Eelco Dolstra dc528128cc * FreeBSD compatibility fix. 2005-11-17 13:58:23 +00:00
Eelco Dolstra 44409f52c1 * "Fix" the test, since we cannot feasibly support the intended semantics. 2005-11-17 11:58:22 +00:00
Eelco Dolstra b7f008fc35 * Did something useful while waiting at IAD: reference scanning is now 
much faster.
 2005-11-16 08:27:06 +00:00
Eelco Dolstra 9311ab76a5 * Install signal handlers for SIGTERM and SIGHUP. This ensures that 
Nix is properly shut down when it receives those signals.  In
  particular this ensures that killing the garbage collector doesn't
  cause a subsequent database recovery.
 2005-11-04 15:34:09 +00:00
Eelco Dolstra 5bf939885a * Memoise checkVarDefs since internally produced terms (i.e., not the 
result of parsing) can have very heavy sharing, causing exponential
  complexity if we naively recurse into them.  ATerms are graphs, not
  trees!
 2005-11-04 15:17:05 +00:00
Eelco Dolstra 1f285cf556 * Scoping bug in `with'. 2005-11-04 14:50:33 +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
Rob Vermaas f0856fd905 * Repair the referers table from the references table. 2005-10-29 15:44:02 +00:00
Eelco Dolstra 92d599c6a7 * Prevent uids from being used for more than one build 
simultaneously.  We do this using exclusive locks on uid files in
  /nix/var/nix/userpool, e.g., /nix/var/nix/userpool/123 for uid 123.
 2005-10-20 16:58:34 +00:00
Eelco Dolstra e932c40f8e * Oops. Fixed-output derivations were broken. 2005-10-19 14:27:44 +00:00
Eelco Dolstra 1b43fbd8e4 * Oops, that should be Berkeley DB 4.3. Reported by Gerco Ballintijn. 2005-10-18 14:09:43 +00:00
Eelco Dolstra 13b089c890 * Also kill all processes of the build user after the build. This is 
critical to prevent certain kinds of 0wnage.
 2005-10-17 17:43:21 +00:00
Eelco Dolstra f1b3a418fa * Before starting a build under some uid, kill all current processes 
running under that uid.
 2005-10-17 17:35:37 +00:00
Eelco Dolstra 439823ae80 * Check that the build result is owned by the build user, and that 
nobody else has write permission to the build result.  This catches
  most hack attempts.
 2005-10-17 16:59:25 +00:00
Eelco Dolstra 7ef574e5d0 * Don't use FIFOs to make Nix create the output path on behalf of the 
builder.  Instead, require that the Nix store has sticky permission
  (S_ISVTX); everyone can created files in the Nix store, but they
  cannot delete, rename or modify files created by others.
 2005-10-17 16:52:29 +00:00
Eelco Dolstra 32282abcea * Beginning of secure multi-user Nix stores. If Nix is started as 
root (or setuid root), then builds will be performed under one of
  the users listed in the `build-users' configuration variables.  This
  is to make it impossible to influence build results externally,
  allowing locally built derivations to be shared safely between
  users (see ASE-2005 paper).

  To do: only one builder should be active per build user.

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 0f133ae8d2 * Use ATerm 2.4.2. 2005-10-11 12:41:12 +00:00
Eelco Dolstra dfbf520ec2 * Swap the system and version comparion columns. 2005-10-06 15:51:59 +00:00
Eelco Dolstra 62412c5874 * Document `nix-env --compare-versions'. 2005-10-06 15:51:43 +00:00
Eelco Dolstra cec2be64f3 * Only colorise if we are attached to a terminal. 2005-10-06 15:01:46 +00:00
Eelco Dolstra b87b9c0d1f * New query option: --compare-versions' or -c' to compare installed 
versions to available versions, or vice versa.

  For example, the following compares installed versions to available
  versions:

    $ nix-env -qc
    autoconf-2.59            = 2.59
    automake-1.9.4           < 1.9.6
    f-spot-0.0.10            - ?
    firefox-1.0.4            < 1.0.7
    ...

  I.e., there are newer versions available (in the current default Nix
  expression) for Automake and Firefox, but not for Autoconf, and
  F-Spot is missing altogether.

  Conversely, the available versions can be compared to the installed
  versions:

    $ nix-env -qac
    autoconf-2.59                  = 2.59
    automake-1.9.6                 > 1.9.4
    bash-3.0                       - ?
    firefox-1.0.7                  > 1.0.4
    ...

  Note that bash is available but no version of it is installed.

  If multiple versions are available for comparison, then the highest
  is used.  E.g., if Subversion 1.2.0 is installed, and Subversion
  1.1.4 and 1.2.3 are available, then `nix-env -qc' will print `<
  1.2.3', not `> 1.1.4'.

  If higher versions are available, the version column is printed in
  red (using ANSI escape codes).

Eelco Dolstra 0e0041b2b6 * Update NEWS in the root directory properly. 2005-10-05 13:01:45 +00:00
Eelco Dolstra 0e38578433 * log2xml -> nix-log2xml. 2005-10-05 09:42:13 +00:00
Eelco Dolstra d47e03fccd * Install the XSL stylesheets for log to html conversion. 2005-10-05 09:37:58 +00:00
Eelco Dolstra ed4de220d2 * Use "source" instead of ".". 2005-09-28 09:00:07 +00:00
Eelco Dolstra ebfe57166d * Lets not go wild with templates. 2005-09-22 17:23:43 +00:00
Eelco Dolstra 4578a490ce * Parse multi-valued options. 2005-09-22 15:43:22 +00:00
Eelco Dolstra fbedf6056e * Merge release notes. 2005-09-22 12:23:22 +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).

Eelco Dolstra a864aca44c * This doesn't parse for now. 2005-09-21 17:02:48 +00:00
Eelco Dolstra 8d06842a76 * Configuration options for trusted local builds. 2005-09-21 12:19:39 +00:00
Eelco Dolstra 89cd0f57b1 * Use -all_load on Mac OS X. 2005-09-21 11:12:43 +00:00
Eelco Dolstra ef9e2c8e73 * Typo. 2005-09-20 16:14:00 +00:00
Eelco Dolstra 25d217684b * Use a statically linked ATerm library and build it at -O1, since 
higher optimisation levels cause statically linked libraries to
  barf.
 2005-09-18 20:27:02 +00:00
Eelco Dolstra f4fe3bd5b1 * Bump the version number to 0.10. 2005-09-16 13:47:03 +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 896c0b92f3 * This is not a GNU project :-P 2005-09-15 09:18:21 +00:00
Eelco Dolstra 5818e8eeaf * Remove dead code. 2005-09-14 18:51:02 +00:00
Eelco Dolstra 025086edea * Release notes in Docbook; ASCII release notes (i.e., the `NEWS' 
file) is now generated from that using `w3m' and some XSL hackery.
 2005-09-14 18:50:45 +00:00
Eelco Dolstra ed1db42915 * List concatenation must be right-associative for efficiency. 2005-09-14 11:41:59 +00:00
