2013-06-20	Don't set $preferLocalBuild and $requiredSystemFeatures in builders	Eelco Dolstra	2	-8/+15
	With C++ std::map, doing a comparison like ‘map["foo"] == ...’ has the side-effect of adding a mapping from "foo" to the empty string if "foo" doesn't exist in the map. So we ended up setting some environment variables by accident.
2013-06-20	Don't substitute derivations that have preferLocalBuild set	Eelco Dolstra	3	-7/+15
	In particular this means that "trivial" derivations such as writeText are not substituted, reducing the number of GET requests to the binary cache by about 200 on a typical NixOS configuration.
2013-06-20	Increase SQLite's auto-checkpoint interval	Eelco Dolstra	1	-2/+2
	Common operations like instantiating a NixOS system config no longer fitted in 8192 pages, leading to more fsyncs. So increase this limit.
2013-06-20	Disable the copy-from-other-stores substituter	Eelco Dolstra	1	-0/+2
	This substituter basically cannot work reliably since we switched to SQLite, since SQLite databases may need write access to open them even just for reading (and in WAL mode they always do).
2013-06-20	Don't keep "disabled" substituters running	Eelco Dolstra	9	-7/+46
	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.
2013-06-17	Bump version	Eelco Dolstra	1	-1/+1

2013-06-17	Update release notes for Nix 1.5.3	Eelco Dolstra	1	-0/+48

2013-06-13	Allow hard links between the outputs of a derivation	Eelco Dolstra	3	-9/+20

2013-06-13	Fix a security bug in hash rewriting	Eelco Dolstra	1	-0/+6
	Before calling dumpPath(), we have to make sure the files are owned by the build user. Otherwise, the build could contain a hard link to (say) /etc/shadow, which would then be read by the daemon and rewritten as a world-readable file. This only affects systems that don't have hard link restrictions enabled.
2013-06-13	Fix assertion failure in canonicalisePathMetaData() after hash rewriting	Eelco Dolstra	1	-2/+9
	The assertion in canonicalisePathMetaData() failed because the ownership of the path already changed due to the hash rewriting. The solution is not to check the ownership of rewritten paths. Issue #122.
2013-06-13	computeFSClosure: Only process the missing/corrupt paths	Eelco Dolstra	1	-11/+17
	Issue #122.
2013-06-13	Typo	Eelco Dolstra	1	-1/+1

2013-06-13	In repair mode, update the hash of rebuilt paths	Eelco Dolstra	2	-4/+5
	Otherwise subsequent invocations of "--repair" will keep rebuilding the path. This only happens if the path content differs between builds (e.g. due to timestamps).
2013-06-12	nix-daemon: Trust options like binary-caches when the client is root	Eelco Dolstra	1	-5/+7
	Fixes #127.
2013-06-07	download-from-binary-cache.pl: Respect $NIX_CONNECT_TIMEOUT	Eelco Dolstra	1	-0/+1

2013-06-07	Replace $NIX_DEBUG_SUBST with an option ‘debug-subst’	Eelco Dolstra	1	-1/+1
	Thus passing ‘--option debug-subst 1’ allows daemon users to turn on debug info and see what the substituter is doing.
2013-06-07	download-from-binary-cache.pl: Show if we're waiting for a URL	Eelco Dolstra	1	-3/+15
	Previously, if a binary cache is hanging/unreachable/slow, download-from-binary-cache.pl would also hang without any indication to the user. Now, if fetching a URL takes more than 5 seconds, it will print a message to that effect.
2013-06-07	Remove obsolete EOF checks	Eelco Dolstra	1	-26/+18

2013-06-07	Process stderr from substituters while doing have/info queries	Eelco Dolstra	4	-9/+59

2013-06-07	Buffer reads from the substituter	Eelco Dolstra	2	-10/+27
	This greatly reduces the number of system calls.
2013-06-05	download-from-binary-cache.pl: Fix race condition	Eelco Dolstra	1	-3/+4
	Fixes the error "DBD::SQLite::db do failed: column url is not unique".
2013-06-05	Update the default binary cache URL to cache.nixos.org	Eelco Dolstra	4	-9/+9

2013-06-04	download-from-binary-cache.pl: Treat a 403 error as a 404	Eelco Dolstra	1	-2/+2
	Amazon S3 returns HTTP status code 403 if a file doesn't exist and the user has no permission to list the contents of the bucket. So treat it as 404 (meaning it's cached in the NARExistence table).
2013-05-29	build-remote.pl: Remove meaningless signing when importing the output paths	Eelco Dolstra	1	-3/+1
	The "$UID != 0" makes no sense: if the local side has write access to the Nix store (which is always the case) then it doesn't matter if we're root - we can import unsigned paths either way.
2013-05-29	.bashrc -> .profile	Eelco Dolstra	2	-2/+2

2013-05-23	nix-store --export: Export paths in topologically sorted order	Eelco Dolstra	2	-2/+4
	Fixes #118.
2013-05-23	build-remote.pl: Copy all outputs in one operation	Eelco Dolstra	1	-5/+5

2013-05-23	build-remote.pl: Indicate if remote machine is refusing builds	Eelco Dolstra	1	-2/+3
	Fixes #120.
2013-05-16	Show function names in error messages	Eelco Dolstra	5	-8/+43
	Functions in Nix are anonymous, but if they're assigned to a variable/attribute, we can use the variable/attribute name in error messages, e.g. while evaluating `concatMapStrings' at `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/pkgs/lib/strings.nix:18:25': ...
2013-05-16	Show which function argument was unexpected	Eelco Dolstra	1	-5/+9
	Fixes #116.
2013-05-16	Shut up a compiler warning	Eelco Dolstra	1	-1/+1

2013-05-15	download-from-binary-cache.pl: Get rid of an uninitialized value warning	Eelco Dolstra	1	-1/+1
	Reported by Pablo Costa.
2013-05-13	Bump version	Eelco Dolstra	1	-1/+1

2013-05-13	Bump release date	Eelco Dolstra	1	-1/+1

2013-05-10	build-remote.pl: Properly close the SSH connection between attempts	Eelco Dolstra	2	-3/+5

2013-05-10	build-remote.pl: Pass /dev/null as SSH's stdin	Eelco Dolstra	1	-1/+1
	Otherwise it will set the parent's stdin to non-blocking mode, causing the subsequent read of the set of inputs/outputs to fail randomly. That's insane.
2013-05-10	build-remote.pl: Allow a machine to refuse a build	Eelco Dolstra	1	-1/+3
	Before selecting a machine, build-remote.pl will try to run the command "nix-builds-inhibited" on the machine. If this command exists and returns a 0 exit code, then the machine won't be used. It's up to the user to provide this command, but it would typically be a script that checks whether there is enough disk space and whether the load is not too high.
2013-05-10	In trace messages, don't print the output path	Eelco Dolstra	1	-19/+15
	This doesn't work if there is no output named "out". Hydra didn't use it anyway.
2013-05-09	Communicate build timeouts to Hydra	Eelco Dolstra	1	-7/+11

2013-05-09	build-remote.pl: Create one process fewer on the remote side	Eelco Dolstra	1	-1/+1

2013-05-09	build-remote.pl: Enforce timeouts locally	Eelco Dolstra	2	-6/+3
	Don't pass --timeout / --max-silent-time to the remote builder. Instead, let the local Nix process terminate the build if it exceeds a timeout. The remote builder will be killed as a side-effect. This gives better error reporting (since the timeout message from the remote side wasn't properly propagated) and handles non-Nix problems like SSH hangs.
2013-05-08	Build Fedora 18 RPMs	Eelco Dolstra	1	-2/+2

2013-05-07	Update release date	Eelco Dolstra	1	-1/+1

2013-05-07	Add option ‘extra-binary-caches’	Eelco Dolstra	2	-3/+24
	This allows providing additional binary caches, useful in scripts like Hydra's build reproduction scripts, in particular because untrusted caches are ignored.
2013-05-07	Build Debian 7.0 debs	Eelco Dolstra	1	-0/+2

2013-05-03	Build Ubuntu 13.04 debs	Eelco Dolstra	1	-0/+2

2013-05-03	Update release notes	Eelco Dolstra	1	-2/+3

2013-05-03	nix-copy-closure: Show a proper error message if no host name is given	Eelco Dolstra	1	-0/+2

2013-05-03	Fixing the pv position regarding compression	Lluís Batlle i Rossell	2	-2/+2
	Problem noticed by niksnut.
2013-05-03	Fixing the pv reference; I didn't mean to change it	Lluís Batlle i Rossell	1	-1/+1
