In network-2.6 the @Network.URI@ module was split off into its own package, network-uri-2.6. If you're using the @Network.URI@ module you can automatically get it from the right package by adding this to your .cabal file: . > flag network-uri > description: Get Network.URI from the network-uri package > default: True > > library > -- ... > if flag(network-uri) > build-depends: network-uri >= 2.6, network >= 2.6 > else > build-depends: network-uri < 2.6, network < 2.6 . That is, get the module from either network < 2.6 or from network-uri >= 2.6. category: Network build-type: Configure cabal-version: >=1.8 extra-tmp-files: config.log config.status autom4te.cache network.buildinfo include/HsNetworkConfig.h extra-source-files: README.md CHANGELOG.md examples/*.hs tests/*.hs config.guess config.sub install-sh configure.ac configure network.buildinfo.in include/HsNetworkConfig.h.in include/HsNet.h -- C sources only used on some systems cbits/ancilData.c cbits/asyncAccept.c cbits/initWinSock.c cbits/winSockErr.c homepage: https://github.com/haskell/network bug-reports: https://github.com/haskell/network/issues tested-with: GHC == 7.0.4, GHC == 7.4.2, GHC == 7.6.3, GHC == 7.8.4, GHC == 7.10.1, GHC == 7.10.2, GHC == 8.0.1 library exposed-modules: Network Network.BSD Network.Socket Network.Socket.ByteString Network.Socket.ByteString.Lazy Network.Socket.Internal other-modules: Network.Socket.ByteString.Internal Network.Socket.Types if !os(windows) other-modules: Network.Socket.ByteString.IOVec Network.Socket.ByteString.Lazy.Posix Network.Socket.ByteString.MsgHdr if os(windows) other-modules: Network.Socket.ByteString.Lazy.Windows build-depends: base >= 3 && < 5, bytestring < 0.11 if !os(windows) build-depends: unix >= 2 extensions: CPP, DeriveDataTypeable, ForeignFunctionInterface, TypeSynonymInstances include-dirs: include includes: HsNet.h install-includes: HsNet.h HsNetworkConfig.h c-sources: cbits/HsNet.c ghc-options: -Wall -fwarn-tabs test-suite simple hs-source-dirs: tests main-is: Simple.hs type: exitcode-stdio-1.0 build-depends: base < 5, bytestring, HUnit, network, test-framework, test-framework-hunit test-suite regression hs-source-dirs: tests main-is: Regression.hs type: exitcode-stdio-1.0 build-depends: base < 5, bytestring, HUnit, network, test-framework, test-framework-hunit -- Some of the bugs only occur in the threaded RTS ghc-options: -Wall -threaded test-suite doctest hs-source-dirs: tests main-is: doctests.hs type: exitcode-stdio-1.0 build-depends: base < 5, doctest >= 0.10.1 ghc-options: -Wall source-repository head type: git location: git://github.com/haskell/network.git network-2.6.3.1/configure.ac0000644000000000000000000001504512747272314014044 0ustar0000000000000000AC_INIT([Haskell network package], [2.3.0.14], [libraries@haskell.org], [network]) ac_includes_default="$ac_includes_default #ifdef HAVE_SYS_SOCKET_H # include #endif #ifdef HAVE_NETINET_IN_H # include #endif #ifdef HAVE_NETDB_H # include #endif #ifdef HAVE_WINSOCK2_H # include #endif #ifdef HAVE_WS2TCPIP_H # include // fix for MingW not defining IPV6_V6ONLY # define IPV6_V6ONLY 27 #endif" # Safety check: Ensure that we are in the correct source directory.

The maintainer for a long period, Johan Tibell (@tibbe) stepped down. Thank you, Johan, for your hard work for a long time. * New APIs: ntohl, htonl,hostAddressToTuple{,6} and tupleToHostAddress{,6}. [#210](https://github.com/haskell/network/pull/210) * Added a Read instance for PortNumber. [#145](https://github.com/haskell/network/pull/145) * We only set the IPV6_V6ONLY flag to 0 for stream and datagram socket types, as opposed to all of them. This makes it possible to use ICMPv6. [#180](https://github.com/haskell/network/pull/180) [#181](https://github.com/haskell/network/pull/181) * Work around GHC bug #12020. Socket errors no longer cause segfaults or hangs on Windows.

The second method is used -- here since a lot of the C structures are not required to be -- manipulated. -- Originally the status was non-mutable so we had to return a new -- socket each time we changed the status. This version now uses -- mutable variables to avoid the need to do this. The result is a -- cleaner interface and better security since the application -- programmer now can't circumvent the status information to perform -- invalid operations on sockets. -- | Socket Types. -- -- The existence of a constructor does not necessarily imply that that -- socket type is supported on your system: see 'isSupportedSocketType'. data SocketType = NoSocketType -- ^ 0, used in getAddrInfo hints, for example | Stream -- ^ SOCK_STREAM | Datagram -- ^ SOCK_DGRAM | Raw -- ^ SOCK_RAW | RDM -- ^ SOCK_RDM | SeqPacket -- ^ SOCK_SEQPACKET deriving (Eq, Ord, Read, Show, Typeable) -- | Does the SOCK_ constant corresponding to the given SocketType exist on -- this system? isSupportedSocketType :: SocketType -> Bool isSupportedSocketType = isJust . packSocketType' -- | Find the SOCK_ constant corresponding to the SocketType value. packSocketType' :: SocketType -> Maybe CInt packSocketType' stype = case Just stype of -- the Just above is to disable GHC's overlapping pattern -- detection: see comments for packSocketOption Just NoSocketType -> Just 0 #ifdef SOCK_STREAM Just Stream -> Just #const SOCK_STREAM #endif #ifdef SOCK_DGRAM Just Datagram -> Just #const SOCK_DGRAM #endif #ifdef SOCK_RAW Just Raw -> Just #const SOCK_RAW #endif #ifdef SOCK_RDM Just RDM -> Just #const SOCK_RDM #endif #ifdef SOCK_SEQPACKET Just SeqPacket -> Just #const SOCK_SEQPACKET #endif _ -> Nothing packSocketType :: SocketType -> CInt packSocketType stype = fromMaybe (error errMsg) (packSocketType' stype) where errMsg = concat ["Network.Socket.packSocketType: ", "socket type ", show stype, " unsupported on this system"] -- | Try packSocketType' on the SocketType, if it fails throw an error with -- message starting "Network.Socket." ++ the String parameter packSocketTypeOrThrow :: String -> SocketType -> IO CInt packSocketTypeOrThrow caller stype = maybe err return (packSocketType' stype) where err = ioError . userError . concat $ ["Network.Socket.", caller, ": ", "socket type ", show stype, " unsupported on this system"] unpackSocketType:: CInt -> Maybe SocketType unpackSocketType t = case t of 0 -> Just NoSocketType #ifdef SOCK_STREAM (#const SOCK_STREAM) -> Just Stream #endif #ifdef SOCK_DGRAM (#const SOCK_DGRAM) -> Just Datagram #endif #ifdef SOCK_RAW (#const SOCK_RAW) -> Just Raw #endif #ifdef SOCK_RDM (#const SOCK_RDM) -> Just RDM #endif #ifdef SOCK_SEQPACKET (#const SOCK_SEQPACKET) -> Just SeqPacket #endif _ -> Nothing -- | Try unpackSocketType on the CInt, if it fails throw an error with -- message starting "Network.Socket." ++ the String parameter unpackSocketType' :: String -> CInt -> IO SocketType unpackSocketType' caller ty = maybe err return (unpackSocketType ty) where err = ioError . userError . concat $ ["Network.Socket.", caller, ": ", "socket type ", show ty, " unsupported on this system"] ------------------------------------------------------------------------ -- Protocol Families. -- | Address families. -- -- A constructor being present here does not mean it is supported by the -- operating system: see 'isSupportedFamily'. data Family = AF_UNSPEC -- unspecified | AF_UNIX -- local to host (pipes, portals | AF_INET -- internetwork: UDP, TCP, etc | AF_INET6 -- Internet Protocol version 6 | AF_IMPLINK -- arpanet imp addresses | AF_PUP -- pup protocols: e.g. BSP | AF_CHAOS -- mit CHAOS protocols | AF_NS -- XEROX NS protocols | AF_NBS -- nbs protocols | AF_ECMA -- european computer manufacturers | AF_DATAKIT -- datakit protocols | AF_CCITT -- CCITT protocols, X.25 etc | AF_SNA -- IBM SNA | AF_DECnet -- DECnet | AF_DLI -- Direct data link interface | AF_LAT -- LAT | AF_HYLINK -- NSC Hyperchannel | AF_APPLETALK -- Apple Talk | AF_ROUTE -- Internal Routing Protocol | AF_NETBIOS -- NetBios-style addresses | AF_NIT -- Network Interface Tap | AF_802 -- IEEE 802.2, also ISO 8802 | AF_ISO -- ISO protocols | AF_OSI -- umbrella of all families used by OSI | AF_NETMAN -- DNA Network Management | AF_X25 -- CCITT X.25 | AF_AX25 | AF_OSINET -- AFI | AF_GOSSIP -- US Government OSI | AF_IPX -- Novell Internet Protocol | Pseudo_AF_XTP -- eXpress Transfer Protocol (no AF) | AF_CTF -- Common Trace Facility | AF_WAN -- Wide Area Network protocols | AF_SDL -- SGI Data Link for DLPI | AF_NETWARE | AF_NDD | AF_INTF -- Debugging use only | AF_COIP -- connection-oriented IP, aka ST II | AF_CNT -- Computer Network Technology | Pseudo_AF_RTIP -- Help Identify RTIP packets | Pseudo_AF_PIP -- Help Identify PIP packets | AF_SIP -- Simple Internet Protocol | AF_ISDN -- Integrated Services Digital Network | Pseudo_AF_KEY -- Internal key-management function | AF_NATM -- native ATM access | AF_ARP -- (rev.) addr. res. prot.
