041717eda3 * download-using-manifests: don't check the cryptographic hash of
downloaded files; rather, check the hash of the unpacked store
  path.

  When the server produces bzipped NAR archives on demand (like Hydra
  does), the hash of the file is not known in advance; it's streamed
  from the server.  Thus the manifest doesn't contain a hash for the
  bzipped NAR archive.  However, the server does know the hash of the
  *uncompressed* NAR archive (the "NarHash" field), since it's stored
  in the Nix database (nix-store -q --hash /nix/store/bla).  So we use
  that instead for checking the integrity of the download.

824b154ce8 * Release output locks as soon as possible, not when the destructor of
the DerivationGoal runs.  Otherwise, if a goal is a top-level goal,
  then the lock won't be released until nix-store finishes.  With
  --keep-going and lots of top-level goals, it's possible to run out
  of file descriptors (this happened sometimes in the build farm for
  Nixpkgs).  Also, for failed derivation, it won't be possible to
  build it again  until the lock is released.
  
* Idem for locks on build users: these weren't released in a timely
  manner for failed top-level derivation goals.  So if there were more
  than (say) 10 such failed builds, you would get an error about
  having run out of build users.

b682fae9d9 * Build hooks: use nix-store --import. This prevents a redundant
scan for runtime dependencies (i.e. the local machine shouldn't do a
  scan that the remote machine has already done).  Also pipe directly
  into `nix-store --import': don't use a temporary file.

019176137f * When using a build hook, distinguish between transient failures
(e.g. an SSH connection problem) and permanent failures (i.e. the
  builder failed).  This matters to Hydra (it wants to know whether it
  makes sense to retry a build).

c504d90c11 * Support i686-linux builds directly on x86_64-linux Nix
installations.  This is implemented using the personality() syscall,
  which causes uname to return "i686" in child processes.

92cb7c4dfe * Put chroots in the Nix store. This ensures that we can create hard

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.

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).

6776a52bb3 * Use a PathSet for the chroot directories so that we don't
accidentally bind-mount a directory twice.

d86bd22d24 * Define _GNU_SOURCE. Hopefully this fixes the build on Debian 4.0
(http://hydra.nixos.org/nixlog/384/1).

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.)

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.

5a569509b4 * Provide a minimal /etc/passwd in the chroot to keep some builders
happy.

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.

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.

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...

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.

5dfba0b4db * Force allocation of a pseudo-terminal to clean up the remote
nix-store process when the connection is interrupted.

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).

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.

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.

82ae85de27 * addToStore() in nix-worker: don't write the NAR dump received from
the client to a temporary directory, as that is highly inefficient.
