Richard Purdie 400f53003e bitbake: build: Improve python execution tracebacks
If something fails in a exec_func_python() the current stack trace shows
incorrect filenames and linenumbers. For example:

The stack trace of python calls that resulted in this exception/failure was:
File: '/media/build1/poky/meta/recipes-sato/images/core-image-sato.bb', lineno: 200, function: <module>
     0196:                chksum = bb.utils.sha256_file(fn)
     0197:                f.write('%s\t%s\n' % (chksum, os.path.relpath(fn, baseoutpath)))
     0198:
     0199:
 *** 0200:copy_buildsystem(d)
     0201:
File: '/media/build1/poky/meta/recipes-sato/images/core-image-sato.bb', lineno: 9, function: copy_buildsystem
     0005:IMAGE_FEATURES += "splash package-management x11-base x11-sato ssh-server-dropbear hwcodecs"
     0006:
     0007:LICENSE = "MIT"
     0008:
 *** 0009:inherit core-image
     0010:
     0011:IMAGE_INSTALL += "packagegroup-core-x11-sato-games"
File: '/usr/lib/python2.7/subprocess.py', lineno: 535, function: check_call
     0531:    The arguments are the same as for the Popen constructor.  Example:
     0532:
     0533:    check_call(["ls", "-l"])
     0534:    """
 *** 0535:    retcode = call(*popenargs, **kwargs)
     0536:    if retcode:
     0537:        cmd = kwargs.get("args")
     0538:        if cmd is None:
     0539:            cmd = popenargs[0]

The problem is the use of "FILE" to obtain the current filename. Instead,
we therefore inject the function being executed into the methodpool which
allows us to correct its linenumber and filename information. We can then
clearly mark the initial piece as autogenerated and the rest of the linenumber
and filename information should be correct. Afterwards the trace starts:

The stack trace of python calls that resulted in this exception/failure was:
File: 'exec_python_func() autogenerated', lineno: 2, function: <module>
     0001:
 *** 0002:copy_buildsystem(d)
     0003:
File: '/media/build1/poky/meta/classes/populate_sdk_ext.bbclass', lineno: 66, function: copy_buildsystem
     0062:    import glob
     0063:    import oe.copy_buildsystem
     0064:    import subprocess
     0065:
 *** 0066:    subprocess.check_call("foo")
     0067:
     0068:    oe_init_env_script = d.getVar('OE_INIT_ENV_SCRIPT', True)
     0069:
     0070:    conf_bbpath = ''
File: '/usr/lib/python2.7/subprocess.py', lineno: 535, function: check_call
     0531:    The arguments are the same as for the Popen constructor.  Example:
     0532:
     0533:    check_call(["ls", "-l"])
     0534:    """
 *** 0535:    retcode = call(*popenargs, **kwargs)
     0536:    if retcode:
     0537:        cmd = kwargs.get("args")
     0538:        if cmd is None:
     0539:            cmd = popenargs[0]

We can't inject into methodpool at parsing time, since there may be
_append or other override operations against the function before its
execution.
