2008-01-29	* nix-store --dump-db / --load-db to dump/load the Nix DB.	Eelco Dolstra	1	-31/+3
	* nix-store --register-validity: option to supply the content hash of each path. * Removed compatibility with Nix <= 0.7 stores.
2008-01-15	Fixed exportBuildReferenceGraph	Michael Raskin	1	-12/+59

2007-12-30	Added a way to include derivation with its outputs and dependencies - ↵	Michael Raskin	1	-0/+38
	exportBuildReferenceGraph
2007-11-16	* Flag `--no-build-hook' to disable distributed builds.	Eelco Dolstra	1	-0/+1
	* queryDeriver in daemon mode: don't barf if the other side returns an empty string (which means there is no deriver).
2007-10-29	* On FreeBSD, sys/mount.h needs sys/param.h.	Eelco Dolstra	1	-1/+5

2007-10-27	* Detect whether chroot / bind-mount support is available.	Eelco Dolstra	1	-4/+21

2007-10-27	* Delete the chroot directory automatically.	Eelco Dolstra	1	-14/+34
	* Removed some debug messages.
2007-10-27	* Support for doing builds in a chroot under Linux. The builder is	Eelco Dolstra	1	-4/+134
	executed in a chroot that contains just the Nix store, the temporary build directory, and a configurable set of additional directories (/dev and /proc by default). This allows a bit more purity enforcement: hidden build-time dependencies on directories such as /usr or /nix/var/nix/profiles are no longer possible. As an added benefit, accidental network downloads (cf. NIXPKGS-52) are prevented as well (because files such as /etc/resolv.conf are not available in the chroot). However the usefulness of chroots is diminished by the fact that many builders depend on /bin/sh, so you need /bin in the list of additional directories. (And then on non-NixOS you need /lib as well...)
2007-08-28	* When there are multiple substituters, make sure to release the	Eelco Dolstra	1	-0/+5
	lock on the output path after trying each. Otherwise the pathIsLockedByMe() test gets confused.
2007-08-28	* Fix a race condition with parallel builds where multiple	Eelco Dolstra	1	-10/+86
	fixed-output derivations or substitutions try to build the same store path at the same time. Locking generally catches this, but not between multiple goals in the same process. This happened especially often (actually, only) in the build farm with fetchurl downloads of the same file being executed on multiple machines and then copied back to the main machine where they would clobber each other (NIXBF-13). Solution: if a goal notices that the output path is already locked, then go to sleep until another goal finishes (hopefully the one locking the path) and try again.
2007-08-12	* Get rid of the substitutes database table (NIX-47). Instead, if we	Eelco Dolstra	1	-48/+152
	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).
2007-06-12	* Support queryDeriver() in multi-user installations.	Eelco Dolstra	1	-1/+1

2007-05-01	* Set a terminate() handler to ensure that we leave the BDB	Eelco Dolstra	1	-2/+2
	environment cleanly even when an exception is thrown from a destructor. We still crash, but we don't take all other Nix processes with us.
2007-03-20	* Override the setuid helper using NIX_SETUID_HELPER.	Eelco Dolstra	1	-1/+2

2007-03-19	* Terminate build hooks and substitutes with a TERM signal, not a KILL	Eelco Dolstra	1	-6/+13
	signal. This is necessary because those processes may have joined the BDB environment, so they have to be given a chance to clean up. (NIX-85)
2007-03-07	* Delete the output paths before invoking the build hook.	Eelco Dolstra	1	-14/+14

2007-02-21	* `nix-store --export --sign': sign the Nix archive using the RSA key	Eelco Dolstra	1	-2/+1
	in /nix/etc/nix/signing-key.sec
2007-01-23	* exportReferencesGraph: work on paths within store paths as well.	Eelco Dolstra	1	-2/+10

2006-12-12	* New primop builtins.filterSource, which can be used to filter files	Eelco Dolstra	1	-1/+1
	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.
2006-12-09	* Use deletePathWrapped() in more places.	Eelco Dolstra	1	-8/+22

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	1	-6/+44
	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	* Be less verbose.	Eelco Dolstra	1	-1/+1

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	* If not running as root, let the setuid helper kill the build user's	Eelco Dolstra	1	-27/+36
	processes before and after the build.
2006-12-07	* In the garbage collector, if deleting a path fails, try to fix its	Eelco Dolstra	1	-5/+10
	ownership, then try again.
2006-12-07	* When not running as root, call the setuid helper to change the	Eelco Dolstra	1	-1/+7
	ownership of the build result after the build.
2006-12-07	* Change the ownership of store paths to the Nix account before	Eelco Dolstra	1	-4/+56
	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	1	-21/+37
	builder under the desired build user.
2006-12-07	* Sanity check.	Eelco Dolstra	1	-1/+7

2006-12-07	* Move killUser() to libutil so that the setuid helper can use it.	Eelco Dolstra	1	-48/+27

2006-12-06	* Get rid of `build-users'. We'll just take all the members of	Eelco Dolstra	1	-35/+53
	`build-users-group'. This makes configuration easier: you can just add users in /etc/group.
2006-12-06	* Start of the setuid helper (the program that performs the operations	Eelco Dolstra	1	-3/+4
	that have to be done as root: running builders under different uids, changing ownership of build results, and deleting paths in the store with the wrong ownership).
2006-12-05	* Be less chatty.	Eelco Dolstra	1	-2/+2

2006-12-05	* Urgh. Do setgid() before setuid(), because the semantics of setgid()	Eelco Dolstra	1	-4/+4
	changes completely depending on whether you're root...
2006-12-05	* FreeBSD returns ESRCH when there are no processes to kill.	Eelco Dolstra	1	-4/+8

2006-12-05	* Allow unprivileged users to run the garbage collector and to do	Eelco Dolstra	1	-1/+0
	`nix-store --delete'. But unprivileged users are not allowed to ignore liveness. * `nix-store --delete --ignore-liveness': ignore the runtime roots as well.
2006-12-03	* Removed `build-allow-root'.	Eelco Dolstra	1	-18/+26
	* Added `build-users-group', the group under which builds are to be performed. * Check that /nix/store has 1775 permission and is owner by the build-users-group.
2006-12-03	* Some hackery to propagate the worker's stderr and exceptions to the	Eelco Dolstra	1	-3/+3
	client.
2006-12-02	* Move addTempRoot() to the store API, and add another function	Eelco Dolstra	1	-2/+2
	syncWithGC() to allow clients to register GC roots without needing write access to the global roots directory or the GC lock.
2006-11-30	* More remote operations.	Eelco Dolstra	1	-1/+1
	* Added new operation hasSubstitutes(), which is more efficient than querySubstitutes().size() > 0.
2006-11-30	* Put building in the store API.	Eelco Dolstra	1	-3/+2

2006-11-30	* Refactoring. There is now an abstract interface class StoreAPI	Eelco Dolstra	1	-14/+18
	containing functions that operate on the Nix store. One implementation is LocalStore, which operates on the Nix store directly. The next step, to enable secure multi-user Nix, is to create a different implementation RemoteStore that talks to a privileged daemon process that uses LocalStore to perform the actual operations.
2006-11-13	* Remove the undocumented `noscan' feature. It's no longer necessary	Eelco Dolstra	1	-15/+12
	now that reference scanning is sufficiently streamy.
2006-11-13	* Magic attribute `exportReferencesGraph' that allows the references	Eelco Dolstra	1	-20/+56
	graph to be passed to a builder. This attribute should be a list of pairs [name1 path1 name2 path2 ...]. The references graph of each `pathN' will be stored in a text file `nameN' in the temporary build directory. The text files have the format used by `nix-store --register-validity'. However, the deriver fields are left empty. `exportReferencesGraph' is useful for builders that want to do something with the closure of a store path. Examples: the builders that make initrds and ISO images for NixOS. `exportReferencesGraph' is entirely pure. It's necessary because otherwise the only way for a builder to get this information would be to call `nix-store' directly, which is not allowed (though unfortunately possible).
