This is probably because the code that downloads that config file uses the cache in fall-back mode, i.e. it always tries to get a fresh version of the file (and update the cache with it) and uses a cached copy only when offline. > 1) Is there a way to avoid download twice? Since the download utility doesn't know about the needs of the code calling it (which is a good thing in terms of orthogonality), the part of the buildout code which recursively evaluates the config files that extend each other would have to be changed to remember which files it already downloaded. It could then either reuse them instead of calling the download utility again, or use the download utility's regular cache mode for any further downloads of the same file. > PS.: If it looks like a bug, I'm volunteer to fix it. If you implement the above (or something better) on a branch, I'd be happy to review it. BTW, this raises the question whether the fall-back mode of the cache should be made selectable with each call to a download utility. Currently, fall-back mode can only be configured when first instantiating a download utility (or by overriding its "fallback" attribute later, which would be ugly as a usage pattern). -- Thomas _______________________________________________ Distutils-SIG maillist - [email protected] http://mail.python.org/mailman/listinfo/distutils-sig
