2013-08-26	Fix typos, especially those that end up in the Nix manual	Ivan Kozik

2013-08-19	Store Nix integers as longs	Eelco Dolstra
	So on 64-bit systems, integers are now 64-bit. Fixes #158.
2013-07-30	killUser: Don't let the child kill itself on Apple	Shea Levy
	The kill(2) in Apple's libc follows POSIX semantics, which means that kill(-1, SIGKILL) will kill the calling process too. Since nix has no way to distinguish between the process successfully killing everything and the process being killed by a rogue builder in that case, it can't safely conclude that killUser was successful. Luckily, the actual kill syscall takes a parameter that determines whether POSIX semantics are followed, so we can call that syscall directly and avoid the issue on Apple.

2013-07-12	Garbage collector: Don't follow symlinks arbitrarily	Eelco Dolstra
	Only indirect roots (symlinks to symlinks to the Nix store) are now supported.
2013-06-20	Don't keep "disabled" substituters running	Eelco Dolstra
	For instance, it's pointless to keep copy-from-other-stores running if there are no other stores, or download-using-manifests if there are no manifests. This also speeds things up because we don't send queries to those substituters.
2013-01-03	Remove tabs	Eelco Dolstra

2013-01-03	Clear any immutable bits in the Nix store	Eelco Dolstra
	Doing this once makes subsequent operations like garbage collecting more efficient since we don't have to call makeMutable() first.
2012-11-26	Make "nix-build -A <derivation>.<output>" do the right thing	Eelco Dolstra
	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.
2012-11-15	Don't use std::cerr in a few places	Eelco Dolstra
	Slightly scared of using std::cerr in a vforked process...
2012-11-15	Add some debug code	Eelco Dolstra

2012-11-09	Use vfork() instead of fork() if available	Eelco Dolstra
	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 some redundant close() calls	Eelco Dolstra
	They are unnecessary because we set the close-on-exec flag.
2012-11-09	Remove the quickExit function	Eelco Dolstra

2012-09-28	Handle octal escapes in /proc/self/mountinfo	Eelco Dolstra

2012-09-19	Templatise tokenizeString()	Eelco Dolstra

2012-08-27	Merge branch 'master' into no-manifests	Eelco Dolstra

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.
2012-08-01	Drop the block count in the garbage collector	Eelco Dolstra

2012-08-01	Doh	Eelco Dolstra

2012-08-01	Report substituter errors to clients of the Nix daemon	Eelco Dolstra

2012-07-26	Set permissions on temporary build directories to 0700	Eelco Dolstra
	Fixes #39.
2012-06-25	When using chroots, use a private PID namespace	Eelco Dolstra
	In a private PID namespace, processes have PIDs that are separate from the rest of the system. The initial child gets PID 1. Processes in the chroot cannot see processes outside of the chroot. This improves isolation between builds. However, processes on the outside can see processes in the chroot and send signals to them (if they have appropriate rights). Since the builder gets PID 1, it serves as the reaper for zombies in the chroot. This might turn out to be a problem. In that case we'll need to have a small PID 1 process that sits in a loop calling wait().
2012-03-05	Set the close-on-exec flag on file descriptors	Eelco Dolstra

2012-02-15	On Linux, make the Nix store really read-only by using the immutable bit	Eelco Dolstra
	I was bitten one time too many by Python modifying the Nix store by creating *.pyc files when run as root. On Linux, we can prevent this by setting the immutable bit on files and directories (as in ‘chattr +i’). This isn't supported by all filesystems, so it's not an error if setting the bit fails. The immutable bit is cleared by the garbage collector before deleting a path. The only tricky aspect is in optimiseStore(), since it's forbidden to create hard links to an immutable file. Thus optimiseStore() temporarily clears the immutable bit before creating the link.
2012-02-09	Use data() instead of c_str() where appropriate	Eelco Dolstra

2011-12-22	* In the garbage collector, delete invalid paths before deleting	Eelco Dolstra
	unreachable paths. This matters when using --max-freed etc.: unreachable paths could become reachable again, so it's nicer to keep them if there is "real" garbage to be deleted. Also, don't use readDirectory() but read the Nix store and delete invalid paths in parallel. This reduces GC latency on very large Nix stores.
2010-12-13	* nix-instantiate: return exit status 100 to denote a permanent build	Eelco Dolstra
	failure. The build hook can use this to distinguish between transient and permanent failures on the remote side.
2010-12-13	* createDirs(path): if path already exists, make sure it's a	Eelco Dolstra
	directory. * Provide a C++ wrapper around lstat().
2010-10-04	* Sync with the trunk.	Eelco Dolstra

2010-10-04	* In printMsg(), ignore failing writes to stderr if we're in an	Eelco Dolstra
	exception handler, otherwise throw an exception. We need to ignore write errors in exception handlers to ensure that cleanup code runs to completion if the other side of stderr has been closed unexpectedly.
2010-08-27	* Experimental feature: allow a derivation to tell the build hook that	Eelco Dolstra
	it requires a certain feature on the build machine, e.g. requiredSystemFeatures = [ "kvm" ]; We need this in Hydra to make sure that builds that require KVM support are forwarded to machines that have KVM support. Probably this should also be enforced for local builds.
2010-08-04	* Sync with the trunk.	Eelco Dolstra

2010-06-24	src/libutil/util.cc: include <limit.h> to ensure that PATH_MAX is defined	Peter Simons

2010-05-12	* Sync with the trunk.	Eelco Dolstra

2010-04-20	* Sync with the trunk.	Eelco Dolstra

2010-04-19	* Don't use the ATerm library for parsing/printing .drv files.	Eelco Dolstra

2010-04-12	* Remove some obsolete functions.	Eelco Dolstra

2010-03-19	* Clean up error messages in killUser().	Eelco Dolstra

2010-02-24	* Don't use fdatasync since it doesn't work on Snow Leopard.	Eelco Dolstra
	* Don't refer to config.h in util.hh, because config.h is not installed (http://hydra.nixos.org/build/303053).
2010-02-24	* Remove the fdatasync check since it's no longer needed.	Eelco Dolstra

2010-02-10	Don't rely on `PATH_MAX' on GNU.	Ludovic Courtès

2010-02-02	* Remove most Cygwin-specific code. Cygwin 1.7 implements advisory	Eelco Dolstra
	POSIX locks, and simulates Unix-style file deletion semantics sufficiently. Note that this means that Nix won't work on Cygwin 1.5 anymore.
2010-01-29	* Added an option "fsync-metadata" to fsync() changes to	Eelco Dolstra
	/nix/var/nix/db. * Removed the function writeStringToFile since it does (almost) the same thing as writeFile.
2009-11-24	* Templatise getIntArg / string2Int.	Eelco Dolstra

2009-11-24	* In the garbage collector, don't count files with a link count > 1 in	Eelco Dolstra
	the "bytes/blocks freed" statistics.
2009-06-30	* Don't show trace information by default (`--show-trace' to enable).	Eelco Dolstra
	NixOS evaluation errors in particular look intimidating and generally aren't very useful. Ideally the builtins.throw messages should be self-contained.
2009-03-28	* Simplify communication with the hook a bit (don't use file	Eelco Dolstra
	descriptors 3/4, just use stdin/stderr).
2008-12-04	* Don't ignore errors from writing to stderr. That way, when	Eelco Dolstra
	nix-store -r (or some other operation) is started via ssh, it will at least have a chance of terminating quickly when the connection is killed. Right now it just runs to completion, because it never notices that stderr is no longer connected to anything. Of course it would be better if sshd would just send a SIGHUP, but it doesn't (https://bugzilla.mindrot.org/show_bug.cgi?id=396).
2008-08-25	* Strip off the `.nix' suffix from the attribute name for files in	Eelco Dolstra
	~/.nix-defexpr, otherwise the attribute cannot be selected with the `-A' option. Useful if you want to stick a Nix expression directly in ~/.nix-defexpr.
2008-08-02	* Make nix-env --dry-run print the paths to be substituted correctly	Eelco Dolstra
	again. (After the previous substituter mechanism refactoring I didn't update the code that obtains the references of substitutable paths.) This required some refactoring: the substituter programs are now kept running and receive/respond to info requests via stdin/stdout.
