* Don't import 'ic' in webbrowser, that module is no longer used
* Remove 'MacOS' from the list of modules that should emit a Py3kWarning on import.
This is needed because one of the earlier tests triggers and import of this
extension, and that causes a failure in test_py3kwarn (running test_py3kwarn
separately worked fine)
With these changes 'make tests' no longer says that test_py3kwarn fails.
This revision introduced quoting for strings containing | based
on a misunderstanding of the commonly used quoting rules used
on Windows.
| is interpreted by cmd.exe, not by the MS C runtime argv initializer.
It only needs to be quoted if it is part of an argument passed through
cmd.exe.
See issue1300, issue7839, and issue8972.
The fix for issue 4050 caused a regression: before that fix, source
lines in the linecache would eventually be found by inspect. After the
fix inspect reports an error earlier, and the source isn't found.
The fix for the fix is to have getsourcefile look in the linecache for
the file and return the psuedo-filename if the source is there, just as
it already returns it if there is a PEP 302 loader.
1) #8271: when a byte sequence is invalid, only the start byte and all the
valid continuation bytes are now replaced by U+FFFD, instead of replacing
the number of bytes specified by the start byte.
See http://www.unicode.org/versions/Unicode5.2.0/ch03.pdf (pages 94-95);
2) 5- and 6-bytes-long UTF-8 sequences are now considered invalid (no changes
in behavior);
3) Add code and tests to reject surrogates (U+D800-U+DFFF) as defined in
RFC 3629, but leave it commented out since it's not backward compatible;
4) Change the error messages "unexpected code byte" to "invalid start byte"
and "invalid data" to "invalid continuation byte";
5) Add an extensive set of tests in test_unicode;
6) Fix test_codeccallbacks because it was failing after this change.
Previously, unexpected results occurred when email was passed, for example,
'utf8' as a charset name, since email would accept it but would *not* use
the 'utf-8' codec for it, even though Python itself recognises that as
an alias for utf-8. Now Charset checks with codecs for aliases as well
as its own internal table. Issue 8898 has been opened to change this
further in py3k so that all aliasing is routed through the codecs module.
