Web client use fields_get (which one call get_description) to know if
a group operator exists. But until now, group_operator are never returned.
Without it, the web client cannot display the sub-total except for sum
(the fallback in the web client).

Todo: do the same on Class Monetary in next branch
Our usage of domain on fields One2many seems to trigger an obscure behaviour on
onchange.
With the following (simplified) config:
Message(models.Model):
_name = 'test_new_api.message'
important = fields.Boolean('Important')
Discussion(models.Model):
_name = 'test_new_api.discussion'
name = fields.Char('Name')
important_emails = fields.One2Many('test_new_api.emailmessage', 'discussion',
domain=[('important', '=', True)])
Email(models.Model):
_name = 'test_new_api.emailmessage'
_inherits = {'test_new_api.message': 'message'}
discussion = fields.Many2one('test_new_api.discussion', 'Discussion')
message = fields.Many2one('test_new_api.message', 'Message')
Steps:
- We change 'name' on discussion, triggers an `onchange()` call
- we ends up filling cache on virtual record (on secondary fields, we calling
record.mapped('important_emails.important'))
- we get a cache miss ('important' field not provided, only 'important_emails' ids,
i.e with no change on existing records)
- we fill the cache, this mark 'important' field as modified
- because of commit 5676d81 and because 'important' is that case is a related (i.e
computed) field we triggers cache recomputation
- as there is no way to recompute 'important_emails' for virtual record (no real
ID) we ends up with empty 'important_emails' generating removal of existing records.
=> Finally changing any value for 'test_new_api.discussion' that trigger an onchange
will always reset 'important_emails' to empty

Invalidate the cache of a x2many field when any of the fields appearing in its
domain is modified. Use the invalidation triggers mechanism for that purpose.
When traversing relational fields as superuser, you end up with a recordset for
which only a subset is accessible to the current user. An earlier fix to this
issue completely dropped the `related_sudo` feature; change its implementation
to keep the feature.
The recursion was based on an incorrect assumption: the cache of the target
environment is initially empty. If another computation left some value there,
the copying is incomplete, and that causes bugs in onchanges.
Borrowing a cursor each time you access `field.digits` may be costly, because
of the connection reset. Moreover, in most cases, the cursor is not used at
all, since the decimal precision are kept in cache.
For the installation of module `product` with its demo data, the number of
cursor allocations was reduced from ~1500 to about 50!
Traversing new records in a different cache requires that all new records on
the path are copied across caches. Make the copy across caches recursive when
the first record on the path is a new record.
xmlrpc 1.0 does not support None/null, so commit f3e4d0a will break xmlrpc api.
Therefore, we export an empty string if the field is empty, instead of False or
None. For integers and floats, zero is exported.

If we export False or an empty string, the Excel export will consider the field
similarly to a boolean, and en empty value will be converted into "=False()" in
Excel. To prevent this, we return "None" in the following cases:
- String
- Date
- Datetime
- Selection
- Reference
- Many2one
- RelationalMulti

Pretty much completely rewritten theme with custom HTML translator and a
few parts of the old theme extracted to their own extensions.
Banner images thought not to be that huge after all, and not worth the
hassle of them living in a different repository.

Thamks to parent commit, `request.env` doesn't raise `AttributeError`
anymore for requests without session bound to a database.
This exception was bubbling up to `digits` property (and `__getattr__`)

This revision introduces an issue more serious than the ones
it fixes. This is no longer possible to receive an email
aimed a sale.order thread with catchall.
To reproduce the issue:
- Create a new sale order
- Send a message in the thread to the customer
- Reply to the mail received in the customer mailbox
- Traceback, AttributeError: digits
opw-640370
The computation of property `digits` was creating a new cursor to call the
function that determines digits. This technique is fragile because the current
cursor may have pending updates that the new cursor will not see.
The issue was discovered by Cécile Tonglet (cto). She observed an infinite
loop during a database migration, and a traceback inside the loop showed the
presence of the `digits` property. This change fixes the infinite loop issue.
context_timestamp should always return a timezone aware timestamp, even when
no timezone is set on the user.
7f88681 fixed the bug in old api fields (openerp/osv/fields.py) but it was not
applied to new api fields (openerp/fields.py). opw 616612
In `__getattr__`, remove the test on accessing `_attrs`. This situation should
never happen, since the attribute `_attrs` is set in method `__init__()`.
Introduce slots on all field classes for common attributes; slots take much
less memory than a `__dict__`. The other attributes are stored in a dictionary
`_attrs`; all fields with an empty value for `_attrs` (common case) share the
same empty dictionary. This saves quite some memory (around 4.5Mb per
registry), given the number of field instances created for a registry.
Another mechanism is used for the default values of attributes, since slots
cannot be assigned on classes.
The optimization consists in using tuples for attributes `inverse_fields`,
`computed_fields` and `_triggers`, and to let them share their value when it is
empty, which is common. This saves around 1.8Mb per registry.
This saves about 400Kb per registry by not allocating those lists, which are in
most cases empty. The removal of the attribute will also simplify a bit the
management of free attributes.
The computed value of parameter digits is no longer stored into fields and
columns; instead the value is recomputed everytime it is needed. Note that
performance is not an issue, since the method `get_precision` of model
'decimal.precision' is cached by the orm. This simplifies the management of
digits on fields and saves about 300Kb per registry.
For public-facing HTML content provided by the user,
`<style>` tags and `style` attributes should be stripped
automatically, as they can easily be abused to deface
pages for abusive users and spammers.
<style> tags were already stripped, the optional `strip_style`
for fields.html enables the automatic stripping of style
attributes.
This is opt-in because custom style attributes are still
desirable in trusted HTML fields.
Improve the performance of `name_get()` on many2one field values by making sure
that the records on which `name_get` is invoked are prefetched in cache. This
is not automatic, because `name_get` is invoked on records in another
environment (sudo mode): the prefetching in the original environment should be
reproduced in the other environment.
The implementation was based on the ill-defined method `same_parameters()` that
compares arguments based on a heuristic. Instead, we now create a new column
and check whether it is equivalent to `self` by comparing the arguments
returned by `to_field_args()`. If that is the case, `self` is reused instead
of the new column.
The code refactoring also fixes the column reuse which was broken by the
introduction of the parameter `compute` in commit 9333c62. Indeed, with that
parameter, `same_parameters()` always returned False, since old-api columns do
not have that parameter by default. The parameter has been renamed to
`_computed_field`, and is no longer passed for creating columns.
When overriding a field defined as a function field, the field must either
create a corresponding column that is not a fields.function (if stored), or
have no corresponding column (if not stored).
Idea: look up for the model's fields in method `_setup_base()` instead of
method `__init__()`. This does not make a significant difference when
installing or upgrading modules, but when simply loading a registry, the
(expensive) field lookup is done once per model instead of once per class.
The mechanism to determine the table and column names of new-api many2many
fields only worked for many2many fields created from old-api many2many columns!
This fixes#4851.
This reverts commit 8cd2cc8910.
It turned out that forcing recomputing fields as user admin breaks some
existing behavior. Instead, we make the recomputation as user admin explicit
by adding compute_sudo=True in the field's definition.
This log line is only useful when debugging registry
loading, a limited use case now that Odoo 8 is stable.
It makes the debug log more difficult to read and causes
a small performance penalty when debug[_rpc] is on.
(+0.2s i.e. 10% extra time for loading a registry with 47
modules on a core i5-4200U machine)
The model setup sometimes misses entries in _inherit_fields and _all_columns.
This is because those dictionaries are computed from parent models which are
not guaranteed to be completely set up: sometimes a parent field is only
partially set up, and columns are missing (they are generated from fields after
their setup).
To avoid this bug, the setup has been split in three phases:
(1) determine all inherited and custom fields on models;
(2) setup fields, except for recomputation triggers, and generate columns;
(3) add recomputation triggers and complete the setup of the model.
Making these three phases explicit brings good invariants:
- when setting up a field, all models know all their fields;
- when adding recomputation triggers, you know that fields have been set up.
This is necessary for supporting old-api sparse and serialized fields. Without
this, old-api serialized fields are broken because they cannot be converted to
new-api fields.
This closes#4571
For models using a datetime field as name (hr.attendance for instance), the user timezone wasn't applied in the display name.
Therefore, in the breadcrumb, the datetime was different than in the form if the user had another timezone than UTC.
This rev. is related to 27d8cb843b, but is for the 8.0 api
We are aware we introduce a tiny change of API (method signature change), which we normally prohibit, but considering the really low level of the method, the fact it is probably not ovveriden by any other modules and the fact there is no cleaner way to correct this, we are making an exception.
