Changes in Dad 1.35 since 1.30

• Dad can now write evcat format on dad files. The flag CAC_CHECKSUM does enable this format which packs records into a frame of |framelength|buffer|checksum|.
• Update Access to a server without a keytable/file in the server connected to this dataflow is now possible.
• Metatable comparison did not check dimension for projector generation.
• Make fasthac again Adamo compatible... Needs Adamo 3.3 July95 or later. This means that dad now compiles with either the hermes ADAMO library or any ADAMO library which was released after July 95.
• Alphas need alignment of 8bytes. Bug in parser got fixed.
• SunOsRef - the funny reference system for a generic SUN at Cern needs a special configuration entry and got it.
• Fixed dadAcceptSelect binding for ultrix (strip off last char).
• Open listener after reading in possible log files in the server. This avoids timeouts for connected clients when reading in the journal files.
• Changed dadMulMsg call so that tabid and rowid become vectors for each socket. This is needed as so_act will act on all sockets which have complete blocks at a given time.
• A new call dadReleaseFile allows the server to release the database file.
• Messages could be lost if booking clients were not in the message loop and send commands to the message socket.
• dadHost does now also regard "" strings as default - so f77 can use the defaults, too.
• Added a new option '-x' at startup to force a startup even if a previous startup has failed / was aborted. The Information Dataflow was extended by DadUser to give connection information.
• Journal files did not contain time corrections for the original sender machines.
• Included integer arithmetics into the parser.
• Initialize an uninitialized string passed to ASKACC.
• Fix some of the newly introduced integer functions of the parser.
• Fix bug in updating mechanism.
• Fix for the faulty SGI daylight saving time handling. You will need an additional dadzone.inf file in either $DAD_LIB or $HERMES_ROOT/lib on SGIs.
• dadDoConnect (and all Open Routines) did not return an error if the max number of files was open, and in addition dadClose routines did not close properly so that a file table overflow was always happening with many close open actions.
• dadRewind can now also act on read-only Dad Files.
• dadOpenDB, dadHost and dadDoConnect can use a new Open mode to connect to a server. With CAC_NOSYNC no time synchronization is tried - even if the server and client system times differ.
• A new connection type "WMEM" and "RMEM" is introduced for (on SGIs) fast information exchange as the pipes are handles there VERY inefficient.
• dadOpenDB, dadHost and dadDoConnect should be called with an additional flag CAC_KEEPEXEC to keep a file handle for the server connection open in the case of an exec. This is needed as some spawned and dirty processes seem to change the clients file connections to the server and therefore the files are now automaticly close_on_exec per default.

Incompatibilies

• dadMulMsg, see above.
