Changes in Dad 1.20 since 1.10
- A new function
dadMulMsg which allows to wait for
information on multiple sockets.
- Another new function
dadRepUpdate to overwrite old
information with timestamps in a given period of time.
- Two functions
dadPrevUpdate which return
time information at which the current updated dataflow looses
dadWUpdate is now documented to
set the iTimeEnd flag to
Servers now use
3 files for running. This is the real RZ file,
a backup of the state at server startup and a journal file which
a server can use to recover from backup.
Suppose the RZ file connected
to a served dataflow. This means a server crash does no longer
mean loss of data!
Stale unix sockets are detected at startup and automaticly removed.
- A bugfix in dadInit which could not
read in the k flag for keytable access, introduced in
Version 1.10. Also empty lines are now allowed in dadinit.cnf.
- A bugfix in dadAcceptSelect
which crashed the server.
- Removed asserts from the server code to let a server stay alive
even if the client sends garbage.
- CAC_GENTABLES can now be used even
if the table exists already. A projection is generated if needed.
- Various checks on the servers ddl are performed at startup
time to prevent at least some of the possible user errors.
- Fixed a severe bug that crashed the client if
CAC_KEYTABLE was used. Thanx to
Clients from 1.20 can no longer communicate to servers before
1.20. The server will complain about an unknown function if
the updating mechanism is used.
