2007-04-27	* Package conflict resolution through priority levels. If there is a	Eelco Dolstra	2	-19/+45
	user environment collission between two packages due to overlapping file names, then a package with a higher priority will overwrite the symlinks of a package with a lower priority. E.g., $ nix-env --set-flag priority 5 gcc $ nix-env --set-flag priority 10 binutils gives gcc a higher priority than binutils (higher number = lower priority).
2007-04-27	* Allow conflicting packages to be kept in a user environment, and	Eelco Dolstra	2	-3/+11
	allow switching between them (NIX-80). Example: two versions of Pan: $ nix-env -q pan pan-0.128 pan-0.14.2.91 $ readlink $(which pan) /nix/store/l38jrbilw269drpjkx7kinhrxj6fjh59-pan-0.14.2.91/bin/pan At most one of them can be active any given time. Assuming than 0.14.2.91 is active, you can active 0.128 as follows: $ nix-env --set-flag active false pan-0.14.2.91 $ nix-env --set-flag active true pan-0.128 $ readlink $(which pan) /nix/store/nziqwnlzy7xl385kglxhg75pfl5i936n-pan-0.128/bin/pan More flags to follow.
2006-09-25	* Use "propagated-user-env-packages", not "propagated-build-inputs"	Eelco Dolstra	1	-1/+1
	for packages that should be propagated to the user environment.
2006-09-25	* Propagated packages now have lower priority; they are symlinked	Eelco Dolstra	1	-14/+39
	after the packages that have been explicitly installed, and collisions are ignored.
2006-08-22	* Revert unintentional commit.	Eelco Dolstra	1	-1/+1

2006-08-16	* `nix-instantiate --{eval\|parse}-only --xml': print an XML	Eelco Dolstra	1	-1/+1
	representation instead of an ATerm. * Indent XML output.
2006-08-07	* In nar.nix, path -> storePath, otherwise we get a collision between	Eelco Dolstra	2	-4/+6
	environment variable names on Cygwin (where they are case insensitive).
2006-05-12	* Support for srcdir != builddir (NIX-41).	Eelco Dolstra	3	-3/+3

2005-07-22	* Adhockery.	Eelco Dolstra	1	-0/+1

2005-05-01	* Be quiet when untarring a channel file.	Eelco Dolstra	1	-1/+1

2005-04-07	* Get rid of fetchurl, we don't need it anymore.	Eelco Dolstra	4	-40/+1

2005-04-07	* `nix-store --add-fixed' to preload the outputs of fixed-output	Eelco Dolstra	1	-7/+1
	derivations. This is mostly to simplify the implementation of nix-prefetch-{url, svn}, which now work properly in setuid installations. * Enforce valid store names in `nix-store --add / --add-fixed'.
2005-03-15	* Purify all corepkgs builders.	Eelco Dolstra	3	-15/+8

2005-03-15	* Use SHA-256 for nix-push.	Eelco Dolstra	2	-5/+4

2005-03-14	* Set NAR name to content hash; previous nix-push names were not	Eelco Dolstra	1	-1/+3
	unique. * Drop `hashAlgo' attribute in manifests; prefix hashes with the hash algorithm instead.
2005-03-07	* Automatically add propagated build inputs to user environments.	Eelco Dolstra	1	-1/+15
	Maybe this is a bad idea.
2005-01-25	* Really fix the substitute mechanism, i.e., ensure the closure	Eelco Dolstra	4	-21/+4
	invariant by registering references through the manifest. * Added a test for nix-pull.
2005-01-17	* Removed the `id' attribute hack.	Eelco Dolstra	2	-9/+18
	* Formalise the notion of fixed-output derivations, i.e., derivations for which a cryptographic hash of the output is known in advance. Changes to such derivations should not propagate upwards through the dependency graph. Previously this was done by specifying the hash component of the output path through the `id' attribute, but this is insecure since you can lie about it (i.e., you can specify any hash and then produce a completely different output). Now the responsibility for checking the output is moved from the builder to Nix itself. A fixed-output derivation can be created by specifying the `outputHash' and `outputHashAlgo' attributes, the latter taking values `md5', `sha1', and `sha256', and the former specifying the actual hash in hexadecimal or in base-32 (auto-detected by looking at the length of the attribute value). MD5 is included for compatibility but should be considered deprecated. * Removed the `drvPath' pseudo-attribute in derivation results. It's no longer necessary. * Cleaned up the support for multiple output paths in derivation store expressions. Each output now has a unique identifier (e.g., `out', `devel', `docs'). Previously there was no way to tell output paths apart at the store expression level. * `nix-hash' now has a flag `--base32' to specify that the hash should be printed in base-32 notation. * `fetchurl' accepts parameters `sha256' and `sha1' in addition to `md5'. * `nix-prefetch-url' now prints out a SHA-1 hash in base-32. (TODO: a flag to specify the hash.)
2004-12-20	* Place manifests in /nix/var/nix/manifests.	Eelco Dolstra	5	-271/+1
	* Use the new patch downloader.
2004-12-13	* Include the size of the bzipped archive (necessary for computing the	Eelco Dolstra	1	-4/+8
	cheapest download path), as well as the hash of the contents of the path (necessary for checking patch applicability).
2004-12-13	* Patch deployment. `download.pl' (intended to be used in the	Eelco Dolstra	1	-0/+218
	substitute mechanism) creates a store path by downloading full NAR archives and/or patches specified in the available manifests. Any combination of present paths, full downloads, and patches can be used to construct the target path. In particular, patches can be chained in sequence; and full NAR archives of the target path can be omitted (i.e., patch-only deployment is possible). A shortest path algorithm is used to find the smallest set of files to be downloaded (the edge weights are currently file sizes, but one can imagine taking the network speed to the various source into account). Patches are binary deltas between two store paths. To be precise, they are the output of the `bsdiff' program applied to the NAR archives obtained by dumping (`nix-store --dump') the two store paths. The advantage of diff'ing NAR archives (and not, say, doing file-by-file diffs) is that file renames/moves are handled automatically. The disadvantage is that we cannot optimise creation of unchanged files (by hard-linking).
2004-11-08	* Check exit status of pipe elements.	Eelco Dolstra	1	-0/+2

2004-10-25	* New language feature: with expressions.	Eelco Dolstra	1	-1/+1
	The expression `with E1; E2' evaluates to E2 with all bindings in the attribute set E1 substituted. E.g., with {x = 123;}; x evaluates to 123. That is, the attribute set E1 is in scope in E2. This is particularly useful when importing files containing lots definitions. E.g., instead of let { inherit (import ./foo.nix) a b c d e f; body = ... a ... f ...; } we can now say with import ./foo.nix; ... a ... f ... I.e., we don't have to say what variables should be brought into scope.
2004-09-19	* prevent collision on log directory	Niels Janssen	1	-1/+2

2004-06-21	* Adapted nix-pull to use the new substitute mechanism.	Eelco Dolstra	4	-1/+53

2004-04-21	* Dist error.	Eelco Dolstra	1	-1/+1

2004-04-21	* Channels. These allow you to stay current with an evolving set of	Eelco Dolstra	5	-5/+47
	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.
2004-04-14	* Use @storedir@, not @prefix@/store.	Eelco Dolstra	1	-1/+1

2004-04-06	* Make the creation of user environments much faster and more storage	Eelco Dolstra	1	-45/+66
	efficient by creating only a single symlink to entire directory trees unless a collission occurs.
2004-04-06	* Switched from wget to curl.	Eelco Dolstra	3	-13/+12
	* Made the dependencies on bzip2 and the shell explicit.
2004-03-15	* Make perl a dependency of Nix.	Eelco Dolstra	2	-2/+4

2004-02-04	* Fixed the old envpkgs filename.	Eelco Dolstra	1	-1/+1

2003-12-30	* RPM spec file.	Eelco Dolstra	3	-14/+14
	* Respect DESTDIR variable.
2003-11-24	* Bug fix. Hmm, I thought I'd fixed this before :-\|	Eelco Dolstra	1	-2/+2

2003-11-22	* Don't use a hard-coded path.	Eelco Dolstra	2	-1/+10

2003-11-22	* Fix nix-push.	Eelco Dolstra	7	-25/+22

2003-11-22	* Maintain integrity of the substitute and successor mappings when	Eelco Dolstra	4	-15/+14
	deleting a path in the store. * Allow absolute paths in Nix expressions. * Get nix-prefetch-url to work again. * Various other fixes.
2003-11-19	* nix-env: a tool to manage user environments.	Eelco Dolstra	2	-0/+81
	* Replace all directory reading code by a generic readDirectory() function.
2003-10-16	* Substitutes and nix-pull now work again.	Eelco Dolstra	1	-3/+3
	* Fixed a segfault caused by the buffering of stderr. * Fix now allows the specification of the full output path. This should be used with great care, since it by-passes the normal hash generation. * Incremented the version number to 0.4 (prerelease).
2003-10-16	* Get nix-push to work again.	Eelco Dolstra	1	-4/+4
	* Fixed svn:ignore on externals/.
2003-10-02	* Use passive FTP in wget.	Eelco Dolstra	1	-1/+1

2003-10-02	* Include the right files in a distribution.	Eelco Dolstra	2	-2/+2

2003-08-28	* Set a path.	Eelco Dolstra	1	-0/+2

2003-08-28	* nix-push generated invalid (old-style) slices.	Eelco Dolstra	1	-0/+2
	* nar.sh needs a path.
2003-08-15	* A script `nix-prefetch-url' to fetch a URL, place it in the Nix	Eelco Dolstra	1	-1/+10
	store, and print its hash.
2003-08-06	* `==' is not a valid operator.	Eelco Dolstra	1	-1/+1

2003-08-06	* Scan for wget and use the full path in fetchurl.sh.	Eelco Dolstra	1	-2/+2
	* Use nix-hash (not md5sum) in fetchurl.sh.
2003-07-30	* INSTALL_DATA -> INSTALL_PROGRAM to ensure that the execute bit	Eelco Dolstra	2	-3/+3
	remains set.
2003-07-23	* Incorporated Berkeley DB and ATerm into the source tree.	Eelco Dolstra	2	-0/+4
	* `make dist'.
2003-07-22	* Substitutes now should produce a path with the same id as they are	Eelco Dolstra	1	-0/+1
	substituting for (obvious, really). * For greater efficiency, nix-pull/unnar will place the output in a path that is probably the same as what is actually needed, thus preventing a path copy. * Even if a output id is given in a Fix package expression, ensure that the resulting Nix derive expression has a different id. This is because Nix expressions that are semantically equivalent (i.e., build the same result) might be different w.r.t. efficiency or divergence. It is absolutely vital for the substitute mechanism that such expressions are not used interchangeably.
