* We can ignore Z_BUF_ERROR in flush_libz_buffer because:
When we call libz_func we can assume that - avail_in is zero (due to the surrounding code that calls flush_libz_buffer) - avail_out is non zero due to the fact that we just emptied the output buffer and stored it into a brigade So the only reason for Z_BUF_ERROR is that the internal libz buffers are now empty and thus we called libz_func one time too often. This does not hurt. It simply says that we are done. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@426793 13f79535-47bb-0310-9956-ffa450edef68
