2012-11-26	Only substitute wanted outputs of a derivation	Eelco Dolstra	4	-21/+77
	If a derivation has multiple outputs, then we only want to download those outputs that are actuallty needed. So if we do "nix-build -A openssl.man", then only the "man" output should be downloaded. Likewise if another package depends on ${openssl.man}. The tricky part is that different derivations can depend on different outputs of a given derivation, so we may need to restart the corresponding derivation goal if that happens.
2012-11-26	Make "nix-build -A <derivation>.<output>" do the right thing	Eelco Dolstra	8	-14/+82
	For example, given a derivation with outputs "out", "man" and "bin": $ nix-build -A pkg produces ./result pointing to the "out" output; $ nix-build -A pkg.man produces ./result-man pointing to the "man" output; $ nix-build -A pkg.all produces ./result, ./result-man and ./result-bin; $ nix-build -A pkg.all -A pkg2 produces ./result, ./result-man, ./result-bin and ./result-2.
2012-11-20	nix-store -r: Add ‘--ignore-unknown’ flag	Eelco Dolstra	3	-9/+36
	This flag causes paths that do not have a known substitute to be quietly ignored. This is mostly useful for Charon, allowing it to speed up deployment by letting a machine use substitutes for all substitutable paths, instead of uploading them. The latter is frequently faster, e.g. if the target machine has a fast Internet connection while the source machine is on a slow ADSL line.
2012-11-19	nix-store -r: Don't quietly ignore missing paths	Eelco Dolstra	1	-0/+1

2012-11-15	Revert "prim_toPath: Actually make the string a path"	Eelco Dolstra	1	-3/+1
	This reverts commit 2980d1fba97069805c3649c5d99d0356bce6c303. It causes a regression in NixOS evaluation: string `/nix/store/ya3s5gmj3b28170fpbjhgsk8wzymkpa1-pommed-1.39/etc/pommed.conf' cannot refer to other paths
2012-11-15	Disable use of vfork()	Eelco Dolstra	1	-1/+1
	vfork() is just too weird. For instance, in this build: http://hydra.nixos.org/build/3330487 the value fromHook.writeSide becomes corrupted in the parent, even though the child only reads from it. At -O0 the problem goes away. Probably the child is overriding some spilled temporary variable. If I get bored I may implement using posix_spawn() instead.
2012-11-15	Don't use std::cerr in a few places	Eelco Dolstra	5	-30/+34
	Slightly scared of using std::cerr in a vforked process...
2012-11-15	Add some debug code	Eelco Dolstra	1	-1/+1

2012-11-09	Use vfork() instead of fork() if available	Eelco Dolstra	5	-22/+47
	Hopefully this reduces the chance of hitting ‘unable to fork: Cannot allocate memory’ errors. vfork() is used for everything except starting builders.
2012-11-09	Remove definition of non-existant function	Eelco Dolstra	1	-2/+0

2012-11-09	Remove some redundant close() calls	Eelco Dolstra	3	-18/+8
	They are unnecessary because we set the close-on-exec flag.
2012-11-09	Remove the quickExit function	Eelco Dolstra	4	-18/+8

2012-11-09	Remove a Darwin hack that should no longer be needed	Eelco Dolstra	1	-7/+0

2012-11-09	Fix a segfault when auto-calling a "a@{...}" function	Eelco Dolstra	1	-5/+5
	Since the called function can return its argument attribute set (e.g. "a"), the latter should not be allocated on the stack. Reported by Shea.
2012-11-09	Don't start copy-from-other-stores if $NIX_OTHER_STORES is unset	Eelco Dolstra	1	-1/+2
	Slight optimisation.
2012-11-09	Remove unnecessary call to closeMostFDs()	Eelco Dolstra	1	-1/+0
	We have close-on-exec on all FDs now, and there is no security risk in passing open FDs to substituters anyway.
2012-11-06	canonicalizePathMetaData: Fall-back to utimes if lutimes fails due to ENOSYS	Shea Levy	1	-0/+2

2012-10-23	If hashes do not match, print them in base-32 for SHA-1/SHA-256	Eelco Dolstra	3	-1/+10
	Fixes #57.
2012-10-23	prim_toPath: Actually make the string a path	Shea Levy	1	-1/+3

2012-10-11	Shorten the names of temporary build directories	Eelco Dolstra	1	-1/+1

2012-10-04	getDerivation(): Don't always quietly ignore assertion failure	Eelco Dolstra	5	-21/+27
	Ignoring assertion failures makes some sense for nix-env -qa, but not for nix-instantiate/nix-build or hydra-eval-jobs.
2012-10-04	XML writer: flush after newlines	Eelco Dolstra	1	-4/+4
	This is useful for hydra-eval-jobs.
2012-10-04	nix-store --verify: Continue on errors	Eelco Dolstra	1	-2/+4

2012-10-04	Fix regular expression	Eelco Dolstra	1	-1/+1
	http://hydra.nixos.org/build/3123177
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
