MacOs M1 Cannot connect to Atlas After upgrade driver about mongo-php-library

[alcaeus]

Hi @samuelexyz, the segmentation fault happens due to the driver being compiled with Secure Transport as SSL library but php-fpm being compiled with OpenSSL. Compiling the driver using OpenSSL fixes the issue. Please note that until we get to PHPC-1017, specifying these options when running pecl install is impossible, so you'll have to configure the driver manually. Instructions for this can be found in the installation docs. Please note that due to an issue with homebrew (which I haven't been able to work around; see mongodb/mongo-php-driver#1405), you also need to specify the homebrew include directory using CFLAGS. I used the following configure call in my tests:

CFLAGS=-I/opt/homebrew/include ./configure --enable-mongodb-developer-flags --with-mongodb-ssl=openssl

I've created mongodb/mongo-php-driver#1463, which targets the v1.16 branch and will be released in an upcoming patch release. With the steps above, you should be able to work around the issue in the meantime; the changes merely change the detection mechanism to prefer OpenSSL over Secure Transport.

[alcaeus]

Just a minor update: we're releasing the fix in the 1.17 version of the driver. After consideration, we decided that this was too big a change for a 1.16 patch release. I expect 1.17 to be released in the near future, but in the meantime you can use the instructions above to work around the issue.

Hi @samuelexyz, sorry for the lack of reply. I managed to reproduce the issue on my machine and have created PHPC-2280 to track this internally. I'm still investigating why the crash happens, as it is somewhere within system libraries and only triggered when connecting through FPM, but not through the CLI SAPI.

[samuelexyz]

Hi @alcaeus Thank you i will follow PHPC-2280

[alcaeus]

Thank you for reporting the issue and including a debug log from the driver. From it, I can see two connection attempts (both starting with the "Connection String [...]" line. The first one abruptly ends while encoding a document, but the second attempt starts right after that, so I assume the server was still alive. This second attempt continues further, and then abruptly stops when creating the TLS stream. Can you confirm that the time of that last log entry is consistent with when the php-fpm process crashes?

Also, it would be helpful if you could try to reproduce it in the command-line. I ran a quick test with an Atlas cluster on my M1 Pro but couldn't reproduce a crash.

[samuelexyz]

Of course this is the test code:

<?php

require __DIR__ . '/vendor/autoload.php';

use MongoDB\Client;
use MongoDB\Driver\ServerApi;

ini_set('mongodb.debug', '1');

$uri ="mongodb+srv://<url>/?retryWrites=true&w=majority;";
// Specify Stable API version 1
$apiVersion = new ServerApi(ServerApi::V1);
// Create a new client and connect to the server
$client = new MongoDB\Client($uri, [], ['serverApi' => $apiVersion]);
try {
    // Send a ping to confirm a successful connection
    $client->selectDatabase('admin')->command(['ping' => 1]);
    echo "Pinged your deployment. You successfully connected to MongoDB!\n";
} catch (Exception $e) {
    printf($e->getMessage());
}
?>
