Now that it's far enough along to be interesting I'd like to announce more
widely a project I've been working on for the past few months (with support
from ORNL).
The PVXS library is another PVAccess protocol server and client.
This will be a reimplementation of the pvDataCPP and pvAccessCPP modules.
I'm making this announcement now in the hope of soliciting feedback. I am interested
in hearing impressions from those who have used pvDataCPP and pvAccessCPP in anger.
One of my motivations is to create an API which is easier to understand,
and less error prone.
At present, the server component is working, and I think near being feature complete.
It's tested against clients using the pvAccessCPP module (eg. pvget and friends),
and both of the Java implementations. Of course at this stage bugs should be expected.
I haven't started on the client component yet.
The code can be found at https://github.com/mdavidsaver/pvxs
Such documentation as I've written can be found here
https://mdavidsaver.github.io/pvxs/
Note that this code requires a toolchain supporting c++11 or later.
This is gcc >=4.9. It also depends on the libevent library >=2.0 .
While I think the basic form of the server side API is settling down,
it is not finalized and will change to some degree prior to an initial release.
I think a reasonable entry point investigation is the mailbox server demo.
https://github.com/mdavidsaver/pvxs/blob/master/test/mailbox.cpp
I don't have any concise demos of data handling (Value container class).
The code behind the mailbox Put handling is one simple case.
Beyond this, please ask questions.
