bitbake: bitbake: data_smart.py and friends: Track file inclusions for bitbake -e
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. RP Modifications: a) Split Include and Variable tracking b) Replace deepcopy usage with dedicated copy function c) Simplify some variable and usage (Bitbake rev: b2dda721262da8abb7dc32d019e18fbc32ed8860) Signed-off-by: Peter Seebach <peter.seebach@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
