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.
2010-01-29	* Don't consider a store path valid if its info file exists but is	Eelco Dolstra	1	-4/+36
	zero bytes long. That makes Nix more robust in case of crashes (especially on ext4).
2009-11-06	* Remove support for old (before Nix 0.12pre12020) databases.	Eelco Dolstra	1	-0/+12

2009-09-24	* And some more.	Eelco Dolstra	1	-0/+1

2009-09-23	* Darwin hack.	Eelco Dolstra	1	-0/+7

2009-09-23	* Create some state directories automatically as a convenience.	Eelco Dolstra	1	-6/+15

2009-06-13	* Canonicalise timestamps in the Nix store to 1 (1970-01-01 00:00:01	Eelco Dolstra	1	-1/+1
	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.
2009-04-21	* Use foreach in a lot of places.	Eelco Dolstra	1	-9/+8

2009-04-21	* nix-store --verify: don't bail out if a referenced path is missing.	Eelco Dolstra	1	-14/+13
	(It can't fix it though.)
2009-04-16	* Fix a few "comparison is always false/true due to limited range of	Eelco Dolstra	1	-1/+1
	data type" warnings on 64-bit platforms. The one in parser.y is likely to be a real bug.
2009-03-28	* Don't use the non-standard __gnu_cxx::stdio_filebuf class.	Eelco Dolstra	1	-25/+16

2009-03-27	* Create /nix/store if it doesn't exist.	Eelco Dolstra	1	-0/+2

2009-03-25	* Negative caching, i.e. caching of build failures. Disabled by	Eelco Dolstra	1	-0/+22
	default. This is mostly useful for Hydra.
2009-03-22	* NAR archives: handle files larger than 2^32 bytes. Previously it	Eelco Dolstra	1	-1/+1
	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.
2009-02-02	* Build hooks: use nix-store --import. This prevents a redundant	Eelco Dolstra	1	-1/+8
	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.
2008-12-16	* nix-store --verify: repair bad hash fields in the metadata file.	Eelco Dolstra	1	-4/+15

2008-12-03	* addToStore() in nix-worker: don't write the NAR dump received from	Eelco Dolstra	1	-19/+26
	the client to a temporary directory, as that is highly inefficient.
2008-12-03	* Pass HashType values instead of strings.	Eelco Dolstra	1	-3/+3

2008-12-03	* Made addToStore() a lot more efficient: it no longer reads the path	Eelco Dolstra	1	-32/+28
	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	* Unify the treatment of sources copied to the store, and recursive	Eelco Dolstra	1	-4/+7
	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).
2008-11-19	* Files in the info directory starting with "." are temporary files	Eelco Dolstra	1	-2/+5
	and don't indicate path validity.
2008-08-05	* Better error checking of the data from the substituters.	Eelco Dolstra	1	-21/+16

2008-08-04	* build.cc: only use a substituter if it returns info for a path.	Eelco Dolstra	1	-26/+32

2008-08-04	* nix-env --dry-run: show the total size of the substituter	Eelco Dolstra	1	-1/+4
	downloads.
2008-08-02	* Make nix-env --dry-run print the paths to be substituted correctly	Eelco Dolstra	1	-20/+97
	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.
2008-07-18	* Allow read-only access to the store (e.g., non-root users on NixOS	Eelco Dolstra	1	-5/+9
	can do operations like "nix-store -qR <path>" even without the Nix daemon).
2008-06-18	* Some refactoring: put the GC options / results in separate structs.	Eelco Dolstra	1	-2/+3
	* The garbage collector now also prints the number of blocks freed.
2008-06-09	* Merged the no-bdb branch (-r10900:HEAD	Eelco Dolstra	1	-566/+412
	https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
2008-03-01	* A transaction is unnecessary since the path cannot be	Eelco Dolstra	1	-8/+3
	garbage-collected (it's a temporary root).
2008-01-29	* nix-store --dump-db / --load-db to dump/load the Nix DB.	Eelco Dolstra	1	-93/+13
	* nix-store --register-validity: option to supply the content hash of each path. * Removed compatibility with Nix <= 0.7 stores.
2007-10-10	* Doh! Don't change the permissions on /nix/store.	Eelco Dolstra	1	-9/+8

2007-10-10	* nix-store --optimise: flag "--dry-run" to just query what the disk	Eelco Dolstra	1	-16/+21
	savings would be.
2007-10-09	* New command `nix-store --optimise' to reduce Nix store disk space	Eelco Dolstra	1	-5/+120
	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).
2007-08-13	* Bump the Nix database schema version number; delete the substitutes	Eelco Dolstra	1	-2/+30
	table.
2007-08-12	* Get rid of the substitutes database table (NIX-47). Instead, if we	Eelco Dolstra	1	-191/+42
	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).
2007-06-12	* Support queryDeriver() in multi-user installations.	Eelco Dolstra	1	-2/+8

2007-05-01	* Set a terminate() handler to ensure that we leave the BDB	Eelco Dolstra	1	-1/+5
	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	* Make --verify more interruptable.	Eelco Dolstra	1	-0/+1

2007-03-30	* Work around a bug in Apple's GCC preprocessor.	Eelco Dolstra	1	-1/+1

2007-03-01	* Look for the openssl program at compile time. If not found, call	Eelco Dolstra	1	-2/+2
	openssl through $PATH at runtime.
2007-03-01	* Don't check the signature unless we have to.	Eelco Dolstra	1	-21/+23

2007-02-27	* Doh! The deriver can be empty.	Eelco Dolstra	1	-1/+2

2007-02-21	* Check that the file containing the secret key is secret.	Eelco Dolstra	1	-1/+14

2007-02-21	* importPath(): set the deriver.	Eelco Dolstra	1	-3/+13
	* exportPath(): lock the path, use a transaction.
2007-02-21	* `nix-store --import': import an archive created by `nix-store	Eelco Dolstra	1	-4/+110
	--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.)
