Ted Ross commented on QPID-1982:
--------------------------------
Another possibility is to use sys/PipeHandle.h which already has a windows
implementation and appears to use "int" as its handle type. Does this make
sense?
> QMF ResilientConnection notifyFd feature portability

> Key: QPID-1982
> URL: https://issues.apache.org/jira/browse/QPID-1982
> Project: Qpid
> Issue Type: Improvement
> Components: Qpid Managment Framework
> Affects Versions: 0.5
> Environment: Windows
> Reporter: Steve Huston
>
> The QMF's C++ qmfcommon ResilientConnection class has a setNotifyFd (int fd)
> method. The docs say this can receive a file descriptor that is written on
> when certain events take place, supposedly so the other end of the channel
> can listen, select, etc. and be notified of some event.
> This construct isn't portable, both because of the datatype of the fd (int is
> not necessarily a legit handle type everywhere) and because the code assumes
> a write() will work. The code can be abstracted out to get rid of the write()
> easily enough, but what is the usage for this facility? There are no calls to
> setNotifyFd() that I can find outside of the library containing the
> implementation. So I can't tell if this is something that can be replaced by
> qpid::sys::PollableCondition or not.
> What is the use case for this, and how can we make this portable? Different
> IPC type? Callback to some private hook?
