There are two bugs in db_purge zlib support code: 1. Wrong archive streams flushed (copy-paste programming...) 2. `Z_FULL_FLUSH` must not be used as it clears compression dictionary, this ruins compression. Use `Z_SYNC_FLUSH` instead. This fixes BOINC#3145 Signed-off-by: Vitalii Koshura <[email protected]>
