2012-10-03	Rename nix-worker to nix-daemon	Eelco Dolstra	4	-16/+19

2012-10-03	Drop support for running nix-worker in "slave" mode	Eelco Dolstra	4	-136/+7
	AFAIK nobody uses this, setuid binaries are evil, and there is no good reason why people can't just run the daemon.
2012-10-03	Remove bin2c	Eelco Dolstra	5	-31/+4

2012-10-03	When ‘--help’ is given, just run ‘man’ to show the manual page	Eelco Dolstra	17	-240/+23
	I.e. do what git does. I'm too lazy to keep the builtin help text up to date :-) Also add ‘--help’ to various commands that lacked it (e.g. nix-collect-garbage).
2012-10-03	nix-env: Support ‘--repair’ flag	Eelco Dolstra	3	-5/+9

2012-10-03	Add a ‘--repair’ flag to nix-instantiate	Eelco Dolstra	11	-25/+36
	This allows repairing corrupted derivations and other source files.
2012-10-03	Handle repairing paths that are in build-chroot-dirs	Eelco Dolstra	1	-0/+7

2012-10-03	When repairing a derivation, check and repair the entire output closure	Eelco Dolstra	3	-6/+91
	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	7	-64/+116
	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	1	-4/+4

2012-10-02	nix-store --verify: Add an option ‘--repair’ to repair all ↵	Eelco Dolstra	3	-10/+30
	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	3	-28/+88
	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	3	-2/+24

2012-09-28	Print a more descriptive error message if setting up the build environment fails	Eelco Dolstra	1	-3/+14

2012-09-27	Allow dashes in identifiers	Eelco Dolstra	1	-1/+1
	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.
2012-09-25	Make the store writable before creating /nix/store/.links	Eelco Dolstra	1	-2/+1

2012-09-25	Merge branch 'readonly-store'	Eelco Dolstra	14	-135/+106

2012-09-25	Include <sys/types.h> for off_t	Eelco Dolstra	1	-0/+1
	Reported by "gio" on IRC.
2012-09-19	Remove setting of the immutable bit	Eelco Dolstra	5	-96/+35
	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	2	-0/+41
	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	10	-39/+30

2012-09-18	Keep build directory if not all expected outputs were produced	Eelco Dolstra	1	-3/+3
	Fixes issue #123 in Nixpkgs.
2012-09-13	nix-env --delete-generations: Support --dry-run flag	Eelco Dolstra	1	-5/+10
	Fixes #43.
2012-09-13	RemoteStore::connectToDaemon(): Set close-on-exec flag	Eelco Dolstra	1	-0/+1
	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	3	-0/+12

2012-09-13	Delete paths in a component in topologically sorted order	Eelco Dolstra	1	-1/+3
	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	1	-1/+1
	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	1	-2/+3

2012-09-12	Handle gc-keep-outputs and gc-keep-derivations both enabled	Eelco Dolstra	1	-94/+97
	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	1	-1/+1
	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	1	-1/+2
	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	1	-11/+67
	case) This uses scary hash rewriting. Fixes #21.
2012-09-11	Remove debug line	Eelco Dolstra	1	-3/+1

2012-09-11	Support building a derivation if some outputs are already valid	Eelco Dolstra	1	-12/+16
	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	2	-2/+4
	"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’.

2012-08-27	Merge branch 'master' into no-manifests	Eelco Dolstra	19	-133/+319

2012-08-24	Include the output name in the GC root link	Eelco Dolstra	4	-17/+12
	Output names are now appended to resulting GC symlinks, e.g. by nix-build. For backwards compatibility, if the output is named "out", nothing is appended. E.g. doing "nix-build -A foo" on a derivation that produces outputs "out", "bin" and "dev" will produce symlinks "./result", "./result-bin" and "./result-dev", respectively.
2012-08-22	Receive reserveSpace before calling startWork()	Eelco Dolstra	1	-4/+4
	Otherwise we can get a SIGPOLL. Reported by Ludovic.
2012-08-20	Check if MS_PRIVATE is defined	Eelco Dolstra	1	-1/+1

2012-08-20	In the chroot, make all mounted filesystems private	Eelco Dolstra	3	-3/+21
	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	1	-2/+2

2012-08-19	Fix 1755 permission on temporary directories left behind by ‘-K’	Eelco Dolstra	1	-4/+4

2012-08-13	Avoid concatenating lists of one string	Eelco Dolstra	2	-2/+2

2012-08-13	Don't allocate empty lists	Eelco Dolstra	1	-1/+1
	This saves about 4 MB when evaluating a NixOS system configuration.
2012-08-13	Optimise concatenating a list to an empty list	Eelco Dolstra	1	-2/+10
	More precisely, in concatLists, if all lists except one are empty, then just return the non-empty list. This reduces the number of list element allocations by 32% when evaluating a NixOS system configuration.
