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 6baa2a2f5e 2010-02-24 14:39:52 +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 fefd467539 * `helpText' is now zero-terminated. 2010-02-24 13:24:27 +00:00
Eelco Dolstra 21b134b4e5 2010-02-24 13:13:39 +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 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 5954eadf67 * Remove the fdatasync check since it's no longer needed. 2010-02-24 12:16:50 +00:00
Eelco Dolstra bb82310dba * Set the path to sqlite3 properly. 2010-02-24 11:06:17 +00:00
Eelco Dolstra 69d9df7fe6 * Don't fork so much. 2010-02-24 11:04:03 +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 8520de4720 * Include the sqlite tarball in the Nix tarball. 2010-02-24 10:48:57 +00:00
Eelco Dolstra dc6d1ec67e 2010-02-23 23:24:49 +00:00
Eelco Dolstra 63b09c5e41 2010-02-23 22:31:38 +00:00
Eelco Dolstra 0efc986ba1 * Sync with the trunk. 2010-02-23 22:14:33 +00:00
Eelco Dolstra b4e6d98fc3 * configure: flag --with-sqlite. 2010-02-23 22:12:46 +00:00
Eelco Dolstra 7db2831d3a * Use ATerm 2.5. 2010-02-23 16:17:21 +00:00
Eelco Dolstra 5ccb6f64f4 * Run ATerm's `make check'. 2010-02-23 12:26:35 +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 eaaa13ce47 * Experimental branch for using SQLite to store the Nix database. 2010-02-18 13:14:51 +00:00
Eelco Dolstra 68e55cd9da * Since Hydra now escapes +', =' and `?' to %NN in URIs, 
nix-prefetch-url should unescape them, because `%' is not a valid
  character in store path names.
 2010-02-16 00:10:39 +00:00
Eelco Dolstra 3b3e1025c3 * Typo. Reported by Peter Koppstein. 2010-02-12 10:50:30 +00:00
Ludovic Courtès 20186a4079 Don't rely on `PATH_MAX' on GNU. 2010-02-10 15:55:50 +00:00
Ludovic Courtès d0bf4adb1f Add `.gitignore'. 2010-02-10 15:55:46 +00:00
Eelco Dolstra e08dbff9a8 * Fix a broken link (reported by Bjorn Buckwalter). 2010-02-05 10:17:13 +00:00
Eelco Dolstra e1e91a3731 * Bump. 2010-02-04 15:46:04 +00:00
Eelco Dolstra 817f4f7908 * Grmbl. Timing-sensitive tests are evil. 2010-02-04 14:43:43 +00:00
Eelco Dolstra f36b7e7579 2010-02-04 14:00:47 +00:00
Eelco Dolstra 719cebcac2 * "Fix" incorrect help message. 2010-02-04 09:38:09 +00:00
