[ace-users] I got some strange problems with ACE on linux(ubuntu 7.04)

[Douglas C. Schmidt]

Hi,

Thanks for using the PRF.

>    ACE VERSION: 5.5

ACE 5.5 is old, so please upgrade to ACE+TAO+CIAO x.5.8 (i.e., ACE
5.5.8, TAO 1.5.8, and CIAO 0.5.8), which you can download from

http://download.dre.vanderbilt.edu

under the heading: "Latest Beta Kit".

The DOC groups at Washington University, UC Irvine, and Vanderbilt
University only provide "best effort" support for non-sponsors for the
latest release, as described in

http://www.dre.vanderbilt.edu/~schmidt/DOC_ROOT/ACE/docs/ACE-bug-process.html

Thus, if you need more "predictable" help for earlier versions of
ACE+TAO, I recommend that you check out

http://www.dre.vanderbilt.edu/support.html

for a list of companies that will provide you with ACE+TAO commercial
support.

Thanks,

        Doug

>    SYNOPSIS:
>      ACE_Reactor does not "react" after one client disconnect from

>    DESCRIPTION:
>      I wrote some programs (one server and some clients) on windows
>xp(vs2005). I want to deploy them on linux.
>      I compile the server program on ubuntu 7.04 and run it

>every request from other client. other clients can connect to server
>but can't send data. the ACE_SOCK_Stream.send() block there. No
>handle_input() of ACE_Event_Handler that registered to ACE_Reactor
>will be invoked.
>
>      When one client disconnect from server, I make the
>handle_input() of the ACE_Event_Handler for this client peer return
>-1. Then the handle_close() will be invoked, in which I release the
>resources.

>      Everything goes correctly on windows.
