Given these assignments:
TEST="a b c d"
TEST_remove = "b d"
TEST evaluates to "a c". However, if the _remove override is given as a
variable:
TEST="a b c d"
FOO = "b d"
TEST_remove = "${FOO}
TEST evaluates to "a b c d", because when FOO is expanded it isn't split into a
list.
Solve this by splitting all members of removeactive once they've been expanded.

These only have one instance created which means your subsequent datastores
can contain echos of previous ones. Obviously this is not the behaviour
we want/expect. It doesn't affect bitbake too badly as we only have one
datastore, it does massively potentially break our selftests though.

In the depths of time we were rather confused about naming. bb files

leaves the other around for now. We can therefore start removing

If you try:
Y = ""
Y_remove = "X"
in OE-Core, bitbake will crash with a KeyError during expansion. The reason
is that no expansion of the empty value is attempted but removal from is it
and hence no varparse data is present for it in the expand_cache.
If the value is empty, there is nothing to remove so the best fix is simply
not to check for None but check it has any value.
Also add a test for this error so it doesn't get reintroduced.

Unfortunately we've been neglecting to pay the correct tributes to the
cookie monster and hence the datastore is malfunctioning.
Currently tributes are only paid on the last part of a variable after
the last "_" character. We need to split by *all* "_" characters since
an override may contain the character.
This fixes the code so the correct number of tributes are made. Paradoxically
parsing appears to be faster after this change.

The previous "contains" changes caused a ~3% parsing speed impact.
Looking at the cause of those changes was interesting:
* Use of defaultdict was slower than just checking for missing entries
and setting them when needed.
* Even the "import collections" adversely affects parsing speed
* There was a missing intern function for the contains cache data
* Setting up a log object for each variable has noticeable overhead
due to the changes in the code paths uses, we can avoid this.
* We can call getVarFlag on "_content" directly within VariableParse
for a noticeable speed gain since its a seriously hot code path.
This patch therefore tweaks the code based on the above observations to
get some of the speed back.

One of the current frustrations with the sstate checksums is that
code like base_contains('X', 'y',...) adds a full dependency on X
and varies depend even on whitespace changes in X.
This patch adds special handling of the contains functions to expand
the first parameter and check for the flag specified by the second
parameter (assuming its a string).
The result is then appended to the value of the variable with a "Set"
or "Unset" status. If the flag is added/removed, the stored variable
value changes and hence the checksum changes. No dependency on X
is added so it is free to change with regard to other flags or
whitespace.
This code is far from ideal, ideally we'd have properly typed variables
however it fixes a major annoyance of the current checksums and
is of enough value its worth adding in a stopgap solution. It shouldn't
significantly restrict any propely typed variable implementation in
future.

There are long standing complaints about the fact its very difficult
to remove a portion of a variable. The immediate request is for a -=
and =- operator. The trouble is that += and =+ are "immediate"
operators and are applied straight away. Most people would expect
-= and =- to be deferred to have the effect most people desire and
therefore implementing -= and =- would just make the situation more
confusing.
This deferred operation is much more similar to the override syntax
which happens at data store finalisation. The _remove operator is
therefore in keeping with the _append and _prepend operations.
This code is loosely based on a patch from Peter Seebach although it
has been rewritten to be simpler, more efficient and avoid some
potential bugs.
The code currently only works on space delimited variables, which
are by far the most commom type. If bitbake is ehanced to support
types natively in future, we can adjust this code to adapt to that.

Currently if the flags set against a variable in the base data store
change, it doesn't automatically trigger a reparse when it really
should. For example with the blacklist class setting:
PNBLACKLIST[qemu] = "bar"
PNBLACKLIST[bash] = "foo"
will not trigger a reparse if only one entry is changed and a
blacklisted recipe can still be built.
I did consider using BB_SIGNATURE_EXCLUDE_FLAGS in here however it
doesn't make sense, we want to trigger a reparse when any of the
flags change too (which is different to the sstate signatures which
we wouldn't want to change in those cases).

This patch adds tracking of the history of variable assignments.
The changes are predominantly localized to data_smart.py and
parse/ast.py. cooker.py and data.py are altered to display the
recorded data, and turn tracking on for the bitbake -e case.
The data.py update_data() function warns DataSmart.finalize()
to report the caller one further back up the tree.
In general, d.setVar() does what it used to do. Optionally,
arguments describing an operation may be appended; if none
are present, the operation is implicitly ignored. If it's
not ignored, it will attempt to infer missing information
(name of variable, value assigned, file and line) by examining
the traceback. This slightly elaborate process eliminates a
category of problems in which the 'var' member of the keyword
arguments dict is set, and a positional argument corresponding
to 'var' is also set. It also makes calling much simpler for
the common cases.
The resulting output gives you a pretty good picture of what
values got set, and how they got set.
RP Modifications:
a) Split from IncludeHistory to separate VariableHistory
b) Add dedicated copy function instead of deepcopy
c) Use COW for variables dict
d) Remove 'value' loginfo value and just use 'details'
e) Desensitise code for calling order (set 'op' before/after
infer_caller_details was error prone)

values previously
h) Standardise infer_caller_details to be triggered from .record()
where at all possible to reduce overhead in non-enabled cases
i) Rename variable parameter names to match inference code
j) Add VariableHistory emit() function to match IncludeHistory
k) Fix handling of appendVar, prependVar and matching flag ops

This code adds inclusion history to bitbake -e output, showing
which files were included, in what order. This doesn't completely
resolve timing questions, because it doesn't show you which lines
of a file were processed before or after a given include, but it
does let you figure out what the path was by which a particular
file ended up in your build at all.
How it works: data_smart acquires a .history member, which is an
IncludeHistory; this represents the inclusion of a file and all its
inclusions, recursively. It provides methods for including files,
for finishing inclusion (done as an __exit__), and for
dumping the whole tree.
The parser is modified to run includes inside a with() to push
and pop the include filename.

a) Split Include and Variable tracking

If you d.delVar(), you expect the variable to be gone. Even empty
variables continue to exist in the datastore and are still user visible
unfortunately. The COW siutation means you can't just remove it
since it might unmask a variable from an inner copy.
This patch therefore stops empty variables from appearing in key lists
exposed to the external world making empty variables an internal
implementation detail only.

Since we're going to creat the seen set() anyway, we might as well use
it directly. If we don't do this, we see thousands of function calls
with associated overhead on profiles.

Currently if you do:
OVERRIDES = "z"
DEPENDS_prepend = "a "
DEPENDS = "b"
DEPENDS_z = "c"
d.update_data()
d.getVar("DEPENDS")
gives "a c"
d.update_data()
d.getVar("DEPENDS")
then gives "c"
This patch changes the behaviour such that at the time bitbake expands the DEPENDS_z
override, it removes "DEPENDS_z" from the data store. In the above example this would
mean that it wouldn't matter how often you call d.update_data(), you'd always get
"a c" back.
See the bitbake-devel mailing list for further discussion and analysis of the
potential impact of this change.

If expanding a variable triggers an exception the caller currently has no
way to supress the error message or otherwise handle the siutation. An
example of where this is a problem is "bitbake -e" showing tracebacks and
errors for variables like SRCPV in OE/Poky.
Secondly in a chained expansion fails, log mesages are recorded for
every step of the expansion, not just the innermost error which is
where the real failure occured.
To fix this we introduce a new exception ExpansionError which callers
can handle as appropriate.

Currently, if a variable has been set with ??= and the code looks it up
before the data finalisation phase, no value is found. This is causes
serious problems for anonymous python functions which manipulate data, or
for the fetcher revision handling code where revisions can be set with
??=.
There is also a significant performance implication for processing lazy
assignment in finalise.
Moving the check for a default value into getVarFlag addresses both
the timing issue and the performace. This change gives a 7% real time
performance improvement to parsing the Poky metadata. The cost of the
check at this point is minimal since we have all the data flags available.
This should also fix Yocto bug 752.

This logger provides:
- 'debug' method which accepts a debug level
- 'plain' method which bypasses log formatting
- 'verbose' method which is more detail than info, but less than debug

Add a parameter to getVarFlag() to auto-expand the value of the flag. This
makes getVarFlag() more consistent with getVar(), and allows expansion of
vardeps and vardepsexclude (which has been done in this commit).

Where a variable name consisted of an append/prepend combined with an override
and there was also an append/prepend to the variable, the override could be lost
if the override was not in OVERRIDES.
For example:
FOO = "A"
FOO_append = "B"
FOO_append_virtclass-native = "C"
could result in "AB" even though virtclass-native was in OVERRIDES.
With this patch applied, the result is "ABC" as would be expected.
The problem was the deletion of the _append/_prepend flag was happening
if *any* append/prepend was procesed, the result should really be that
it should contain any unprocessed append/prepend.
Kevin Tian deserves credit for looking into this and working out the
problem here.

This commit is derived from Chris Larson's checksum work, turned into a
standalone piece of code for parsing python and shell functions.
The deindent code has been replaced with code to work around indentation
for speed. The original NodeVisitor in the ast was replaced with a faster
class walk call.

The root cause is, I was testing the use of renameVar() from finalize, in
order to get flags copied over when an override is applied, but renameVar
removes the original, whereas the old code did not do so. Going back to the
old method, will revisit the override/flags later on.

- Use a single dictionary for the context, both global & local, since for some
reason it chokes wanting a global "d" rather than a local in the metadata.
- First compile the string into a code object before running eval, so we can
include the variable name in an evaluation error.

dict objects provide an __iter__ method for the iteration which gives you the
keys, so calling keys directly is unnecessary, and isn't really a best
practice. The only time you really need to call the keys is if there's a
danger of the dict changing out from underneith you, either due to external
forces or due to modification of the iterable in the loop. Iterations over
os.environ are apparently subject to such changes, so they must continue to
use keys().
As an aside, also switches a couple spots to using sorted() rather than
creating a temporary list with keys() and sorting that.

The "Z" would be lost if X_${Y} was unset. This was due to a bug in the renameVar
