2013-02-05	Nix::Store::derivationFromPath: Return derivation outputs	Eelco Dolstra

2012-12-20	Give a better error message if writeFile fails due to permission issues	Eelco Dolstra

2012-11-23	nix-copy-closure: Add flag ‘--use-substitutes’	Eelco Dolstra

2012-10-17	nix-push: Only generate and copy a NAR if it doesn't already exist	Eelco Dolstra
	This prevents unnecessary and slow rebuilds of NARs that already exist in the binary cache.
2012-09-19	Support xz compression in the download-using-manifests substituter	Eelco Dolstra

2012-09-13	Delete manifests in "nix-channel --remove" or when a binary cache is available	Eelco Dolstra

2012-08-27	Drop dependency on List::MoreUtils	Eelco Dolstra

2012-08-27	Add missing file	Eelco Dolstra

2012-07-30	Refactor settings processing	Eelco Dolstra
	Put all Nix configuration flags in a Settings object.
2012-07-30	Pass configuration settings to the substituters	Eelco Dolstra
	Previously substituters could read nix.conf themselves, but this didn't take --option flags into account.
2012-07-18	Merge branch 'master' into no-manifests	Eelco Dolstra

2012-07-17	Add function queryPathFromHashPart()	Eelco Dolstra
	To implement binary caches efficiently, Hydra needs to be able to map the hash part of a store path (e.g. "gbg...zr7") to the full store path (e.g. "/nix/store/gbg...kzr7-subversion-1.7.5"). (The binary cache mechanism uses hash parts as a key for looking up store paths to ensure privacy.) However, doing a search in the Nix store for /nix/store/<hash>* is expensive since it requires reading the entire directory. queryPathFromHashPart() prevents this by doing a cheap database lookup.
2012-07-17	queryPathInfo(): return hash in base-32 if desired	Eelco Dolstra
	Cherry-picked from the no-manifests branch.
2012-07-11	Set the User-Agent header to "Nix/<version>"	Eelco Dolstra

2012-07-09	download-from-binary-cache: add nix.conf options	Eelco Dolstra

2012-07-02	nix-push: Always generate base-32 hashes	Eelco Dolstra

2012-06-29	First attempt at the manifest-less substituter	Eelco Dolstra

2012-06-29	Use XZ compression in binary caches	Eelco Dolstra
	XZ compresses significantly better than bzip2. Here are the compression ratios and execution times (using 4 cores in parallel) on my /var/run/current-system (3.1 GiB): bzip2: total compressed size 849.56 MiB, 30.8% [2m08] xz -6: total compressed size 641.84 MiB, 23.4% [6m53] xz -7: total compressed size 621.82 MiB, 22.6% [7m19] xz -8: total compressed size 599.33 MiB, 21.8% [7m18] xz -9: total compressed size 588.18 MiB, 21.4% [7m40] Note that compression takes much longer. More importantly, however, decompression is much faster: bzip2: 1m47.274s xz -6: 0m55.446s xz -7: 0m54.119s xz -8: 0m52.388s xz -9: 0m51.842s The only downside to using -9 is that decompression takes a fair amount (~65 MB) of memory.
2012-05-10	Support building with the Perl XS bindings disabled	Eelco Dolstra
	Since the Perl bindings require shared libraries, this is required on platforms such as Cygwin where we do a static build.
2012-04-13	nix-copy-closure: Move the progressViewer directly adjacent to the ssh call ↵	Shea Levy
	so that network progress is what's measured
2012-04-13	Add the '--show-progress' flag to nix-copy-closure	Shea Levy

2012-04-10	Unconfuse Rob	Eelco Dolstra

2012-03-19	Add a command "nix-build --run-env" to reproduce the environment of a derivation	Eelco Dolstra
	This command builds or fetches all dependencies of the given derivation, then starts a shell with the environment variables from the derivation. This shell also sources $stdenv/setup to initialise the environment further. The current directory is not changed. Thus this is a convenient way to reproduce a build environment in an existing working tree. Existing environment variables are left untouched (unless the derivation overrides them). As a special hack, the original value of $PATH is appended to the $PATH produced by $stdenv/setup. Example session: $ nix-build --run-env '<nixpkgs>' -A xterm (the dependencies of xterm are built/fetched...) $ tar xf $src $ ./configure $ make $ emacs (... hack source ...) $ make $ ./xterm
2012-03-05	nix-copy-closure: don't print copied path on stdout	Eelco Dolstra
	We're already printing progress on stderr, so printing them on stdout afterwards is kind of useless.
2012-03-05	Restore progress indication during nix-copy-closure	Eelco Dolstra

2012-01-03	* Sync with the trunk.	Eelco Dolstra

2012-01-03	* Ignore missing manifest symlinks.	Eelco Dolstra

2012-01-03	* Add a test for nix-channel.	Eelco Dolstra
	* Refactor the nix-channel unpacker a bit.
2011-12-02	* Add some more functions to the Perl bindings.	Eelco Dolstra

2011-11-29	* Don't require a specific Perl version.	Eelco Dolstra

2011-11-29	* download-using-manifests: use the Perl bindings.	Eelco Dolstra

2011-11-29	* For consistency with "nix-store -q --hash", produce hashes in	Eelco Dolstra
	base-32. (This affects Hydra manifests.)
2011-11-23	* Add an API function exportPaths() that provides the functionality of	Eelco Dolstra
	‘nix-store --export’. * Add a Perl module that provides the functionality of ‘nix-copy-closure --to’. This is used by build-remote.pl so it no longer needs to start a separate nix-copy-closure process. Also, it uses the Perl API to do the export, so it doesn't need to start a separate nix-store process either. As a result, nix-copy-closure and build-remote.pl should no longer fail on very large closures due to an "Argument list too long" error. (Note that having very many dependencies in a single derivation can still fail because the environment can become too large. Can't be helped though.)
2011-11-23	* build-remote.pl: drop a hard-coded reference to /nix/etc/nix.	Eelco Dolstra

2011-11-22	* Move initialisation of variables like nixConfDir from libmain to	Eelco Dolstra
	libstore so that the Perl bindings can use it as well. It's vital that the Perl bindings use the configuration file, because otherwise nix-copy-closure will fail with a ‘database locked’ message if the value of ‘use-sqlite-wal’ is changed from the default.
2011-11-16	* nix-pull: update the Nix manifest cache if necessary. Also, don't	Eelco Dolstra
	read the manifest just to check the version and print the number of paths. This makes nix-pull very fast for the cached cache (speeding up nixos-rebuild without the ‘--no-pull’ or ‘--fast’ options).
2011-11-16	* Don't decompress the manifests in /nix/var/nix/manifest. This saves	Eelco Dolstra
	disk space, and, since they're typically only decompressed once (to fill the manifest cache), doesn't make things slower.
2011-11-16	* Remove obsolete line.	Eelco Dolstra

2011-11-16	* Re-use prepared statements across insertions into the manifest cache	Eelco Dolstra
	DB. This speeds up creating the cache from 16.1s to 7.9s on my system.
2011-10-11	* Use the Store API bindings in nix-copy-closure.	Eelco Dolstra

2011-10-11	* Move SSH.pm.	Eelco Dolstra

2011-10-10	* Install NixManifest.pm, NixConfig.pm and GeneratePatches.pm under	Eelco Dolstra
	the Nix:: namespace.
2011-10-10	* Include the Nix Perl bindings in Nix itself. This will allow the	Eelco Dolstra
	bindings to be used in Nix's own Perl scripts. The only downside is that Perl XS and Automake/libtool don't really like each other, so building is a bit tricky.
