to have been fixed now.

Eelco Dolstra
4c356acd04 * In `nix-store --export', abort if the contents of a path has
changed.  This prevents corrupt paths from spreading to other
  machines.  Note that checking the hash is cheap because we're
  hashing anyway (because of the --sign feature).

594eaddd11 * When using the included sqlite/aterm libraries, build with
--enable-shared.
* In libutil/libstore/libexpr etc., link against sqlite and aterm.
* Some more header file hygiene.

84a4dd5ff0 * Don't use fdatasync since it doesn't work on Snow Leopard.
* Don't refer to config.h in util.hh, because config.h is not
  installed (http://hydra.nixos.org/build/303053).

20186a4079 Don't rely on `PATH_MAX' on GNU. 2010-02-10 15:55:50 +00:00
Eelco Dolstra
4bbbe25802 * Remove most Cygwin-specific code. Cygwin 1.7 implements advisory
POSIX locks, and simulates Unix-style file deletion semantics
  sufficiently.  Note that this means that Nix won't work on Cygwin
  1.5 anymore.

Eelco Dolstra
07ffdc2862 * Added an option "fsync-metadata" to fsync() changes to
/nix/var/nix/db.
* Removed the function writeStringToFile since it does (almost) the
  same thing as writeFile.

ef92a14bfe * Include config.h before the C library headers, because it defines
_FILE_OFFSET_BITS=64.  Without it, functions like stat() fail on
  large file sizes.  This happened with a Nix store on squashfs:

  $ nix-store --dump /tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds > /dev/null
  error: getting attributes of path `/tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds': Value too large for defined data type

  $ stat /tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds
  File: `/tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds'
  Size: 0               Blocks: 36028797018963968 IO Block: 1024   regular empty file

  (This is a bug in squashfs or mksquashfs, but it shouldn't cause Nix
  to fail.)

tag used in naming 'struct _ATerm'".

the "bytes/blocks freed" statistics.

Eelco Dolstra
f2c3fc5191 * Don't show trace information by default (`--show-trace' to enable).
NixOS evaluation errors in particular look intimidating and
  generally aren't very useful.  Ideally the builtins.throw messages
  should be self-contained.

098cb9d233 Add an ftruncate call paired with fallocate to play safe with some FSes (namely, BtrFS fallocate sets file size to allocated size, i.e. multiple of block size) 2009-05-04 08:10:24 +00:00
Eelco Dolstra
4e646b0ddb * Fix a few "comparison is always false/true due to limited range of
data type" warnings on 64-bit platforms.  The one in parser.y is
  likely to be a real bug.

3a2bbe7f8a * Simplify communication with the hook a bit (don't use file
descriptors 3/4, just use stdin/stderr).

77d272623f * NAR archives: handle files larger than 2^32 bytes. Previously it
would just silently store only (fileSize % 2^32) bytes.
* Use posix_fallocate if available when unpacking archives.
* Provide a better error message when trying to unpack something that
  isn't a NAR archive.

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
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).

ff762fb499 * Pass HashType values instead of strings. 2008-12-03 16:10:17 +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().

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
3c92ea399d * Make nix-env --dry-run print the paths to be substituted correctly
again.  (After the previous substituter mechanism refactoring I
  didn't update the code that obtains the references of substitutable
  paths.)  This required some refactoring: the substituter programs
  are now kept running and receive/respond to info requests via
  stdin/stdout.

5af84139a8 * --max-freed: support values >= 4 GB. 2008-06-18 15:20:33 +00:00

a72709afd8 * Some refactoring: put the GC options / results in separate structs.
* The garbage collector now also prints the number of blocks freed.

b0e92f6d47 * Merged the no-bdb branch (-r10900:HEAD

bd955e15e1 * GCC 4.3.0 (Fedora 9) compatibility fixes. Reported by Gour and
Armijn Hemel.

329025253d * Use /tmp/nix-build-<drvpath>-<counter> instead of
/tmp/nix-<pid>-<counter> for temporary build directories.  This
  increases purity a bit: many packages store the temporary build path
  in their output, causing (generally unimportant) binary differences.

df303666bc * Use strsignal if available to give better error messages for
builders that fail due to a signal.

633518628f * nix-env -e: support uninstalling by path, so that one can say
$ nix-env -e $(which firefox)

  or

    $ nix-env -e /nix/store/nywzlygrkfcgz7dfmhm5xixlx1l0m60v-pan-0.132

* nix-env -i: if an argument contains a slash anywhere, treat it as a
  path and follow it through symlinks into the Nix store.  This allows
  things like

    $ nix-build -A firefox
    $ nix-env -i ./result

* nix-env -q/-i/-e: don't complain when the `*' selector doesn't match
  anything.  In particular, `nix-env -q \*' doesn't fail anymore on an
  empty profile.

dc6f373842 * Delete the chroot directory automatically.
* Removed some debug messages.
2007-10-27 16:06:38 +00:00
Eelco Dolstra
9397cd30c8 * Support for doing builds in a chroot under Linux. The builder is
executed in a chroot that contains just the Nix store, the temporary
  build directory, and a configurable set of additional directories
  (/dev and /proc by default).  This allows a bit more purity
  enforcement: hidden build-time dependencies on directories such as
  /usr or /nix/var/nix/profiles are no longer possible.  As an added
  benefit, accidental network downloads (cf. NIXPKGS-52) are prevented
  as well (because files such as /etc/resolv.conf are not available in
  the chroot).

  However the usefulness of chroots is diminished by the fact that
  many builders depend on /bin/sh, so you need /bin in the list of
  additional directories.  (And then on non-NixOS you need /lib as
  well...)
