2012-07-25	import: If the path is a valid .drv file, parse it and generate a derivation ↵	Shea Levy	3	-2/+48
	attrset. The generated attrset has drvPath and outPath with the right string context, type 'derivation', outputName with the right name, all with a list of outputs, and an attribute for each output. I see three uses for this (though certainly there may be more): * Using derivations generated by something besides nix-instantiate (e.g. guix) * Allowing packages provided by channels to be used in nix expressions. If a channel installed a valid deriver for each package it provides into the store, then those could be imported and used as dependencies or installed in environment.systemPackages, for example. * Enable hydra to be consistent in how it treats inputs that are outputs of another build. Right now, if an input is passed as an argument to the job, it is passed as a derivation, but if it is accessed via NIX_PATH (i.e. through the <> syntax), then it is a path that can be imported. This is problematic because the build being depended upon may have been built with non-obvious arguments passed to its jobset file. With this feature, hydra can just set the name of that input to the path to its drv file in NIX_PATH
2012-07-25	Disable tests temporarily	Shea Levy	1	-1/+1

2012-07-23	Handle platforms that don't support linking to a symlink	Eelco Dolstra	2	-2/+19
	E.g. Darwin doesn't allow this.
2012-07-23	Unlink the right file	Eelco Dolstra	1	-2/+2

2012-07-23	Add a test for Nix store optimisation	Eelco Dolstra	2	-1/+27

2012-07-23	Garbage collect unused links in /nix/store/.links	Eelco Dolstra	2	-0/+39
	Incremental optimisation requires creating links in /nix/store/.links to all files in the store. However, this means that if we delete a store path, no files are actually deleted because links in /nix/store/.links still exists. So we need to check /nix/store/.links for files with a link count of 1 and delete them.
2012-07-23	Automatically optimise the Nix store when a new path is added	Eelco Dolstra	5	-10/+45
	Auto-optimisation is enabled by default. It can be turned off by setting auto-optimise-store to false in nix.conf.
2012-07-23	optimiseStore(): Use a content-addressed file store in /nix/store/.links	Eelco Dolstra	3	-115/+110
	optimiseStore() now creates persistent, content-addressed hard links in /nix/store/.links. For instance, if it encounters a file P with hash H, it will create a hard link P' = /nix/store/.link/<H> to P if P' doesn't already exist; if P' exist, then P is replaced by a hard link to P'. This is better than the previous in-memory map, because it had the tendency to unnecessarily replace hard links with a hard link to whatever happened to be the first file with a given hash it encountered. It also allows on-the-fly, incremental optimisation.
2012-07-23	nix-build: Support the ‘-’ argument to build an expression from stdin	Eelco Dolstra	1	-0/+4

2012-07-23	Use lutimes() if available to canonicalise the timestamp of symlinks	Eelco Dolstra	2	-9/+21
	Also use utimes() instead of utime() if lutimes() is not available.

2012-07-18	Set release date	Eelco Dolstra	1	-1/+1

2012-07-17	Add function queryPathFromHashPart()	Eelco Dolstra	9	-0/+67
	To implement binary caches efficiently, Hydra needs to be able to map the hash part of a store path (e.g. "gbg...zr7") to the full store path (e.g. "/nix/store/gbg...kzr7-subversion-1.7.5"). (The binary cache mechanism uses hash parts as a key for looking up store paths to ensure privacy.) However, doing a search in the Nix store for /nix/store/<hash>* is expensive since it requires reading the entire directory. queryPathFromHashPart() prevents this by doing a cheap database lookup.
2012-07-17	queryPathInfo(): return hash in base-32 if desired	Eelco Dolstra	1	-2/+2
	Cherry-picked from the no-manifests branch.
2012-07-17	Return an exit code of 100 for cached failed builds	Eelco Dolstra	1	-0/+1
	Exit code 100 should be returned for all permanent failures. This includes cached failures. Fixes #34.

2012-06-27	nix-store -r: do substitutions in parallel	Eelco Dolstra	11	-25/+30
	I.e. when multiple non-derivation arguments are passed to ‘nix-store -r’ to be substituted, do them in parallel.
2012-06-27	Mount an empty /dev/shm tmpfs in the chroot	Eelco Dolstra	1	-0/+6
	This ensures that whatever the builder writes in /dev/shm is automatically cleaned up.
2012-06-27	Check the return code of the clone() call	Eelco Dolstra	1	-1/+2

2012-06-25	When using chroots, use a private PID namespace	Eelco Dolstra	2	-156/+186
	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().
2012-06-25	Use a private UTS namespace to provide a deterministic host/domain name to ↵	Eelco Dolstra	1	-1/+7
	builders In chroot builds, set the host name to "localhost" and the domain name to "(none)" (the latter being the kernel's default). This improves determinism a bit further. P.S. I have to idea what UTS stands for.
2012-06-23	Update release notes	Eelco Dolstra	1	-1/+15

2012-06-23	Improve error message	Eelco Dolstra	1	-1/+1

2012-06-23	In chroot builds, use a private SysV IPC namespace	Eelco Dolstra	1	-12/+19
	This improves isolation a bit further, and it's just one extra flag in the unshare() call. P.S. It would be very cool to use CLONE_NEWPID (to put the builder in a private PID namespace) as well, but that's slightly more risky since having a builder start as PID 1 may cause problems.
2012-06-23	In chroot builds, use a private network namespace	Eelco Dolstra	1	-6/+31
	On Linux it's possible to run a process in its own network namespace, meaning that it gets its own set of network interfaces, disjunct from the rest of the system. We use this to completely remove network access to chroot builds, except that they get a private loopback interface. This means that: - Builders cannot connect to the outside network or to other processes on the same machine, except processes within the same build. - Vice versa, other processes cannot connect to processes in a chroot build, and open ports/connections do not show up in "netstat". - If two concurrent builders try to listen on the same port (e.g. as part of a test), they no longer conflict with each other. This was inspired by the "PrivateNetwork" flag in systemd.
2012-06-18	Support socket-based, on-demand activation of the Nix daemon with systemd	Eelco Dolstra	1	-30/+46
	Systemd can start the Nix daemon on demand when the Nix daemon socket is first accessed. This is signalled through the LISTEN_FDS environment variable, so all we need to do is check for that and then use file descriptor 3 as the listen socket instead of creating one ourselves.
