Non-attachment binary fields need to be flushed before reading their
size, since the latter relies on the database's binary size function.
Part-of: odoo/odoo#160708
When invoking create() or write() with a binary field, the cache of the
field was incorrect if bin_size=True was in context. Force context with
bin_size=False when putting a binary value in cache. It is particularly
important to have coherent values in the cache for `web_save`.
Also, because an environment with bin_size=False won't return the same
context cache key as one with bin_size=None, it leads to have a cache
inconstistency when we write with bin_size=False. Change Environment
method cache_key() to return the same cache key when bin_size is absent,
bin_size=None or bin_size=False.
Tests on binary fields have been updated to not rely on flush and
invalidate. We also created specific tests for write() on binary
fields.

BaseModel's sorted() has two problems:
- It breaks the prefetch of self for no reason
- When it is called without an argument, it filters out new records
because the search() used in sorted() doesn't return new records.
Keep the same prefetch as self to fix the first problem.
We partially fix/support the second issue, we just avoid filtering out
new records (but we don't actually sort them)

Since https://github.com/odoo/odoo/pull/1432[FIX] base/models: Prevent incorrect behavior in `_read_group_format_result`
To reproduce the problem, you need to ensure that a read_group returns several groups,
with the first element being a group with no value if you choose to group on a many2many (see test).
Here's an example to reproduce in website_sale:
- Install `website_sale` without demo-data
- Go to `eCommerce/Products`
- Create a new product
- Go to `Sales` tab in the product form view
- Set a new `eCommerce shop/Categories` like `Sales`
- Save
- Return to `eCommerce/Products`
- Remove default filters
- Group by `Website Product Categories`
- There are two group: `None` and Sales`
- Click on None
- Traceback
In this case, the orderby is website_sequence:sum ASC,
and will therefore return as first group None containing `Delivery Product`
and as second group `Sales` containing the newly created product.
What happens is that `read_group` will build `rows_dict` thanks to `_read_group`.
https://github.com/odoo/odoo/blob/cb67b4e1472ae6689e943ade1e27cb43e8d87025/odoo/models.py#L2724
this `rows_dict` will be ordered according to `orderby`and then passed as an argument to the `_read_group_format_result` function
https://github.com/odoo/odoo/blob/cb67b4e1472ae6689e943ade1e27cb43e8d87025/odoo/models.py#L2759
For each row, this function will convert `row[group]` (group in this case is the many2many field)
into a tuple containing (id, displayname) in case the value (`row[group]`)
is found which will be used to build the domain `[(field_name, =, value)]`.
So, for example, replacing
```py
rows_dict = [
groupbyField': odoo.model(1),
groupbyField': odoo.model(4),
]
```
with
```py
rows_dict = [
groupbyField': (1, 'First record'),
groupbyField': (4, 'Fourth record'),
]
```
https://github.com/odoo/odoo/blob/cb67b4e1472ae6689e943ade1e27cb43e8d87025/odoo/models.py#L2460-L2462
If the value is False, we'll use the 'not in' operator instead.
To do this, we need to retrieve the ids of all the other groups to
include in this one all the records that aren't in any group,
either by retrieving the id if it's a model,
or by retrieving the first element of the tuple if it's already been modified,
or by directly retrieving the value of the field if it's not a many2x.
Except that if the first element is directly a group without a value,
it won't be able to retrieve the values of the other groups,
because the condition for checking that it's a `BaseModel` instance contained a typo
https://github.com/odoo/odoo/blob/cb67b4e1472ae6689e943ade1e27cb43e8d87025/odoo/models.py#L2465-L2467closesodoo/odoo#151497

of check_company=True fields.
Suppose two models
class A:
company_id = fields.M2O() # not required
class B:
_check_company_auto = True
company_id = fields.M2O() # not required
a_id = fields.M20(check_company=True)
and the following code:
a = A.create({'company_id': 1})
b = B.create({'a_id': a.id, 'company_id': False})
The creation of B will fail because of the multi-company
checks, which is expected.
Nevertheless, since 0d30cc2bc9, the domain
of the field a_id would be:
(company_id and ['|', ('company_id', '=', False), ('company_id', 'in', [company_id])] or []) + ([])
which means that through the interface, if you create a record b following
the example above (no company_id on b), the evaluated domain would be empty,
allowing to select records of class A, even if they belong to another company.
Of course, this would lead to a multi-company error when trying to save the
record.
This commit makes sure that the right domain is applied on
check_company=True fields, even if the current record has no value
in its `company_id` field.

When we add a new record N to an one2many tree view from an existing
record X form, during the onchange() on the one2many comodel, the cache
of the N.one2many contains only the new record X (the siblings aren't in
it). Because of this, the result of compute methods may be incorrect
and the form won't be updated accordingly. See
https://github.com/odoo/enterprise/pull/52957 for a concrete example.
Technically, this is due to _update_cache() forcing the inverse field
value to the single value of the new record
("not cache.contains(inv_rec, invf)" is True), instead of also
considering the original values (which is properly done by
Field._update()).

Currently, a search with the following domain `[('m2m_field', '=',
False)]` will return only the records for which the m2m field is actually
empty and not take access rights into account. This means that, for a
given user and depending on access rules, `record.m2m_field` can give an
empty recordset while a search using the previous domain won't return
this record.
This behavior is problematic when such a domain is returned by the
read_group. Indeed, when using read_group to group on a m2m field,
records for which this m2m field appears empty for the current user will
be counted in the column 'False'. However, the domain associated to this
column is not always valid, as this m2m field can appear empty for the
current user but still have records in it that the current user does not
have access to. Such records won't be returned by a search performed
using the domain returned by the read_group for the False column.

When using account.root (through account.account().root_id or
account.move.line().account_root_id) in read_group, we can have
inconsistent results because of how account.root is defined.
account_root is a view with the id field computed out of account codes,
but there can be the same account for several companies, so we can have
several same ID for different rows => this is not expected by the ORM
who expects one record by ID => in result, we get for example the values
in the pivot table of journal items be multiplied by the number of
companies if we group by "Account Root".
With this changeset, we add a small optimisation in ORM so if a group by
is ordered by a many2one, if the order of the many2one is "id" we don't
add a left join for ordering.
note: without the change, the added tests failed:
- in account, with 1000 as balance, and 2 as number of root with id=90090
- in test_read_group with a query containing a left join to o2m table
- in test_new_api with a query containing a left join to o2m table

When recursing on non-stored recursive fields, modified() only considers
the records that have some value in cache. But when fields are context-

in the wrong context. Instead, consider cache values in all contexts
for that matter.

The following situation happened with module industry_fsm, when trying
to delete a cancelled sales order corresponding to a task. When doing
so, the server crashes with error "Could not find all values of X to
flush them", which means that a dirty field (pending update) has lost
its value from cache.
The issue is related to recursive computed fields. Before deleting a
record, method unlink() invokes modified(), which determines all the
fields that depend on the record to be deleted, and marks them to
recompute. Those fields should be recomputed after the record is
deleted, and not before. We found out that the recursive call to
modified() made for recursive fields can force the recomputation of the
recursive field itself before the record is deleted, which causes
unlink() to crash.
The fix consists in marking the fields for recomputation at the very end
of method modified(), after all the fields to recompute have been
determined. This ensures that the processing of recursive fields always
uses the current value of the field instead of its recomputed value.

Issue:
======
When you have duplicate groupbys with `lazy=False` you will get an error.
Steps to reproduce the error:
=============================
- Install timesheet
- Go to timesheet / reporting / By Employee
- Add a groupby by month for one employee
- I will show an error.
Origin of the issue:
====================
The timesheet component will the send a request for read_group having
`['date:month', 'date:month']` so we will have duplicated groupby which
will be processed later in `_read_group_format_result` which update the
value of `row[group]` for each group so the first group will have the
original values which is ok but the second one will have the updated
values by the first iteration which will result in error.
Solution:
=========
We need to check that the value is of class BaseModel to update it , it
means that's the first time encountered.

=======

Technical
=========
Because there's no foreign key, when we group by a relational property
we need to check the existence of the ids in the query (and same for
selection and tags, because we might have value of a deleted
option / tag in database).
Task-3032464
Part-of: odoo/odoo#103510
Purpose
=======
Currently, it is possible to use some bad characters in a property name
by writing directly on the parent (not via the child).
It's possible only with RPC call and it wasn't an issue because we
recheck the name anyway before using it in SQL query (but it should be
cleaned).
We also restrict the maximum length (there's nor reason to use
huge property names).
Task-3032464
Part-of: odoo/odoo#103510
When _create() is invoked, it inserts rows into the database, and sets
the cache of the corresponding records to the values that are inserted.
If a field is not passed to _create(), we assume that its database value
will be NULL (or falsy, at least) and put None in cache, in order to
avoid fetching that value. However, this only makes sense for stored
fields.

There are cases where the result of `check_company_domain_parent_of`
is used in in a loop, leading to the parent_of relation being
recomputed once or even multiple times per iteration during SQL
evaluation.
Computing the parent relationship turns out to be fairly expensive in
worst case scenarios (e.g. lots of companies), so while precomputing
doesn't save much for a 1:1 situation (though it does make the job of
the expressions compiler a bit simpler), the ability to compute it
just once instead of say 140 times does make a huge difference in
e.g. some report renderings.
Nota: apparently `_check_company_domain` can be called with a string
because lol, so there's a special case for that.

===
Since 7d2baaa0c7 , we read the field
with `web_read`. We don't load the display name when calling read,
but instead we load them after.
But, since this change, the display names of the relational
properties are not loaded.
To fix that, we always load the display name of the relational
properties because it's a purely frontend field.

It's possible to specify an existing module as the xml id prefix when
importing records from a file. This will result in `ir_module_data`
records being created with `noupdate` set to False. When the module is
upgraded, these records will be deleted.
This can lead to undesired side effects like journal items for
accounts imported this way being deleted.
This change prevents creating new records linked to existing modules
when importing from a file. Instead, the user should either use no
prefix or the name of a non-existent module, like `__import__`.

`_filter_access_rules_python`, everything is consistent.
Also fix `BaseModel._flush_search` to take in account 'any'/'not any'
operators (compulsory in order to flush correctly new domain
from `ir.rule._compute_domain` generated).
Part-of: odoo/odoo#125916
Add test to ensure that `_compute_display_name` is called once with
the correct recordset during `read_group`. Also
fix and small typo in the documentation of `read_group`.

These changes are made as a result of simplifying attrs and 'states' in
views. However, they should have remained in a separate commit. When
applying the script making the xml changes (used later for the migration
script), the script checked the definition of the python fields in order
to convert the information into a python expression. Therefore, this
commit is not applied when the script is applied to xml changes.
During this attribute deletion pre-existing errors were found. Part of
the code was using the boolean values of 'states' and another part of
the code was not. The behavior could therefore be different (in cases
where readonly on the field had the same value as the ballan in
'states').
Following the deletion of 'states' and without the application of the
view migration, the js tests (tower) were no longer functional. Tests
using the Form view suffered the same effect. There are few tests that
had to be adapted, including two tests in business accounting (updated
by the accounting team). A test for column_invisible did not work. Test
checking if the test system triggers an error if we try to write on an
invisible field. It turns out that Form was testing on the value of
invisible but not taking into account if the column was invisible. The
test system fix is applied separately because there were a lot of tests
that were incorrect.

Goal:
* Simplified modifiers to only have one way to define modifiers;
* Remove states attributes on python field;
* Use python expression in view `required`, `readonly`, `invisible`;
* More accurate validation of xml views.
This commit change the syntax to python expression. The next commit
will update/convert all xml views.
Before this commit:
* the `required`, `readonly` and `invisible` attributes can only have
values of `True`, `False`, 1, 0 or a python expression to use the
context;
* the `attrs` attribute define a dict. The key of this dict was
`required`, `readonly` and `invisible` and the values are the domain or
a string representing a domain to be evaluate as python expression.
This python expressions was evaluate by the javascript with view fields
and other contextual values as: context, uid, parent, active_id,
active_ids, active_model, allowed_company_ids, current_company_id.
* the `states` attribute in the view was a comma separated list of the
state. This list was combined with the `invisible` attribute;
* the `invisible` attribute on python field is used as default value;
* the `states` attribute on python field was dictionnary with state as
key and list of tuple. This structure was combined with `readonly` view
attribute.
* After combining, the resulting domains of the different attributes
`required`, `readonly` and `invisible` are evaluated with the values of
the fields. The `invisible` attributes is splitted into two use:
`invisible` and `column_invisible`.
After this commit:
* The attributes `required`, `readonly`, `invisible` and
`column_invisible` define python expression. This python expressions
are evaluate by the javascript with view fields and other contextual
values as: context, uid, parent, active_id, active_ids, active_model,
allowed_company_ids, current_company_id.
The domains can contains contextual value and will be evaluate by the
javascript.
```xml
<field name="field_a" readonly="not context.get('show_a')" attrs="{'readonly': [('field_b', '!=', False), ('field_c', '=', parent.c)]}"/>
<field name="field_b" states="draft"/>
```
will be replaced by
```xml
<field name="field_a" readonly="not context.get('show_a') or field_b and field_c == parent.c"/>
<field name="field_b" invisible="state != 'draft'"/>
```
Some inherited views will be modified differently in order to maintain
the previous behavior:
```xml
<field name="field_a" readonly="not context.get('show_a')" attrs="{'invisible': [('field_b', '!=', False)]}">
```
```xml
<field name="field_a" position="attributes">
<attribute name="attrs">{'readonly': [('field_c', '=', False)], 'invisible': [('field_d', '!=', '3')]}<attribute>
</field>
```
will be replaced by
```xml
<field name="field_a" readonly="not context.get('show_a')" invisible="field_b">
```
```xml
<field name="field_a" position="attributes">
<attribute name="readonly" add="(not field_c)" separator=" or "/>
<attribute name="invisible">field_d != 3<attribute>
</field>
```
Validation:
A stricter control is made on the level of the attributes (modifiers)
and the fields necessary for these. The use of the previous attributes
'attr' and 'states' triggers an error (these no longer exist after the
application of the migration script)
