2014-07-24	Use pthread_cancel instead of a signal	Eelco Dolstra	1	-5/+2
	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	Add some assertions	Eelco Dolstra	1	-0/+6

2014-07-23	nix-daemon: Simplify stderr handling	Eelco Dolstra	1	-0/+1

2014-07-23	nix-daemon: Use a thread instead of SIGPOLL to catch client disconnects	Eelco Dolstra	1	-0/+43
	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.

2014-07-18	Better fix for strcasecmp on Darwin	Eelco Dolstra	1	-3/+1

2014-07-17	Ugly hack to fix building on old Darwin	Eelco Dolstra	1	-0/+3

2014-07-16	Get rid of a compiler warning	Eelco Dolstra	1	-1/+2

2014-07-16	Be more strict about file names in NARs	Eelco Dolstra	1	-1/+6

2014-07-16	Handle case collisions on case-insensitive systems	Eelco Dolstra	2	-75/+100
	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.
2014-07-10	Fix broken Pid constructor	Eelco Dolstra	1	-5/+2

2014-07-10	Refactoring: Move all fork handling into a higher-order function	Eelco Dolstra	2	-54/+60
	C++11 lambdas ftw.
2014-07-10	Remove maybeVfork	Eelco Dolstra	2	-11/+1

2014-07-09	Fix compilation error on some versions of GCC	Eelco Dolstra	1	-2/+2
	src/libexpr/primops.cc:42:8: error: looser throw specifier for 'virtual nix::InvalidPathError::~InvalidPathError()' src/libexpr/nixexpr.hh:12:1: error: overriding 'virtual nix::EvalError::~EvalError() noexcept (true)' http://hydra.nixos.org/build/12385750
2014-06-12	Don't use member initialisers	Eelco Dolstra	1	-4/+4
	They're a little bit too recent (only supported since GCC 4.7). http://hydra.nixos.org/build/11851475
2014-06-12	Fix bogus warnings about dumping large paths	Eelco Dolstra	1	-2/+2
	Also, yay for C++11 non-static initialisers.
2014-06-10	Print a warning when loading a large path into memory	Eelco Dolstra	2	-4/+30
	I.e. if you have a derivation with src = ./huge-directory; you'll get a warning that this is not a good idea.
2014-05-21	nix-store -l: Fetch build logs from the Internet	Eelco Dolstra	2	-1/+3
	If a build log is not available locally, then ‘nix-store -l’ will now try to download it from the servers listed in the ‘log-servers’ option in nix.conf. For instance, if you have: log-servers = http://hydra.nixos.org/log then it will try to get logs from http://hydra.nixos.org/log/<base name of the store path>. So you can do things like: $ nix-store -l $(which xterm) and get a log even if xterm wasn't built locally.
2014-04-08	If a .drv cannot be parsed, show its path	Eelco Dolstra	2	-1/+3
	Otherwise you just get ‘expected string `Derive(['’ which isn't very helpful.
2014-04-03	Tweak error message	Eelco Dolstra	1	-1/+1

2014-03-28	Don't interpret strings as format strings	Eelco Dolstra	3	-23/+32
	Ludo reported this error: unexpected Nix daemon error: boost::too_few_args: format-string refered to more arguments than were passed coming from this line: printMsg(lvlError, run.program + ": " + string(err, 0, p)); The problem here is that the string ends up implicitly converted to a Boost format() object, so % characters are treated specially. I always assumed (wrongly) that strings are converted to a format object that outputs the string as-is. Since this assumption appears in several places that may be hard to grep for, I've added some C++ type hackery to ensures that the right thing happens. So you don't have to worry about % in statements like printMsg(lvlError, "foo: " + s); or throw Error("foo: " + s);
2014-03-12	Remove unnecessary null pointer checks	Eelco Dolstra	1	-2/+2
	Fixes #225.
2014-02-27	Set up a minimal /dev in chroots	Eelco Dolstra	3	-2/+11
	Not bind-mounting the /dev from the host also solves the problem with /dev/shm being a symlink to something not in the chroot.

2014-01-09	Update Makefiles	Eelco Dolstra	1	-2/+2

2013-11-25	Rename Makefile.new -> Makefile	Eelco Dolstra	1	-0/+0

2013-11-23	Use libnix as a prefix for all Nix libraries	Eelco Dolstra	1	-0/+2
	In particular "libutil" was always a problem because it collides with Glibc's libutil. Even if we install into $(libdir)/nix, the linker sometimes got confused (e.g. if a program links against libstore but not libutil, then ld would report undefined symbols in libstore because it was looking at Glibc's libutil).
2013-11-23	Allow (dynamic) libraries to depend on other libraries	Eelco Dolstra	1	-1/+1

2013-11-22	Support building dynamic libraries	Eelco Dolstra	1	-2/+2

2013-11-22	Drop the dependency on Automake	Eelco Dolstra	1	-1/+3

2013-11-22	Rename $(here) to $(d) for brevity, and remove trailing slash	Eelco Dolstra	1	-4/+5

2013-11-22	New non-recursive, plain Make-based build system	Eelco Dolstra	1	-0/+10

2013-11-14	Remove nix-setuid-helper	Eelco Dolstra	2	-17/+0
	AFAIK, nobody uses it, it's not maintained, and it has no tests.
2013-09-17	RestoreSink: Slightly reduce the number of concurrent FDs	Eelco Dolstra	1	-0/+1

2013-09-06	Don't apply the CPU affinity hack to nix-shell (and other Perl programs)	Eelco Dolstra	1	-6/+5
	As discovered by Todd Veldhuizen, the shell started by nix-shell has its affinity set to a single CPU. This is because nix-shell connects to the Nix daemon, which causes the affinity hack to be applied. So we turn this off for Perl programs.
2013-08-26	Fix typos, especially those that end up in the Nix manual	Ivan Kozik	2	-3/+3

2013-08-19	Store Nix integers as longs	Eelco Dolstra	2	-9/+6
	So on 64-bit systems, integers are now 64-bit. Fixes #158.
2013-08-07	Fix build on non-Linux	Eelco Dolstra	1	-0/+2
	http://hydra.nixos.org/build/5662914
2013-08-07	Run the daemon worker on the same CPU as the client	Eelco Dolstra	3	-2/+65
	On a system with multiple CPUs, running Nix operations through the daemon is significantly slower than "direct" mode: $ NIX_REMOTE= nix-instantiate '<nixos>' -A system real 0m0.974s user 0m0.875s sys 0m0.088s $ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system real 0m2.118s user 0m1.463s sys 0m0.218s The main reason seems to be that the client and the worker get moved to a different CPU after every call to the worker. This patch adds a hack to lock them to the same CPU. With this, the overhead of going through the daemon is very small: $ NIX_REMOTE=daemon nix-instantiate '<nixos>' -A system real 0m1.074s user 0m0.809s sys 0m0.098s
2013-07-30	killUser: Don't let the child kill itself on Apple	Shea Levy	1	-0/+13
	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	2	-0/+13
	Only indirect roots (symlinks to symlinks to the Nix store) are now supported.
2013-06-20	Don't keep "disabled" substituters running	Eelco Dolstra	1	-0/+1
	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.
2013-06-07	Process stderr from substituters while doing have/info queries	Eelco Dolstra	2	-0/+8
