Hooking the disk monitor into the regular heatbeat event instead
of the runqueue solves two problems:
- When there is just one long running task which fills up the disk,
the previous approach did not notice that until after the completion
of the task because _execute_runqueue() only gets called on task
state changes. As a result, aborting a build did not work in this
case.
- When there are many short-lived tasks, disk space was getting
checked very frequently. When the storage that is getting checked
is on an NFS server, that can lead to noticable traffic to the
server.

Some task id manipulations were suboptimal:
* taskfn_fromtid and fn_from_tid were effectively the same function
* many calls to split_tid(), then taskfn_fromtid()
* taskfn_fromtid() called split_tid() internally
This patch adds split_tid_mcfn() to replace split_tid() and returns the
"taskfn" variant being used in many places. We update all core calls
to the new function and ignore the return values we don't need since the
function call overhead of the split_tid wrapper is higher than ignoring
a return value.
The one remaining standalone use of taskfn_fromtid is replaced with
fn_from_tid. I couldn't see any external usage so it was dropped.
There is external usage of split_tid so a wrapper remains for it.
Combined together these changes should improve some of the runqueue task
manipulation performance.

If you "bitbake glibc-locale" then delete the libpcre-native sstate
and "bitbake glibc-locale -C package_write_rpm", it will fail with
rpmbuild missing the libprce library.
The reason is that libpcre-native fails to install from sstate (since
it isn't present) but doesn't get built and hence rpm-native tries to
run without its dependencies.
The simplest fix is not to add "covered" tasks which have failed to
install sstate. I can't help feeling there is more to this issue but
this does fix the current problem and shouldn't have adverse affects.
It is an unusual situation to have missing dependencies in sstate since
they're usually all present or not at all.
I've taken the opportunity to remove some old cruft from when we had
numeric task ids, the code can be simpler now.

We can't execute the same task for the same package_arch multiple
times as the current setup has conflicting directories. Since
these would usually have the same stamp/hash, we want to execute in
sequence rather than in parallel, so for the purposes of task execution,
don't consider the "extra-info" on the stamp files. We need to add
a parameter to the stamp function to achieve this.
This avoids multiple update-rc.d populate_sysroot tasks executing in
parallel and breaking multiconfig builds.

This patch adds the notion of supporting multiple configurations within
a single build. To enable it, set a line in local.conf like:
BBMULTICONFIG = "configA configB configC"
This would tell bitbake that before it parses the base configuration,
it should load conf/configA.conf and so on for each different
configuration. These would contain lines like:
MACHINE = "A"
or other variables which can be set which can be built in the same
build directory (or change TMPDIR not to conflict).
One downside I've already discovered is that if we want to inherit this
file right at the start of parsing, the only place you can put the
configurations is in "cwd", since BBPATH isn't constructed until the
layers are parsed and therefore using it as a preconf file isn't
possible unless its located there.
Execution of these targets takes the form "bitbake
multiconfig:configA:core-image-minimal core-image-sato" so similar to
our virtclass approach for native/nativesdk/multilib using BBCLASSEXTEND.
Implementation wise, the implication is that instead of tasks being
uniquely referenced with "recipename/fn:task" it now needs to be
"configuration:recipename:task".
We already started using "virtual" filenames for recipes when we
implemented BBCLASSEXTEND and this patch adds a new prefix to
these, "multiconfig:<configname>:" and hence avoid changes to a large
part of the codebase thanks to this. databuilder has an internal array
of data stores and uses the right one depending on the supplied virtual
filename.
That trick allows us to use the existing parsing code including the
multithreading mostly unchanged as well as most of the cache code.
For recipecache, we end up with a dict of these accessed by
multiconfig (mc). taskdata and runqueue can only cope with one recipecache
so for taskdata, we pass in each recipecache and have it compute the result
and end up with an array of taskdatas. We can only have one runqueue so there
extensive changes there.
This initial implementation has some drawbacks:
a) There are no inter-multi-configuration dependencies as yet
b) There are no sstate optimisations. This means if the build uses the
same object twice in say two different TMPDIRs, it will either load from
an existing sstate cache at the start or build it twice. We can then in
due course look at ways in which it would only build it once and then
reuse it. This will likely need significant changes to the way sstate
currently works to make that possible.

When "Preparing RunQueue" shows up you can expect to wait up to 30
seconds while it works - which is a bit long to leave the user waiting
without any kind of output. Since the work being carried out during this
time is divided into stages such that it's practical to determine
internally how it's progressing, replace the message with a progress
bar.
Actually what happens during this time is two major steps rather than
just one - the runqueue preparation itself, followed by the
initialisation prior to running setscene tasks. I elected to have the
progress bar cover both as one (there doesn't appear to be much point in
doing otherwise from a user perspective). I did however describe it as
"initialising tasks".

Add the ability to enter a mode where only a specified whitelist of
tasks can be executed outright; everything else must be successfully
provided in the form of a setscene task (or covered by a setscene task).
Any setscene failure outside of the whitelist will cause the build to
fail immediately instead of running the real task, and any real tasks
that would execute outside of the whitelist cause an immediate build
failure when it comes to executing the runqueue as well.
The mode is enabled by setting BB_SETSCENE_ENFORCE="1", and the
whitelist is specified through BB_SETSCENE_ENFORCE_WHITELIST, consisting
of pn:taskname pairs. A single % character can be substituted for the pn
value to match any target explicitly specified on the bitbake command
line. Wildcards * and ? can also be used as per standard unix file name
matching for both pn and taskname.

I'm not sure what possesed me when I wrote this code originally but its
indirection of everyting to use numeric IDs and position dependent lists
is horrific. Given the way python internals work, its completely and
utterly pointless from performance perspective. It also makes the code
hard to understand and debug since any numeric ID has to be translated
into something human readable.
The hard part is that the IDs are infectous and spread from taskdata
into runqueue and even partly into cooker for the dependency graph
processing. The only real way to deal with this is to convert everything
to use a more sane data structure.
This patch:
* Uses "<fn>:<taskname>" as the ID for tasks rather than a number
* Changes to dict() based structures rather than position dependent lists
* Drops the build name, runtime name and filename ID indexes
On the most part there shouldn't be user visible changes. Sadly we did
leak datastructures to the setscene verify function which has to be
rewritten. To handle this, the variable name used to specifiy the version
changes from BB_SETSCENE_VERIFY_FUNCTION to BB_SETSCENE_VERIFY_FUNCTION2
allowing multiple versions of bitbake to work with suitably written
metadata. Anyone with custom schedulers may also need to change them.
I believe the benefits in code readability and easier debugging far
outweigh those issues though. It also means we have a saner codebase
to add multiconfig support on top of.
During development, I did have some of the original code coexisting with
the new data stores to allow comparision of the data and check it was
working correcty, particuarly for taskdata. I have also compared
task-depends.dot files before and after the change. There should be no
functionality changes in this patch, its purely a data structure change
and that is visible in the patch.

The data included in the event is useful for implementing a pre-build
check that warns about unexpected components, for example because of
an incorrect configuration or changed dependencies.
Such a check can be done in a .bbclass that gets inherited
globally. But in contrast to a UI, such a class cannot request that
the event shall be emitted, and thus the event has to be emitted
whether there is a consumer or not.
This was done conditionally earlier out of concerns about the
performance impact. But now events are handled more efficiently, so
that concern no longer seems valid: in some simple testing (admittedly
on a fast build workstation), the two lines (generating the data and
emitting the event with it) only took about 0.05 seconds (measured
with timeit). That was for a build with roughly 500 recipes (from
pn-buildlist aka depgraph['pn']), triggered via the command line. That
was even with a consumer of the data active and doing some work, so it
should be even faster when there is no consumer.

When multiple recipes which both provide something are being built, bitbake
informs us that most likely one of them provides something the other doesn't,
which is usually correct, but unfortunately it's rather painful to figure out
exactly what that is.
This patch dumps two sets of information, one is the provides information for
each recipe, filtered so only common components are removed. The other is a list
of dependees on the recipe, since sometimes this can easily identify why something
is being built.
Its not straightforward for bitbake to obtain the information but since the
warning/error code path isn't the normal one, we can afford to go through some
less than optimal processing to aid debugging.
Also provide the same information even if we're showing a warning since its still
useful.

This reverts commit b22592af81.
That commit isn't entirely clear about why this change is needed but
I do have a usecase where this breaks things. If for example you run
"bitbake X -c packagedata" and that packagedata is in sstate, you'd
expect this to work.
If sstate doesn't contain a do_populate_sysroot for a dependency, you
would still expect the command above to succeed and you would not
expect
it to rebuild that dependency. With the current code, this isn't what
happens. The code finds the sstate for do_populate_sysroot missing,
this makes the task "uncovered" and this in turn makes it unskippable.
The example I found with this was avahi-ui, where it would trigger
a build of libdaemon to obtain its populate_sysroot.
Since this behaviour seems completely incorrect, revert the older patch
and we'll address any issues that crop up as a result.

Debugging suggests that setscene tasks are being a little greedy about their
dependencies, for example, lsof is insisting that gcc-runtime's do_package
is installed. If it isn't, its requiring gcc to rebuild.
If gcc-runtime do_package_write_xxx and do_packagedata is available, there
is no reason do_package should be needed.
The reason this is happening appears to be from the batching up of task
dependencies code, rather than setscene tasks stopping when passing over
a setscene task, they were being carried forward. This patch fixes it
so the data is 'zeroed' when passing over a setscene task boundary,
which gives the dependency graph that is expected.
After this patch, lsof will rebuild quite happily without
gcc-runtime:do_package being present, as expected. This should lead to
less dependencies being installed for builds from sstate and generally
better performance in general.

Currently we get no profiling oversight into either the main bitbake worker
process, or the overall parsing before task execution. This adds in extra
profiling hooks so we can truly capture all parts of bitbake's execution
into the profile data.
To do this we modify the 'magic' value passed to bitbake-worker to trigger
the profiling, before the configuration data is sent over to the worker.

Currently, if you have hard dependencies between setscene tasks (like avahi on
base-passwd through useradd.bbclass), other dependencies may not be installed
even if these exist in sstate. For example, avahi -> expat -> pigz-native
(and avahi -> base-passwd) yet if you cleansstate base-passwd:
bitbake gzip-native:do_clean avahi:do_clean expat:do_clean pigz-native:do_clean base-passwd:do_cleansstate
bitbake avahi | tee
you will currently see pigz-native being rebuilt even though it was in
sstate. The fix for this is to continue to iterate dependency chains
around hard blocked dependencies as per this patch.
After this patch is applied, you will see pigz-native installed from sstate.

When looking at a list of tasks, do_patch and do_unpack were being
given equal priority when one clearly depends on another. The
reason for this was the default task weights of 0 being to tasks.
This is therefore changed to 1 to allow correct weighting of dependencies
which means the scheduler has better information available to it about
tasks.
Weight endpoints differently (10) for clearer debugging of priorities.

The first part of the sstate code checks en-mass whether given checksums
are available. The next part of the code then either triggers those
setscene tasks either running them or skipping them if they've been
covered by others.
The problems was that this second part would always skip a task if it
was unavailable in the first part, even if it would have otherwise been
covered by other tasks.
This mean the mere presence of an artefact (or lack of presence) could
cause a different build failure.
The issue reproduces if you run a build and populate an sstate feed, then
run a second build off that feed, then run a third build off the sstate
feed of the second build (which is reduced in size).
The fix is rather than immediately skipping tasks if the checksum is
unavailable, create a list of missing tasks, then, if that task cannot
be covered by others we can skip it later. The deferral makes the
behaviour the same even when the cache is "incomplete".

We're running into processes using 100% cpu. It appears theses are locked in

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

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.

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
bitbake gnome-common
With the double wrapper script environment, we'd not see issues like
this as it would be masked. The problem theoretically affects code like
useradd too as well as anything using a sstate postinstall.

With the change to bitbake-worker we need to ensure the workers know
how to contact the PR service, the magic 0 port and singleton is
no longer enough.

We're going to need a fakeroot/pseudo version of the worker so
abstract the code to start the worker process.

The worker was being executed by each execution queue so would get
constructed twice for each build. This is wasteful so move execution
to the main runqueue so we only have to start the worker once.
