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 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 3d74274b37 * Updated `nix-store --verify' to the new schema. 2005-02-08 13:23:55 +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.

Eelco Dolstra 06b4424286 * Add missing files to dist.
* Fix GC and substitute bugs related to self-references.  Add a
  regression test.

Eelco Dolstra 1328aa3307 * Start of concurrent garbage collection. Processes write temporary
roots to a per-process temporary file in /nix/var/nix/temproots
  while holding a write lock on that file.  The garbage collector
  acquires read locks on all those files, thus blocking further
  progress in other Nix processes, and reads the sets of temporary
  roots.

Eelco Dolstra c505702265 * Fix and simplify the garbage collector (it's still not concurrent,
though).  In particular it's now much easier to register a GC root.
  Just place a symlink to whatever store path it is that you want to
  keep in /nix/var/nix/gcroots.

Eelco Dolstra a24b78e9f1 * Maintain the references/referers relation also for derivations.
This simplifies garbage collection and `nix-store --query
  --requisites' since we no longer need to treat derivations
  specially.

* Better maintaining of the invariants, e.g., setReferences() can only
  be called on a valid/substitutable path.

Eelco Dolstra 2a2756b856 * Simplification: registerSubstitutes -> registerSubstitute. We no
longer need the former since there we no longer have the
  substitutes-rev table (which triggered a O(n^2) cost in updating
  them).
2005-01-25 20:27:40 +00:00
Eelco Dolstra 066da4ab85 * Really fix the substitute mechanism, i.e., ensure the closure
invariant by registering references through the manifest.
* Added a test for nix-pull.
2005-01-25 17:08:52 +00:00
Eelco Dolstra c6290e42bc * Fix the `--fallback' switch.
* Fix the substitutes tests.
2005-01-25 13:00:12 +00:00
Eelco Dolstra 581fc47783 * Fix the build hook mechanism; pass the pointer graph to the hook. 2005-01-25 11:55:43 +00:00
Eelco Dolstra 80faa2f98a * In nix-store: change --build' back to --realise'. Also brought
back the query flag `--force-realise'.
* Fixed some of the tests.
2005-01-25 10:55:33 +00:00
Eelco Dolstra 6a0a2d5593 * Terminology fixes. 2005-01-20 16:01:07 +00:00
Eelco Dolstra 05f0430de1 * Another change to low-level derivations. The last one this year, I
promise :-) This allows derivations to specify on *what* output
  paths of input derivations they are dependent.  This helps to
  prevent unnecessary downloads.  For instance, a build might be
  dependent on the `devel' and `lib' outputs of some library
  component, but not the `docs' output.

Eelco Dolstra 96de272b48 * Renamed normalise.cc' -> build.cc', `storeexprs.cc' ->
`derivations.cc', etc.
* Store the SHA-256 content hash of store paths in the database after
  they have been built/added.  This is so that we can check whether
  the store has been messed with (a la `rpm --verify').
* When registering path validity, verify that the closure property
  holds.
