2012-07-18	Merge branch 'master' into no-manifests	Eelco Dolstra	2	-0/+12

2012-07-17	Add function queryPathFromHashPart()	Eelco Dolstra	2	-0/+12
	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	1	-2/+2
	Cherry-picked from the no-manifests branch.
2012-07-11	Set the User-Agent header to "Nix/<version>"	Eelco Dolstra	1	-0/+2

2012-07-09	download-from-binary-cache: add nix.conf options	Eelco Dolstra	1	-3/+3

2012-07-02	nix-push: Always generate base-32 hashes	Eelco Dolstra	1	-2/+2

2012-06-29	First attempt at the manifest-less substituter	Eelco Dolstra	1	-0/+1

2012-06-29	Use XZ compression in binary caches	Eelco Dolstra	1	-1/+2
	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	2	-2/+67
	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	1	-1/+1
	so that network progress is what's measured
2012-04-13	Add the '--show-progress' flag to nix-copy-closure	Shea Levy	1	-3/+4

2012-04-10	Unconfuse Rob	Eelco Dolstra	1	-2/+2

2012-03-19	Add a command "nix-build --run-env" to reproduce the environment of a derivation	Eelco Dolstra	2	-0/+43
	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	1	-1/+1
	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	1	-1/+0

2012-01-03	* Sync with the trunk.	Eelco Dolstra	1	-0/+1

2012-01-03	* Ignore missing manifest symlinks.	Eelco Dolstra	1	-0/+1

2012-01-03	* Add a test for nix-channel.	Eelco Dolstra	1	-0/+1
	* Refactor the nix-channel unpacker a bit.
2011-12-02	* Add some more functions to the Perl bindings.	Eelco Dolstra	2	-1/+48

2011-11-29	* Don't require a specific Perl version.	Eelco Dolstra	1	-1/+0

2011-11-29	* download-using-manifests: use the Perl bindings.	Eelco Dolstra	2	-1/+16

2011-11-29	* For consistency with "nix-store -q --hash", produce hashes in	Eelco Dolstra	1	-1/+1
	base-32. (This affects Hydra manifests.)
2011-11-23	* Add an API function exportPaths() that provides the functionality of	Eelco Dolstra	3	-1/+60
	‘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	1	-0/+1

2011-11-22	* Move initialisation of variables like nixConfDir from libmain to	Eelco Dolstra	1	-3/+1
	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	1	-4/+4
	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	1	-2/+8
	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	1	-1/+0

2011-11-16	* Re-use prepared statements across insertions into the manifest cache	Eelco Dolstra	1	-8/+12
	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	2	-11/+32

2011-10-11	* Move SSH.pm.	Eelco Dolstra	1	-0/+52

2011-10-10	* Install NixManifest.pm, NixConfig.pm and GeneratePatches.pm under	Eelco Dolstra	3	-0/+722
	the Nix:: namespace.
2011-10-10	* Include the Nix Perl bindings in Nix itself. This will allow the	Eelco Dolstra	2	-0/+152
	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.
