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.

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.

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.

997db91e07 * Don't pass -K. It should really inherit the setting of the calling
Nix though.

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.

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.

096affb55b * Update the mtime on the lock file to make it easy to see when a slot
was last used.

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.

47706e3924 * nix-copy-closure: compute the closure in one call to nix-store,
which is much faster.

3a2bbe7f8a * Simplify communication with the hook a bit (don't use file
descriptors 3/4, just use stdin/stderr).

1bb0f1e84b * Build hook: compress the transferred data. 2009-02-03 10:34:15 +00:00

b682fae9d9 * Build hooks: use nix-store --import. This prevents a redundant
scan for runtime dependencies (i.e. the local machine shouldn't do a
  scan that the remote machine has already done).  Also pipe directly
  into `nix-store --import': don't use a temporary file.

019176137f * When using a build hook, distinguish between transient failures
(e.g. an SSH connection problem) and permanent failures (i.e. the
  builder failed).  This matters to Hydra (it wants to know whether it
  makes sense to retry a build).

bcfe98acff * Prefer building on a remote machine over a local machine. This
makes more sense for the build farm, otherwise every nix-store
  invocation will lead to at least one local build.  Will come up with
  a better solution later...

909fbb9de1 * When using build hooks, for any nix-store -r build operation, it is
necessary that at least one build hook doesn't return "postpone",
  otherwise nix-store will barf ("waiting for a build slot, yet there
  are no running children").  So inform the build hook when this is
  the case, so that it can start a build even when that would exceed
  the maximum load on a machine.

5dfba0b4db * Force allocation of a pseudo-terminal to clean up the remote
nix-store process when the connection is interrupted.

9fd9c4c635 * Support multiple system types per remote machine, e.g. a machine
list like

    root@example.org x86_64-linux /root/.ssh/id_buildfarm 1
    root@example.org i686-darwin  /root/.ssh/id_buildfarm 1

  This is possible when the Nix installation on example.org itself has
  remote builds enabled.
