Bug #80258 [NEW]: Windows Deduplication Enabled, seeing randon permission errors

From: josh dot manchester at dirxion dot com Operating system: Windows 2016 Standard PHP version: 7.4.11 Package: SQLite related Bug Type: Bug Bug description:Windows Deduplication Enabled, seeing randon permission errors Description: ------------ We have Windows deduplication enabled on our 2016 servers for several years but I think we found something out of whack with the latest PHP version. I originally upgraded from 7.4.7 to 7.4.11, when I had problems I then attempted to downgrade to 7.4.10 and the problem remained, but with 7.4.9 I have no issues. While our primary web product had some 'Unable to find resource' type errors loading, the simplest example I can provide is our health check script that we have setup for testing Database connectivity. On versions 7.4.11 and 7.4.10 the SQLite check fails with the error I provided under Actual Result. I am using the Windows PHP NTS build as provided on your site. I tested this on 2 servers, and each server would start to work if I either downgraded to php 7.4.9, or disabled Deduplication and ran the powershell script to unoptimize all the files. Test script: --------------- <?php include 'includes/autoload.php'; //SQLite $db_path = 'abb20htm.db3'; $db = new PDO('sqlite:'.$db_path);//connection $bookdb3_class = new BookDb3($db); $sgt = '3';//res $row = $bookdb3_class->getFirstPageLabel($sgt)->getResults(); //$bookdb3_class->printOut(); //print_r($row); $pageLabel = $row['PageLabel']; if ($pageLabel == '1') echo 'SQLite test succeeded'; else echo 'SQLite test failed'; echo '<br>'; ?> Expected result: ---------------- Via a browser, we expect to see... SQLite test succeeded Actual result: -------------- Note: My original health check script had some MySQL and MSSQL health checks that I removed in my example, so line 39 is no longer accurate.
