Eelco Dolstra 46e0919ced * `nix-store --export --sign': sign the Nix archive using the RSA key
in /nix/etc/nix/signing-key.sec
2007-02-21 14:31:42 +00:00
Eelco Dolstra b824a1daee * Start of `nix-store --export' operation for serialising a store
path.  This is like `nix-store --dump', only it also dumps the
  meta-information of the store path (references, deriver).  Will add
  a `--sign' flag later to add a cryptographic signature, which we
  will use for exchanging store paths between build farm machines in a
  secure manner.
2007-02-20 23:17:20 +00:00
Eelco Dolstra afe23b5f38 * nix-pack-closure: store the top-level store paths in the closure.
* nix-unpack-closure: extract the top-level paths from the closure and
  print them on stdout.  This allows them to be installed, e.g.,
  "nix-env -i $(nix-unpack-closure)".  (NIX-64)
2007-01-13 19:50:42 +00:00
Eelco Dolstra e24d0201c2 * Doh! 2006-12-07 22:07:05 +00:00
Eelco Dolstra 4ca01065c3 * Rename all those main.cc files. 2006-12-07 20:47:30 +00:00
Eelco Dolstra a9c4f66cfb * Allow unprivileged users to run the garbage collector and to do
`nix-store --delete'.  But unprivileged users are not allowed to
  ignore liveness.
* `nix-store --delete --ignore-liveness': ignore the runtime roots as
  well.
2006-12-05 02:18:46 +00:00
Eelco Dolstra 9c9cdb06d0 * Remove SwitchToOriginalUser, we're not going to need it anymore. 2006-12-02 14:34:14 +00:00
Eelco Dolstra a824d58b56 * Merge addToStore and addToStoreFixed.
* addToStore now adds unconditionally, it doesn't use readOnlyMode.
  Read-only operation is up to the caller (who can call
  computeStorePathForPath).
2006-12-01 20:51:18 +00:00
Eelco Dolstra 40b3f64b55 * Skeleton of the privileged worker program.
* Some refactoring: put the NAR archive integer/string serialisation
  code in a separate file so it can be reused by the worker protocol
  implementation.
2006-11-30 19:19:59 +00:00
Eelco Dolstra 6ecb840fd1 * Put building in the store API. 2006-11-30 18:02:04 +00:00
Eelco Dolstra e2ef5e07fd * Refactoring. There is now an abstract interface class StoreAPI
containing functions that operate on the Nix store.  One
  implementation is LocalStore, which operates on the Nix store
  directly.  The next step, to enable secure multi-user Nix, is to
  create a different implementation RemoteStore that talks to a
  privileged daemon process that uses LocalStore to perform the actual
  operations.
2006-11-30 17:43:04 +00:00
Eelco Dolstra 0541ddc7e3 * Turn off synchronisation between C and C++ I/O functions. This
gives a huge speedup in operations that read or write from standard
  input/output.  (So libstdc++'s I/O isn't that bad, you just have to
  call std::ios::sync_with_stdio(false).)  For instance, `nix-store
  --register-substitutes' went from 1.4 seconds to 0.1 seconds on a
  certain input.  Another victory for Valgrind.
2006-11-18 18:56:30 +00:00
Eelco Dolstra e40d4a5604 * Option --reregister' in nix-store --register-validity'. We need
this in the NixOS installer (or in the buildfarm) to ensure that the
  cryptographic hash of the path contents still matches the actual
  contents.
2006-11-13 16:48:27 +00:00
Eelco Dolstra ae6fb27f18 * `nix-store --read-log / -l PATH' shows the build log of PATH, if
available.  For instance,

    $ nix-store -l $(which svn) | less

  lets you read the build log of the Subversion instance in your
  profile.

* `nix-store -qb': if applied to a non-derivation, take the deriver.
2006-10-28 16:33:54 +00:00
Eelco Dolstra 9e08f5efe1 * Documented nix-store --dump / --restore. 2006-10-05 22:57:07 +00:00
Eelco Dolstra 25df501704 * GC options in nix-store --help (NIX-15). 2006-09-21 19:06:34 +00:00
Eelco Dolstra fc195519b5 * Sone missing #includes. 2006-09-05 08:54:48 +00:00
Eelco Dolstra 75068e7d75 * Use a proper namespace.
* Optimise header file usage a bit.
* Compile the parser as C++.
2006-09-04 21:06:23 +00:00
Eelco Dolstra 4250b641d8 * `nix-store --gc --print-dead': print the total size of the store
objects that would be freed.
2006-08-11 20:26:49 +00:00
Eelco Dolstra b5988004d6 * Support for srcdir != builddir (NIX-41). 2006-05-12 11:47:45 +00:00
Eelco Dolstra c8bfb11b34 * `nix-env (-i|-u) --dry-run' now shows exactly which missing paths
will be built or substituted.
2006-03-06 11:21:15 +00:00
Eelco Dolstra 7ba1fd2029 * Regularise help text a bit. 2006-03-06 11:04:39 +00:00
Eelco Dolstra 74166f2f44 * db.hh shouldn't depend on the Berkeley DB headers. 2006-03-01 17:44:28 +00:00
Eelco Dolstra b6780b9e10 * Uninitialised variable. Fixes the --delete test. 2006-03-01 14:39:42 +00:00
Eelco Dolstra 651ab439cf * A simple hack to fix NIX-18: the garbage collector cannot run when
the disk is full (because to delete something from the Nix store, we
  need a Berkeley DB transaction, which takes up disk space).  Under
  normal operation, we make sure that there exists a file
  /nix/var/nix/db/reserved of 1 MB.  When running the garbage
  collector, we delete that file before we open the Berkeley DB
  environment.
2006-02-16 13:19:15 +00:00
Eelco Dolstra 1029716a8a * Don't show cycles, they're not very useful. 2006-01-19 15:35:34 +00:00
Eelco Dolstra f96d2dea26 * Added a flag --ignore-liveness' to nix-store --delete'. It
deletes a path even if it is reachable from a root.  However, it
  won't delete a path that still has referrers (since that would
  violate store invariants).

  Don't try this at home.  It's a useful hack for recovering from
  certain situations in a somewhat clean way (e.g., holes in closures
  due to disk corruption).
2005-12-23 21:36:44 +00:00
Eelco Dolstra 4b9e7f59ca * Revived the old "nix-store --delete" operation that deletes the
specified paths from the Nix store.  However, this operation is
  safe: it refuses to delete anything that the garbage collector
  wouldn't delete.
2005-12-23 21:08:42 +00:00
Eelco Dolstra 530b27df1e * `nix-store --gc' prints out the number of bytes freed on stdout
(even when it is interrupted by a signal).
2005-12-15 21:11:39 +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 4c20a08293 * Build dynamic libraries. 2005-07-22 14:52:45 +00:00
Eelco Dolstra 52a2f41320 * Include some required header files. 2005-05-04 16:33:20 +00:00
Eelco Dolstra c702dfca3f * nix-store: --substitute' -> --register-substitutes'. 2005-04-08 13:48:41 +00:00
Eelco Dolstra 4271385a73 * Make `nix-store --query --tree' work on non-derivations (i.e., on
any store path).
2005-04-08 12:57:16 +00:00
Eelco Dolstra f9848d4f31 * Support base-32 hash representations. 2005-04-07 14:33:32 +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 6f788880b6 * Re-enable dot graph generation. 2005-03-26 22:06:57 +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 a04c62e0c4 * Canonicalise path meta-data in `nix-store --register-validity'. 2005-03-23 12:06:57 +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 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 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 e0181f56be * `nix-store -q --tree' shows a tree representing the dependency graph
of the given derivation.  Useful for getting a quick overview of how
  something was built.  E.g., to find out how the `baffle' program in
  your user environment was built, you can do

    $ nix-store -q --tree $(nix-store -qd $(which baffle))

  Tree nesting depth is minimised (?) by topologically sorting paths
  under the relation A < B iff A \in closure(B).
2005-02-17 15:57:46 +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 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 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 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.
