Eelco Dolstra acb8facbbc Fix potential segfault in waitForInput()
Since the addition of build-max-log-size, a call to
handleChildOutput() can result in cancellation of a goal.  This
invalidated the "j" iterator in the waitForInput() loop, even though
it was still used afterwards.  Likewise for the maxSilentTime
handling.

Probably fixes #231.  At least it gets rid of the valgrind warnings.

Eelco Dolstra 49009573bc Don't interpret strings as format strings
Ludo reported this error:

  unexpected Nix daemon error: boost::too_few_args: format-string refered to more arguments than were passed

coming from this line:

  printMsg(lvlError, run.program + ": " + string(err, 0, p));

The problem here is that the string ends up implicitly converted to a
Boost format() object, so % characters are treated specially.  I
always assumed (wrongly) that strings are converted to a format object
that outputs the string as-is.

Since this assumption appears in several places that may be hard to
grep for, I've added some C++ type hackery to ensures that the right
thing happens.  So you don't have to worry about % in statements like

  printMsg(lvlError, "foo: " + s);

or

  throw Error("foo: " + s);

Ludovic Courtès 24cb65efc3 Make /dev/kvm optional
The daemon now creates /dev deterministically (thanks!).  However, it
expects /dev/kvm to be present.

The patch below restricts that requirement (1) to Linux-based systems,
and (2) to systems where /dev/kvm already exists.

I’m not sure about the way to handle (2).  We could special-case
/dev/kvm and create it (instead of bind-mounting it) in the chroot, so
it’s always available; however, it wouldn’t help much since most likely,
if /dev/kvm missing, then KVM support is missing.

Ludovic Courtès 51800e06de Allow recovery from isValidPath RPCs with an invalid path
Currently, clients cannot recover from an isValidPath RPC with an
invalid path parameter because the daemon closes the connection when
that happens.

More precisely:

  1. in performOp, wopIsValidPath case, ‘readStorePath’ raises an
     ‘Error’ exception;

  2. that exception is caught by the handler in ‘processConnection’;

  3. the handler determines errorAllowed == false, and thus exits after
     sending the message.

This last part is fixed by calling ‘startWork’ early on, as in the patch
below.

The same reasoning could be applied to all the RPCs that take one or
more store paths as inputs, but isValidPath is, by definition, likely to
be passed invalid paths in the first place, so it’s important for this
one to allow recovery.

Eelco Dolstra c9f6232304 Correctly detect infinite recursion in function application
If we're evaluating some application ‘v = f x’, we can't store ‘f’
temporarily in ‘v’, because if ‘f x’ refers to ‘v’, it will get ‘f’
rather than an infinite recursion error.

Unfortunately, this breaks the tail call optimisation introduced in
c897bac549.

Fixes #217.

Eelco Dolstra 29cde917fe Fix deadlock in SubstitutionGoal
We were relying on SubstitutionGoal's destructor releasing the lock,
but if a goal is a top-level goal, the destructor won't run in a
timely manner since its reference count won't drop to zero.  So
release it explicitly.

Fixes #178.

backward compatibility).
