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.
