[PATCH v2 0/7] perf script python: add Python3 support

[Tony Jones]

This is v2 of my version of the patchset.  Incorporating the 
previous feedback.  Some changes from v1 were already merged.

Patch 1/7 deals with the existing inconsistent indentation.
Indentation is now consistent per file but varying styles (tabs,
4 spaces and 8 spaces).   
I will followup at a later date with changes to checkpatch to ensure
that the syntax per file is maintained.

Patches 2/7 through 5/7 were sent in v1,  they have been changed 
to remove the previous indentation changes

Patch 6/7 was sent in v1.  I had previously *not* been able to test 
export-to-postgresql.py.  I was able to do so this time and found
that more changes were needed.    The author of the original code
seems concerned about code-style so I would suggest you only merge 
with his explicit ACK.

Patch 7/7 was not in v1, it cleans up some repeated use of date
functions in the SQL exporters.  It is not mandatory for Python3
support.  It is dependent on Patch#6.

I hope I've got everything correct, I've retested until I feel I 
can't look at Python code anymore for a while :-). Hopefully I've 
not made any more mistakes.  If I have, please LMK and I'll do v3.

Thanks

Tony
