Hi,
I ran into a bug in the file action of the build controller in the OBS API. Whenever the backend has a file that is exactly of size 8192*n+1 and the last byte is 0x30 = '0' the API cannot deliver the complete file through the path build/:project/:repository/:arch/:package/:filename but delivers only the full 8192 chunks without the final byte. Some debugging demonstrated the the backend itself does still deliver the file correctly but the API does cut off the last byte.
I am not a deep Ruby expert but my interpretation of this behavior is that apparently some part of the code incorrectly interprets a chunk consisting of a single 0x30 = '0' as an empty chunk and thus concludes that the file reading has completed. Especially since it does not seem to happen when the last byte is different from 0x30.
You can reproduce that by just placing a file there of the above style (for instance with "echo -n 0 > foobar.rpm" for the most simple case of n=0) and then try to retrieve it through the API.
