Due to the worker split the ${DATE} and ${TIME} variables could end up
with different values for different workers.
E.g., a task like do_rootfs that is run within a fakeroot environment
had a slightly different view of the time than another task that was not
fakerooted which made it impossible to correctly refer to the image
generated by do_rootfs from the other task.

The existing backend server implementations were inefficient since they
were sleeping for the full length of the timeouts rather than being woken when
there was data ready for them. It was assumed they would wake and perhaps did
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
does mean we need to pass the file descriptors to wait on from the internals
who know which these file descriptors are but this is a logical improvement.
Tests of a pathaolgical load on the process server of ~420 rapid tasks
executed on a server with BB_NUMBER_THREAD=48 went from a wall clock
measurement of the overall command execution time of 75s to a much more
reasonable 24s.

Currently, tasks like fetchall are slightly broken since if a recipe
has specific [depends] which occur after do_fetch and add items not listed
in DEPENDS and RDEPENDS, they are not caught by recrdeptask. We've gone
around in circles on this issue (e.g
http://git.yoctoproject.org/cgit.cgi/poky/commit/bitbake/lib/bb/runqueue.py?id=5fa6036d49ed7befe6ad50ec95c61a50aec48195
) and in many cases the behaviour of recrdepends is correct but tasks like
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.

If a setscene task has a hard dependency on a task like pseudo-native, its
expected that the setscene task will not run unless the dependency is met.
This adds code to ensure that is the case, otherwise a bug would show up
with a usecase like:
bitbake gnome-common
bitbake pseudo-native -c cleansstate
bitbake gnome-common -c clean

With the double wrapper script environment, we'd not see issues like
this as it would be masked. The problem theoretically affects code like

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.

When the setscene code was originally written it was thought that we'd
allow "partial" coverage. For example, if we just want to build the target
"bash:do_populate_sysroot" and its available from sstate, it makes no sense
to install gcc-cross's sstate package as its simply not needed.
Due to various other issues in the codebase, this functionality was
disabled/removed to allow the setscene code and sstate to stabilise and allow
us to concentrate on other problems.
The time has now come to enable "partial" coverage. There are two major changes
in this patch:
a) Creation of an unskippable list. This lists direct dependencies of
build targets and hence things that cannot be skipped.
b) Addition of a handler which looks at a given setscene target and what depends
on it and then decides whether its necessary.

There was some odd behaviour if some task was run from setcene whilst there were
existing valid stamps for a depepdency. For example, do_populate_sysroot might
be installed at setscene time but if there were other tasks not installed from
setscene such as do_populate_lic which depend on do_configure, the setsceneverify
function would think that do_configure needed to be rerun and would hence void the
do_populate_sysroot and force that to rerun too.
The setsceneverify function needs to know which tasks are going to be rerun, not just
what the overall task list is and what setscene functions have run. This patch adds
that information and maintains backwards compatibility in a slightly ugly but effective
way. The metadata needs updating to take advantage of this change.

In some cases we want to pull in DEPENDS and RDEPENDS of recrdeptask
dependencies but we need a way to trigger or avoid this behaviour
depending on context. The logical syntax to trigger such behaviour
would be a self referencing recrdeptask:
do_a[recrdeptask] = "do_a do_b"
The dependency chains already recurse this kind of expression correctly, the
missing piece is to avoid any circular reference errors. Since the dependencies
have already been recursively resolved, simply removing any recrdeptask
references is enough to break the circular references.
This patch therefore removes any circular references using the set
difference_update() operator. There will be metadata tweaks required to
add any references needed to the extra taskname.

Currently, recrdepends is extremely greedy. For example:
do_foo[rdepends] = "somedep:sometask"
addtask foo
which adds foo with *no* dependencies, will suddenly start appearing
as a dependency in every task which uses recrdepends. So far this has
been mildy annoying but we now have use cases where this makes no sense
at all.
This reworks the recrdepends code to avoid this problem. To do this we
can no longer collapse things into lists just based on file ID. The problem
is this code is extremely performance sensitive. The "preparing runqueue"
phase spends a lot of time in these recursive dependency calculations so any
change here could negatively impact the user experience.
As such, this code has been carefully tested on convoluted dependency trees
with operations like "time bitbake world -g". The net result of this change
and the preceeding changes combined is a net speed up of these operations in
all cases measured.
Tests were made comparing "bitbake world -g" task-depends.dot before and after
this patch. There *are* differences for example -nativesdk do_build dependencies
on -native recipes are no longer present. All removed dependencies appear to
be sensible improvements to the system. The "rdepends" cross contamination
issue above is also fixed.

This new command line option forces the specified task and all dependent
tasks up to the default task to re-run. This means that the following
single step:
bitbake -C compile somerecipe
is equivalent to the following two steps (with the recent change to -f):
bitbake -c compile -f somerecipe
bitbake somerecipe
Note that to work this option needs full hashing enabled (i.e.
BB_SIGNATURE_HANDLER must be set to a signature handler that inherits
from BasicHash). If this is not the case, -C effectively does nothing.
Based on a previous implementation of this option by Jason Wessel
<jason.wessel@windriver.com>.

If -f is specified, force dependent tasks to be re-run next time. This
works by changing the force behaviour so that instead of deleting the
task's stamp, we write a "taint" file into the stamps directory, which
will alter the taskhash randomly and thus trigger the task to re-run
next time we evaluate whether or not that should be done as well as
influencing the taskhashes of any dependent tasks so that they are
similarly re-triggered. As a bonus because we write this file as
<stamp file name>.taskname.taint, the existing code which deletes the
stamp files in OE's do_clean will already handle removing it.
This means you can now do the following:
bitbake somepackage
[ change the source code in the package's WORKDIR ]
bitbake -c compile -f somepackage
bitbake somepackage
and the result will be that all of the tasks that depend on do_compile
(do_install, do_package, etc.) will be re-run in the last step.
Note that to operate in the manner described above you need full hashing
enabled (i.e. BB_SIGNATURE_HANDLER must be set to a signature handler
that inherits from BasicHash). If this is not the case, -f will just
delete the stamp for the specified task as it did before.
This fix is required for [YOCTO #2615] and [YOCTO #2256].

Currently the code checking whether stamps are valid only traverses one step
of the dependency graph. This works fine in the normal cases where we've already
validated dependencies but for the setscene code, it doesn't work well. A typical
problem usecase is something like:
bitbake gcc-cross -c unpack -f
bitbake gcc-cross
which will ignore any sstate files already cached which could be used to speed
up the gcc-cross build. This becomes particularly problematic with multiple gcc
builds where only one should rebuild yet they all do.
This patch teaches the stamp code to be able to recurse within a given fn
which gives the behaviour people would expect from the code and allows
bitbake to make better use of prebuild sstate objects.
