If we want to use this function/command internally, we don't want this
warning shown.

Paul Eggleton 8f8a9ef669 bitbake: tinfoil: pass datastore to server when expanding python references
If you're expanding a value that refers to the value of a variable in
python code, we need to ensure that the datastore that gets used to get
the value of that variable is the client-side datastore and not just the
part of it that's on the server side. For example, suppose you are in
client code doing the following:

d.setVar('HELLO', 'there')
result = d.expand('${@d.getVar("HELLO", True)}')

result should be "there" but if the client part wasn't taken into
account, it would be whatever value HELLO had in the server portion of
the datastore (if any).

Paul Eggleton f1f3a112a0 bitbake: tinfoil: implement server-side recipe parsing
It's not really practical for us to parse recipes on the client side, we
need to do it on the server because that's where we have the full python
environment (including any "pure" python functions defined in classes).
Thus, add some functions to tinfoil do this including a few shortcut
functions.

Paul Eggleton 7d5c9860de bitbake: tinfoil: rewrite as a wrapper around the UI
Rewrite tinfoil as a wrapper around the UI, instead of the earlier
approach of starting up just enough of cooker to do what we want. This
has several advantages:

* It now works when bitbake is memory-resident instead of failing with
  "ERROR: Only one copy of bitbake should be run against a build
  directory".

* We can now connect an actual UI, thus you get things like the recipe
  parsing / cache loading progress bar and parse error handling for free

* We can now handle events generated by the server if we wish to do so

* We can potentially extend this to do more stuff, e.g. actually running
  build operations - this needs to be made more practical before we can
  use it though (since you effectively have to become the UI yourself
  for this at the moment.)

The downside is that tinfoil no longer has direct access to cooker, the
global datastore, or the cache. To mitigate this I have extended
data_smart to provide remote access capability for the datastore, and
created "fake" cooker and cooker.recipecache / cooker.collection adapter
objects in order to avoid breaking too many tinfoil-using scripts that
might be out there (we've never officially documented tinfoil or
BitBake's internal code, but we can still make accommodations where
practical). I've at least gone far enough to support all of the
utilities that use tinfoil in OE-Core with some changes, but I know
there are scripts such as Chris Larson's "bb" out there that do make
other calls into BitBake code that I'm not currently providing access to
through the adapters.

Part of the fix for [YOCTO #5470].

Paul Eggleton 26aad57ece bitbake: tinfoil: add a parse_recipe_file function
Parsing a recipe is such a common task for tinfoil-using scripts, and is
a little awkward to do properly, so add an API function to do it. This
should also isolate scripts a little from future changes to the internal
code. The first user of this will be the OpenEmbedded layer index update
script.

Part of the fix for [YOCTO #10192].

Paul Eggleton 8f277fcf33 bitbake: tinfoil: add context manager functions
Since calling the shutdown() function is highly recommended, make
tinfoil objects a little easier to deal with by adding context manager
support - so you can do the following:

    with bb.tinfoil.Tinfoil() as tinfoil:
        tinfoil.prepare(True)
        ...

Richard Purdie 218b81acb6 bitbake: bitbake: Initial multi-config support
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.

Richard Purdie 4c2f28bf48 bitbake: cooker: properly fix bitbake.lock handling
If the PR server or indeed any other child process takes some time to
exit (which it sometimes does when saving its database), it can end up
holding bitbake.lock after the UI exits, which led to errors if you ran
bitbake commands successively - we saw this when running the PR server
oe-selftest tests in OE-Core. The recent attempt to fix this wasn't
quite right and ended up breaking memory resident bitbake. This time we
close the lock file when cooker shuts down (inside the UI process)
instead of unlocking it, and this is done in the cooker code rather than
the actual UI code so it doesn't matter which UI is in use. Additionally
we report that we're waiting for the lock to be released, using lsof or
fuser if available to list the processes with the lock open.

The 'magic' in the locking is due to all spawned subprocesses of bitbake
holding an open file descriptor to the bitbake.lock. It is automatically
unlocked when all those fds close the file (as all the processes terminate).
We close the UI copy of the lock explicitly, then close the server process
copy, any remaining open copy is therefore some proess exiting.

(The reproducer for the problem is to set PRSERV_HOST = "localhost:0"
and add a call to time.sleep(20) after self.server_close() in
lib/prserv/serv.py, then run "bitbake -p; bitbake -p" ).

Cleanup work done by Paul Eggleton <paul.eggleton@linux.intel.com>.

This reverts bitbake commit 69ecd15aece54753154950c55d7af42f85ad8606 and
e97a9f1528d77503b5c93e48e3de9933fbb9f3cd.

Richard Purdie ada930055d bitbake: tinfoil: Add shutdown method
One drawback to tinfoil is that once a cooker is created, it will hold
the cooker lock and stop any other bitbake execution against a directory.

Add a shutdown method to tinfoil, allowing other users to use
the build directory after the tinfoil usage is no longer needed.

Paul Eggleton 1894522f35 bitbake: tinfoil: add a means of enabling variable history tracking
Unfortunately it seems like the external use of the cooker
enableDataTracking() function broke at some point since the code that
reads it now runs within BBCooker's constructor. Since this now has to
be done early, add a parameter to Tinfoil's constructor to allow
enabling variable history tracking.

Fixes [YOCTO #6676].

Richard Purdie fa4b1fa257 bitbake: cooker/cookerdata: Improve configuration object handling
Originally it seemed like a good idea to keep the parameters around. Having
seen this in real life use, its incorrect, we should pull all the data we need
into the cooker's configuguration and then use this to build the datastore.

Being able to just build the datastore from the parameters seemed like a good
idea but having a dummy cooker configuration object is now looking like
the better option.

This also fixes failures in hob since the parseFiles command can call
into cooker directly now and reset the configuration prefiles and postfiles
at will, rather than the indirect calls before which were breaking the datastore
(e.g. BBPATH wasn't set).

The cleanup this allows in tinfoil illustrates how this change makes more sense.
