2007-02-20	* Start of `nix-store --export' operation for serialising a store	Eelco Dolstra	6	-0/+50
	path. This is like `nix-store --dump', only it also dumps the meta-information of the store path (references, deriver). Will add a `--sign' flag later to add a cryptographic signature, which we will use for exchanging store paths between build farm machines in a secure manner.
2007-02-06	* Fix 64-bit compiler warnings.	Eelco Dolstra	2	-4/+4

2007-02-02	* nix-env now maintains meta info (from the `meta' derivation	Eelco Dolstra	5	-16/+89
	attribute) about installed packages in user environments. Thus, an operation like `nix-env -q --description' shows useful information not only on available packages but also on installed packages. * nix-env now passes the entire manifest as an argument to the Nix expression of the user environment builder (not just a list of paths), so that in particular the user environment builder has access to the meta attributes. * New operation `--set-flag' in nix-env to change meta info of installed packages. This will be useful to pass per-package policies to the user environment builder (e.g., how to resolve collision or whether to disable a package (NIX-80)) or upgrade policies in nix-env (e.g., that a package should be "masked", that is, left untouched by upgrade actions). Example: $ nix-env --set-flag enabled false ghc-6.4
2007-01-29	* Doh!	Eelco Dolstra	1	-2/+0

2007-01-29	* computeStorePathForText: take the references into account when	Eelco Dolstra	5	-6/+18
	computing the store path (NIX-77). This is an important security property in multi-user Nix stores. Note that this changes the store paths of derivations (since the derivation aterms are added using addTextToStore), but not most outputs (unless they use builtins.toFile).
2007-01-29	* Don't capitalise the primop functions.	Eelco Dolstra	1	-76/+81

2007-01-29	* Organise primops.cc a bit better.	Eelco Dolstra	1	-321/+376

2007-01-29	New primitives:	Eelco Dolstra	1	-1/+43
	* `sub' to subtract two numbers. * `stringLength' to get the length of a string. * `substring' to get a substring of a string. These should be enough to allow most string operations to be expressed.
2007-01-29	* filterSource: pass strings to the predicate function instead of	Eelco Dolstra	1	-1/+1
	paths. Paths can have unexpected semantics.
2007-01-24	* Nasty: Glibc clears the TMPDIR environment variable in setuid	Eelco Dolstra	1	-1/+8
	programs, so if a builder uses TMPDIR, then it will fail when executed through nix-setuid-helper. In fact Glibc clears a whole bunch of variables (see sysdeps/generic/unsecvars.h in the Glibc sources), but only TMPDIR should matter in practice. As a workaround, we reinitialise TMPDIR from NIX_BUILD_TOP.
2007-01-23	* exportReferencesGraph: work on paths within store paths as well.	Eelco Dolstra	1	-2/+10

2007-01-15	* Handle multiple indirect symlinks when loading a Nix expression.	Eelco Dolstra	2	-7/+7

2007-01-15	* builtins.filterSource: pass the type of the file ("regular",	Eelco Dolstra	1	-1/+18
	"directory", "symlink") as the second argument to the filter predicate.
2007-01-14	* `nix-store --verify': revive checking the referrers table. This is	Eelco Dolstra	1	-42/+56
	important to get garbage collection to work if there is any inconsistency in the database (because the referrer table is used to determine whether it is safe to delete a path). * `nix-store --verify': show some progress.
2007-01-14	* Make the garbage collector more resilient to certain consistency	Eelco Dolstra	3	-4/+10
	errors: in-use paths now cause a warning, not a fatal error.
2007-01-14	* Option --argstr for passing string arguments easily. (NIX-75)	Eelco Dolstra	6	-27/+63

2007-01-13	* nix-pack-closure: store the top-level store paths in the closure.	Eelco Dolstra	1	-1/+9
	* nix-unpack-closure: extract the top-level paths from the closure and print them on stdout. This allows them to be installed, e.g., "nix-env -i $(nix-unpack-closure)". (NIX-64)
2007-01-13	* Allow multiple --attr / -A arguments in nix-build / nix-instantiate	Eelco Dolstra	1	-15/+20
	(NIX-74).
2007-01-13	* Removed chroot support.	Eelco Dolstra	1	-6/+0

2007-01-13	* Canonicalise ASTs in `nix-instantiate --eval': remove position	Eelco Dolstra	3	-1/+45
	info, sort attribute sets.
2007-01-13	* Memoize strict evaluation.	Eelco Dolstra	2	-13/+29

2007-01-13	* printTermAsXML: treat derivations specially; emit an element	Eelco Dolstra	1	-11/+55
	<derivation outPath=... drvPath=...> attrs </derivation>. Only emit the attributes of any specific derivation only. This prevents exponententially large XML output due to the absense of sharing.
2007-01-13	* Make printing an expression as XML interruptible.	Eelco Dolstra	2	-0/+7

2007-01-13	* Cleanup.	Eelco Dolstra	6	-16/+16

2006-12-13	* Remove debug message.	Eelco Dolstra	1	-1/+0

2006-12-12	* New primop builtins.filterSource, which can be used to filter files	Eelco Dolstra	15	-66/+114
	from a source directory. All files for which a predicate function returns true are copied to the store. Typical example is to leave out the .svn directory: stdenv.mkDerivation { ... src = builtins.filterSource (path: baseNameOf (toString path) != ".svn") ./source-dir; # as opposed to # src = ./source-dir; } This is important because the .svn directory influences the hash in a rather unpredictable and variable way.
2006-12-12	* In dumpPath(): pass a function object that allows files to be	Eelco Dolstra	2	-14/+28
	selectively in/excluded from the dump.
2006-12-12	* New operation `nix-env --set' which sets a user environment to a	Eelco Dolstra	2	-0/+28
	single derivation specified by the argument. This is useful when we want to have a profile for a single derivation, such as a server configuration. Then we can just say (e.g.) $ nix-env -p /.../server-profile -f server.nix --set -A server We can't do queries or upgrades on such a profile, but we can do rollbacks. The advantage over -i is that we don't have to worry about other packages having been installed in the profile previously; --set gets rid of them.
2006-12-12	* New built-in function `builtins.attrNames' that returns the	Eelco Dolstra	1	-0/+21
	names of the attributes in an attribute set.
2006-12-09	* Use lchown() instead of chown() in canonicalisePathMetaData(). This	Eelco Dolstra	1	-8/+38
	matters when running as root, since then we don't use the setuid helper (which already used lchown()). * Also check for an obscure security problem on platforms that don't have lchown. Then we can't change the ownership of symlinks, which doesn't matter except when the containing directory is writable by the owner (which is the case with the top-level Nix store directory).
2006-12-09	* Use deletePathWrapped() in more places.	Eelco Dolstra	3	-22/+31

2006-12-08	* Goal cancellation inside the waitForInput() loop needs to be handled	Eelco Dolstra	1	-38/+85
	very carefully, since it can invalidate iterators into the `children' map.
2006-12-08	* Some refactoring.	Eelco Dolstra	1	-95/+118
	* Throw more exceptions as BuildErrors instead of Errors. This matters when --keep-going is turned on. (A BuildError is caught and terminates the goal in question, an Error terminates the program.)
2006-12-08	* Kill a build if it has gone for more than a certain number of	Eelco Dolstra	4	-20/+79
	seconds without producing output on stdout or stderr (NIX-65). This timeout can be specified using the `--max-silent-time' option or the `build-max-silent-time' configuration setting. The default is infinity (0). * Fix a tricky race condition: if we kill the build user before the child has done its setuid() to the build user uid, then it won't be killed, and we'll potentially lock up in pid.wait(). So also send a conventional kill to the child.
2006-12-08	* Also for convenience, change the ownership of the build output even	Eelco Dolstra	1	-22/+36
	in case of failure.
2006-12-07	* Remove ancient terminology.	Eelco Dolstra	1	-3/+3

2006-12-07	* When keeping the temporary build directory (-K), change the owner	Eelco Dolstra	1	-1/+4
	back to the Nix account.
2006-12-07	* Doh!	Eelco Dolstra	4	-4/+4

2006-12-07	* Be less verbose.	Eelco Dolstra	1	-1/+1

2006-12-07	* Rename all those main.cc files.	Eelco Dolstra	10	-5/+5

2006-12-07	* Check for lchown.	Eelco Dolstra	1	-0/+7

2006-12-07	* Don't count on the Pid deconstructor to kill the child process,	Eelco Dolstra	1	-2/+14
	since if we're running a build user in non-root mode, we can't. Let the setuid helper do it.
2006-12-07	* Move setuidCleanup() to libutil.	Eelco Dolstra	5	-27/+23

2006-12-07	* If not running as root, let the setuid helper kill the build user's	Eelco Dolstra	2	-31/+69
	processes before and after the build.
2006-12-07	* In the garbage collector, if deleting a path fails, try to fix its	Eelco Dolstra	3	-6/+31
	ownership, then try again.
2006-12-07	* When not running as root, call the setuid helper to change the	Eelco Dolstra	2	-7/+13
	ownership of the build result after the build.
2006-12-07	* Change the ownership of store paths to the Nix account before	Eelco Dolstra	3	-38/+104
	deleting them using the setuid helper.
2006-12-07	* Pass the actual build user to the setuid helper.	Eelco Dolstra	1	-22/+10

2006-12-07	* If Nix is not running as root, call the setuid helper to start the	Eelco Dolstra	2	-26/+41
	builder under the desired build user.
2006-12-07	* Sanity check.	Eelco Dolstra	1	-1/+7
