You may have noticed that hydra.gnu.org has been, hmm, unhealthy
lately.  There are several bugs in the offload hook that were fixed
recently, notably fixing errors such as:

  guix build: error: lstat: No such file or directory: ...foo.drv

You may have also seen:

  derivation was garbage-collected prior to build

This one should now be fixed, on the Hydra side:

  https://github.com/NixOS/hydra/commit/cc4645659896113cb8677110a1ed768405709296

So it’s not optimal yes, but making progress.

Thanks,
Ludo’.

There are still quite a few of the following kind:
   guix build: error: open-file: No such file or directory: "/gnu/store/gpcxqii07ivdk6ny8svhayw7hc98gh8i-xnee-3.18.drv"
See, for instance,
   http://hydra.gnu.org/build/49330
I restarted most of them, but kept this one for reference.

And there are others that, when one tries to restart them, reply with
   500 Internal Server Error
   This build cannot be restarted.
For instance,
   http://hydra.gnu.org/build/47968
What can we do there?

As far as I can tell, this one stil persists, see

Hmm, given its date, this one could be problematic.  However, there’s
still the possibility that this is a cached failure (guix-daemon runs
with --cache-failures on hydra.gnu.org.)

I installed the offload fixes (specifically 4b00f34 plus a related setup
issue on chapters.gnu.org) on Apr. 8th.  This one dates from before;
presumably its .drv has been GC’d, which is why it cannot be restarted.
So no worries on this one.

Going to http://hydra.gnu.org/build/49569/ shows that the texlive builds
were actually aborted.  The “Nix error output” box shows this:

So the problem occurred while retrieving and restoring the build result
(the log shows just these two lines because apparently, the result was
already available on the build machine hydra.gnunet.org–which is no
surprise given that /gnu is 1.5T on that machine, vs. 400G on
hydra.gnu.org.)

The ‘mkdir’ error here suggests that the temporary place were we are
restoring, /gnu/store/guix-8uVCz3, has been removed right in the middle
of the process by the GC.

I believe this is fixed by 9132b9b.

Thanks!

Okay for the future. But can we force hydra to recompile the package now
instead of only after the next change in the package or one of its inputs?
Particularly annoying is gnu-pw-mgr:
   http://hydra.gnu.org/build/45105/nixlog/3/tail-reload
From the error message, it looks as if the new download location of 8bae41a
has not been taken into account.

Thanks.

I haven’t forgotten about the issue, but my investigations haven’t yet
been fruitful.

Actually no (I’ve seen other occurrences of that in the meantime.)

9132b9b had a thinko, which is (hopefully!) fixed by 6071b55.  I’ve just
installed it on hydra.gnu.org.

I did some testing and I think 30ce801 solves this problem.

The issue was actually not a GC issue, but a synchronization issue.
Since I introduced ‘call-with-compressed-output-port’ & co., the
‘send-files’ and ‘retrieve-files’ procedures in offload.scm no longer
explicitly waited for the lsh process to complete.

Thus, the ‘transfer-and-offload’ procedure could call the ‘offload’
procedure (which invokes the remote ‘guix build’) before ‘send-files’
was done uploading the .drv file, hence the error.

I’ve just installed the change on hydra.gnu.org, so let’s see how things
work now.

Thanks,
Ludo’.

There was another problem with that “fix”, namely that the daemon
ignores normal GC roots pointing to “abnormal” store files like
/gnu/store/guix-8uVCz3.

This led to the (now abandoned) proposal at
<https://lists.gnu.org/archive/html/guix-devel/2014-04/msg00198.html>.
I finally came up with a simpler solution in commit 50db7d8: a
connection to the daemon is opened for the sake of holding a per-process
GC root to that temporary store file.
