| Summary | 0001541: switch/case case is not covered when using php-fpm php 7.0 | ||||
| Description | When executing switch/case within a function, no case line of executed cases is marked as covered, except the following: * The first line is marked as covered as expected * The "default" case is marked as covered as expected The lines are marked as covered as expected when the same file is executed via CLI using same php/xdebug version. {code}
<?php
function a($option) {
switch ($option) {
case 'first':
$option .= '_covered';
break;
case 'second':
$option .= '_covered';
break;
case 'third':
$option .= '_covered';
break;
default:
$option .= '_covered';
break;
}
return $option;
}
xdebug_start_code_coverage(XDEBUG_CC_UNUSED | XDEBUG_CC_DEAD_CODE);
a('first');
a('second');
a('third');
a('default');
$coverage = xdebug_get_code_coverage();
xdebug_stop_code_coverage();
//EVALUATE (not part of proof)
print_r(
[
'phpversion(\'xdebug\')' => phpversion('xdebug'),
'phpversion()' => phpversion(),
'php_sapi_name()' => php_sapi_name()
]
);
print_r($coverage);
?>
{code} When executing above code via CLI, following output is generated: {code}
Array
(
[phpversion('xdebug')] => 2.6.0
[phpversion()] => 7.0.28-0ubuntu0.16.04.1
[php_sapi_name()] => cli

Still reproducible using xdebug 2.6.1. |

Do you have opcache installed and enabled for the PHP-FPM install? |

> Do you have opcache installed and enabled for the PHP-FPM install? In the provided examples, opcache was installed and enabled. I performed some tests now using PHP 7.0.32-0ubuntu0.16.04.1. It's worth to notice that the results slightly differ when having opcache enabled/disabled, but issue in general still exists: Result having opcache enabled: {code} Array ( [phpversion('xdebug')] => 2.6.0 [phpversion()] => 7.0.32-0ubuntu0.16.04.1 [php_sapi_name()] => fpm-fcgi ) Array ( [/intproj/users/erik/switch_case.php] => Array ( [5] => 1 [6] => 1 [7] => 1 [8] => -1 [9] => 1 [10] => 1 [11] => -1 [12] => 1 [13] => 1 [15] => 1 [16] => 1 [18] => 1 [23] => 1 [24] => 1 [25] => 1 [26] => 1 [28] => 1 ) ) {code} Result having opcache disabled: {code} Array ( [phpversion('xdebug')] => 2.6.0 [phpversion()] => 7.0.32-0ubuntu0.16.04.1 [php_sapi_name()] => fpm-fcgi ) Array ( [/intproj/users/erik/switch_case.php] => Array ( [5] => 1 [6] => 1 [7] => 1 [8] => -1 [9] => 1 [10] => 1 [11] => -1 [12] => 1 [13] => 1 [15] => 1 [16] => 1 [18] => 1 [19] => -2 [23] => 1 [24] => 1 [25] => 1 [26] => 1 [28] => 1 ) ) {code} |

Also reproducible using php 7.2: opcache enabled: {code} Array ( [phpversion('xdebug')] => 2.6.0 [phpversion()] => 7.2.10-0ubuntu0.18.04.1 [php_sapi_name()] => fpm-fcgi ) Array ( [/intproj/users/erik/switch_case.php] => Array ( [4] => 1 [5] => -1 [6] => 1 [7] => 1 [8] => -1 [9] => 1 [10] => 1 [11] => -1 [12] => 1 [13] => 1 [15] => 1 [16] => 1 [18] => 1 [23] => 1 [24] => 1 [25] => 1 [26] => 1 [28] => 1 ) ) {code} opcache disabled: {code} Array ( [phpversion('xdebug')] => 2.6.0 [phpversion()] => 7.2.10-0ubuntu0.18.04.1 [php_sapi_name()] => fpm-fcgi ) Array ( [/intproj/users/erik/switch_case.php] => Array ( [4] => 1 [5] => -1 [6] => 1 [7] => 1 [8] => -1 [9] => 1 [10] => 1 [11] => -1 [12] => 1 [13] => 1 [15] => 1 [16] => 1 [18] => 1 [19] => -2 [23] => 1 [24] => 1 [25] => 1 [26] => 1 [28] => 1 ) ) {code} |

I will have a look at this after Xdebug 2.7.0 has been released. I haven't reproduced it yet, so will leave the issue in "acknowledged" for now. |
