1.  Introduction


1.1  Preface
These release notes accompany TETware Release 3.5.

TETware includes all of the functionality of the Test Environment Toolkit
Release 1.10 (TET), the Distributed Test Environment Toolkit Version 2
Release 2.3 (dTET2) and the Extended Test Environment Toolkit Release 1.10.3
(ETET), together with a number of new features.

There are two principle versions of TETware.  One version is known as
Distributed TETware.  This version uses a client-server architecture and
provides support for processing local, remote and distributed test cases.  The
other version is known as TETware-Lite.  This version does not use a client-
server architecture or require a network transport.  It is more simple to set
up than is Distributed TETware but does not provide support for the processing
of remote or distributed test cases.

Distributed TETware is implemented on UNIX operating systems and also on the
Windows NT operating system.  TETware-Lite is implemented on UNIX operating
systems and also on the Windows NT and Windows 95 operating systems.

Throughout this document, the Windows NT and Windows 95 operating systems are
referred to collectively as Win32 systems.  The individual system names are
only used when it is necessary to distinguish between them.


1.2  Audience
This document is intended to be read by software engineers and/or systems
administrators who will install TETware on their computer systems.  A
knowledge of system administration is assumed when TETware installation and
configuration instructions are presented.  In addition, a knowledge of network
administration is assumed when TETware is to be built to use network
transports.


1.3  Conventions used in this document
The following typographic conventions are used throughout this document:

   + Courier font is used for function and program names, literals and file
     names.  Examples and computer-generated output are also presented in this
     font.

   + The names of variables are presented in italic font.  You should
     substitute the variable's value when typing a command that contains a
     word in this font.

   + Bold font is used for headings and for emphasis.




                                                                        Page 1

distribution.

1.5  Problem reporting

If you have subscribed to TETware support and you encounter problems when
building or executing TETware you should take a copy of the error reporting
template contained in the file tet-root/doc/tet3/err.template in the
distribution, fill in the details of the problem, and send it by electronic
mail to:

     tet_support@opengroup.org

Alternately you may use a web browser to complete and submit the HTML form
included in the file tet-root/doc/tet3/errtemp.html in the distribution.

You should include sufficient information in your report to enable someone who
is unfamiliar with your system to be of assistance in solving the problem.

Users are reminded that the user-contributed software which accompanies the
TETware distribution is not covered by TETware support services.


2.  New features in this release

The following features appear for the first time in this release of TETware:

   + A version of the tccd bootstrap program which runs as a Windows NT
     service has been provided.  The name of this program is tccdsrv.  This
     program is provided mainly for use by GUI-based TETware installation
     tools, but may also be executed from a command prompt.  It is described
     in a manual page at the back of the TETware User Guide.

   + Support for Solaris 8 has been added to the configuration script.  This
     uses the same defines.mk file as is used for Solaris 7.




                                                           10th September 2000








                                                                   TET3-RN-3.5



   + Some minor revisions have been made to the documentation.


3.  Status of this release

This release of TETware is a general release for production use.


4.  Problems fixed since the last release

The following problems have been fixed since the last TETware release:

   + When tcc received a SIGHUP or SIGTERM signal while processing a remote or
     distributed test case with output capture mode in effect, this could
     result in an ``Assertion failed'' error message.

   + If a C library function does not set errno after an error occurs, the API
     error handler would print an unhelpful error message if the problem
     occurred on a remote system.  This problem occured on Win32 systems where
     some of the C runtime support library's stdio functions (at least) do not
     set errno when an error occurs.

   + On UNIX systems, the journal context number was not updated in a
     subprogram launched by a call to tet_remexec().

   + When a multi-threaded test case created and joined several threads in a
     particular test purpose function on a system where the POSIX thread
     implementation re-uses a thread ID as soon as it is freed, the API's
     thread table could become corrupted.

   + The file src/tet3/tcc/ynstr.c contained calls to exit() but did not
     include <stdlib.h>.  This could cause a compile-time error on certain
     systems.


5.  Known problems in this release

There are no known problems in this release.


6.  Building and installing TETware


6.1  Building and installation instructions
For information on how to build and install TETware, please following the
instructions in the version of the TETware Installation Guide which is
appropriate for your system.

Note:  In this release the Java API is supported for use with JDK Version 1.1
      on Solaris, Linux and Win32 systems.  In order to build the Java API on
      these systems a variable must be set in the defines.mk file which


                                                                        Page 3








                                                      Test Environment Toolkit
                                         Release Notes for TETware Release 3.5


      specifies where the Java Development Kit (JDK) has been installed on
      your machine.

      On Solaris Releases 7 and 8 the JDK is supplied with the operating
      system and so is installed in a standard place (/usr/java).  This
      location is specified in the defines.mk file for Solaris 7 that is
      supplied in the distribution.

      However, on other machines the JDK might be installed anywhere, so it is
      necessary to customise your defines.mk file if you want to build the
      Java API.  Refer to the section entitled ``Support for Java'' in the
      TETware Installation Guide for instructions on how to do this.

6.2  Installed platforms


6.2.1  UNIX systems
Both TETware-Lite and Distributed TETware versions have been installed and
tested on the following platforms:

   + AIX Release 4.3.1 using c89

   + HP-UX Release 11.00

   + Linux version 2.2.16 (Slackware) using gcc version egcs-2.91.66 and glibc

   + Solaris Release 8 using the Sun Workshop Compiler

   + UNIX System V Release 4

   + UnixWare Release 2.1.1


6.2.2  Win32 systems
TETware-Lite and Distributed TETware have been installed and tested on Intel
PCs running Windows NT release 4.0.

TETware-Lite has been installed and tested on Intel PCs running Windows 95.


6.3  API status

6.3.1  Thread-safe APIs

The Thread-safe APIs have been exercised on the following platforms:

   + Linux using POSIX threads

   + Solaris using POSIX threads and UI threads




                                                           10th September 2000








                                                                   TET3-RN-3.5



   + UnixWare using UI threads

   + Win32 systems

The following behaviour has been observed when using the Thread-safe API on
UnixWare:

  i.  A call to tet_printf() in a non-main thread causes the process to
      receive a SIGSEGV signal.

 ii.  Cleanup of left-over threads sometimes causes a fatal error.

It is believed that this behaviour may be due to a problem with the threads
implementation on this platform.

On Win32 systems the thread-safe APIs must be used with the multi-threaded DLL
version of the C runtime support library.  Use with the multi-threaded static
version of the C runtime support library is not supported.

6.3.2  C++

The C++ APIs have been exercised on Linux, Solaris, UnixWare and Win32
systems.

6.3.3  Java

The Java API is only supported when used with JDK v1.1 on the following
platforms:

   + Linux using ``green'' threads

   + Solaris using native threads

   + Win32 systems

6.4  Transport-specific status


6.4.1  Socket network interface
Versions of Distributed TETware using the socket network interface have been
tested on all the platforms listed previously.


6.4.2  XTI network interface
Versions of Distributed TETware using the XTI network interface have been
tested on AIX 4.3, Solaris 2.7 and UnixWare 2.1.1 using TCP as the underlying
transport provider.

There is a known problem with some SVR4 XTI implementations in which the
t_sync() function does not work correctly.  An XTI implementation may hold
transport endpoint data either in kernel or in user address space.  The


                                                                        Page 5








                                                      Test Environment Toolkit
                                         Release Notes for TETware Release 3.5


t_sync() function is included in the XTI specification for the benefit of
implementations which do not automatically detect when the transport endpoint
data held in user space is lost.  Examples of when such loss might occur are
when the file descriptor underlying a transport endpoint is duplicated using
fcntl() or when the process address space is overlaid by one of the exec()
system calls.

Since the XTI version of TETware may perform both of these operations, it will
not function when used with an XTI implementation which does not automatically
detect the loss of data held in user address space and in which t_sync() does
not perform the advertised function.  A common symptom of this problem is when
one of the servers tetsyncd and tetxresd fails with a TBADQLEN error
associated with a t_listen() call soon after being started by tcc.

The XTI version of Distributed TETware has not been tested using an OSI
connection orientated transport provider.


7.  TETware for TET and ETET users

Some hints and tips for users experienced with previous TET implementations
are presented in an appendix to the TETware User Guide.
