2007-09-17	* nix-env: allow ~/.nix-defexpr to be a directory. If it is, then the	Eelco Dolstra	1	-3/+8
	Nix expressions in that directory are combined into an attribute set {file1 = import file1; file2 = import file2; ...}, i.e. each Nix expression is an attribute with the file name as the attribute name. Also recurses into directories. * nix-env: removed the "--import" (-I) option which set the ~/.nix-defexpr symlink. * nix-channel: don't use "nix-env --import", instead symlink ~/.nix-defexpr/channels. So finally nix-channel --update doesn't override any default Nix expressions but combines with them. This means that you can have (say) a local Nixpkgs SVN tree and use it as a default for nix-env: $ ln -s .../path-to-nixpkgs-tree ~/.nix-defexpr/nixpkgs_svn and be subscribed to channels (including Nixpkgs) at the same time. (If there is any ambiguity, the -A flag can be used to disambiguate, e.g. "nix-env -i -A nixpkgs_svn.pan".)
2007-08-22	* nix-channel: supports users who don't have write permission to the	Eelco Dolstra	1	-12/+21
	manifests directory. In that case, we don't do a nix-pull, so the user gets pure source deployment. The directory /nix/var/nix/gcroots/per-user/$USER should be writable. (It's created automatically if /nix/var/nix/gcroots/per-user is writable, e.g. if it has 1777 permission.)
2007-08-12	* Get rid of the substitutes database table (NIX-47). Instead, if we	Eelco Dolstra	1	-4/+0
	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).
2007-08-10	* Enable nix-prefetch-url caching in nix-channel.	Eelco Dolstra	1	-0/+6

2007-08-09	* nix-prefetch-url: support caching. If the environment variable	Eelco Dolstra	1	-1/+2
	NIX_DOWNLOAD_CACHE is set, then nix-prefetch-url will store the hash and timestamp of downloaded files in the directory $NIX_DOWNLOAD_CACHE. This allows it to figure out if the file is still in the Nix store.
2007-05-02	(no commit message)	Eelco Dolstra	1	-1/+0

2007-05-01	* Give unpacked channels more sensible names than 0, 1, ... They now	Eelco Dolstra	1	-8/+9
	get the basename of the channel URL (e.g., nixpkgs-unstable). The top-level Nix expression of the channel is now an attribute set, the attributes of which are the individual channels (e.g., {nixpkgs_unstable = ...; strategoxt_unstable = ...}). This makes attribute paths ("nix-env -qaA" and "nix-env -iA") more sensible, e.g., "nix-env -iA nixpkgs_unstable.subversion".
2006-11-18	* Show more progress.	Eelco Dolstra	1	-1/+3

2006-09-25	* In `nix-channel --update', skip manifests that assume a Nix store at	Eelco Dolstra	1	-1/+2
	a different location than the user's. This makes channels usable as a source deployment mechanism for people who install Nix under non-standard prefixes. (NIX-57)
2006-09-25	* Clean up calls to system().	Eelco Dolstra	1	-6/+6

2006-05-08	* Remove old manifests in `nix-channel --update'.	Eelco Dolstra	1	-0/+8

2006-02-01	* Add @bindir@.	Eelco Dolstra	1	-1/+1

2005-04-07	* Get rid of fetchurl, we don't need it anymore.	Eelco Dolstra	1	-8/+8

2005-03-03	* Channel fix.	Eelco Dolstra	1	-1/+1

2005-02-17	* Fix nix-channel.	Eelco Dolstra	1	-19/+57
	* Add `--help' flag; fixes NIX-5. * Add `--remove' flag; fixes NIX-6. * Add `--list' flag.
2004-12-20	* Place manifests in /nix/var/nix/manifests.	Eelco Dolstra	1	-0/+0
	* Use the new patch downloader.
2004-12-20	* Sync with changed substitute mechanism.	Eelco Dolstra	1	-0/+4
	* Accept the NarHash line. * Clear substitutes in `nix-channel --update'.
2004-11-04	* Better error messages.	Eelco Dolstra	1	-4/+4

2004-10-20	* Register channels as roots of the garbage collector (in	Eelco Dolstra	1	-2/+19
	$(localstatedir)/nix/gcroots/channels). * In setuid installations, create gcroots/tmp and gcroots/channels group-writable.
2004-04-21	* Channels. These allow you to stay current with an evolving set of	Eelco Dolstra	1	-0/+115
	Nix expressions. To subscribe to a channel (needs to be done only once): nix-channel --add \ http://catamaran.labs.cs.uu.nl/dist/nix/channels/nixpkgs-unstable This just adds the given URL to ~/.nix-channels (which can also be edited manually). To update from all channels: nix-channel --update This fetches the latest expressions and pulls cache manifests. The default Nix expression (~/.nix-defexpr) is made to point to the conjunction of the expressions downloaded from all channels. So to update all installed derivations in the current user environment: nix-channel --update nix-env --upgrade '*' If you are really courageous, you can put this in a cronjob or something. You can subscribe to multiple channels. It is not entirely clear what happens when there are name clashes between derivations from different channels. From nix-env/main.cc it appears that the one with the lowest (highest?) hash will be used, which is pretty meaningless.
