Eelco Dolstra a33b561a6b * Use Berkeley DB 4.4's process registry feature to recover from 
crashed Nix instances, and toss out our own recovery code.
 2005-12-09 22:55:07 +00:00
Eelco Dolstra 760264bffe * Require Berkeley DB 4.4. 
* Checkpoint after an upgrade.
 2005-12-06 15:00:04 +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
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 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.
 2005-10-17 15:33:24 +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 8d06842a76 * Configuration options for trusted local builds. 2005-09-21 12:19:39 +00:00
Eelco Dolstra ef9e2c8e73 * Typo. 2005-09-20 16:14:00 +00:00
Eelco Dolstra 4c20a08293 * Build dynamic libraries. 2005-07-22 14:52:45 +00:00
Eelco Dolstra 109cde6706 * Ignore (with a warning) invalid garbage collector roots. 2005-05-10 14:56:10 +00:00
Eelco Dolstra 456f3251d2 * Typo. 2005-05-10 14:21:46 +00:00
Eelco Dolstra 8f57634c14 * Automatically upgrade the Berkeley DB environment if necessary. 2005-05-09 15:25:47 +00:00
Eelco Dolstra 6057b51835 * Don't try to register GC roots in read-only mode. 2005-05-07 21:33:31 +00:00
Eelco Dolstra 5dea0622d1 * Idem (constness fix). 
* `compare' in GCC 2.95 is broken.
 2005-05-04 16:31:49 +00:00
Eelco Dolstra 4a266e35d4 * GCC 2.95 compatibility fix in constness; strangely, I think this 
should not have worked at all.
 2005-05-04 16:31:24 +00:00
Eelco Dolstra f913283570 * Remove redundant message. 2005-04-13 09:20:27 +00:00
Eelco Dolstra f3660b1c8c * Garbage collector fix: allow deletion of paths that have invalid 
(but substitutable) referers.
 2005-04-12 10:51:00 +00:00
Eelco Dolstra cab7816b56 * Slightly nicer message. 2005-04-11 08:07:41 +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 298dd487bb * When finding live paths, the deriver need not be valid. 2005-03-25 14:31:12 +00:00
Eelco Dolstra 7eaf038763 * `nix-store --verify': repair bad referer mappings. 2005-03-25 14:21:49 +00:00
Eelco Dolstra c6178f0b03 * Create missing log and temproots directories automatically (reported 
by Rob).
 2005-03-24 17:46:38 +00:00
Eelco Dolstra 0df9f08078 * Export the references graph to the build hook. 2005-03-23 13:16:36 +00:00
Eelco Dolstra 3f236f01ae * `nix-store --register-validity': allow a path to refer to a path 
listed later in the list of new valid paths.
 2005-03-23 13:07:28 +00:00
Eelco Dolstra f20f081560 * nix-store: --isvalid' -> --check-validity', `--validpath' -> 
`--register-validity'.
* `nix-store --register-validity': read arguments from stdin, and
  allow the references and deriver to be set.
 2005-03-23 11:25:20 +00:00
Eelco Dolstra c757d16c8c * Bug in clearSubstitutes(). 2005-03-14 18:54:40 +00:00
Eelco Dolstra 4bbdcfbb45 * Don't use fork() in copyPath(), but a string buffer. 2005-03-03 13:58:02 +00:00
Eelco Dolstra 86cb3cc554 * Increase Berkeley DB limits a bit more. 
* Maintain the cleanup invariant in clearSubstitutes().
 2005-03-03 13:10:44 +00:00
Eelco Dolstra 07b4399fb6 * `nix-store -q --hash' to quickly query the hash of the contents of a 
store path (which is stored in the database).
 2005-03-02 15:57:06 +00:00
Eelco Dolstra bfaf83a0fd * When multiple derivations are specified in `nix-store -r', don't 
continue building when one fails unless `--keep-going' is
  specified.
* When `--keep-going' is specified, print out the set of failing
  derivations at the end (otherwise it can be hard to find out which
  failed).
 2005-02-23 11:19:27 +00:00
Eelco Dolstra 3a2c3f0cf2 * Support for fixed-output hashes over directory trees (i.e., over the 
NAR dump of the path).
 2005-02-22 21:14:41 +00:00
Eelco Dolstra eda2c3c253 * Compatibility hack so that Nixpkgs can continue to do hash checking 
in `fetchurl' in Nix <= 0.7, but doesn't in Nix 0.8.
 2005-02-22 15:23:24 +00:00
Eelco Dolstra 3c1630131e * Subtle bug in the builder: if a subgoal that is instantiated 
multiple times is also a top-level goal, then the second and later
  instantiations would never be created because there would be a
  stable pointer to the first one that would keep it alive in the
  WeakGoalMap.
* Some tracing code for debugging this kind of problem.
 2005-02-18 09:50:20 +00:00
Eelco Dolstra 8a3a96dd5b * Switch to the calling user context for some more operations in a 
setuid installation.
 2005-02-17 13:55:18 +00:00
Eelco Dolstra 88273f9574 * Put build logs in $prefix/var/nix/log/drvs/. 2005-02-17 13:54:45 +00:00
Eelco Dolstra 8992fce3da * It is now possible to add store derivations or paths directly to a 
user environment, e.g.,

    $ nix-env -i /nix/store/z58v41v21xd3ywrqk1vmvdwlagjx7f10-aterm-2.3.1.drv

  or 

    $ nix-env -i /nix/store/hsyj5pbn0d9iz7q0aj0fga7cpaadvp1l-aterm-2.3.1

  This is useful because it allows Nix expressions to be bypassed
  entirely.  For instance, if only a nix-pull manifest is provided,
  plus the top-level path of some component, it can be installed
  without having to supply the Nix expression (e.g., for obfuscation,
  or to be independent of Nix expression language changes or context
  dependencies).
 2005-02-14 17:35:10 +00:00
Eelco Dolstra a04a5de8f7 * Implement the `gc-keep-derivations' global configuretion flag. 2005-02-14 14:16:56 +00:00
Eelco Dolstra 6a8ef36fe6 * Global configuration option `env-keep-derivations' to store pointer 
to derivations in user environments.  Nice for developers (since it
  prevents build-time-only dependencies from being GC'ed, in
  conjunction with `gc-keep-outputs').  Turned off by default.
 2005-02-14 13:07:09 +00:00
Eelco Dolstra 32429142cd * Type error in constructor call (caught by GCC 3.3, but not 3.4!). 2005-02-14 09:53:11 +00:00
Eelco Dolstra 80870d9291 * Input sources should be in the set of all referenceable paths too. 2005-02-11 16:03:47 +00:00
Eelco Dolstra 3a99616968 * Commit more often to prevent out-of-memory errors. 2005-02-09 14:37:24 +00:00
Eelco Dolstra 98df735b51 * Propagate the deriver of a path through the substitute mechanism. 
* Removed some dead code (successor stuff) from nix-push.
* Updated terminology in the tests (store expr -> drv path).
* Check that the deriver is set properly in the tests.
 2005-02-09 12:57:13 +00:00
Eelco Dolstra 582e01c06f * Automatically upgrade <= 0.7 Nix stores to the new schema (so that 
existing user environments continue to work).
* `nix-store --verify': detect incomplete closures.
