From 9461854a3cf64a1d8fbf0248140d91bbd0a8e054 Mon Sep 17 00:00:00 2001 From: Robert Yang Date: Wed, 1 Aug 2012 15:18:18 +0800 Subject: bitbake: contrib/dump_cache.py: dump recipe -> packages mapping from bb_cache.dat Add the dump_cache.py to dump the "recipe -> packages" mapping for target recipes form bb_cache.dat: * Usage: dump_cache.py bb_cache.dat * The format is: recipe_path pn pv packages For example: /path/to/gzip_1.5.bb gzip 1.5 gzip-dbg gzip-staticdev gzip-dev gzip-doc gzip-locale gzip * Only save the mapping for the target recipe * We can extend this to dump other informations when needed. * Put this script to bitbake/contrib/ (not to oe-core) is because it needs the bb.cache.
