This release is essentially a recompilation of the Pup and Ftp packages using Mesa 6.0. As usual, a number of bugs have also been fixed, and minor changes have been made to the interfaces. More complete information is available in the functional specifications stored on Doc> as PupPackage.press and FtpPackage.press.x2e12jk40\390f8 10f0 4f8 16f0 5f8 16f0 Pup Summaryx2e18jk60\b11B Changesx2e12jk60\i7I The following changes were made to Stream. The procedure types GetProcedure, PutProcedure, SetSSTProcedure, SendAttentionProcedure, and WaitAttention-Procedure now take a new initial argument sh: Handle. In addition, SendAttention-Procedure now takes a second argument byte: Byte (which is ignored), and WaitAttentionProcedure now returns a Byte (which should be ignored). As a result of these type redefinitions, the inline procedures SendAttention and WaitAttention have different calling sequences, and a new return value has been added to WaitAttention.x2e12jk40\35f6b6f0B23f6b12f0B2f6b12f0B2f6b15f0B2f6b22f0B6f6b23f0B33f6b10f0B16f6b23f0B29f6b10f0B25f6b22f0B15f6b4f0B92f6b13f0B5f6b13f0B76f6b13f0B The following changes were made to PupDefs. PupRouterSendThis no longer returns a SendReturnCode. SendReturnCode (a TYPE) has been deleted. If the buffer could not be sent, it is discarded.x2e12jk40\35f6b7f0B3f6b17f0B21f6b14f0B3f6b14f0B4f7 4f0 The arguments to EnumeratePupAddresses are now named. The order of the two arguments to PupAddressLookup has been reversed. The second argument to AppendPupAddress is now a PupAddress, instead of a POINTER TO PupAddress. Similarly, the argument to Print-PupAddress is now a PupAddress, instead of a POINTER TO PupAddress. The local: PupSocketID argument to PupPktStreamCreate and PupByteStreamCreate has been removed.x2e12jk40\17f6b21f0B51f6b16f0B44f6b16f0B10f6b10f0B15f7 10f0 1f6b10f0B30f6b16f0B10f6b10f0B15f7 10f0 1f6b10f0B7f6b18f0B13f6b18f0B5f6b19f0B Additionsx2e12jk60\i9I The procedures AppendHostName and AppendMyName have been added to PupDefs.x2e12jk60\15f6b14f0B5f6b12f0B20f6b7f0B UseAltoChecksumMicrocode has been added to speed up processing if you are running on an Alto with XMesa in the ROM or an Alto with a 3K RAM. The overflow microcode loaded into the RAM by RunMesa.run includes the necessary additions. (Beware if you load your own microcode.)x2e12jk60\f6b24f0B87f1 3f0 22f1 3f0 42f1 3f0 4f8 11f0 Subtle Implementation Changesx2e12jk60\i29I GetPupAddress will no longer return an address for a dying net. EnumeratePupAddresses will now pass the client supplied procedure addresses on dead or dying nets, but only after processing all the addresses on nets that are reachable. (It used to skip addresses on unreachable nets.)x2e12jk60\f6b13f0B52f6b21f0B The byte stream internals have been reworked to eliminate several unpleasant delays while opening and closing connections. It is now possible to open a connection, send a thousand words, and close the connection in less than a second. (Since closing deletes three module instances, it will take longer if there are many active global frames.) A byproduct of this cleanup is that SendNow will send an empty aData packet to request an acknowledgment even if the previous SendBlock happened to end on a convenient packet boundary.x2e12jk60\382f6b7f0B20f6b5f0B58f6b9f0B When sending a packet whose destination is the local machine, the Ethernet driver puts a copy on the input queue and acts as though it had sent the packet. It now also copies broadcast packets to the input queue, so clients should check to be sure that their programs will not take undesired actions if they hear their own broadcasts. Packets that are sent to the local machine are now also sent out over the wire; this allows PeekPup.run to be used when analyzing timing problems.x2e12jk60\429f6 11f0 Bug Fixesx2e12jk60\i9I The following change requests are closed by this release:x2e12jk40 2848 GetMyName (actually net address) procedure 2906 Slow on Dorado 2998 Error strings in NameConversion 3311 Pup ByteStream close 3341 Trivial bug in PupTypes 3708 PupNameLookup+PupAddressLookup PupGlitch 4456 Recompile packages to fix long return record bug 4552 ByteStream timeout 5005 Delays when creating byte stream 5093 NameLookup vs dying nets 5098 Change priority of interrupt routine in EthernetDriver(s)l4269x2e6jk60\5f6b9f0B76f6b14f0B47f6b8f0B6f6b13f0B1f6b16f0B1f6b9f0B Ftp Summaryx2e18jk60\b11B The arguments to the (client supplied) procedure passed to FTPInventoryDumpFile have been extended to allow proper processing of create dates.
