Bug #77594 [NEW]: ob_tidyhandler flips tidy.clean_output option for lifetime of php-fpm process

From: da dot net dot php dot bugs at daniel dot priv dot no Operating system: Linux PHP version: 7.2.15 Package: Unknown/Other Function Bug Type: Bug Bug description:ob_tidyhandler flips tidy.clean_output option for lifetime of php-fpm process Description: ------------ 1. Set tidy.clean_output = Off in php.ini. 2. Run ob_start('ob_tidyhandler'); in testA.php The page is output with cleaned output as expected. 3. Run any other PHP file without calling the same function. The output is also unexpectedly cleaned. The option is unexpectedly flipped for every subsequent request processed by the same php-fpm process. I may be wrong (C isn't my strongest language), but I believe this just flips the option. https://github.com/php/php-src/blob/db0079023421b8048f090ee04adb992e09132553/ext/tidy/tidy.c#L1172 -- Edit bug report at https://bugs.php.net/bug.php?id=77594&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77594&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77594&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77594&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77594&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77594&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77594&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77594&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77594&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77594&r=support Expected behavior: https://bugs.php.net/fix.php?id=77594&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77594&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77594&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77594&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77594&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77594&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77594&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77594&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77594&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77594&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77594&r=mysqlcfg
