2008-09-17	* Garbage collector: added an option `--use-atime' to delete paths in	Eelco Dolstra	1	-17/+10
	order of ascending last access time. This is useful in conjunction with --max-freed or --max-links to prefer deleting non-recently used garbage, which is good (especially in the build farm) since garbage may become live again. The code could easily be modified to accept other criteria for ordering garbage by changing the comparison operator used by the priority queue in collectGarbage().
2008-08-04	* `nix-store --realise': print what paths will be built/downloaded,	Eelco Dolstra	1	-13/+16
	just like nix-env. * `nix-store --realise': --dry-run option.
2008-06-18	* Garbage collector: option `--max-freed' to stop after at least N	Eelco Dolstra	1	-1/+7
	bytes have been freed, `--max-links' to stop when the Nix store directory has fewer than N hard links (the latter being important for very large Nix stores on filesystems with a 32000 subdirectories limit).
2008-06-18	* Some refactoring: put the GC options / results in separate structs.	Eelco Dolstra	1	-28/+29
	* The garbage collector now also prints the number of blocks freed.
2008-06-09	* Merged the no-bdb branch (-r10900:HEAD	Eelco Dolstra	2	-13/+12
	https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
2008-01-29	* nix-store --dump-db / --load-db to dump/load the Nix DB.	Eelco Dolstra	1	-11/+46
	* nix-store --register-validity: option to supply the content hash of each path. * Removed compatibility with Nix <= 0.7 stores.
2007-12-10	corrected --help message for nix-store a bit	Michael Raskin	1	-2/+7

2007-11-29	* nix-env -e: support uninstalling by path, so that one can say	Eelco Dolstra	1	-24/+12
	$ nix-env -e $(which firefox) or $ nix-env -e /nix/store/nywzlygrkfcgz7dfmhm5xixlx1l0m60v-pan-0.132 * nix-env -i: if an argument contains a slash anywhere, treat it as a path and follow it through symlinks into the Nix store. This allows things like $ nix-build -A firefox $ nix-env -i ./result * nix-env -q/-i/-e: don't complain when the `' selector doesn't match anything. In particular, `nix-env -q \' doesn't fail anymore on an empty profile.
2007-11-16	* nix-store --import: add a flag --require-signature.	Eelco Dolstra	1	-2/+7

2007-10-10	* Doh.	Eelco Dolstra	1	-1/+1

2007-10-10	* nix-store --optimise: flag "--dry-run" to just query what the disk	Eelco Dolstra	1	-2/+5
	savings would be.
2007-10-09	* New command `nix-store --optimise' to reduce Nix store disk space	Eelco Dolstra	2	-3/+50
	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).
2007-08-12	* Get rid of the substitutes database table (NIX-47). Instead, if we	Eelco Dolstra	2	-66/+2
	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/+2

2007-02-21	* Flush cout to show progress.	Eelco Dolstra	1	-1/+1

2007-02-21	* Export/import many paths in one go.	Eelco Dolstra	1	-3/+8

2007-02-21	* `nix-store -qR' and friends: print the paths sorted topologically	Eelco Dolstra	1	-38/+5
	under the references relation. This is useful for commands that want to copy paths to another Nix store in the right order.
2007-02-21	* Flag `--print-invalid' in `nix-store --check-validity' to print out	Eelco Dolstra	1	-3/+14
	which paths specified on the command line are invalid (i.e., don't barf when encountering an invalid path, just print it). This is useful for build-remote.pl to figure out which paths need to be copied to a remote machine. (Currently we use rsync, but that's rather inefficient.)
2007-02-21	* `nix-store --import': import an archive created by `nix-store	Eelco Dolstra	1	-0/+12
	--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.)
2007-02-21	* `nix-store --export --sign': sign the Nix archive using the RSA key	Eelco Dolstra	1	-3/+7
	in /nix/etc/nix/signing-key.sec
2007-02-20	* Start of `nix-store --export' operation for serialising a store	Eelco Dolstra	1	-0/+11
	path. This is like `nix-store --dump', only it also dumps the meta-information of the store path (references, deriver). Will add a `--sign' flag later to add a cryptographic signature, which we will use for exchanging store paths between build farm machines in a secure manner.
2007-01-13	* nix-pack-closure: store the top-level store paths in the closure.	Eelco Dolstra	1	-1/+9
	* nix-unpack-closure: extract the top-level paths from the closure and print them on stdout. This allows them to be installed, e.g., "nix-env -i $(nix-unpack-closure)". (NIX-64)
2006-12-07	* Doh!	Eelco Dolstra	1	-1/+1

2006-12-07	* Rename all those main.cc files.	Eelco Dolstra	2	-1/+1

2006-12-05	* Allow unprivileged users to run the garbage collector and to do	Eelco Dolstra	1	-3/+2
	`nix-store --delete'. But unprivileged users are not allowed to ignore liveness. * `nix-store --delete --ignore-liveness': ignore the runtime roots as well.
2006-12-02	* Remove SwitchToOriginalUser, we're not going to need it anymore.	Eelco Dolstra	1	-1/+0

2006-12-01	* Merge addToStore and addToStoreFixed.	Eelco Dolstra	1	-1/+1
	* addToStore now adds unconditionally, it doesn't use readOnlyMode. Read-only operation is up to the caller (who can call computeStorePathForPath).
2006-11-30	* Skeleton of the privileged worker program.	Eelco Dolstra	1	-23/+2
	* Some refactoring: put the NAR archive integer/string serialisation code in a separate file so it can be reused by the worker protocol implementation.
2006-11-30	* Put building in the store API.	Eelco Dolstra	1	-4/+3

2006-11-30	* Refactoring. There is now an abstract interface class StoreAPI	Eelco Dolstra	2	-14/+15
	containing functions that operate on the Nix store. One implementation is LocalStore, which operates on the Nix store directly. The next step, to enable secure multi-user Nix, is to create a different implementation RemoteStore that talks to a privileged daemon process that uses LocalStore to perform the actual operations.
2006-11-18	* Turn off synchronisation between C and C++ I/O functions. This	Eelco Dolstra	1	-1/+1
	gives a huge speedup in operations that read or write from standard input/output. (So libstdc++'s I/O isn't that bad, you just have to call std::ios::sync_with_stdio(false).) For instance, `nix-store --register-substitutes' went from 1.4 seconds to 0.1 seconds on a certain input. Another victory for Valgrind.
2006-11-13	* Option `--reregister' in `nix-store --register-validity'. We need	Eelco Dolstra	1	-8/+18
	this in the NixOS installer (or in the buildfarm) to ensure that the cryptographic hash of the path contents still matches the actual contents.
2006-10-28	* `nix-store --read-log / -l PATH' shows the build log of PATH, if	Eelco Dolstra	2	-3/+39
	available. For instance, $ nix-store -l $(which svn) \| less lets you read the build log of the Subversion instance in your profile. * `nix-store -qb': if applied to a non-derivation, take the deriver.
2006-10-05	* Documented nix-store --dump / --restore.	Eelco Dolstra	1	-1/+1

2006-09-21	* GC options in nix-store --help (NIX-15).	Eelco Dolstra	1	-1/+10

2006-09-05	* Sone missing #includes.	Eelco Dolstra	1	-1/+1

2006-09-04	* Use a proper namespace.	Eelco Dolstra	3	-4/+26
	* Optimise header file usage a bit. * Compile the parser as C++.
2006-08-11	* `nix-store --gc --print-dead': print the total size of the store	Eelco Dolstra	1	-5/+10
	objects that would be freed.
2006-05-12	* Support for srcdir != builddir (NIX-41).	Eelco Dolstra	1	-1/+2

2006-03-06	* `nix-env (-i\|-u) --dry-run' now shows exactly which missing paths	Eelco Dolstra	1	-0/+1
	will be built or substituted.
2006-03-06	* Regularise help text a bit.	Eelco Dolstra	1	-1/+1

2006-03-01	* db.hh shouldn't depend on the Berkeley DB headers.	Eelco Dolstra	1	-0/+2

2006-03-01	* Uninitialised variable. Fixes the --delete test.	Eelco Dolstra	1	-1/+1

2006-02-16	* A simple hack to fix NIX-18: the garbage collector cannot run when	Eelco Dolstra	1	-1/+1
	the disk is full (because to delete something from the Nix store, we need a Berkeley DB transaction, which takes up disk space). Under normal operation, we make sure that there exists a file /nix/var/nix/db/reserved of 1 MB. When running the garbage collector, we delete that file before we open the Berkeley DB environment.
2006-01-19	* Don't show cycles, they're not very useful.	Eelco Dolstra	1	-2/+4

2005-12-23	* Added a flag `--ignore-liveness' to `nix-store --delete'. It	Eelco Dolstra	1	-3/+8
	deletes a path even if it is reachable from a root. However, it won't delete a path that still has referrers (since that would violate store invariants). Don't try this at home. It's a useful hack for recovering from certain situations in a somewhat clean way (e.g., holes in closures due to disk corruption).
2005-12-23	* Revived the old "nix-store --delete" operation that deletes the	Eelco Dolstra	2	-1/+23
	specified paths from the Nix store. However, this operation is safe: it refuses to delete anything that the garbage collector wouldn't delete.
2005-12-15	* `nix-store --gc' prints out the number of bytes freed on stdout	Eelco Dolstra	1	-1/+16
	(even when it is interrupted by a signal).
2005-12-13	* Change `referer' to `referrer' throughout. In particular, the	Eelco Dolstra	2	-10/+10
	nix-store query options `--referer' and `--referer-closure' have been changed to `--referrer' and `--referrer-closure' (but the old ones are still accepted for compatibility).
2005-07-22	* Build dynamic libraries.	Eelco Dolstra	1	-2/+2
