Remove weird special case: when the first field of the first line of a one2many
is empty, replace this first field by the comma-separated names of the lines,
and discard the other lines.
Otherwise if a record rule is defined on a x2many field on the model, the creation will fail because
ir.translation creation check access rules on the model and in this case, the x2many relation are
not set yet.
The behavior is no longer implemented by the web client. Implement it
server-side as part of the onchange mechanism, simply by defining onchange
methods for the fields that have the flag.
In case of foreign language, using unicode characters, the error message may be
badly formated.
e.g.
Unknown error during import: <class 'odoo.exceptions.AccessError'>: เฉพาะผู้ดูแลร..

When deciding to prefetch records (getting records from the cache with
no value for the field being fetched), if the field was computed
`determine_value` would just get all records, not limited by the normal
prefetch limit; for large recordsets this would generate gigantic
prefetch lists for records we may not need at all.
Fix by applying the `PREFETCH_MAX` limit to records from the cache as is
done in `_prefetch_field`.
Complementarily, when traversing related fields the prefetch
environment would be lost and every record would get an empty prefetch
environment, so the values would ultimately be read one by one.
Example: select (search) 1000 product.product records, access a
related field (e.g. categ_id) in a loop, on the first iteration the
system would first read 1000 templates, then it would read each
categ_id individually, resulting in >1000 SQL queries rather than the
~2 we would expect.
Fixes#18511
When a model contains a field translatable which has a unique
constrain, it is impossible to copy a record. Indeed, the unicity
constrain is always triggered, even if the model takes in charge the
overriding of the copy method to avoid duplication.
Introduced with commit ce7f31b0b0, with the goal to target only
XML/HTML translations. We apply this behavior in case of a callable
translate property, to target only the desired problematic use case.

Issue: when using `copy` in a given lang, the value of XML/HTML fields is
copied in its translated form, making existing translations useless. Fix the
value of such fields by storing their original value instead.
The attribute `group_expand` allows to reorder and add empty groups to the
result of `read_group`. Enable this feature for other fields than many2one
fields.
Problem: the update of custom models/fields is not fully transactional, and may
potentially lead to an inconsistent database. An other problem is creating two
custom fields by writing on a model: if the second one fails, the first one has
been committed without notice. Retrying the request will give an unexpected
error (duplicate field name).
Solution: never commit in the middle of a request. If the changes have an
impact on the registry, then mark it as invalid (with a new flag), and signal
registry invalidation after everything has been committed. If the request
fails, reset the registry. Both registry and cache invalidation are handled
the same way.
