aab530e971 * Primop builtins.storePath for declaring a store path as a
dependency.  `storePath /nix/store/bla' gives exactly the same
  result as `toPath /nix/store/bla', except that the former includes
  /nix/store/bla in the dependency context of the string.

  Useful in some generated Nix expressions like nix-push, which now
  finally does the right thing wrt distributed builds.  (Previously
  the path to be packed wasn't an explicit dependency, so it wouldn't
  be copied to the remote machine.)

3f4ed681c2 * Prevent zombies. Previous the SIGCHLD handler only reaped one
zombie at a time, so if multiple children died before the handler
  got to run, some of them would not be cleaned up.

6fedb7aa0f * Restore SIGPIPE to SIG_DFL when running the builder. This prevents
subtle and often hard-to-reproduce bugs where programs in pipes
  either barf with a "Broken pipe" message or not, depending on the
  exact timing conditions.  This particularly happened in GNU M4 (and
  Bison, which uses M4).

709b55ee02 * Put the chroots under /nix/var/nix/chroots to reduce the risk of
disasters involving `rm -rf' on bind mounts.  Will try the
  definitive fix (per-process mounts, apparently possible via the
  CLONE_NEWNS flag in clone()) some other time.

c98ea254dc libstore: Always mount `/dev/pts' individually.
This fixes problems such as Tcl's PTY handling:

  ERROR: The system has no more ptys.  Ask your system administrator to
  create more.

f32fef1b07 * GC option `--max-atime' that specifies an upper limit to the last
accessed time of paths that may be deleted.  Anything more recently
  used won't be deleted.  The time is specified in time_t,
  e.g. seconds since 1970-01-01 00:00:00 UTC; use `date +%s' to
  convert to time_t from the command line. 

  Example: to delete everything that hasn't been used in the last two
  months:

  $ nix-store --gc -v --max-atime $(date +%s -d "2 months ago")

77afd97a99 * nix-store --gc / --delete: show how many store paths were deleted. 2008-09-17 12:53:33 +00:00
Eelco Dolstra
7ab68961e4 * Garbage collector: added an option `--use-atime' to delete paths in
order of ascending last access time.  This is useful in conjunction
  with --max-freed or --max-links to prefer deleting non-recently used
  garbage, which is good (especially in the build farm) since garbage
  may become live again.

  The code could easily be modified to accept other criteria for
  ordering garbage by changing the comparison operator used by the
  priority queue in collectGarbage().

7933cdc6dc * When writing the user environment manifest, filter out non-string
attributes from the meta attribute.  Not doing so caused nix-env to
  barf on the "psi" package, which has a meta.function attribute,
  the textual serialisation of which causes a gigantic string to be
  produced --- so big that it causes nix-env to run out of memory.

  Note however that "meta" really only should contain strings.  
  meta.function should be passthru.function.

2a01d06da6 Added nix-http-export.cgi to extra distributed scripts; so it can be installed from releases, not only from SVN. 2008-08-29 08:34:38 +00:00

7718b19389 * Explicitly set PWD to prevent problems with chroot builds. In
particular, dietlibc cannot figure out the cwd because the inode of
  the current directory doesn't appear in .. (because getdents returns
  the inode of the mount point).

9cc0da8453 * Create a /tmp with 1777 permission in the chroot. Some builders
need a writable /tmp (they don't respect $TMPDIR).

99dc3e613a * Require that __overrides is defined as a non-recursive attribute
(which means it can only be defined via "inherit"), otherwise we get
  scoping bugs, since __overrides can't be recursive (or at least, it
  would be hard).

d06be428f6 * Disable chroot builds for fixed-output derivations so that we don't
need /etc in the chroot (in particular, /etc/resolv.conf for
  fetchurl).  Not having /etc/resolv.conf in the chroot is a good
  thing, since we don't want normal derivations to download files.

b428adc267 * Strip off the `.nix' suffix from the attribute name for files in
~/.nix-defexpr,  otherwise the attribute cannot be selected with the
  `-A' option.  Useful if you want to stick a Nix expression directly
  in ~/.nix-defexpr.

b7ff182b6e Fixing an obvious typo in override code. I do not know whether it works correctly after the change, but at least it ca nbe compiled now. 2008-08-14 22:01:43 +00:00
Eelco Dolstra
ca07f3e370 * Another experimental feature: a way to truly override attributes in
a rec.  This will be very useful to allow end-user customisation of
  all-packages.nix, for instance globally overriding GCC or some other
  dependency.  The // operator doesn't cut it: you could replace the
  "gcc" attribute, but all other attributes would continue to
  reference the original value due to the substitution semantics of
  rec.

  The syntax is a bit hacky but this is to allow backwards
  compatibility.

9279174dde * Added an experimental feature suggested by Andres: ellipses ("...")
in attribute set pattern matches.  This allows defining a function
  that takes *at least* the listed attributes, while ignoring
  additional attributes.  For instance,

    {stdenv, fetchurl, fuse, ...}:
    
    stdenv.mkDerivation {
      ...
    };
    
  defines a function that requires an attribute set that contains the 
  specified attributes but ignores others.  The main advantage is that
  we can then write in all-packages.nix

    aefs = import ../bla/aefs pkgs;

  instead of

    aefs = import ../bla/aefs {
      inherit stdenv fetchurl fuse;
    };

  This saves a lot of typing (not to mention not having to update
  all-packages.nix with purely mechanical changes).  It saves as much
  typing as the "args: with args;" style, but has the advantage that
  the function arguments are properly declared (not implicit in what
  the body of the "with" uses).

1b962fc720 * @-patterns as in Haskell. For instance, in a function definition
f = args @ {x, y, z}: ...;

  `args' refers to the argument as a whole, which is further
  pattern-matched against the attribute set pattern {x, y, z}.

e818838412 * "pattern" non-terminal. 2008-08-14 10:14:34 +00:00
Eelco Dolstra
efe4b690ae * Refactoring: combine functions that take an attribute set and
functions that take a single argument (plain lambdas) into one AST
  node (Function) that contains a Pattern node describing the
  arguments.  Current patterns are single lazy arguments (VarPat) and
  matching against an attribute set (AttrsPat).

  This refactoring allows other kinds of patterns to be added easily,
  such as Haskell-style @-patterns, or list pattern matching.
