| 2010-12-13 | * Create /nix/var/nix/db if it's missing. | Eelco Dolstra | 1 | -0/+1 | |
| 2010-12-08 | * Ignore the result of sqlite3_reset(). | Eelco Dolstra | 1 | -3/+4 | |
| 2010-12-06 | * `nix-store --verify --check-contents': don't hold the global GC lock | Eelco Dolstra | 1 | -11/+46 | |
| 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. | |||||
| 2010-12-05 | * Retry a transaction if SQLite returns SQLITE_BUSY. This can happen | Eelco Dolstra | 1 | -61/+83 | |
| 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. | |||||
| 2010-11-17 | * Before a build, show the disk space that the downloaded store paths | Eelco Dolstra | 1 | -0/+1 | |
| will approximately require. | |||||
| 2010-11-17 | * Add an operation `nix-store -q --size'. | Eelco Dolstra | 1 | -2/+12 | |
| 2010-11-16 | * Store the size of a store path in the database (to be precise, the | Eelco Dolstra | 1 | -26/+46 | |
| size of the NAR serialisation of the path, i.e., `nix-store --dump PATH'). This is useful for Hydra. | |||||
| 2010-10-14 | * Wrap deleteFromStore() in a transaction. Otherwise there might be a | Eelco Dolstra | 1 | -5/+8 | |
| 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. | |||||
| 2010-09-01 | * Only do "pragma journal_mode = ..." if the current journal mode | Eelco Dolstra | 1 | -1/+10 | |
| differs from the desired mode. There is an open SQLite ticket `Executing "PRAGMA journal_mode" may delete journal file while it is in use.' | |||||
| 2010-08-31 | `nix-store --verify' improvements: | Eelco Dolstra | 1 | -16/+53 | |
| * 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. | |||||
| 2010-08-24 | * Don't complain if the stored hash of a path is zero (unknown). | Eelco Dolstra | 1 | -2/+3 | |
| 2010-08-04 | * Use SQLite 3.7.0's write-ahead logging (WAL mode). This is a lot | Eelco Dolstra | 1 | -2/+12 | |
| 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. | |||||
| 2010-06-21 | * Okay, putting a lock on the temporary directory used by importPath() | Eelco Dolstra | 1 | -6/+18 | |
| 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 | * Sync with the trunk. | Eelco Dolstra | 1 | -0/+4 | |
| 2010-06-14 | * In importPath() and exportPath(), lock the temporary directory to | Eelco Dolstra | 1 | -0/+4 | |
| prevent it from being deleted by the garbage collector. | |||||
| 2010-06-08 | * Replacing ValidPath rows doesn't work because it causes a constraint | Eelco Dolstra | 1 | -2/+5 | |
| violation of the Refs table. So don't do that. | |||||
| 2010-05-12 | * Sync with the trunk. | Eelco Dolstra | 1 | -4/+1 | |
| 2010-04-26 | * Added a command `nix-store --clear-failed-paths <PATHS>' to clear | Eelco Dolstra | 1 | -0/+17 | |
| the "failed" status of the given store paths. The special value `*' clears all failed paths. | |||||
| 2010-04-26 | * Add an command `nix-store --query-failed-paths' to list the cached | Eelco Dolstra | 1 | -0/+21 | |
| failed paths (when using the `build-cache-failure' option). | |||||
| 2010-04-19 | * Don't use the ATerm library for parsing/printing .drv files. | Eelco Dolstra | 1 | -2/+0 | |
| 2010-03-10 | * Remove a debug statement. | Eelco Dolstra | 1 | -1/+0 | |
| 2010-03-09 | * In `nix-store --export', abort if the contents of a path has | Eelco Dolstra | 1 | -6/+17 | |
| 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). | |||||
| 2010-03-08 | * Increase the sqlite timeout. | Eelco Dolstra | 1 | -1/+1 | |
| 2010-03-02 | * checkInterrupt() shouldn't be called from a destructor. | Eelco Dolstra | 1 | -1/+1 | |
| 2010-02-24 | * Support read-only access to the database. | Eelco Dolstra | 1 | -1/+5 | |
| 2010-02-24 | * Refactor the upgrade / database initialisation logic a bit. | Eelco Dolstra | 1 | -56/+61 | |
| 2010-02-24 | * Don't use fdatasync since it doesn't work on Snow Leopard. | Eelco Dolstra | 1 | -2/+2 | |
| * Don't refer to config.h in util.hh, because config.h is not installed (http://hydra.nixos.org/build/303053). | |||||
| 2010-02-24 | * A function to query just the database id of a valid path. | Eelco Dolstra | 1 | -16/+20 | |
| 2010-02-24 | * Use `truncate' journal mode, which should be a bit faster. | Eelco Dolstra | 1 | -0/+4 | |
| 2010-02-24 | * Disable fsync() in SQLite if the fsync-metadata option is set to | Eelco Dolstra | 1 | -5/+7 | |
| false. * Change the default for `fsync-metadata' to true. * Disable `fsync-metadata' in `make check'. | |||||
| 2010-02-24 | * Do registerValidPaths() in one transaction, which is much faster. | Eelco Dolstra | 1 | -29/+9 | |
| E.g. it cuts the runtime of the referrers test from 50s to 23s. | |||||
| 2010-02-24 | * Use normal (rather than full) synchronous mode, which I gather from | Eelco Dolstra | 1 | -0/+4 | |
| the description at http://www.sqlite.org/atomiccommit.html should be safe enough. | |||||
| 2010-02-22 | (no commit message) | Eelco Dolstra | 1 | -4/+0 | |
| 2010-02-22 | * The database needs a trigger to get rid of self-references to | Eelco Dolstra | 1 | -2/+10 | |
| prevent a foreign key constraint violation on the Refs table when deleting a path. | |||||
| 2010-02-22 | * Get derivation outputs from the database instead of the .drv file, | Eelco Dolstra | 1 | -0/+24 | |
| which requires more I/O. | |||||
| 2010-02-22 | * Revert r19650 (implement gc-keep-outputs by looking for derivations | Eelco Dolstra | 1 | -0/+24 | |
| 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 | * Put the derivation outputs in the database. This is useful for the | Eelco Dolstra | 1 | -2/+24 | |
| garbage collector. | |||||
| 2010-02-19 | * Foreign key support in SQLite is not a persistent setting, so enable | Eelco Dolstra | 1 | -2/+19 | |
| it at startup. * Implement negative caching. Now `make check' passes. | |||||
| 2010-02-19 | * Implement more stuff. | Eelco Dolstra | 1 | -52/+45 | |
| 2010-02-19 | * Implement registerValidPath(). | Eelco Dolstra | 1 | -111/+90 | |
| 2010-02-18 | * Implemented queryValidPaths() and verifyStore(). | Eelco Dolstra | 1 | -117/+34 | |
| 2010-02-18 | * Implemented queryReferrers(). | Eelco Dolstra | 1 | -30/+18 | |
| 2010-02-18 | * Implement queryPathInfo(). | Eelco Dolstra | 1 | -49/+46 | |
| 2010-02-18 | * Implement isValidPath(). | Eelco Dolstra | 1 | -149/+95 | |
| 2010-02-18 | * Automatically abort transactions if they go out of scope without | Eelco Dolstra | 1 | -6/+37 | |
| committing. | |||||
| 2010-02-18 | * Some wrapper objects to ensure that SQLite objects are properly | Eelco Dolstra | 1 | -45/+73 | |
| destroyed. | |||||
| 2010-02-18 | * Add the deriver to the ValidPaths table. In principle we could now | Eelco Dolstra | 1 | -12/+19 | |
| 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 | * Assign an integer id to every row in the ValidPaths table in order | Eelco Dolstra | 1 | -2/+16 | |
| 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 | * Convert the Nix database to SQLite. | Eelco Dolstra | 1 | -12/+107 | |
| 2010-01-29 | * Added an option "fsync-metadata" to fsync() changes to | Eelco Dolstra | 1 | -6/+12 | |
| /nix/var/nix/db. * Removed the function writeStringToFile since it does (almost) the same thing as writeFile. | |||||
