2014-08-04	Add option ‘build-extra-chroot-dirs’	Eelco Dolstra
	This is useful for extending (rather than overriding) the default set of chroot paths.
2014-08-04	Get rid of "killing <pid>" message for unused build hooks	Eelco Dolstra

2014-08-04	Make chroot builds easier to set up	Eelco Dolstra
	By default, we now include /bin/sh as a bind-mount of bash.
2014-08-01	Remove ugly hack for detecting build environment setup errors	Eelco Dolstra

2014-08-01	Call commonChildInit() before doing chroot init	Eelco Dolstra
	This ensures that daemon clients see error messages from the chroot setup.
2014-08-01	Eliminate redundant copy	Eelco Dolstra

2014-08-01	findRoots(): Prevent a call to lstat()	Eelco Dolstra
	This means that getting the roots from /nix/var/nix/.../hydra-roots doesn't need any I/O other than reading the directory.
2014-08-01	Make readDirectory() return inode / file type	Eelco Dolstra

2014-08-01	Allow regular files as GC roots	Eelco Dolstra
	If a root is a regular file, then its name must denote a store path. For instance, the existence of the file /nix/var/nix/gcroots/per-user/eelco/hydra-roots/wzc3cy1wwwd6d0dgxpa77ijr1yp50s6v-libxml2-2.7.7 would cause /nix/store/wzc3cy1wwwd6d0dgxpa77ijr1yp50s6v-libxml2-2.7.7 to be a root. This is useful because it involves less I/O (no need for a readlink() call) and takes up less disk space (the symlink target typically takes up a full disk block, while directory entries are packed more efficiently). This is particularly important for hydra.nixos.org, which has hundreds of thousands of roots, and where reading the roots can take 25 minutes.
2014-07-31	Restore default SIGPIPE handler before invoking ‘man’	Eelco Dolstra
	Fixes NixOS/nixpkgs#3410.
2014-07-30	Rename nixPath to __nixPath	Eelco Dolstra
	The name ‘nixPath’ breaks existing code.
2014-07-25	nix-daemon: Pass on the user's $SSH_AUTH_SOCK to the SSH substituter	Eelco Dolstra

2014-07-25	Change the default for use-ssh-substituter to ‘true’	Eelco Dolstra
	Now you only have to pass ‘--option ssh-substituter-hosts nix-ssh@bla’ to enable SSH substitution.
2014-07-24	nix-copy-closure: Drop --bzip2, --xz, --show-progress	Eelco Dolstra
	These are too difficult to implement via nix-store --serve. ‘--show-progress’ could be re-implemented fairly easily via a sink/source wrapper class.
2014-07-24	Implement nix-copy-closure --from via nix-store --serve	Eelco Dolstra

2014-07-24	build-remote.pl: Be less verbose on failing builds	Eelco Dolstra

2014-07-24	nix-store --serve: Only monitor stdin during builds	Eelco Dolstra
	Other operations cannot hang indefinitely (except when we're reading from stdin, in which case we'll notice a client disconnect). But monitoring works badly during compressed imports, since there the client can close the connection before we've sent an ack. http://hydra.nixos.org/build/12711638
2014-07-24	Use pthread_cancel instead of a signal	Eelco Dolstra
	Signal handlers are process-wide, so sending SIGINT to the monitor thread will cause the normal SIGINT handler to run. This sets the isInterrupted flag, which is not what we want. So use pthread_cancel instead.
2014-07-24	Fix bogus pass by reference	Eelco Dolstra
	http://hydra.nixos.org/build/12711659
2014-07-24	More debugging	Eelco Dolstra

2014-07-24	Add some assertions	Eelco Dolstra

2014-07-24	Remove some dead code	Eelco Dolstra

2014-07-23	Remove some obsolete files	Eelco Dolstra

2014-07-23	Pass -pthread only for programs that need it	Eelco Dolstra

2014-07-23	nix-daemon: Less verbosity	Eelco Dolstra

2014-07-23	nix-daemon: Simplify stderr handling	Eelco Dolstra

2014-07-23	nix-store --serve: Monitor for client disconnects	Eelco Dolstra
	This is necessary because build-remote.pl now builds via ‘nix-store --serve’. So if a build hangs without writing to stdout/stderr, and the client disconnects, then we need to detect that.
2014-07-23	nix-daemon: Use a thread instead of SIGPOLL to catch client disconnects	Eelco Dolstra
	The thread calls poll() to wait until a HUP (or other error event) happens on the client connection. If so, it sends SIGINT to the main thread, which is then cleaned up normally. This is much nicer than messing around with SIGPOLL.
2014-07-23	startProcess: Make writing error messages from the child more robust	Eelco Dolstra

2014-07-23	Remove dead code	Eelco Dolstra

2014-07-19	Revert old useBuildHook behaviour	Eelco Dolstra

2014-07-18	Better fix for strcasecmp on Darwin	Eelco Dolstra

2014-07-17	Ugly hack to fix building on old Darwin	Eelco Dolstra
	http://hydra.nixos.org/build/12580878
2014-07-17	nix-daemon: Add trusted-users and allowed-users options	Eelco Dolstra
	‘trusted-users’ is a list of users and groups that have elevated rights, such as the ability to specify binary caches. It defaults to ‘root’. A typical value would be ‘@wheel’ to specify all users in the wheel group. ‘allowed-users’ is a list of users and groups that are allowed to connect to the daemon. It defaults to ‘*’. A typical value would be ‘@users’ to specify the ‘users’ group.
2014-07-17	nix-daemon: Show name of connecting user	Eelco Dolstra

2014-07-17	nix-daemon: Only print connection info if we have SO_PEERCRED	Eelco Dolstra

2014-07-17	nix-daemon: Fix compat with older clients	Eelco Dolstra

2014-07-16	Get rid of a compiler warning	Eelco Dolstra

2014-07-16	Be more strict about file names in NARs	Eelco Dolstra

2014-07-16	Handle case collisions on case-insensitive systems	Eelco Dolstra
	When running NixOps under Mac OS X, we need to be able to import store paths built on Linux into the local Nix store. However, HFS+ is usually case-insensitive, so if there are directories with file names that differ only in case, then importing will fail. The solution is to add a suffix ("~nix~case~hack~<integer>") to colliding files. For instance, if we have a directory containing xt_CONNMARK.h and xt_connmark.h, then the latter will be renamed to "xt_connmark.h~nix~case~hack~1". If a store path is dumped as a NAR, the suffixes are removed. Thus, importing and exporting via a case-insensitive Nix store is round-tripping. So when NixOps calls nix-copy-closure to copy the path to a Linux machine, you get the original file names back. Closes #119.
2014-07-14	build-remote.pl: Fix building multiple output derivations	Eelco Dolstra
	We were importing paths without sorting them topologically, leading to "path is not valid" errors. See e.g. http://hydra.nixos.org/build/12451761
2014-07-11	build-remote.pl: Use ‘nix-store --serve’ on the remote side	Eelco Dolstra
	This makes things more efficient (we don't need to use an SSH master connection, and we only start a single remote process) and gets rid of locking issues (the remote nix-store process will keep inputs and outputs locked as long as they're needed). It also makes it more or less secure to connect directly to the root account on the build machine, using a forced command (e.g. ‘command="nix-store --serve --write"’). This bypasses the Nix daemon and is therefore more efficient. Also, don't call nix-store to import the output paths.
2014-07-11	Allow $NIX_BUILD_HOOK to be relative to Nix libexec directory	Eelco Dolstra

2014-07-10	Fix broken Pid constructor	Eelco Dolstra

2014-07-10	Replace message "importing path <...>" with "exporting path <...>"	Eelco Dolstra
	This causes nix-copy-closure to show what it's doing before rather than after.
2014-07-10	nix-copy-closure -s: Do substitutions via ‘nix-store --serve’	Eelco Dolstra
	This means we no longer need an SSH master connection, since we only execute a single command on the remote host.
2014-07-10	Remove tabs	Eelco Dolstra

2014-07-10	Refactoring: Move all fork handling into a higher-order function	Eelco Dolstra
	C++11 lambdas ftw.
