If you have an existing working copy that was checked out using
http://subversion.assembla.com/svn/chdk/... rather than https:... you may get an error like
svn: E170011: Repository moved temporarily to 'https://subversion.assembla.com/svn/chdk/trunk'
You can fix it using the "svn relocate" command like
svn relocate http: https: /path/to/wc
or the relocate option in Tortoise to fix it.
The
https://mighty-hoernsche.de/ autobuild scripts may be affected by this (the last copy I have appears to use tools.assembla.com which doesn't currently seem to redirect). I've dropped hacki a note, but it may fall behind the current rev or break in the meantime. The build.chdk.photos autobuild was already using https, so should be unaffected.
