with default False for testmod(). The real point of introducing this was
so that output from doctest.master.summarize() would be the same as in
2.3, and doctest.master in 2.4 is a backward-compatability hack used only
by testmod().
- Template no longer inherits from unicode.
- SafeTemplate is removed. Now Templates have both a substitute() and a
safe_substitute() method, so we don't need separate classes. No more
__mod__() operator.
- Adopt Tim Peter's idea for giving Template a metaclass, which makes the
delimiter, the identifier pattern, or the entire pattern easy to override
and document, while retaining efficiency of class-time compilation of the
regexp.
- More informative ValueError messages which will help a user narrow down the
bogus delimiter to the line and column in the original string (helpful for
long triple quoted strings).
decoding incomplete input (when the input stream is temporarily exhausted).
codecs.StreamReader now implements buffering, which enables proper
readline support for the UTF-16 decoders. codecs.StreamReader.read()
has a new argument chars which specifies the number of characters to
return. codecs.StreamReader.readline() and codecs.StreamReader.readlines()
have a new argument keepends. Trailing "\n"s will be stripped from the lines
if keepends is false. Added C APIs PyUnicode_DecodeUTF8Stateful and
PyUnicode_DecodeUTF16Stateful.
SF patch #1015989
The basic idea of this patch is to compute lineno attributes for all AST nodes. The actual
implementation lead to a lot of restructing and code cleanup.
The generated AST nodes now have an optional lineno argument to constructor. Remove the
top-level asList(), since it didn't seem to serve any purpose. Add an __iter__ to ast nodes.
Use isinstance() instead of explicit type tests.
Change transformer to use the new lineno attribute, which replaces three lines of code with one.
Use universal newlines so that we can get rid of special-case code for line endings. Use
lookup_node() in a few more frequently called, but simple com_xxx methods(). Change string
exception to class exception.
Several functions adopted the strategy of altering a full lengthed
string copy and resizing afterwards. That would fail if the initial
string was short enough (0 or 1) to be interned. Interning precluded
the subsequent resizing operation.
The solution was to make sure the initial string was at least two
characters long.
Added tests to verify that all binascii functions do not crater when
given an empty string argument.
"all or none" to "all or some".
This provides much greater test coverage without eating much time.
It also makes it more likely that routine regression testing will
unearth bugs.

DocTestRunner.__run: Separate the determination of the example outcome
from reporting that outcome, to squash brittle code duplication and
excessive nesting.
this module imports itself explicitly from test (so the "file names"
current doctest synthesizes for examples don't vary depending on how
test_generators is run).
s.join([t]) is t
for (s, t) in (str, str), (unicode, unicode), and (str, unicode).
For (unicode, str), verify that it's *not* t (the result is promoted
to unicode instead). Also verify that when t is a subclass of str or
unicode that "the right thing" happens.
- Improvements to interactive debugging support:
- Changed the replacement pdb.set_trace to redirect stdout to the
real stdout *only* during interactive debugging; stdout from code
continues to go to the fake stdout.
- When the interactive debugger gets to the end of an example,
automatically continue.
- Use a replacement linecache.getlines that will return source lines
from doctest examples; this makes the source available to the
debugger for interactive debugging.
- In test_doctest, use a specialized _FakeOutput class instead of a
temporary file to fake stdin for the interactive interpreter.
and intervening text strings.
- Removed DocTestParser.get_program(): use script_from_examples()
instead.
- Fixed bug in DocTestParser._INDENT_RE
- Fixed bug in DocTestParser._min_indent
- Moved _want_comment() to the utility function section
actual output into lines created spurious empty lines at the ends of
each. Those matched, but the fancy diffs had surprising line counts (1
larger than expected), and tests kept having to slam <BLANKLINE> into the
expected output to account for this. Using the splitlines() string method
with keepends=True instead accomplishes what was intended directly.
