Hi
We are happy to announce a new beta of ACE-5.3.5, TAO-1.3.5 and
CIAO-0.3.5. This beta comes with new ORB level services that were
developed over the past few months by folks at Washington University
and University of Rhode Island. Please see the release notes attached
with this email for more information.
As usual the latest release is available at:
http://deuce.doc.wustl.edu/Download.html
The doxygen documentation for the beta will be updated in the next few
hours!
We highly encourage you to download the present beta and use it with
your applications and let us know if there are any problems. As
always, please use the:
$ACE_ROOT/PROBLEM-REPORT-FORM
$TAO_ROOT/PROBLEM-REPORT-FORM
$CIAO_ROOT/PROBLEM-REPORT-FORM
so that we have the version/platform/compiler/options you're using to
report problems. We would also request that you take a look at
$TAO_ROOT/docs/releasenotes
$CIAO_ROOT/docs/releasenote.html
for the status of various ongoing projects at the doc groups of WashU,
UCI and Vanderbilt to move ACE+TAO+CIAO forward.
In addition the following is a list of noteworthy changes since the last
beta. Please refer to the ChangeLog for more details on the problem
and the nature of fixes applied.
---------------------------------------------------------------
IMPORTANT INFORMATION FOR UNIX and LINUX USERS
==============================================
Please note that $ACE_ROOT/lib directory also has to be added to
the LD_LIBRARY_PATH environment variable in addition to the
existing $ACE_ROOT/ace. This is part of the transition plan to
accomodate and use Makefiles generated from MPC.
ACE
====
. Added support for the new CBuilderX Preview compiler and improved
support for the MingW compiler.
. The use of shared library versioning is now controlled by the
versioned_so make variable, which can be set on the command line
or in your platform_macros.GNU file. versioned_so=1 turns on
versioning, and versioned_so=0 turns it off. The default varies
by platform. The version number applied to the library is
controlled by the SOVERSION make variable. This can be set to
any value you like. The default is <ACE-major>.<ACE-minor>.<ACE-beta>.
. The limitation of the user level notification queue within the
Select_Reactor and TP_Reactor has been fixed. This problem
prevented applications from having unbounded queue of notification
messages. [BUG 1268]
. Added support for allocators inside the Kokyu dispatching
infrastructure.
. An initial implementation of thread scheduling and dispatching
mechanisms to support Distributable Threads in Dynamic Scheduling
Real Time CORBA (DSRTCORBA) has been added to the Kokyu
infrastructure ($ACE_ROOT/Kokyu). Two different styles of
dispatching mechanisms are available - Condition variable based
dispatching and OS-based direct dispatching. The DSRT dispatching
module in Kokyu is flexible enough to plug in different kinds of
scheduling policies. For more information, please see
$ACE_ROOT/Kokyu/docs/Kokyu.html.
. Improved support for LynxOS
TAO
=====
ORB
----
. Added CORBALOC support for SCTP.
TAO SSLIOP Pluggable Protocol
-----------------------------
. Removed erroneous HPUX-specific check from TAO_SSLIOP Makefile.
TAO_SSLIOP should build properly on HP-UX.
ORB services
------------
. Fixed a bug in the naming service which caused a wrong corbaname
ObjectURL generation [BUG 1606]
. Implementation of the Real-Time CORBA 1.0 Scheduling Service,
implemented by Real-Time Distributed Object Computig Lab at
University of Rhode Island is now available in this beta. The
RTCosScheduler allows applications to schedule tasks according to
scheduling information determined a priori. This scheduling
information is stored in a config file so that both the client and
the server has access to it. For more information, please see
$TAO_ROOT/docs/releasenotes/rtc10_sched.html.
. The FaultTolerance library is now split into three different
libraries viz. Utils, Client and Server. These finer granular
pieces are available to the applications if the Makefiles are
generated using MPC. Using the old Makefiles and dsp files would
still generate a single library for backward copatibility.
. Support for Fault Tolerance in the TAO Real Time Event Service.
This allows you to start several event services in different
machines. These event services form an object group which
can be treated as a logical event service by clients. The clients
only communicate with the primary (leader) of the object group.
The other event channels in the object group are called backups.
Once the primary dies, one of the backups will assume the
reponsibility of primary and this process is transparent to the
clients. For more information, see
$TAO_ROOT/docs/releasenotes/ftrt_ec.html
. Support for Stream Control Transmission Protocol (SCTP) in the
AVStreams pluggable protocol. This allows users to choose SCTP
as their transport protocol to send and receive data. The SCTP
protocol is available only when the sctp flag is set in
$ACE_ROOT/include/makeinclude/platform_macros.GNU.
. Example implementations of DSRTCORBA schedulers using Kokyu are
available in $TAO_ROOT/examples/Kokyu_dsrt_schedulers. Currently,
there are three schedulers - Maximum Importance First, Fixed
Priority and Maximum Urgency First.
. Fixed problem in CPU load monitor that prevent loads from being
gathered on Linux. Fixed problem where it wasn't possible to
retrieve a CPU load monitor object reference from the LoadManager.
. Additional tests and performance-tests for LoadBalancer have been
added.
CIAO
====
. CIDL compiler now supports all the basic types in the front end
and back end.
. The CIDL compiler has some Makefiles and vcproj files for
compilation. MPC support for the CIDL compiler is just round the
corner.
Bugs Fixed or Resolved
======================
1268, 1585, 1588, 1590, 1606, 1609, 1610, 1612, 1614
Issues
======
. The generated code for the supports keyword in IDL doesn't generate
the right code.
Thanks
