[bitbake-devel] [PATCH] bitbake: fetch2/svn: Add tarsnapshots parameter

[Niko Mauno]

By adding 'tarsnapshots=currentonly' option to svn-specific component in
SRC_URI, associated subversion repository module's existing tarball
snapshots are removed from DL_DIR, before creating a new one.

This provides a means to avoid downloads directory becoming congested
with a subversion repository module's tarball snapshots, which may occur
for example during circumstances where source code residing in a
subversion repository is subject to long-term development work, and
recipe used in continuous integration builds has SRCREV set to AUTOREV.
