Bug #72050 [NEW]: Problems loading XSLT style sheets from some, but not all, PHP-FPM workers

From: dirkjan at ochtman dot nl Operating system: Linux PHP version: 5.6.20 Package: FPM related Bug Type: Bug Bug description:Problems loading XSLT style sheets from some, but not all, PHP-FPM workers Description: ------------ In one of my legacy websites, I'm using XSLT using the XSLTProcessor class from the xslt extension: function process() { $xslt = new XSLTProcessor(); $xslt->importStylesheet($this->xsl); foreach ($this->params as $name => $value) { $xslt->setParameter('', $name, $value); } return $xslt->transformToXML($this->xml); } The XSLT stylesheet I'm using also does some includes, with paths relative to the executed PHP script: <xsl:include href="assets/xsl/basic.xsl" /> However, since migrating to PHP-FPM, I've found that sometimes, the worker processes get into a state where some workers work correctly, however some workers fail to find the included XSL sheets, resulting in errors: Warning: XSLTProcessor::importStylesheet(): I/O warning : failed to load external entity "/var/www/hebe.nl/http/assets/xsl/basic.xsl" in /var/www/hebe.nl/http/include/classes.sys.php on line 315 Warning: XSLTProcessor::importStylesheet(): compilation error: file /var/www/hebe.nl/http/ line 14 element include in /var/www/hebe.nl/http/include/classes.sys.php on line 315 Warning: XSLTProcessor::importStylesheet(): xsl:include : unable to load /var/www/hebe.nl/http/assets/xsl/basic.xsl in /var/www/hebe.nl/http/include/classes.sys.php on line 315 When restarting PHP-FPM, the problem fixes itself, but that's not a very nice way to solve it. :) Expected result: ---------------- XSLT includes should work (or not) consistently. Actual result: -------------- Reloading the page sometimes results in the correct HTML, sometimes has errors. -- Edit bug report at https://bugs.php.net/bug.php?id=72050&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72050&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72050&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72050&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72050&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72050&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72050&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72050&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72050&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72050&r=support Expected behavior: https://bugs.php.net/fix.php?id=72050&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72050&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72050&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72050&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72050&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72050&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72050&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72050&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72050&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72050&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72050&r=mysqlcfg
