TYPO3 Core

Hello Core-Team,

I know...current git state of TYPO3 is beta, but there are some basic functions in TYPO3 which still needs some love. I already have created an ticket regarding dependencies in PackageStates.php. Now I have found a second bug:

Here a simplified visualisation of: $this->packageStatesConfiguration['packages']:

array(
    'about' => array(...),
    'backend' => array(...),
    'core' => array(...),
    'yellowpages' => array(...), <--This extension has a dependency to jw_categories
    'files' => array(...), <-- I have deleted this extension in extManager
    'tt_news' => array(...),
    'jw_categories' => array(...),
)

If I delete "files" you call:

protected function unregisterPackageByPackageKey($packageKey) {
    unset($this->packages[$packageKey]);
    unset($this->packageKeys[strtolower($packageKey)]);
    unset($this->packageStatesConfiguration['packages'][$packageKey]);
    $this->sortAndSavePackageStates();
}

In this function you remove files correctly, but you call $this->sortAndSavePackageStates() and this a mistake. $this->sortAndSavePackageStates() only works with already registered packages. So our packages array looks like:

array(
    'about' => array(...),
    'backend' => array(...),
    'core' => array(...),
    'yellowpages' => array(...), <--This extension has a dependency to jw_categories
);

$this->sortAndSavePackageStates() cannot find package jw_categories, because it is not registered already. Backtrace:

PHP Fatal error:  Uncaught exception 'UnexpectedValueException' with message 'The package "yellowpages2" depends on "jw_categories" which is not present in the system.' in /Applications/MAMP/htdocs/typo3_src/typo3/sysext/core/Classes/Package/PackageManager.php:636
