2010-02-24* A function to query just the database id of a valid path.Eelco Dolstra
2010-02-24(no commit message)Eelco Dolstra
2010-02-24* Use `truncate' journal mode, which should be a bit faster.Eelco Dolstra
2010-02-24* Disable fsync() in SQLite if the fsync-metadata option is set toEelco Dolstra
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
E.g. it cuts the runtime of the referrers test from 50s to 23s.
2010-02-24* ADDITIONAL_NETWORK_LIBS -> LIBS.Eelco Dolstra
2010-02-24* Add ${sqlite_lib} everywhere. Just adding it in `libstore' doesn'tEelco Dolstra
work on x86_64 when sqlite is compiled statically.
2010-02-24* Use normal (rather than full) synchronous mode, which I gather fromEelco Dolstra
the description at http://www.sqlite.org/atomiccommit.html should be safe enough.

2010-02-23* configure: flag --with-sqlite.Eelco Dolstra

2010-02-22* The database needs a trigger to get rid of self-references toEelco Dolstra
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
which requires more I/O.
2010-02-22* Revert r19650 (implement gc-keep-outputs by looking for derivationsEelco Dolstra
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 theEelco Dolstra
garbage collector.
2010-02-19* Foreign key support in SQLite is not a persistent setting, so enableEelco Dolstra
it at startup. * Implement negative caching. Now `make check' passes.
2010-02-19* Implement more stuff.Eelco Dolstra
2010-02-19* Implement registerValidPath().Eelco Dolstra
2010-02-18* Implemented queryValidPaths() and verifyStore().Eelco Dolstra
2010-02-18* Implemented queryReferrers().Eelco Dolstra
2010-02-18* Implement queryPathInfo().Eelco Dolstra
2010-02-18* Implement isValidPath().Eelco Dolstra
2010-02-18* Automatically abort transactions if they go out of scope withoutEelco Dolstra
committing.
2010-02-18* Some wrapper objects to ensure that SQLite objects are properlyEelco Dolstra
destroyed.
2010-02-18* Add the deriver to the ValidPaths table. In principle we could nowEelco Dolstra
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 orderEelco Dolstra
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
2010-02-03* Revert r19797, and use a simpler solution: just don't monitor buildEelco Dolstra
hooks for silence. It's unnecessary because the remote nix-store command is already monitoring the real build.
2010-02-03* While waiting for a lock, print a sign of life every 5 minutes.Eelco Dolstra
This prevents remote builders from being killed by the `max-silent-time' inactivity monitor while they are waiting for a long garbage collection to finish. This happens fairly often in the Hydra build farm.
2010-02-02* Remove most Cygwin-specific code. Cygwin 1.7 implements advisoryEelco Dolstra
POSIX locks, and simulates Unix-style file deletion semantics sufficiently. Note that this means that Nix won't work on Cygwin 1.5 anymore.
2010-01-29* Added an option "fsync-metadata" to fsync() changes toEelco Dolstra
/nix/var/nix/db. * Removed the function writeStringToFile since it does (almost) the same thing as writeFile.
2010-01-29* Don't consider a store path valid if its info file exists but isEelco Dolstra
zero bytes long. That makes Nix more robust in case of crashes (especially on ext4).
2010-01-25* Made `nix-store -qR --include-outputs' much faster if there areEelco Dolstra
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* Make the garbage collector do the right thing when `gc-keep-outputs'Eelco Dolstra
is enabled by not depending on the deriver.
2009-12-17* Include config.h before the C library headers, because it definesEelco Dolstra
_FILE_OFFSET_BITS=64. Without it, functions like stat() fail on large file sizes. This happened with a Nix store on squashfs: $ nix-store --dump /tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds > /dev/null error: getting attributes of path `/tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds': Value too large for defined data type $ stat /tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds File: `/tmp/mnt/46wzqnk4cbdwh1dclhrpqnnz1icak6n7-local-net-cmds' Size: 0 Blocks: 36028797018963968 IO Block: 1024 regular empty file (This is a bug in squashfs or mksquashfs, but it shouldn't cause Nix to fail.)
2009-12-16* Build correctly against newer ATerm releases. Fixes "error: 'union'Eelco Dolstra
tag used in naming 'struct _ATerm'".
2009-12-09* Give a better error message when trying to build something andEelco Dolstra
readOnlyMode is set.
2009-11-24* Randomise the order in which we delete entries to make the collectorEelco Dolstra
less biased towards deleting paths that come alphabetically first (e.g. /nix/store/000...). This matters when using --max-freed etc.
2009-11-23(no commit message)Eelco Dolstra
2009-11-23* `nix-store --gc --print-roots': also print the path of the actualEelco Dolstra
root symlink, not just its target. E.g.: /nix/var/nix/profiles/system-99-link -> /nix/store/76kwf88657nq7wgk1hx3l1z5q91zb9wd-system
2009-11-23* Made the garbage collector a lot faster. It no longer computes theEelco Dolstra
complete set of live and dead paths before starting the actual deletion, but determines liveness on demand. I.e. for any path in the store, it first tries to delete all the referrers, and then the path itself. This means that the collector can start deleting paths almost immediately.
2009-11-20* Remove the --use-atime / --max-atime garbage collector flags. ManyEelco Dolstra
(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.
2009-11-06* Remove support for old (before Nix 0.12pre12020) databases.Eelco Dolstra
2009-10-22* When building in a chroot, make a copy of a file if hard-linkingEelco Dolstra
fails. This is likely to happen after a `nix-store --optimise', because some files may have 32000 links (NIX-111).
2009-10-22* Remove a prototype for a function that no longer exists.Eelco Dolstra
2009-10-08Added optional parameter which adds -lnsl -lsocket to make the Nix package ↵Sander van der Burg
manager work on OpenSolaris
2009-09-24* And some more.Eelco Dolstra
2009-09-24* Fix a build failure on Fedora 11. rename() needs <stdio.h>.Eelco Dolstra
2009-09-23* Darwin hack.Eelco Dolstra
2009-09-23* Create some state directories automatically as a convenience.Eelco Dolstra
