The reason that we aren't going to document how to build STAF on Python
2.7 yet is because we'll most likely be adding new environment variables
to support for Python 2.7 when we implement the feature to provide support
for Python 2.7 such as the following (instead of how you built it):
PYTHON_BUILD_V27
PYTHON_V27_ROOT
PYTHON_V27_INCLUDEDIRS
PYTHON_V27_LIBDIRS
PYTHON_V27_LIBS
Hopefully, we'll be able to provide this support soon. Thanks for your
input.

Thanks for the reply. My answers are embedded below.

Hi Semih,
Here are the answers to your questions/requests:
a) Could Python 2.7 support be added and made as the default Python
version to use instead of 2.2?
Most new Python development activity will use 2.7 or 3.1 branches.
Please open a STAF feature request to add support for Python 2.7 (which
was just released on July 3rd, 2010). There already is a feature request
open for adding support for Python 3.x (#2981028) at
http://sourceforge.net/tracker/?func=detail&aid=2981028&group_id=33142&atid=407384
and we hope to start work on this feature in the next couple of months.
Please add a comment to this feature request that you need STAF Support
for Python 3.1 and why (this helps us in prioritizing work on features).
Thanks.
SSC: Thanks for pointing that out. I put following comments there:
?Most new (Python) development will continue on 3.1.X branch whereas 2.7
branch somewhat entered into extended maintenance mode. Version 2.7 also
backported some of 3.1.X's features as well. Some of these features are
highly beneficial in testing scenarios such as operations on sets, tuples,
comprehensions, printing, formatting , shuffling and different kind of
numbers (decimal, etc). As a developer I want to be able to access these
newer features in test scenarios and I don't want STAF to be a limiting
factor.?
Even though most new Python development activity in your company will use
Python 2.7 or 3.1, there are many existing companies and test teams that
use older versions of Python. So, determining a default version of Python
that makes everyone happy is not possible (though admittedly, Python 2.2
is quite old). Also, changing the default Python version can "break"
existing tests. That's why there are options to choose the version of
Python support you want as the default during installation. There's even
an option to have STAF select the Python version that's in your PATH.
SC: What I meant that building STAF from source with v2.7 support as I did
with some tricks. Obviously STAF 3.4.2 and Python 2.7 works ok, why not
update the documentation that new STAF users can select version of their
choice? Of course binary STAF builds should support and cater for existing
STAF user base.
b) Can the documentation of STAF be updated (regarding Python support)?
Did you mean updates to building Python 2.7 support in the STAF
Developer's Guide? Yes, as part of the work that will be done for the
STAF feature request you open for providing STAF support for Python 2.7,
we'll be sure to update the documentation as needed. Thank you for your
input on what worked for you to build STAF support for Python 2.7 on
OpenSolaris. Note that once the STAF binaries provide support for STAF
Python 2.7, most people will be using the support provided by STAF, not
building Python support themselves.
SC: I mean if you follow the steps (setting environment variables) as
stated in the developers guide, one cannot build STAF-Python support since
the STAF makefiles cannot pick correct include and library directories.
Please refer to my initial post for extra variables need, which I
extracted by reading makefiles.
c) If errors reported by TestPython.py are not genuine, can they be
disabled in the source tree? It is confusing for STAF users.
These errors in the removePrivacyDelimiters tests in TestPython.py only
occur on certain platforms, in certain runs. We're not sure why yet.
Please open a bug open regarding these errors (as I couldn't find an open
bug for this). Note that as most people do not build Python themselves,
they do not run TestPython.py. So, fixing this bug has not been a top
priority. Also, these errors do not always occur. But, of course, we
want to resolve them.
d) Lastly, is there any plan to support Python STAF services? (That is
being able to write STAF services in Python). Has anyone attempted this in
the past? Is there any code fragments available from the STAF community?
Yes, there is a feature open (#1432391) to support writing STAF services
in Python and work has begun and there are files attached to the feature
that contain support for Python STAF services with some bugs still to be
worked out. If you are interested in working on this feature, let us
know. For more information, see
http://sourceforge.net/tracker/?func=detail&aid=1432391&group_id=33142&atid=407384
.
SC: Thanks for pointing that out. I?m interested in this feature, and will
try out the code posted in that ticket.

[staf-users] STAF + Python issues
Hi,
I believe "Building STAF Python Support" section in STAF Developer's
Guide is incomplete:
http://staf.sourceforge.net/current/stafdg.html#Header_buildPython
I could only build STAF Python support with following environment settings
(not just the ones listed above document):
# For building Python support
# OpenSolaris 2009.06, Sun CC 5.10, STAF 3.4.2, Python 2.7
#export PROJECTS=python
export PYTHON_ROOT=/stow/python-2.7
export PYTHON_INCLUDEDIRS=$PYTHON_ROOT/include/python2.7
export PYTHON_LIBDIRS=$PYTHON_ROOT/lib
export PYTHON_LIBS=python2.7
export PYTHON_BUILD_V22=0
export PYTHON_BUILD_V23=0
export PYTHON_BUILD_V24=0
export PYTHON_BUILD_V25=0
export PYTHON_BUILD_V26=1
export PYTHON_V26_ROOT=$PYTHON_ROOT
export PYTHON_V26_INCLUDEDIRS=$PYTHON_INCLUDEDIRS
export PYTHON_V26_LIBDIRS=$PYTHON_LIBDIRS
export PYTHON_V26_LIBS=$PYTHON_LIBS
In addition, TestPython.py reports following errors (which was also
reported on 4 Feb 2010):
$ python TestPython.py |grep ERROR
ERROR: removePrivacyDelimiters(!...@^^!!@a...@!!^^!!@b...@!!, 1) !=
^...@a@!!...@b@!!
ERROR: removePrivacyDelimiters(!...@^^!!@a...@!!^^!!@b...@!!, 0) !=
^...@a@!!...@b@!!
ERROR: removePrivacyDelimiters(!...@^@!!a...@b^@!!, 1) != @!!...@b@!!
ERROR: removePrivacyDelimiters(!...@^@!!a...@b^@!!, 0) != @!!...@b@!!
*** ERROR: 4 tests failed ***
I have following questions/requests to STAF development team:
a) Could Python 2.7 support be added and made as the default Python
version to use instead of 2.2?
Most new Python development activity will use 2.7 or 3.1 branches.
b) Can the documentation of STAF be updated (regarding Python support)?
c) If errors reported by TestPython.py are not genuine, can they be
