Common C++ Library NEWS -- history of visible user changes. 2000-05-22
This is a reorganized release that has been created as an intermediary
release to Common C++ 2.0. Includes sources reorganized into a single
working directory source directory and merged from the split sources for
win32, posix, and common that we used to do. It also includes the new
Common C++ template library and namespace support.
Some basic changes have been made to start the migration to Common C++
2.0. Those changes possible within the current 1.x framework have
been completed, including using inherited exception control, new UDP
socket pairings for supporting RTP directly, and other subtle changes
to many Common C++ class hierarchies.
The most interesting change is the introduction of doxygen as the standard
documentation tool for Common C++, thanks to Samoylov Olieg. This should
elminiate difficulties for windows users at the same time. Currently, a
Doxyfile set exists for posix documentation, and a win32 specific Doxywin32
may be added later.
In some ways this is the first "fully modern" Common C++ release. A lot of
work has already been put into making Common C++ updated with the most
current C++ coding practices while retaining full backward compatibility.
A number of inconsistancies have been found and fixed in the code during
this process. Also, much work has gone into making the Win32 source tree
functional and more current with the Posix source tree.
Perhaps the most visible changes are that a lot of work has gone into
making Common C++ code generally more portable, and specifically into
adding Unixware support which we are now able to test compile here. Also,
polling support has been introduced into the services modules, and this
has altered the size of the SocketPort and SerialPort classes.
Finally, we are doing most of our target testing with cross compilers now,
and some further work has been done in supporting cross compiler builds.
Several bugs related to building under Solaris have been fixed. In
addition, a major bug in DSO support was found whereby loading more
than one DSO would crash.
With this release, the Common C++ project has become part of the
GNU project. This release saw the introduction of a proper overview
document, as well as special handling for the "namespace.h" header
improved, and the Common C++ library split between Common C++ proper and
Common C++ "extras". Experimental and incomplete Common C++ frameworks
are found in the new "extras" package.
A large effort was put into cleaning up the Win32 source tree. We are now
able to compile all of win32 cleanly using mingw32 under GNU/Linux, as
well as most of "common". Currently the Bayonne "script" engine cannot be
compiled under win32 successfully since no "slog" has been defined for
win32 as of yet.
In addition, a number of minor supporting functions were found to be
nessisary and were added due to continuing work on the Bayonne IVR
engine. This release should sychronize Common C++ and Bayonne IVR
The most important change in the 0.9.6 release is that the entire "File"
class hierarchy has finally been rewritten. This new hierarchy is based
on "RandomFile" and is clearly and more clearly designed for physical
block and record oriented I/O and hence clearly seperate from "streaming".
Another major change is in the MappedFile class which now allows
arbitrary remapping of multiple segments of a file and uses mutex locks
for concurrent access control.
After a long delay, release 0.9.5 is here. It includes support for cleanly
cross-compiling solaris targets, and offers "rwlock" based ThreadLock as a new
sychronization object. This release also offers a first cut of the new Bayonne
state/event scripting engine classes. The Bayonne engine allows one to create an
embedded class extensible scripting engine for C++ applications.
With release 0.9.4, new support has been created in posix for using the
syslog facility and fifo stream I/O in Common C++. A lot of fixups were
done related to streaming and the win32 tree.
With release 0.9.2 of the newly merged Common C++ APE libraries, support
has been added for C++ "stream" driven serial I/O. Serial I/O classes
support single threaded streams, thread driven serial streams, and serial
ports managed through pooled service threads. This support now exists in
the Posix source tree, and will be added to win32 very soon.
With this declaration, the APE project, a Portable C++ Environment,
(http://www.voxilla.org/projects/projape.html>, formally and publicly
announces it's merger with the Common C++ project as currently hosted on
Source Forge. With this declaration, the following is announced:
1. A new, combined GPL licensed project, retaining the name 'Common C++',
a portable application framework, has been formed. This new project will
be licensed under the same terms and conditions as APE is today.
2. All existing Common C++ source files are now held in copyright of the
Open Source Telecomm Corporation (http://www.ostel.com) along with APE.
3. The new Common C++ project will retain and be developed from the
existing "1.2.3" release of APE. APE will be expanded to include the
Common C++ persistence engine, math, and html libraries. All work
related to future releases of APE will be derived from the new Common C++
APE code base and will also retain the Common C++ name in the future.
4. APE, renamed Common C++, will remain a true cross platform C++ class
framework and APE portability will be extended to all previous Common C++
5. The existing Common C++ SourceForge development and cvs areas will
be retained for use by the new combined project. Common C++ is an openly
developed project and continues to welcome outside contributors.
In announcing this merger, we believe we can better serve the open source
community at large, and the C++ application development community
specifically. In selecting to continue the Common C++ name going
forward, we believe we are better able to identify the project as a
general purpose C++ framework.
