In Python 3, all of these were "consolidated" under urllib(.request,
.parse, .errors) which is inconvenient.
Since we already have hard dependencies on requests and
werkzeug(.urls, which is a backport of Python 3's unicode-aware
urllib.parse) migrate *everything* to that.
A sticking point is urllib2.URLError, those were (mostly) replaced by
the slightly more general IOError which URLError extends.
In Python 3:
* various builtins and dict methods were changed to return
view/iterable objects rather than lists
* and the separate Python 2 view/iterable builtins and methods were
removed altogether
This is problematic when using these items as list (which the happens
repeatedly in Odoo), but more viciously when iterating *multiple times*
over them (which also happens, which I've messed up multiple times while
writing this, and which is a pain to debug even when you've just created
the issue).
Convert all code using these to semantics-matching cross-version
helper functions to get the LCD behaviour between P2 and P3, and
forbid the builtins via lint.
issue #8530
Links containing HTML escaped characters,
such as the ampersand
`&` escaped `&`
were not shortened correctly:
Their redirecting URL contained the escaped value
(e.g. `&`) instead of the actual character,
leading to the wrong redirected URL.
e.g. creating a mass-mailing with a link
contains as query string
?test1=1&test2=2 were shortened
with as redirect link
?test1=1&test2=2

When tracking a page with special characters
in the title (e.g. `Ä`), the title
of the page in the tracked links was
badly encoded, because the
encoding was not handled correctly
when parsing the given website page.
