2013-10-02 Fix segfault in nix-repl / hydra-eval-jobsEelco Dolstra1-3/+3
If a "with" attribute set fails to evaluate, we have to make sure its Env record remains unchanged. Otherwise, repeated evaluation gives a segfault: nix-repl> :a with 0; { a = x; b = x; } Added 2 variables. nix-repl> a error: value is an integer while an attribute set was expected nix-repl> b Segmentation fault

2013-09-18 build-remote.pl: Don't use substituters on the remoteEelco Dolstra1-1/+1
It's kinda pointless to check substituters on the remote side, since we just checked them locally.
2013-09-17 RestoreSink: Slightly reduce the number of concurrent FDsEelco Dolstra1-0/+1
2013-09-10 Version was called 1.6, not 1.6.0Eelco Dolstra1-1/+1

2013-09-06 Don't apply the CPU affinity hack to nix-shell (and other Perl programs)Eelco Dolstra5-7/+11
As discovered by Todd Veldhuizen, the shell started by nix-shell has its affinity set to a single CPU. This is because nix-shell connects to the Nix daemon, which causes the affinity hack to be applied. So we turn this off for Perl programs.

2013-09-06 nix-shell: Support a .drv as argumentEelco Dolstra1-8/+13
Fixes #161.
2013-09-03 nix-env -i: Add a flag ‘--remove-all’ / ‘-r’Eelco Dolstra2-17/+39
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.
2013-09-03 nix-env: Use wildcard match by defaultEelco Dolstra2-13/+8
That is, you don't need to pass '*' anymore, so nix-env -qa is equivalent to nix-env -qa '*'
2013-09-03 nix-env: Load files in ~/.nix-defexpr on demandEelco Dolstra3-3/+18
So if you do "nix-env -qa -A nixos", then other channels won't be parsed/evaluated at all.
2013-09-03 Check for name collisions in the input Nix expressionsEelco Dolstra1-3/+9
2013-09-03 Work on Values instead of ExprsEelco Dolstra4-50/+62
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).
2013-09-03 ReformatEelco Dolstra1-33/+35
2013-09-03 Get rid of the parse tree cacheEelco Dolstra6-34/+35
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.
2013-09-02 Add some support code for nix-replEelco Dolstra3-12/+26

Issue #162.
2013-09-02 Fix manual errorEelco Dolstra1-1/+1
Reported by Matija Šuklje. Fixes #163.

2013-09-02 Add an option to limit the log output of buildersEelco Dolstra4-0/+34
This is mostly useful for Hydra to deal with builders that get stuck in an infinite loop writing data to stdout/stderr.
2013-08-26 Simplify inherited attribute handlingShea Levy7-38/+46
This reduces the difference between inherited and non-inherited attribute handling to the choice of which env to use (in recs and lets) by setting the AttrDef::e to a new ExprVar in the parser rather than carrying a separate AttrDef::v VarRef member. As an added bonus, this allows inherited attributes that inherit from a with to delay forcing evaluation of the with's attributes. Signed-off-by: Shea Levy <shea@shealevy.com>

2013-08-26 Fix personality switching from x86_64 to i686Gergely Risko1-1/+6
On Linux, Nix can build i686 packages even on x86_64 systems. It's not enough to recognize this situation by settings.thisSystem, we also have to consult uname(). E.g. we can be running on a i686 Debian with an amd64 kernel. In that situation settings.thisSystem is i686-linux, but we still need to change personality to i686 to make builds consistent.
2013-08-23 Manual: Don't use actual hashes of Nix dependenciesEelco Dolstra1-2/+2
These cause an unnecessary runtime dependency :-)
2013-08-21 Fix corrupt PNGEelco Dolstra1-0/+0
Libpng used to accept this, but no longer does.

2013-08-19 Store Nix integers as longsEelco Dolstra9-23/+25
So on 64-bit systems, integers are now 64-bit. Fixes #158.

2013-08-14 corepkgs/nar.nix: Prefer local buildsShea Levy1-0/+3
nar.nix's builder depends on coreutils and nix itself being in $PATH. Unfortunately, there's no good way to ensure that these packages exist in the same place on the remote machine: The local machine may have nix installed in /usr, and the remote machine in /usr/local, but the generated nar.sh builder will refer to /usr and thus fail on the remote machine. This ensures that nar.sh is run on the same machine that instantiates it. Signed-off-by: Shea Levy <shea@shealevy.com>

2013-08-07 Run the daemon worker on the same CPU as the clientEelco Dolstra9-4/+92
On a system with multiple CPUs, running Nix operations through the daemon is significantly slower than "direct" mode: $ NIX_REMOTE= nix-instantiate '<nixos>' -A system real 0m0.974s user 0m0.875s sys 0m0.088s $ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system real 0m2.118s user 0m1.463s sys 0m0.218s The main reason seems to be that the client and the worker get moved to a different CPU after every call to the worker. This patch adds a hack to lock them to the same CPU. With this, the overhead of going through the daemon is very small: $ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system real 0m1.074s user 0m0.809s sys 0m0.098s

This allows saying "-1" instead of "builtins.sub 0 1".
