TYPO3 Core

Hi,
while the above happened for an upgraded version it happens also for a newly installed blank typo3 9.5 version, installing introduction package, activating the Recycler breaks the system happens on Win10 install with xampp 722.

Looking to the error log in php I see.

[Tue Jan 01 19:56:00.566008 2019] [php7:notice] [pid 15980:tid 1988] [client ::1:56376] PHP Fatal error: Uncaught Error: Call to a member function isPackageActive() on null in C:\\xampp\\xampp722\\htdocs\\typo3_95\\typo3\\sysext\\core\\Classes\\Utility\\ExtensionManagementUtility.php:148\nStack trace:\n#0 C:\\xampp\\xampp722\\htdocs\\typo3_95\\typo3\\sysext\\core\\Classes\\Controller\\ErrorPageController.php(54): TYPO3\\CMS\\Core\\Utility\\ExtensionManagementUtility::extPath('core', 'Resources/Priva...')\n#1 C:\\xampp\\xampp722\\htdocs\\typo3_95\\typo3\\sysext\\core\\Classes\\Utility\\GeneralUtility.php(3662): TYPO3\\CMS\\Core\\Controller\\ErrorPageController->__construct()\n#2 C:\\xampp\\xampp722\\htdocs\\typo3_95\\typo3\\sysext\\core\\Classes\\Error\\ProductionExceptionHandler.php(59): TYPO3\\CMS\\Core\\Utility\\GeneralUtility::makeInstance('TYPO3\\\\CMS\\\\Core\\\\...')\n#3 C:\\xampp\\xampp722\\htdocs\\typo3_95\\typo3\\sysext\\core\\Classes\\Error\\AbstractExceptionHandler.php(50): TYPO3\\CMS\\Core\\Error\\ProductionExceptionHandler->echoExceptionWeb(Object(TYPO3\\CMS\\Core\\Cache\\Exception\\NoSuchCacheException))\n#4 [internal function]: TYPO3\\CMS\\Core\\Error\\AbstractExceptionHandler->hand in C:\\xampp\\xampp722\\htdocs\\typo3_95\\typo3\\sysext\\core\\Classes\\Utility\\ExtensionManagementUtility.php on line 148, referer: http://localhost/typo3_95/typo3/index.php?route=%2Fmain&token=11cd6aff48e5a9454a9badb94440efcb00044ca3

I got the same problems (Xampp on Windows 10), but I was able to install system extensions like recycler and linkvalidator albeit with some hiccups, while when installing EXT:vhs I failed: every time the system resets the connection and the only way to recover it is removing every vhs reference from PackageStates.php and LocalConfiguration.php and clear everything from Install tool.

Connected the ticket, which changed the way the caching worked

I think this bug is unrelated to the caching changes of the PackageManager.
It could be related to the early creation of the assets cache [1], as Eckard's logs show that a no such scache exception is thrown TYPO3\CMS\Core\Cache\Exception\NoSuchCacheException which is happening prior the creation of the PackageManager.

The (production) ExceptionHandler then tries to generate html for that exception using the ErrorPageController which itself uses ExtensionManagementUtility::extPath(), which then tries to use the PackageManager object to retrieve a package path – but, that PackageManager is about to be created and not available. The static variable in ExtensionManagementUtility pointing to the PackageManager has not been set yet, which now causes another exception inside of the exception handler. oops.

To get more information about the first exception (e.g. which cache is missing and why), please switch to the DebugExceptionHandler by setting ['SYS']['displayErrors'] => 1 in LocalConfiguration.php (that should prevent the second exception inside the exception handler. Then post the output or a screenshot of the DebugExceptionHandler output here.

• Some cache could not be found/created (first exception)
• ErrorPageController needs to be adapted to work when PackageManager is not yet available (second exception)

Hi,

after a lot of hints (thanks to all) the reason was found.

I had not changed the ThreadStackSize in the httpd.conf

<IfModule mpm_winnt_module>
ThreadStackSize 8388608
</IfModule>

After changing this the crash does not happen any more.

Thanks for the help
Eckard.
