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.

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.

Eelco Dolstra a55113411f * Nix daemon: reload the configuration file after forking (NIX-100). 2008-11-20 12:25:11 +00:00

Eelco Dolstra 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.)

Eelco Dolstra 63ccd72496 * Updated the manual. 2008-11-19 17:00:32 +00:00
Eelco Dolstra e13da525a7 * Files in the info directory starting with "." are temporary files
and don't indicate path validity.

Eelco Dolstra 5d250ad1ea * nix-store --dump-db: be more streamy. 2008-11-19 16:26:34 +00:00
Eelco Dolstra 7509d70f9d * Documented some of the sharing mechanisms. 2008-11-19 15:20:46 +00:00
Eelco Dolstra 2369b122d1 * Install documentation in $(docdir) (i.e. share/doc/nix). 2008-11-19 13:19:09 +00:00
Eelco Dolstra 6c2c771af7 * Removed obsolete option. 2008-11-19 13:18:46 +00:00
Eelco Dolstra 07d3a38726 * Remove references to Berkeley DB, including most of the
troubleshooting section.  W00t.

Eelco Dolstra f5325d292d * Release notes. 2008-11-19 10:59:36 +00:00
Eelco Dolstra fa791116a3 * Get rid of nix-pack-closure / nix-unpack-closure, they're redundant. 2008-11-18 14:43:40 +00:00
Eelco Dolstra 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.
2008-11-14 16:50:01 +00:00
Eelco Dolstra 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).
2008-11-14 15:46:45 +00:00
Eelco Dolstra a519bb0635 * Some somewhat ad hoc mechanism to allow the build farm to monitor
build progress.
2008-11-12 11:08:27 +00:00
Eelco Dolstra 96598e7b06 * Pass the --no-build-output flag to the daemon. 2008-11-11 15:11:10 +00:00
Eelco Dolstra 4166b11a53 * Add /dev/pts to the default nix.conf. 2008-11-11 14:59:20 +00:00
Eelco Dolstra 2b7c839b4e * Typo. 2008-11-11 14:58:37 +00:00
Eelco Dolstra 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.

Ludovic Courtès 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.

Eelco Dolstra 9d6d50269b * Bug fix for building on some old installations (contributed by Pjotr). 2008-10-16 14:16:03 +00:00
Eelco Dolstra fa61ee70ee * Fix `--from-profile'. 2008-09-18 09:08:54 +00:00
Eelco Dolstra 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")

Eelco Dolstra 4af2fdba6d * Typo. 2008-09-17 13:00:55 +00:00
Eelco Dolstra c987061aa4 * Some refactoring. Better output with `-v' for --use-atime. 2008-09-17 12:54:07 +00:00
Eelco Dolstra 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().

Eelco Dolstra 2b2aa8a820 * Doh. 2008-09-08 11:02:15 +00:00
Eelco Dolstra 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.

Eelco Dolstra 0f0dbe8c0c * Extend the ATerm suppressions to 64-bit. 2008-08-29 14:38:04 +00:00
Eelco Dolstra 311c222f47 2008-08-29 13:59:03 +00:00
Michael Raskin 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
Eelco Dolstra 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).
2008-08-27 17:20:25 +00:00
Eelco Dolstra 9cc0da8453 * Create a /tmp with 1777 permission in the chroot. Some builders
need a writable /tmp (they don't respect $TMPDIR).
2008-08-27 16:03:03 +00:00
Eelco Dolstra 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).
2008-08-26 14:05:59 +00:00
Eelco Dolstra 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.
2008-08-25 15:49:22 +00:00
Eelco Dolstra abec1c0004 * Evaluate attributes in sorted order for better determinism. 2008-08-25 14:31:29 +00:00
Eelco Dolstra c4f1c2114b * Minor simplification. 2008-08-25 14:15:56 +00:00
Eelco Dolstra 49829da8b4 * Doh. 2008-08-25 13:32:27 +00:00
Eelco Dolstra 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.
2008-08-25 13:31:57 +00:00
Eelco Dolstra cc826dc03e * Simplify the Valgrind suppressions using wildcards. 2008-08-22 14:32:29 +00:00
Eelco Dolstra 51e2dda58c * Some more ATerm Valgrind suppressions. 2008-08-19 12:46:43 +00:00
Michael Raskin 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.
2008-08-14 16:59:37 +00:00
Eelco Dolstra 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).

Eelco Dolstra db4f4a8425 * Backward compatibility check to prevent nixos-rebuild from barfing
when upgrading Nix.
