Upgrading from Magento 1.9 to OpenMage 19.4.23 with PHP 8.1 corrupts HTML templates

[djixas]

Preconditions (*)

1. Magento 1.9.4.5
2. OpenMage 19.4.23
3. PHP 8.1

Steps to reproduce (*)

1. Take any Magento 1.9 install and upgrade to OpenMage, then enable PHP 8.1, this might also work on default OpenMage, I am not sure
2. Now try to place an order, click admin forgot pass or anything else, so you get email from TEMPLATES

Expected result (*)

1. It should display emails correctly

Sample "Test" email displays this content with PHP 7.4:

Name:
Email:
Telephone:

Comment: This is a test template email - your email settings are correct!

Actual result (*)

1. [Screenshots, logs or description]
   

Sample "Test" email displays this content with PHP 8.1:

=0A=0AName: =0AEmail: =0ATelephone: =0A=0AComment: This is a test template email - your email settings are correct!

Tested also with https://github.com/icecubenz-open-mage/Icecube_CustomEmailServer just to be safe, same issue, but the issue disappears if I downgrade to PHP 7.4, then email templates work properly. And it's for all emails, forgot admin pass, etc. Already tried reloading all email templates, same issue.

PHP ini settings / modules are identical.

P.S. Tested with two different Magento upgrades, one done via old school upgrade script of yours, other is by replacing all old files with OpenMage. It also keeps generating mailformed address errors:

A message that you sent contained one or more recipient addresses that were incorrectly constructed:

=?utf-8?B??= <>: missing or malformed local part

This address has been ignored. There were no other addresses in your message, and so no attempt at delivery was possible.

------ This is a copy of your message, including all the headers. ------

To: =?utf-8?B??= <>
Subject: =?utf-8?B?Q29udGFjdCBGb3Jt?=

The reporting is not the most appropriate to describe the issue but I confirm its existence. Here are the steps to reproduce it.

Place an order as a customer. Once you get the confirmation email check its content. Here is what I am seeing in MailHog.

1. This is for HTML content - EMPTY!

2. This is for Plain text

3. This is the Source with Headers

Something went wrong at some point and I can't say when, but this issue must be fixed as quickly as possible. I don't think it's coming from the phtml templates because no changes were made in the last years. Most likely a change in a PHP file affects all the messages format sent from the website.

May be it is related to issue #274.

great find @kiatng!

@djixas @addison74 could you try to changing vendor/shardj/zf1-future/library/Zend/Mail/Transport/Sendmail.php and replace public $EOL = PHP_EOL; with public $EOL = "\r\n"; and see if it works?

[addison74]

I will test this report in more detail because I can no longer reproduce it. I didn't make any changes, I installed the latest version of OpenMage 20 and I run it with PHP 8.1 and 8.2 and PR #3181. Please try to test it and let me know what results you get. If it is coming from ZF1-Future, we must report it to be fixed so that everyone can update now that the library has been outsourced.

Replaced sendmail.php with the edited and all emails are working fine still, even after PHP 8.1 switch, same on both sites :) yayyy

@djixas - What OS are use using? Windows?

I am asking this because digging for this issue I found that for Windows OS's the line ending must be \r\n and for Linux flavors PHP_EOL. Here some ideas

I managed to reproduced this issue on a shared host running PHP8.1. @fballiano fix on public $EOL = "\r\n"; works on Linux system.
