[PATCH] Add script to compile different versions of python; add python syntax checker

Hello!

Because my last patch [1] had some problems running under python-2.3 
(and it looks, that I'm not the only one having this problem [2] [3]), I
wrote some scripts which compile different versions of python.
Additionally these scripts do a syntax check of all python code using
these different python versions.
This patch makes it easy to test the python code for different versions of
python: only the LD_LIBRATY_PATH and PATH must be adapted.
Currently supported: 2.3.7, 2.4.6, 2.5.4, 2.6.2, 3.1

Please consult the 'tests/README' how to use. (It's mostly a 'cd tests
&& make').

Kind regards

Andreas Florath

P.S.: First results:
Compiling
../tools/xm-test/tests/block-create/10_block_attach_dettach_multiple_devices.py
...
  File
"../tools/xm-test/tests/block-create/10_block_attach_dettach_multiple_devices.py",
line 10
    from os import path.basename
                       ^
SyntaxError: invalid syntax

for all versions of python. (Even after fixing this syntax error, there
is at least another one.) Sorry, but currently I'm not able to send a
patch for this, because I have major problems running the xm-test suite.

N.B.: Second result: python-3.1 does not work at the moment (227 Syntax
errors, mostly all because of the 'print arg' vs. 'print(arg)', and
'except Exception, e:' vs. 'except Exception as e:'). It looks that it
might be possible to fix all the 'print's - but the new exception syntax
is only implemented in python 2.6 (and AFAIK not in 2.3, 2.4 or 2.5).

Hello Community,
Hello Keir,

just recognised that the patch was applied - but the directory is now
different from the original.  This breaks the Makefile and the provided
scripts.

I'll send a patch against the current tip this evening.

Kind regards

Ah, I just assumed it would all be relative to the directory it's resident
in. Of course XEN_ROOT does need fixing (I forgot about that), but then you
can make yourself a local-dir variable based directly on $(PWD) rather than
$(XEN_ROOT).

Also, at the same time it would be good if you would replace ${} make
variable expansions with $(). It's purely a style consistency thing, as we
use the latter in all other Makefiles.

 Thanks,
 Keir

Hello!

The move breaks some paths and scripts.  The applied patch fixes them.

Additional changes:

o scripts and Makefile are mostly location independent now
  (exception XEN_ROOT in Makefile)
o use of $() instead of ${} in Makefile

Kind regards
