Description ----------- With @Toflar we have discovered by accident that if a URL is double-encoded (for some reason, doesn't matter) the Contao's `RouteProvider` will eventually throw an error trying to query a database. ``` URL original: drachenlochmuseum-v%25c3%25a4ttis.html URL decoded: drachenlochmuseum-v%c3%a4ttis.html URL decoded 2nd time: drachenlochmuseum-vättis.html ``` The decoded URL is used in the database query and that fails because the database driver would like to replace wildcards `%c` with parameters that were not provided. Stack trace: ``` Exception: Too few arguments to build the query string #27 vendor/contao/core-bundle/src/Resources/contao/library/Contao/Database/Statement.php(304): replaceWildcards #26 vendor/contao/core-bundle/src/Resources/contao/library/Contao/Database/Statement.php(249): execute #25 vendor/contao/core-bundle/src/Resources/contao/library/Contao/Model.php(1102): find #24 vendor/contao/core-bundle/src/Resources/contao/library/Contao/Model.php(973): findBy #23 vendor/contao/core-bundle/src/Framework/Adapter.php(38): __call #22 vendor/contao/core-bundle/src/Routing/RouteProvider.php(493): findPages #21 vendor/contao/core-bundle/src/Routing/RouteProvider.php(88): getRouteCollectionForRequest #20 vendor/contao/core-bundle/src/Routing/LegacyRouteProvider.php(43): getRouteCollectionForRequest #19 vendor/symfony-cmf/routing/src/NestedMatcher/NestedMatcher.php(141): matchRequest #18 vendor/contao/core-bundle/src/Routing/Matcher/LegacyMatcher.php(69): matchRequest #17 vendor/symfony-cmf/routing/src/DynamicRouter.php(271): matchRequest #16 vendor/symfony-cmf/routing/src/ChainRouter.php(188): doMatch #15 vendor/symfony-cmf/routing/src/ChainRouter.php(158): matchRequest #14 vendor/symfony/http-kernel/EventListener/RouterListener.php(115): onKernelRequest #13 vendor/symfony/event-dispatcher/EventDispatcher.php(212): doDispatch #12 vendor/symfony/event-dispatcher/EventDispatcher.php(44): dispatch #11 vendor/symfony/http-kernel/HttpKernel.php(126): handleRaw #10 vendor/symfony/http-kernel/HttpKernel.php(67): handle #9 vendor/symfony/http-kernel/Kernel.php(198): handle #8 vendor/symfony/http-kernel/HttpCache/SubRequestHandler.php(85): handle #7 vendor/symfony/http-kernel/HttpCache/HttpCache.php(448): forward #6 vendor/symfony/framework-bundle/HttpCache/HttpCache.php(57): forward #5 vendor/symfony/http-kernel/HttpCache/HttpCache.php(420): fetch #4 vendor/contao/manager-bundle/src/HttpKernel/ContaoCache.php(46): fetch #3 vendor/symfony/http-kernel/HttpCache/HttpCache.php(317): lookup #2 vendor/symfony/http-kernel/HttpCache/HttpCache.php(192): handle #1 vendor/friendsofsymfony/http-cache/src/SymfonyCache/EventDispatchingHttpCache.php(98): handle #0 web/app.php(58): null ``` Commits ------- 8ae25820 Fix a potential error if the URL has percentage in it 8caaf252 Fix unit tests 509f7624 Correctly encode the page aliases

This PR simply ignores it if not set. Commits ------- e54dc2b8 fix warning when legacy keywords are present

This PR removes the
System::getKernel()method as discussed. You can still get the kernel object using one of the following:The first method assumes that the container is available, which however is not the case during the bundle autoloading process. I have therefore used the global variable variant.
