* provided `inner` data may or may not have been encoded
* `element.text` is either ascii-compatible `str` or `unicode` when
non-ascii-compatible, which could force the decoding of utf8-encoded content
during g_inner's join
At rev 84e9a67cdf a check to avoid the creation of ir.model.relation for custom modules was added. The condition is not correct as based on the string instead of the field name. We do not have access to column name at this level but the the m2m relation table do start with x_ for custom fields (see __init__ method).
This should fix an issue discovered by tde when reading all fields on a record
on which you don't have access right:
- _read_from_database() fetches result and store it in cache
- read() retrieves values from cache, starting with field 'create_date'...
- ... which is not in cache, so prefetch that field, read it, which goes into
an infinite loop
The problem is that _read_from_database() finds out that you don't have access
on the record, and stores a FailedValue in cache on all fields... except magic
fields. Fix the problem by storing the FailedValue on all fields but 'id'.
orm: do not try to create ir.model.relation for custom m2m as self._module is either empty (for custom models), either the one of the last inheriting module (which is wrong). The field should be removed manually and should not be impacted by the uninstallation of modules. The removal of the relation table can be done when removing manually the custom field (see rev 6af3193).
ir.model: when removing a model, drop the table with the CASCADE instruction. This will remove left constraints from remaining m2m tables.
This means that dropping a table (either manually removing a custom model or uninstalling a module) will not drop the relation table for a custom m2m field. This is not ideal but better than the previous behaviour (which was to fail the DROP TABLE instruction and keep the table with a few columns and unconsistent data).
lxml (used by the html sanitizer) really does not like documents as unicode
strings with an encoding declaration (which doesn't make sense indeed), yet
docutils with output_encoding=unicode generates one (a stupid one too, says
"encoding=unicode").
Disable the xml declaration altogether when compiling rST module declarations
to HTML.
When droping a column, remove also the relation table in case of custom m2m field.
The relation table needs to be dropped otherwise an unremovable constraint to the targetted table is kept (and anyway is not needed anymore).
- sessions are now shared between series.
- use site data dir instead of user data dir if user has no home dir.
- in http and module handling, `data-dir` was used before being
initialized, using the default value instead of user input

* Either further operations don't really care (e.g. ``str.join`` takes any
iterable)
* Or they do their own seq (``browse`` calls ``tuple()`` on iterable params)
Fixes#966
* As a preallocation optimization, ``list()`` calls ``__len__`` on its
parameter if it's available
* Before Python 2.7.4, WeakSet has a bug[0] where ``len()`` is unsafe: it is
done by iteration and weakrefs may be removed from the underlying set during
the iteration
As a result, the safety feature of listifying a WeakSet to ensure we have
strong refs on all items during iteration may blow up.
Wrapping the weakset in a ``iter()`` makes ``__len__()`` invisible and ensures
we're within the IterationGuard[1].
Which now that I think about it means we *should* be able to safely iterate
weaksets in the first place and may not have needed to listify them...

Likely caused by a type incoherence e.g. providing an id as string when the
table uses integer ids. Postgres performs an implicit conversion from string
to integer[0], this wasn't much of an issue in the old API, whatever cache was
there would simply not be used, but because the new API's cache is part of its
behavior it has a semantic impact and can lead to infinite recursion.
