Richard Purdie f966c544aa bitbake: codeparser: Track bb.utils.contains usage
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.

Richard Purdie 7e6f9baae1 bitbake: codeparser: Track appendVar and prependVar calls as we do for getVar
We need to track appendVar and prependVar calls just as we do for getVar in order
to ensure we're not missing variable dependencies.

Richard Purdie 7bf0a790b2 codeparser: Compute extra cache components on the fly rather than later
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.

Christopher Larson 7e436a9845 codeparser: drop expand tracking
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).

Christopher Larson ae96ac1189 codeparser: accept a name for better messages
- If a name is passed to the parser, prepend the messages with "while
  parsing <name>:". This gives a bit more context.
- Tweak the warning messages slightly (they had to be altered anyway to
  inject the variable being parsed).

Before:
  DEBUG: Warning: in call to 'bb.data.getVar': argument ''%s' % var' is \
         not a literal

After:
  DEBUG: while parsing emit_pkgdata, in call of bb.data.getVar, argument \
         ''%s' % var' is not a string literal

Christopher Larson 48d7f5251b codeparser: simplify how we compare the called node names
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).

Christopher Larson 925184a2a7 codeparser: make var_expands actually hold useful information
Previously, it was calling var_expands.update() rather than add(), with
a string argument, resulting in adding each character of that string to
the var_expands set, rather than the string itself.

Richard Purdie fd00566144 bitbake/codeparser: Improve cache handling
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.

Richard Purdie c8928e93dd bitbake/cooker/codeparser: Ensure the code parser cache is saved for each 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.
