Eelco Dolstra 8fce03e0ad * nix-store --verify: repair bad hash fields in the metadata file. 2008-12-16 13:28:18 +00:00
Eelco Dolstra 60ec75048a * Pass --use-atime / --max-atime to the daemon. 2008-12-16 12:23:35 +00:00
Eelco Dolstra 6f6bb1fdea * Delete the chroot if it already exists (e.g. left over from an
interrupted build).
2008-12-15 23:55:11 +00:00
Eelco Dolstra 92cb7c4dfe * Put chroots in the Nix store. This ensures that we can create hard
links to the inputs.
2008-12-12 17:14:57 +00:00
Eelco Dolstra 0008b0006d * Simplify deleting .lock files in /nix/store: just don't delete them
if they belong a path that's currently being built.  This gets rid
  of some Cygwin-specific code.
2008-12-12 17:03:18 +00:00
Eelco Dolstra ac36c6cd44 * Some hackery to make "make check" succeed on Cygwin. 2008-12-12 15:36:18 +00:00
Eelco Dolstra 2b70a8e7c9 * Detect whether unshare() is available. 2008-12-12 13:41:36 +00:00
Eelco Dolstra 9122dcecbb * We can't use string objects in signal handlers because they might
allocate memory, which is verboten in signal handlers.  This caused
  random failures in the test suite on Mac OS X (triggered by the spurious
  SIGPOLL signals on Mac OS X, which should also be fixed).
2008-12-12 12:59:27 +00:00
Eelco Dolstra 6776a52bb3 * Use a PathSet for the chroot directories so that we don't
accidentally bind-mount a directory twice.
2008-12-12 11:49:42 +00:00
Eelco Dolstra d86bd22d24 * Define _GNU_SOURCE. Hopefully this fixes the build on Debian 4.0
(http://hydra.nixos.org/nixlog/384/1).
2008-12-12 10:20:19 +00:00
Eelco Dolstra ac5478eb52 * Don't provide the whole Nix store in the chroot, but only the
closure of the inputs.  This really enforces that there can't be any
  undeclared dependencies on paths in the store.  This is done by
  creating a fake Nix store and creating bind-mounts or hard-links in
  the fake store for all paths in the closure.  After the build, the
  build output is moved from the fake store to the real store.  TODO:
  the chroot has to be on the same filesystem as the Nix store for
  this to work, but this isn't enforced yet.  (I.e. it only works
  currently if /tmp is on the same FS as /nix/store.)
2008-12-11 18:57:10 +00:00
Eelco Dolstra 652817046b * Revert r13150: now that we use private namespaces for the chroot, we
don't have to put the chroot in /nix/var/nix/chroots anymore.
  They're back in /tmp now.
2008-12-11 17:52:34 +00:00
Eelco Dolstra 5a569509b4 * Provide a minimal /etc/passwd in the chroot to keep some builders
happy.
2008-12-11 17:44:02 +00:00
Eelco Dolstra 7c54f1603f * Do chroot builds in a private namespace. This means that all the
bind-mounts we do are only visible to the builder process and its
  children.  So accidentally doing "rm -rf" on the chroot directory
  won't wipe out /nix/store and other bind-mounted directories
  anymore.  Also, the bind-mounts in the private namespace disappear
  automatically when the builder exits.
2008-12-11 17:00:12 +00:00
Eelco Dolstra 07cdfb09fb * Open the connection to the daemon lazily (on demand) so that
read-only operations (like nix-env -qa) work properly when the
  daemon isn't running.
2008-12-11 14:30:25 +00:00
Eelco Dolstra a0766eca27 * Build on Debian 4.0 (GCC 4.1.1). 2008-12-04 21:07:29 +00:00
Eelco Dolstra cd16d5dc3d * Doh. 2008-12-04 17:56:12 +00:00
Eelco Dolstra 5b949241a5 * Build some 64-bit RPMs/Debs. 2008-12-04 17:54:14 +00:00
Eelco Dolstra 67958f21df * Be sure to clean up the daemon if the test fails. 2008-12-04 16:55:22 +00:00
Eelco Dolstra d91dc086bb 2008-12-04 16:51:36 +00:00
Eelco Dolstra 9ac3f5df9c * Propagate --max-silent-time to remote machines. 2008-12-04 16:51:16 +00:00
Eelco Dolstra bcfe98acff * Prefer building on a remote machine over a local machine. This
makes more sense for the build farm, otherwise every nix-store
  invocation will lead to at least one local build.  Will come up with
  a better solution later...
2008-12-04 16:35:47 +00:00
Eelco Dolstra 9850262a72 * Build RPMs, Debs, coverage analysis. 2008-12-04 15:25:28 +00:00
Eelco Dolstra 909fbb9de1 * When using build hooks, for any nix-store -r build operation, it is
necessary that at least one build hook doesn't return "postpone",
  otherwise nix-store will barf ("waiting for a build slot, yet there
  are no running children").  So inform the build hook when this is
  the case, so that it can start a build even when that would exceed
  the maximum load on a machine.
2008-12-04 14:29:41 +00:00
Eelco Dolstra 5dfba0b4db * Force allocation of a pseudo-terminal to clean up the remote
nix-store process when the connection is interrupted.
2008-12-04 13:36:52 +00:00
Eelco Dolstra 9ccdb80de3 * Don't ignore errors from writing to stderr. That way, when
nix-store -r (or some other operation) is started via ssh, it will
  at least have a chance of terminating quickly when the connection is
  killed.  Right now it just runs to completion, because it never
  notices that stderr is no longer connected to anything.  Of course
  it would be better if sshd would just send a SIGHUP, but it doesn't
  (https://bugzilla.mindrot.org/show_bug.cgi?id=396).
2008-12-04 13:13:31 +00:00
Eelco Dolstra 9fd9c4c635 * Support multiple system types per remote machine, e.g. a machine
list like

    root@example.org x86_64-linux /root/.ssh/id_buildfarm 1
    root@example.org i686-darwin  /root/.ssh/id_buildfarm 1

  This is possible when the Nix installation on example.org itself has
  remote builds enabled.

Eelco Dolstra f8713e1287 * Dirty hack to make nix-push work properly on derivations: the
derivation should be a source rather than a derivation dependency of
  the call to the NAR derivation.  Otherwise the derivation (and all
  its dependencies) will be built as a side-effect, which may not even
  succeed.
2008-12-04 10:40:41 +00:00
Eelco Dolstra 82ae85de27 * addToStore() in nix-worker: don't write the NAR dump received from
the client to a temporary directory, as that is highly inefficient.
2008-12-03 18:05:14 +00:00
Eelco Dolstra 5eaf644c99 * A simple API for parsing NAR archives. 2008-12-03 17:30:32 +00:00
Eelco Dolstra cdee317419 * Backwards compatibility. 2008-12-03 17:02:29 +00:00
Eelco Dolstra d95b68fde3 2008-12-03 16:15:38 +00:00
Eelco Dolstra ff762fb499 * Pass HashType values instead of strings. 2008-12-03 16:10:17 +00:00
Eelco Dolstra 1307b22223 * Made addToStore() a lot more efficient: it no longer reads the path
being copied 3 times in the worst case.  It doesn't run in constant space,
  but it didn't do that anyway.
2008-12-03 15:51:17 +00:00
Eelco Dolstra 64519cfd65 * Unify the treatment of sources copied to the store, and recursive
SHA-256 outputs of fixed-output derivations.  I.e. they now produce
  the same store path:

  $ nix-store --add x
  /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x

  $ nix-store --add-fixed --recursive sha256 x
  /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x

  the latter being the same as the path that a derivation

    derivation {
      name = "x";
      outputHashAlgo = "sha256";
      outputHashMode = "recursive";
      outputHash = "...";
      ...
    };

  produces.

  This does change the output path for such fixed-output derivations.
  Fortunately they are quite rare.  The most common use is fetchsvn
  calls with SHA-256 hashes.  (There are a handful of those is
  Nixpkgs, mostly unstable development packages.)
  
* Documented the computation of store paths (in store-api.cc).
2008-12-03 15:06:30 +00:00
Eelco Dolstra 09bc0c502c * Install the release notes. 2008-11-29 00:31:39 +00:00
Eelco Dolstra 5d4eb9dd07 * Moved the build farm job for building Nix to the Nix tree. 2008-11-26 01:13:29 +00:00
Eelco Dolstra 0c478d2f4d * Ignore carriage returns. 2008-11-25 02:30:35 +00:00
Eelco Dolstra 5024bde8f4 * Handle prematurely ended logfiles, i.e. make sure we emit enough
close tags.
2008-11-25 01:06:15 +00:00
Eelco Dolstra 2ab09a55cf * Bump the version number. 2008-11-20 21:51:58 +00:00

Eelco Dolstra eb86b6f5a5 2008-11-20 15:08:39 +00:00
Eelco Dolstra 3d2035ea86 * Blindly doing a replacement of occurences of $bindir (when running
the tests) is a bad idea when $bindir = /usr and some programs (like
  perl) live there.  Fortunately it doesn't seem to be needed anymore.
2008-11-20 15:08:34 +00:00
Eelco Dolstra 285d26374a * Don't set the prefix to /nix by default, rather use the Autoconf
default of /usr/local.  However, localstatedir and storedir are set
  to /nix/var/nix and /nix/store respectively unless they're
  explicitly overriden.
