Eelco Dolstra ebcccbd358 * Added a tool to find additional roots for the garbage collector,
such as open files, current directories, mmaped files, etc.  This is
  inherently unportable, but it's easy to adapt this script to other
  platforms.  Currently we call `lsof' and try to read various bits in
  /proc/NNN.

  The goal is to prevent the garbage collector from removing store
  paths that are no longer reachable from a permanent root but that
  are still in use (for instance, after the user has done "nix-env -e"
  on a running program).

Eelco Dolstra 04cf72287b * This may be useful in the future. 2006-05-31 09:24:54 +00:00
Eelco Dolstra e3c07782d1 * Remove old manifests in `nix-channel --update'. 2006-05-08 20:00:28 +00:00
Eelco Dolstra 05bb644890 * Allow the resulting symlink of nix-build to be named, e.g.,
$ nix-build .../i686-linux.nix -A apacheHttpd -o apache

Eelco Dolstra 9811815429 * Write messages to stderr, not stdout. 2006-03-10 09:41:28 +00:00
Eelco Dolstra 120f00c04f * More online help. 2006-03-03 14:25:07 +00:00
Eelco Dolstra 2d54312f87 * Rewrote nix-build in Perl, since sh is just too limited (turns out
that arrays are a bash extension, so it didn't work on FreeBSD).
  Also fixes NIX-8 (readlink(1) dependency).
2006-03-03 14:15:02 +00:00
Eelco Dolstra 85793fa438 * Remove debug statement. 2006-02-24 17:10:38 +00:00
Eelco Dolstra e2f16b9cae * A script to remove from a manifest those patches whose base or
target no longer applies to any available release.  This is a
  partial fix for NIX-34 (when producing linear patch sequences
  between releases, the number of patches grows without bound).

Eelco Dolstra 5168f9bb00 * Canonicalise manifests a bit by sorting them. 2006-02-24 16:02:36 +00:00
Eelco Dolstra 43fa1c20e7 * Separate the cache reading code. 2006-02-22 14:35:19 +00:00
Eelco Dolstra 928cce5922 * Directory for nix.cs.uu.nl manifest / cache maintenance scripts. 2006-02-22 14:13:02 +00:00
Eelco Dolstra fcec32a2c5 * Use right directories for NAR files and patches.
* Print errors to STDERR.
2006-02-22 14:10:02 +00:00
Eelco Dolstra 982399bb14 * Enable the --attr in nix-build as well (and add -A as an alias).
Example:

    $ nix-build ./all-packages.nix -A xlibs.libX11

  So finally it's easy to perform a test build of a Nix expression!
2006-02-10 17:37:35 +00:00
Eelco Dolstra 151f10dbc7 * Add @bindir@. 2006-02-01 12:41:54 +00:00
Eelco Dolstra 83424eb71b * Don't force a build of derivations. 2006-01-26 23:18:46 +00:00
Eelco Dolstra e4d4969ae9 * New tools nix-pack-closure and nix-unpack-closure. These provide a
useful way to transfer the closure of a store path to another
  machine.

  These commands provide functionality previously possible through
  `nix-push --copy'.  However, they are much more convenient in many
  situations (though possibly less efficient).
  
  Example:
  $ nix-pack-closure /nix/store/hj232g1r...-subversion-1.3.0 > svn.closure
  (on another machine:)
  $ nix-unpack-closure < svn.closure

  Note that Subversion is added to the store, but not installed into a
  user environment.  One should do `nix-env -i
  /nix/store/hj232g1r...-subversion-1.3.0' for that.

  Another example: copy the application Azureus to the machine
  `scratchy' through ssh:
  
  $ nix-pack-closure $(which azureus) | ssh scratchy nix-unpack-closure
2006-01-12 15:17:51 +00:00
Eelco Dolstra ab5c6bb3a3 * Change referer' to referrer' throughout. In particular, the
nix-store query options `--referer' and `--referer-closure' have
  been changed to `--referrer' and `--referrer-closure' (but the old
  ones are still accepted for compatibility).
2005-12-13 21:04:48 +00:00
Eelco Dolstra dc528128cc * FreeBSD compatibility fix. 2005-11-17 13:58:23 +00:00
Eelco Dolstra 221c79013f * Turn off build hooks in nix-push because of an impurity (NIX-21). 2005-10-29 18:17:45 +00:00
Armijn Hemel 15ff877438 add @coreutils@ to correctly use coreutils to create a profile. This is needed
for NixOS, where we might not know our PATH in advance.
2005-10-11 17:30:57 +00:00
Eelco Dolstra 607a2f01e6 * Remove other uses of IPC::Open2. 2005-09-21 17:14:52 +00:00
Eelco Dolstra 95304172a5 * Don't use IPC::Open2, it has a subtle race bug on Mac OS X 10.4. If
the parent runs before the child, it closes some pipe file
  descriptors which causes the child to fail due to a bad file
  descriptor.  So we just use the normal open() function instead.
  
  This fixes NIX-14 (intermittent nix-pull failures).
2005-09-21 17:06:06 +00:00
Eelco Dolstra d34fa9a6cc * Remove dead file. 2005-09-16 09:05:18 +00:00
Eelco Dolstra 846b53bde4 * Set the current directory to something well-defined. Might help in
setuid installations.
2005-09-16 09:03:24 +00:00
Eelco Dolstra 7f384d9c1b * Use a proper temporary directory. 2005-09-15 15:21:35 +00:00
Eelco Dolstra a5ceb5bc0b * nix-build: default to `./default.nix' if no paths are specified.
So when using Nix as a build tool, you can just say `nix-build' and
  it will build the top-level derivation defined in `default.nix'.
2005-07-13 17:39:10 +00:00
Eelco Dolstra 928a7c06dc * Don't create patches for archives >= 150 MB because bsdiff can't
handle it.  It crashed on the 234 MB tetex archive.  Probably we
  will never be able to handle archives of that size on 32-bit
  machines (because bsdiff does everything in memory requiring
  max(17*n,9*n+m)+O(1) bytes, so the address space simply isn't
  there).
2005-06-18 14:20:24 +00:00
Eelco Dolstra cbc8d083ac * Make unpacking of patch sequences much faster by not doing redundant
unpacking and repacking of intermediate paths.
2005-05-10 14:22:36 +00:00
Eelco Dolstra 9f3601a36c * Argh! The patch downloader was broken due to the renaming of the
`--isvalid' flag in nix-store.
2005-04-12 10:51:38 +00:00
Eelco Dolstra d5219a351a * Damn. Disable the USE heuristic for now, since the deriver in the
database isn't always in the manifest (so the reference graph cannot
  be reconstructed fully).
2005-04-12 10:07:02 +00:00
Eelco Dolstra c702dfca3f * nix-store: --substitute' -> --register-substitutes'. 2005-04-08 13:48:41 +00:00
Eelco Dolstra 7d876f8fa7 * Get rid of fetchurl, we don't need it anymore. 2005-04-07 14:35:44 +00:00
Eelco Dolstra c815aff21b * `nix-store --add-fixed' to preload the outputs of fixed-output
derivations.  This is mostly to simplify the implementation of
  nix-prefetch-{url, svn}, which now work properly in setuid
  installations.

* Enforce valid store names in `nix-store --add / --add-fixed'.
2005-04-07 14:01:51 +00:00
Eelco Dolstra 31e140d70b * I said it couldn't be done. I was wrong. 2005-04-04 15:18:19 +00:00
Eelco Dolstra ebe342c9c1 * Better error checking. 2005-03-25 14:30:01 +00:00
Eelco Dolstra 7272c3f817 * Ignore hash conflicts in gc-releases.pl. 2005-03-18 09:43:25 +00:00
Eelco Dolstra e52ae1c0ff * Use SHA-256 for nix-push. 2005-03-15 11:12:48 +00:00
Eelco Dolstra 5675d5f488 * Idem. 2005-03-14 18:55:46 +00:00
Eelco Dolstra 6fb5f7e532 * Pass `--base32' unless using MD5. 2005-03-14 18:55:29 +00:00
Eelco Dolstra bb2e53699f * Parse new hash format properly. 2005-03-14 17:05:42 +00:00
Eelco Dolstra 5863f24722 * Print SHA-1 hashes in base-32 by default. 2005-03-14 17:05:20 +00:00
Eelco Dolstra bd333b939c * Prefix hash algorithm in patch generator too. 2005-03-14 16:46:19 +00:00
Eelco Dolstra 8eff18cd43 * Set NAR name to content hash; previous nix-push names were not
unique.
* Drop `hashAlgo' attribute in manifests; prefix hashes with the hash
  algorithm instead.
2005-03-14 15:09:53 +00:00
Eelco Dolstra 1562dfe9ba * Script to garbage collect nix-push directories. It prints out all
file names in the directory not included in any of the manifests
  specified on the command line.
2005-03-14 14:03:41 +00:00
Eelco Dolstra 536f324177 * nix-install-package: install outPath, not drvPath, for now.
* nix-prefecth-url: print out in base-16.
2005-03-11 15:27:37 +00:00
Eelco Dolstra 9e6bca8765 * Channel fix. 2005-03-03 13:10:52 +00:00
Eelco Dolstra 9e50e648a4 * Doh! 2005-03-01 11:27:38 +00:00
Eelco Dolstra 8d364e5baa * Add missing file to dist. 2005-03-01 11:27:22 +00:00
Eelco Dolstra db322a47ff * Use a weighted use heuristic to disambiguate between multiple
occurances of a component.  If the shortest path distance between a
  component P and Q in the referers graph is D, then the contribution
  of Q to the use of P is 1 / R^D, where R >= 1, typically 2.  This
  expresses that distant indirect uses are less important than nearby
  uses.

  For instance, this can disambiguate between the bootstrap GCC in
  Nixpkgs and the GCC of the final stdenv (the former has more uses,
  but they are further away),  and between the GCC of the final stdenv
  and the GCC+G77 build (the latter has very few uses).
