Release 7.0.0 (July 2019)
|
||||
=========================
|
||||
|
||||
- Incompatible changes
|
||||
- Peers claiming protocol minor version 0 are ignored. The change from 0 -> 1 included incompatible changes
|
||||
to CMD_BEACON and several others network messages, and inter-operation was never possible.
|
||||
Attempts resulted in printing error messages to console.
|
||||
- The Access Security interface classes in pv/security.h are completely redesigned.
|
||||
The SecurityPlugin interface is replaced with epics::pvAccess::AuthenticationPlugin and epics::pvAccess::AuthorizationRegistry
|
||||
as separate phases to connection setup. Each connection will select one epics::pvAccess::AuthenticationPlugin
|
||||
and zero or more epics::pvAccess::AuthorizationPlugin s. The result of this process is a epics::pvAccess::PeerInfo
|
||||
which may be accessed with with epics::pvAccess::ChannelFindRequester::getPeerInfo()
|
||||
and epics::pvAccess::ChannelRequester::getPeerInfo() .

- Fixes
|
||||
- Implement idle timeout on TCP connections.
|
||||
Introduces minor protocol version 2. Connections between v2 peers send a CMD_ECHO message from client -> server.
|
||||
Either side will close the TCP connection if no message has been received within the past 30 seconds (by default).
|
||||
This can be configured with $EPICS_PVA_CONN_TMO .

========================
|

|
||||
- Changes
|
||||
- When available, use environment variable defaults from Base
|
||||
- Relax state check in epics::pvAccess::MonitorFIFO::post() and tryPost() to allow post() while closed.
|
||||
Allows user code to avoid extra synchronization during shutdown (just call close() ).
|
||||
Synchronization between open() and post() on type change is still required.

to receive notification of initial window size.
|

- Most locking issues in the 'ca' provider should now be resolved.

Release 6.0.0 (Dec 2017)
|
||||
========================
|
||||
|
||||
- Incompatible changes
|
||||
- Requires pvDataCPP >=7.0.0 due to headers moved from pvDataCPP into this module: requester.h, destoryable.h, and monitor.h
|
||||
- Major changes to shared_ptr ownership rules for epics::pvAccess::ChannelProvider and
|
||||
associated classes. See
|
||||
- @ref providers
|
||||
- @ref providers_changes
|
||||
- Add new library pvAccessIOC for use with PVAClientRegister.dbd and PVAServerRegister.dbd.
|
||||
Necessary to avoid having pvAccess library depend on all IOC core libraries.
|
||||
- Added new library pvAccessCA with "ca" provider. Main pvAccess library no longer depends on libca.
|
||||
Applications needing the "ca" provider must link against pvAccessCA and pvAccess.
|
||||
See examples/Makefile in the source tree.
|
||||
The headers associated with this library are: caChannel.h, caProvider.h, and caStatus.h
|
||||
- A number of headers which were previously installed, but considered "private", are no longer installed.
|
||||
- epics::pvAccess::ChannelProviderRegistry may no longer be sub-classed.
|
||||
- Removed access to singleton registry via getChannelProviderRegistry() and registerChannelProviderFactory()
|
||||
in favor of epics::pvAccess::ChannelProviderRegistry::clients() and epics::pvAccess::ChannelProviderRegistry::servers().
|
||||
The "pva" and "ca" providers are registered with the clients() singleton.
|
||||
epics::pvAccess::ServerContext() looks up names with the servers() singleton.
|
||||
- Removed deprecated epics::pvAccess::Properties
|
||||
- The data members of epics::pvAccess::MonitorElement become const, preventing these pointers from being re-targeted.
|
||||
- Requires pvDataCPP >=7.0.0 due to headers moved from pvDataCPP into this module: requester.h, destoryable.h, and monitor.h

- Removed deprecated epics::pvAccess::Properties
|
||||
- The data members of epics::pvAccess::MonitorElement become const, preventing these pointers from being re-targeted.
|
||||
- Simplifications
|
||||
- use of the epics::pvAccess::ChannelRequester interface is optional
|
||||
and may be omitted when calling createChannel().
|
||||
Channel state change notifications are deliviered
|
||||
to individual operations via epics::pvAccess::ChannelBaseRequester::channelDisconnect()
|
||||
- Default implementions added for the following methods
|
||||
- epics::pvAccess::Lockable::lock() and epics::pvAccess::Lockable::unlock() which do nothing.
|
||||
- epics::pvAccess::Channel::getConnectionState() returns CONNECTED
|
||||
- epics::pvAccess::Channel::isConnected() uses getConnectionState()
|
||||
- epics::pvAccess::Channel::getField() which errors
|
||||
- epics::pvAccess::Channel::getAccessRights() which returns rw
|
||||
- Added epics::pvAccess::SimpleChannelProviderFactory template and
|
||||
epics::pvAccess::ChannelProviderRegistry::add() avoids need for custom
|
||||
factory.
|
||||
- Added epics::pvAccess::MonitorElement::Ref iterator/smart-pointer
|
||||
to ensure proper handling of calls Monitor::poll() and Monitor::release().
|
||||
- epics::pvAccess::PipelineMonitor "internal" is collapsed into epics::pvAccess::Monitor.
|
||||
PipelineMonitor becomes a typedef for Monitor.
|
||||
- epics::pvAccess::RPCService is now a sub-class of epics::pvAccess::RPCServiceAsync
|
||||
- use of the epics::pvAccess::ChannelRequester interface is optional
|
||||
and may be omitted when calling createChannel().

|
||||
- Deliver disconnect notifications to individual Operations (get/put/rpc/monitor/...) via
|
||||
new epics::pvAccess::ChannelBaseRequester::channelDisconnect()
|
||||
- New API for server creation via epics::pvAccess::ServerContext::create() allows direct specification
|
||||
of configuration and ChannelProvider(s).
|
||||
- Add epics::pvAccess::ServerContext::getCurrentConfig() to get actual configuration, eg. for use with a client.
|
||||
- Classes from moved headers requester.h, destoryable.h, and monitor.h added to epics::pvAccess namespace.
|
||||
Typedefs provided in epics::pvData namespace.
