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)?
