In wxSOCKET_NOWAIT mode wxSOCKET_WOULDBLOCK is not a real error as it's expected and should be just discarded. Failing to do this could result in the following scenario: 1. Try to read a big buffer with wxSOCKET_NOWAIT (setting wxSocket error to wxSOCKET_WOULDBLOCK). 2. Process small part of it. 3. Read more data from wxSocket -- which now goes to the data containing already cached data without going to the socket itself and this without resetting the error. 4. Check wxSocket::Error() which turns out to be (still) true. And this was exactly what happened in mysteriously failing unit test case reading wxImage contents from a socket: the failure was difficult to reproduce because it depended on how much data exactly did we read from the socket in one go. Fix this by resetting the error properly and reenable the unit test which was previously disabled for the build bot, it should pass now. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@65378 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
