From ab2229451827f530959d554920619d87daa34586 Mon Sep 17 00:00:00 2001

Subject: [PATCH] test: make Python files supported _also_ with Python 3.3+
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
- use "print" like a function rather than a statement
. where implicit newline is to be suppressed, don't do that
and rather strip it from the string to be printed instead
- use 2+3 compatible convention for parametrizing exceptions
- Python 3 doesn't recognize "basestring" class, and at the place
of use (pre Python 2.7 only), unicode string is really not expected
(also re.UNICODE flag is not used...)
- Python 3 doesn't recognize "xrange" function, but the surrounding
code can be reasonably simplified using "enumerate" function
- arrange dict treatment in a compatible way:
. d.has_key(k) -> k in d
. d.iteritems() -> custom "iter_items", always efficient wrapper
. d.iterkeys(), here incl. lazy mapping and filtering
-> rewrite while retaining laziness
. optimize UT.merge_dicts in script/unit-test.py along
- also in three instances, deal with string/uninterpreted bytes proper
dichotomy introduced in Python 3, and related to that, "string"
module only supports "ascii_lowercase" attribute in Python 3
(as opposed to system-specific plain "lowercase" one)
Note that script/unit-test.py has a pre-existing issue (regardless
of which Python version interpreter is used), so at least document
that in the header for now.
