a0a9ee4553 ca: Avoid possible race condition during cac shutdown. 
While the cac dtor runs and waits for TCP circuit threads to exit,
new circuits could be opened by name resolution replies on existing
(still active) circuits.
Avoid this by setting a flag (lock being held) in the dtor, and
checking it in cac::transferChanToVirtCircuit.

7af0397d58 Examining the previous change I see that it will introduce a race condition when circuits are being created and destroyed at close to the same instant in time. See revision 11786 of cac.cpp which fixes mantis 334 if you are interested in what this code does. After running the regression tests, I pushed in a fix (which is removing above mentioned change and restoring the increment of iiuExistenceCount in cac::findOrCreateVirtCircuit. 2010-08-16 17:45:06 -06:00

be978d6499 Fixed issue "TCP Nameserver Connection Down Blocks All Callbacks" and cleaned up the SearchDest list / TCP circuit relation 
* Pulled out tcpiiu::SearchDestTCP to have cac create the SearchDest independent from the TCP circuit
* Reorganized the relation between the SearchDestTCP and the TCP circuit:
  - SearchDest stays always on the cac list
  - TCP connection going down sets SearchDest inactive and SearchDestTCP's circuit member to NULL
  - Next seach request creates the new TCP circuit and sets SearchDestTCP's member, but leaves SearchDest inactive
  - Successful connect sets SearchDest active
* ReceiveThread releases the cac mutex before going to sleep in connect loop

b344841365 fixed the following issues with detection of flow control mode 
o the flow control contig frame thresh should be based on max array size
o it appears that the wakeup mechanism for the send thread, who sends
the flow control on/off messages was broken
o looking at full buffers isnt a perfect detection scheme compared to
the simpler approach of just checking to see if bytes are pending in
the socket before calling recv
