2004-03-12	* Set the NIX_STORE and NIX_BUILD_TOP environment variables in	Eelco Dolstra	3	-3/+19
	builders to point to the store and the temporary build directory, respectively. Useful for purity checking. * Also set TEMPDIR, TMPDIR, TEMP, and TEMP to NIX_BUILD_TOP to make sure that tools in the builder store temporary files in the right location.
2004-02-19	* Resolve an ambiguity between ifs and attribute selection, e.g., `if	Eelco Dolstra	1	-3/+7
	b then x else y.z'.
2004-02-16	* Allow linking against an external Berkeley DB / ATerm library.	Eelco Dolstra	8	-15/+13

2004-02-16	* Allow the location of the store to be specified (--with-store-dir).	Eelco Dolstra	2	-2/+2
	* Do not create stuff in localstatedir when doing `make install' (since we may not have write access). In general, installation of constant code/data should be separate from the initialisation of mutable state.
2004-02-16	* Inherited attributes in recursive attribute sets are in scope of the	Eelco Dolstra	2	-10/+18
	non-inherited attributes.
2004-02-14	* The environment variable NIX_ROOT can now be set to execute Nix in a	Eelco Dolstra	4	-12/+70
	chroot() environment. * A operation `--validpath' to register path validity. Useful for bootstrapping in a pure Nix environment. * Safety checks: ensure that files involved in store operations are in the store.
2004-02-13	* Regression fix: realise substitutes and detect cycles.	Eelco Dolstra	1	-1/+8

2004-02-11	* When creating a new generation, also make the normal form of the	Eelco Dolstra	3	-6/+10
	derivation (i.e., the closure store expression) a root of the garbage collector. This ensures that running `nix-collect-garbage --no-successors' is safe.
2004-02-10	* Lots of manual stuff. Reference pages for most Nix commands.	Eelco Dolstra	1	-1/+1
	* nix-pull now requires the full url to the manifest, i.e., `/MANIFEST/' is no longer automatically appended. * nix-prefetch-url works again.
2004-02-10	* Print what generation we are switching to; honour --dry-run flag.	Eelco Dolstra	1	-0/+5

2004-02-09	* In `--upgrade': added flags `--lt', `--leq', `--always' to specify	Eelco Dolstra	4	-24/+81
	whether we want to upgrade if the current version is less than the available version (default), when it is less or equal, or always. * Added a flag `--dry-run' to show what would happen in `--install', `--uninstall', and `--upgrade', without actually performing the operation.
2004-02-08	* A command `--switch-generation' to switch to a specific generation	Eelco Dolstra	3	-0/+71
	of the current profile, e.g., $ nix-env --list-generations ... 39 2004-02-02 17:53:53 40 2004-02-02 17:55:18 41 2004-02-02 17:55:41 42 2004-02-02 17:55:50 (current) $ nix-env --switch-generation 39 $ ls -l /nix/var/nix/profiles/default ... default -> default-39-link * Also a command `--rollback' which is just a convenience operation to rollback to the oldest generation younger than the current one. Note that generations properly form a tree. E.g., if after switching to generation 39, we perform an installation action, a generation 43 is created which is a descendant of 39, not 42. So a rollback from 43 ought to go back to 39. This is not currently implemented; generations form a linear sequence.
2004-02-06	* In `--list-generations', show what the current generation is.	Eelco Dolstra	3	-13/+30

2004-02-06	* A command `--list-generations' to show all generations for a	Eelco Dolstra	3	-9/+80
	profile.
2004-02-06	* More refactoring.	Eelco Dolstra	4	-57/+74

2004-02-06	* Refactoring.	Eelco Dolstra	4	-131/+152

2004-02-06	* Use the profile pointed to by ~/.nix-profile if no --profile	Eelco Dolstra	2	-7/+12
	argument is specified.
2004-02-06	* Improvements to profiles. Generations are now per-profile, e.g.,	Eelco Dolstra	4	-47/+51
	default -> default-94-link default-82-link -> /nix/store/cc4480... default-83-link -> /nix/store/caeec8... ... default-94-link -> /nix/store/2896ca... experimental -> experimental-2-link experimental-1-link -> /nix/store/cc4480... experimental-2-link -> /nix/store/a3148f... * `--profile' / `-p' -> `--switch-profile' / `-S' * `--link' / `-l' -> `--profile' / `-p' * The default profile is stored in $prefix/var/nix/profiles. $prefix/var/nix/links is gone. Profiles can be stored anywhere. * The current profile is now referenced from ~/.nix-profile, not ~/.nix-userenv. * The roots to the garbage collector now have extension `.gcroot', not `.id'.
2004-02-04	* Extended the `inherit' syntax to optionally select attributes from	Eelco Dolstra	2	-8/+18
	other attribute sets, rather than the current scope. E.g., {inherit (pkgs) gcc binutils;} is equivalent to {gcc = pkgs.gcc; binutils = pkgs.binutils;} I am not so happy about the syntax.
2004-02-04	* An attribute set update operator (//). E.g.,	Eelco Dolstra	3	-0/+19
	{x=1; y=2; z=3;} // {y=4;} => {x=1; y=4; z=3;}
2004-02-04	* Use a map to lookup primops.	Eelco Dolstra	12	-75/+127
	* Various performance improvements in the evaluator. * Do not link against unused (and missing!) libraries (-lsglr, etc.).
2004-02-03	* Verify that all variables in a Nix expression are defined.	Eelco Dolstra	4	-21/+92

2004-02-02	* Added syntactic sugar to the construction of attribute sets to	Eelco Dolstra	6	-41/+78
	`inherit' variables from the surrounding lexical scope. E.g., {stdenv, libfoo}: derivation { builder = ./bla; inherit stdenv libfoo; xyzzy = 1; } is equivalent to {stdenv, libfoo}: derivation { builder = ./bla; stdenv = stdenv; libfoo = libfoo; xyzzy = 1; } Note that for mutually recursive attribute set definitions (`rec {...}'), this also works, that is, `rec {inherit x;}' is equivalent to `let {fresh = x; body = rec {x = fresh;};}', not `rec {x = x}'.
2004-02-02	* Sort `nix-env -q' output by derivation name.	Eelco Dolstra	4	-11/+28
	* `--version' flag for all commands. * Manual updates.
2004-01-30	* Doh!	Eelco Dolstra	1	-1/+3

2004-01-30	* Parser numbers again.	Eelco Dolstra	3	-2/+6
	* Include missing files in distributions.
2004-01-30	* Detect flex and bison; updated the manual.	Eelco Dolstra	1	-2/+4

2004-01-30	* Replaced the SDF parser by a substantially faster Bison/Flex	Eelco Dolstra	6	-251/+260
	parser (roughly 80x faster). The absolutely latest version of Bison (1.875c) is required for reentrant GLR support, as well as a recent version of Flex (say, 2.5.31). Note that most Unix distributions ship with the prehistoric Flex 2.5.4, which doesn't support reentrancy.
2004-01-29	* Optimised the SDF grammar.	Eelco Dolstra	2	-94/+15

2004-01-21	* Extra bit `S' in `--query --status' output: show whether there are	Eelco Dolstra	1	-1/+3
	any substitutes for the derivation.
2004-01-21	* Fixed a subtle uninitialised variable bug in ATermMaps copied from	Eelco Dolstra	1	-1/+3
	ATermMaps. Found thanks to Valgrind!
2004-01-20	* Absolutise the specified path in `--import' and `--profile'.	Eelco Dolstra	1	-2/+2

2004-01-15	* Remove debug message.	Eelco Dolstra	1	-1/+0

2004-01-15	* Catch SIGINT to terminate cleanly when the user tries to interrupt	Eelco Dolstra	13	-4/+86
	Nix. This is to prevent Berkeley DB from becoming wedged. Unfortunately it is not possible to throw C++ exceptions from a signal handler. In fact, you can't do much of anything except change variables of type `volatile sig_atomic_t'. So we set an interrupt flag in the signal handler and check it at various strategic locations in the code (by calling checkInterrupt()). Since this is unlikely to cover all cases (e.g., (semi-)infinite loops), sometimes SIGTERM may now be required to kill Nix.
2004-01-15	* Obsolete.	Eelco Dolstra	2	-290/+0

2004-01-15	* In `nix-env --query --status', determine the `I' bit by looking at	Eelco Dolstra	1	-1/+7
	the output path of a derivation, not the path of its store expression. This ensures that changes that affect the path of the store expression but not the output path, do not affect the `installed' state of a derivation.
2004-01-13	* Option `-B' to always show the output of builders, regardless of	Eelco Dolstra	4	-1/+9
	verbosity level.
2004-01-13	* Periodically checkpoint the log.	Eelco Dolstra	1	-1/+3

2004-01-13	* Tricky: make sure that the accessor count is not reset to 0 if	Eelco Dolstra	1	-1/+5
	recovery fails.
2004-01-13	* Print error messages, not debug messages.	Eelco Dolstra	1	-5/+9

2004-01-12	* Changed the extension for store expressions from ".nix" to ".store"	Eelco Dolstra	1	-1/+1
	(following the Usenix paper).
2004-01-09	* Option `--force-realise' in `nix-store --query'.	Eelco Dolstra	1	-5/+12

2004-01-07	* Upgraded to Berkeley DB 4.2.52. The main advantage of 4.2 is that	Eelco Dolstra	1	-1/+1
	it automatically removes log files when they are no longer needed. * IMPORTANT * If you have an existing Nix installation, you must checkpoint the Nix database to prevent recent transactions from being undone. Do the following: - optional: make a backup of $prefix/var/nix/db. - run `db_checkpoint' from Berkeley DB 4.1: $ db_checkpoint -h $prefix/var/nix/db -1 - optional (?): run `db_recover' from Berkeley DB 4.1: $ db_recover -h $prefix/var/nix/db - remove $prefix/var/nix/db/log* and $prefix/var/nix/db/__db*
2004-01-05	* Implemented Eelco V.'s `nix-env -I' command to specify the default	Eelco Dolstra	7	-42/+86
	path of the Nix expression to be used with the import, upgrade, and query commands. For instance, $ nix-env -I ~/nixpkgs/pkgs/system/i686-linux.nix $ nix-env --query --available [aka -qa] sylpheed-0.9.7 bison-1.875 pango-1.2.5 subversion-0.35.1 ... $ nix-env -i sylpheed $ nix-env -u subversion There can be only one default at a time. * If the path to a Nix expression is a symlink, follow the symlink prior to resolving relative path references in the expression.
2004-01-05	* Implemented Eelco V.'s `-p' command to switch profiles. It switches	Eelco Dolstra	2	-0/+24
	the symlink ~/.nix-userenv to the given argument (which defaults to .../links/current). /etc/profile.d/nix-profile creates this symlink if it doesn't exist yet. Example use: $ nix-env -l my_profile -i foo.nix subversion quake $ nix-env -p my_profile I don't like the term "profile". Let's deprecate it :-)
2003-12-30	* RPM spec file.	Eelco Dolstra	1	-8/+8
	* Respect DESTDIR variable.
2003-12-23	* Fixed a bug in the upgrade operation.	Eelco Dolstra	1	-11/+13

2003-12-22	* GCC 2.95 compatibility.	Eelco Dolstra	5	-3/+13

2003-12-22	* Upgrade operation in `nix-env'. For instance, you can say	Eelco Dolstra	2	-24/+165
	nix-env -u foo.nix strategoxt to replace the installed `strategoxt' derivation with the one from `foo.nix', if the latter has a higher version number. This is a no-op if `strategoxt' is not installed. Wildcards are also accepted, so nix-env -u foo.nix '' will replace any installed derivation with newer versions from `foo.nix', if available. The notion of "version number" is somewhat ad hoc, but should be useful in most cases, as evidenced by the following unit tests for the version comparator: TEST("1.0", "2.3", -1); TEST("2.1", "2.3", -1); TEST("2.3", "2.3", 0); TEST("2.5", "2.3", 1); TEST("3.1", "2.3", 1); TEST("2.3.1", "2.3", 1); TEST("2.3.1", "2.3a", 1); TEST("2.3pre1", "2.3", -1); TEST("2.3pre3", "2.3pre12", -1); TEST("2.3a", "2.3c", -1); TEST("2.3pre1", "2.3c", -1); TEST("2.3pre1", "2.3q", -1); (-1 = less, 0 = equal, 1 = greater) A new verbosity level `lvlInfo', between `lvlError' and `lvlTalkative'. This is the default for `nix-env', so without any `-v' flags users should get useful output, e.g., $ nix-env -u foo.nix strategoxt upgrading `strategoxt-0.9.2' to `strategoxt-0.9.3'
2003-12-21	* Version numbers can be omitted in install/uninstall. E.g.,	Eelco Dolstra	2	-34/+106
	nix-env -i foo.nix subversion The version number part of a derivation name is defined as everything following the first dash not followed by a letter.
