Issue1565644

I installed latest HEAD installer from [1] to test it
with our software. When I started it for the first time
I noticed that it has the version number identical to
the previoud 2.2 alpha 1 release.

Jython 2.2a1 on java1.5.0_06 (JIT: null)
Type "copyright", "credits" or "license" for more
information.
>>> import sys
>>> sys.version
'2.2a1'
>>> sys.version_info
(2, 2, 0, 'alpha', 1)

Because there has been quite a lot of changes after the
latest release it would help our testing if this HEAD
version could have some other version (basically
anything different would be ok) so that we could add
version checks into the code and have different code
for different Jython versions. We, for example, have a
workaround for a unicode bug 1538001 [2] and now that
it's fixed in HEAD we should use different code when
using this version.

Not sure if the snapshots will grow into a common practice
for Jython, but note that cpython in 2.3 introduced a
'platform' module, and there is also patch to make it play
nicer with other python implementations:

 http://python.org/sf/1563842

Perhaps it would be handy in general to have this module
available in jython even in 2.2. Then at least one could use
 say platform.python_build as a differentiator.

'platform' module sounds like a great idea. Seeing the build
number would make recognizing the exact version pretty trivial.

Getting different result from sys.version and
sys.version_info in a snapshot than in the latest version
would still be nice. How CPython handling this?

Patch 198100: 1565644-patch.txt checked in.
Now testing.
It is in the nature of this patch that it has to be checked
in before real life tests are possible.

With patch 198102: 1565644-typo-patch.txt checked in,
snapshot builds can now be distinguished.

After a standalone installation, I got:
$ cd /stuff/temp/jython2950/
$ ls
jython.jar
$ java -jar jython.jar
Jython 2.2a2950 on java1.5.0_08 (JIT: null)
Type "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.version
'2.2a2950'
>>> sys.version_info
(2, 2, 0, 'snapshot', 2950)
>>> 

The 2950 snapshot build will be online soon.
