2017-06-12	Don't run pre-build-hook if we don't have a derivation	Eelco Dolstra
	This fixes a build failure on OS X when using Hydra or Nix 1.12's build-remote (since they don't copy the derivation to the build machine).
2017-06-07	Don't show flags from config settings in "nix --help"	Eelco Dolstra

2017-06-07	nix: Make all options available as flags	Eelco Dolstra
	Thus, instead of ‘--option <name> <value>’, you can write ‘--<name> <value>’. So --option http-connections 100 becomes --http-connections 100 Apart from brevity, the difference is that it's not an error to set a non-existent option via --option, but unrecognized arguments are fatal. Boolean options have special treatment: they're mapped to the argument-less flags ‘--<name>’ and ‘--no-<name>’. E.g. --option auto-optimise-store false becomes --no-auto-optimise-store
2017-06-06	Disable the build user mechanism on all platforms except Linux and OS X	Eelco Dolstra

2017-06-06	Always use the Darwin sandbox	Eelco Dolstra
	Even with "build-use-sandbox = false", we now use sandboxing with a permissive profile that allows everything except the creation of setuid/setgid binaries.
2017-05-31	Remove listxattr assertion	Eelco Dolstra
	It appears that sometimes, listxattr() returns a different value for the query case (i.e. when the buffer size is 0).
2017-05-31	OS X sandbox: Improve builtin sandbox profile	Eelco Dolstra
	Also, add rules to allow fixed-output derivations to access the network. These rules are sufficient to build stdenvDarwin without any __sandboxProfile magic.
2017-05-31	OS X sandbox: Don't use a deterministic $TMPDIR	Eelco Dolstra
	This doesn't work because the OS X sandbox cannot bind-mount path to a different location.
2017-05-31	OS X sandbox: Store .sb file in $TMPDIR rather than the Nix store	Eelco Dolstra
	The filename used was not unique and owned by the build user, so builds could fail with error: while setting up the build environment: cannot unlink ‘/nix/store/99i210ihnsjacajaw8r33fmgjvzpg6nr-bison-3.0.4.drv.sb’: Permission denied
2017-05-30	Darwin sandbox: Use sandbox-defaults.sb	Eelco Dolstra
	Issue #759. Also, remove nix.conf from the sandbox since I don't really see a legitimate reason for builders to access the Nix configuration.
2017-05-30	Darwin sandbox: Disallow creating setuid/setgid binaries	Eelco Dolstra
	Suggested by Daiderd Jordan.
2017-05-30	Fix seccomp build failure on clang	Eelco Dolstra
	Fixes src/libstore/build.cc:2321:45: error: non-constant-expression cannot be narrowed from type 'int' to 'scmp_datum_t' (aka 'unsigned long') in initializer list [-Wc++11-narrowing]
2017-05-30	Shut up some clang warnings	Eelco Dolstra

2017-05-30	Add a seccomp rule to disallow setxattr()	Eelco Dolstra

2017-05-30	canonicalisePathMetaData(): Remove extended attributes / ACLs	Eelco Dolstra
	EAs/ACLs are not part of the NAR canonicalisation. Worse, setting an ACL allows a builder to create writable files in the Nix store. So get rid of them. Closes #185.
2017-05-30	Require seccomp only in multi-user setups	Eelco Dolstra

2017-05-29	Fix seccomp initialisation on i686-linux	Eelco Dolstra

2017-05-29	Add a seccomp filter to prevent creating setuid/setgid binaries	Eelco Dolstra
	This prevents builders from setting the S_ISUID or S_ISGID bits, preventing users from using a nixbld* user to create a setuid/setgid binary to interfere with subsequent builds under the same nixbld* uid. This is based on aszlig's seccomp code (47f587700d646f5b03a42f2fa57c28875a31efbe). Reported by Linus Heckemann.
2017-05-29	Fix nix-copy-closure test	Eelco Dolstra
	Fixes client# error: size mismatch importing path ‘/nix/store/ywf5fihjlxwijm6ygh6s0a353b5yvq4d-libidn2-0.16’; expected 0, got 120264 This is mostly an artifact of the NixOS VM test environment, where the Nix database doesn't contain hashes/sizes. http://hydra.nixos.org/build/53537471
2017-05-29	Fix typo	Eelco Dolstra

2017-05-24	Merge branch 'nar-accessor-tree' of https://github.com/bennofs/nix	Eelco Dolstra

2017-05-16	Improve progress indicator	Eelco Dolstra

2017-05-15	nar-accessor.cc: remove unused member NarIndexer::currentName	Benno Fünfstück

2017-05-15	nar-accessor: non-recursive NarMember::find	Benno Fünfstück
	This avoids a possible stack overflow if directories are very deeply nested.
2017-05-15	Simplify fixed-output check	Eelco Dolstra

2017-05-15	Add --with-sandbox-shell configure flag	Eelco Dolstra
	And add a 116 KiB ash shell from busybox to the release build. This helps to make sandbox builds work out of the box on non-NixOS systems and with diverted stores.
2017-05-15	Linux sandbox: Don't barf on invalid paths	Eelco Dolstra
	This is useful when we're using a diverted store (e.g. "--store local?root=/tmp/nix") in conjunction with a statically-linked sh from the host store (e.g. "sandbox-paths =/bin/sh=/nix/store/.../bin/busybox").
2017-05-15	nar-accessor: use tree, fixes readDirectory missing children	Benno Fünfstück
	Previously, if a directory `foo` existed and a file `foo-` (where `-` is any character that is sorted before `/`), then `readDirectory` would return an empty list. To fix this, we now use a tree where we can just access the children of the node, and do not need to rely on sorting behavior to list the contents of a directory.
2017-05-11	Add an option for extending the user agent header	Eelco Dolstra
	This is useful e.g. for distinguishing traffic to a binary cache (e.g. certain machines can use a different tag in the user agent).
2017-05-11	Fix typo	Eelco Dolstra

2017-05-11	Tweak error message	Eelco Dolstra

2017-05-11	Change the meaning of info.ultimate	Eelco Dolstra
	It now means "paths that were built locally". It no longer includes paths that were added locally. For those we don't need info.ultimate, since we have the content-addressability assertion (info.ca).
2017-05-11	LocalStore::addToStore(): Check info.narSize	Eelco Dolstra
	It allowed the client to specify bogus narSize values. In particular, Downloader::downloadCached wasn't setting narSize at all.
2017-05-08	Minor cleanup	Eelco Dolstra

2017-05-08	Linux sandbox: Fix compatibility with older kernels	Eelco Dolstra

2017-05-08	Remove superfluous #ifdef	Eelco Dolstra

2017-05-05	Make the location of the build directory in the sandbox configurable	Eelco Dolstra
	This is mostly for use in the sandbox tests, since if the Nix store is under /build, then we can't use /build as the build directory.
2017-05-04	Linux sandbox: Use /build instead of /tmp as $TMPDIR	Eelco Dolstra
	There is a security issue when a build accidentally stores its $TMPDIR in some critical place, such as an RPATH. If TMPDIR=/tmp/nix-build-..., then any user on the system can recreate that directory and inject libraries into the RPATH of programs executed by other users. Since /build probably doesn't exist (or isn't world-writable), this mitigates the issue.
2017-05-02	LocalStoreAccessor: Fix handling of diverted stores	Eelco Dolstra

2017-05-02	Replace $NIX_REMOTE_SYSTEMS with an option "builder-files"	Eelco Dolstra
	Also, to unify with hydra-queue-runner, allow it to be a list of files.
2017-05-02	build-remote: Fix fallback to other machines when connecting fails	Eelco Dolstra
	Opening an SSHStore or LegacySSHStore does not actually establish a connection, so the try/catch block here did nothing. Added a Store::connect() method to test whether a connection can be established.
2017-05-02	Add an option for specifying remote builders	Eelco Dolstra
	This is useful for one-off situations where you want to specify a builder on the command line instead of having to mess with nix.machines. E.g. $ nix-build -A hello --argstr system x86_64-darwin \ --option builders 'root@macstadium1 x86_64-darwin' will perform the specified build on "macstadium1". It also removes the need for a separate nix.machines file since you can specify builders in nix.conf directly. (In fact nix.machines is yet another hack that predates the general nix.conf configuration file, IIRC.) Note: this option is supported by the daemon for trusted users. The fact that this allows trusted users to specify paths to SSH keys to which they don't normally have access is maybe a bit too much trust...
2017-05-02	Factor out machines.conf parsing	Eelco Dolstra
	This allows hydra-queue-runner to use it.
2017-05-02	build-hook: If there are no machines defined, quit permanently	Eelco Dolstra

2017-05-02	build-remote: Ugly hackery to get build logs to work	Eelco Dolstra
	The build hook mechanism expects build log output to go to file descriptor 4, so do that.
2017-05-01	build-remote: Don't require signatures	Eelco Dolstra
	This restores the old behaviour.
2017-05-01	Support arbitrary store URIs in nix.machines	Eelco Dolstra
	For backwards compatibility, if the URI is just a hostname, ssh:// (i.e. LegacySSHStore) is prepended automatically. Also, all fields except the URI are now optional. For example, this is a valid nix.machines file: local?root=/tmp/nix This is useful for testing the remote build machinery since you don't have to mess around with ssh.
2017-05-01	Implement LegacySSHStore::buildDerivation()	Eelco Dolstra
	This makes LegacySSHStore usable by build-remote and hydra-queue-runner.
2017-05-01	Chomp log output from the build hook	Eelco Dolstra

2017-05-01	Remove $NIX_BUILD_HOOK and $NIX_CURRENT_LOAD	Eelco Dolstra
	This is to simplify remote build configuration. These environment variables predate nix.conf. The build hook now has a sensible default (namely build-remote). The current load is kept in the Nix state directory now.
