We've reports of hash collision with codeparser. Looking at the way collision
problems occur with md5 and the way our function templating works, I can believe
we may run into issues.
This patch therefore switches to sha256.
Performance wise, parse time could appear to rise by 4s in 374s
Before:
384329 in 2.966s (md5)
After:
349743 in 2.340s (sha256)
34723 in 1.245s (md5)
since we still have md5 used elsewhere in the code, something we should look at
next (using sha256 everywhere is around 5.3s in total)
Unfortunately this does nearly double the size of the codeparser cache file
due to the hash size change.

* base_conditional was already removed from oe-core:
http://git.openembedded.org/openembedded-core/commit/?id=0391fcad9103abca0796a068f957d0df63ab4776
after the usage was migrated to oe.utils.conditional:
http://git.openembedded.org/openembedded-core/commit/?id=c97acbd034532895ce57c6717ed1b3ccc7900b0d
so we can handle just ".conditional" version
* add 1st parameter to variable dependencies, that way when you use
FOO = "${@oe.utils.conditional('VAR', 'VALUE', 'true', 'false')"
FOO variable will have dependency on VAR variable and you don't need
to add FOO[vardeps] += "VAR" manually every time you use
oe.utils.conditional
* this is similar to contains tracking from:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=3890
http://git.openembedded.org/bitbake/commit/?id=ed2d0a22a80299de0cfd377999950cf4b26c512e
http://git.openembedded.org/bitbake/commit/?id=0b9d117631ce909312d53b93289e61defc6be01c
but conditional is simpler, we don't need to handle the first
parameter as a set

Ensure we handle bb.utils.contains_any() as separate items, rather than
how we handle contains() where every item must be in the list.
Additionally, enable handling bb.utils.filter() which for the purposes
of looking at dependencies is the same as contains_any().
Additionally bump the codeparser cache and recipe cache versions to
invalidate the user's existing caches (ensuring that the changes take
effect and avoiding "taskhash mismatch" errors respectively).

BufferedLogger was sending log records to the target logger without
checking if the logger is enabled for the level of the record - and
handle() doesn't check this either (it's normally checked earlier when
the relevant log function is called e.g. logger.debug()), leading for
example to debug messages from codeparser getting printed when the log
level for the main BitBake logger was set to logging.WARNING.

For shell constructs like
echo hello & wait $!
the process_tokens() method ended up with a situation where "token"
in the "name, value = token" assignment was a list of tuples
and not the expected tuple, causing the assignment to fail.
There were already two for loops (one in _parse_shell(), one in
process_tokens()) which iterated over token lists. Apparently the
actual nesting can also be deeper.
Now there is just one such loop in process_token_list() which calls
itself recursively when it detects that a list entry is another list.
As a side effect (improvement?!) of the loop removal in
_parse_shell(), the local function definitions in process_tokens() get
executed less often.

which means we need to use hashlib.md5 to get consistent values for
the codeparser cache under python 3. Prior to this, the codeparser

Currently bitbake doesn't parse into data.expand() expressions,
relying on high level expansion of python code to handle this.
One of the tests does however test this works.
We don't really want to be doing string expansion on python code,
so specifically parse into expand() function calls so that when
the high level behaviour is tweaked, the self tests continue to
pass and that we do continue to handle expand() function calls as
best we can.

Currently, if there is something like a python indentation error in a
python function, the linenumbers and even file aren't reported correctly.
This allows lineno and filename parameters to be passed in to correct this.
The lack of a lineno parameter to python's compile() function is worked
around by using empty linefeeds. Ugly, but effective and with minimal
performance overhead.

It turns out the codeparser cache is the bottleneck I've been observing when running
bitbake commands, particularly as it grows. There are some things we can do about
this:
* We were processing the cache with "intern()" at save time. Its actually much
more memory efficient to do this at creation time.
* Use hashable objects such as frozenset rather than set so that we can
compare objects
* De-duplicate the cache objects, link duplicates to the same object saving
memory and disk usage and improving speed
* Using custom setstate/getstate to avoid the overhead of object attribute names
in the cache file
To make this work, a global cache was needed for the list of set objects as
this was the only way I could find to get the data in at setstate object creation
time :(.
Parsing shows a modest improvement with these changes, cache load time is
significantly better, cache save time is reduced since there is now no need
to reprocess the data and cache is much smaller.
We can drop the compress_keys() code and internSet code from the shared cache
core since its no longer used and replaced by codeparser specific pieces.

Currently if you do localdata.getVar, the code parser simply ignores
the references. Change the code to use endswith() to catch more of the
references. These names are probably unique enough to get away with this.

This includes contains_any in the special handling code for sstate. It
does not take into account the equivalence of the values. In current
code, considering 'bb.utils.contains_any("A", "foo bar", ...)':
A = "foo"
A = "bar"
A = "foo bar"
All those will get different signatures.

Doing so was causing leakage between the execs of the main value and that of
the subshell value, and was causing the cached subshell value to be used for
the overall variable. At the least this could cause execs contamination
between two variables that while differing, run the same subshell. Beyond
that, it's possible we could have been using an incomplete cached value of
a subshell for that of the main value.
Before this, bb_codeparser.dat would change between parses with differing
bbfile parse order. After, it does not change.
The codeparser cache version is bumped, to ensure we don't use potentially
incorrect cached values from previous runs.
This should hopefully resolve the difficult-to-reproduce issues we've seen at
Mentor Graphics where bitbake emits a script to run a task and misses
dependent functions, resulting in 'command not found' failures. This issue has
also been mentioned on the oe devel list, where someone hit a case where
oe_runmake was missing from a do_install task (IIRC). Adding debug information
showed that bitbake's information about the variable dependencies for this
task is inaccurate in the failure cases.

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.

The bb.utils.contains function usage is getting increasingly used in the metadata
but isn't handled automatically by the python dependency tracking code. This patch
changes that and also adds the "OE" names for the functions.
Whilst there are reasons this is a bad idea, its likely outweighed by the
shear number of these references and the current holes in dependency information
which we're now relying heavily upon.

In the initial implementation there was a relcutance on my part to
generate incremental cache components on the fly since it would lead
to some duplicate code.
We are now seeing problems where each thread reading in the saved cache
file causes significant overhead and can make the process appear to hang
on a many core build, particularly when the cache file is large.
This patch changes the code to maintain the delta in a separate dict
right from the start. The code duplication isn't too bad and could be
mitigated in other ways if it becomes an issue.

There are two usual cases involving bb.data.expand:
- Calling it with a string literal -- "bb.data.expand('${FOO}/${BAZ}/bleh', d)".
- Calling it on getVar results (legacy) -- "bb.data.expand(bb.data.getVar('FOO', d), d)"
Nothing in any of the usual layers uses it in any other way, and I'm
having trouble coming up with any real use cases beyond this. The first
of the above cases is already tracked, via the expandWithRefs called
on the python code string. The second didn't emit a warning anyway,
since the getVar was already handled.
Given this, I see no reason for us to maintain explicit expansion
tracking. Further, we weren't using its results anyway (the var_expands
member).

With the previous method, using the compare_name methods, we split the
requested match name by '.', reversed it, then compared them piecemeal
during the node traversal. The new method walks the nodes and hands back
the name of what's being called, and then we check that. This also
consolidates the two different implementations of traversal of the
attribute/name nodes (one in compare_name, one for the execs).

The current codeparser cache handling hurts performance badly even
over a couple of cores and certainly on many core systems, it can
spent huge amounts of time in the codeparser cache save functions.
This patch reworks the cache handling so that each parsing thread
saves out its own "differences" file compared to any existing core
cache and then the main bitbake thread picks these up and merges
things back together.
This was tested on systems with small and large numbers of cores
and was found to perform orders of magnitude better in all cases
despite the more complex code.

parsing process
Before this change, the codeparser cache was only being saved for the main
server process. This is suboptimal as it leaves code being re-evaluated at
task execution time and increases parse time.
We use the multiprocess Finalize() functionality to ensure each process
saves out its cache. We need to update the cache save function to be multiprocess
friendly with locking.
