Cache prefixing logic rewrite, session scoping improvements, tests refactor (#43)
* Run cache tests on all supported drivers * update ci healthcheck for memcached * remove memcached healthcheck * fix typos in test comments, expand internal.md [ci skip] * add empty line [ci skip] * switch to using $store->setPrefix() * add dynamodb * refactor try-finally to try-catch * remove unnecessary clearResolvedInstances() call * add dual Cache:: and cache() assertions * add apc * Flush APCu cache in test setup * Revert "add dual Cache:: and cache() assertions" This reverts commit a0bab162fbe2dd0d25e7056ceca4fb7ce54efc77. * phpstan fix * Add logic for scoping 'file' disks to FilesystemTenancyBootstrapper * minor changes, add todos * refactor how the session.connection is used in the DB session bootstrapper * add session forgery prevention logic to the db session bootstrapper * only use the fs bootstrapper for file disk in 'cache data is separated' dataset * minor session scoping test changes * Add session scoping logic to FilesystemTenancyBootstrapper, correctly update disk roots even with storage_path_tenancy disabled * Fix code style (php-cs-fixer) * update docblock * make not-null check more explicit * separate bootstrapper tests, fix swapped test names for two tests * refactor cache bootstrapper tests * resolve global cache todo * expand tests: session separation tests, more filesystem separation assertions; change prefix_base-type config keys to templates/formats * add apc session scoping test, various session separation bugfixes * phpstan + minor logic fixes * prefix_format -> prefix * fix database session separation test * revert composer.json changes, update laravel dependencies to expected next release * only run session scoping logic in cache bootstrapper for redis, memcached, dynamodb, apc; update gitattributes * tenancy.central_domains -> tenancy.identification.central_domains * db session separation test: add datasets --------- Co-authored-by: PHP CS Fixer <phpcsfixer@example.com>
