Eelco Dolstra d5a076c36f Add option ‘build-extra-chroot-dirs’ 
This is useful for extending (rather than overriding) the default set
of chroot paths.

Eelco Dolstra 4c4b219c07 Call commonChildInit() before doing chroot init 
This ensures that daemon clients see error messages from the chroot
setup.

Eelco Dolstra e0d7d0e45c findRoots(): Prevent a call to lstat() 
This means that getting the roots from /nix/var/nix/.../hydra-roots
doesn't need any I/O other than reading the directory.

Eelco Dolstra daf3f2c11f Make readDirectory() return inode / file type 2014-08-01 17:14:28 +02:00
Eelco Dolstra 1c208f2b7e Allow regular files as GC roots 
If a root is a regular file, then its name must denote a store
path. For instance, the existence of the file

  /nix/var/nix/gcroots/per-user/eelco/hydra-roots/wzc3cy1wwwd6d0dgxpa77ijr1yp50s6v-libxml2-2.7.7

would cause

  /nix/store/wzc3cy1wwwd6d0dgxpa77ijr1yp50s6v-libxml2-2.7.7

to be a root.

This is useful because it involves less I/O (no need for a readlink()
call) and takes up less disk space (the symlink target typically takes
up a full disk block, while directory entries are packed more
efficiently). This is particularly important for hydra.nixos.org,
which has hundreds of thousands of roots, and where reading the roots
can take 25 minutes.

Eelco Dolstra 3d221a7bb1 Rename nixPath to __nixPath 
The name ‘nixPath’ breaks existing code.

Eelco Dolstra 67937907ca nix-daemon: Pass on the user's $SSH_AUTH_SOCK to the SSH substituter 2014-07-25 18:02:48 +02:00
Eelco Dolstra 71a20d4d95 Change the default for use-ssh-substituter to ‘true’ 
Now you only have to pass ‘--option ssh-substituter-hosts
nix-ssh@bla’ to enable SSH substitution.

Fixes #2.
 2014-07-24 17:46:58 +02:00
Eelco Dolstra 1a44f1cb65 nix-copy-closure: Drop --bzip2, --xz, --show-progress 
These are too difficult to implement via nix-store --serve.

‘--show-progress’ could be re-implemented fairly easily via a
sink/source wrapper class.

Eelco Dolstra d7a92ed4a9 nix-store --serve: Only monitor stdin during builds 
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.

Eelco Dolstra a6ab3cf35f tests/remote-builds.nix: Don't try cache.nixos.org 2014-07-24 11:50:05 +02:00
Eelco Dolstra 0fae20c362 Use pthread_cancel instead of a signal 
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.

Eelco Dolstra 78224cd871 nix-store --serve: Monitor for client disconnects 
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 19:26:34 +02:00
Eelco Dolstra 49fe9592a4 nix-daemon: Use a thread instead of SIGPOLL to catch client disconnects 
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.
