There was a bug when converting ascii string format to time stamp. The +bug involved the year 00 appeared in the ascii string +
Channel Access +
The CA comments are from Jeff Hill. +
1) I fixed a severe problem where the CA client did not exit a loop
+sending UDP to a list of addresses if an error condition was returned from
+the system call which sends a UDP frame. This problem was discovered by
+me during heavy load testing, and if
+
it occurs in an operational system it will probably be occurring under
+heavy network loading conditions.
+
2) I fixed a problem where the client library could fail and use a deallocated +data structure if a connection dropped while it was waiting to send a message +to a client. +
3) The CA client now maintains a congestion avoidance threshold on UDP +search transmissions similar to the congestion avoidance algorithm employed +by modern version of TCP. There are also some small changes related to +how the search counters are maintained without allowing them to overflow. +This patch was made in R3.13.1 because I originally identified it as the +fix for (1) above, but it turned out to not be the root cause. +
4) A bug fix was made for Ralph Lange's problem where the CA repeater +was inheriting on HP-UX, and possibly other UNIX systems that are not Solaris, +certain open file descriptors when fork()/exec() are used to start the +CA repeater. +
5) Changes that allow CA to work on Microsoft Visual C++ 6.0 (which +includes a new win sock DLL and some changes in esoteric parts of the socket +API). +
6) always inform client of "no write access" for a SPC_NOMOD +fields. +
7) calls to ca_printf removed from rsrv. +
8) prevent UDP daemon from running damaged messages with TCP protocol +and visa-versa +
9) use ipAddrToA() so that address print out does not come out byte +swapped on the PC +
10) improved debug messages and added diagnostics +
11) dont send an exception to client when bad request received
+over udp.
