2011-07-18	* Support multiple outputs. A derivation can declare multiple outputs	Eelco Dolstra	1	-45/+84
	by setting the ‘outputs’ attribute. For example: stdenv.mkDerivation { name = "aterm-2.5"; src = ...; outputs = [ "out" "tools" "dev" ]; configureFlags = "--bindir=$(tools)/bin --includedir=$(dev)/include"; } This derivation creates three outputs, named like this: /nix/store/gcnqgllbh01p3d448q8q6pzn2nc2gpyl-aterm-2.5 /nix/store/gjf1sgirwfnrlr0bdxyrwzpw2r304j02-aterm-2.5-tools /nix/store/hp6108bqfgxvza25nnxfs7kj88xi2vdx-aterm-2.5-dev That is, the symbolic name of the output is suffixed to the store path (except for the ‘out’ output). Each path is passed to the builder through the corresponding environment variable, e.g., ${tools}. The main reason for multiple outputs is to allow parts of a package to be distributed and garbage-collected separately. For instance, most packages depend on Glibc for its libraries, but don't need its header files. If these are separated into different store paths, then a package that depends on the Glibc libraries only causes the libraries and not the headers to be downloaded. The main problem with multiple outputs is that if one output exists while the others have been garbage-collected (or never downloaded in the first place), and we want to rebuild the other outputs, then this isn't possible because we can't clobber a valid output (it might be in active use). This currently gives an error message like: error: derivation `/nix/store/1s9zw4c8qydpjyrayxamx2z7zzp5pcgh-aterm-2.5.drv' is blocked by its output paths There are two solutions: 1) Do the build in a chroot. Then we don't need to overwrite the existing path. 2) Use hash rewriting (see the ASE-2005 paper). Scary but it should work. This is not finished yet. There is not yet an easy way to refer to non-default outputs in Nix expressions. Also, mutually recursive outputs aren't detected yet and cause the garbage collector to crash.
2011-07-13	* Show the default for --with-store-dir (Nix/211).	Eelco Dolstra	1	-1/+1

2011-07-13	* Allow attribute names to be strings. Based on the	Eelco Dolstra	3	-0/+23
	allow-arbitrary-strinsg-in-names patch by Marc Weber.
2011-07-13	* Fix concurrency issues in download-using-manifests' handling of the	Eelco Dolstra	2	-1/+12
	SQLite manifest cache. The DBI AutoCommit feature caused every process to have an active transaction at all times, which could indefinitely block processes wanting to update the manifest cache. * Disable fsync() in the manifest cache because we don't need integrity (the cache can always be recreated if it gets corrupted).
2011-07-13	* Allow a default value in attribute selection by writing	Eelco Dolstra	9	-22/+70
	x.y.z or default (as originally proposed in https://mail.cs.uu.nl/pipermail/nix-dev/2009-September/002989.html). For instance, an expression like stdenv.lib.attrByPath ["features" "ckSched"] false args can now be written as args.features.ckSched or false
2011-07-06	* Change the right-hand side of the ‘.’ operator from an attribute to	Eelco Dolstra	4	-18/+33
	an attribute path. This is a refactoring to support default values.
2011-07-06	* Test case.	Eelco Dolstra	2	-0/+8

2011-07-06	* In the ‘?’ operator, allow attribute paths. For instance, you can	Eelco Dolstra	4	-24/+47
	write ‘attrs ? a.b’ to test whether ‘attrs’ has an attribute ‘a’ containing an attribute ‘b’. This is more convenient than ‘attrs ? a && attrs.a ? b’. Slight change in the semantics: it's no longer an error if the left-hand side of ‘?’ is not an attribute set. In that case it just returns false. So, ‘null ? foo’ no longer throws an error.

2011-06-30	doc: Fix typo.	Ludovic Courtès	1	-0/+2

2011-05-03	* Use SQLite 3.7.6.2.	Eelco Dolstra	1	-1/+1

2011-04-19	* nix-install-package: unset NIX_REMOTE because $NIX_MANIFESTS_DIR	Eelco Dolstra	1	-1/+4
	doesn't work when building through the Nix daemon. This also ensures an error message when the user doesn't have sufficient privileges to do nix-pull.
2011-04-19	* Handle error messages from the Nix worker containing the `%'	Eelco Dolstra	1	-1/+1
	character. (Nix/216)
2011-04-11	* `nix-env -ub' (`--prebuilt-only') didn't really work because it	Eelco Dolstra	1	-17/+20
	checked too soon whether substitutes are available. That is, it did so for every available package, rather than those matching installed packages. This was very slow and subject to assertion failures. So do the check much later. Idem for `nix-env -qab' and `nix-env -ib'.
2011-04-11	* Read manifests directly into the database, rather than first reading	Eelco Dolstra	1	-60/+65
	them into memory. This brings memory use down to (more or less) O(1). For instance, on my test case, the maximum resident size of download-using-manifests while filling the DB went from 142 MiB to 11 MiB.
2011-04-11	* Lock the database during updates.	Eelco Dolstra	1	-1/+8

2011-04-11	(no commit message)	Eelco Dolstra	1	-0/+6

2011-04-11	* configure: detect whether DBD::SQLite is present. If necessary the	Eelco Dolstra	7	-6/+33
	location to DBI and DBD::SQLite can be passed with --with-dbi and --with-dbd-sqlite.
2011-04-11	* Subtle bug: if you import File::stat in one module, it affects other	Eelco Dolstra	2	-5/+7
	modules as well. So use symbolic field names everywhere (which is nicer anyway).
2011-04-11	* Create $manifestDir if it doesn't exist.	Eelco Dolstra	1	-0/+3

2011-04-10	* Cache the manifests in /nix/var/nix/manifests in a SQLite database.	Eelco Dolstra	2	-30/+164
	This significantly speeds up the download-using-manifests substituter, especially if manifests are very large. For instance, one "nix-build -A geeqie" operation that updated four packages using binary patches went from 18.5s to 1.6s. It also significantly reduces memory use. The cache is kept in /nix/var/nix/manifests/cache.sqlite. It's updated automatically when manifests are added to or removed from /nix/var/nix/manifests. It might be interesting to have nix-pull store manifests directly in the DB, rather than storing them as separate flat files, but then we would need a command line interface to delete manifests from the DB.
2011-04-06	* Remove the localPaths feature in manifests since it's no longer used	Eelco Dolstra	7	-47/+10
	and redundant anyway.
2011-03-16	* Print a better error message.	Eelco Dolstra	1	-1/+1

2011-03-15	* Fix a bug in the documentation (reported by Olexiy Buyanskyy,	Eelco Dolstra	1	-1/+1
	Nix/215).
2011-02-17	(no commit message)	Eelco Dolstra	1	-1/+1

2011-02-17	* nix-push: handle the case where the hash is not set in the DB.	Eelco Dolstra	1	-0/+10

2011-02-14	* Build for Ubuntu 10.04.	Eelco Dolstra	1	-0/+2

2011-02-14	make nix-mode provide 'nix-mode	Florian Friesdorf	1	-0/+2
	this enables (require 'nix-mode)
2011-02-10	* Don't allocate a big initial GC address space on machines with	Eelco Dolstra	2	-12/+25
	little RAM. Even if the memory isn't actually used, it can cause problems with the overcommit heuristics in the kernel. So use a VM space of 25% of RAM, up to 384 MB.
2011-02-09	* Don't call GC_expand_hp unless we're actually using the garbage	Eelco Dolstra	2	-12/+18
	collector.
2011-02-09	Use $BDW_GC_LIBS instead of a custom variable.	Ludovic Courtès	3	-4/+2

2011-02-09	* A better fix. $boehmgc isn't set anywhere, we should use the flags	Eelco Dolstra	2	-2/+2
	returned by pkg-config.
2011-02-09	* The GC library can't be found on Solaris	Eelco Dolstra	1	-1/+1
	(http://hydra.nixos.org/build/890714), so don't build with GC support for now.
2011-02-09	* Urgh, FreeBSD doesn't have a "seq" command.	Eelco Dolstra	1	-2/+2

2011-02-09	* Obsolete.	Eelco Dolstra	22	-353/+0

2011-02-05	* Clang compatibility fix. Clang actually checks template definitions	Eelco Dolstra	1	-1/+1

2011-01-14	Remove useless <config.h> inclusion from public header.	Ludovic Courtès	1	-2/+0

2011-01-14	* builtins.substring: if "start" is beyond the end of the string,	Eelco Dolstra	3	-2/+4
	return the empty string.
2010-12-22	* In Hydra manifests the Size field is missing, so don't rely on it.	Eelco Dolstra	1	-2/+2
	This caused a lot of "Use of uninitialized value" warnings from Perl.
2010-12-17	* Do a short sleep after SQLITE_BUSY.	Eelco Dolstra	2	-2/+12

2010-12-17	* Propagate the "100" exit status for failed builds through the Nix	Eelco Dolstra	3	-5/+9
