contrib/dump_cache.py: make it can dump everything
Have a simple tool to dump bb_cache.dat is useful for investigating and studying bitbake cache. The old contrib/dump_cache.py can dump pn, pv and packages for it, now enhance it dump everything. Here is the usage: $ /path/to/dump_cache.py --help usage: dump_cache.py [-h] [-r RECIPE] [-m MEMBERS] [-s] cachefile bb_cache.dat's dumper positional arguments: cachefile specify bb_cache.dat optional arguments: -h, --help show this help message and exit -r RECIPE, --recipe RECIPE specify the recipe, default: all recipes -m MEMBERS, --members MEMBERS specify the member, use comma as separator for multiple ones, default: all members -s, --skip skip skipped recipes Use dump_cache.py --help to get help Signed-off-by: Robert Yang <liezhi.yang@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
