Can anyone think of a situation where a node_load() contained in a function returns partial results when the function is called from a batch script? I have a simple function that I am calling the from a batch API script that processes through a bunch of nodes to fix filepaths in certain migrated content. I've begun experiencing a strange issue while testing it; I've boiled it down to the following test case: <?php function migration_fix_photos($nid) { $node = node_load($nid); dpm($node); drupal_set_message('NID is ' . $nid); } ?> When I call this function with a given NID from a batch script, on some runs, the $node object returned by $node_load is only partially loaded - it has 3 of the 10-12 CCK fields the node should contain, also, $node->title, $node->nid, $node->uid and $node->type are missing from the object, among other portions. The behavior changes between runs of the batch script. I can run a testing run, and only get partially loaded nodes. I can re-run the batch script, and they are fully loaded. Note that this changes per-run of the batch script, not per-call of the function. That is, when the batch script operates on 2000 nodes, the partial node_load() will or will not happen for all 2000 times the above function is run. I could run the batch script again, and get perfectly normal results for all 2000 nodes next time. If I call the above function directly, it shows correct results every time. This only happens when called from a batch script. Note that the $nid argument is always shown as correct (tested with the drupal_set_message() call). Does anyone have any ideas why this is happening? I have tried using Xdebug, but I can't determine how to attach onto the background AJAX requests the browser is making.
