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.

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).

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.

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 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 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.

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).

Eelco Dolstra a519bb0635 * Some somewhat ad hoc mechanism to allow the build farm to monitor
build progress.

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

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
