Previous Comments: ------------------------------------------------------------------------ [2019-12-08 20:00:02] requinix@php.net We are not familiar with PrestaShop or how it works. TS and NTS builds are different in more ways that just threading. Please file a bug with PrestaShop first, and if they can identify a bug in PHP then we can revisit this. ------------------------------------------------------------------------ [2019-12-08 19:57:13] michael dot vorisek at email dot cz Description: ------------ When PHP uses only 1 thread, i.e. CGI or CLI, it should produce exactly the same output, right? But after days of trouble shooting I finally find the issue with PrestaShop installer. The issue is PHP on Windows. When you download the latest version of PrestaShop https://github.com/PrestaShop/PrestaShop/releases/download/1.7.6.2/prestashop_1.7.6.2.zip , unzip it and a) install it from CLI using admin/install_cli.php b) OR install thru web using PHP CGI the install always fail with NTS PHP (with error Template "C:\wamp64\www\ps\mails\themes\modern\core\account.html.twig" is not defined.), but always succeed when run with TS PHP. I tested it on multiple Windows systems and two versions of PHP - 7.3.9 and 7.3.12/latest. The install always completes with the TS version of PHP, but always fail with the NTS one. I am posting it here and not in the PrestaShop repo, as this seems like some core PHP issue. Can you please reproduce and fix? Test script: --------------- see description Expected result: ---------------- no difference between TS and NTS version, i.e. the PrestaShop installed always succeed Actual result: -------------- TS build is working correctly, but the NTS build of the same PHP version (and config, file location, ...) does something unclear differently ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78931&edit=1
