ext_emconf has

'depends' => array(
'core' => '',
),

but "core" doesnt' exists :)

I know the flowchart is strict about caches beeing active at any point of time, but something i often have to deal with is that compare database always wants to drop the cache tables beacuse there is no database backend configured and i often forget about that.

Would you, just to know before i provide a PR, allow a condition that disables the uncaching for install tool requests or do you want to keep it nice and clean?

When using Assets ViewHelper to merge all registered assets they are not reloaded when using Uncache extension.

This extension is designed to disable only native TYPO3 caches or should also cooperate with Assets ?

Since https://git.typo3.org/Packages/TYPO3.CMS.git/commit/d7b922f4a2e5ab64459830cd021fc085c8c2de46 the usage of $GLOBALS['typo3CacheManager'] and $GLOBALS['typo3CacheFactory'] are deprecated. Deprecation message:

Usage of $GLOBALS['typo3CacheManager'] and $GLOBALS['typo3CacheFactory'] are deprecated since 6.2 will be removed in two versions. Use \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\CMS\Core\Cache\CacheManager') or dependency injection to access the singletons.'

On latest TYPO3 6.2 (git master) thus uncache throws the following exeption:

Fatal error: Uncaught exception 'TYPO3\CMS\Extbase\Reflection\Exception\PropertyNotAccessibleException' with message 'The property "cacheConfigurations" on the subject does not exist.

Following qick'n'dirty hack (caching is definitly too complex for me, so please review very intensely) seems to work with a minimal FluidTYPO3 (TYPO3 6.2, flux, fluidpages and fluidcontent). I had to add some conditions (extbase_datamapfactory_datamap, extbase_typo3dbbackend_tablecolumns and fluid_template) to get rid of exeptions a la

1203699034: A cache with identifier "extbase_datamapfactory_datamap" does not exist.

My replacement for line 16-24 in ext_localconf.php

if (isset($GLOBALS['typo3CacheManager']) === TRUE) {
    if (version_compare(TYPO3_branch, '6.2', '<')) {
        $configurations = \TYPO3\CMS\Extbase\Reflection\ObjectAccess::getProperty($GLOBALS['typo3CacheManager'], 'cacheConfigurations', TRUE);
        $caches = \TYPO3\CMS\Extbase\Reflection\ObjectAccess::getProperty($GLOBALS['typo3CacheManager'], 'caches', TRUE);
        $GLOBALS['typo3CacheManager'] = new \TYPO3\CMS\Uncache\Override\Core\Cache\CacheManager();
        $GLOBALS['typo3CacheManager']->setCacheConfigurations($configurations);
        \TYPO3\CMS\Extbase\Reflection\ObjectAccess::setProperty($GLOBALS['typo3CacheManager'], 'caches', $caches, TRUE);
        \TYPO3\CMS\Core\Utility\GeneralUtility::setSingletonInstance('TYPO3\\CMS\\Core\\Cache\\CacheManager', $GLOBALS['typo3CacheManager']);
        unset($configurations, $caches);
    } else {
        $typo3CacheManager = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\CMS\Core\Cache\CacheManager');
        $configurations = \TYPO3\CMS\Extbase\Reflection\ObjectAccess::getProperty($typo3CacheManager, 'cacheConfigurations', TRUE);
        if (!isset($configurations['extbase_datamapfactory_datamap'])) {
            $configurations['extbase_datamapfactory_datamap'] = \TYPO3\CMS\Extbase\Reflection\ObjectAccess::getProperty($typo3CacheManager, 'defaultCacheConfiguration', TRUE);

Hi @NamelessCoder !
When EXT:uncache is active the 'Database analyzer' of Install Tool throws this error:

Detected Fatal Error
Call to a member function getBackend() on a non-object in /var/www/dummy.com/htdocs/typo3_src/typo3/sysext/core/Classes/Cache/Cache.php on line 95

In my workflow I use this tool pretty often while developing and I wonder if is easy to fix this without the need to disable/enable EXT:uncache.

Thanks anyway!

Thanks..

Im getting this error with 6.1.7.
#1231259656: The cache configuration for cache "fluid_template" was not an array as expected. (More information)

InvalidArgumentException thrown in file
/var/www/clients/client1/web10/web/typo3_src-6.1.7/typo3/sysext/core/Classes/Cache/CacheManager.php in line 88.

I can't install this extension due to this fatal error:

Call to a member function getBackend() on a non-object in C:\xampp\www\dev3\htdocs\v15\typo3\sysext\core\Classes\Cache\Cache.php on line 105
