Remove various dependencies on dictionary order in the standard library
tests, and one (clearly an oversight, potentially critical) in the
standard library itself - base64.py.
Remaining open issues:
* test_extcall is an output test, messy to make robust
* tarfile.py has a potential bug here, but I'm not familiar
enough with this code. Filed in as SF bug #1496501.
* urllib2.HTTPPasswordMgr() returns a random result if there is more
than one matching root path. I'm asking python-dev for
clarification...
This fixes 15 spurious test failures on Windows (probably all due to
the test leaving a wrong path in sys.argv[0], which then prevented
regrtest.py from finding the expected-output files for tests running
after test_optparse).
* add expansion of default values in help text: the string
"%default" in an option's help string is expanded to str() of
that option's default value, or "none" if no default value.
* bug #955889: option default values that happen to be strings are
now processed in the same way as values from the command line; this
allows generation of nicer help when using custom types. Can
be disabled with parser.set_process_default_values(False).
* bug #960515: don't crash when generating help for callback
options that specify 'type', but not 'dest' or 'metavar'.
* feature #815264: change the default help format for short options
that take an argument from e.g. "-oARG" to "-o ARG"; add
set_short_opt_delimiter() and set_long_opt_delimiter() methods to
HelpFormatter to allow (slight) customization of the formatting.
* patch #736940: internationalize Optik: all built-in user-
targeted literal strings are passed through gettext.gettext(). (If
you want translations (.po files), they're not included with Python
-- you'll find them in the Optik source distribution from
http://optik.sourceforge.net/ .)
* bug #878453: respect $COLUMNS environment variable for
wrapping help output.
* feature #988122: expand "%prog" in the 'description' passed
to OptionParser, just like in the 'usage' and 'version' strings.
(This is *not* done in the 'description' passed to OptionGroup.)
and test_support.run_classtests() into run_unittest()
and use it wherever possible.
Also don't use "from test.test_support import ...", but
"from test import test_support" in a few spots.
From SF patch #662807.
