The flow is largely unsynchronized, but our function may have to respond to things like authorization requests. Perhaps we do a recvContents and then mapM_ over that ? Not all incoming messages require a response. We probably also need to track state, for example, if we are pipelining multiple downloads and want to show seperate progress bars for each download. If someone wants to use fetch, they will need to provide methods to: 1. prompt for and provide authentication 2. show progress 3. show media change dialog 4. Show log messages 5. Show failures 6. Send Configuration pipeline vs non-pipeline mode. what if different methods are being used ? when pipelining, we probably don't want to have too many pipelines to the same server. Perhaps there can be a limit, and for non-pipelinable methods, we set the limit to 1. Each method can run in a seperate thread, since methods do not interact with each other. In fact, each unique method+uri can be a seperate thread. We can use a MVar to track the global max download count. Perhaps we also want a per host throttle, since it is the host connect that is likely to max out, not the access method. Plan: partition fetches by (host,method). fork off threads for each (host, method). Use MVar to throttle per host, and total connections We don't know if a method supports pipelining until we connect atleast once. So if we have a non-pipelined method, we might want to start multiple streams. On the other hand, for something like a CDROM, that will just cause the system to thrash. cdrom, file, etc, don't have a host, so that is not a unique key then. Pipelining on local methods is tricky, because it is hard to tell if the local methods point to the same device or not. Even though we have multiple threads, the interactor can view the incoming Stream as a single Stream because all the events are tagged with the URI (i think). But, sending commands involves a fancy router. We could include a reference to corresponding command for each stream. For now, let's serialize the transfers, but allow pipeling for methods that really allow pipelining. -} data FetchCallbacks = FetchCallbacks { logCB :: Message -> IO () , statusCB :: URI -> Message -> IO () , uriStartCB :: URI -> Maybe Integer -> Maybe UTCTime -> Maybe Integer -> IO () , uriDoneCB :: URI -> Maybe Integer -> Maybe UTCTime -> Maybe Integer -> Maybe FilePath -> Hashes -> Bool -> IO () , uriFailureCB :: URI -> Message -> IO () , generalFailureCB :: Message -> IO () , authorizationRequiredCB :: Site -> IO (Maybe (User, Password)) , mediaFailureCB :: Media -> Drive -> IO () , debugCB :: String -> IO () } simpleFetch :: [ConfigItem] -> URI -> FilePath -> Maybe UTCTime -> IO Bool simpleFetch = fetch cliFetchCallbacks -- |fetch a single item, show console output -- see also: getLastModified fetch :: FetchCallbacks -> [ConfigItem] -> URI -> FilePath -> Maybe UTCTime -> IO Bool fetch cb configItems uri fp lastModified = do withMethodURI uri $ \mh -> do s <- recvStatus mh debugCB cb ("<- " ++ show s) sendCommand' mh (URIAcquire uri fp lastModified) loop mh where sendCommand' mh c = do mapM_ (debugCB cb .

The maintainer name and email address used in the changelog should be the details of the person uploading this version. They are not necessarily those of the usual package maintainer. The information here will be copied to the Changed-By field in the .changes file (see Changed-By, Section 5.6.4), and then later used to send an acknowledgement when the upload has been installed. The date must be in RFC822 format[17]; it must include the time zone specified numerically, with the time zone name or abbreviation optionally present as a comment in parentheses. The first "title" line with the package name must start at the left hand margin. The "trailer" line with the maintainer and date details must be preceded by exactly one space. The maintainer details and the date must be separated by exactly two spaces.
