With the addition of function line number handling, the overhead of
the compile functions is no longer negligible. We tend to compile
the same pieces of code over and over again so wrapping a cache around
this is beneficial and removes the overhead of line numbered functions.
Life cycle of a cache using a global like this is in theory problematic
although in reality unlikely to be an issue. It can be dealt with
if/as/when we deal with the other global caches.

correctly
Currently bitbake tracebacks can have places where the line numbers are
inaccurate and filenames may be missing. These changes start to try and
correct this.
The only way I could find to correct line numbers was to compile as a
python ast, tweak the line numbers then compile to bytecode. I'm open
to better ways of doing this if anyone knows of any.
This does mean passing a few more parameters into functions, and putting
more data into the data store about functions (i.e. their filenames
and line numbers) but the improvement in debugging is more than worthwhile).

Having a global method scope confuses users and with the introduction
of parallel parsing, its not even possible to correctly detect conflicting
functions. Rather than try and fix that, its simpler to retire the global
method scope and restrict functions to those locations they're defined
within. This is more what users actually expect too.
If we remove the global function scope, the need for methodpool is reduced
to the point we may as well retire it. There is some small loss of caching
of parsed functions but timing measurements so the impact to be neglibile
in the overall parsing time.

When this error occurs, the build should stop, not continue uninterrupted.

This removes some dubious functions and replaces them with a simpler, cleaner
API which better describes what the code is doing. Unused code/variables are
removed and comments tweaked.

The current error message is confusing, this improves it to explain the problem
and the possible ways to resolve it.

The methodpool, ${@} expansions, anonymous python functions, event handlers
now all run with the same global context, ensuring a consistent environment
for them. Added a bb.utils.better_eval function which does an eval() with the
same globals as better_exec.

BitBake trunk is now GPLv2 only, no mix of
MIT,FreeBSD License is left.
Update GPL headers to point to the correct
address of the FSF
Update the list of authors. Uli Luckas,
Seb Frankengul and Tim Amsell contributed to
the sourcecode as well

This reduces the time of the new parser from 2:42 to
1:6. The old one takes 1:42 on this macbook here

-Extract the names from the just compiled code
-Iterate over each key (leaving out Keys and None)
-And see if we have seen the name already.
-If we have seen it, raise an error...
|
|
-Document the usage of the three variables
|
|
-Revert the last change. We have no method names available
which makes tracking of replacing not possible...
|
|
-Add sanity check to the methodpool. If the same method
is registered by two differen files then we will throw
an error
|
|
-Fix the method invocation in methodpool
to use the right amount of arguments
-Update data_smart to the new cache layout
of the file functions
|
|
Create a common implementation of the global
method handling. It will be shared by the parsers
and the cache.
This commit breaks the cache again
