[ace-users] ACE/TAO/CIAO/DAnCE x.1.4 available for download

Hi all,

Once again, thanks to the efforts of many developers, testers, and
users, we are pleased to announce the micro and bug fix only release
of ACE 6.1.4, TAO 2.1.4, CIAO 1.1.4, and DAnCE 1.1.4, which is available
from the usual download location at:


under the heading "Latest Micro Release Kit".

The doxygen documentation for this release is also available.  In
addition to the packages combined of sources and generate makefiles,
this release provides source-only packages for developers who use MPC to
generate their own makefiles.

We encourage you to download the new release, use it with your
applications, and let us know if you encounter any problems. Please use the:


so that we have the proper version/platform/compiler/options you're
using to report problems. We also request that you take a look at:


for the status of various ongoing projects at the DOC group of
Vanderbilt to move ACE+TAO+CIAO+DAnCE forward.  Overviews of our recent
progress and upcoming plans are available at:


The overall success rates for the test results gathered from all our
daily builds is 97% for the ACE tests and 96% for the TAO, CIAO,
and DAnCE tests.

Please see:


for a summary of these tests.  As always, we appreciate your help in
resolving any remaining problems. Please see:


for an overview of our bug fixing policies.  Moreover, please see:

The following is a list of key changes since the last major release.
Please refer to the corresponding ChangeLog files, NEWS files, or
Bugzilla entries for more details on the problem and the nature of fixes

Changes to ACE

.. Added a new ACE_Time_Value derived template class (Time_Value_T.h):

   template <class TIME_POLICY> class ACE_Time_Value_T

   This template class overloads 4 new virtual methods from
   the ACE_Time_Value base class to provide time policy aware
   time values:
   to_relative_time ()
   to_absolute_time ()
   now ()
   duplicate ()

.. Updated time policy classes to return ACE_Time_Value_T<>
   instantiations for the corresponding time policy instead of 'common'
   time values.

.. Added new ACE_Monotonic_Time_Policy (Monotonic_Time_Policy.h).
   This class provides a monotonic time source for supported
   platforms (Windows and POSIX platforms providing the required
   clock_gettime() time source; currently verified for Windows and

.. Updated OS_NS_Thread to use the new time policy support in
   ACE_Time_Value for (relative) time calculations and added new
   ACE_OS::condattr_setclock ()  method.

.. Added TIME_POLICY support to ACE_Condition_Attributes to allow for
   monotonic timer support for ACE_Condition.

.. Added TIME_POLICY support to ACE_Message_Queue-s, ACE_Task-s and
   related classes to enable support for monotonic timers in the timed
   wait methods (ACE_Condition based). See docs/ACE-monotonic-timer.html
   for how to use this.

.. Added two new regression tests:
   and updated the Bug_4055_Regression_Test to a fixed state.

Changes to TAO

.. CORBA::string_dup() and CORBA::string_free() have been enhanced to use
   non-allocated and shared static null strings. This allows for
   optimized default null string initialization in CORBA string members
   and a reduction in redundant dynamic memory management required for
   such. This enhancement can be removed via the config.h by including

   NOTE that it is a (CORBA spec) requirement that all CORBA::strings are
   deleted via the CORBA::string_free() and allocated via the
   CORBA::string_dup() or CORBA::string_alloc() calls; you must not use
   the c++ keywords new and delete[] directly. Previously it was
   possible to ignore this requirement, however if you do so now, this
   enhancement for null strings will catch you out, as deleting these
   null CORBA::strings will cause corrupt heap and/or segfaults.

.. Add support for -ORBPreferredInterfaces option to UIPMC. The form
   follows the same pattern as IIOP for IPv4 i.e. a local interface IP
   address should be specified as the mapping. e.g.
   -ORBPreferredInterfaces 225.*= For IPv6 the preferred
   interface should (neccessarily) be set as an interface name (e.g.
   'eth0' for linux, or 'Loopback Pseudo-Interface' on windows) or an
   interface index number on windows. e.g. -ORBPreferredInterfaces
   FF01:*=eth0. Also add support an -ORBListenOnAll 0|1 UIPMCFactory
   option that can be specified in the svc.conf to make the acceptor
   listen on all multicast enabled interfaces on platforms that this is
   not the default. This has been observed to be required for the
   UIPMCAcceptor to open on the most recent Linux distribs.

   NOTE that there is an obvious elephant in the room in testing this
   option, we can't rely on any build/test machine having more than one
   (or any?) interfaces so the test (TAO/orbsvcs/tests
   /Miop/McastPreferredInterfaces), such as it is, is relying on side
   effects which may not hold for all platforms. Additionally the IPv6
   behaviour isn't even consistent across platforms and the build
   machines can't be relied upon to have a 'proper' (non-zero conf link
   local) IPv6 configuration. Basically, if you want some confidence
   this is actually working I'd advise testing this option before you
   use it, running it on a machine with multiple interfaces with the
   debug level turned up.

.. Enhanced the MIOP implementation; this protocol now supports MIOP
   message fragmentation which is controlled via the new
   MIOP_Strategy_Factory. For details see the MIOP_Strategy_Factory
   section in the docs/Options.html document included with this

Changes to CIAO

.. The CIAO DDS4CCM integration with OpenDDS has been reworked in a way
   that OpenDDS doesn't know anything anymore from CIAO. In order to use
   DDS4CCM with OpenDDS you need OpenDDS 3.3 or higher.

Changes to DAnCE

.. None
