In python3, items() and keys() returns iterators.
Modifying a dictionnary while iterating on it may trigger an error:
dictionary changed size during iteration
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.
Rev. c5bd509274 attempted to improve the
pad sync mechanism when merging records (tasks), but failed to consider
the case where the pad_url field is not set yet.
This happens at create(), due to the chicken-and-egg problem with the
pad URL depending on the record ID, and therefore set *after* creation.
Ignoring the sync when the URL is not yet set should be enough, as the
URL generation method also takes care of that first sync.
If the pad content field is modified in Odoo, the content of the pad should be modified too.
Example: When merging tasks, the tasks descriptions are concatenated into the target record. But the taregt pad is not modified if it already exists.
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
=======
Purpose
=======
The company form should be heavily simplified. It's complex to have some settings on the company form, and others on the Settings menu of the related app. It would be much easier to have all settings in Settings menu (res.config) and nothing on the company, even if some of the Settings are multi company. (Stored on the company but set from the Settings menu).
