* NEW: Add extrafields support to Link class
Link now declares isextrafieldmanaged and wires fetch_optionals()/
insertExtraFields()/deleteExtraFields() into fetch(), fetchAll(),
create(), update() and delete(), matching the llx_links_extrafields
table added previously.
* FIX: Several bugs in Link class review
- create(): wrong duplicate-record error message (copy-pasted from
Societe, referenced undefined $this->name) replaced by the generic
ErrorDuplicateField, consistent with update().
- create()/update(): missing "NoURL" translation key replaced by the
standard ErrorFieldRequired pattern.
- fetch(): guard against running an unfiltered query (no rowid, no
hashforshare) that could silently return an arbitrary link; a caller
in actions_linkedfiles.inc.php could hit this when 'linkid' was
missing from the request.
- actions_linkedfiles.inc.php: check fetch() result with `> 0` instead
of a truthy test, since -1 (error) is truthy in PHP.
- delete(): add User type hint (consistent with create()/update()) and
a $notrigger parameter to optionally skip the LINK_DELETE trigger.
- update(): fix copy-pasted docblock ("third party" -> "link").
* NEW: Add PHPUnit test for Link class
Covers create/fetch/update/fetchAll/count/delete, plus regression
tests for the two bugs fixed in the previous commit: create() rejects
an empty url, and fetch() rejects a call with neither rowid nor
hashforshare instead of returning an arbitrary record.
* FIX Phan false positive on $object in actions_linkedfiles.inc.php
Phan's ambient type inference for the loosely-typed global $object in
this shared include file was picking up CommonSocialNetworks (an
unrelated trait, not even a class), reported as undeclared
->id/->entity/->addThumbs()/->delThumbs() in a real CI Phan run on
this branch, once this file was analyzed on its own via the
changed-files file-list (this file has no prior baseline entry, so it
was apparently never previously exercised in isolation like this).
Force $object's type explicitly to CommonObject via the same
@phan-var-force string-literal idiom this file already uses for
$upload_dir/$upload_dirold/$confirm/$forceFullTextIndexation -
CommonObject genuinely declares addThumbs()/delThumbs(), which
resolves those two errors outright. $id/$entity remain reported as
PhanUndeclaredProperty (CommonObject itself does not declare them,
only its concrete subclasses do at runtime) - baseline-suppress that
for this file the same way it is already suppressed for the sibling
shared-include files actions_addupdatedelete.inc.php,
actions_massactions.inc.php and actions_sendmails.inc.php, which have
the exact same $object typing situation.
