Now that we're closer to switching to P3 for good, these helpers have
outlived their usefulness, and mostly add noise.
All remaining dict.iter*() or dict.view*() must be converted to the
normal keys(), values() or items() calls.
Whenever the result is likely to be used for more than the scope of a
loop, or when the dict needs to be modified during iteration, the calls
must be wrapped in a ``list()``, to protect the new P3 semantics.
Those cases are very exceptional.
Also removed some dead code or improved the API to remove unnecessary
conversions.
* remove references to basestring & unicode (use relevant pycompat
helpers)
* remove some str calls (either entirely or replaced by relevant
helper, either text or native)
* use better API to avoid unnecessary conversions
* remove some XML declarations in views
* StringIO removed from stdlib, replace with io
* try to correctly handle BytesIO/StringIO (one is for bytes the other
is for text)
* fix base64: Python 3 removed bytes-encoding and bytes-bytes
codecs (via #encode) so replace all calls to str.encode('base64'),
also b64encode is a bytes->bytes conversion so attempt to properly
handle that
issue #8530
Before 9.0, it was possible to display aggregate values in grouped
Kanban view (like sum, average...). The aggregate was displayed in
the header of the column (see for example in 8.0 in Project >
Tasks).
This feature has been dropped in 9.0 because it didn't work
correctly, but the documentation hasn't been updated accordingly.
The %d %h options in db-filter are case sensitive but the URL are not.
If you happen to use databases with uppercase in the name, using (?i) may be
needed to match the correct database.
