This provides a mechanism for adjusting the behaviour of these
relations when building more complex data models.
For example the following example has a status field incorporates a
Status field into the relationship:
```php
function MyRelation() {
$rel = $this->getManyManyComponents(‘MyRelation’);
$rel = $rel->filter(‘Status’, ‘Active’);
$rel->addCallbacks()->add(function ($relation, $item, $extra) {
$item->Status = ‘Active’;
$item->write();
});
}
```
Introduces a new library dependency: http://github.com/sminnee/callbacklist
When many-many-through relations are queried, a joinRecord is set on
each DataObject in the list to provide the extra fields defined on
the connector object. This didn’t previously happen when the record
was first add()ed to a list. This fixes that bug.
The query might still work depending on where these chars are placed,
but it seems weird to only remove *some* of the valid chars here.
See https://dev.mysql.com/doc/refman/5.6/en/fulltext-boolean.html
Note that the query runs both the actual boolean query with chars,
and then a separate relevance search without them.
MyISAM used to be the only one to support it, now InnoDB has caught up.
Unless an engine is set specifically in create_table_options,
this will auto-convert existing MyISAM tables to InnoDb.
Fixes#9242
ContextSummary() was cutting the HTML which was added by nl2br because
it expected plain text elements as it's stripping and replacing text.
Instead this fix changes the behaviour to apply the nl2br after the text
changes have been made. That way we can't cut anything in the middle of
a HTML tag, but new lines, or paragraphs are replaced by BRs after,
should they exist.
- Added tests to ensure text is not cut in the middle of a sentence.
- Added test to ensure that <br>'s are added in the correct place should
the summary span between new lines.
API: Query::seek() and Query::rewind() no longer return a value.
Although breaking an API inside a patch release may seem odd, this in
fact is correcting a long-standing bug in our implementation of
Iterator::rewind(), so I think it’s appropriate.
