2014-12-17Keep only libstore, nix-daemon, and related stuff.Ludovic Courtès
2014-03-28Don't interpret strings as format stringsEelco Dolstra
Ludo reported this error: unexpected Nix daemon error: boost::too_few_args: format-string refered to more arguments than were passed coming from this line: printMsg(lvlError, run.program + ": " + string(err, 0, p)); The problem here is that the string ends up implicitly converted to a Boost format() object, so % characters are treated specially. I always assumed (wrongly) that strings are converted to a format object that outputs the string as-is. Since this assumption appears in several places that may be hard to grep for, I've added some C++ type hackery to ensures that the right thing happens. So you don't have to worry about % in statements like printMsg(lvlError, "foo: " + s); or throw Error("foo: " + s);
2014-03-12Remove unnecessary null pointer checksEelco Dolstra
Fixes #225.
2014-02-27Set up a minimal /dev in chrootsEelco Dolstra
Not bind-mounting the /dev from the host also solves the problem with /dev/shm being a symlink to something not in the chroot.

2013-11-23Use libnix as a prefix for all Nix librariesEelco Dolstra
In particular "libutil" was always a problem because it collides with Glibc's libutil. Even if we install into $(libdir)/nix, the linker sometimes got confused (e.g. if a program links against libstore but not libutil, then ld would report undefined symbols in libstore because it was looking at Glibc's libutil).
2013-11-23Allow (dynamic) libraries to depend on other librariesEelco Dolstra
2013-11-22Support building dynamic librariesEelco Dolstra

2013-11-22New non-recursive, plain Make-based build systemEelco Dolstra
2013-11-14Remove nix-setuid-helperEelco Dolstra
AFAIK, nobody uses it, it's not maintained, and it has no tests.
2013-09-17RestoreSink: Slightly reduce the number of concurrent FDsEelco Dolstra
2013-09-06Don't apply the CPU affinity hack to nix-shell (and other Perl programs)Eelco Dolstra
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.
2013-08-26Fix typos, especially those that end up in the Nix manualIvan Kozik
2013-08-19Store Nix integers as longsEelco Dolstra
So on 64-bit systems, integers are now 64-bit. Fixes #158.

2013-08-07Run the daemon worker on the same CPU as the clientEelco Dolstra
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
2013-07-30killUser: Don't let the child kill itself on AppleShea Levy
The kill(2) in Apple's libc follows POSIX semantics, which means that kill(-1, SIGKILL) will kill the calling process too. Since nix has no way to distinguish between the process successfully killing everything and the process being killed by a rogue builder in that case, it can't safely conclude that killUser was successful. Luckily, the actual kill syscall takes a parameter that determines whether POSIX semantics are followed, so we can call that syscall directly and avoid the issue on Apple.

2013-07-12Garbage collector: Don't follow symlinks arbitrarilyEelco Dolstra
Only indirect roots (symlinks to symlinks to the Nix store) are now supported.
2013-06-20Don't keep "disabled" substituters runningEelco Dolstra
For instance, it's pointless to keep copy-from-other-stores running if there are no other stores, or download-using-manifests if there are no manifests. This also speeds things up because we don't send queries to those substituters.
2013-06-07Process stderr from substituters while doing have/info queriesEelco Dolstra
2013-01-03Remove tabsEelco Dolstra
2013-01-03Clear any immutable bits in the Nix storeEelco Dolstra
Doing this once makes subsequent operations like garbage collecting more efficient since we don't have to call makeMutable() first.
2012-11-26Make "nix-build -A <derivation>.<output>" do the right thingEelco Dolstra
For example, given a derivation with outputs "out", "man" and "bin": $ nix-build -A pkg produces ./result pointing to the "out" output; $ nix-build -A pkg.man produces ./result-man pointing to the "man" output; $ nix-build -A pkg.all produces ./result, ./result-man and ./result-bin; $ nix-build -A pkg.all -A pkg2 produces ./result, ./result-man, ./result-bin and ./result-2.
2012-11-15Don't use std::cerr in a few placesEelco Dolstra
Slightly scared of using std::cerr in a vforked process...
2012-11-15Add some debug codeEelco Dolstra
2012-11-09Use vfork() instead of fork() if availableEelco Dolstra
Hopefully this reduces the chance of hitting ‘unable to fork: Cannot allocate memory’ errors. vfork() is used for everything except starting builders.
2012-11-09Remove some redundant close() callsEelco Dolstra
They are unnecessary because we set the close-on-exec flag.
2012-11-09Remove the quickExit functionEelco Dolstra
2012-10-23If hashes do not match, print them in base-32 for SHA-1/SHA-256Eelco Dolstra
Fixes #57.
2012-10-04XML writer: flush after newlinesEelco Dolstra
This is useful for hydra-eval-jobs.
2012-09-28Handle octal escapes in /proc/self/mountinfoEelco Dolstra
2012-09-19Remove setting of the immutable bitEelco Dolstra
Using the immutable bit is problematic, especially in conjunction with store optimisation. For instance, if the garbage collector deletes a file, it has to clear its immutable bit, but if the file has additional hard links, we can't set the bit afterwards because we don't know the remaining paths. So now that we support having the entire Nix store as a read-only mount, we may as well drop the immutable bit. Unfortunately, we have to keep the code to clear the immutable bit for backwards compatibility.
2012-09-19Templatise tokenizeString()Eelco Dolstra
2012-09-11Include config.h before any other headerEelco Dolstra
"config.h" must be included first, because otherwise the compiler might not see the right value of _FILE_OFFSET_BITS. We've had this before; see 705868a8a96a10f70e629433cfffc2d5cd2703eb. In this case, GCC would compute a different address for ‘settings.useSubstitutes’ in misc.cc because of the off_t in ‘settings’.

2012-08-27Merge branch 'master' into no-manifestsEelco Dolstra
2012-08-20In the chroot, make all mounted filesystems privateEelco Dolstra
This is required on systemd, which mounts filesystems as "shared" subtrees. Changes to shared trees in a private mount namespace are propagated to the outside world, which is bad.
2012-08-12Add some basic profiling support to the evaluatorEelco Dolstra
Setting the environment variable NIX_COUNT_CALLS to 1 enables some basic profiling in the evaluator. It will count calls to functions and primops as well as evaluations of attributes. For example, to see where evaluation of a NixOS configuration spends its time: $ NIX_SHOW_STATS=1 NIX_COUNT_CALLS=1 ./src/nix-instantiate/nix-instantiate '<nixos>' -A system --readonly-mode ... calls to 39 primops: 239532 head 233962 tail 191252 hasAttr ... calls to 1595 functions: 224157 `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/pkgs/lib/lists.nix:17:19' 221767 `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/pkgs/lib/lists.nix:17:14' 221767 `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/pkgs/lib/lists.nix:17:10' ... evaluations of 7088 attributes: 167377 undefined position 132459 `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/pkgs/lib/attrsets.nix:119:41' 47322 `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/pkgs/lib/attrsets.nix:13:21' ...
