is the same as the derivation except for outPath, which is set to the path specific to that output. Additionally, an "all" attribute is added that is a list of all of the output derivations. This has to be done outside of derivationStrict as each output is itself a derivation that contains itself (and all other outputs) as an attribute. The derivation itself is equivalent to the first output in the outputs list (or "out" if that list isn't set).
2011-08-31 * Eliminate all uses of the global variable ‘store’ from libstore.Eelco Dolstra1-4/+4
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 * Cache the result of file evaluation (i.e, memoize evalFile()). ThisEelco Dolstra2-11/+22
prevents files from being evaluated and stored as values multiple times. For instance, evaluation of the ‘system’ attribute in NixOS causes ‘nixpkgs/pkgs/lib/lists.nix’ to be evaluated 2019 times. Caching gives a modest speedup and a decent memory footprint reduction (e.g., from 1.44s to 1.28s, and from 81 MiB to 59 MiB with GC_INITIAL_HEAP_SIZE=100000 on my system).
2011-08-06 * Handle the case where the search path element is a regular file.Eelco Dolstra1-1/+2
2011-08-06 * Remove a debug statement.Eelco Dolstra1-1/+0
2011-08-06 * Add the Nix corepkgs to the end of the search path. This makes itEelco Dolstra1-0/+2
possible for other Nix expressions to use corepkgs (mostly useful for the buildenv function).
2011-08-06 * Allow redirections in search path entries. E.g. if you have aEelco Dolstra2-6/+25
directory /home/eelco/src/stdenv-updates that you want to use as the directory for import such as with (import <nixpkgs> { }); then you can say $ nix-build -I nixpkgs=/home/eelco/src/stdenv-updates
2011-08-06 * Add a Nix expression search path feature. Paths between angleEelco Dolstra6-6/+72
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 Dolstra7-42/+30
the EvalState class.
