Use of waitpid on the worker processes is a bad idea since it conflicts
directly with subprocess internals. Instead use the poll() method
and returncode to determine if the process has exitted, if it has,
we can shut down the system.
This should resolve the hangs once and for all, famous last words.

We're running into processes using 100% cpu. It appears theses are locked in
a subprocess.poll() type loop where the process has exited but the code is
looping as its not handling the ECHILD error.
http://bugs.python.org/issue14396http://bugs.python.org/issue15756
This is likely due to one or both of the above bugs. The question is what actually
grabbed the child exit code as it wasn't this code. Its likely there is therefore
some other code racing and taking that code, it may be some kind of race like:
http://hg.python.org/cpython/rev/767420808a62/
where the fix effectively catches the childs codes in a different part of the system.
We could try and get everyone onto python 2.7.4 where the above bugs are fixed however
for now its safer to admit defeat and go back to polling explictly for our worker exit
codes.

There are several problems. Firstly, a return value of "None" can mean
there is a C signal handler installed so we need to better handle that
case. signal.SIG_DFL is 0 which equates to false so we also need to
handle that by testing explicitly for None.
Finally, the signal handler *must* call waitpid on all child processes
else it will just get called repeatedly, leading to the hanging behaviour
we've been seeing. The solution is to only error for the worker children,
we warn about any other stray children which we'll have to figure out the
sources of in due course.
Hopefully this patch gets things working again properly though.

If you specify multiple targets on bitbake's commandline and some of them are
setscene tasks which are "masked" by other tasks they may not get run.
For example <image>:do_rootfs <kernel>:do_populate_sysroot
the rootfs tasks "masks" the populate_sysroot task so bitbake would currently
decide not to run it. In this case, we do really want it to be run.
The fix is not to skip anything which has been given as an explict target.

Commit c54e738e2b5dc0d8e6fd8e93b284ed96e7a83051 added in the idea of hard dependencies
such as the case a setscene has a hard dependency on pseudo-native and that
dependency wasn't available from sstate for some reason.
Unfortunately the implementation was a bit too enthusiastic, causing rebuilds
of things when it wasn't necessary. A test case was:
bitbake quilt-native
bitbake quilt-native -c clean
bitbake <some-image>
and then you'd watch quilt-native get rebuilt for no good reason.
The clue to the problem is in the for loop where it never depends on
the item being iterated over.
The fix is to include the exact list of hard dependencies rather than
guessing. With these changes, the use case above works, the one in
the original commit also works.
This patch also adds in or cleans up various pieces of logging to
allow issues like this to be more easily debugged in future.

This unlikely looking function was found to be eating a lot of CPU time
since it gets called once per trip through the idle loop if we're not
running a maximum number of processes. This was particularly true in
world builds of 13,000 tasks.
Calling the computation code is pretty pointless because until some
other task finishes nothing is going to become available to build.
We can know when things become available so this patch teaches the
scheduler this knowledge.
It also:
* skips any coputation when nothing can be built
* if there is only one available item to build, ignore the priority map
* precomputes the stamp filenames, rather than doing it every time
* saves the length of the array rather than calculating it each time
(the extra function overhead is significant)
Timing wise, initially, 5000 iterations through here was 20s, with
the patch 200000 calls takes the same time. The end result is that
builds get up and running faster.

We have do_bundle_initramfs which is a task inserted after compile and
before build. It is not covered by sstate.
If we run a build with a valid sstate cache present, the setsceneverify
function realises it will rerun the do_compile step (due to the
bundle_initramfs task) and hence marks do_populate_sysroot to rerun.
do_install, a dependency of do_populate_sysroot is left as marked as
covered by sstate.
What we need to do is traverse the dependency tree for any setsceneverify
invalided task and ensure any dependencies are also invalidated. We can
stop at any point we reach another setscene task though.
This means the do_populate_sysroot task has the data from do_install
available and doesn't crash.

The existing backend server implementations were inefficient since they

when we forked processes directory but that is no longer the case.
This updates both the process and xmlrpc backends to wait using select(). This

who know which these file descriptors are but this is a logical improvement.

Currently, tasks like fetchall are slightly broken since if a recipe
has specific [depends] which occur after do_fetch and add items not listed

around in circles on this issue (e.g

fetchall need the other behaviour.
To address this we add a recideptask flag which can be used in conjuction
with the recrdeptask flag to specify which task to to the inspection upon.
This means entries like do_rootfs[depends] which have do_fetch tasks are
caught and run.
I'm not 100% happy with needing another flag but I don't see any rational
way to get the correct behaviour in all cases without it.

This is a pretty fundamental change to the way bitbake operates. It
splits out the task execution part of runqueue into a completely
separately exec'd process called bitbake-worker.
This means that the separate process has to build its own datastore and
that configuration needs to be passed from the cooker over to the
bitbake worker process.
Known issues:
* Hob is broken with this patch since it writes to the configuration
and that configuration isn't preserved in bitbake-worker.
* We create a worker for setscene, then a new worker for the main task
execution. This is wasteful but shouldn't be hard to fix.
* We probably send too much data over to bitbake-worker, need to
see if we can streamline it.
These are issues which will be followed up in subsequent patches.
This patch sets the groundwork for the removal of the double bitbake
execution for psuedo which will be in a follow on patch.
