The colors specified for use with bitbake-diffsigs were adapted for a

To make it look good both with a dark or a light theme, it is better
to drop the background color. It is also better to leave out the color
altogether for the title and just use bold. Finally, dropping bold for
the red and green texts indicating removed/added values better matches

This patch adds the capability for tasks from different
multiconfigs to depend on one another.
These dependencies can be enabled using the following format:
task[mcdepends] = "multiconfig:FROM-MC:TO-MC:PN:task-to-depend-on"
For the sake of simplicity consider the following example:
Assuming we have set up multiconfig builds, one for qemux86 and one for
qemuarm, named x86 and arm respectively.
Adding the following line to an image recipe (core-image-sato):
do_image[mcdepends] = "multiconfig:x86:arm:core-image-minimal:do_rootfs"
Would state that core-image-sato:do_image from x86 will depend on
core-image-minimal:do_rootfs from arm so it can be executed.
This patch makes modifications to:
- cooker: To glue both multiconfigs in one place and make sure
the dependencies can be provided.
- taskdata: To parse and add a new kind of dependency (mcdepends) to
the taskdata object.
- runqueue: To differentiate tasks from different multiconfigs,
add the specified dependencies to the corresponding tasks, and
create a working runqueue that contains tasks from both multiconfigs.
- siggen: To avoid looking for tasks from different multiconfigs on
objects where they dont belong.
The taskdata objects are still not aware of the concept of multiconfig,
so each object doesnt know which multiconfig its building, hence why
the mcdepends are added to all taskdata objects equally (we really
dont expect many of these), but the actual dependencies are added only
to the required tasks by the runqueue.

Note: I elected to keep to one item in the returned list per change,

look at changes individually if needed. Thus I've added some handling to
bitbake-diffsigs to split the change into lines so that each line is

Bitbake can parse metadata in the cooker and in the worker during builds. If
the metadata isn't deterministic, it can change between these two parses and
this confuses things a lot. It turns out to be hard to debug these issues
currently.
This patch ensures the basehashes from the original parsing are passed into
the workers and that these are checked when reparsing for consistency. The user
is shown an error message if inconsistencies are found.
There is debug code in siggen.py (see the "Slow but can be useful for debugging
mismatched basehashes" commented code), we don't enable this by default due to
performance issues. If you run into this message, enable this code and you will
find "sigbasedata" files in tmp/stamps which should correspond to the hashes
shown in this error message. bitbake-diffsigs on the files should show which
variables are changing.

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.

In theory all the information to recalcuate the task signatures was written
into the siginfo/sigdata files. In reality, some of the information was
written into the filename.
Firstly this patch duplicates that info into the file itself just for easy
of use since its small.
Secondly, we abstract out the existing "calculate the checksum" code for
the taskhash, and add a function to calculate the bashhash based on the
informaiton within the file.
Finally, we call these functions when we're writing out the data to check
that the data we're writing is consistent. I've found a couple of places
it wasn't and its good to know about these in advance, rather than having
a siginfo/sigdata file which a given hash in its filename but a contents
which give a different result.
This should all combine to avoid a certain class of checksum bugs making
it into world, and identifying problems in advance.

Currently, if you reference a file url, its checksum is included in the
task hash, however if you change to a different file at a different
location, perhaps taking advantage of the FILESPATH functionality, the
system will not reparse the file in question and change its checksum to
match the new file.
To correctly handle this, the system not only needs to know if the
existing file still exists or not, but also check the existance
of every file it would have looked at when computing the original file.
We already do this in the bitbake parsing code for class inclusion. This
change uses the same technique to log the file list we looked at and
if files in these locations exist when they previously did not, to
invalidate and reparse the file.
Since data stored in the cache is flattened text, we have to use a string
form of the data and split on the ":" character which is ugly, but is
an internal detail we can improve later if a better method is found.
The cache version changes to trigger a reparse since the previous
cache data is now incompatible.
