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'.

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.
2005-02-09 09:50:29 +00:00
Eelco Dolstra c547439843 * Subflag in --verify': nix-store --verify --check-contents' checks
that the contents of store paths has not changed by comparing hashes
  of their current contents to the hashes stored in the database.
2005-02-08 13:48:53 +00:00
Eelco Dolstra 3d74274b37 * Updated `nix-store --verify' to the new schema. 2005-02-08 13:23:55 +00:00
Eelco Dolstra fbc434ee4c * `nix-store -qb' to query derivation environment bindings. Useful
for finding build-time dependencies (possibly after a build).  E.g.,

    $ nix-store -qb aterm $(nix-store -qd $(which strc))
    /nix/store/jw7c7s65n1gwhxpn35j9rgcci6ilzxym-aterm-2.3.1

* Arguments to nix-store can be files within store objects, e.g.,
  /nix/store/jw7c...-aterm-2.3.1/bin/baffle.

* Idem for garbage collector roots.
2005-02-07 14:32:44 +00:00
Eelco Dolstra 450c358e20 * Maintain a database table (`derivers') that maps output paths to the
derivation that produced them.
* `nix-store -qd PATH' prints out the derivation that produced a path.
2005-02-07 13:40:40 +00:00
Eelco Dolstra a37338815d * A GC setting `gc-keep-outputs' to specify whether output paths of
derivations should be kept.
2005-02-01 22:07:48 +00:00
Eelco Dolstra 65b6c8ab4c * Move root finding from nix-collect-garbage' to nix-store --gc'.
This was necessary becase root finding must be done after
  acquisition of the global GC lock.

  This makes `nix-collect-garbage' obsolete; it is now just a wrapper
  around `nix-store --gc'.

* Automatically remove stale GC roots (i.e., indirect GC roots that
  point to non-existent paths).
2005-02-01 15:05:32 +00:00
Eelco Dolstra 630ae0c9d7 * nix-build: use an indirection scheme to make it easier for users to
get rid of GC roots.  Nix-build places a symlink `result' in the
  current directory.  Previously, removing that symlink would not
  remove the store path being linked to as a GC root.  Now, the GC
  root created by nix-build is actually a symlink in
  `/nix/var/nix/gcroots/auto' to `result'.  So if that symlink is
  removed the GC root automatically becomes invalid (since it can no
  longer be resolved).  The root itself is not automatically removed -
  the garbage collector should delete dangling roots.
2005-02-01 13:48:46 +00:00
Eelco Dolstra dcc37c236c * nix-store, nix-instantiate: added an option `--add-root' to
immediately add the result as a permanent GC root.  This is the only
  way to prevent a race with the garbage collector.  For instance, the
  old style

    ln -s $(nix-store -r $(nix-instantiate foo.nix)) \
      /nix/var/nix/gcroots/result

  has two time windows in which the garbage collector can interfere
  (by GC'ing the derivation and the output, respectively).  On the
  other hand,

    nix-store --add-root /nix/var/nix/gcroots/result -r \
      $(nix-instantiate --add-root /nix/var/nix/gcroots/drv \
        foo.nix)

  is safe.

* nix-build: use `--add-root' to prevent GC races.
2005-02-01 12:36:25 +00:00
Eelco Dolstra 06b4424286 * Add missing files to dist.
* Fix GC and substitute bugs related to self-references.  Add a
  regression test.
2005-02-01 09:23:38 +00:00
Eelco Dolstra 32fa82a56a * Acquire a global GC lock to prevent new temporary root files from
being created after the garbage collector has read the temproots
  directory.  This blocks the creation of new processes, but the
  garbage collector could periodically release the GC lock to allow
  them to run.
2005-01-31 22:23:49 +00:00
Eelco Dolstra 89c9bc11ab * Add a test for a more subtle race: a process starting after the
temporary root files have been read but creating outputs before the
  store directory has been read.
