mime.php: Deprecated type string under PHP 8.1.24

[ozgurkazancci]

Hi,

I got the following logs in Roundcube's own error log file;

[31-Oct-2023 20:57:51 Europe/Helsinki] PHP Deprecated: file_exists(): Passing null to parameter #1 ($filename) of type string is deprecated in /var/www/rcube/vendor/pear/mail_mime/Mail/mime.php on line 486

Wanted to write about it here.

Roundcube version: 1.6.4
PHP version: 8.1.24

Regards.

I will fix this in Mail_Mime code, but this warning tells me there might be some other error leading to this one. Are you able to reproduce?

Reproduced it again, got one more line, before the one above appears;

<2t0fu6cp> PHP Error: info@mywebsite.com can't read /tmp/RCMTEMPattmnt65414c97cb8a2367966745 (not in temp_dir) in /var/www/rcube/plugins/filesystem_attachments/filesystem_attachments.php on line 245 (POST /webmail/?_task=mail&_unlock=loading1698778266108&_framed=1&_action=send)

The PHP error above occurs due to misconfiguration of "$config['temp_dir']", still wanted to report it here, thinking it would help perhaps for a better error-handling in such cases?

Regards.

Warning fixed in pear/Mail_Mime@5ace0d7d2405e.
