For companies not working with variants,
it is important to be able to search in the
Products menu (product.template) using
product codes.
It is useful as well to see the codes
in the default kanban view too, even if
it is only the code of the first variant.
Takes care of resetting it from older versions
e.g. rev d97e7a6a4e
and c0076916f3, as
the old `variants` field that was used does not
exist anymore, crashing at opening.
Unify and refactor exception handling in framework and addons.
The generic `except_osv` is now deprecated, and replaced by more specialized exception subtypes:
- `UserError` (renamed from Warning, as it conflicts with the built-in `Warning`) raised when a non-technical error occurs during a business operation. It could be a missing information in the data provided by the user, or a misconfiguration.
- `AccessError`: raised when any operation is denied because the user conducting it does not have the required access rights.
- `AccessDenied`: raised when an operation that requires authenticated access is attempted via an unauthenticated request.
- `MissingError`: raised when an operation is attempted on a record that does not exist.
- `ValidationError`: raised when an operation violates a SQL or Python constraint.
- All other exceptions are internal errors due to a system problem or bug, and raised untouched to the client-side, which should display a traceback.
All exceptions take a single message argument.
The `test_exceptions` module has been updated to showcase both new and old (deprecated) exceptions.
A great many old `except_osv` had a useless title with "Error!" or "Warning", those have been removed, as this is handled by the client-side widget that displays the messages.
This commit introduces a more consistent policy for logging errors and warnings:
- All messages that do not require administrator attention should be logged at INFO level or lower. This includes all errors that are notified to the user in a friendly manner, even for access right problems or validation errors during business operations.
- All messages that indicate a likely misconfiguration or malicious use by the users should be logged at WARNING level, as they typically require administrator attention.
- All other unhandled internal errors cannot typically be handled by the user and should be logged at ERROR or higher level, as they require immediate administrator attention.
When adding an extra price for a variant (through the button variant prices in the product template form) with a digits precision greater than 2 (4 for instance), the computed public price did not keep the digits precision of the extra price
The default UoM can only be changed when there are no stock moves (or only cancelled ones), but to any category.
The purchase UoM can be changed whenever you want, but has to be in the same category as the default UoM.

Granting read-only access to Sales/Accounting Users is useless
as all employees already have it - removed. On the other hand
Sales Managers need write access to it in order to create
products, and they need it even when `sale` is not installed,
e.g. with `account` only.
Moved this access right to `product` module. The Sales
Manager group is defined in `base`, so that works.
Add restriction on product_id field to prevent the suppression of the product
if already present in an invoice.
This is to avoid the suppression of a used product variant when modifying
the list of attributes.#
Due to the constrain, the variant will be disabled instead of deleted.
Fixes#4129
Add warning message on the product form to warn users about the potential impact
of modifying variants.
Pricelist computations need to consider 2 different Units
of Measure:
- The default product UoM (product.uom_id), used as reference
for the various quantities and amounts specified in each
pricelist rules.
- The `context UoM` is the UoM in which the result is requested,
that is the list price UoM.
For example the 'price_min_margin' amount is meant for the unit
price of 1 x default UoM. When the context UoM is not the default
product UoM, it can be any UoM of the same UoM Category, and the
various quantities and amounts specified on the rule need to
be adapted accordingly:
- min_quantity (expressed in terms of the default UoM)
- price_surcharge (specified for 1 x default UoM)
- price_min_margin (specified for 1 x default UoM)
- price_max_margin (specified for 1 x default UoM)
The UoM corrections were not done consistently and resulted in
wrong prices when computing the price using a non-default UoM.
The cases were a conversion was needed or not were not properly
identified within the _price_rule_get_multi().
After this commit, the various code branches in _price_rule_get_multi
always ensures that:
- price requested for: `qty` of `qty_uom_id`
- `qty_in_product_uom` is the requested `qty` converted to default UoM
- current (intermediary) price: `price` for `price_uom_id`
Therefore `price` and `price_uom_id` are always in sync, and `price_uom_id`
can always be compared with `qty_uom_id' in order to know whether
a conversion is still needed.
This patch also corrects and extends the regression tests
introduced at revision 79ebe10.
Reintroduction of field mes_type on product.template. This field was not
used in the code anymore, but we keep it for future use.
This field allows the user to express that there is no fixed conversion
rate between uom and uos.

Remove the intermediate rounding inside _compute_qty(), as it
is not necessary after rev. fa2f7b86 and has undesired side-effects.
An extra float_round() operation inside _compute_qty()
had been added at rev. 311c77bb to avoid a float representation
error in UoM factors that could bias the ceiling() operation
done as the last conversion step.
Example 1:
Dozen has a factor of 1/12, which was previously stored in the
database with a decimal accuracy of 12 significant decimal digits.
This meant the factor was exactly stored as 0.08333333333333.
When reading this back into a Python float, the precision was not
sufficient, and the UoM conversion of 1 Dozen to Units gave a
result of 12.00000000000047961...
After the final ceiling() operation to Unit's rounding, the
converted value ended up as 13.
This problem was initially solved using an extra rounding.
However at revision fa2f7b86 the decimal precision used to store
UoM factors was increased to preserve all significant digits.
This added the extra precision necessary to read the Dozen factor
back into an accurate float value of 1/12, and the conversion of
1 Dozen now gives 12.0 Units, even without the intermediate
rounding operation. (Works for other factor values too)
At the same time that extra rounding operation has undesired
side-effects, as it requires a fixed precision derived from
the rounding precisions of the UoMs. But there is no given precision
that would work in all cases for this intermediate value. It is
always possible to find a valid combination of UoM roundings
that breaks that intermediate step, e.g. by forcing integer
roundings.
Example 2:
Let Grams have a rounding precision set to 1 because no smaller
quantities are allowed, and Kilograms a rounding of 0.001 to allow
representing 1 Gram. (gram factor = 1000 and kilogram rounding = .001
by default)
If we try to convert 1234 Grams into Kilograms, the extra rounding
introduced in 311c77bb will cause a rounding of 1234.0/1000.0 at
the precision of Grams (1), which gives 1.0 as a result.
The net result of this conversion gives 1234.0 Gram = 1.0 Kilogram,
while the correct result (1.234 Kilogram) is perfectly compatible
with the UoM settings.
Similar errors could be triggered with various rounding settings, as
long as the intermediate rounding needs a finite precision.
Two extra tests have been added to cover Example 1 and Example 2.

When adding informational attribute, with only one possible value, it used to be skipped.
Instead keep it and add it on every variant.
To avoid dropping and recreating product (and lose eventual customisations), the attributes with only one possible value are set on every product.
This makes sure that in following test, these are not considered in variants_inactive variable.
Fixes#3204
