2014-07-24	build-remote.pl: Be less verbose on failing builds	Eelco Dolstra	1	-4/+4

2014-07-24	nix-store --serve: Only monitor stdin during builds	Eelco Dolstra	1	-2/+2
	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	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.

2014-07-23	nix-daemon: Simplify stderr handling	Eelco Dolstra	2	-7/+2

2014-07-23	nix-store --serve: Monitor for client disconnects	Eelco Dolstra	1	-0/+3
	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	2	-146/+50
	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
	http://hydra.nixos.org/build/12580878
2014-07-17	nix-daemon: Add trusted-users and allowed-users options	Eelco Dolstra	3	-3/+48
	‘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	1	-6/+7

2014-07-17	nix-daemon: Only print connection info if we have SO_PEERCRED	Eelco Dolstra	1	-9/+12

2014-07-17	nix-daemon: Fix compat with older clients	Eelco Dolstra	1	-1/+1

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	3	-75/+102
	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	2	-2/+3
	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	3	-5/+35
	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	2	-3/+5

2014-07-10	Fix broken Pid constructor	Eelco Dolstra	1	-5/+2

2014-07-10	Replace message "importing path <...>" with "exporting path <...>"	Eelco Dolstra	1	-2/+2
	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	2	-0/+30
	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	1	-3/+3

2014-07-10	Refactoring: Move all fork handling into a higher-order function	Eelco Dolstra	7	-206/+128
	C++11 lambdas ftw.
2014-07-10	nix-copy-closure: Restore compression and the progress viewer	Eelco Dolstra	1	-2/+47

2014-07-10	Remove maybeVfork	Eelco Dolstra	4	-14/+4

2014-07-10	nix-copy-closure: Fix race condition	Eelco Dolstra	3	-57/+62
	There is a long-standing race condition when copying a closure to a remote machine, particularly affecting build-remote.pl: the client first asks the remote machine which paths it already has, then copies over the missing paths. If the garbage collector kicks in on the remote machine between the first and second step, the already-present paths may be deleted. The missing paths may then refer to deleted paths, causing nix-copy-closure to fail. The client now performs both steps using a single remote Nix call (using ‘nix-store --serve’), locking all paths in the closure while querying. I changed the --serve protocol a bit (getting rid of QueryCommand), so this breaks the SSH substituter from older versions. But it was marked experimental anyway. Fixes #141.
2014-07-10	Fix security hole in ‘nix-store --serve’	Eelco Dolstra	1	-1/+1
	Since it didn't check that the path received from the client is a store path, the client could dump any path in the file system.
2014-07-09	Fix compilation error on some versions of GCC	Eelco Dolstra	2	-2/+3
	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
2014-07-04	Add builtin function ‘fromJSON’	Eelco Dolstra	3	-0/+167
	Fixes #294.

2014-06-27	Add `--json` argument to `nix-instantiate`	Paul Colomiets	1	-6/+17

2014-06-27	allow-arbitrary-code-during-evaluation -> ↵	Eelco Dolstra	1	-1/+1
	allow-unsafe-native-code-during-evaluation
2014-06-24	Only add the importNative primop if the ↵	Shea Levy	3	-1/+7
	allow-arbitrary-code-during-evaluation option is true (default false)
2014-06-17	Add importNative primop	Shea Levy	2	-0/+44
	This can be used to import a dynamic shared object and return an arbitrary value, including new primops. This can be used both to test new primops without having to recompile nix every time, and to build specialized primops that probably don't belong upstream (e.g. a function that calls out to gpg to decrypt a nixops secret as-needed). The imported function should initialize the Value & as needed. A single import can define multiple values by creating an attrset or list, of course. An example initialization function might look like: extern "C" void initialize(nix::EvalState & state, nix::Value & v) { v.type = nix::tPrimOp; v.primOp = NEW nix::PrimOp(myFun, 1, state.symbols.create("myFun")); } Then `builtins.importNative ./example.so "initialize"` will evaluate to the primop defined in the myFun function.
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.
2014-06-12	Drop ImportError and FindError	Eelco Dolstra	2	-6/+0
	We're not catching these anywhere.
2014-06-12	findFile: Realise the context of the path attributes	Shea Levy	2	-18/+45

2014-06-12	Share code between scopedImport and import	Shea Levy	1	-42/+44
	In addition to reducing duplication, this fixes both import from derivation and import of derivation for scopedImport
2014-06-10	== operator: Ignore string context	Eelco Dolstra	2	-12/+3
	There really is no case I can think of where taking the context into account is useful. Mostly it's just very inconvenient.
