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 -r: Get rid of an unnecessary call to buildPaths/ensurePaths	Eelco Dolstra

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	Print a more descriptive error message if setting up the build environment fails	Eelco Dolstra

2012-09-27	Allow dashes in identifiers	Eelco Dolstra
	In Nixpkgs, the attribute in all-packages.nix corresponding to a package is usually equal to the package name. However, this doesn't work if the package contains a dash, which is fairly common. The convention is to replace the dash with an underscore (e.g. "dbus-lib" becomes "dbus_glib"), but that's annoying. So now dashes are valid in variable / attribute names, allowing you to write: dbus-glib = callPackage ../development/libraries/dbus-glib { }; and buildInputs = [ dbus-glib ]; Since we don't have a negation or subtraction operation in Nix, this is unambiguous.

2012-09-21	Style fix	Eelco Dolstra

2012-09-19	Support xz compression in the download-using-manifests substituter	Eelco Dolstra

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	nix-env --delete-generations: Support --dry-run flag	Eelco Dolstra
	Fixes #43.
2012-09-13	Add a test for nix-profile.sh	Eelco Dolstra

2012-09-13	nix-profile.sh: Revert to single-user version	Eelco Dolstra
	Commit 6a214f3e06fa1c5f0a4d40e555f14d87691af297 copied most of the Nix shell initialisation code from NixOS to nix-profile.sh; however, that code assumes a multi-user install and is Linux-specific (e.g. it calls the "stat" command). So go back to the simple single-user version. Fixes #49.
2012-09-13	Remove double Fedora release suffix	Eelco Dolstra

2012-09-13	Put a time-to-live on negative binary cache lookups	Eelco Dolstra
	Negative lookups are purged from the DB after a day, at most once per day. However, for non-"have" lookups (e.g. all except "nix-env -qas"), negative lookups are ignored after one hour. This is to ensure that you don't have to wait a day for an operation like "nix-env -i" to start using new binaries in the cache. Should probably make this configurable.
2012-09-13	Doh	Eelco Dolstra

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	Fix the store optimisation test	Eelco Dolstra

2012-09-13	Delete manifests in "nix-channel --remove" or when a binary cache is available	Eelco Dolstra

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.
2012-09-12	Fix test failure on Darwin	Eelco Dolstra
	Apparently our DBD::SQLite links against /usr/lib/libsqlite3.dylib, which is an old version that doesn't respect foreign key constraints. So manifests/cache.sqlite doesn't get updated properly when a manifest disappears. We should fix our DBD::SQLite, but in the meantime this will fix the test. http://hydra.nixos.org/build/3017959
2012-09-12	Compatibility fix for WWW::Curl < 4.14	Eelco Dolstra
	Older versions of WWW::Curl don't support scalar references for CURLOPT_WRITEDATA directly. http://hydra.nixos.org/build/3017188
2012-09-11	Don't put results symlinks in the tests directory	Eelco Dolstra

2012-09-11	Test hash rewriting	Eelco Dolstra

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’.
