Subject: [bitbake-devel] bitbake/fetch: If checksums are available,
	check them for any file, local or remote
Date: Sun, 13 May 2012 12:36:40 -0000
From: Richard Purdie <richard.purdie@linuxfoundation.org>
X-Patchwork-Id: 27533
Message-Id: <1336912600.2711.12.camel@ted>
To: bitbake-devel <bitbake-devel@lists.openembedded.org>

Currently, checksums are only checked for remote files. This changes
the check to apply to any file we have checksum data for. A mismatch
against a file is fatal but in the local case, no warnings are shown
about missing checksums.
