bf0dde9597 * Always print hook output on stderr, even if --no-build-output is 
set.
* In the build hook, print a trace message to allow Hydra to pick up
  the name of the remote machine used for the build.

80e722278c * When using the build hook, distinguish between the stderr of the 
hook script proper, and the stdout/stderr of the builder.  Only the
  latter should be saved in /nix/var/log/nix/drvs.
* Allow the verbosity to be set through an option.
* Added a flag --quiet to lower the verbosity level.

766f708418 * Experimental feature: allow a derivation to tell the build hook that 
it requires a certain feature on the build machine, e.g.

    requiredSystemFeatures = [ "kvm" ];

  We need this in Hydra to make sure that builds that require KVM
  support are forwarded to machines that have KVM support.  Probably
  this should also be enforced for local builds.

e437b08250 * Made the build hook mechanism more efficient. Rather than starting 
the hook every time we want to ask whether we can run a remote build
  (which can be very often), we now reuse a hook process for answering
  those queries until it accepts a build.  So if there are N
  derivations to be built, at most N hooks will be started.

1a396f3789 * Don't call "cat". 2010-08-25 12:19:30 +00:00
Eelco Dolstra
95deba581d * In the build hook, temporarily register the derivation and its 
output as GC roots.  This prevents a race if the garbage collector
  is running during the build.

1e5f5ea2e9 * Correctly handle SSH failing to establish a connection. Because 
this didn't work right, the build hook wouldn't fall back to using
  other machines of the desired type.

5f9aad44ca * nix-build: recognise --cores. 2010-08-11 15:28:02 +00:00

587dc8aa00 * Sync with the trunk. 2010-08-04 17:48:29 +00:00

532d766c27 * Don't barf if the source NAR for a patch has disappeared. 2010-07-21 11:30:23 +00:00

560ab22f7d * Ignore packages that don't have a version. 
* Work on a manifest instead of a channel directory.

819548d92f * Pass `--fallback' to the remote build to ignore failing 
substituters.

c778ed1768 * Fix the copy-from-other-stores substituter. 2010-04-26 13:39:55 +00:00
Eelco Dolstra
05fbf61f0e * nix-prefetch-url depends on sed (see 
http://hydra.nixos.org/build/311170).
 2010-03-05 18:26:47 +00:00
Eelco Dolstra
68e55cd9da * Since Hydra now escapes +', =' and `?' to %NN in URIs, 
nix-prefetch-url should unescape them, because `%' is not a valid
  character in store path names.

719cebcac2 * "Fix" incorrect help message. 2010-02-04 09:38:09 +00:00
Eelco Dolstra
443673620d * Don't use ssh's -f flag since it leads to lots of lingering ssh 
processes.

7ec5a65925 * Doh! The scope of $slotLock should extend to the end of the script, 
because otherwise the lock will be released at the end of the while
  loop.

c9b2d80bcd * Typo. 2010-02-04 02:05:34 +00:00
Eelco Dolstra
3cfe65e516 * Doh! Calling `system' in an END block causes the exit status in $? 
to be changed to 0.

e51a276907 * Remove the `cat' calls when not using --gzip. 2010-02-04 01:39:23 +00:00

408913bbaf * Revert r19796 for now. 2010-02-04 00:12:57 +00:00

c45de33c67 * Respect @sysconfdir@. 2010-02-03 21:13:37 +00:00
Eelco Dolstra
d0c32dc135 * In the build hook, if connecting to a machine fails, try the other 
machines of the right type (if available).  This makes the build
  farm more robust to failures.

f56a039775 * Use SSH connection sharing in the remote build script. 
* Removed the Cygwin password hack since the problem is apparently
  fixed in Visual Studio.
 2010-02-03 20:12:18 +00:00
Eelco Dolstra
bc1e478db1 * nix-copy-closure: start only one SSH connection to the server, or 
recycle an already existing connection (using  OpenSSH's connection
  sharing feature).
 2010-02-03 15:34:52 +00:00
Eelco Dolstra
e839802720 * Don't do a chdir to $tmpDir. It's not necessary, and Windows doesn't 
support deleting the current directory.
 2010-02-02 15:29:18 +00:00
Eelco Dolstra
50e34891f0 * Disable gzip compression in build-remote.pl because it puts too much 
load on the Hydra build farm (where it's unnecessary anyway because
  it has a fast connection to the build machines).  In any case,
  compression can be enabled by using the `-C' option to ssh.

7ca9972636 * When doing a nix-pull, remove old manifests downloaded from the same 
URL.  This prevents lots of old cruft accumulating in
  /nix/var/nix/manifests.

c4c84d1edb * nix-build: be less verbose. 2009-12-09 18:08:28 +00:00
Eelco Dolstra
997db91e07 * Don't pass -K. It should really inherit the setting of the calling 
Nix though.

Eelco Dolstra
3392d32e8b * In nix-pull/nix-channel, create the manifests directory if it 
doesn't exist.  The Debian packages don't include the manifests
  directory, so nix-channel would silently skip doing a nix-pull,
  resulting in everything being built from source.  Thanks to Juan
  Pedro Bolívar Puente.

86408b3f47 * build-remote.pl: Pick machines in a round-robin order, rather than 
giving jobs to the first machine until it hits its job limit, then
  the second machine and so on.  This should improve utilisation of
  the Hydra build farm a lot.  Also take an optional speed factor
  into account to cause fast machines to be preferred over slower
  machines with a similar load.
 2009-09-17 15:48:17 +00:00
Eelco Dolstra
57e0d73c77 * build-remote.pl: allow the system type to be a comma-separated list 
of system types.  Don't treat the x86_64-linux system type
  specially.
 2009-09-17 13:51:04 +00:00

20b6f94b65 * nix-build: pass the --show-trace flag. 2009-07-15 09:10:38 +00:00
Eelco Dolstra
f24cf5d303 * nix-build: if nix-instantiate or nix-store fails due to a signal 
(e.g. out of memory or a segfault), print an error message.
  Otherwise the user doesn't see anything.
 2009-06-10 11:30:34 +00:00

c710fe540e * Machines of type x86_64-linux can do i686-linux builds. 2009-04-21 12:42:47 +00:00

0460ea4c39 * Cleanup. 2009-04-16 09:27:33 +00:00
Eelco Dolstra
096affb55b * Update the mtime on the lock file to make it easy to see when a slot 
was last used.
 2009-03-29 18:40:44 +00:00
Eelco Dolstra
737423a89c * Use polling to wait for a remote build slot when using a build hook 
(that is, call the build hook with a certain interval until it
  accepts the build).
* build-remote.pl was totally broken: for all system types other than
  the local system type, it would send all builds to the *first*
  machine of the appropriate type.
 2009-03-29 18:00:45 +00:00
Eelco Dolstra
47706e3924 * nix-copy-closure: compute the closure in one call to nix-store, 
which is much faster.
 2009-03-28 21:10:29 +00:00
Eelco Dolstra
3a2bbe7f8a * Simplify communication with the hook a bit (don't use file 
descriptors 3/4, just use stdin/stderr).
 2009-03-28 19:29:55 +00:00
Eelco Dolstra
7fb548aa26 * Clean up the output a bit. 2009-03-28 16:12:46 +00:00
Eelco Dolstra
7e05b8b75e * Future proofing: assume we can read manifests up to version 10 
(which should therefore be backwards compatible).

b88460bcbc * Disregard the Hash field in manifests. 2009-03-19 09:47:34 +00:00
Eelco Dolstra
2897286487 * Unify exportReferencesGraph and exportBuildReferencesGraph, and make 
sure that it works as expected when you pass it a derivation.  That
  is, we have to make sure that all build-time dependencies are built,
  and that they are all in the input closure (otherwise remote builds
  might fail, for example).  This is ensured at instantiation time by
  adding all derivations and their sources to inputDrvs and inputSrcs.

1dcf208f56 * Clean up some tests (use nix-build where appropriate). 2009-03-18 13:15:55 +00:00

1273d355ac * nix-install-package: don't pollute /nix/var/nix/manifests. 2009-02-27 14:06:38 +00:00
