Michael Davidsaver 5c8e5c52ef rsrv: fix recv() error handling on WIN32 
For WIN32 osiSockIoctl_t is unsigned, so

> osiSockIoctl_t nchars = recv(...

is casting signed -> unsigned which treats
errors as success.

Michael Davidsaver 1f8cb740f1 rsrv: drop un-commited VERSION message 
This is a no-op as cas_commit_msg() isn't called.
A VERSION message is already queued during create_tcp_client().

Michael Davidsaver 0fc770166c rsrv: avoid possible overflow in vsend_err() 
Accounting of message size doesn't take into account
space used by header of failed message (16 or 24 bytes).
This would allow a theoretical really long error message
to overflow the send buffer by 16 or 24 bytes.

Andrew Johnson 9c859ffdca Protect casStatsFetch() if called before rsrv_init()

Michael Davidsaver 51dd371784 rsrv: add rsrvCS_shutdown to avoid race in destroyAllChannels() 
A race can occur between rsrv and cac by way of asLib
whereby casAccessRightsCB() is called after
a channel_in_use has been removed from
chanList/chanPendingUpdateARList.
casAccessRightsCB() would then attempt to remove
the node again, causing corruption.

Create a new rsrvCS_shutdown state when the
channel is not in either list.

Andrew Johnson c5ded30684 Extended asTrapWrite to provide put data 
Backwards-compatible enhancement to the asTrapWrite API to provide
listener routines with the data being put by the client.
The asTrapWriteMessage structure is extended with 3 new fields
for data type, element count and a pointer to the source buffer.

Tim Mooney requested this enhancement for his caPutRecorder code,
which doesn't work if the record overwrites the new value within
its process() routine, e.g. when jogging a motor record.

Michael AbbottandAndrew Johnson 9d9ba1a442 Add CA message header size optimisation. 
If a packet is sufficiently small it can be worth the small
optimisation of saving the 8 bytes in a large packet header.

Michael AbbottandAndrew Johnson e87bbef75c Update rsrv to support V4.13 protocol extension. 
The rsrv server is updated in this commit to deliver variable sized
waveforms in response to a zero length request, implementing an
extension to the v4 EPICS protocol tied to minor version 13.

The core of the changes are in read_reply, rsrv/camessage.c, which first
reserves packet space for the largest possible response, but then resizes
the packet according to how much data is actually returned from the
database.

Janet B. Anderson a5ea63f7d8 RCS files now used for all cygwin and mingw builds. 2008-08-27 18:33:59 +00:00
Andrew Johnson c9bc70bd6a Added iocBuild, iocPause and iocRun commands. 
These are mainly for redundant IOCs, but may be useful elsewhere.
iocBuild prepares the IOC and freezes it just before it goes live.
A subsequent iocRun kicks it into life, or restarts it when paused.
iocPause freezes all scan tasks and disconnects the server.
