Eelco Dolstra 49f59dceca * Move parseHash16or32 into libutil, and use in nix-hash. 2011-12-02 11:47:06 +00:00
Eelco Dolstra 5bbd693cae * Add an API function exportPaths() that provides the functionality of
‘nix-store --export’.
* Add a Perl module that provides the functionality of
  ‘nix-copy-closure --to’.  This is used by build-remote.pl so it no
  longer needs to start a separate nix-copy-closure process.  Also, it
  uses the Perl API to do the export, so it doesn't need to start a
  separate nix-store process either.  As a result, nix-copy-closure
  and build-remote.pl should no longer fail on very large closures due
  to an "Argument list too long" error.  (Note that having very many
  dependencies in a single derivation can still fail because the
  environment can become too large.  Can't be helped though.)
2011-11-23 15:13:37 +00:00
Eelco Dolstra e6cb3d0a0d * Added a command ‘nix-store --verify-paths PATHS’ to check whether
the contents of any of the given store paths have been modified.
  E.g.

    $ nix-store --verify-path $(nix-store -qR /var/run/current-system)
    path `/nix/store/m2smyiwbxidlprfxfz4rjlvz2c3mg58y-etc' was modified! expected hash `fc87e271c5fdf179b47939b08ad13440493805584b35e3014109d04d8436e7b8', got `20f1a47281b3c0cbe299ce47ad5ca7340b20ab34246426915fce0ee9116483aa'

  All paths are checked; the exit code is 1 if any path has been
  modified, 0 otherwise.
2011-09-06 12:06:30 +00:00
Eelco Dolstra 93227ff65c * Eliminate all uses of the global variable ‘store’ from libstore.
This should also fix:

    nix-instantiate: ./../boost/shared_ptr.hpp:254: T* boost::shared_ptr<T>::operator->() const [with T = nix::StoreAPI]: Assertion `px != 0' failed.

  which was caused by hashDerivationModulo() calling the ‘store’
  object (during store upgrades) before openStore() assigned it.
2011-08-31 21:11:50 +00:00
Eelco Dolstra e60c962fb8 * Add an operation `nix-store -q --size'. 2010-11-17 12:40:52 +00:00
Eelco Dolstra a3883cbd28 * Store the size of a store path in the database (to be precise, the
size of the NAR serialisation of the path, i.e., `nix-store --dump
  PATH').  This is useful for Hydra.
2010-11-16 17:11:46 +00:00
Eelco Dolstra fb9368b5a0 * Sync with the trunk. 2010-11-16 12:49:47 +00:00
Eelco Dolstra 705868a8a9 * Make sure that config.h is included before the system headers,
because it defines _FILE_OFFSET_BITS.  Without this, on 
  OpenSolaris the system headers define it to be 32, and then 
  the 32-bit stat() ends up being called with a 64-bit "struct 
  stat", or vice versa.

  This also ensures that we get 64-bit file sizes everywhere.

* Remove the redundant call to stat() in parseExprFromFile().
  The file cannot be a symlink because that's the exit condition
  of the loop before.
2010-10-04 17:55:38 +00:00
Eelco Dolstra bf87cc44b4 * Sync with the trunk. 2010-06-21 07:55:38 +00:00
Ludovic Courtès 8bcdd36f10 Add XML output to `nix-store'.
* src/nix-store/Makefile.am (nix_store_SOURCES): Add `xmlgraph.cc' and
  `xmlgraph.hh'.

* src/nix-store/help.txt (Operations): Document `--xml'.

* src/nix-store/nix-store.cc (opQuery): Handle `--xml'.

* src/nix-store/xmlgraph.cc, src/nix-store/xmlgraph.hh: New files.
2010-05-31 16:36:24 +00:00
Ludovic Courtès da52f8bea0 Comment out dead code in `nix-store'.
* src/nix-store/dotgraph.cc (pathLabel): Move within #if 0 section.
2010-05-31 16:36:20 +00:00
Eelco Dolstra f92c9a0ac5 * Allow unprivileged users to do `nix-store --clear-failed-paths' and
`nix-store --query-failed-paths'.
2010-05-04 10:45:10 +00:00
Eelco Dolstra ef337f7089 2010-04-26 12:58:12 +00:00
Eelco Dolstra 6199f9b93e * Added a command `nix-store --clear-failed-paths <PATHS>' to clear
the "failed" status of the given store paths.  The special value `*'
  clears all failed paths.
2010-04-26 12:56:42 +00:00
Eelco Dolstra 2398af13c5 * Add an command `nix-store --query-failed-paths' to list the cached
failed paths (when using the `build-cache-failure' option).
2010-04-26 12:43:42 +00:00
Eelco Dolstra f3b8833a48 * Drop the dependency on the ATerm library. 2010-04-19 14:51:58 +00:00
Eelco Dolstra 594eaddd11 * When using the included sqlite/aterm libraries, build with
--enable-shared.
* In libutil/libstore/libexpr etc., link against sqlite and aterm.
* Some more header file hygiene.
2010-03-02 15:58:13 +00:00
Eelco Dolstra fefd467539 * `helpText' is now zero-terminated. 2010-02-24 13:24:27 +00:00
Eelco Dolstra fae0427324 * ADDITIONAL_NETWORK_LIBS -> LIBS. 2010-02-24 12:25:48 +00:00
Eelco Dolstra fa6a4fcb11 * Add ${sqlite_lib} everywhere. Just adding it in `libstore' doesn't
work on x86_64 when sqlite is compiled statically.
2010-02-24 12:18:48 +00:00
Eelco Dolstra fdcaf37361 * Made `nix-store -qR --include-outputs' much faster if there are
multiple paths specified on the command line (from O(n * m) to O(n +
  m), where n is the number of arguments and m is the size of the
  closure).
2010-01-25 17:18:44 +00:00
Eelco Dolstra 9b8fda796b * Templatise getIntArg / string2Int. 2009-11-24 12:26:25 +00:00
Eelco Dolstra 3d55f1eb57 * A command `nix-store --query --roots <paths>' to find the garbage
collector roots that point (directly or indirectly) to the given
  paths.
2009-11-23 18:16:25 +00:00
Eelco Dolstra ae6bf87273 * `nix-store --gc --print-roots': also print the path of the actual
root symlink, not just its target.  E.g.:

  /nix/var/nix/profiles/system-99-link -> /nix/store/76kwf88657nq7wgk1hx3l1z5q91zb9wd-system
2009-11-23 17:23:12 +00:00
Eelco Dolstra 8824d60fe5 * Remove the --use-atime / --max-atime garbage collector flags. Many
(Linux) machines no longer maintain the atime because it's too
  expensive, and on the machines where --use-atime is useful (like the
  buildfarm), reading the atimes on the entire Nix store takes way too
  much time to make it practical.
2009-11-20 17:12:38 +00:00
Eelco Dolstra 327a232c85 * Remove support for old (before Nix 0.12pre12020) databases. 2009-11-06 01:15:44 +00:00
Sander van der Burg 53a4981fa2 Added optional parameter which adds -lnsl -lsocket to make the Nix package manager work on OpenSolaris 2009-10-08 14:50:37 +00:00
Eelco Dolstra 5dd8fb2069 * Don't use ULLONG_MAX in maxFreed - use 0 to mean "no limit".
18446744073709551615ULL breaks on GCC 3.3.6 (`integer constant is
  too large for "long" type').
2009-03-26 11:02:07 +00:00
Eelco Dolstra 7a57b2920b * Better error message when nix-store --import is applied to garbage
(previously it would likely say "implementation cannot deal with >
  32-bit integers").
2009-03-22 17:51:45 +00:00
Eelco Dolstra 77d272623f * NAR archives: handle files larger than 2^32 bytes. Previously it
would just silently store only (fileSize % 2^32) bytes.
* Use posix_fallocate if available when unpacking archives.
* Provide a better error message when trying to unpack something that
  isn't a NAR archive.
2009-03-22 17:36:43 +00:00
Eelco Dolstra 0008b0006d * Simplify deleting .lock files in /nix/store: just don't delete them
if they belong a path that's currently being built.  This gets rid
  of some Cygwin-specific code.
2008-12-12 17:03:18 +00:00
Eelco Dolstra ff762fb499 * Pass HashType values instead of strings. 2008-12-03 16:10:17 +00:00
Eelco Dolstra 64519cfd65 * Unify the treatment of sources copied to the store, and recursive
SHA-256 outputs of fixed-output derivations.  I.e. they now produce
  the same store path:

  $ nix-store --add x
  /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x

  $ nix-store --add-fixed --recursive sha256 x
  /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x

  the latter being the same as the path that a derivation

    derivation {
      name = "x";
      outputHashAlgo = "sha256";
      outputHashMode = "recursive";
      outputHash = "...";
      ...
    };

  produces.

  This does change the output path for such fixed-output derivations.
  Fortunately they are quite rare.  The most common use is fetchsvn
  calls with SHA-256 hashes.  (There are a handful of those is
  Nixpkgs, mostly unstable development packages.)
  
* Documented the computation of store paths (in store-api.cc).
2008-12-03 15:06:30 +00:00
Eelco Dolstra 5d250ad1ea * nix-store --dump-db: be more streamy. 2008-11-19 16:26:34 +00:00
Eelco Dolstra 2b7c839b4e * Typo. 2008-11-11 14:58:37 +00:00
Eelco Dolstra f32fef1b07 * GC option `--max-atime' that specifies an upper limit to the last
accessed time of paths that may be deleted.  Anything more recently
  used won't be deleted.  The time is specified in time_t,
  e.g. seconds since 1970-01-01 00:00:00 UTC; use `date +%s' to
  convert to time_t from the command line. 

  Example: to delete everything that hasn't been used in the last two
  months:

  $ nix-store --gc -v --max-atime $(date +%s -d "2 months ago")
2008-09-17 14:52:35 +00:00
Eelco Dolstra 77afd97a99 * nix-store --gc / --delete: show how many store paths were deleted. 2008-09-17 12:53:33 +00:00
Eelco Dolstra 7ab68961e4 * Garbage collector: added an option `--use-atime' to delete paths in
order of ascending last access time.  This is useful in conjunction
  with --max-freed or --max-links to prefer deleting non-recently used
  garbage, which is good (especially in the build farm) since garbage
  may become live again.

  The code could easily be modified to accept other criteria for
  ordering garbage by changing the comparison operator used by the
  priority queue in collectGarbage().
2008-09-17 10:02:55 +00:00
Eelco Dolstra a1d310b6b5 * `nix-store --realise': print what paths will be built/downloaded,
just like nix-env.
* `nix-store --realise': --dry-run option.
2008-08-04 13:44:46 +00:00
Eelco Dolstra d3aa183beb * Garbage collector: option `--max-freed' to stop after at least N
bytes have been freed, `--max-links' to stop when the Nix store
  directory has fewer than N hard links (the latter being important
  for very large Nix stores on filesystems with a 32000 subdirectories
  limit).
2008-06-18 14:20:16 +00:00
Eelco Dolstra a72709afd8 * Some refactoring: put the GC options / results in separate structs.
* The garbage collector now also prints the number of blocks freed.
2008-06-18 09:34:17 +00:00
Eelco Dolstra b0e92f6d47 * Merged the no-bdb branch (-r10900:HEAD
https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
2008-06-09 13:52:45 +00:00
Eelco Dolstra 66c51dc215 * nix-store --dump-db / --load-db to dump/load the Nix DB.
* nix-store --register-validity: option to supply the content hash of
  each path.
* Removed compatibility with Nix <= 0.7 stores.
2008-01-29 18:17:36 +00:00
Michael Raskin 3a2833daff corrected --help message for nix-store a bit 2007-12-10 22:16:47 +00:00
Eelco Dolstra 633518628f * nix-env -e: support uninstalling by path, so that one can say
$ nix-env -e $(which firefox)

  or

    $ nix-env -e /nix/store/nywzlygrkfcgz7dfmhm5xixlx1l0m60v-pan-0.132

* nix-env -i: if an argument contains a slash anywhere, treat it as a
  path and follow it through symlinks into the Nix store.  This allows
  things like

    $ nix-build -A firefox
    $ nix-env -i ./result

* nix-env -q/-i/-e: don't complain when the `*' selector doesn't match
  anything.  In particular, `nix-env -q \*' doesn't fail anymore on an
  empty profile.
2007-11-29 16:18:24 +00:00
Eelco Dolstra c05783ad67 * nix-store --import: add a flag --require-signature. 2007-11-16 16:10:27 +00:00
Eelco Dolstra 14e47e9c2c * Doh. 2007-10-10 14:58:00 +00:00
Eelco Dolstra 315183f194 * nix-store --optimise: flag "--dry-run" to just query what the disk
savings would be.
2007-10-10 13:43:04 +00:00
Eelco Dolstra a8629de827 * New command `nix-store --optimise' to reduce Nix store disk space
usage by finding identical files in the store and hard-linking them
  to each other.  It typically reduces the size of the store by
  something like 25-35%.  This is what the optimise-store.pl script
  did, but the new command is faster and more correct (it's safe wrt
  garbage collection and concurrent builds).
2007-10-09 22:14:27 +00:00
Eelco Dolstra 9e975458b4 * Get rid of the substitutes database table (NIX-47). Instead, if we
need any info on substitutable paths, we just call the substituters
  (such as download-using-manifests.pl) directly.  This means that
  it's no longer necessary for nix-pull to register substitutes or for
  nix-channel to clear them, which makes those operations much faster
  (NIX-95).  Also, we don't have to worry about keeping nix-pull
  manifests (in /nix/var/nix/manifests) and the database in sync with
  each other.

  The downside is that there is some overhead in calling an external
  program to get the substitutes info.  For instance, "nix-env -qas"
  takes a bit longer.

  Abolishing the substitutes table also makes the logic in
  local-store.cc simpler, as we don't need to store info for invalid
  paths.  On the downside, you cannot do things like "nix-store -qR"
  on a substitutable but invalid path (but nobody did that anyway).

* Never catch interrupts (the Interrupted exception).
2007-08-12 00:29:28 +00:00
Eelco Dolstra 6d1a1191b0 * Support queryDeriver() in multi-user installations. 2007-06-12 16:53:44 +00:00
Eelco Dolstra 7f6161ab3a * Flush cout to show progress. 2007-02-21 23:08:55 +00:00
Eelco Dolstra 0db450024d * Export/import many paths in one go. 2007-02-21 23:00:31 +00:00
Eelco Dolstra 9da367b7d5 * `nix-store -qR' and friends: print the paths sorted topologically
under the references relation.  This is useful for commands that
  want to copy paths to another Nix store in the right order.
2007-02-21 22:45:10 +00:00
Eelco Dolstra 881feb9698 * Flag --print-invalid' in nix-store --check-validity' to print out
which paths specified on the command line are invalid (i.e., don't
  barf when encountering an invalid path, just print it).  This is
  useful for build-remote.pl to figure out which paths need to be
  copied to a remote machine.  (Currently we use rsync, but that's
  rather inefficient.)
2007-02-21 17:57:59 +00:00
Eelco Dolstra 43c4d18c6a * nix-store --import': import an archive created by nix-store
--export' into the Nix store, and optionally check the cryptographic
  signatures against /nix/etc/nix/signing-key.pub.  (TODO: verify
  against a set of public keys.)
2007-02-21 15:45:32 +00:00
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).

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.
