	The error is not global since we don't use "from os import *", so it should be os.error. [YOCTO #4489] Signed-off-by: Robert Yang <liezhi.yang@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2013-05-09	clases/lib: Use modern exception syntax	Richard Purdie	1

2013-03-18	package: Add cachedpath optimisation	Richard Purdie	1
	Currently, various standard library operations like os.walk(), os.path.isdir() and os.path.islink() each call stat or lstat which involves a syscall into the kernel. There is no caching since they could conceivably have changed on disk. The result is that for something like the do_package task of the kernel we're spending over two minutes making 868,000 individual stat calls for 23,000 files. This is suboptimal. This patch adds lib/oe/cachedpath.py which are a set of replacement functions for these operations which use cached stat data rather than hitting the kernel each time. It gives a nice performance improvement halving the build time of the kernel do_package. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
