Description
Using public API, if we perform a legacy call the output buffer gets cleared for some reason.
This doesn't seems the correct behavior.
Steps to reproduce:
Create a bundle, and add a command to it, containing the following code:
// Generate output buffer
ob_start();
echo "test\n";
$levelBefore = ob_get_level();
// This legacy call will clean the ob and discard our output of 'test'
$closure = $this->getContainer()->get('ezpublish_legacy.kernel');
$legacyKernel = $closure();
$legacyKernel->runCallback(
function () {
},
false,
false
);
// Dump differences
$levelAfter = ob_get_level();
$content = ob_get_clean();
printf("ob_get_level() before legacy call: %d\n", $levelBefore);
printf("ob_get_level() after legacy call: %d\n", $levelAfter);
printf("Content: %s\n", $content);
The content of $levelAfter should be the same as $levelBefore, but it isn't, because the output buffer has been flushed.
The same can be tested with ob_get_contents():
// Generate output buffer
ob_start();
echo "test\n";
$bufferBefore = ob_get_contents();
// This legacy call will clean the ob and discard our output of 'test'
$closure = $this->getContainer()->get('ezpublish_legacy.kernel');
$legacyKernel = $closure();
$legacyKernel->runCallback(
function () {
},
false,
false
);
// Dump differences
$bufferAfter = ob_get_contents();
$content = ob_get_clean();
var_dump($bufferBefore);
var_dump($bufferAfter);
printf("Content: %s\n", $content);
Which will output:
string(5) "test " bool(false) Content:
bool(false) will be returned when dumping $bufferAfter because the output buffer has been flushed after the legacy call.
