ACE VERSION: 6.3.0
HOST MACHINE and OPERATING SYSTEM:
Centos 6.7 and Linux kernel 2.6.32-573.12.1.el6.i686
CONTENTS OF $ACE_ROOT/bin/MakeProjectCreator/config/default.features
no such file
AREA/CLASS/EXAMPLE AFFECTED: no
DOES THE PROBLEM AFFECT:
On Unix systems, did you run make realclean first? Yes, I did.
Using ACE Proactor AIO framework on network sockets to exchange
messages between two or more endpoints on linux OS. It looked the message
read or write blocked or in order.
I am porting an application into Linux which utilizes ACE
proactor AIO framework for a network communication ( read/ write socket ).
It works fine on Windows OS. However, on Linux, The application looked like
exchange messages in order, for example, When I tried to send a message to
the peer, I found that ACE_POSIX_AIOCB_Proactor did invoke aio_write() but
the message did not get sent out util the peer sent a message out, and then
got that previous message in. More worse, most time, when the connector
estalished a connection and tried to send the first message, the system got
locked up because a read operation probably be put before write
operation for listening any incoming messages.
I searched the issue and found the similar issue report in the
link but it was several years age:
Is it still the limitation on Linux? Is there any way to get the
ACE Proactor AIO work for network communication ( exchange message via
socket with full duplex) now? Any help would be greatly appreciated
