Req #78555 [NEW]: Disable dblink cleanup
From: erik at coretech dot se
Operating system:
PHP version: 7.3.9
Package: MySQLi related
Bug Type: Feature/Change Request
Bug description:Disable dblink cleanup
Description:
------------
When building daemon processes with php that requires the parent process
to create a persistent database connection. The cleanup of the child
process closes the parents database connection. A way to disable this
cleanup on a object basis would make php better for daemon projects.
This problem applies to other file descriptors aswell but the most
problematic is the mysqli dblink resource.
Test script:
---------------
<?php
function query_db($dbo) {
if(!mysqli_real_query($dbo, "SELECT 1"))
die("Unable to query database: " . mysqli_error($dbo) .
" (" . mysqli_errno($dbo) . ")\n");
if(($res = mysqli_store_result($dbo)) === FALSE)
die("Unable to store result: " . mysqli_error($dbo) . "
(" . mysqli_errno($dbo) . ")\n");
echo "Successful query\n";
}
$dbo = mysqli_init();
if (!mysqli_real_connect($dbo, 'dbserver', 'dbuser', 'dbpwd')) {
die("Unable to connect to the database\n");
}
query_db($dbo);
$pid = pcntl_fork();
if ($pid == -1) {
die("Could not fork\n");
} else if($pid) {
// Parent
pcntl_wait($status);
query_db($dbo);
} else {
// Child
// mysqli_disable_cleanup($dbo, TRUE);
exit(0);
}
Expected result:
----------------
Successful query
Successful query
Actual result:
--------------
Successful query
PHP Warning: mysqli_real_query(): MySQL server has gone away in
/tmp/test.php on line 5
PHP Warning: mysqli_real_query(): Error reading result set's header in
/tmp/test.php on line 5
