The mappings model._all_columns takes quite some memory (around 2MB per
registry) because of the numerous dictionaries (one per model) and inefficient
memory storage of column_info. Since it is deprecated and almost no longer
used, it can be computed on demand.
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.
This was due to secondary fields loaded from database in 'onchange' mode. In
that mode, the secondary fields were marked 'dirty', and therefore returned by
the method `onchange`. The fix consists in loading those secondary fields in
cache before processing the onchanges.
This incidentally fixes a test on method `onchange`: in a one2many field, some
dirty fields were unexpectedly returned in the result. This was due to those
fields being loaded while processing onchanges.
Compute methods could give results that should not be considered as default
values. For instance, a related field usually defaults to a null value, which
is then set to the field with its inverse method by create(). This may violate
a non-null constraint if the original field is required. Therefore, compute
methods are no longer used to determine default values.
A squashed merge is required as the conversion of the apiculture branch from
bzr to git was not correctly done. The git history contains irrelevant blobs
and commits. This branch brings a lot of changes and fixes, too many to list
exhaustively.
- New orm api, objects are now used instead of ids
- Environements to encapsulates cr uid context while maintaining backward compatibility
- Field compute attribute is a new object oriented way to define function fields
- Shared browse record cache
- New onchange protocol
- Optional copy flag on fields
- Documentation update
- Dead code cleanup
- Lots of fixes
