Description
Original report URL: https://github.com/couchbase/php-couchbase/pull/27
I was getting segfaults in my Symfony application when using ViewOptions->keys() and Bucket->viewQuery(), but at first only when from inside a controller action.
When I tried narrowing it down and tried only the view query in a single procedural script, it did not segfault. But when running this script with USE_ZEND_ALLOC=0 did give a weird result.
The php script looks like this:
$cOpt = new \Couchbase\ClusterOptions();
|
$cOpt->credentials('admin', '****');
|
$cluster = new \Couchbase\Cluster('couchbase://couchbase', $cOpt);
|
$bucket = $cluster->bucket('data');
|
|
|
$opt = new \Couchbase\ViewOptions();
|
$opt->keys([1, 2, 3]);
|
|
|
$result = $bucket->viewQuery('item_collection_dag_node', 'item_collection_id', $opt);
|
When run with USE_ZEND_ALLOC=0, this results in:
$ USE_ZEND_ALLOC=0 php tests/e.php
|

|

When run with `valgrind` it reports:
$ USE_ZEND_ALLOC=0 valgrind php test/e.php

Commenting out the $opt->keys([1, 2, 3]); line removed the errors.
This PR fixes this and according to `valgrind` does not seem to leak memory.
