TYPO3 Core

Hi Nicole

This can't be solved easily and IMHO separate between local and TER version is much better, than a single one. You could additionally register your slot to the signal

TYPO3\CMS\Extensionmanager\Utility\InstallUtility::afterExtensionInstall

Tried it with the code below in ext_localconf.php but it didn't executed Aimeos\Aimeos\Setup->executeOnSignal():

$signalSlotDispatcher->connect(
    'TYPO3\\CMS\\Extensionmanager\\Utility\\InstallUtility',
    'afterExtensionInstall',
    'Aimeos\\Aimeos\\Setup',
    'executeOnSignal'
);

This works at least for not manually uploaded extensions:

$signalSlotDispatcher->connect(
    'TYPO3\\CMS\\Extensionmanager\\Service\\ExtensionManagementService',
    'hasInstalledExtensions',
    'Aimeos\\Aimeos\\Setup',
    'executeOnSignal'
);
