Eelco Dolstra 5833243c92 * Create /nix/var/nix/db if it's missing. 2010-12-13 13:42:34 +00:00
Eelco Dolstra e4720b1a79 * Ignore the result of sqlite3_reset(). 2010-12-08 18:19:15 +00:00
Eelco Dolstra 8062d3af30 * `nix-store --verify --check-contents': don't hold the global GC lock
while checking the contents, since this operation can take a very
  long time to finish.  Also, fill in missing narSize fields in the DB
  while doing this.
2010-12-06 15:29:38 +00:00
Eelco Dolstra de79d23f76 * Retry a transaction if SQLite returns SQLITE_BUSY. This can happen
even with a very long busy timeout, because SQLITE_BUSY is also
  returned to resolve deadlocks.  This should get rid of random
  "database is locked" errors.  This is kind of hard to test though.
* Fix a horrible bug in deleteFromStore(): deletePathWrapped() should
  be called after committing the transaction, not before, because the
  commit might not succeed.
2010-12-05 18:23:19 +00:00
Eelco Dolstra bdf089f463 * Before a build, show the disk space that the downloaded store paths
will approximately require.
2010-11-17 14:31:42 +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 64fd29855a * Wrap deleteFromStore() in a transaction. Otherwise there might be a
race with other processes that add new referrers to a path,
  resulting in the garbage collector crashing with "foreign key
  constraint failed".  (Nix/4)
* Make --gc --print-dead etc. interruptible.
2010-10-14 15:55:51 +00:00
Eelco Dolstra e4907411c2 * Only do "pragma journal_mode = ..." if the current journal mode
differs from the desired mode.  There is an open SQLite ticket
  `Executing "PRAGMA journal_mode" may delete journal file while it is
  in use.'
2010-09-01 11:36:22 +00:00
Eelco Dolstra e2e168f7c2 `nix-store --verify' improvements:
* If a path has disappeared, check its referrers first, and don't try
  to invalidate paths that have valid referrers.  Otherwise we get a
  foreign key constraint violation.
* Read the whole Nix store directory instead of statting each valid
  path, which is slower.
* Acquire the global GC lock.
2010-08-31 11:47:31 +00:00
Eelco Dolstra 034f608e00 * Don't complain if the stored hash of a path is zero (unknown). 2010-08-24 14:25:33 +00:00
Eelco Dolstra fd9c77dfc7 * Use SQLite 3.7.0's write-ahead logging (WAL mode). This is a lot
faster than the old mode when fsyncs are enabled, because it only
  performs an fsync() when doing a checkpoint, rather than at every
  commit.  Some timings for doing a "nix-instantiate /etc/nixos/nixos
  -A system" after modifying the stdenv setup script:

    42.5s - SQLite 3.6.23 with truncate mode and fsync
     3.4s - SQLite 3.6.23 with truncate mode and no fsync
    32.1s - SQLite 3.7.0 with truncate mode and fsync
    16.8s - SQLite 3.7.0 with WAL mode and fsync, auto-checkpoint
            every 1000 pages
     8.3s - SQLite 3.7.0 with WAL mode and fsync, auto-checkpoint
            every 8192 pages
     1.7s - SQLite 3.7.0 with WAL mode and no fsync

  The default is now to use WAL mode with fsyncs.  Because WAL doesn't
  work on remote filesystems such as NFS (as it uses shared memory),
  truncate mode can be re-enabled by setting the "use-sqlite-wal"
  option to false.
2010-08-04 17:35:59 +00:00
Eelco Dolstra 3e5e0faf9c * Okay, putting a lock on the temporary directory used by importPath()
doesn't work because the garbage collector doesn't actually look at
  locks.  So r22253 was stupid.  Use addTempRoot() instead.  Also,
  locking the temporary directory in exportPath() was silly because it
  isn't even in the store.
2010-06-21 11:08:09 +00:00
Eelco Dolstra bf87cc44b4 * Sync with the trunk. 2010-06-21 07:55:38 +00:00
Eelco Dolstra b57189174f * In importPath() and exportPath(), lock the temporary directory to
prevent it from being deleted by the garbage collector.
2010-06-14 08:34:48 +00:00
Eelco Dolstra d1f6c0cbe3 * Replacing ValidPath rows doesn't work because it causes a constraint
violation of the Refs table.  So don't do that.
2010-06-08 13:38:28 +00:00
Eelco Dolstra aa45027818 * Sync with the trunk. 2010-05-12 22:13:09 +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 efc7a579e8 * Don't use the ATerm library for parsing/printing .drv files. 2010-04-19 13:46:58 +00:00
Eelco Dolstra 1a65142ec4 * Remove a debug statement. 2010-03-10 12:46:25 +00:00
Eelco Dolstra 4c356acd04 * In `nix-store --export', abort if the contents of a path has
changed.  This prevents corrupt paths from spreading to other
  machines.  Note that checking the hash is cheap because we're
  hashing anyway (because of the --sign feature).
2010-03-09 14:32:03 +00:00
Eelco Dolstra 2e4ef03aa3 * Increase the sqlite timeout. 2010-03-08 10:35:45 +00:00
Eelco Dolstra 3f9e647ae8 * checkInterrupt() shouldn't be called from a destructor. 2010-03-02 19:04:17 +00:00
Eelco Dolstra af565c348a * Support read-only access to the database. 2010-02-24 16:44:43 +00:00
Eelco Dolstra e33f67ff0b * Refactor the upgrade / database initialisation logic a bit. 2010-02-24 16:30:20 +00:00
Eelco Dolstra 84a4dd5ff0 * Don't use fdatasync since it doesn't work on Snow Leopard.
* Don't refer to config.h in util.hh, because config.h is not
  installed (http://hydra.nixos.org/build/303053).
2010-02-24 15:46:06 +00:00
Eelco Dolstra cfe742cfc5 * A function to query just the database id of a valid path. 2010-02-24 15:07:23 +00:00
Eelco Dolstra 9fd85c94de * Use `truncate' journal mode, which should be a bit faster. 2010-02-24 14:22:34 +00:00
Eelco Dolstra a3c63d0d6c * Disable fsync() in SQLite if the fsync-metadata option is set to
false.
* Change the default for `fsync-metadata' to true.
* Disable `fsync-metadata' in `make check'.
2010-02-24 13:12:57 +00:00
Eelco Dolstra 90b6352d0a * Do registerValidPaths() in one transaction, which is much faster.
E.g. it cuts the runtime of the referrers test from 50s to 23s.
2010-02-24 12:48:00 +00:00
Eelco Dolstra 462bd50aef * Use normal (rather than full) synchronous mode, which I gather from
the description at http://www.sqlite.org/atomiccommit.html should be
  safe enough.
2010-02-24 10:57:57 +00:00
Eelco Dolstra 2b20318b0e 2010-02-22 14:24:37 +00:00
Eelco Dolstra 9cda616949 * The database needs a trigger to get rid of self-references to
prevent a foreign key constraint violation on the Refs table when
  deleting a path.
2010-02-22 14:18:55 +00:00
Eelco Dolstra c4d388add4 * Get derivation outputs from the database instead of the .drv file,
which requires more I/O.
2010-02-22 12:44:36 +00:00
Eelco Dolstra 103cfee056 * Revert r19650 (implement gc-keep-outputs by looking for derivations
with the same name as the output) and instead use the
  DerivationOutputs table in the database, which is the correct way to
  to do things.
2010-02-22 11:44:17 +00:00
Eelco Dolstra 299ff64812 * Put the derivation outputs in the database. This is useful for the
garbage collector.
2010-02-22 11:15:50 +00:00
Eelco Dolstra 1930570ad9 * Foreign key support in SQLite is not a persistent setting, so enable
it at startup.
* Implement negative caching.  Now `make check' passes.
2010-02-19 17:15:22 +00:00
Eelco Dolstra 9c9a88e9e2 * Implement more stuff. 2010-02-19 16:43:25 +00:00
Eelco Dolstra 762cee72cc * Implement registerValidPath(). 2010-02-19 16:04:51 +00:00
Eelco Dolstra 268f9aaf28 * Implemented queryValidPaths() and verifyStore(). 2010-02-18 16:51:27 +00:00
Eelco Dolstra 836e5b6f57 * Implemented queryReferrers(). 2010-02-18 16:21:59 +00:00
Eelco Dolstra 77cb9e3fb1 * Implement queryPathInfo(). 2010-02-18 15:52:57 +00:00
Eelco Dolstra 885e22b16e * Implement isValidPath(). 2010-02-18 15:11:08 +00:00
Eelco Dolstra cfb09e0fad * Automatically abort transactions if they go out of scope without
committing.
2010-02-18 14:40:07 +00:00
Eelco Dolstra e0305bb7a8 * Some wrapper objects to ensure that SQLite objects are properly
destroyed.
2010-02-18 14:30:42 +00:00
Eelco Dolstra a053d2d8e5 * Add the deriver to the ValidPaths table. In principle we could now
store all the derivers of a path efficiently.  But that opens a big
  can of worms with respect to garbage collector semantics.
2010-02-18 13:48:18 +00:00
Eelco Dolstra dbddac0fe9 * Assign an integer id to every row in the ValidPaths table in order
to make the Refs table more space-efficient.  For instance, this
  reduces the size of the database on my laptop from 93 MiB to 18
  MiB.  (It was 72 MiB with the old schema on an ext3 disk with a 1
  KiB block size.)
2010-02-18 13:40:46 +00:00
Eelco Dolstra c1a07f9445 * Convert the Nix database to SQLite. 2010-02-18 13:16:59 +00:00
Eelco Dolstra 07ffdc2862 * Added an option "fsync-metadata" to fsync() changes to
/nix/var/nix/db.
* Removed the function writeStringToFile since it does (almost) the
  same thing as writeFile.
2010-01-29 12:22:58 +00:00
Eelco Dolstra ad529fb89f * Don't consider a store path valid if its info file exists but is
zero bytes long.  That makes Nix more robust in case of crashes
  (especially on ext4).
2010-01-29 11:53:58 +00:00
Eelco Dolstra 327a232c85 * Remove support for old (before Nix 0.12pre12020) databases. 2009-11-06 01:15:44 +00:00
Eelco Dolstra c7057fc1f2 * And some more. 2009-09-24 07:39:55 +00:00
Eelco Dolstra 676e07902e * Darwin hack. 2009-09-23 18:04:55 +00:00
Eelco Dolstra 64e89980e8 * Create some state directories automatically as a convenience. 2009-09-23 17:05:51 +00:00
Eelco Dolstra 14bc3ce3d6 * Canonicalise timestamps in the Nix store to 1 (1970-01-01 00:00:01
UTC) rather than 0 (00:00:00).  1 is a better choice because some
  programs use 0 as a special value.  For instance, the Template
  Toolkit uses a timestamp of 0 to denote the non-existence of a file,
  so it barfs on files in the Nix store (see
  template-toolkit-nix-store.patch in Nixpkgs).  Similarly, Maya 2008
  fails to load script directories with a timestamp of 0 and can't be
  patched because it's closed source.

  This will also shut up those "implausibly old time stamp" GNU tar
  warnings.
2009-06-13 16:30:58 +00:00
Eelco Dolstra d5eab2fc82 * Use foreach in a lot of places. 2009-04-21 11:52:16 +00:00
Eelco Dolstra 8f1bf28505 * nix-store --verify: don't bail out if a referenced path is missing.
(It can't fix it though.)
2009-04-21 11:06:27 +00:00
Eelco Dolstra 4e646b0ddb * Fix a few "comparison is always false/true due to limited range of
data type" warnings on 64-bit platforms.  The one in parser.y is
  likely to be a real bug.
2009-04-16 12:03:17 +00:00
Eelco Dolstra c7152c8f97 * Don't use the non-standard __gnu_cxx::stdio_filebuf class. 2009-03-28 19:41:53 +00:00
Eelco Dolstra cb85bc396e * Create /nix/store if it doesn't exist. 2009-03-27 14:19:04 +00:00
Eelco Dolstra 92f525ecf4 * Negative caching, i.e. caching of build failures. Disabled by
default.  This is mostly useful for Hydra.
2009-03-25 21:05:42 +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 b682fae9d9 * Build hooks: use nix-store --import. This prevents a redundant
scan for runtime dependencies (i.e. the local machine shouldn't do a
  scan that the remote machine has already done).  Also pipe directly
  into `nix-store --import': don't use a temporary file.
2009-02-02 17:24:10 +00:00
Eelco Dolstra 8fce03e0ad * nix-store --verify: repair bad hash fields in the metadata file. 2008-12-16 13:28:18 +00:00
Eelco Dolstra 82ae85de27 * addToStore() in nix-worker: don't write the NAR dump received from
the client to a temporary directory, as that is highly inefficient.
2008-12-03 18:05:14 +00:00
Eelco Dolstra ff762fb499 * Pass HashType values instead of strings. 2008-12-03 16:10:17 +00:00
Eelco Dolstra 1307b22223 * Made addToStore() a lot more efficient: it no longer reads the path
being copied 3 times in the worst case.  It doesn't run in constant space,
  but it didn't do that anyway.
2008-12-03 15:51:17 +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 e13da525a7 * Files in the info directory starting with "." are temporary files
and don't indicate path validity.
2008-11-19 16:27:07 +00:00
Eelco Dolstra 98b07466fb * Better error checking of the data from the substituters. 2008-08-05 10:57:53 +00:00
Eelco Dolstra 5adbb0aabe * build.cc: only use a substituter if it returns info for a path. 2008-08-04 13:15:35 +00:00
Eelco Dolstra c4f98941ed * nix-env --dry-run: show the total size of the substituter
downloads.
2008-08-04 12:29:04 +00:00
Eelco Dolstra 3c92ea399d * Make nix-env --dry-run print the paths to be substituted correctly
again.  (After the previous substituter mechanism refactoring I
  didn't update the code that obtains the references of substitutable
  paths.)  This required some refactoring: the substituter programs
  are now kept running and receive/respond to info requests via
  stdin/stdout.
2008-08-02 12:54:35 +00:00
Eelco Dolstra 989176c56e * Allow read-only access to the store (e.g., non-root users on NixOS
can do operations like "nix-store -qR <path>" even without the Nix
  daemon).
2008-07-18 15:34:46 +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 f789ea1d09 * A transaction is unnecessary since the path cannot be
garbage-collected (it's a temporary root).
2008-03-01 21:05:33 +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
Eelco Dolstra d04291cfab * Doh! Don't change the permissions on /nix/store. 2007-10-10 13:52:38 +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 3757ee589f * Bump the Nix database schema version number; delete the substitutes
table.
2007-08-13 11:37:39 +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 cbfac2fdcc * Set a terminate() handler to ensure that we leave the BDB
environment cleanly even when an exception is thrown from a
  destructor.  We still crash, but we don't take all other Nix
  processes with us.
2007-05-01 15:16:17 +00:00
Eelco Dolstra 644946feed * Make --verify more interruptable. 2007-05-01 13:21:05 +00:00
Eelco Dolstra ae7990cc88 * Work around a bug in Apple's GCC preprocessor. 2007-03-30 13:24:35 +00:00
Eelco Dolstra db1973d012 * Look for the openssl program at compile time. If not found, call
openssl through $PATH at runtime.
2007-03-01 13:30:46 +00:00
Eelco Dolstra b4a040e52b * Don't check the signature unless we have to. 2007-03-01 12:30:24 +00:00
Eelco Dolstra 2ea3bebc23 * Doh! The deriver can be empty. 2007-02-27 23:18:57 +00:00
Eelco Dolstra 65f195f4c7 * Check that the file containing the secret key is secret. 2007-02-21 17:51:10 +00:00
Eelco Dolstra dc7d594776 * importPath(): set the deriver.
* exportPath(): lock the path, use a transaction.
2007-02-21 16:23:25 +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.

Eelco Dolstra 46605fb4f5 * Fix 64-bit compiler warnings. 2007-02-06 20:03:53 +00:00
Eelco Dolstra b618fa6eb6 * computeStorePathForText: take the references into account when
computing the store path (NIX-77).  This is an important security
  property in multi-user Nix stores.

  Note that this changes the store paths of derivations (since the
  derivation aterms are added using addTextToStore), but not most
  outputs (unless they use builtins.toFile).

Eelco Dolstra 63f3ce6d9a * `nix-store --verify': revive checking the referrers table. This is
important to get garbage collection to work if there is any
  inconsistency in the database (because the referrer table is used to
  determine whether it is safe to delete a path).
* `nix-store --verify': show some progress.
2007-01-14 17:28:30 +00:00
Eelco Dolstra 8f67b35886 * Make the garbage collector more resilient to certain consistency
errors: in-use paths now cause a warning, not a fatal error.
2007-01-14 16:24:49 +00:00
Eelco Dolstra a3e6415ba8 * New primop builtins.filterSource, which can be used to filter files
from a source directory.  All files for which a predicate function
  returns true are copied to the store.  Typical example is to leave
  out the .svn directory:

    stdenv.mkDerivation {
      ...
      src = builtins.filterSource
        (path: baseNameOf (toString path) != ".svn")
        ./source-dir;
      # as opposed to
      #   src = ./source-dir;
    }

  This is important because the .svn directory influences the hash in
  a rather unpredictable and variable way.

Eelco Dolstra b17677462c * Use lchown() instead of chown() in canonicalisePathMetaData(). This
matters when running as root, since then we don't use the setuid
  helper (which already used lchown()).
  
* Also check for an obscure security problem on platforms that don't
  have lchown.  Then we can't change the ownership of symlinks, which
  doesn't matter *except* when the containing directory is writable by
  the owner (which is the case with the top-level Nix store directory).
2006-12-09 20:02:27 +00:00
Eelco Dolstra 5f681988f2 * Use deletePathWrapped() in more places. 2006-12-09 00:26:24 +00:00
Eelco Dolstra ec23ecc64d * In the garbage collector, if deleting a path fails, try to fix its
ownership, then try again.
2006-12-07 15:54:52 +00:00
Eelco Dolstra a0a43c3206 * When not running as root, call the setuid helper to change the
ownership of the build result after the build.
2006-12-07 15:18:14 +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 35247c4c9f * Removed `build-allow-root'.
* Added `build-users-group', the group under which builds are to be
  performed.
* Check that /nix/store has 1775 permission and is owner by the
  build-users-group.
2006-12-03 15:32:38 +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 b0d8e05be1 * More operations.
* addToStore() and friends: don't do a round-trip to the worker if
  we're only interested in the path (i.e., in read-only mode).
2006-12-01 18:00:01 +00:00
Eelco Dolstra 0565b5f2b3 * More remote operations.
* Added new operation hasSubstitutes(), which is more efficient than
  querySubstitutes().size() > 0.
2006-11-30 22:43:55 +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 9cf1948993 * Skeleton of remote store implementation. 2006-11-30 18:35:36 +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.
