Removed complete support for emulated C++ exceptions +. The ACE::handle_ready() family of methods was changed to prefer using + poll() over select() on platforms where poll() is available. This preference + was previously only used if ACE_HAS_LIMITED_SELECT was set. The + ACE_HAS_LIMITED_SELECT choice is removed, making ACE_HAS_POLL the + setting that switches this preference. The driving reason for this + is that if select() is called to detect changes on a handle whose + values falls outside that which can safely be stored in an fdset, + the handle-setting macros/functions will set/clear bits outside + of the fdset. This results in very weird memory changes, often in + the stack, which are very hard to diagnose. poll()'s operation + does not suffer from this affect. With the growing use of large + numbers of handles and use of ACE_Dev_Poll_Reactor on Linux, + the rate at which this problem was cropping up was increasing. + USER VISIBLE CHANGES BETWEEN ACE-5.8.0 and ACE-5.8.1 ==================================================== diff --git a/ACE/ace/README b/ACE/ace/README index da3f1f1688c..0edbc40170c 100644 --- a/ACE/ace/README +++ b/ACE/ace/README @@ -366,8 +366,6 @@ ACE_HAS_THR_MINSTACK Platform calls thr_minstack() (e.g., Tandem).
