Closed, ResolvedPublic
Actions

Description

  1. PHP 8.2.12, Phorge at d4b110af260caab56936aab543041b0904e4d02a
  2. Go to http://phorge.localhost/differential/diff/create/
  3. Paste random (but valid) diff content
  4. Click Create Diff button
  5. Go to http://phorge.localhost/feed/transactions/query/advanced/ and set Object Types to Differential Diff and click Search button
  6. See two entries listed instead of one; one entry has no Transaction column entry, thus in consequence also get ERROR 8192: strncmp(): Passing null to parameter #1 ($string1) of type string is deprecated at [/var/www/html/phorge/phorge/src/applications/policy/query/PhabricatorPolicyQuery.php:314]

My initial choice of words was wrong: It's not "duplicated". SELECT * FROM differential_difftransaction WHERE dateCreated > 1705224003; shows two transactions differing in id, phid and transactionType (differential:diff:create versus core:view-policy).

The "empty" entry is the transaction to set the initial view policy.
getTitle() in https://we.phorge.it/source/phorge/browse/master/src/applications/differential/storage/DifferentialDiffTransaction.php;4862eada5cd05236b81487b261668f2a2d72fad7$36-41 does not cover our case PhabricatorTransactions::TYPE_VIEW_POLICY so it return parent::getTitle() instead.
The parent does cover our case PhabricatorTransactions::TYPE_VIEW_POLICY in https://we.phorge.it/source/phorge/browse/master/src/applications/transactions/storage/PhabricatorApplicationTransaction.php;4862eada5cd05236b81487b261668f2a2d72fad7$943-970 but for some reason $this->getIsCreateTransaction() is not true so we wrongly end up in the else section of the code.
Manually negating the check by adding the ! to if (!$this->getIsCreateTransaction()) made the empty line in the Feed go away and correctly display '%s created this object with visibility "%s". as expected.

So getIsCreateTransaction() is wrong here. In https://we.phorge.it/source/phorge/browse/master/src/applications/transactions/storage/PhabricatorApplicationTransaction.php;4862eada5cd05236b81487b261668f2a2d72fad7$153-155 it simply calls $this->getMetadataValue('core.create', false); and returns false when the key does not exist in the metadata of the transaction.
So I assumed that we miss adding core.create to the metadata for the transaction type core:view-policy when creating a new Diff.
setIsCreateTransaction() in https://we.phorge.it/source/phorge/browse/master/src/applications/transactions/storage/PhabricatorApplicationTransaction.php;4862eada5cd05236b81487b261668f2a2d72fad7$149-151 does so, and it is called in applyTransactions() in https://we.phorge.it/source/phorge/browse/master/src/applications/transactions/editor/PhabricatorApplicationTransactionEditor.php;4862eada5cd05236b81487b261668f2a2d72fad7$1315 .

Looking higher in https://we.phorge.it/source/phorge/browse/master/src/applications/transactions/editor/PhabricatorApplicationTransactionEditor.php;4862eada5cd05236b81487b261668f2a2d72fad7$1175-1179 , $this->isNewObject is correctly set to true.
However, later that is not used in https://we.phorge.it/source/phorge/browse/master/src/applications/transactions/editor/PhabricatorApplicationTransactionEditor.php;4862eada5cd05236b81487b261668f2a2d72fad7$1303-1317 which defines the criteria when to set $xaction->setIsCreateTransaction(true):
It checks if $xaction->getTransactionType() == PhabricatorTransactions::TYPE_CREATE.
But in our case, the transaction type is DifferentialDiffTransaction::TYPE_DIFF_CREATE instead.
Thus it is incorrectly not considered a new object and stuff fails.

The patch in D25517 does not retroactively fix this but avoids this problem for future diffs created.
