2012-10-03	Add a ‘--repair’ flag to nix-instantiate	Eelco Dolstra
	This allows repairing corrupted derivations and other source files.
2012-10-03	Handle repairing paths that are in build-chroot-dirs	Eelco Dolstra

2012-10-03	When repairing a derivation, check and repair the entire output closure	Eelco Dolstra
	If we find a corrupted path in the output closure, we rebuild the derivation that produced that particular path.
2012-10-02	Add a --repair flag to ‘nix-store -r’ to repair derivation outputs	Eelco Dolstra
	With this flag, if any valid derivation output is missing or corrupt, it will be recreated by using a substitute if available, or by rebuilding the derivation. The latter may use hash rewriting if chroots are not available.
2012-10-02	nix-store --verify: Add an option ‘--repair’ to repair all ↵	Eelco Dolstra
	missing/corrupt paths Also, return a non-zero exit code if errors remain after verifying/repairing.
2012-10-02	Add operation ‘nix-store --repair-path’	Eelco Dolstra
	This operation allows fixing corrupted or accidentally deleted store paths by redownloading them using substituters, if available. Since the corrupted path cannot be replaced atomically, there is a very small time window (one system call) during which neither the old (corrupted) nor the new (repaired) contents are available. So repairing should be used with some care on critical packages like Glibc.
2012-09-28	Handle octal escapes in /proc/self/mountinfo	Eelco Dolstra

2012-09-28	Print a more descriptive error message if setting up the build environment fails	Eelco Dolstra

2012-09-25	Make the store writable before creating /nix/store/.links	Eelco Dolstra

2012-09-25	Merge branch 'readonly-store'	Eelco Dolstra

2012-09-25	Include <sys/types.h> for off_t	Eelco Dolstra
	Reported by "gio" on IRC.
2012-09-19	Remove setting of the immutable bit	Eelco Dolstra
	Using the immutable bit is problematic, especially in conjunction with store optimisation. For instance, if the garbage collector deletes a file, it has to clear its immutable bit, but if the file has additional hard links, we can't set the bit afterwards because we don't know the remaining paths. So now that we support having the entire Nix store as a read-only mount, we may as well drop the immutable bit. Unfortunately, we have to keep the code to clear the immutable bit for backwards compatibility.
2012-09-19	Support having /nix/store as a read-only bind mount	Eelco Dolstra
	It turns out that the immutable bit doesn't work all that well. A better way is to make the entire Nix store a read-only bind mount, i.e. by doing $ mount --bind /nix/store /nix/store $ mount -o remount,ro,bind /nix/store (This would typically done in an early boot script, before anything from /nix/store is used.) Since Nix needs to be able to write to the Nix store, it now detects if /nix/store is a read-only bind mount and then makes it writable in a private mount namespace.
2012-09-19	Templatise tokenizeString()	Eelco Dolstra

2012-09-18	Keep build directory if not all expected outputs were produced	Eelco Dolstra
	Fixes issue #123 in Nixpkgs.
2012-09-13	RemoteStore::connectToDaemon(): Set close-on-exec flag	Eelco Dolstra
	This ensures that "nix-build --run-env" doesn't keep a connection to the worker open, preventing it from exiting.
2012-09-13	Vacuum the SQLite DB after running the garbage collector	Eelco Dolstra

2012-09-13	Delete paths in a component in topologically sorted order	Eelco Dolstra
	The outputs of a derivation can refer to each other (even though they cannot have cycles), so they have to be deleted in the right order. http://hydra.nixos.org/build/3026118
2012-09-13	Disable auto store optimisation for now	Eelco Dolstra
	I've seen operations like "nix-store --import" take much longer on one system. So default to off until I've investigated this a bit further.
2012-09-13	In startBuilder(), only print the new paths we're building	Eelco Dolstra

2012-09-12	Handle gc-keep-outputs and gc-keep-derivations both enabled	Eelco Dolstra
	If the options gc-keep-outputs and gc-keep-derivations are both enabled, you can get a cycle in the liveness graph. There was a hack to handle this, but it didn't work with multiple-output derivations, causing the garbage collector to fail with errors like ‘error: cannot delete path `...' because it is in use by `...'’. The garbage collector now handles strongly connected components in the liveness graph as a unit and decides whether to delete all or none of the paths in an SCC.
2012-09-12	Build hook: Pass the timeout to the remote builder	Eelco Dolstra
	Note that this will only work if the client has a very recent Nix version (post 15e1b2c223494ecb5efefc3ea0e3b926a6b1d7dc), otherwise the --option flag will just be ignored. Fixes #50.
2012-09-11	Fix "non-zero padding" error	Eelco Dolstra
	Probably it's not a good idea to pass a temporary object to StringSource.
2012-09-11	Support building a derivation if some outputs are already valid (non-chroot ↵	Eelco Dolstra
	case) This uses scary hash rewriting. Fixes #21.
2012-09-11	Remove debug line	Eelco Dolstra

2012-09-11	Support building a derivation if some outputs are already valid	Eelco Dolstra
	This handles the chroot and build hook cases, which are easy. Supporting the non-chroot-build case will require more work (hash rewriting!). Issue #21.
2012-09-11	Include config.h before any other header	Eelco Dolstra
	"config.h" must be included first, because otherwise the compiler might not see the right value of _FILE_OFFSET_BITS. We've had this before; see 705868a8a96a10f70e629433cfffc2d5cd2703eb. In this case, GCC would compute a different address for ‘settings.useSubstitutes’ in misc.cc because of the off_t in ‘settings’.

2012-08-20	In the chroot, make all mounted filesystems private	Eelco Dolstra
	This is required on systemd, which mounts filesystems as "shared" subtrees. Changes to shared trees in a private mount namespace are propagated to the outside world, which is bad.
2012-08-20	Don't bind-mount /proc since we mount our own	Eelco Dolstra

2012-08-19	Fix 1755 permission on temporary directories left behind by ‘-K’	Eelco Dolstra

2012-08-05	Handle amount of disk space saved by hard linking being negative	Eelco Dolstra
	Fixes bogus messages like "currently hard linking saves 17592186044416.00 MiB".
2012-08-05	Fix race condition when two processes create a hard link to a file in .links	Eelco Dolstra
	This is a problem because one process may set the immutable bit before the second process has created its link. Addressed random Hydra failures such as: error: cannot rename `/nix/store/.tmp-link-17397-1804289383' to `/nix/store/rsvzm574rlfip3830ac7kmaa028bzl6h-nixos-0.1pre-git/upstart-interface-version': Operation not permitted

	That is, delete almost nothing (it will still remove unused links from /nix/store/.links).
